    Description: We report two Arctic species of incirrate octopods new to science. One is formally described here as Muusoctopus aegir Golikov, Gudmundsson & Sabirov sp. nov. while the other, Muusoctopus sp. 1, is not formally described due to a limited number of samples (all are immature individuals). These two species differ from each other, and from other Muusoctopus, especially in: 1) absence of stylets (in M. aegir sp. nov.); 2) proportions of mantle and head; 3) funnel organ morphology (W-shaped with medial and marginal limbs of equal length in M. aegir sp. nov., or medial are slightly longer; V V-shaped with medial limbs slightly longer and broader than marginal in Muusoctopus sp. 1); 4) sucker and gill lamellae counts; 5) relative arm length and sucker diameter; and 6) male reproductive system relative size and morphology. Species of Muusoctopus now comprise four of 12 known Arctic cephalopods. Additionally, this study provides: a) new data on the morphology and reproductive biology of M. johnsonianus and M. sibiricus, and a diagnosis of M. sibiricus; b) the equations to estimate mantle length and body mass from beak measurements of M. aegir sp. nov. and M. johnsonianus; c) a cytochrome c oxidase subunit I gene barcode for M. sibiricus; d) new data on the ecology and distribution of all studied species; and e) a data table for the identification of northern North Atlantic and Arctic species of Muusoctopus.

    Description: Holothurians are the dominant megabenthic deposit feeders in the Peru Basin (SE Pacific) and feed to various degrees of selectivity on a heterogenous pool of sedimentary detritus, but drivers of feeding selectivity and diet preferences for most holothurian species are unknown. This study reconstructs the diets of 13 holothurian species of the orders Elasipodida, Holothuriida, and Synallactida. Bulk stable isotope analyses (δ13C, δ15N) of holothurian body wall and gut wall tissues, gut contents, and feces were combined with compound-specific stable isotope analyses of amino acids, phospholipid-derived fatty acids, and neutral-lipid-derived fatty acids in the body wall. We further assessed how holothurians in the Peru Basin partition their resources and calculated how much of the daily particulate organic carbon (POC) flux to the area is ingested by them using information about gut contents of nine species. To assess the dependence of holothurians on fresh phytodetritus, we performed in situ pulse-chase experiments using 13C- and 15N-enriched phytodetritus. By measuring the uptake of this phytodetritus in fatty acids and amino acids and by comparing it with the presence of these compounds in the sediment, we calculated net accumulation and net deficiency for specific fatty acids and amino acids and discussed how climate change might affect the dependence on specific compounds. A Sørensen–Dice coefficient-based cluster analysis using data from trophic levels, levels of heterotrophic re-synthesis of amino acids, feeding selectivity, and food sources/diet suggested two major trophic groups with two optional subgroups each. Species-specific traits of locomotion, tentacle morphology, and gut structure likely allow resource partitioning and differences in selectivity among the holothurians, of which a subpopulation of 65% of all specimens can ingest 4 to 27% of the daily POC flux to the Peru Basin. Holothurians are specifically dependent on the uptake of arachidonic acid from phytodetritus, while most essential amino acids are available in the Peru Basin in sufficient concentrations.

    Description: Geochemical study of volcaniclastic material and radiocarbon dating of charred plant debris from Holocene deposits of the Guram site, which is located in vicinity of Vetrovoi Isthmus on Iturup Island, demonstrate that an explosive eruption (VEI 4-5) occurred there about 2000 years ago. The geochemical and age similarity with the tephra of marker layer CKr that was distinguished on Iturup, Urup, Simushir, Rasshua, and Matua islands of the Kuril Island Arc led to the conclusion that this eruption is possibly a source of this tephra. The data presented are proposed as a motivation for revision of the volcanic hazard on Iturup Island.

    Description: Variations in trace metal contents and sulfur isotope ratios (δ34S) within pyrite, at the scale of individual mineral grains, preserves a record of temporal fluctuations in the source of metals and sulfur as well as changes in the chemical composition and temperature of hydrothermal fluid during the evolution of the Brothers volcano, Kermadec arc, New Zealand. In this study, we analyzed pyrite from drill core recovered from two geochemically distinct hydrothermal systems at the Brothers volcano, the seawater-influenced NW Caldera (Site U1530) and magmatic-volatile-dominated Upper Cone (Site U1528) during the International Ocean Discovery Program’s Expedition 376. At the NW Caldera site, from 189 m below the seafloor, a seawater-derived hydrothermal fluid forming chlorite-rich alteration overprints early pyrophyllite + illite alteration. Within ~ 30 m of the seafloor at this same site, pyrite contains zones of high As content with a variable δ34S signature that ranges from -4.5 to 3.4‰ (n = 26). Values for δ34S 〉 0‰ record shallow mixing of seawater with upwelling hydrothermal fluids. In deeper parts of the system, but still within the chlorite-rich alteration zone, δ34S values 〉 0‰ are absent, indicating that relatively more sulfur is contributed from magmatic volatile degassing and SO2 disproportionation. In the pyrophyllite-rich alteration zone, pyrite contains Co-enriched cores that correspond to sharp changes in δ34S values from -5.3‰ to 4.6‰ (n = 68). Cobalt enrichment occurs in response to the mixing of seawater-derived hydrothermal fluid with Co-rich magmatic brines. At the Upper Cone site, a relatively constant supply of a low-salinity magmatic fluid results in pyrite grains that rarely exhibit any internal zonation in trace metal content. In pyrite where zonation does exist, a correlation between Cu and Sb and uniformly low δ34S values (〈 0‰) indicates a link between metal enrichment, the pulsed degassing of magmatic volatiles, and SO2 disproportionation.

    Description: In a volcanic crisis, authorized decision-makers must balance the social and economic costs of mitigating actions, such as evacuation, against the potential human losses if such actions are insufficient. In making their decisions, advice is needed from volcanologists on the eruption probability. Therefore, there should be a clear separation in the roles of volcanologists and decision-makers; the volcanologists should advise on the volcano hazard and alternative potential scenarios but refrain from involvement in making decisions. Currently, volcanologists are responsible for setting volcano alert levels. Given the small handful of distinct alert levels, there is inherent ambiguity and substantial uncertainty in the interpretation of individual levels. Furthermore, changing an alert level may automatically trigger actions by decision-makers. This would violate the principle of separation of responsibility and may result in unwelcome pressure being applied to volcanologists. Just as physicians can invoke medical ethics in resisting pressure to alter their advice, so volcanologists can invoke geoethics. Freedom to abide by their scientific beliefs is a basic tenet of geoethics.

    Description: Isolation and detection of microplastics (MP) in marine samples is extremely cost- and labor-intensive, limiting the speed and amount of data that can be collected. In the current work, we describe rapid measurement of net-collected MPs (net mesh size 300 µm) using a benchtop near-infrared hyperspectral imaging system during a research expedition to the subtropical North Atlantic gyre. Suspected plastic particles were identified microscopically and mounted on a black adhesive background. Particles were imaged with a Specim FX17 near-infrared linescan camera and a motorized stage. A particle mapping procedure was built on existing edge-finding algorithms and a polymer identification method developed using spectra from virgin polymer reference materials. This preliminary work focused on polyethylene, polypropylene, and polystyrene as they are less dense than seawater and therefore likely to be found floating in the open ocean. A total of 27 net tows sampled 2534 suspected MP particles that were imaged and analyzed at sea. Approximately 77.1% of particles were identified as polyethylene, followed by polypropylene (9.2%). A small fraction of polystyrene was detected only at one station. Approximately 13.6% of particles were either other plastic polymers or were natural materials visually misidentified as plastics. Particle size distributions for PE and PP particles with a length greater than 1 mm followed an approximate power law relationship with abundance. This method allowed at-sea, near real-time identification of MP polymer types and particle dimensions, and shows great promise for rapid field measurements of microplastics in net-collected samples.

    Description: Anthropogenic carbon dioxide (CO2) levels are rising to alarming concentrations in earth’s atmosphere, causing adverse effects and global climate changes. In the last century, innovative research on CO2 reduction using chemical, photochemical, electrochemical and enzymatic approaches has been addressed. In particular, natural CO2 conversion serves as a model for many processes and extensive studies on microbes and enzymes regarding redox reactions involving CO2 have already been conducted. In this review we focus on the enzymatic conversion of CO2 to carbon monoxide (CO) as the chemical conversion downstream of CO production render CO particularly attractive as a key intermediate. We briefly discuss the different currently known natural autotrophic CO2 fixation pathways, focusing on the reversible reaction of CO2, two electrons and protons to CO and water, catalyzed by carbon monoxide dehydrogenases (CODHs). We then move on to classify the different type of CODHs, involved catalyzed chemical reactions and coupled metabolisms. Finally, we discuss applications of CODH enzymes in photochemical and electrochemical cells to harness CO2 from the environment transforming it into commodity chemicals.

    Description: The role and conditions of liquid immiscibility or crystallization of sulfide phase during evolution of subduction-related magmas remains a debated topic, which bears relevance to the genesis of porphyry copper deposits and evolution of the continental crust. We studied rare volcanic rocks with inclusions of magmatic sulfides in olivine—the basalts of Medvezhya Mount in the Avachinsky group of volcanoes. The rocks belong to primitive (Mg# = 66 mol %) middle-K island-arc olivine basalts. Olivine with normal zoning predominates (~98%) among phenocrysts. The olivine compositions are typical for Kamchatka basalts, except for an unusual trend of increase of MnO content from 0.20 to 0.55 wt % and decrease of Fe/Mn from 60 to 35 with a change of olivine composition from Fo87.8 to Fo78.2. Olivine of this group contains numerous inclusions of spinel-group minerals varying in composition from chromium spinel to magnesian magnetite. Olivine phenocrysts with sulfide inclusions are characterized by the absence of or weak reverse zoning and reduced contents of Ca, Ni, Mn, Cr, and Al. The estimated crystallization temperatures are 1036–1241°C for olivine of the prevailing type and 1010–1062°C for sulfide-bearing olivine. The data suggest that crystallization of the main olivine population occurred under relatively shallow conditions and was accompanied by strong magma oxidation. On the contrary, the zoning pattern and compositional features of sulfide-bearing olivine suggest its xenogenic origin and the probable crystallization under deep-crustal conditions from low-temperature water-rich and/or low-Ca magmas. The results obtained confirm the possibility of saturation of oxidized island-arc magmas with sulfide phase at lower crustal conditions, but show that this process is rare and not typical for low-pressure crystallization stage.

    Description: Due to the increasing challenge of meeting human demands for metals from land-based resources, interest in extracting mineral ores from the deep sea has gained momentum in recent years. Targeted mining of deep-seabed minerals could have adverse effects on the associated ecosystems, but knowledge on the biological communities found there, their structure and functions is still limited. The focus of this study is to provide an overview on isopod crustaceans from the Clarion Clipperton Fracture Zone (CCFZ), an area well-known for its abundance of high-grade polymetallic nodules. Isopods generally comprise an important part of the macrofaunal communities of soft deep-sea sediments and indeed are one of the most dominant macrobenthic groups in the CCFZ. In this review, we have compiled all available data and information on isopod diversity and distribution in the CCFZ in a hybrid manner, which includes published data from the literature as well as the analysis of previously unpublished sources and newly collected data. Although isopods are one of the more prevalent and better-known groups of the CCFZ fauna, this study shows that it is still remarkably difficult to obtain a clear perception of isopod diversity and distribution, as well as the factors that could be responsible for the observed patterns. In many places, knowledge remains incomplete, which is largely due to the low sampling and taxonomic effort, non-standardised sample protocols and the limited taxonomic inter-calibration between studies. The latter is pivotal due to the high proportion of undescribed and presumably new species that typically occur there. An important starting point would therefore be to increase sampling effort and its spatial and temporal coverage in a standardised way, to intensify (integrative) taxonomic work as well as to facilitate sample and data exchange between scientists and contractors. These are fundamental requirements to improve our understanding of the biodiversity of isopods, but also of other faunal groups, in the CCFZ, before mining operations begin.

    Description: The Storegga Slide is the largest known exposed submarine landslide in the world, which triggered a tsunami that inundated the coasts of northern Europe ~8,150 years ago. Previous studies suggested the removal of 50–70 m of sediment from the northern slide scar segment, contributing half of the total slide volume of up to 3200 km³. However, new sediment echosounder profiles and sedimentological constraints show that most material within the northern Storegga slide scar had already failed ~20,000 years ago, at the end of the Last Glacial Maximum. We refer to this previously undetected slope failure as the Nyegga Slide. In our revised slope failure reconstruction, the Nyegga Slide removed more than 35 m of sediments that were previously attributed to the tsunamigenic Storegga Slide. This implies that large slope failures at the mid-Norwegian margin occur more frequently than previously thought, indicating a higher tsunami hazard for the North Atlantic.

    Description: For the first time, the processes controlling the variations of mixed layer temperature (MLT) and salinity (MLS) in the Banda Sea are quantified using data from a single Argo float in combination with satellite and reanalysis outputs from August 2017 to August 2019. This augments previous studies that utilized ocean model data only. We document the presence of a barrier layer and quantify the roles of air-sea heat and mass exchanges, horizontal advection, and vertical entrainment in the seasonal variability of MLT and MLS. We find that heat gains and losses at the air-sea interface are the main contributor to the warming and cooling of the MLT. Seasonal changes in MLS are driven by advection of low salinity water rather than freshwater fluxes from precipitation and evaporation. This is particularly the case during the late northwest and monsoon transition period from February to April when low salinity is advected eastward from the Java Sea into the Banda Sea.

    Description: A quantitative local analytical method with the application of inductively coupled plasma mass spectrometry with laser ablation (LA-ICP-MS) was tested at Vernadsky Institute for the determination of contents of trace elements (Cu, Zn, Co, Ni, Mn, Cr, Sc, V, Ca, Ti, Al, Y, and REE) in olivine. Olivine phenocrysts from volcanic rocks of various geological settings have been studied: island-arc basalts, mid-ocean ridge (MOR) basalts, and high-alkaline continental volcanic rocks. The contents of some elements (Ni, Co, Mn, Cr, Sc, and Zn) systematically vary during the evolution of the composition of olivine, and the concentration fields of these elements in olivine from different settings overlap one another. At the same time, the contents of some other elements (Ca, Al, Ti, V, and Cu) fundamentally differ in olivine from different geological settings. Copper content in olivine from oceanic tholeiites and highly alkaline continental volcanics is 1–3 ppm, which is systematically lower than copper content in olivine from island-arc basalts (3–9 ppm). The concentrations of vanadium in olivine in MOR basalts are higher than in island-arc and alkaline continental ones, which may be due to relatively more reduced crystallization conditions as more favorable for the incorporation of V3+ into the olivine structure. Variations in the distribution coefficients of trace elements between olivine and silicate melt (DOl/Melement) were determined for volcanic rocks from Kamchatka, the Bouvet Triple Junction, and Gaussberg volcano. It has been demonstrated that the unusually high values DOl/MNi of DOl/MNi = 50–150 previously identified for the lamproites of Gaussberg volcano indicate a mismatch between the composition of the quenched glass and the composition of the equilibrium melt for olivine phenocrysts. When using the bulk compositions of Gaussberg rocks, values of DOl/MNi = 11–21 were obtained, which correspond to experimental estimates for high-potassium rocks. The redox crystallization conditions of the studied rocks were estimated using several oxybarometers based on the distribution of vanadium between coexisting olivine and melt. These values were: ΔQFM= +0.6 to +1.5 for oceanic tholeiites of the Bouvet Triple Junction area, South Atlantic, and ΔQFM = +1.5 to +2.4 for Mutnovsky volcano, Kamchatka. Estimates of the redox crystallization conditions of the highly alkaline rocks of Gaussberg volcano significantly vary depending on which model is chosen: ΔQFM= +0.2 to +4.8, which may be due to the strong effect of K2O content in the melt involved in one of the models. The newly acquired analytical data confirmed the possibility of using contents of trace elements in olivine to characterize igneous systems from different geological settings and highlighted the need for additional experimental studies on the distribution of these elements between olivine and melt, especially in highly alkaline systems.

    Description: Excess nutrient supply by the rivers and the atmosphere are considered as the major causes for the persistently poor ecological status of the Baltic Sea. More than 97% of the Baltic Sea still suffers from eutrophication due to past and present inputs of nitrogen and phosphorus. One of the poorly quantified nutrient sources in the Baltic Sea is submarine groundwater discharge (SGD). Through seepage meter deployments and a radium mass balance model, a widespread occurrence of SGD along the coastline of Eckernförde Bay was detected. Mean SGD was 21.6 cm d −1 with a calculated freshwater fraction of 17%. Where SGD was detected, pore water sampled by a piezometer revealed a wide range of dissolved inorganic nitrogen (DIN: 0.05–1.722 µmol L −1 ) and phosphate (PO 4 3− : 0.03–70.5 µmol L −1 ) concentrations. Mean DIN and PO 4 3− concentrations in non-saline (salinity 〈 1) pore waters were 59 ± 68 µmol L −1 and 1.2 ± 1.9 µmol L −1 , respectively; whereas pore water with salinities 〉 1 revealed higher values, 113 ± 207 µmol L −1 and 6 ± 12 µmol L −1 for DIN and PO 4 3− , respectively. The nutrient concentrations along the salinity gradient do not suggest that land-derived groundwater is the definitive source of nutrients in the Baltic Sea. Still, SGD may contribute to a major autochthonous nutrient source, resulting from remineralization or dissolution processes of organic matter in the sediments. The DIN and PO 4 3− fluxes derived from SGD rates through seepage meters are 7.9 ± 9.2 mmol m −2 d −1 and 0.5 ± 0.4 mmol m −2 d −1 , lower by a factor of ~ 2 and ~ 5 when compared to the fluxes derived with the radium mass balance model (mean DIN: 19 ± 28 mmol m −2 d −1 ; mean PO 4 3− : 1.5 ± 2.7 mmol m −2 d −1 ). Assuming that these mean radium-based nutrient fluxes are representative for the coastline of Eckernförde Bay, we arrive at SGD-borne nutrient fluxes of about 1 t km −1 y −1 of nitrogen and 0.2 t km −1 y −1 of phosphorous. These fluxes are lower for DIN and in the same range for phosphorus as compared to the riverine nutrient supply (DIN: 6.3 t km −1 y −1 , P: 0.2 km −1 y −1 ) to the German Baltic Sea identifying SGD-borne nutrients as a secondary nutrient source to the Baltic Sea.

    Description: Planktonic Foraminifera are unique paleo-environmental indicators through their excellent fossil record in ocean sediments. Their distribution and diversity are affected by different environmental factors including anthropogenically forced ocean and climate change. Until now, historical changes in their distribution have not been fully assessed at the global scale. Here we present the FORCIS (Foraminifera Response to Climatic Stress) database on foraminiferal species diversity and distribution in the global ocean from 1910 until 2018 including published and unpublished data. The FORCIS database includes data collected using plankton tows, continuous plankton recorder, sediment traps and plankton pump, and contains similar to 22,000, similar to 157,000, similar to 9,000, similar to 400 subsamples, respectively (one single plankton aliquot collected within a depth range, time interval, size fraction range, at a single location) from each category. Our database provides a perspective of the distribution patterns of planktonic Foraminifera in the global ocean on large spatial (regional to basin scale, and at the vertical scale), and temporal (seasonal to interdecadal) scales over the past century.

    Description: Focused fluid flow through sub-seafloor pipes and chimneys, and their seafloor manifestations as pockmarks, are ubiquitous. However, the dynamics of flow localization and evolution of fluid escape structures remain poorly understood. Models based on geomechanical mechanisms like hydro-fracturing and porosity wave propagation offer some useful insights into fluid flow and escape dynamics, but face limitations in capturing features like mobilized granular matter, especially in the upper sediment layers where the link between fracture and pockmark is not always clear. Here, we propose a mathematical model based on the multiphase theory of porous media, where changes in subsurface and seafloor morphology are resolved through seepage-induced erosion, fluidization, transport, and re-deposition of granular material. Through simulation of an idealized scenario of gas escape from overpressured shallow gas reservoir, we demonstrate that our model can capture flow localization and formation of pipes, chimneys, and pockmarks. Our simulations show (1) formation of conical focused-flow conduits with a brecciated core and annular gas channels; (2) pockmarks of W and ring shapes; and (3) pulsed release of gas. Sediment erodibility and flow anisotropy control the morphology of focused fluid flow and escape structures, while permeability shows negligible impact. While the geological setting for this study is theoretical, we show that our results have real-world analogs.

    Description: Background: The widespread Indo-Pacific coral species Pocillopora acuta Lamarck, 1816 displays varying levels of asexual versus sexual reproduction, with strong repercussions on genetic diversity, connectivity and genetic structuring within and among populations. For many geographic regions, baseline information on genetic diversity is still lacking, particularly in the Andaman Sea. The region suffered a massive heat-induced bleaching event in 2010 with high coral cover loss of branching coral species such as P. acuta. A subsequent bleaching in 2016, however, revealed a mild bleaching response in pocilloporids compared to other coral taxa in the region, suggesting that rare, heat tolerant genotypes had been selected by the 2010 bleaching event. In order to test whether this potential ‘evolutionary rescue’ event has led to a low genetic diversity, we conducted a population genetic survey covering a total of nine different P. acuta populations (336 individuals) along a 50 km coastal stretch around Phuket Island, Thailand. We used six microsatellite markers to assess genotypic diversity and to determine the prevalent mode of reproduction (i.e. sexual or asexual recruitment). Results: In contrast to other Indian Ocean P. acuta populations, the majority of corals in this study adopted a sexual reproduction mode (75% across all populations). At the same time, substantial regional gene flow was observed around Phuket Island with strong genetic differentiation as indicated by three genetic clusters that were separated by only a few kilometers. Patterns of isolation by distance over 0.7 – 40 km suggest small-scale genetic barriers, such as changing currents throughout each monsoonal season, potentially contributing to locally restricted dispersal of P. acuta larvae. Conclusions: The occurrence of distinct genetic clusters within short coastal stretches suggests that the 2010 bleaching event has not led to extreme genetic impoverishment. While more in-depth genomic analyses are necessary to investigate changes in genetic diversity following extreme bleaching events, our results will help guide conservation efforts to maintain genetic diversity of a coral species that likely will be dominant in future, warmer Andaman Sea reefs.

    Description: Dissolved organic matter (DOM) occupies a huge and uncharted molecular space. Given its properties, DOM can be presented as a promising biotechnological resource. However, research into bioactivities of DOM is still in early stages. In this study, the biotechnological potential of terrestrial and marine DOM, its molecular composition and their relationships are investigated. Samples were screened for their in vitro antibacterial, antifungal, anticancer and antioxidant activities. Antibacterial activity was detected against Staphylococcus aureus in almost all DOM samples, with freshwater DOM showing the lowest IC50 values. Most samples also inhibited Staphylococcus epidermidis, and four DOM extracts showed up to fourfold higher potency than the reference drug. Antifungal activity was limited to only porewater DOM towards human dermatophyte Trichophyton rubrum. No significant in vitro anticancer activity was observed. Low antioxidant potential was exerted. The molecular characterization by FT-ICR MS allowed a broad compositional overview. Three main distinguished groups have been identified by PCoA analyses. Antibacterial activities are related to high aromaticity content and highly-unsaturated molecular formulae (O-poor). Antifungal effect is correlated with highly-unsaturated molecular formulae (O-rich). Antioxidant activity is positively related to the presence of double bonds and polyphenols. This study evidenced for the first time antibacterial and antifungal activity in DOM with potential applications in cosmeceutical, pharmaceutical and aquaculture industry. The lack of cytotoxicity and the almost unlimited presence of this organic material may open new avenues in future marine bioprospecting efforts.

    Description: Background: The microbiota of multicellular organisms undergoes considerable changes during host ontogeny but the general mechanisms that control community assembly and succession are poorly understood. Here, we use bacterial recolonization experiments in Nematostella vectensis as a model to understand general mechanisms determining bacterial establishment and succession. We compared the dynamic establishment of the microbiome on the germfree host and on inert silicone tubes. Results: Following the dynamic reconstruction of microbial communities on both substrates, we show that the initial colonization events are strongly influenced by the host but not by the silicone tube, while the subsequent bacteria-bacteria interactions are the main driver of bacterial succession. Interestingly, the recolonization pattern on adult hosts resembles the ontogenetic colonization succession. This process occurs independently of the bacterial composition of the inoculum and can be followed at the level of individual bacteria. To identify potential metabolic traits associated with initial colonization success and potential metabolic interactions among bacteria associated with bacterial succession, we reconstructed the metabolic networks of bacterial colonizers based on their genomes. These analyses revealed that bacterial metabolic capabilities reflect the recolonization pattern, and the degradation of chitin might be a selection factor during early recolonization of the animal. Concurrently, transcriptomic analyses revealed that Nematostella possesses two chitin synthase genes, one of which is upregulated during early recolonization. Conclusions: Our results show that early recolonization events are strongly controlled by the host while subsequent colonization depends on metabolic bacteria-bacteria interactions largely independent of host ontogeny.

    Description: The effect of anthropogenic climate change in the ocean is challenging to project because atmosphere-ocean general circulation models (AOGCMs) respond differently to forcing. This study focuses on changes in the Atlantic Meridional Overturning Circulation (AMOC), ocean heat content (Δ OHC), and the spatial pattern of ocean dynamic sea level (Δ ζ). We analyse experiments following the FAFMIP protocol, in which AOGCMs are forced at the ocean surface with standardised heat, freshwater and momentum flux perturbations, typical of those produced by doubling CO 2. Using two new heat-flux-forced experiments, we find that the AMOC weakening is mainly caused by and linearly related to the North Atlantic heat flux perturbation, and further weakened by a positive coupled heat flux feedback. The quantitative relationships are model-dependent, but few models show significant AMOC change due to freshwater or momentum forcing, or to heat flux forcing outside the North Atlantic. AMOC decline causes warming at the South Atlantic-Southern Ocean interface. It does not strongly affect the global-mean vertical distribution of Δ OHC, which is dominated by the Southern Ocean. AMOC decline strongly affects Δ ζ in the North Atlantic, with smaller effects in the Southern Ocean and North Pacific. The ensemble-mean Δ ζ and Δ OHC patterns are mostly attributable to the heat added by the flux perturbation, with smaller effects from ocean heat and salinity redistribution. The ensemble spread, on the other hand, is largely due to redistribution, with pronounced disagreement among the AOGCMs.

    Description: Food web research provides essential insights into ecosystem functioning, but practical applications in ecosystem-based management are hampered by a current lack of knowledge synthesis. To address this gap, we provide the first systematic review of ecological studies applying stable isotope analysis, a pivotal method in food web research, in the heavily anthropogenically impacted Baltic Sea macro-region. We identified a thriving research field, with 164 publications advancing a broad range of fundamental and applied research topics, but also found structural shortcomings limiting ecosystem-level understanding. We argue that enhanced collaboration and integration, including the systematic submission of Baltic Sea primary datasets to stable isotope databases, would help to overcome many of the current shortcomings, unify the scattered knowledge base, and promote future food web research and science-based resource management. The effort undertaken here demonstrates the value of macro-regional synthesis, in enhancing access to existing data and supporting strategic planning of research agendas.

    Description: Understanding the drivers behind fluctuations in fish populations remains a key objective in fishery science. Our predictive capacity to explain these fluctuations is still relatively low, due to the amalgam of interacting bottom-up and top-down factors, which vary across time and space among and within populations. Gaining a mechanistic understanding of these recruitment drivers requires a holistic approach, combining field, experimental and modelling efforts. Here, we use the Western Baltic Spring-Spawning (WBSS) herring (Clupea harengus) to exemplify the power of this holistic approach and the high complexity of the recruitment drivers (and their interactions). Since the early 2000s, low recruitment levels have promoted intense research on this stock. Our literature synthesis suggests that the major drivers are habitat compression of the spawning beds (due to eutrophication and coastal modification mainly) and warming, which indirectly leads to changes in spawning phenology, prey abundance and predation pressure. Other factors include increased intensity of extreme climate events and new predators in the system. Four main knowledge gaps were identified related to life-cycle migration and habitat use, population structure and demographics, life-stage specific impact of multi-stressors, and predator–prey interactions. Specific research topics within these areas are proposed, as well as the priority to support a sustainable management of the stock. Given that the Baltic Sea is severely impacted by warming, eutrophication and altered precipitation, WBSS herring could be a harbinger of potential effects of changing environmental drivers to the recruitment of small pelagic fishes in other coastal areas in the world.

    Description: Hydroacoustic surveys at the accretionary wedge southwest of Taiwan reveal a confined active hydrocarbon seepage area of ~ 49,000 m 2 in ~ 1350 m water depth on the northern crest of the Four-Way Closure Ridge, which we call Yam Seep. In this study, multibeam and side-scan sonar data acquired during surveys with an autonomous underwater vehicle during an expedition with R/V Ocean Researcher I in 2017 showed that the area is characterized by rough topography and high seafloor backscatter. Seafloor observations with a video sled and sediment sampling with gravity corers and the MeBo seafloor drill rig during an expedition with R/V SONNE in 2018 revealed that the area is almost entirely covered by intensely fractured methane-derived carbonates, which indicate that seepage has been ongoing for thousands of years. Hydroacoustic anomalies (‘flares’) in the water column indicated the presence of several gas bubble emission sites mostly at the center and eastern flank of the area in 2019. Drilling through massive carbonates in the northwestern part of Yam Seep induced free gas escape from a depth of ~ 5.1 m. This suggests the presence of gas hydrates in the subsurface as the seep area is located well within the gas hydrate stability zone. The inter-disciplinary investigations of the Yam Seep demonstrate that upward migration of light hydrocarbons and seafloor discharge has a considerable influence on the seabed properties.

    Description: Interactions between volcanoes and glaciers provide insight to the evolution of a volcanic edifice and may be an indicator for renewed volcanic activity. At Mount St. Helens, Crater Glacier, which has formed in the volcanic crater after the eruption in 1980, is one of the world’s last expanding glaciers and provides a unique opportunity to characterize the evolution of a glacier expanding onto an area of significant thermal flux. We combine photographic documentation and glaciovolcanic cave surveys with remote sensing data from Google Earth, UAS, and LiDAR to analyze the present state of Crater Glacier and reconstruct its development since the emplacement of the 2004–2008 lava dome. Our results show that snow accumulation has caused Crater Glacier to grow from 2009 to 2019 by approximately 13.8 × 106 m3, during which time the glacier toe advanced by several hundred meters. The glacier-dome interface shift toward higher elevations against the 2004–2008 lava dome and subsequent encroachment onto thermally active areas led to glacier modification via extensive subglacial cave system formation. Analysis of subglacial tephra layers revealed the existence of juvenile material from the 2004–2008 eruption cycle, providing insights about glacier subsidence of ~ 40 m since 2004/2005 in spite of net growth. Although the lava dome is cooling, the glacier-dome interface seems to have become increasingly stable in the past few years. Our results suggest that glacier development in the accumulation area adjacent to the dome is now being affected by the thermal characteristics of the lava dome itself, making monitoring internal glacier development via tracking glaciovolcanic cave expansion a potentially important volcano monitoring tool. Zusammenfassung Die Interaktionen von Vulkanen und Gletschern tragen häufig zum Verständnis über die Entwicklung eines vulkanischen Systems bei und können als Indikator für wiederkehrende vulkanische Aktivität dienen. Crater Glacier, der nach der Eruption 1980 im Krater des Mount St. Helens entstanden ist, ist einer der letzten wachsenden Gletscher weltweit und bietet somit eine einmalige Chance, die Entwicklung eines Gletschers in Verbindung mit erheblichen Wärmeflüssen zu charakterisieren. Neben einer fotografischen Dokumentation des Gletschers machen wir uns die Kartierung vulkanischer Gletscherhöhlen zu Nutze. Diese kombinieren wir mit Fernerkundungsdaten von Google Earth sowie Drohnen- und LiDAR-Daten, um den aktuellen Zustand des Gletschers zu charakterisieren und seine Entwicklung seit dem letzten Lavadomwachstum zwischen 2004 und 2008 zu rekonstruieren. Unsere Ergebnisse zeigen, dass die ausreichende Akkumulation von Schnee zum Wachstum des Gletschers mit einem Massenzuwachs von ca. 13,8 x 106 m3 zwischen 2009 und 2019 geführt hat. Neben dem Voranschreiten der Gletscherzunge um mehrere hundert Meter hat sich das Wachstum ebenfalls rund um den neuen Lavadom bemerkbar gemacht. Durch die Verschiebung der Kontaktzone von Gletscher und Lavadom hin zu höheren Bereichen des Doms und der damit verbundenen Interaktion zwischen Gletscher und geothermaler Aktivität ist es zu einer deutlichen Veränderung des Gletschers durch die Ausbildung subglazialer Höhlensysteme gekommen. Analysen von im Gletscher eingebetteten Tephraschichten, die vermutlich der letzten Aktivität zwischen 2004 und 2008 zuzuordnen sind, deuten trotz des allgemeinen Wachstums auf eine Setzung des Gletschers um etwa 40 m seit 2004/05 hin. Obwohl der Lavadom an Hitze verliert, scheint die Kontaktzone von Gletscher und Dom in den letzten Jahren zunehmend konstant geworden zu sein. Unsere Ergebnisse deuten darauf hin, dass der Gletscher in diesem Bereich derzeit vor allem durch die thermalen Eigenschaften des Lavadoms beeinflusst wird. Dadurch kommt dem Monitoring interner Gletscherstrukturen mittels Beobachtung vulkanischer Gletscherhöhlen eine potenziell wichtige Bedeutung bei der Vulkanüberwachung zu.

    Description: Military field exercises are characterised by high volumes of exercise and prolonged periods of load carriage. Exercise can decrease circulating serum calcium and increase parathyroid hormone and bone resorption. These disturbances to calcium and bone metabolism can be attenuated with calcium supplementation immediately before exercise. This randomised crossover trial will investigate the effect of calcium supplementation on calcium and bone metabolism, and bone mineral balance, during load carriage exercise in women. Methods Thirty women (eumenorrheic or using the combined oral contraceptive pill, intrauterine system, or intrauterine device) will complete two experimental testing sessions either with, or without, a calcium supplement (1000 mg). Each experimental testing session will involve one 120 min session of load carriage exercise carrying 20 kg. Venous blood samples will be taken and analysed for biochemical markers of bone resorption and formation, calcium metabolism, and endocrine function. Urine will be collected pre- and post-load carriage to measure calcium isotopes for the calculation of bone calcium balance. Discussion The results from this study will help identify whether supplementing women with calcium during load carriage is protective of bone and calcium homeostasis.

    Description: Since the discovery of the first oncaeid copepod described by Philippi in 1843 as Oncaea venusta, great progress has been achieved regarding the morphological/descriptive taxonomy of the microcopepod family Oncaeidae, occurring in all great oceans and all depth layers of the ocean. The species diversity of this family is still underestimated and the ecological role of oncaeids within the marine ecosystem is not yet well understood, but the life strategy appears to be fundamentally different from most other pelagic microcopepod families. The present paper aims at a comprehensive review of the current state of knowledge of this microcopepod family, including taxonomic and phylogenetic issues, questions of species identification, specific morphological and molecular genetic characteristics, information on regional and vertical distribution and abundance, motion behaviour, feeding and food relationships, reproduction aspects, biomass and elemental composition, respiration and metabolic rates. Relevant open questions are highlighted, and examples are given of shortcomings and high uncertainties in results of current attempts to include oncaeid copepods in various aspects of global marine ecosystem studies. It is concluded that continued support of taxonomic research is required for Oncaeidae and other small copepod species, based on an integrated approach of morphological and molecular genetic methods and user-friendly regional identification keys, to allow an adequate consideration of oncaeids in advanced ecological studies and to achieve a better understanding of the ecological role of this abundant microcopepod family in marine ecosystems.

    Description: Temperate fisheries grounds are exposed to compound effects of jellyfish proliferations and fishing pressure, which affect local fisheries, cause economic losses, and threaten seafood supply. Here, we quantify the interlink between climate variability and jellyfish blooms and their impact on the Japanese anchovy (Engraulis japonicus), in the Korean coastal waters. We used a bioclimate dataset (2010–2019) that includes quantitative information of two major bloom-former species, Aurelia coerulea and Nemopilema nomurai, in the Korean Peninsula. We show that climate phenomena governing East Asia regions explain circa half of jellyfish variability. In turn, jellyfish blooms have a significant negative effect on anchovy interannual changes (r = -0.47, P 〈 0.01), which varies along with the bloom magnitude. Our results indicate that the intensity of jellyfish blooms, more than their duration, has a predominant effect on anchovy and coastal fisheries production. We also suggest the possibility of using climate signals for assessing and eventually predicting, interannual abundance changes of jellyfish in the Korean Peninsula. These results stress the challenge posed by jellyfish blooms to the provisioning of ecosystem services via their influence on marine harvested fish and further highlight the need for their integration into ecosystem-based management.

    Description: Removal of atmospheric carbon dioxide is being considered a suitable option for reducing the recent global rise in atmospheric temperature. The impact of the removal on some climate parameters—near-surface air temperature (TAS), maximum near-surface air temperature (TASMAX), minimum near-surface air temperature (TASMIN) and surface temperature (TS) over West Africa was assessed in this paper. We used CNRM-ESM1-C1 model simulation output consisting of 1%yr−1 CO2 removal from the atmosphere which was compared with CRU observational dataset. Four climatological periods 1990–2019 (reference period), 2040–2069, 2070–2099 and 2100–2129 were considered, and hence the impacts levels in each of the two West African regions, Sahel and Guinea, were estimated in each period with respect to the reference period. The comparison with CRU demonstrated that CNRM-ESM1-C1 model captured temperature variations within major locations in Mauritania, Mali, Niger, Burkina Faso and Senegal with an indication of an underestimation of temperature at locations above 18° N. The value of each parameter was projected to decrease progressively the periods and much impacts were also projected in the last period for the two regions. Time of retreat to 2 °C reduction target is projected a decade before the year 2100 and will occur earlier with greater impact in the Guinea region than in Sahel region. The root mean square deviation of each ensemble member was found at RMSD 〈 0.5 with respect to the model ensemble mean per parameter, although RMSD 〉 0.5 was found with GFDL-ESM4 model for TAS and TS.

    Description: The conventional view of spawning in iteroparous bony fish, i.e., the “reproductive drain hypothesis,” is based on the observation that somatic growth (in length) slows down noticeably at approximately the time fish attain maturity, and hence the assumption is made that investment in gonadal development slows down growth. However, when this is translated as growth in weight, the weight at first maturity (or puberty) is usually smaller than the weight at which growth rate is highest, i.e., weight growth accelerates after first maturity. We solve this conundrum, with some emphasis on female cod (Gadus morhua), by proposing the hypothesis that the substantial loss of body mass experienced by fish as a result of spawning is quickly compensated for by increased somatic growth after the spawning period, notably because of the increase in food conversion efficiency resulting from a sudden loss of body weight, which necessarily leads to a large increase in relative oxygen supply via the gills. This is consistent with the argument developed elsewhere that declining relative oxygen supply by the gills, whose surface area cannot keep up with increasing body weight, is the reason for growth rate declining with weight in adult fish.

    Description: This paper presents numerous new data on the geochemical composition of olivine, clinopyroxene, and leucite phenocrysts, as well as spinel inclusions in olivine and quench glass from lamproites of Gaussberg volcano (East Antarctica). Most of the olivine phenocrysts in the Gaussberg lamproites are high Mg varieties (Fo89–91) with elevated Ni contents (up to 4900 ppm) and high Ni/Co ratios. According to data of about 320 clinopyroxene analyses, two groups of diopsidic phenocrysts have been established. Group I consists mainly of high-Mg varieties (Mg#〉80), while group II clinopyroxenes are less magnesian (Mg# 52–80). The main difference between the clinopyroxenes of the two groups is the elevated contents of Al2O3, FeO and reduced TiO2, Cr2O3, and NiO in the compositions of group II compared to group I, as well as different contents of trace elements, which may reflect their crystallization from different types of primary melts. According to the study of ~550 grains of leucite phenocrysts in the Gaussberg lamproites, it was shown that they correspond to the ideal stoichiometry of leucite K[AlSi2O6] and are enriched in Na2O (0.05–0.35 wt %), but depleted in K2O (19.9–20.9 wt %) compared to leucites from lamproites of other provinces. The BaO content reaches 0.3 wt %, SrO –0.04 wt %. The iron content in most leucite phenocrysts varies within 0.7–1.2 wt % Fe2O3, but some grains have the low Fe2O3 contents (〈0.5 wt %). In leucite microlites of the groundmass and rims of phenocrysts, the Fe2O3 content can reach 2.4 wt %, which may indicate more oxidized conditions at lava eruption. Based on the study of natural samples, existing experimental data and numerical models, the order and conditions of crystallization of the Gaussberg lamproites were obtained. Crystallization proceeded in the following order: chromian spinel → chromian spinel + olivine → olivine + leucite (± chromian spinel) → olivine + leucite + clinopyroxene (± chromian spinel). The near-liquidus assemblage represented by high-Mg olivine phenocrysts with inclusions of Cr-spinel was formed in the temperature range from 1180 to 1250°C. Further crystallization of the melt with the formation of an association of olivine+leucite+clinopyroxene phenocrysts could occur at pressures below 2 GPa and temperatures of 1070–1180°C, corresponding to the presence of water in the magmatic system. Estimates of the redox conditions of crystallization of lamproites obtained using different oxybarometers vary in a wide range from QFM-0.5 to QFM+2.3. The elevated Ni contents in liquidus olivines of Gaussberg indicate the high nickel contents in the source. It is shown that the formation of ultra-alkaline magmas in the Gaussberg volcano area is likely related to melting of the continental lithosphere, which was heterogeneous and included both the peridotite mantle and hydrous pyroxenite fragments.

    Description: A.G. Bain (1797–1864) was probably the first to describe the deposits of the Permo-Carboniferous glaciation of South Africa in 1844, but still attributed their formation to a volcanic origin. It was not until P.C. Sutherland (1822–1908) in 1868 and 1870 that the series was recognised as a glacial formation. J. E. Dunn (1844–1937) named this deposit the Dwyka Series or Dwyka Conglomerate after the Dwyka River near Prince Albert in South Africa in 1886. This series contains scratched boulders and varved sediments, and the basement is characterised by rounded boulders and striated surfaces as evidence of glaciation.

    Description: In this study, we present a new 87 Sr/ 86 Sr isoscape map of Central and NE Germany. This area is characterized by an alternation of sedimentary basins and mountainous regions with a very variable lithology. Since lithology and rock age have a major impact on the isotopic composition of biologically available strontium, Central and NE Germany should reveal highly variable 87 Sr/ 86 Sr ratios. From lithological characteristics, particularly high ratios are expected in the mountainous regions of the Erzgebirge/Fichtelgebirge and the Harz Mountains. In contrast to these predictions, published 87 Sr/ 86 Sr isoscape maps of Central and NE Germany record rather uniform and low 87 Sr/ 86 Sr ratios. From this observation, we suspected that existing isoscape maps might be computed from an insufficient database, with mountainous regions being underrepresented. Our goal was to gather 87 Sr/ 86 Sr baselines for each major lithology of Central and NE Germany and to produce an accurate isoscape map of Central and NE Germany. In the first step, we evaluated the suitability of stream water and groundwater as a proxy for biologically available strontium. In a selected watershed, we present mixing relationships and a stream network model. We show that groundwater is prone to very local geologic and anthropogenic influences and should thus be avoided. Instead, we focussed our further sampling on stream water. Altogether, we used 119 new measurements of groundwater and stream water and a set of 23 auxiliary variables as a database for our new isoscape map of Central and NE Germany. Due to a sampling strategy that focussed on covering each major lithology, our measurements and the final isoscape map show a clear contrast between sedimentary basins and mountainous regions. For regions that have been sufficiently sampled, a direct comparison of the isoscape map with published and new data shows good agreement. Although Central and NE Germany were part of published isoscape maps, our new map is the first that predicts 87 Sr/ 86 Sr ratios in mountainous regions with high accuracy.

    Description: This Open Access book on Ocean Governance examines sustainability challenges facing our oceans today. The book is organized into three sections: knowledge systems, policy foundations and thematic analyses. The knowledge produced in the book was catalyzed by the scientific outcomes within the European-funded Cooperation in Science and Technology (COST) network “Ocean Governance for Sustainability – Challenges, Options and the Role of Science”. This network brings together scientists, policy-makers and civil society representatives from 28 nation states to cooperate on ocean governance research. This book offers a compilation of new research material including focused case studies, broad policy syntheses and reflective chapters on the history and current status of knowledge production systems on ocean governance. New research material is presented, although some chapters draw on secondary sources. The book starts with synthetic review chapters from the editors, outlining past and present knowledge systems, addressing how and why ocean governance for sustainability is where it currently stands with critical reflections on existing narratives, path dependencies and colonialist histories. This is followed by chapters addressing, synthesizing and analyzing different legal and policy frameworks for ocean governance both regionally and internationally. At the core of the book are the thematic analyses, which provide focused case studies with detailed contextual information in support of different ocean governance challenges and sustainability pathways around the world. The book concludes with a chapter explicitly targeting students, researchers and policy-makers with key take-away messages compiled by the editors.

    Description: Over one hundred years of vigorous progress in tropical cyclone (TC) research, the genesis of the cyclone (hereafter, tropical cyclogenesis) is remarkable as a doubtful subject. Furthermore, predicting tropical cyclogenesis, particularly in the lesser latitude, remains a significant challenge. Therefore, understanding the complex interactions in developing tropical cyclogenesis over the region is vital to improving tropical cyclogenesis forecasting. Hence, the Indonesia Maritime Continent is a tropical cyclone-free region due to decreasing the Coriolis effect. However, Seroja TC hit Flores (8.6° S, 120° E), east Nusa Tenggara, Indonesia, on 4 April 2021, and was recorded as the first TC that occurred over the mainland, which brought a catastrophic disaster in the region. This study investigated the tropical cyclogenesis of Seroja by using observational and numerical studies. The results indicate that a marine heatwave and double vortices were favorable conditions that produced preconditions for developing tropical cyclogenesis over the Maluku Sea. Thus, tropical cyclogenesis is formed by the breakdown of the intertropical convergence zone (ITCZ) associated with synoptic-scale wave train driven under the interaction of the Madden Julian oscillation (MJO) and equatorial Rossby waves. Moreover, our finding suggested that an extensive background cyclonic vorticity under the cold pool mechanisms is responsible for maintaining tropical cyclogenesis into a persistent Seroja TC.

    Description: The Clarion Clipperton Fracture Zone (CCZ) is an abyssal region in the north-east Pacific that is currently being explored for metal-rich polymetallic nodules, but also harbors a highly diverse megabenthic community. This community is influenced by multiple environmental gradients including bathymetric structures as well as differences in habitat and food availability. This study focuses on the benthic megafauna investigated in an exploration area positioned in the very east of the CCZ, which exhibits the lowest water depths (mean: 4200 m) and the highest flux of particulate organic carbon (POC) of the CCZ. Case studies using seafloor images for the detection of megafauna have revealed differences between seamounts and abyssal hills compared to nodule fields, as well as differences in the community composition between areas with and without nodule coverage and rock outcrop. Extrapolations suggest a richness of more than 300 morphotypes in the study area, including multiple invertebrate groups such as corals, sponges, echinoderms, and crustaceans as well as fish. Focusing on sampled specimens, diversities of Ophiuroidea, Porifera, and Bryozoa are high and more species are likely to be discovered in the study area. This also applies for the taxon Ophiuroidea, which is among the taxa investigated in the greatest detail so far. In the context of deep-sea mining, megafauna has been in the focus of a variety of environmental studies including baseline analyses, disturbance experiments, and/or testing of mining components or systems. These studies identify and address key factors responsible for the observed natural and impacted distribution patterns and thereby help to constrain expected anthropogenic impacts to the deep-sea environment in the context of deep-sea mining. Specifically in the area of focus of this study, 10 years of megafauna analyses have shown that the biodiversity in the selected preservation reference zone (PRZ) is not as similar to that of the impact reference zone (IRZ) as originally hypothesized based mainly on geological parameters. We suggest that recent area-wide habitat classifications and faunal mapping exercises (e.g., Uhlenkott et al. 2020, 2022) are used to designate a new PRZ that is more similar to the IRZ to meet its purpose, but that the current PRZ is maintained for scientific and conservation purposes.

    Description: Understanding how the salt marsh vegetation will evolve under future climate conditions is essential for predicting the role of marsh ecosystem services in a warmer climate with higher CO 2 -concentrations. In a mesocosm experiment in the northern Wadden Sea, the impact of increased temperature (+ 3 °C) and CO 2 (800 ppm) on salt marsh vegetation was investigated, assessing biomass production in the pioneer zone and low marsh. The pioneer zone, which was dominated by Spartina anglica and exposed to natural tidal inundations , demonstrated a differentiated response between belowground and aboveground biomass. Aboveground biomass increased in response to enhanced CO 2 availability, and belowground biomass increased in response to raised temperatures. Other plant species accounted for less than 18% of the aboveground biomass, and their biomass was suppressed under high CO 2 availability. Increased biomass by Spartina anglica may improve resilience toward sea level rise. Hence, the pioneer zone is expected to maintain its coastal protection and blue carbon storage capacity under future climate conditions. The low marsh, which was dominated by Elymus athericus , was exposed to higher than usual tidal inundations and resembled a scenario with increased sea level. The low marsh showed no response in biomass to increased CO 2 or temperature, which may be due to the increased flooding. The positive response of Spartina anglica (C 4 plant) and the lack of response in Elymus athericus (C 3 plant) counter the notion that C 3 plants are more productive under future climate conditions and demonstrate that C 4 plants can also thrive in future salt marshes.

    Description: Background: Biological invasions threaten the functioning of ecosystems, biodiversity, and human well-being by degrading ecosystem services and eliciting massive economic costs. The European Union has historically been a hub for cultural development and global trade, and thus, has extensive opportunities for the introduction and spread of alien species. While reported costs of biological invasions to some member states have been recently assessed, ongoing knowledge gaps in taxonomic and spatio-temporal data suggest that these costs were considerably underestimated. Results: We used the latest available cost data in InvaCost (v4.1)—the most comprehensive database on the costs of biological invasions—to assess the magnitude of this underestimation within the European Union via projections of current and future invasion costs. We used macroeconomic scaling and temporal modelling approaches to project available cost information over gaps in taxa, space, and time, thereby producing a more complete estimate for the European Union economy. We identified that only 259 out of 13,331 (~ 1%) known invasive alien species have reported costs in the European Union. Using a conservative subset of highly reliable, observed, country-level cost entries from 49 species (totalling US$4.7 billion; 2017 value), combined with the establishment data of alien species within European Union member states, we projected unreported cost data for all member states. Conclusions: Our corrected estimate of observed costs was potentially 501% higher (US$28.0 billion) than currently recorded. Using future projections of current estimates, we also identified a substantial increase in costs and costly species (US$148.2 billion) by 2040. We urge that cost reporting be improved to clarify the economic impacts of greatest concern, concomitant with coordinated international action to prevent and mitigate the impacts of invasive alien species in the European Union and globally.

    Description: Ocean deoxygenation and expansion and intensification of hypoxia in the ocean are a major, growing threat to marine ecosystems. Measures currently used to protect marine biodiversity (e.g., marine protected areas) are ineffective in countering this threat. Here, we highlight the example of the Gulf of St. Lawrence in eastern Canada, where oxygen loss is not only due to eutrophication (which can be mitigated by nutrient controls) but also is a consequence of ocean circulation change and warming. Climate-related loss of oxygen will be an increasingly widespread source of risk to marine biodiversity over this century. Again using the Gulf of St. Lawrence as an example, we show that production of oxygen by the green hydrogen industry can be comparable to the loss rate of dissolved oxygen on large spatial scales, offering new possibilities for mitigation. However, this mitigation approach has rarely been considered for marine environments to date. Given confluence of increasing risk to marine ecosystems from oxygen loss and rapid emergence, worldwide, of industrial sources of pure oxygen, which are likely to be located in coastal regions, we believe this option will be proposed increasingly in coming years, including by the private sector. We argue that it is urgent for ocean scientists, engineers, and policymakers to recognize and address this emerging potential. A coordinated research effort should be established immediately in order to harness the potential of the green hydrogen industry to mitigate major impacts of climate change on marine biodiversity, and avoid any unintended negative consequences.

    Description: Two atmospheric feedbacks play an important role in the dynamics of the El Nino/Southern Oscillation (ENSO), namely the amplifying zonal wind feedback and the damping heat flux feedback. Here we investigate how and why both feedbacks change under global warming in climate models participating in the 5th and 6th phase of the Coupled Model Intercomparison Project (CMIP5 and CMIP6) under the business-as-usual scenario (RCP8.5 and SSP5-8.5, respectively). The amplifying zonal wind feedback over the western equatorial Pacific (WEP) becomes significantly stronger in two third of the models, on average by 12 +/- 7% in these models. The heat flux damping feedback over the eastern and central equatorial Pacific (EEP and CEP, respectively) increases as well in nearly all models, with the damping effect increasing on average by 18 +/- 11%. The simultaneous strengthening of the two feedbacks can be explained by the stronger warming in the EEP relative to the WEP and the off-equatorial regions, which shifts the rising branch of the Pacific Walker Circulation to the east and increases the mean convection over the CEP. This in turn leads to a stronger vertical wind response during ENSO events over the CEP that strengthens both atmospheric feedbacks. We separate the climate models into sub-ensembles with STRONG and WEAK ENSO atmospheric feedbacks, as 2/3 of the models underestimate both feedbacks under present-day conditions by more than 40%, causing an error compensation in the ENSO dynamics. The biased mean state in WEAK in 20C constrains the ENSO atmospheric feedback projection in 21C, as the models of the WEAK sub-ensemble also have weaker ENSO atmospheric feedbacks in 21C. Further, due to the more realistic dynamics and teleconnections, we postulate that one should have more confidence in the ENSO predictions with models belonging to the STRONG sub-ensemble. Finally, we analyze the relation between ENSO amplitude change and ENSO atmospheric feedback change. We find that models simulating an eastward shift of the zonal wind feedback and increasing precipitation over the EEP during Eastern Pacific El Nino events tend to predict a larger ENSO amplitude in response to global warming.

    Description: In recent decades, Arctic summer sea ice extent (SIE) has shown a rapid decline overlaid with large interannual variations, both of which are influenced by geopotential height anomalies over Greenland (GL-high) and the central Arctic (CA-high). In this study, we find that SIE along coastal Siberia (Sib-SIE) and Alaska (Ala-SIE) accounts for about 65% and 21% of the Arctic SIE interannual variability, respectively. Variability in Ala-SIE is related to the GL-high, whereas variability in Sib-SIE is related to the CA-high. A decreased Ala-SIE is associated with decreased cloud cover and increased easterly winds along the Alaskan coast, promoting ice-albedo feedback. A decreased Sib-SIE is associated with a significant increase in water vapor and downward longwave radiation (DLR) along the Siberian coast. The years 2012 and 2020 with minimum recorded ASIE are used as examples. Compared to climatology, summer 2012 is characterized by a significantly enhanced GL-high with major sea ice loss along the Alaskan coast, while summer 2020 is characterized by an enhanced CA-high with sea ice loss focused along the Siberian coast. In 2012, the lack of cloud cover along the Alaskan coast contributed to an increase in incoming solar radiation, amplifying ice-albedo feedback there; while in 2020 the opposite occurs with an increase in cloud cover along the Alaskan coast, resulting in a slight increase in sea ice there. Along the Siberian coast, increased DLR in 2020 plays a dominant role in sea ice loss and increased cloud cover and water vapor both contribute to the increased DLR.

    Description: The paper presents petrographic, mineralogical, and geochemical data on dunites, pyroxenites, peridotites, and gabbroids of the Kamchatsky Mys ophiolite. These data were acquired to distinguish cogenetic assemblages of igneous rocks, gain an insight into their geodynamic settings, and test various criteria of genetic links between the different magmatic rocks of ophiolites. The ultramafic and mafic rocks are shown to belong to two series, which differ in the compositions of the primary minerals, bulk rocks, and estimated trapped melts. The rocks of these series are found out to have been produced by geochemically different melts in different geodynamic settings, and during different episodes of mantle magmatism. The rocks of the high-Ti series (gabbro of the Olenegorsk massif, dunite and melanogabbro xenoliths in them, and vein gabbro in these xenoliths) crystallized from N-MORB melts in an oceanic spreading center. The rocks of the low-Ti series (dunite, pyroxenite, and gabbro veins in the residual spinel peridotites of the Mount Soldatskaya massif, as well as pyroxenite, peridotite, and gabbro alluvium and diluvium in the central and western parts of the peninsula) crystallized from water-rich boninite melts in relation to initial subduction magmatism. Taken into account the absence of boninite lavas from the Kamchatsky Mys ophiolite, the plutonic ultramafic rocks (including the rocks of the veins) might be the only evidence of subduction boninitic magmatism in the ophiolites. It was demonstrated that conclusions about the geodynamic settings of plutonic ultramafic and mafic rocks and recognition of cogenetic relations of these rocks with spatially associated basalts are more reliable when derived from the compositions of the trapped melts, which are estimated from their bulk geochemistry and primary mineral compositions, than when they are based on the mineral compositions only.

    Description: Kharchinsky and Zarechny volcanoes and the Kharchinsky Lake zone of monogenic cones are unique eruptive centers of magnesian lavas located above the northern margin of the Pacific plate subducting beneath Kamchatka. This paper presents new geochemical data on the composition of rocks (55 samples) and minerals (over 900 analyses of olivine, pyroxenes, amphibole, and plagioclase) of these centers analyzed by XRF and LA-ICP-MS (rocks) and electron microprobe (minerals). Most of the studied rocks are magnesian (Mg# = 60–75 mol %) medium-K basalts and basaltic andesites. Moderate-magnesian (Mg# = 52–59 mol %) basaltic andesites are present among the monogenic cones of Kharchinsky Lake. The rare rock varieties include the high-K basalts–basaltic andesites of dikes in the center of Kharchinsky volcano and the magnesian andesites (Mg# = 58–61 mol %) of the extrusions of Zarechnу volcano. The distribution of trace-element contents in these samples demonstrates enrichment in large-ion lithophile elements and light REEs at depletion in high field strength elements and heavy REEs, as is typical of arc rocks. The high-K basalts and basaltic andesites show anomalous enrichment in Ba (〉1000 ppm), Th (〉3.8 ppm), U (〉1.8 ppm), Sr (〉 800 ppm, Sr/Y 〉 50), and light REE (La 〉 20 ppm), and their compositions are close to those of low-Si adakites. The basalts and basaltic andesites contain phenocrysts of high-Mg olivine (up to Fo92.6) and clinopyroxene (Mg # up to 91 mol %). The rocks show petrographic and geochemical evidence of fractional crystallization, along with the processes of mineral accumulation and magma mixing. Some of the olivine phenocrysts show high NiO contents (up to 5000 ppm) and an elevated Fe/Mn ratio (up to 80), which were interpreted as evidence of the participation of a pyroxenite source in the magma generation processes. The use of the Ca/Fe and Ni/Mg ratios allowed us to distinguish the composition fields and evolution trends of olivine associated with different sources: peridotite and pyroxenite, which were formed by a reaction between mantle-wedge peridotites and high-Si melts of the subducted oceanic crust. The new data are consistent with other lines of evidence of melting of the subducted Pacific plate edge beneath the northern part of the Central Kamchatka Depression at the Kurile–Kamchatka and Aleutian subduction zone junction and testify to a significant heterogeneity of the mantle in this area.

    Description: The three-dimensional (3D) structure of habitat-forming corals has profound impacts on reef ecosystem processes. Elucidating coral structural responses to the environment is therefore crucial to understand changes in these ecosystems. However, little is known of how environmental factors shape coral structure in deep and dark waters, where cold-water coral (CWC) reefs thrive. Here, we attempt to infer the influence of current flow on CWC framework architecture, using 3D scanning to quantify colony shape traits (volume compactness and surface complexity) in the reef-building CWC Desmophyllum pertusum from adjacent fjord and offshore habitats with contrasting flow regimes. We find substantial architectural variability both between and within habitats. We show that corals are generally more compact in the fjord habitat, reflecting the prevailing higher current speeds, although differences in volume compactness between fjord and offshore corals are more subtle when comparing the fjord with the more exposed side of the offshore setting, probably due to locally intensified currents. Conversely, we observe no clear disparity in coral surface complexity between habitats (despite its positive correlation with volume compactness), suggesting it is not affected by current speed. Unlike volume compactness, surface complexity is similarly variable within a single colony as it is between colonies within the same habitat or between habitats and is therefore perhaps more dependent than volume compactness on microenvironmental conditions. These findings suggest a highly plastic, trait-specific and functionally relevant structural response of CWCs to current flow and underscore the importance of multiple concurrent sources of hydrodynamic forcing on CWC growth.

    Description: Squid play a major role in the Southern Ocean food web. However, their age and growth remain poorly studied. Here, using upper and lower beaks of Moroteuthopsis longimana collected from the diet of Dissostichus mawsoni from Pacific and Atlantic sectors of the Southern Ocean, we studied: (1) Feasibility of using beaks collected from predators’ stomachs to study the age of Southern Ocean oceanic squid; and (2) Age estimation and growth patterns of M. longimana. The rostrum sagittal section (RSS) of both beaks had micro-increments, with the lower beak being the best to observe and count a readable sequence of increments to estimate the age. Assuming a daily deposition of increments, our results suggest that M. longimana can live up to 820 days and may hatch throughout the year. Studied individuals presented a consistent growth rate from hatching to death but with, at least, one period of faster growth. A novel pattern of regular cycles, composed of 7–10 lighter increments followed by a darker one, was found in the medium-anterior region of the RSS. Differences were found in the growth rate and size reached at the same age between individuals from the Pacific and Atlantic sectors, which might be related with different environmental conditions between both capture sites. This study shows that lower beaks from predators’ stomachs can be used to study the age of Southern Ocean squids and that M. longimana hatches in all seasons, being available year round to predators that feed of this species.

    Description: Climate change is expected to produce major effects across marine life, and cephalopods seem to benefit from these effects. Of these animals, squids exhibit the greatest levels of biomass and of a substantial importance for human consumption. To test the hypothesis that effects of climate change are beneficial for commercial squid, we used species distribution models on climate scenarios for the period between 2000 and 2014, as well as the years 2050 and 2100 (RCP [representative concentration pathway] 2.6, 4.5, 6.0, and 8.5; CMIP5). Our results suggest that consequences of climate change scenarios are species specific. In the North Pacific and Northwest Atlantic, habitat suitability may increase (from + 0.83% [Doryteuthis pealeii] to + 8.77% increase [Illex illecebrosus]), while the habitat of other species is predicted to decrease (from − 1.03% [Doryteuthis opalescens] to -15.04% decrease [Loligo reynaudii]). Increases in habitat suitability occurred mostly at higher latitudes, while suitable habitat decrease was predicted for the tropical regions. Stronger changes were attained with the harsher emission scenarios. In the future, as a result of warming of the Arctic, squid habitat may increase along both coasts of North America. In the Southern Hemisphere, squids may lose habitat with no poleward habitat alternatives to move into. Contrary to our hypothesis, commercial squid do not stand to benefit from climate change. Since these squid are an important food source for marine megafauna and humans, it is imperative that climate change biogeographic impacts are considered for a sustainable management of this important group of molluscs.

    Description: Climate change could shift the impacts of biological invasions on aquatic ecosystems. Sea freshening is an often-inconspicuous consequence of climatic change that may modify invasive alien species performance in enclosed seas. Several gammarid crustaceans have been particularly successful aliens across fresh, brackish, and marine waters. Here, we use comparative functional responses (feeding rates across resource densities) to examine the ecological impacts of an invasive alien (Gammarus tigrinus) and native (Gammarus locusta) gammarid, present in the Baltic Sea, under three different salinity regimes (14, 10, 6) toward larval chironomid prey. Feeding rates differed between the two species, but these differences depended on salinity, whereby at the lowest salinities, the invasive alien species showed significantly improved performance compared to the native species. Both gammarids exhibited hyperbolic Type II functional responses, with attack rates similar across salinity regimes. Handling times were significantly shortened, and maximum feeding rates heightened, in the alien under sea freshening scenarios compared to the native. These results have implications for enclosed sea systems, where projected freshening could shift the performance advantage toward invasive alien species over natives, thereby exacerbating their ecological impacts.

    Description: The habitat quality of the littoral zone is of key importance for almost all lentic fish species. In anthropogenically created gravel pit lakes, the littoral zone is often structurally homogenized with limited fish habitats. We supplemented deadwood brush piles in the littoral zone of eight gravel pit lakes and investigated the diurnal and seasonal use of this and other typical microhabitats by six dominant fish species. Shoreline habitats were sampled using point abundance electrofishing during day and night in all four seasons, and patterns of fish abundance were compared amongst unstructured littoral habitats, emerged macrophytes and brush piles. We caught a total of 14,458 specimens from 15 species in the gravel pit lakes. Complex shoreline structures were used by all fish species that we examined, especially during daytime, whilst the use of unstructured habitats was highest during night. The newly added brush piles constituted suitable microhabitats for selected fish species, perch (Perca fluviatilis), roach (Rutilus rutilus) and pike (Esox lucius), particularly during winter. Supplemented deadwood provides suitable fish habitat in gravel pit lakes and may to some degree compensate for the loss of submerged macrophytes in winter by offering refuge and foraging habitat for selected fish species.

    Description: We provide a sequence of analysis-ready optical underwater images from the Clarion-Clipperton Zone (CCZ) of the Pacific Ocean. The images were originally recorded using a towed camera sledge that photographed a seabed covered with polymetallic manganese-nodules, at an average water depth of 4,250 meters. The original degradation in visual quality and inconsistent scale among individual raw images due to different altitude implies that they are not scientifically comparable in their original form. Here, we present analysis-ready images that have already been pre-processed to account for this degradation. We also provide accompanying metadata for each image, which includes their geographic coordinates, depth of the seafloor, absolute scale (cm/pixel), and seafloor habitat class obtained from a previous study. The provided images are thus directly usable by the marine scientific community e.g., to train machine learning models for seafloor substrate classification and megafauna detection.

    Description: As alien invasive species are a key driver of biodiversity loss, understanding patterns of rapidly changing global species compositions depends upon knowledge of invasive species population dynamics and trends at large scales. Within this context, the Ponto-Caspian region is among the most notable donor regions for aquatic invasive species in Europe. Using macroinvertebrate time series collected over 52 years (1968–2020) at 265 sites across 11 central and western European countries, we examined the occurrences, invasion rates, and abundances of freshwater Ponto-Caspian fauna. We examined whether: (i) successive Ponto-Caspian invasions follow a consistent pattern of composition pioneered by the same species, and (ii) Ponto-Caspian invasion accelerates subsequent invasion rates. In our dataset, Ponto-Caspian macroinvertebrates increased from two species in 1972 to 29 species in 2012. This trend was parallelled by a non-significant increasing trend in the abundances of Ponto-Caspian taxa. Trends in Ponto-Caspian invader richness increased significantly over time. We found a relatively uniform distribution of Ponto-Caspian macroinvertebrates across Europe without any relation to the distance to their native region. The Ponto-Caspian species that arrived first were often bivalves (46.5% of cases), particularly Dreissena polymorpha, followed secondarily by amphipods (83.8%; primarily Chelicorophium curvispinum and Dikerogammarus villosus). The time between consecutive invasions decreased significantly at our coarse regional scale, suggesting that previous alien establishments may facilitate invasions of subsequent taxa. Should alien species continue to translocate from the Ponto-Caspian region, our results suggest a high potential for their future invasion success highly connected central and western European waters. However, each species’ population may decline after an initial ‘boom’ phase or after the arrival of new invasive species, resulting in different alien species dominating over time.

    Description: Atlantic decadal-to-bidecadal variability (ADV) is described from a multimillennial control integration of a version of the Kiel Climate Model (KCM). The KCM’s ADV is the second most energetic mode of long-term North Atlantic variability in that simulation, whereas the Atlantic multidecadal variability (AMV) is the leading mode that has been described in a previous study. The KCM’s ADV can be regarded as a mixed oceanic gyre-overturning circulation mode that is forced by the North Atlantic Oscillation. The extratropical North Atlantic sea surface temperature (SST) anomalies associated with the model’s ADV initially exhibit a tripolar structure in the meridional direction, which is linked to the gyre circulation. After some years, the SST-anomaly pattern turns into a monopolar pattern located in the subpolar North Atlantic. This transition is related to the overturning circulation. The AMV and the ADV co-exist and share some similarities. Both modes of variability rely on the upper-ocean heat transport into the subpolar North Atlantic. They differ in the importance of the gyre and overturning circulations. In the ADV, gyre and overturning-heat transports into the subpolar North Atlantic are equally important in contrast to the AMV where the overturning contribution dominates.

    Description: The deep-sea mining industry is currently at a point where large-sale, commercial polymetallic nodule exploitation is becoming a more realistic scenario. At the same time, certain aspects such as the spatiotemporal scale of impacts, sediment plume dispersion and the disturbance-related biological responses remain highly uncertain. In this paper, findings from a small-scale seabed disturbance experiment in the German contract area (Clarion-Clipperton Zone, CCZ) are described, with a focus on the soft-sediment ecosystem component. Despite the limited spatial scale of the induced disturbance on the seafloor, this experiment allowed us to evaluate how short-term (〈 1 month) soft-sediment changes can be assessed based on sediment characteristics (grain size, nutrients and pigments) and metazoan meiofaunal communities (morphological and metabarcoding analyses). Furthermore, we show how benthic measurements can be combined with numerical modelling of sediment transport to enhance our understanding of meiofaunal responses to increased sedimentation levels. The lessons learned within this study highlight the major issues of current deep-sea mining-related ecological research such as deficient baseline knowledge, unrepresentative impact intensity of mining simulations and challenges associated with sampling trade-offs (e.g., replication).

    Description: The Clarion Clipperton Fracture Zone (CCZ) in the northeast Pacific is a heterogeneous deep-sea environment, featuring abyssal plains as well as multiple seamounts and abyssal hills (bathymetric elevations) that harbour a highly diverse megabenthic fauna. Based on the analysis of seafloor photographic transects that were taken from elevated areas downslope into the abyssal plains in the eastern CCZ, a similar distribution of habitats was observed on five different bathymetric elevations including abyssal hills as well as the foothills of two seamounts. Rock outcrops occur at the summits, surrounded by an area with varying coverage and size of polymetallic nodules, which were divided into two different habitats characterized by large and small nodules, respectively, and followed by nodule-free sediments. Megafauna composition, density and diversity varies across these habitats. While density is the highest in areas with rock outcrops (1.4 individuals per m 2 ), the biodiversity is the highest when regarding all of the habitats combined. Regarded individually, nodule-covered areas are the most diverse, whereas sediment areas without hard substratum, i.e. nodule free sediments, show the lowest biodiversity and the lowest density (0.2 individuals per m 2 ). The multinomial species classification method (CLAM) shows that most of the observed megafauna morphotypes have to be regarded as rare. The large differences between the megafaunal communities at bathymetric elevations and the abyssal plain reported from previous studies might partly be explained by the multiplicity of habitats. This high heterogeneity can lead to a more diversified community at elevations, although most habitats can also be observed in the abyssal plain.

    Description: The study of marine food web models has increased during the last years, but input data of important groups such as cephalopods are missing sometimes which restricts the quality of the model results. Cephalopods feed on a variety of preys, ranging from small crustaceans to large commercially important fish species. In turn, they are taken by larger invertebrates, fish, cephalopods, marine mammals and seabirds, which emphasizes their important role in various marine food webs. Our study presents stomach content analyses of various cephalopod species from the North Sea and describes their general feeding trends. The results further support the inclusion of cephalopods as predators into food web models to increase our knowledge of the North Sea ecosystem and to improve its management. Our data in combination with observed increasing biomasses of North Sea cephalopods suggest that the impact of cephalopods in the North Sea food web has increased and that large-sized cephalopods have become more important as predators for commercially exploited fish species during recent years.

    Description: Background: Animals are expected to adjust their social behaviour to cope with challenges in their environment. Therefore, for fish populations in temperate regions with seasonal and daily environmental oscillations, characteristic rhythms of social relationships should be pronounced. To date, most research concerning fish social networks and biorhythms has occurred in artificial laboratory environments or over confined temporal scales of days to weeks. Little is known about the social networks of wild, freely roaming fish, including how seasonal and diurnal rhythms modulate social networks over the course of a full year. The advent of high-resolution acoustic telemetry enables us to quantify detailed social interactions in the wild over time-scales sufficient to examine seasonal rhythms at whole-ecosystems scales. Our objective was to explore the rhythms of social interactions in a social fish population at various time-scales over one full year in the wild by examining high-resolution snapshots of a dynamic social network. Methods: To that end, we tracked the behaviour of 36 adult common carp, Cyprinus carpio, in a 25 ha lake and constructed temporal social networks among individuals across various time-scales, where social interactions were defined by proximity. We compared the network structure to a temporally shuffled null model to examine the importance of social attraction, and checked for persistent characteristic groups over time. Results: The clustering within the carp social network tended to be more pronounced during daytime than nighttime throughout the year. Social attraction, particularly during daytime, was a key driver for interactions. Shoaling behavior substantially increased during daytime in the wintertime, whereas in summer carp interacted less frequently, but the interaction duration increased. Therefore, smaller, characteristic groups were more common in the summer months and during nighttime, where the social memory of carp lasted up to two weeks. Conclusions: We conclude that social relationships of carp change diurnally and seasonally. These patterns were likely driven by predator avoidance, seasonal shifts in lake temperature, visibility, forage availability and the presence of anoxic zones. The techniques we employed can be applied generally to high-resolution biotelemetry data to reveal social structures across other fish species at ecologically realistic scales.

    Description: Biological nitrogen fixation is a key process balancing the loss of combined nitrogen in the marine nitrogen cycle. Its relevance in upwelling or high nutrient regions is still unclear, with the few available studies in these regions of the ocean reporting rates that vary widely from below detection limit to 〉 100 nmol N L−1 d−1. In the eastern tropical Atlantic Ocean, two open ocean upwelling systems are active in boreal summer. One is the seasonal equatorial upwelling, where the residual phosphorus associated with aged upwelled waters is suggested to enhance nitrogen fixation in this season. The other is the Guinea Dome, a thermal upwelling dome. We conducted two surveys along 23° W across the Guinea Dome and the Equator from 15° N to 5° S in September 2015 and August–September 2016 with high latitudinal resolution (20–60 nm between stations). The abundance of Trichodesmium colonies was characterized by an Underwater Vision Profiler 5 and the total biological nitrogen fixation in the euphotic layer was measured using the 15N2 technique. The highest abundances of Trichodesmium colonies were found in the area of the Guinea Dome (9°–15° N) with a maximum of 3 colonies L−1 near the surface. By contrast, colonies were almost absent in the Equatorial band between 2° N and 5° S. The highest nitrogen fixation rate was measured at the northern edge of the Guinea Dome in 2016 (ca. 31 nmol N L−1 d−1). In this region, where diazotrophs thrived on a sufficient supply of both phosphorus and iron, a patchy distribution was unveiled by our increased spatial resolution scheme. In the Equatorial band, rates were considerably lower, ranging from below detection limit to ca. 4 nmol N L−1 d−1, with a clear difference in magnitude between 2015 (rates close to zero) and 2016 (average rates around 2 nmol N L−1 d−1). This difference seemed triggered by a contrasting supply of phosphorus between years. Our study stresses the importance of surveys with sampling at fine-scale spatial resolution, and shows unexpected high variability in the rates of nitrogen fixation in the Guinea Dome, a region where diazotrophy is a significant process supplying new nitrogen into the euphotic layer.

    Description: While most coastal communities are expected to, or have been, negatively impacted by climate change, cephalopods have generally thrived with shifting ocean conditions. However, whilst benefitting from the same physiological flexibility that characterizes cephalopods in general, cuttlefish have depth constraints imposed by the presence of a cuttlebone and are limited to specific locations by their particularly low vagility. To evaluate the potential effects of marine climate change on cuttlefish, Species Distribution Models (SDM) were applied to nine species of genus Sepiidae to assess potential changes to their future distribution (2050 and 2100), under four representative concentration pathway (RCP) scenarios (i.e., RCP 2.6, 4.5, 6.0, and 8.5; CMIP5). We show that future cuttlefish habitat suitability and distribution will potentially decrease. The species with the most extreme impacts, Doratosepion braggi (Verco, 1907), was observed to decline as much as 30.77% in average habitat suitability (from present 55.26% to 24.48% at RCP 8.5 in 2100), to Sepia officinalis Linnaeus, 1758 with a low maximum decrease of 1.64% in average habitat suitability (from present 59.62% to 57.98% at RCP 8.5 in 2100). Increases in habitat suitability were projected mostly at higher latitudes, while habitat decrease was predicted for the tropical regions and lower latitudinal limits of species’ distributions. As their habitats decrease in terms of habitat suitability, cuttlefish may not benefit from future changes in climate. Additionally, as potential “sea canaries” for coastal ecosystems, we may see many species and habitats from these systems affected by climate change, particularly in tropical regions.

    Description: The topographic fabric of the rift valley floor has been analyzed using the multibeam echosounder data obtained by the autonomous underwater vehicle (AUV) Abyss at two locations over a short segment of the slow-spreading Central Indian Ridge between 10°18′ and 10°57′S. The region is influenced by hydrothermal venting in the near vicinity. Two AUV dives D51 and D52 were performed over this segment at two locations that are 30 km apart and covered 5 km2 and 8 km2 seafloor area, respectively. The dive D51 covered the off-axis part of the rift valley floor in the middle part of the segment, and the dive D52 is located near to the non-transform discontinuity that covered the terminal part of an oceanic core complex (OCC). High-resolution seafloor topography as revealed by the AUV-mounted multibeam echosounder system brought out several micro-bathymetric fabric features such as a lava lake, a cratered volcano, an OCC, and the foot wall volcanic complex at the distal part of the OCC. The valley floor imaged in the D51 is marked by a lava flow encompassing an area of 1 km2 and a volcano in the NE corner. The volcano has a diameter of about 800 m with an elevation of about 200 m from the adjacent seafloor, and the partially mapped volcano crater has a relief of about 60 m. A prominent linear fissure running parallel to the ridge axis has been identified; this feature joins with the volcano. Analysis of AUV-mounted CTD data indicated three distinct temperature spikes ranging 0.009 to 0.013 °C in the region of dive D51. The observed temperature spikes appear to be related to the linear fissure on the seafloor and probably represent leaky venting of fluids from the fissure. With respect to the dive D52, the foot wall volcanic features associated with the OCC are prominent. The volcanic seafloor feature covered an area of 3.45 km2 and is conspicuous with rugged topographic fabric at the base of the OCC. These inferences and the morphotectonics of the rift valley floor as revealed by the AUV data suggest moderate hydrothermal venting in this segment of the slow-spreading Central Indian Ridge.

    Description: The Campi Flegrei volcanic system is certainly a remarkable case study for what concerns magma chamber dynamics. In fact, its magmatic and volcanic history appears to have been largely driven by chamber processes like fractional crystallization, magma mixing, and volatile degassing. These processes have been intensely investigated with a variety of approache s. Here we employ physico- mathematical modelling and numerical simulations in order to study the dynamics of magma convection and mixing in a vertically extended, geometrically complex, compositionally heterogeneous magmatic system representing a schematic simplification of an overall picture emerging from previous studies at Campi Flegrei . Although clearly a simplification, a number of first order characteristics of possible real magmatic systems at Campi Flegrei are accounted for, including the more chemically evolved, partially degassed nature of magmas emplaced at shallow depths, and the likely occurrence of multiple reservoirs with different depth, size and shape which can be connected at certain stages during system evolution, allowing deeper, CO 2 -rich magmas to rise and rejuvenate the shallow magmas.

    Description: Modern humans are the only fully terrestrial ape. All other apes are \npartially arboreal, particularly as infants and juveniles. Precocial locomotor \ndevelopment, high frequency of arboreal locomotion in early ontogeny, and \nincreased terrestriality throughout development are ubiquitous amongst the \nhominines and likely represent the ancestral state. The role of climbing in \nhominin evolution has been debated for decades, but if hominins climbed \nregularly then subadults likely relied on it most frequently. Investigating the \nrole of climbing throughout hominin evolution requires reliable developmentally \nplastic traits that are responsive to locomotor loading and can be identified in the \nfossil record. Chimpanzees and gorillas provide a natural experiment to examine \nthe relationship between age-related variation locomotor activities and bone \nstructure. Chimpanzees and gorillas are most arboreal during infancy and \nbecome more terrestrial throughout development. Gorillas are comparatively \nmore terrestrial and transition to predominantly terrestrial locomotion at an \nearlier age. This paper has two main objectives. First, to examine if interspecific \ndifferences in the rate of locomotor development is reflected in bone structure. \nSecond, to determine if ontogenetic reductions in the frequency of arboreal \nlocomotion correspond to age-related variation in bone structure.

    Abstract: This book, part of the series Cave and Karst Systems of the World, begins with a review of the interaction between people and caves in Australia (including conservation), followed by descriptions of the spectacular cave diving sites, before comprehensively covering all the major carbonate and noncarbonate karst areas, subdivided by rock type and region, and including the origin of the caves. This is followed by broad overviews of cave minerals and speleothems, cave biology and cave fossils. Each section was written by one or more specialists in the topic and is illustrated by clear diagrams and superb colour photos. The book emphasises the unique aspects of the Australian karst, including the variability in the age of the caves (very old to very young) and the impact of isolation on the stygofauna, as well as the vertebrate fossils preserved in the caves. Written in an easy-to-read style, the book is a primary reference guide to Australian karst and represents a valuable asset for anyone interested in the topic, not only cavers and academics.

    Description: As an expansion of a time-series study on meiobenthos in the Arctic deep sea, the diversity of free-living nematode communities along nine stations along a bathymetric transect was investigated morphologically in taxonomic and functional regards (feeding-type composition, life-history traits, tail-shape composition) and compared with previous studies of the same transect to investigate possible changes in the nematode community composition. Special emphasis was given on the analysis of sedimentary environmental parameters, which are used as proxies for food availability and sediment porosity. Multivariate statistics performed on nematode abundance data revealed a bathymetric zonation into four bathymetric zones: upper bathyal (1300 – 2000 m), lower bathyal (2500 - 3500 m), abyssal (5100 – 5600 m) and an additional ‘outgroup’ consisting of two stations with low nematode densities. Nematode densities generally decreased with increasing depth. Taxonomic diversity (EG〈jats:sub〉(50)〈/jats:sub〉, H’〈jats:sub〉(log2)〈/jats:sub〉, J’) decreased in a unimodal pattern peaking in the lower bathyal zone. A distance-based linear model revealed that 44% of the total variation in nematode abundances could be explained by the measured environmental parameters. Microbial feeders are the dominant feeding type along the transect with increasing dominance in the abyssal zone. The maturity index, a measure of environmental disturbance, decreased with depth, indicating a more colonizer-dominated community in the abyssal zone. Nematodes with long conico-cylindrical tails also become more dominant in the abyssal zone. A previous study of the same transect conducted in 2005 found a similar bathymetric zonation, but with a strikingly different dominant feeding type, i.e. epistrate feeders. Between the 2005 study and the year 2010 we conducted our study, the composition of the plankton community in the Fram Strait changed significantly due to a warm water anomaly in the region. We argue that through bentho-pelagic coupling, effects of this warm water anomaly on plankton communities could be a reason for the drastic change in dominant nematode feeding types.

    Abstract: Chilean Patagonia, located at the southwestern tip of South America, is one of the last regions on earth where highly intact environments predominate. With a coastline that extends along some 100,000 km of fjords, channels, and islands, it has one of the world´s most extensive marine-terrestrial interfaces. Local place-based and Indigenous cultures and management practices are a vital presence across the region, while the long and rich history of conservation efforts have resulted in officially protected areas covering over 50% of the land and 41% of the coastal-marine area. However, Chilean Patagonia is increasingly facing anthropogenic pressures associated with increased infrastructure and access, salmon aquaculture, extractive industries, and the spread of invasive exotic species. Despite widespread recognition that Chilean Patagonia represents a unique global reservoir of socio-natural heritage, to date there has been no region-wide assessment of the scientific evidence of the conservation status of its ecosystems or the priorities for their effective conservation. Conservation in Chilean Patagonia: Assessing the state of knowledge, opportunities, and challenges is the first book to gather and synthesize the available scientific and socio-environmental information related to Patagonian conservation. It presents the collaborative work of 68 researchers and local experts, representing a range of specialties and perspectives, including: biology, ecology, socio-ecology, fisheries, aquaculture, anthropology, economics, geography, tourism, cryosphere, oceanography, climate and global change. The book’s 18 chapters focus on the status of key ecosystems and conservation tools, and provide recommendations toward the construction of a renewed, inclusive, and integrated conservation agenda for the Chilean Patagonian region. It provides an essential primer for anyone interested in the future of this ecologically vital region, as well as lessons on interdisciplinary collaboration and integrated analysis of conservation issues useful for conservation practitioners and scholars. This is an open access book. This book is a translation of an original Spanish edition. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation.

    Abstract: For the past 9,000 years, people lived and flourished along the 1,000-mile Aleutian archipelago reaching from the American continent nearly to Asia. The Aleutian chain and surrounding waters supported 40,000 or more people before the Russians arrived. Despite the antiquity of continuous human occupation, the size of the area, and the fascinating and complex social organization, the region has received scant notice from the public. This volume provides a thorough review describing the varied cultures of the ancestral Unangax̂, using archaeological reports, articles, and unpublished data; documented Unangax̂ oral histories, and ethnohistories from early European and American visitors, assessed through the authors’ multi-decade experience working in the Aleutian Archipelago. Unangam Tanangin ilan Unangax̂/Aliguutax̂ Maqax̂singin ama Kadaangim Tanangin Anaĝix̂taqangis (Culture and Archaeology of the Ancestral Unangax̂/Aleut of the Aleutian Islands, Alaska) begins with a description of the physical and biological world (The Physical Environment and The Living Environment) of which the Unangax̂ are part, followed by a description of the archaeological research in the region (The People). The rest of the book addresses ancestral Unangax̂ life including settlement on the land, and the characteristics of sites based on the activities that took place there (People on the Landscape). From this broad perspective, the view narrows to the people making a living through hunting, fishing, and collecting food along the shore-line, making their intricate tools, storing and cooking food, and sewing and weaving (Making a Living); household life including house construction, households, and the work done within the home (Life at Home); and the personal changes an individual goes through from the time they are born through death, including spiritual transitions and ceremonies (Transitions), and the evidence for these events in the material record. This book is written in gratitude to the Unangax̂ and Aleut people for the opportunity to work in Unangam Tanangin or the Aleutian Islands, and to learn about your culture. We hope you find this book useful. The purpose of this book is to introduce the broader public to the cultures of this North Pacific archipelago in a single source, while simultaneously providing researchers a comprehensive synthesis of archaeology in the region.

    Abstract: This book describes the Central Sahara region, bringing together an unprecedented combination of diverse and often historic research published in different languages in order to describe its varied landscapes and landforms. The Central Sahara region consists of Libya, Algeria, Mali, Niger and Chad, countries that share similar landscape histories and common landscape traits, including massifs, sand seas, paleowater features and large depressions. Furthermore, human settlement of this region goes hand-in-hand with climate and environmental changes and landscape evolution during the Holocene and earlier; hence, Central Saharan landscapes and landforms provide valuable insights into landscape–human relationships over long timescales. The book offers a comprehensive yet accessible reference source, drawing on both past and present interdisciplinary research and gathering the insights of authors from many different countries to explore a region that has largely been overlooked in available literature.

    Abstract: This book provides a detailed evaluation of the hydro-ecological characteristics of the Western Balkans, an area characterized by still preserved inland waters and fish resources important for the European continent, as well as the biodiversity of inland waters important for the planet Earth. Freshwater ecosystems cover only 1% of the Earth's surface; however, they are a habitat for about 40% of fish species. At the same time, inland fisheries make less than 12% of the world's global fish catch, with 43% coming from low-income and food-deficient countries (Africa, South America, Southeast Asia). In Europe, the Western Balkans have significant fishing waters and fish resources, including the Middle Danube drainage (Sava, Drina, Velika Morava river systems), large ancient lakes (Skadar/Shkodra, Ohrid, Prespa, Dojran), and the Adriatic basin characterized by endemic and commercially important species. However, in contrast to the high fishing potential in a significant part of the Western Balkans, diverse and specific political, economic, and social factors largely had a negative impact on the state of fish resources. This volume is multidisciplinary and provides a sound knowledge base for scientific and practical fisheries. In addition, it may be a valuable guide for managers and conservationists worldwide to adapt methods and procedures for the ecological sustainability of fish resources under specific local, natural, and socio-economic conditions. Finally, the content is a good reference for natural sciences and agriculture students studying fish, fish resources, and fisheries sciences. It would improve their knowledge and perspectives on the challenges of sustainable use and conservation of inland water resources.

    Abstract: The global human population will reach nine billion by 2050, and seafood is projected to be the primary food source to sustain such a large population. According to a recent World Bank report, aquaculture will be the prime source of seafood by 2030. Tilapia is one of the promising species for commercial aquaculture and one of the second most farmed fish worldwide. Given the issues raised by Antibiotic misuse in intensive aquaculture, such as the occurrence of resistant bacteria, it is necessary to develop environment-friendly strategies that could be used to improve production in a sustainable manner. Also, there is a need to establish the best aquaculture practice (BAP) approaches to avoid significant disruption to the ecosystem, the loss of biodiversity, and substantial pollution impact on the environment. We believe the current book will be very helpful to academics, researchers, and policy-makers in aquaculture. .

    Abstract: Cold-water corals form reef structures in continental margin and seamount settings world-wide, making them more wide-spread and abundant than shallow-water reefs. Their role in these ecosystems is no less important than the influence that shallow-water coral reefs have on tropical systems. They create habitat structure, host endemic species, enhance elemental cycling, alter current flow, sequester carbon, and provide many other ecosystem services that we are just beginning to understand. The rapidly evolving state of knowledge of cold-water and deep-sea coral reefs has not been compiled in over 10 years. This volume synthesizes recent and historical information, reveals new findings from reefs that have been discovered only recently, and presents key avenues for future research. We are on the cusp of understanding the critical role that cold-water coral reefs play in the world’s oceans, and this book lays the foundation on which this knowledge will be built in the future.

    Abstract: This book offers a comprehensive collection of cutting-edge research on feed additives for a sustainable animal production, including insects and aquaculture. In five clearly structured sections, the sources of feed additives, details on their biochemistry, feed security as well as specific applications for individual farm animal species, livestock health and product characteristics (meat, milk and eggs) find attention. International expert authors provide a full description on the use of aromatic plants, extracts and essential oils as feed additives alone or in combination with functional feeds of different categories. Readers will explore the potential of feed additives to tackle environmental issues. Practical examples include the use of local feedstuffs in combination with herbal additives and enzymes. Emphasis is placed on the consequences of using local feed sources versus imported feedstuffs on global warming potential, primary energy use, nutrient excretion and the feed additive influence on lessening the pollution from animal operations. The results presented will support realization of the Sustainable Development Goals, in particular SDG 12 which stands for Responsible Consumption and Production worldwide. The use of novel and different feed additives can be an important tool to enhance sustainability, support productivity, and match increased food demands around the globe. Animal production depends on feed efficiency to sustain growth and profitability. Along these lines, the present volume is an essential reading for all future-oriented veterinarians, animal nutritionists, agricultural scientists, and moreover the feed, food and plant industry. .

    Abstract: This book focuses on green nanoremediation addressing aspects related to the use of nanomaterials generated through green synthesis protocols to efficiently restore polluted environs. Nanomaterials’ characteristics such as large surface area, capacity to easily reach into contaminated sites, good reactivity, and possibility of being developed to present photocatalytic activity and/or to deal with targeted substances by chemical surface modification are useful specially to perform remediation. As an alternative to conventional physicochemical methods, the green-based synthesis protocols reject the use of harmful reagents, prevent waste production, apply renewable energy source and/or materials, and consider in first place offering the smallest negative impact possible to living beings and to the ecosystem. Green synthesis in nanotechnology field involves the use of seaweeds, bacteria, cyanobacteria, yeasts, fungi, plants (living ones, biomass, extracts) and/or bio-derived products to generate the nanomaterials. The introductory chapter will be dedicated to nanomaterials’ characteristics that enable them to be used in environmental remediation. The first part of the book will be dedicated to organic and inorganic pollution and the threats they pose to living forms; advantages, disadvantages and mechanisms of nanoremediation; comparison between conventional strategies of environmental pollution remediation and the green nanoremediation; carbon-based and non-carbon-based green nanomaterials capable of promoting environs’ remediation; cost/benefits of using nanomaterials and nanoinformatics to a safe nanotechnology. The second part will be dedicated to green nanoremediation of water and soil, microbe-based, algae-based and plant-based synthesis of nanomaterials to nanoremediation. This part will also contain chapters dedicated to relevant nanomaterials for green nanoremediation protocols, nano-phytoremediation strategies, strategies to evaluate the efficiency of protocols related to this kind of remediation, main interactions of green nanomaterials and microbes during nanoremediation and, as a consequence of it, biocompatibility of green nanomaterials. This book’s main purpose is to offer readers extensive knowledge on green nanoremediation as a feasible strategy to fight pollution's harmful consequences and clean environmental pollution, but also present the challenges that should be surpassed.

    Abstract: The health status and future of tropical coral reefs, as tourist destinations, are regularly subjected to media coverage. Many documentaries recognize the natural beauty and biological richness of the Australian Great Barrier Reef and French Polynesian lagoons, but point to the equally significant risk that would result from current global warming and human-made hazards. The future of coral reefs is usually a matter of death foretold, real or purely imaginary. In this context, it has become necessary to differentiate between what is falling within reality of scientific facts or fantasy. To this end, the present general review, in the expert translation of Charlotte Fontan aims at: (1) defining the conditions and life requirements of reefbuilding corals; (2) the history of corals along with that of a number of associated, skeletal organisms involved in reef building since the very beginning, i.e. the last 540 million years, including the ups and downs they have experienced; (3) giving special reference to the development patterns of recent and modern reefs; (4) projecting corals and reefs into a still unknown future. Understanding how corals and reefs have originated, how they have been able to face the major biological crises which have punctuated the Earth’s history, how they have survived is a prerequisite to better gain a significant picture of their future.

    Abstract: As lifespans increase, more people around the world find themselves victims of chronic pain. In spite of this, treatment options continue to be severely limited. Anti-inflammatory drugs can only do so much, while painkillers like opioids have led to crippling addictions and fatal overdoses. The subject of the book is the role of immune cells, including glial cells, and neuroimmune interactions in chronic pain. The book begins by examining the preclinical and clinical evidence supporting the involvement of non-neuronal cells in chronic pain. It discusses the interactions between non-neuronal cells and neurons in the regulation of chronic pain. It then presents the implications of these findings, including promising and emerging treatments such as specialized pro-resolving mediators (SPMs, such as resolvins and protectins), immune cell therapy, and complementary and alternative medicine, as well as neuromodulation and regenerative medicine, which may prove to be the turning point for hundreds of millions of patients world-wide who struggle to escape from the shadow of chronic pain. The book presents ground-breaking research that will alter current perspectives on chronic pain.

    Abstract: This volume presents papers from the biennial International Laser Radar Conference (ILRC), the world’s leading event in the field of atmospheric research using lidar. With growing environmental concerns to address such as air quality deterioration, stratospheric ozone depletion, extreme weather events, and changing climate, the lidar technique has never been as critical as it is today to monitor, alert, and help solve current and emerging problems of this century. The 30th occurrence of the ILRC unveils many of the newest results and discoveries in atmospheric science and laser remote sensing technology. The 30th ILRC conference program included all contemporary ILRC themes, leveraging on both the past events’ legacy and the latest advances in lidar technologies and scientific discoveries, with participation by young scientists particularly encouraged. This proceedings volume includes a compilation of cutting-edge research on the following themes: new lidar techniques and methodologies; measurement of clouds and aerosol properties; atmospheric temperature, wind, turbulence, and waves; atmospheric boundary layer processes and their role in air quality and climate; greenhouse gases, tracers, and transport in the free troposphere and above; the upper mesosphere and lower thermosphere; synergistic use of multiple instruments and techniques, networks and campaigns; model validation and data assimilation using lidar measurements; space-borne lidar missions, instruments and science; ocean lidar instrumentation, techniques, and retrievals; and past, present and future synergy of heterodyne and direct detection lidar applications. In addition, special sessions celebrated 50 years of lidar atmospheric observations since the first ILRC, comprising review talks followed by a plenary discussion on anticipated future directions.

    Abstract: This book presents a cohesive collection of contributions representing an African scholarly voice on some of the most burning and emerging topics and experiences regarding the implementation of REDD+ in Africa from a human rights perspective. It addresses the international human rights obligations of states and non-state actors in the context of REDD+ implementation in Africa; how current practices in various African states reinforce or affect human rights standards; and critical issues concerning the rights of vulnerable groups such as women, Indigenous populations, and forest dwellers in the implementation of REDD+ in Africa. Further, it investigates potential gaps in the existing laws, and how they can be addressed from a comparative point of view. The book also sheds light on the roles that different actors can play in fostering change and identifies best practices in the implementation of REDD+ in Africa. The book offers a rich intellectual resource for various actors in the environmental science, climate and environmental law fields who are often confronted with the challenge of how to manage the delicate balance of forests as a development resource; forests as a climate-change mitigation resource; and forests as a catalyst for the rights of vulnerable populations. The book responds to the imbalance and gaps in REDD+ scholarship. Addressing such lacuna in an edited volume of this nature is essential to the present and future work of practitioners, academics and other actors with a sustained interest in REDD+ in Africa.

    Abstract: Increased environmental and energy concerns have renewed global interest in raw earth as a building material. Low-energy requirements, low-cost, high availability at construction sites, and favorable engineering properties make (EBMs) an attractive alternative to conventional cement-based construction materials. Though the use of native binders to improve soil properties has garnered attention in recent literature, the available knowledge has not been covered in a single document. This book highlights the key soil properties that determine the mechanical performance of earthen building materials, importance of unsaturated soil mechanics in the engineering behavior of earthen building materials, the different types of stabilizers used to improve the engineering performance of earthen building materials including the use of select native binders, the characteristics of compressed earth blocks stabilized with cement and cement + wood ash additives and the improvement in the engineering properties of adobes stabilized with plant fibers and cow dung. .

    Abstract: Integrins are heterodimeric cell surface receptors which anchor cells to different extracellular matrix proteins or act as cell-cell receptors. They play pivotal roles not only across a wide range of physiological processes including tissue morphogenesis, wound healing, and regulation of cell growth, but also in numerous pathological conditions such as autoimmunity, infectious disease, and carcinogenesis. This book aims to provide readers a summary of the most important integrins and their respective biological functions. Readers will learn about knockout- and animal models to study the functionality of key collagen-, laminin-, and nephronectin-binding integrins. Additionally, the role of integrins in pathological tissue remodeling in joints and in developing and diseased cardiac tissue are discussed. Reviews of the current knowledge of the role of integrins in tissue and tumor fibrosis, angiogenesis and tumor progression are an important part of this work. Finally, the book discusses integrins in the context of the immune system, how to target integrin-ligand interactions with antibodies, and the role of integrins as receptors for bacterial and viral cell invasion. Both experienced researchers and clinicians, as well as PhD students who wish to study the extracellular matrix and cell adhesion molecules will find “Integrins in Health and Disease - Key Effectors of Cell-Matrix and Cell-Cell Interactions” authoritative, easily accessible, and vastly informative. The series Biology of Extracellular Matrix is published in collaboration with the American Society for Matrix Biology and the International Society for Matrix Biology.

Climate Model Projections and Potential Action Paths.
    Abstract: This textbook introduces and explains the issues around climate change and its mitigation. It includes topics across disciplines and can be used as a single-volume text by students studying a range of subjects. Among the topics included are: ·How to adopt significant mitigation measures now to avoid the most catastrophic long-term consequences of climate change. ·Reducing the rates of highly potent, short-lived emissions of methane gas and black carbon particulates—reductions that are necessary to meet the temperature targets of the Paris Agreements. ·Implementing wide-ranging adaptation measures to reduce the deaths and economic costs of extreme heat waves, droughts, wildfires, hurricanes, and floods. ·Recognizing the unusually rapid warming in the Arctic, which is disrupting weather patterns in the northern hemisphere and currents in the Atlantic Ocean, causing world-wide sea-level rise, and also causing methane leaks in the Arctic region—leaks that could eventually lead to irreversible global warming consequences. Meeting these challenges effectively requires action by both governments and businesses. The book examines the national and local governmental policies—and business practices—that are needed in sector-specific chapters. An objective of the book is to inform readers about specific problems resulting from climate change—and the wide range of potential government policies and business practices, changes in technologies, and changes in public attitudes and actions that can reduce the emissions and otherwise lessen their impacts. Indeed, a central message is that understanding the issues posed by climate change requires no less than an understanding of climate science, micro- and macro-economics, technologies for mitigation and adaptation measures, as well as politics and law at many governmental levels from local to global. The author has included short case studies that illustrate and integrate multiple analytic perspectives. The book is therefore appropriate for students, professionals, and general audiences with wide-ranging interests and backgrounds.

Mine Water Inrush and Its Prediction -- Chapter 7. Groundwater Contamination and Induced Risk and Hazard in a Karst Aquifer.
    Abstract: This book addresses geohazards by establishing their unique hydrogeological conceptual site models. Geohazards occur in many forms and scales either naturally or induced by human's activities. Many geohazards such as earth fissure, ground collapse and subsidence, mine water inrush, and groundwater contamination are closely related to hydrogeological conditions and their dynamics. Water, either surface water or groundwater, acts as a resource and an enabling agent that elevates geohazard risks in areas that are inherently vulnerable. The book presents case studies to describe identification and investigation methods, monitoring and early-warning techniques, modeling approaches, and engineering measures to prevent, control, and mitigate these geohazards. It targets students, researchers, practitioners, and decision makers who are engaged in water resource management, project planning, and geohazard control and management.

    Abstract: This book, entitled Tracking Environmental Change Using Lake Sediments: Volume 6 – Sedimentary DNA, provides an overview of the applications of sedimentary DNA-based approaches to paleolimnological studies. These approaches have shown considerable potential in providing information about the long-term changes of overall biodiversity in lakes and their watersheds in response to natural and anthropogenic changes, as well as tracking human migrations over the last thousands of years. Although the first studies investigating the preservation of these molecular proxies in sediments originate from the late-1990s, the number of scientific publications on this topic has increased greatly over the last five years. Alongside numerous ecological findings, several sedimentary DNA studies have been dedicated to understanding the reliability of this approach to reconstruct past ecosystem changes. Despite the major surge of interest, a comprehensive compilation of sedimentary DNA approaches and applications has yet to be attempted. The overall aim of this DPER volume is to fill this knowledge gap. .

    Description: At opposite ends of our world lie the poles. In the North, the Arctic, an ocean surrounded by coasts; in the South, the Antarctic continent surrounded by an ocean that separates it from the nearest landmasses. At first glance, the poles could not be more dissimilar owing to their contrasting location, geography, and tectonic and evolutionary history. The amplitude and types of ice cover, though differing between the poles, are influenced by the same climatic, atmospheric, and hydrodynamic processes that affect the entire Earth. Freshwater influx into their coastal areas too—beyond the effects of glaciological changes and dynamics such as glacier melt and increasing meltwater discharges—is different: in contrast to the Arctic, the Antarctic continent and sub-Antarctic islands lack major rivers. However, their latitudinal range and low temperatures, ice shelves, icebergs, sea ice, impacts from tidewater and land-based glaciers, significant seasonal variation in light intensity and, hence, primary productivity, offer parallel environments for organisms that have adapted to such conditions. Although we know much about the similarities and differences from an environmental perspective, there are still many unknowns about how benthic communities, especially the meiobenthos, from both regions compare. In this chapter, we provide an overview of the contrasts and parallels between Arctic and Antarctic meiobenthos and place it into context of their extreme habitats. Following a brief account of Arctic and Antarctic evolution and the historical study of their faunas, we (i) compare how extreme polar conditions affect meiofauna across four main habitats: polar coastal areas and fjords, continental shelves and ice shelves, the deep sea, and sea ice, and we (ii) discuss the implications of climate change on meiofauna in these habitats. Reflecting on (i) and (ii) allowed us to identify frontiers for future research of polar meiofauna, which we put forward in the concluding sections of this chapter.

    Abstract: This volume provides a comprehensive review of programmed cell death pathways and their fundamental role in antiviral host defense. The book deep-dives into the molecular functions and regulation of necroptosis and discusses how viruses induce and manipulate this potent innate cellular sensing system. Initially, understanding of necroptosis emerged from studies on tumor necrosis factor (TNF) signaling that showed the key role of receptor interacting protein kinase 1 (RIPK1) in the activation of receptor interacting protein kinase 3 (RIPK3) which then phosphorylates mixed lineage kinase domain like pseudokinase (MLKL) to execute cells via plasma membrane leakage of cytosolic contents. Since its discovery, multiple facets of the RIPK3-dependent necroptotic machinery have evolved where the requirements for execution of death varies depending on the stimulus. Virus-induced necroptosis was discovered over 10 years ago in studies on murine cytomegalovirus (MCMV) where a virus-encoded inhibitor was shown to prevent the recruitment of RIPK3 (RIP3). This transformative evidence identified a novel pathway acting independent of TNF, interferon or RIPK1 that can stop virus from infecting its natural mouse host by killing off infected cells to halt replication. Over the past decade influenza A virus (IAV), herpes simplex virus (HSV) and poxvirus vaccinia (VACV) have all been shown to trigger the pathway. Herpesviruses and poxviruses also encode inhibitors of caspase-8 whose elaboration unleashes the necroptosis pathway. IAV and other RNA viruses do not encode programmed cell death inhibitors. RIPK3 is also known to induce apoptosis by recruiting RIPK1 as shown nearly a decade ago and this dual apoptosis/necroptosis induction occurs naturally during influenza A virus infection. RIPK3 is also able to induce an inflammatory response independently of programmed cell death that can predominate to drive inflammatory disease outcomes. This volume is a must-read for researchers and advanced students in immunology and virology.

    Abstract: This book addresses the phenomenon of biological autoluminescence (also known as ultraweak photon emission, UPE, biochemiluminescence, or biophotons) and deals with a very broad spectrum of subjects, ranging from basic observational studies to molecular mechanisms, free-radical processes, physics of electron excitation and photon emission, as well as detection techniques. The chapter topics include UPE in plants, animals, and the human body; microorganisms and subcellular structures; and model systems, illustrating its high prevalence. Several sections of the book provide some backstory, with emphasis on methodology, unresolved questions, and existing controversies. The authors raise and discuss complex, potentially divisive aspects: Are there any reasons to assume the existence of non-chemical interaction in biological systems? Can research results in the field of mitogenetic radiation, delayed luminescence, and oxychemiluminescence of model systems, be correctly interpreted? What does the future hold for this area of research? Altogether, this publication gives the reader a thorough overview of biological autoluminescence (UPE, biophotonics) research, making it ideal for students and researchers who are new to the area as well as those who are specializing in it.

    Abstract: This book is the first collection of state-of-the-art research projects analyzing water conflict and cooperation with an explicitly theoretical point of view. Its fourteen chapters offer a comprehensive and up-to-date overview on how the application of various theoretical perspectives can support the work of scholars and practitioners in mitigating water conflict and developing cooperation. The volume starts out from a literature review on the theorization of transboundary waters in International Relations, which prepares the ground for the demonstration of the latest approaches of scholars currently working on this field. The discussion of their findings is divided into four main sections. The first section deals with reflections and critiques on the grand theories of International Relations, proposing new and more nuanced frameworks for understanding and managing transboundary water relations by going beyond the traditional assumptions. The second section focuses on the catalysts and barriers of cooperation, applying theoretical frameworks which reveal the consequences of the dynamics in power relations and institutional frameworks. The third section investigates into the perspectives at the intersections of theory and practice related to the most practical field within the scope of the volume: water diplomacy. The fourth section introduces new perspectives to provide specific entry points for understanding and managing water conflict and cooperation. Overall, the work intends to demonstrate that the theorization of transboundary waters can significantly contribute to the deeper understanding and the more efficient management of water conflicts and cooperation from several aspects. The authors come from diverse backgrounds, and their individual careers are often related to the intersections of theory and practice in the field of transboundary water management. Their expertise covers water issues from all around the globe, which is reflected in the range of the analyzed case studies. The diversity of the experts involved, their backgrounds, their perspectives, the applied theories, and the analyzed cases was an important priority for the editors. .

    Abstract: Many wild animals in human care live longer than their wild counterparts because of modern care and wellbeing programmes, leading to a growing demographic of ageing animals. This handbook is dedicated to their care. As an innovative expert publication, it integrates all aspects of professional care, including topics such as behaviour, ethics, environmental enrichment, training, veterinary care, nutrition and habitat design. Each animal is unique in their preferences, physical and emotional needs. Ageing animals may change their behaviour, alter the use space, and may also experience events and their relationships with their carers differently than they used to. The ageing process and death of an individual can be a significant event for others in their group, as well as the human carers. This book consolidates best practices for supporting and assessing optimal ageing animal wellbeing. It describes practical and science-informed approaches and philosophies regarding the care of ageing wild animals in zoos, aquariums, sanctuaries, universities and laboratories in a single source. This is an invaluable reference for veterinarians, animal care professionals, animal welfare researchers and students, and anyone with an interest in caring for animals. Personal stories and beautiful images of ageing individuals brightening the start of each chapter and remind us that what we do must be in the best interest of the animal and be at the heart of their care.

    Description: Dieses Kapitel behandelt die visuelle Navigation von autonomen Unterwasserfahrzeugen (AUVs) mit und ohne gegebene Karte, wobei Letzteres als Simultane Lokalisierung und Kartierung (SLAM) bezeichnet wird. Wir fassen die Herausforderungen und Möglichkeiten in Unterwasserumgebungen zusammen, die die visuelle Navigation von der Landnavigation unterscheiden, und geben auch einen kurzen Überblick über den aktuellen Stand der Technik in diesem Bereich. Dann argumentieren wir als Positionspapier, warum viele dieser Herausforderungen durch eine angemessene Modellierung von Unsicherheiten in der SLAM-Darstellung bewältigt werden könnten. Dies würde insbesondere dem SLAM-Algorithmus ermöglichen, die Mehrdeutigkeit zwischen „Ich sehe das gleiche Merkmal wieder“, „Ich sehe ein anderes, aber ähnlich aussehendes Merkmal“ und „Die Umgebung hat sich verändert und das Merkmal hat sich bewegt“ gründlich zu behandeln.

    Abstract: Epigenetic alterations are heritable changes that play a key role in human development and tissue-specific gene expression patterns. These changes can lead to alterations involved in tumor formation, imprinting, and metabolic disorders. Recent advances can help us understand the importance of epigenetic changes in both cancer development and tumor progression. In addition, epigenetic alterations may also be useful diagnostic and prognostic markers for the analysis of tumor progression. Split into two parts, the book opens with a comprehensive overview of the identification and analysis of epigenetic changes in cancer and the consequences of such changes during tumor development. The second part focusses on cancer specific epigenetic alterations and discusses the potential use of epigenetic markers as biomarkers in diagnosis, early cancer progression, and prognosis. Moreover, it reviews the therapeutic potential of epigenetic drugs. Given its scope, Cancer Epigenetics is an indispensable resource not only for researchers working in the field of human epigenetics and cancer research but also for advanced students seeking for an introduction into epigenetic mechanisms. .
