Description: Geoengineering is regarded by advocates as a creative and responsible technological option in the face of a climate emergency. Critics often see it as a hubristic attempt to play God, with disastrous consequences for the planet and humanity. These antipodal perspectives are represented by the ideal types of Prometheans and Gaians. Prometheans and Gaians typically talk past each other. The geoengineering debate can be made more fruitful by well articulating their respective positions and subsequently situating them in the discourse of sustainability. A sustainability orientation does not answer the troubling question whether geoengineering should be developed and deployed. But it can foster a ‘fusion of horizons’ between Prometheans and Gaians, providing common ground in an otherwise polarized debate and making a more productive dialogue possible.

Description: Hydroacoustic and optical remote sensing have been commonly used to map shallow nearshore benthic features. However, the number, type, scale, and accuracy of the mapping products that can be obtained from the two sensors differ; as such, there can be limited agreement between their mapping products. These differences can be further accentuated if the hydroacoustic data are interpolated to produce a map. Interpolation introduces spatial uncertainty and reduces map accuracy. Consequently, maps generated from the two sensors may provide dissimilar spatial and temporal representations of the same benthic features. We therefore compared the performance of a random forest regression (RFr) and a universal kriging (UK) interpolation method and a post-classification enhancement that can be used to increase the accuracy and complementarity of benthic habitat maps derived from hydroacoustic data. First, we used single beam echosounder (SBES) survey bathymetry data from the Bluefields Bay marine protected area (MPA) in western Jamaica (13.82 km2 in size), to create a bathymetric surface model (BSM), from which rugosity and bathymetric position index (BPI) maps were generated. Next, the RFr was used to create submerged aquatic vegetation (SAV) percentage cover maps from the SBES SAV cover data by predicting cover at un-sampled locations. Predictors included auxiliary data such as depth, BPI, survey points coordinates and radiometrically corrected, deglinted and water column corrected image reflectance index values from each of the following: WorldView-2, Geoeye-1 and Landsat 8. Additionally, a SAV map was created using the UK. The most accurate SAV cover thresholds were identified and were used to create binary maps from the RFr and UK maps. A rugosity derived coral reef map was then added to the binary maps. The resulting benthic habitat maps had comparable accuracies and class coverage to benthic maps classified from GeoEye-1 and WorldView-2 images using pixel and object-based classifiers. However, map accuracies were calculated using a suboptimal number of reference points (〈50) for two of the benthic map classes (SAV absent and coral reef). This was not considered to be problematic as the addition of the coral reef class to the binary maps resulted in a significant decrease in uncertainty (standard error and confidence interval width of the overall accuracy) and a significant increase in the user’s accuracy of the SAV absent map class. Also, the difference in uncertainty and accuracy between the map classes did not change. The methods used in this study can therefore be used to increase the accuracy (and to decrease the uncertainty) and the complementarity of maps derived from hydroacoustic data.

Description: A series of triaxial compression tests of frozen sandy soil are carried out under five confining pressures (1 MPa, 4 MPa, 6 MPa, 8 MPa and 10 MPa) at –6 °C. By comparing the grain size distribution curves of frozen sandy soil before and after shearing, it is found that significant particle breakage can occur during triaxial shearing. Particle breakage changes internal structure of geomaterials and has a significant effect on their stress–strain relationships. In order to accurately describe the effect of particle breakage of frozen sandy soil on the stress–strain relationships, an elastoplastic constitutive model for frozen sandy soil considering particle breakage is proposed. Based on the energy balance equation established by Indraratna and Salim, the constant critical state stress ratio (Mcr) in the energy balance equation is modified to the stress ratio (M) which changed with shear strain during the shearing process. A yield function, considering particle breakage, is proposed using the modified energy balance equation. The hardening law is determined based on the rebound test results of frozen sandy soil, and the associated flow rule is adopted in the model. Compared with experimental data, the model can well simulate the stress–strain relationships under different confining pressures for frozen sandy soil. • Highlights • The particle breakage characteristics of frozen sandy soil are studied. • The energy balance equation considering particle breakage is modified to calculate the energy dissipation of frozen sandy soil. • An elastoplastic constitutive model for frozen sandy soil considering particle breakage is proposed.

Description: Surfactant-mediated extraction (SME), pressurized liquid extraction (PLE), and enzyme-assisted extraction (EAE) have been compared to improve the isolation of phlorotannins from the brown algae Lobophora variegata. Enzymatic treatment with Alcalase 2.4 L FG, Carezyme 4500 L, protease from Streptomyces griseus, pectinase from Aspergillus niger, Celluclast 1.5 L, protease from Bacillus licheniformis; surfactant extraction with triacetin and guaiacol and PLE with ethanol:water as extracting solvent, have been studied in terms of total phenolic content by the Folin–Ciocalteu method and total phlorotannin content using the DMBA assay. The results showed that SME yields the highest amount of phenols and phlorotannins by using food grade guaiacol as the surfactant. An extraction protocol was developed to maximize the amount of extract obtained from L. variegata. The effects of various parameters such as the type of surfactant, efficacy of surfactant, and optimum pH, on the extraction efficiency of polyphenols were examined. The simultaneous use of the enzyme and surfactant was also investigated. However, a synergistic effect between the enzymes and the surfactant for the extraction of polyphenols has not been observed. Considering total phenols and total phlorotannins in the extract, the extraction yield were obtained for total phenols as SME 〉 EAE 〉 PLE and for total phlorotannins as SME 〉 PLE 〉 EAE.

Description: The Ponto-Caspian round goby (Neogobius melanostomus Pallas, 1814) is a prominent invasive species in many European waters. Eggs of the Western Baltic Spring Spawning Atlantic herring might be attractive prey for the invasive round goby during the spawning season. However, investigations of the small fish fauna in an important spawning area of herring, which was characterized by high densities of macrophytes, indicated a spatio-temporal mismatch of round goby and herring spawn in spring, at least on some of the known important spawning beds situated on vegetated sandy bottoms. In contrast, a spatio-temporal overlap between round gobies and herring spawn was observed in a more structured area, characterized with stones, where round gobies’ stomachs were sampled. Further field study results suggest that large round gobies (〉 10 cm) do not feed on herring eggs, while smaller round gobies (〈 10 cm) do so. To support these results, we conducted laboratory feeding experiments with round gobies. When C. crangon, M. edulis and herring eggs were offered simultaneously, round gobies preferred C. crangon. M. edulis was preferred over herring eggs when C. crangon was absent. The predatory impact of the round goby on herring eggs seems to be of minor importance compared to other species, such as three-spined stickleback or perch. Applying the same data, different food ‘preference indices’ revealed a discrepancy in preference between indices. Therefore, we propose a modified food preference index (mE), taking into account four important parameters and combining benefits of two commonly applied indices.

Description: Gas hydrates continue to attract enormous attention throughout the energy industry, as both a hindrance in conventional production and a substantial unconventional resource. Scientists continue to be fascinated by the hydrates’ ability of sequestering large amounts of hydrophobic gases, unusual thermal transport properties and unique molecular structures. Technologically, clathrate hydrates promise advantages in applications as diverse as carbon sequestration and water desalination. The communities interested in hydrates span traditional academic disciplines, including earth science, physical chemistry and petroleum engineering. The studies on this field are equally diverse, including field expeditions to attempt the production of natural gas from hydrate deposits accumulated naturally on the seafloor, to lab-scale studies to exchange CO2 for CH4 in hydrates; from theoretical studies to understand the stability of hydrates depending on the guest molecules, to molecular simulations probing nucleation mechanisms. This review highlights a few fundamental questions, with focus on knowledge gaps representing some of the barriers that must be addressed to enable growth in the practical applications of hydrate technology, including natural gas storage, water desalination, CO2 – CH4 exchange in hydrate deposits and prevention of hydrate plugs in conventional energy transportation.

Description: Fermentation plays a fundamental role in organic carbon degradation on a global scale. However, little is known about how environmental variables influence this process. In a step towards quantifying how temperature and composition influence fermentation, we have calculated the Gibbs energies of 47 fermentation reaction, ΔGr, from 0–150 °C for a broad range of compositions representing microbial habitats as variable as sediments, estuaries, soils, and crustal rocks. The organic compounds in these reactions include amino acids, nucleic acid bases, monosaccharides, carboxylates, methanogenic compounds and more. The amount of energy available varies considerably, from +54 kJ (mol C)−1 for palmitate fermentation, to −184 kJ (mol C)−1 for methylamine disproportionation. For some reactions, there is little difference in ΔGr between low and high energy systems (e.g., the monosaccharide reactions) while others span a much broader range (e.g., the nucleic acid bases). There is no clear-cut trend between exergonicity and temperature, and the values of standard state Gibbs energies of reactions, ΔG0r, for nearly half of the reactions lie outside the range of ΔGr values. To carry out some of these calculations, the thermodynamic properties for six organic compounds were estimated: dimethylamine, trimethylamine, resorcinol, phloroglucinol and cyclohexane carboxylate and its conjugate acid.

Description: As an emerging technology, hyperspectral imaging (HSI), which combines both advanced spectroscopy and imaging techniques, provides sufficient information for spectral and spatial analysis and is thus suitable for distribution and property investigation of nanoscale materials. Considering the applications of HSI have spread from remote sensing to quality control of macro products such as food and milk, this article reviews recent research of HSI in a new field of nanoscale materials. On the basis of fundamental parts of a HSI system, new techniques fitting specifically for nanoscale materials imaging such as dark field and Raman spectroscopy are introduced. Nanoscale materials, including metal nanoparticles, carbon nanotubes and graphene, biological components in cells and tissues, as well as multi-layer nanoscale materials, are the research hotspots utilizing HSI technology. Related research reports of the above materials are reviewed based on the physical distinction of these nanoscale materials. It is believed that HSI technology is a strongly potential technique for property investigation and manipulation of nanomaterial for various applications.

Description: DNA barcoding analysis, using tufA, revealed considerable differences between the expected and observed species inventory of Ulva sensu lato in the Baltic and North Sea areas of the German state of Schleswig-Holstein. Of 20 observed genetic entities, at least four (U. australis, U. californica, U. gigantea and Umbraulva dangeardii) had been introduced recently, whereas three others (one Ulva sp. and two Blidingia spp.) could not be identified at the species level and could also represent recently introduced species. In addition, the observed distributions of Kornmannia leptoderma and U. rigida were much more extensive than indicated by historical records, whereas Blidingia minima and Gayralia oxysperma were absent or much less common than expected. Barcoding analysis also revealed that both U. tenera (type material) and U. pseudocurvata (historical vouchers) from Helgoland, an off-shore island in the North Sea, actually belong to U. lactuca, a species that appears to be restricted to this island. Furthermore, past morphological descriptions of U. intestinalis and U. compressa have apparently been too restrictive and have been responsible for numerous misidentifications. The same is true for U. linza, which, in northern Germany, clusters into two genetically closely related but morphologically indistinguishable entities. One of these entities is present on Helgoland, while the second is present on North Sea and Baltic Sea mainland coasts.

Description: To resolve historical misinterpretations of species descriptions and to comprehend the morphological diversity together with the distribution of Ulva compressa Linnaeus in northern Germany, a morphological and molecular study was undertaken of recently collected specimens and herbarium vouchers. Phylogenetic analyses from sequences of the plastid encoded tufA gene confirmed that U. compressa is abundant along the German Baltic Sea and North Sea coasts. We were able to genetically confirm the presence of U. compressa in the Baltic Sea below salinities of 15 PSU. However, we detected morphologies agreeing with the attached and branched tubular type material only in the North Sea, while U. compressa on Baltic Sea coasts indiscriminately exhibited a very distinct morphology of sheet-like thalli that were always unattached, with the exception of one collection site. Drifting forms were also frequently detected in the Wadden Sea, but not on the island of Helgoland. The tufA sequences of attached and tubular forms of U. compressa from the German Wadden Sea were identical to the drifting sheets found in the Wadden and Baltic Seas and the sequence divergence was extremely small at ≤0.9%. The proliferating, blade-like thalli of U. compressa appear as a nuisance ecotype that is able to form massive accumulations associated with oxygen depletion. Mass accumulations were observed to cause severe damage and increased mortality of habitat forming Zostera and Ruppia populations.

Description: Cytospora is a genus including important phytopathogens causing severe dieback and canker diseases distributed worldwide with a wide host range. However, identification of Cytospora species is difficult since the currently available DNA sequence data are insufficient. Aside the limited availability of ex-type sequence data, most of the genetic work is only based on the ITS region DNA marker which lacks the resolution to delineate to the species level in Cytospora. In this study, three fresh strains were isolated from the symptomatic branches of Elaeagnus angustifolia in Xinjiang Uygur Autonomous Region, China. Morphological observation and multi-locus phylogenetic analyses (ITS, LSU, ACT and RPB2) support these specimens are best accommodated as a distinct novel species of Cytospora. Cytospora elaeagnicola sp. nov. is introduced, having discoid, nearly flat, pycnidial conidiomata with hyaline, allantoid conidia, and differs from its relatives genetically and by host association.

Description: The long-term trend of diurnal temperature range (DTR) over Nigeria was examined using daily station-based datasets for the period 1971–2013. The results show that the regionally averaged DTR has decreased significantly (−0.34°C per decade) over the Nigerian Sahel (north of 10°N), but there has been a slight increasing trend (0.01°C per decade) over the Nigerian Guinea Coast. The annual decreasing trend of DTR in the Nigerian Sahel is mainly attributable to the significant increasing trend in daily minimum temperature (Tmin, 0.51°C per decade), which far outstrips the rate of increase in the daily maximum (Tmax, 0.17°C per decade). In contrast, the comparable trends in Tmin (0.19°C per decade) and Tmax (0.20°C per decade) may explain the non-significant trend of the DTR averaged over the Guinea Coast region. It is observed that the DTR has decreased more in boreal summer (June–July–August) than in boreal winter (December–January–February) for the regions. Furthermore, it is found that the significant DTR declining trend over the Nigerian Sahel is closely associated with an increasing trend of annual and summer precipitation in the region, but the increasing DTR trend in the Nigerian Guinea Coast region can be attributed to the decreasing trend of cloud cover over the region.

Description: This report presents the results of the third and the last workshop in the series “Yamal 2040” organised within Blue-Action work package WP5 “Delivering and valuing climate and information services”. The Blue-Action team at the Institute for Advanced Sustainability Studies (IASS) in cooperation with the Primakov National Institute of World Economy and International Relations of the Russian Academy of Science (IMEMO) and Foresight Intelligence, and with inputs provided by the National Oceanographic Center (UKRI-NOC) and the M. Obukhov Institute of Atmospheric Physics Russian Academy of Sciences (IAP-RAS) in the Blue-Action work package WP2 “Lower latitude drivers of Arctic changes” developed forward-looking scenarios to better understand the risks and opportunities associated with multiple developments in the Arctic and help stakeholders to adapt to them. This case study looks at a specific region, the Yamal-Nenets Autonomous Okrug in Arctic Russia (YNAO or Yamal region), a region with substantial ongoing and planned petroleum and shipping activities. Together with stakeholder groups, the team has co-developed a suite of scenarios to describe possible futures for this region in 2040 by incorporating cutting edge climate predictions with environmental, social and cultural concerns, economic opportunities, and political and legal developments. The scenarios are the outcome of a truly co-design and co-development process involving partners, stakeholders and using various foresight methods tailored to the project’s needs. These methods allow to constructively deal with cognitive biases, thus enabling participants to think out of the box when planning the future. This approach is very helpful in tackling complex issues linked to numerous interacting uncertainties.

Description: Wir zeigen, wie die vorgeschlagene 1000 m-Abstandsregelung zwischen Windkraftanlagen und Wohngebäude den Ausbau der Windkraft an Land in Deutschland praktisch stoppen würde. Wir zeigen auch, dass ein Abstand von 600 m gleichzeitig den Schutz der Anwohner und der Ausbau der Windkraft möglich machen kann.

Description: Following more than a decade of informal deliberations, States at the United Nations (UN)are currently negotiating an “international legally binding instrument for the conservation and sustainable use of marine biodiversity in areas beyond national jurisdiction” (“BBNJ Agreement”). The negotiations aim to strengthen the international legal framework for the protection and management of the global ocean by addressing gaps in the current framework and building on existing obligations under the UN Convention on the Law of the Sea (UNCLOS) to cooperate to protect and preserve the marine environment and conserve marine living resources. This policy brief explores how integrated ecosystem-based management (EBM) in marine areas beyond national jurisdiction (ABNJ) can be advanced at the regional level and how the BBNJ Agreement can build on experiences in other legally binding agreements to strengthen regional cooperation, coordination and coherence. To this end, five building blocks are identified: 1. A robust global body such as a Conference of Parties capable of taking decisions and adopting recommendations; 2. A suite of regional mechanisms for integrated policy development and coordination; 3. Effective science-policy advisory mechanisms; 4. Overarching environmental obligations and principles; and 5. Operational principles to ensure good governance. A review of the current President’s draft text of the BBNJ Agreement highlights where the text could be strengthened to advance EBM. In particular, the BBNJ Agreement could draw inspiration from a range of existing instruments and craft specific obligations to: cooperate to promote in-situ conservation of ecosystems and natural habitats; mainstream biodiversity into all decision-making bodies and processes; and strengthen regional cooperation by supporting existing institutions and by building cross-sectoral platforms for cooperation.

Description: The overall aim of WP2 is to understand both the actual and possible application of the precautionary principle in eight different cases, and explain potential commonalities and differences in the application of the precautionary principle in the cases. This analysis should reflect the particular context of the case and reveal the arguments that have been used for invoking the precautionary principle and/or adopting precautionary measures (even without mentioning the precautionary principle). The multiple case study component of the RECIPES project is one of the key analytical phases of the project. Within the scope of the entire RECIPES project, WP2 builds on aspects of WP1, in particular the final WP1 report taking stock of the precautionary principle since 2000. The outputs of WP2 will feed directly into WP3, with the aim of the development of new tools and approaches to the PP in a co-creation approach. This document is intended for the individual case study analysis, and does not directly inform the cross-case comparison analysis which will take place in task 2.4.

Description: The IASS – and the research project Co-creation and Contemporary Policy Advice, in particular – aim to support policymakers in their efforts to address complex societal challenges within the context of a broad transformation towards sustainability. These challenges are interwoven with other issues and embedded within dynamic contexts that are characterized by a high degree of uncertainty, making it difficult to develop a unified approach to their resolution. In response to this, this IASS Discussion Paper presents a model for the development of co-creative policy advice that is intended to support actors from policymaking and public administration in addressing such complex challenges. The primary goal of the process outlined here is the development, in cooperation with relevant stakeholders, of an in-depth understanding of a specific challenge – before appropriate strategies and measures for its resolution are put in place. The insights gained in this scoping process shape the development of tailored solution generation processes and the allocation of public procurement contracts for the implementation of societal transformation processes. In this approach, the policy advice process begins well before potential solutions are developed and presented to policymakers and administrative bodies. Rather, this model responds to the need to develop an integrated understanding of societal challenges in close cooperation with the people and institutions affected on the ground before public procurement processes for their resolution are launched.

Description: Tras más de una década de deliberaciones informales, los Estados de las Naciones Unidas (ONU) están negociando actualmente un „instrumento internacional jurídicamente vinculante para la conservación y el uso sostenible de la biodiversidad marina en las áreas situadas fuera de la jurisdicción nacional“ („Acuerdo BBNJ“). El objetivo de las negociaciones es reforzar el marco jurídico internacional para la protección y la gestión de los océanos globales, colmando las lagunas del marco actual y aprovechando las obligaciones existentes en virtud de la Convención de las Naciones Unidas sobre el Derecho del Mar (CONVEMAR) para cooperar en la protección y la preservación del medio ambiente marino y la conservación de los recursos marinos vivos. Este informe explora cómo la gestión ecosistémica (EBM, por sus siglas en inglés) en las áreas marinas fuera de la jurisdicción nacional (ABNJ, por sus siglas en inglés) puede ser promovida a nivel regional y cómo el acuerdo BBNJ puede aprovechar las experiencias de otros acuerdos legalmente vinculantes para fortalecer la cooperación, la coordinación y la coherencia regional. Para ello, se han identificado cinco bloques de construcción: 1. Un órgano global sólido, como una Conferencia de las Partes, capaz de tomar decisiones y adoptar recomendaciones; 2. Un conjunto de mecanismos regionales para el desarrollo y la coordinación de políticas integradas; 3. Mecanismos eficaces de asesoramiento científico-político; 4. Obligaciones y principios medioambientales generales; y 5. Principios operativos para garantizar una buena gobernanza. Un examen del actual proyecto de texto del Presidente del acuerdo BBNJ pone de relieve los aspectos en los que el texto podría reforzarse para hacer avanzar la EBM. En particular, el acuerdo BBNJ podría inspirarse en una serie de instrumentos existentes y establecer obligaciones específicas para: cooperar en la promoción de la conservación in situ de los ecosistemas y los hábitats naturales; integrar la biodiversidad en todos los órganos y procesos de toma de decisiones; y reforzar la cooperación regional apoyando a las instituciones existentes y creando plataformas de cooperación transectoriales.

Description: Das vorliegende Papier ist eine Zusammenfassung der Ergebnisse der Arbeitsgruppe Global Commons der Wissenschaftsplattform Nachhaltigkeit 2030 (WPN 2030) (Laufzeit Januar 2018 – Dezember 2019). Die Plattform wurde 2017 gegründet, um die Umsetzung der Agenda 2030 und ihrer Sustainable Development Goals (SDGs) sowie der Deutschen Nachhaltigkeitsstrategie (DNS) wissenschaftlich zu begleiten. Im Rahmen der Arbeitsprozesse wurde die Nutzung und Governance sogenannter Global Commons als ein zentrales Thema von Nachhaltigkeitspolitik in, mit und durch Deutschland identifiziert. Kernziel der eingesetzten Arbeitsgruppe war es, aus einer sektorenübergreifenden Bestandsaufnahme der Governance zentraler Commons Handlungsempfehlungen abzuleiten, wie Deutschland zur Stärkung der globalen Nachhaltigkeitsarchitektur in diesem Bereich beitragen kann. Zu diesem Zweck fokussierte sich die Arbeitsgruppe auf die folgenden zentralen Umweltressourcen mit Bezug zur Agenda 2030: (i) Wälder, (ii) Böden/Biodiversität, (iii) Ozeane und (iv) Süßwasser. Zur Vertiefung dieser Bereiche wurden vier Hintergrundstudien in Auftrag gegeben, welche die globale Governance der jeweiligen Ressourcen und die Rolle Deutschlands analysieren.

Description: In a decarbonised future electricity system, Europe will rely on fluctuating renewable sources, such as solar PV and wind power, to a much larger extent than today. This means that Europe as a whole and each individual country on the continent must increase the availability of flexibilityoptionsin order to balance the grid. Such flexibility options include dispatchable renewable sources (e.g. concentrating solar power (CSP)with thermal storage), electricity storage, anddemand-response. We start from the notion that the future does not happen, but it is madeby a series of policy decisions between now and then. If this is true, then the electricity system of 2050 is determined by the sum of all policy decisions affecting the power system – the policy pathway – in all legislations in Europeuntil 2050. In this report, we take the first steps towards identifying the potential future role for dispatchable renewables – specifically CSP with thermal storage – as a function of policy decisions that either increase the need for power system flexibility (e.g. fluctuating renewables) or provide flexibility (e.g. storage, dispatchable renewables, flexible demand). We draw on the energy transition logics framework developed by Foxon and colleagues. This framework poses that the space of possible energy transition pathways is a triangle with three distinct policy logicsin its corners: a state-centred logic, in which the central government leads or carries out the transition; a market-centred logic, in which the government sets the framework but leaves all other decisions to market actors; and a grassroots-centred logic, in which the transition is carried out locally with the resources available to each community. Any transition strategy will consist, in some constellation, of policies from these corner. We investigate policy strategies in France, Germany, Spain, Italy, Switzerland and of the European Union as a whole. For each case, we define one dominant pathway, consisting of currently valid, implemented policies of the current (or newly resigned) government. In addition, we identify up to three minority pathwaysfor each case, describing the energy policy visions and strategies of parties that are currently in opposition but could form a government in the future. For each case, we identify pathways representing each of the three logics, bothin narrative formand as a set of 41 quantitative variables affecting the need for and provision of power system flexibility. This report is a primary data source for the power system modelling in the MUSTEC project. This modelling will happen in 2019 and 2020, and will bring detailed, quantitiave insights of how the potential role for dispatchable renewables is affected by energy policy decisions. However,from the data we have derivedhere, we can draw a number of conclusions. We show that all countries and the EU as a whole seek to strongly decarbonise their power systems, as a key part of economy-wide decarbonisation efforts. Some countries have plans that would suffice to fulfil the European (Union and national) commitments under the Paris Agreement: net-zero emissions, mainly or exclusively based on renewables. We also show that all countries seek to vastly expand intermittent renewables, which will trigger a greatly increased need for flexibility. However, this is not reflected in the policies we analysed: no pathway, dominant or minority, is specific on how they want to provide flexibility, especially not at the scale and pace needed. This problem will be exacerbated as the climate targets are tightened and fossil fuels – first coal and lignite (mainly in the 2020s) and later gas power (especially in the 2040s) – are phased out: once this happens, the European power system(s) will lose much of its current flexibility, and unlessother, carbon-free flexibility options are expanded, it will be increasingly difficult to maintain power system stability.

Description: Das Diskussionspapier untersucht die bilateralen Energiepartnerschaften der Bundesregierung - eines der zentralen Elemente der deutschen internationalen Energiewendepolitik. Gestützt auf eine umfassende Datenanalyse liefert es eine Bestandsaufnahme der Ziele, Umsetzung und inhaltlichen Schwerpunkte der Partnerschaften. Zudem arbeitet es deren Rolle in der bilateralen Energiezusammenarbeit heraus. Das Diskussionspapier liefert damit erstmals eine umfassende wissenschaftlich fundierte Analyse zur Gestaltung dieses wichtigen Politikinstruments. Auf dieser Basis stellt es fünf Thesen zur weiteren Ausgestaltung der Energiepartnerschaften vor. Die Auswertung zeigt die Flexibilität des Politikinstruments Energiepartnerschaften. Die Partnerländer sind in hohem Maße divers. Sie beinhalten Vorreiter im Bereich erneuerbare Energien ebenso wie große Erdgas- und Öllieferanten. Die Bundesregierung passt das Politikinstrument der Ausgangslage des Partnerlands an. Die Federführung liegt dabei in Deutschland zumeist im Bundesministerium für Wirtschaft und Energie (BMWi) und in den Partnerländern in der Regel ebenso im Energieministerium. Mit der Umsetzung der Partnerschaften betraut sind die GIZ, adelphi, Navigant und die AHK. Diese Umsetzer unterhalten teilweise auch Sekretariate im Partnerland. Typisch für viele Partnerschaften sind regelmäßige Treffen von Steuerungs- und Arbeitsgruppen. In deren Rahmen werden in einigen Partnerschaften auch andere deutsche Ministerium eingebunden. Zu den strategischen Zielen der Partnerschaften zählen neben der Förderung einer globalen Energiewende Aspekte wie die Stärkung des internationalen Klimaschutzes und die Verbesserung von Exportchancen für deutsche Unternehmen. Konkretisiert wird dies in operativen Zielen wie der Unterstützung des Partnerlands beim Ausbau von erneuerbaren Energien oder der politischen Flankierung von Unternehmensaktivitäten. In ihrer Umsetzung unterscheiden die Partnerschaften sich dabei von Aktivitäten anderer Ministerien im Bereich der bilateralen Energiezusammenarbeit sowie der Außenwirtschaftsförderung im Energiebereich des BMWi. Sie schaffen dabei einen strategischen Mehrwert, indem sie Ressortkommunikation im Bereich internationale Energiewendepolitik ermöglichen, als Dach für internationale Energiewendeaktivitäten dienen und ein Netzwerk für die globale Energiewende aufbauen.

Description: The 2015 agreement setting forth the UN Agenda 2030 for Sustainable Development Goals (SDGs) is an important achievement that poses complex and demanding challenges. To adequately address them, judgments must determine contextually and culturally appropriate balances between independently valuable, but often conflicting targets (Singh et al. 2018). Simultaneously, a global coherence across local and regional actions must be ensured, so that local efforts do not destructively interfere with each other, nor overstep limitations in the resources of the planet (Randers et al. 2018). The Global Sustainability Strategy Forum (GSSF) responds to the fact that, after some 40 years sustainability science has produced many insights, but has not really affected our collective behavior with respect to its impact on the environment. Generally, that is deemed to be the result of lack of communication between scientists and the outside world. But might it be that the present practice of science is in itself deficient in producing results that are useful to implement the changes called for? The Forum was established in 2018 with funding from the VW Foundation to identify and address sustainability challenges at the global to regional scales by bringing together, in week-long work-shops, renowned experts in sustainable development and thought leaders in business, government, and civil society from around the world. Under the patronage of Prof. Dr Rita Süssmuth, former President of the German Bundestag, the first Forum was coordinated by Solène Droy with assistance from Paul Skaloud. Moderated by Ilan Chabay (IASS), Sander van der Leeuw (Arizona State University), Ortwin Renn (IASS), 14 panelists convened in Potsdam (Germany) 4-8 March 2019. Eight main lessons emerged from in-depth discussions and reflections towards the end of the forum. They capture some of the main approaches deemed as necessary for science and society to counter patterns and trends of unsustainability and are outlined in this paper. The results were subsequently discussed at the Inland Department of the Office of the German Federal President, addressing fundamental challenges rarely discussed directly at such a high political level. Discussion ranged from tensions between the complexity of the issues and the urgency of the challenges, such as societal acceptance of change, and on the emerging role for compelling plausible visions to inspire and guide sustainability transformation. The expert panel will expand to include decision-makers from business, politics, and civil society to consider strategies for implementation within regional and sectoral contexts. The approach the GSSF develops draws upon indicators and other information to create evidence-informed expert judgments on strategies for implementation of socially just transitions toward sustainable futures at multiple spatial and temporal scales. Of course, the changes required include strengthening and expanding dialogues between scientists, policy makers, business, and civil society; unbiased consideration of diverse sources of knowledge; the substantial refocus of education in an effort to make the central ideas accessible across all ages and segments of society. But that is not enough – the focus of sustainability science itself must be changed to deal with the core issues regarding our current societies’ impact on the environment.

Description: Arctic stakeholders are faced with uncertainty as to the future development of social, political, economic, and environmental conditions, not least due to the ongoing transformations inflicted by climate change. In Blue-Action, the case study focusing on “Yamal 2040: Scenarios for the Russian Arctic” (CS5) has employed a specific co-design and engagement methodology to support stakeholders of one particular region in the Arctic, the Yamal-Nenets Autonomous Okrug (YNAO) in Russia, to respond to this situation of general uncertainty, to develop forward-looking scenarios to better understand the risks and opportunities associated with future transformations in the Arctic. This methodology is the Foresight Exercise. The Foresight Exercise was conducted in the form of a series of three international workshops over 10 months between late 2017 and late 2018. The result thereof were three scenarios for the possible futures of the YNAO, which were co‐designed by stakeholders participating in the workshops and representing environmental NGOs, indigenous peoples’ organisations, business, media, policy‐makers, representatives oflocal communities, and scientists from the natural and social sciences. Results of the workshops were presented in the Blue‐Action deliverables D5.20, D5.21, and D5.22. This present deliverable takes stock of the Foresight Exercise from the perspective of the stakeholder engagement methodology.

Description: On 27 January 2019, the research group CO2 Utilisation Strategies and Society at the Institute for Advanced Sustainability Studies (IASS) hosted the International Round Table “Contextualising Carbon Dioxide Utilisation – International Policy Perspectives on CCU Technologies”. The Round Table on CO2 Utilisation is a series of events, initiated, organised by and held at the IASS in Pots-dam. First started in 2014, it is now an established series that provides an occasion for the profes-sional community involved with the development of CCU technologies to debate and engage with a broad range of societal stakeholders. Framed by two presentations about the United Nations’ Sustainable Development Goals (SDG) and CCU technologies' possible contribution to their delivery, the one-day event consisted of three ses-sions. The sessions were structured according to global regions and focused first on selected coun-tries in Europe (Finland, France, Germany), then on overarching European perspectives and eventu-ally took on a non-European perspective with presentations from China and the United States. Actors in the field of CCU technologies as well as funding agencies and other organisations ascribe the potential to contribute to ecologic, environmental and societal objectives to CCU technologies. Such objectives may be part of the SDGs and other policy targets. Except for further technical de-velopment, the extent of this contribution largely depends on political support with regard to ecolog-ic aspects as well as economic incentives. In order to unfold their full sustainability potential, CCU technologies need a supportive regulatory and policy framework on a European and international level today, and require more tailored support in the future. On either level, specific risks need to be monitored and considered in policy decisions.

Description: Après plus d‘une décennie de délibérations informelles, les États aux Nations unies (ONU) négocient actuellement un „instrument international juridiquement contraignant sur la conservation et l’utilisation durable de la biodiversité marine des zones situées au-delà des limites de la juridiction nationale“ („Accord BZAJN“). Les négociations visent à renforcer le cadre juridique international pour la protection et la gestion de l‘océan pour combler les lacunes du cadre actuel et en s‘appuyant sur les obligations existantes dans le cadre de la Convention des Nations unies sur le droit de la mer (CNUDM) à coopérer pour protéger et préserver le milieu marin et la conservation des ressources marines vivantes. Cette note d‘information explore la manière comment la gestion écosystémique (EBM, pour son acronyme en anglais) dans les zones marines situées au-delà de la juridiction nationale (ZAJN) peut être avancée au niveau régional et comment l‘accord BZAJN peut s‘appuyer sur l‘expérience d‘autres accords juridiquement contraignants pour renforcer la coopération, la coordination et la cohérence regional. À cette fin, cinq éléments de base sont identifiés: 1. Un organe mondial efficace, tel qu‘une conférence des parties, capable de prendre des décisions et d‘adopter des recommandations; 2. Une série de mécanismes régionaux pour l‘élaboration et la coordination intégrées des politiques; 3. Des mécanismes consultatifs efficaces en matière de science et de politique; 4. Des obligations et des principes environnementaux généraux; et 5. Des principes opérationnels pour assurer une bonne gouvernance. Un examen de l‘avant-projet de l‘accord BZAJN de la présidente actuelle met en évidence les points sur lesquels le texte pourrait être renforcé pour faire progresser la gestion écosystémique. En particulier, l‘accord BZAJN pourrait s‘inspirer à partir d‘une série d‘instruments existants et d‘élaborer des obligations spécifiques pour: coopérer à promouvoir la conservation in-situ des écosystèmes et habitats naturels; intégrer la biodiversité dans tous les organes et processus décisionnels; et renforcer la coopération régionale en soutenant institutions existantes et en créant des des plateformes de coopération intersectoriel.

Description: Das vorliegende Papier „Beirätedialog 2019: Empfehlungen zur Weiterentwicklung der Deutschen Nachhaltigkeitsstrategie 2020“ stellt die zentralen Ergebnisse des Beirätedialogs 2019 vor. Es fasst die Ergebnisse und Empfehlungen aus der Dialogveranstaltung 2019 zusammen (S. 6-8.) und präsentiert die individuellen Beiträge und Empfehlungen für die 2020 anstehende Weiterentwicklung der Deutschen Nachhaltigkeitsstrategie (S. 8-57), welche von dreizehn der fünfzehn Teilnehmenden im Nachtrag zum Dialogtreffen 2019 eingereicht wurden.

Description: Die Deutsche Nachhaltigkeitsstrategie (DNS) wurde 2002 erstmals von der Bundesregierung vorgelegt. Seit der Überarbeitung von 20161 ist die Strategie an den Sustainable Development Goals (SDGs) der Vereinten Nationen ausgerichtet. Die DNS legt dar, mit welchen Mitteln die Bundesregierung zur Erreichung der SDGs beitragen will. Die aktuelle Fassung der Strategie stammt von 20182. Die nächste grundlegende Weiterentwicklung der Strategie steht 2020 an. Um möglichst viele Perspektiven und Expertise in die Weiterentwicklung der Strategie einfließen zu lassen, organisiert die Bundesregierung – wie auch schon für vorherige Überarbeitungen – ein gesamtgesellschaftliches Konsultationsverfahren. Unter anderem mit drei Regionalkonferenzen, bei denen im Dialog Beiträge von Bürger*innen und Gesellschaftsvertreter*innen gesammelt werden. Wissenschaftliche Beiträge wurden über die bisherigen gesamtgesellschaftlichen Konsultationsverfahren nur sehr wenige eingebracht. Um die Stimme der Wissenschaft diesmal stärker und systematisch einzubringen, hat die Wissenschaftsplattform Nachhaltigkeit 2030 (wpn2030) eine eigenständige wissenschaftliche Konsultation zu Weiterentwicklung der Deutschen Nachhaltigkeitsstrategie aufgesetzt. Unter dem Titel „Eine Frage der Wissenschaft: Die Deutsche Nachhaltigkeitsstrategie auf dem Prüfstand“ und anhand von sieben Leitfragen waren Wissenschaftler*innen aller Fachrichtungen eingeladen, ihre Erkenntnisse, Vorschläge, Ideen und Empfehlungen online für die Überarbeitung der Strategie einzubringen. Laufzeit des Prozesses war von Mai bis August 2019, insgesamt flossen 93 Beiträge ein.

Description: Nachhaltige Entwicklung in, mit und durch Deutschland ist in hohem Maße von einer Transformation unserer Mobilitäts- und Verkehrssysteme abhängig. Die Wissenschaftsplattform Nachhaltigkeit 2030 als eine zentrale wissenschaftliche Begleiterin Deutscher Nachhaltigkeitspolitik hat das Thema daher mit einer Arbeitsgruppe ins Zentrum ihrer Arbeit gestellt. Das vorliegende Papier beinhaltet wissenschaftlich basierte Empfehlungen für den Staatssekretärsausschuss für nachhaltige Entwicklung für die Förderung einer Mobilitäts- und Verkehrswende. Dafür hat die Arbeitsgruppe unter anderem vorliegende wissenschaftliche Studien zu Szenarien einer Verkehrs- und Mobilitätswende in Deutschland ausgewertet und mit beteiligten Wissenschaftler*innen diskutiert. Zudem hat sich die Arbeitsgruppe in mehreren Schritten mit Vertreter*innen aus Mobilitätspraxis, Politik und Zivilgesellschaft ausgetauscht – unter anderem in Fachgesprächen und einem Trialog – und dabei Chancen und Herausforderungen von Maßnahmen aus unterschiedlichen Perspektiven beleuchtet. Ergebnis sind fünf grundlegende politische Empfehlungen, mit jeweils konkretisierenden Vertiefungen.

Description: New biostratigraphical, geochemical, and magnetic evidence is synthesized with IODP Expedition 352 shipboard results to understand the sedimentary and tectono-magmatic development of the Izu–Bonin outer forearc region. The oceanic basement of the Izu–Bonin forearc was created by supra-subduction zone seafloor spreading during early Eocene (c. 50–51 Ma). Seafloor spreading created an irregular seafloor topography on which talus locally accumulated. Oxide-rich sediments accumulated above the igneous basement by mixing of hydrothermal and pelagic sediment. Basaltic volcanism was followed by a hiatus of up to 15 million years as a result of topographic isolation or sediment bypassing. Variably tuffaceous deep-sea sediments were deposited during Oligocene to early Miocene and from mid-Miocene to Pleistocene. The sediments ponded into extensional fault-controlled basins, whereas condensed sediments accumulated on a local basement high. Oligocene nannofossil ooze accumulated together with felsic tuff that was mainly derived from the nearby Izu–Bonin arc. Accumulation of radiolarian-bearing mud, silty clay, and hydrogenous metal oxides beneath the carbonate compensation depth (CCD) characterized the early Miocene, followed by middle Miocene–Pleistocene increased carbonate preservation, deepened CCD and tephra input from both the oceanic Izu–Bonin arc and the continental margin Honshu arc. The Izu–Bonin forearc basement formed in a near-equatorial setting, with late Mesozoic arc remnants to the west. Subduction-initiation magmatism is likely to have taken place near a pre-existing continent–oceanic crust boundary. The Izu–Bonin arc migrated northward and clockwise to collide with Honshu by early Miocene, strongly influencing regional sedimentation.

Description: The fluttering shearwater (Puffinus gavia) is an abundant seabird endemic to breeding colonies in northern and central New Zealand. The species remains poorly studied, and here we present the first study to examine its breeding biology in detail. Fluttering shearwater nests were monitored daily from laying in September 2015 to fledging in January 2016 on Burgess Island (Mokohinau Islands group) in the outer Hauraki Gulf, northern New Zealand. Burrows were generally simple and non-branched. Eggs were laid over a period of 39 days with laying peaking 12th September. Incubation was 50 ± 3.7 days and chicks fledged after an average of 74 ± 4.3 days, from late December to the end of January. Chick development corresponds to the pattern observed for other Procellariiformes, gaining body mass rapidly to a maximum of 115% of adult mass, and then losing weight until fledging. Chicks were fed most nights throughout chick-rearing, indicating adult birds have access to a stable food supply close to the colony. Breeding success was 63.8% and similar to other Puffinus species. This study provides baseline biological data for a poorly studied, yet common, New Zealand endemics seabird. The obtained new information will allow for further ecological investigations and improved conservation management for the species

Description: Glyoxalase is one of two enzymes of the glyoxalase detoxification system against methylglyoxal and other aldehydes, the metabolites derived from glycolysis. The glyoxalase system is found almost in all living organisms: bacteria, protozoa, plants, and animals, including humans, and is related to the class of ‘life essential proteins’. The enzyme belongs to the expanded Glyoxalase/Bleomycin resistance protein/Dioxygenase superfamily. At present the GenBank contains about 700 of amino acid sequences of this enzyme type, and the Protein Data Bank includes dozens of spatial structures. We have offered a novel approach for structural identification of glyoxalase I protein family, which is based on the selecting of basic representative proteins with known structures. On this basis, six new subfamilies of these enzymes have been derived. Most populated subfamilies A1 and A2 were based on representative human Homo sapiens and bacterial Escherichia coli enzymes. We have found that the principle feature, which defines the subfamilies’ structural differences, is conditioned by arrangement of N- and C-domains inside the protein monomer. Finely, we have deduced the structural classification for the glyoxalase I and assigned about 460 protein sequences distributed among six new subfamilies. Structural similarities and specific differences of all the subfamilies have been presented. This approach can be used for structural identification of thousands of the so-called hypothetical proteins with the known PDB structures allowing to identify many of already existing atomic coordinate entrees.

Description: Morphological variability in gorgonians is frequent and commonly associated with habitat variability, often resulting in segregated morphotypes. Paramuricea macrospina is an endemic Mediterranean gorgonian species found on rocky bottoms between 40 and 160 m depth and has recently been reported as one of the most abundant species in continental shelf and shelf edge environments. Three different chromatic forms of P. macrospina were observed in the Menorca Channel: a yellow form and a light purple form occurring on maërl beds of the continental shelf, and a dark purple form occurring on rocky substrates of the shelf edge. The objective of the present work is to verify if these P. macrospina forms may represent distinct taxonomic units by analysing differences in colony morphology and sclerite size and shape of the three chromatic forms. No significant differences were found in colony shape, suggesting that environmental variability between the continental shelf and the shelf edge is not influential enough to significantly alter colony morphology. Significant differences in sclerite size and shape were found amongst all forms, suggesting that sclerites may be influenced by environmental conditions. However, the co-occurrence of the yellow and light purple forms side by side on the continental shelf may indicate a certain degree of genetic differentiation.

Description: The feeding habits of two sympatric squid species, Uroteuthis (Photololigo) chinensis and Uroteuthis (Photololigo) duvaucelii from the southwestern Gulf of Thailand were studied. They fed on low numbers of food types (AF) and had a low diet breadth; 1.18 and 0.01 for U. (P.) chinensis and 1.49 and 0.05 for U. (P.) duvaucelii, respectively. Three major prey types (fishes, crustaceans and molluscs) were always detected and cannibalism was observed. Fish was the greatest contributor to the diet of both species, contributing 89.5% for U. (P.) chinensis and 69.9% for U. (P.) duvaucelii. Fish size significantly affected fullness index (FL) and AF for U. (P.) chinensis (P 〈 0.001) and U. (P.) duvaucelii (P 〈 0.001). Depth affected the FL of U. (P.) chinensis (P 〈 0.001) but not of U. (P.) duvaucelii (P 〉 0.05). Maturity stages of both male and female U. (P.) chinensis influenced FL (male: P 〈 0.001; female: P 〈 0.05) and AF (male: P 〈 0.05; female: P 〈 0.01). The FL of squid from cast nets was higher than those from trawls. The multivariate results showed dietary grouping between size classes of both species.

Description: Indian squid, Uroteuthis (Photololigo) duvaucelii (Loliginidae) constitute an important component of the inshore cephalopod fisheries along the eastern Arabian Sea. Local environmental variation plays an important role in species–environment interactions in neritic squids, which inhabit nearshore/coastal waters. Such ‘active’ and ‘passive’ responses of squids to environmental changes is crucial in understanding their relationships and influence on the biological processes, distribution and abundance of the fast-growing short-lived coastal loliginids. The empirical relationship between squid abundance and the variability in rainfall and sea surface temperature (SST) were explored in a tropical monsoon fishery. Monthly catch rates (catch per fishing hour) of squids in commercial trawl during 1987–2009 were used as the abundance index. Linear regression models with ARIMA errors were fitted with catch per unit hour time series as dependent variable and rainfall and SST as exogenous variables. While rainfall was observed to have a negative effect on squid abundance, the SST recorded a positive impact. ARIMA models provided satisfactory fit to observed data and forecast of 22 months. Given that the squid life-cycle is a function of their environment, this result is relevant in forecasting squid biomass for the management of tropical monsoon fisheries.

Description: The distribution pattern of purpleback flying squid and the relationship between its abundance and environmental variables in the south-eastern Arabian Sea were analysed using a geographical information system (GIS) and a generalised additive model (GAM). Highest abundances were observed during December and January within 10 and 13°N and 71 and 72°E around the Lakshadweep Islands. The mean abundance in the area was 4.21 tonnes/km2 and the maximum sustainable yield (MSY) was estimated as 0.63 million tonnes. GAM indicated that very high squid abundance was associated with low values of dissolved oxygen (6.01–6.27 mg/L), sea surface temperature (28.03–28.62°C), pH (7.75–8.56), salinity (30.42–34.48 psu), chlorophyll-a (0.4–0.6 mg/m3), zooplankton biomass (0.23–0.64 mL/m3), and shallow 20°C isotherm (101.2–134.7 m) and mixed layer depth (17.8–29.8 m). As a carnivore from paralarval stages, S. oualaniensis depends on secondary and tertiary production to sustain its population for which primary production is used up. In the tropical Arabian Sea where temperature differences are not so pronounced, S. oualaniensis distribution was found to be related to a low but very narrow sea surface temperature (SST) band. There is sufficient fishable biomass in the area to possibly launch a new targeted oceanic squid fishery from the western seaboard of India.

Description: The environmental system of the northern Nordic Seas is very sensitive to oceanographic and climatic changes at the contact of cold Arctic and warmer North Atlantic waters. These contrasts are reflected in the associations of marine microorganisms and archived in the bottom sediments. A microfossil study (diatoms, coccoliths) of late Holocene sediments in core MSM5/5-712-1 from the eastern Fram Strait provides a better understanding of marine ecosystems and palaeoenvironments during Arctic warming events of the last two millennia. Indicative diatom species and groups of species revealed a high variability of sea-surface conditions. Based on the diatom distribution, three warming periods could be detected, corresponding to the time intervals of 0 to 440 CE (the later part of the Roman Warm Period), 1200 to1420 CE (the final part of the Medieval Climate Anomaly) and 1730 CE to present (including the Recent Warming). The various micropalaeontological proxies used in this study and other publications describe the Roman Warm Period and, especially, the Recent Warming as the most pronounced warm events in the area during the last 2000 years. A comparison of data from the different microfossil groups, indicators of sea-surface and subsurface conditions, reveals variable, complicated and non-simultaneous palaeoenvironmental signals within the warm periods. This can potentially be explained by changes in the surface/subsurface water structure during the events (variations in the cold/warm water advection, stratification, availability of nutrients, seasonal succession of bioproductivity, etc.), which are reflected by changes in the microplankton communities.

Description: Microplastic contamination of aquatic environments has become an increasingly alarming problem. These, defined as particles 〈5 mm, are mostly formed due to the cracking and embrittlement of larger plastic particles. Recent reports show that the increasing presence of microplastics in the environment could have significant deleterious consequences over the health of marine organisms, but also across the food chain. Herein, we have studied the effects of artificial seawater on polyethylene (PE)-based beads by exposing them up to eight weeks to saltwater in stirred batch reactors in the dark and examined the structural and morphological changes these endured. Electron microscopy observations showed that artificial seawater induces severe microcracking of the pellets' surfaces. Additionally, Fourier transform infrared spectroscopy (FTIR) analyses evidenced the formation of oxidized groups whenever these particles were exposed to water and an increase in organic matter content of the waters in which the pellets were kept was evidenced by Raman spectroscopy. There were also noticeable consequences in the thermal stability of the polyethylene pellets, as determined by thermogravimetric studies (TGA). Furthermore, the parallel exposure of polyethylene pellets to UV radiation yielded less pronounced effects, thus underscoring its lower preponderance in the degradation of this material. These results highlight the importance of determining the mechanisms of degradation of microplastics in marine settings and what the implications may be for the environment. Overall, the herein presented results show that a relatively short period of time of accelerated exposure can yield quantifiable chemical and physical impacts on the structural and morphological characteristics of PE pellets.

Description: A large number of remarkable studies on the secondary metabolites of fungi have been conducted in recent years. This review gives an overview of one hundred and sixty-seven molecules with novel skeletons and their bioactivities that have been reported in seventy-nine articles published from 2013 to 2017. Our statistical data showed that endophytic fungi and marine-derived fungi are the major sources of novel bioactive secondary metabolites.

Description: As an important DNA source, herbarium specimens have been widely used in plant phylogenetics due to their easy accessibility and richness. However, contamination is a constant risk owing to low quality and/or quantity of DNA extracted from old samples. The inclusion of contaminant sequences can mislead phylogenetic reconstruction, and thereby affect subsequent analyses, such as divergence time estimates and biogeographic inferences. To employ appropriately herbarium specimens in plant phylogenetics, we outline here several suggestions regarding DNA extraction, PCR amplification and sequencing. We hope that these suggestions will serve as a guide for researchers using herbarium specimens in plant phylogenetics and help them identify from the early steps potential contaminant sequences from other plants or other organisms.

Description: Iron is required for microbial growth and proliferation. To survive in low-iron environments, some microorganisms secrete ferric iron chelators called siderophores. Siderophore biosynthesis occurs via two pathways: the non-ribosomal peptide synthetase (NRPS) pathway and the NRPS-independent siderophore (NIS) synthetase pathway. NIS enzymes function by adenylating a carboxylic acid substrate, typically citrate, or a derivative, followed by nucleophilic capture of an amine or alcohol and displacement of a citryl intermediate. In this review, we summarize recent advances in NIS biochemistry with a particular focus on structural biology and confirm the classification of NIS enzymes into Types A, A', B, and C based on substrate specificity. Based on a phylogenetic analysis, we also propose a new subclass of NIS enzymes, Type C', responsible for dimerization and macrocyclization of complex and substituted amine or amide intermediates. Finally, we describe the role of NIS enzymes in virulence of pathogenic microbes and discuss NIS inhibitors as potential anti-microbial agents.

Description: Hydrothermal precipitates and hydrothermal alteration products could record important information about temporal variations of seafloor hydrothermal systems. Geochemistry, mineralogy, and microscopic features of three pumice samples (T3-1, T3-2, and T3-3) near the Iheya North hydrothermal field were analyzed in this article. The results show that T3-3 sample has undergone at least two-stage influences by hydrothermal fluids. In the first stage, pure amorphous silica from hydrothermal fluid precipitated in the vesicles of all three T3 samples as a result of conductive cooling and fluid–seawater mixing. The precipitation temperatures according to oxygen isotope thermometer are approximately 13–21°C. In the second stage, T3-3 pumice underwent low-temperature hydrothermal alteration, during which the amorphous silica precipitates were redissolved, together resulting in losses of FeO and SiO2 and gains of MgO, Pb, Zn, and Cu. Furthermore, ferruginous filamentous silica, which might be related to activities of Fe-oxidizing bacteria, was formed in the altered pumice. The transformation from pure amorphous silica precipitation to redissolution of the silica in T3-3 pumice might indicate a rise of temperature and/or decrease in silica concentrations in hydrothermal fluids, implying a changing hydrothermal environment.

Description: We propose a geochemical parameter, “metal flux” in evaluating hydrogenetic Co-rich ferromanganese crust deposits in the Pacific seamount area, that is based on physical, chemical, and geological characterization of the integrated growth piles of crusts. We calculated the metal flux for fifteen sites from different depths ranging between 900-6000m from different seamounts. The secular and areal variations of metal flux indicate a strong geological controls, and also can be a reliable tool for estimating an economic potential of the crusts. The Co flux decreases with increasing water depth, followed by almost constant flux of Ni and Mn. The Al and Fe fluxes vary with regions, indicating higher values in the western regions near the island arc probably related to a supply from the Asian continents. The results imply that Co, a redox sensitive metal element, is controlled by redox conditions of seawater, while Fe and Al are by terrigenous input. The metal flux reflects global and regional conditions and controls the compositional diversity of metals, thus consequently, the parameter can be a reliable powerful tool to estimate or single out more potential areas.

Description: This report is intended to provide a review of the relevant governance frameworks currently in place for the management of high seas biodiversity in these regions. The report uses the issues under discussion in the ongoing negotiations for a new legally binding BBNJ agreement under the United Nations, as well as selected Sustainable Development Goal (SDG) 14 targets, as a lens through which to assess progress towards conservation and sustainable use.

Description: The series of the Yamal 2040 Scenario Workshops is a part of the international research project “BlueAction – Arctic Impact on Weather and Climate” funded through the European Union’s Horizon 2020 Programme. This project aims to evaluate the impact of a changing Arctic on northern hemisphere weather and climate. Blue-Action brings together 120 experts from over 40 organizations in 17 countries most of whom are climate scientists dealing with improvement of existing and development of new techniques that will enable robust and reliable forecasting of weather and hazardous climate events in the Arctic and over the northern hemisphere. However, Blue-Action is not limited to natural science’ goals alone. As a final result, the project aims to improve the safety and wellbeing of people in the Arctic and across the northern hemisphere by reducing risks associated with a changing climate and Arctic operations like resource exploitation, and to support evidence-based decision-making by policymakers worldwide. To achieve this, Blue- Action takes a transdisciplinary approach, bridging scientific understandings of Arctic climate, weather and risk management research with key rights- and stakeholder knowledge. This is being done within the project’s Work Package 5 “Developing and Valuing Climate Services”, which consists of a set of case studies that bring scientists together with stakeholders to co-develop products that “translate” the model outputs and improved modelling skill developed in other work packages into societal- and sectorrelevant products. Our case study in the Blue-Action project develops a study of the impact of the Arctic changes on resource development in the Russian Arctic with the goal of improving stakeholders’ capacity to adapt to these changes. The Yamal 2040 Scenario Workshop series is at the core of the case study. The work carried out in this deliverable is a desk study producing a map of stakeholder groups involved in oil and gas development on the Yamal-Nenets Autonomous Okrug (YNAO). This study is part of the preparatory work for the scenario exercise conducted in cooperation with various stakeholder groups active in or affected by oil and gas development in YNAO.

Description: Qu'il s'agisse d'énergie propre, de production durable ou de réduction de la pauvreté, les idées et analyses sur les défis du développement durable ne manquent pas. Pourtant, nous faisons encore trop peu de progrès pour atteindre un état de durabilité. Comment mieux mettre en oeuvre nos connaissances et lier les défis du développement durable, la science et les réponses politiques? Tel est le thème du Global Sustainability Strategy Forum, qui, tous les deux ans, réunira une quinzaine d'éminents experts internationaux sur la durabilité pendant une semaine, et pour la première fois du 4 au 8 mars 2019 à Potsdam.

Description: From clean energy to sustainable production and the fight against poverty – insights into the many challenges of sustainable development are not in short supply. But despite the wealth of knowledge available to policymakers, little progress has been made in the transformation towards a sustainable future. How can we bring our knowledge to bear more effectively? This question underpins the Global Sustainability Strategy Forum, which will bring together 15 leading international experts for a week-long retreat in Potsdam every two years, beginning on 4 – 8 March 2019.

In addition to discussing the technical details of the cable conductor, electrical insulation, and grid connections, it outlines the environmental benefits and future implementation challenges of this new technology. The concluding remarks include recommendations for industry and policymakers.

Description: Grundlegende gesellschaftliche Fragen, komplexe systemische Risiken, umfassende Zukunftsentwürfe - sie finden nach Meinung vieler Beobachter keinen angemessenen Platz in der politischen Auseinandersetzung und noch weniger im Handeln von Regierung und politischer Administration. Das ist das Problem, von dem hier die Rede sein soll. Es gilt daher Herausforderungen mittel- und langfristiger Art gezielter und systematischer zu Themen politischer Strategieentwicklung zu machen - das ist die Aufgabe. Die Frage ist: Welche Formen politisch-administrativer Organisation und Vorgehensweise sind geeignet mit solchen Herausforderungen umzugehen und nachhaltige Lösungsansätze zu erarbeiten? Ausgangsüberlegung hier ist es, dass über offene und innovative Suchprozesse effiziente und effektive Steuerungs- und Regierungsstrukturen identifiziert und initiiert werden können und sollten. Der vorliegende Beitrag begründet und skizziert einen Vorschlag für einen solchen offenen Suchprozess innerhalb des deutschen Regierungshandelns auf Bundesebene. Vorgeschlagen wird die Einrichtung eines „Government Innovation Lab(oratorium)s“ - als eine von mehreren Ressorts getragene Arbeitseinheit mit dem Auftrag, innovative abteilungs- und ressortübergreifende Kommunikations- und Kooperationsformen zu initiieren. "Lab" steht für den experimentellen und kollaborativen Ansatz, Innovation bezieht sich auf Organisation und Verfahren, Government adressiert den Innovationsimpuls in Richtung auf das Betriebssystem des Regierens selbst. Der Vorschlag für ein solches „Lab“ ist bewusst als ein experimenteller Impuls für den Kreis der Bundesministerien und als Stärkung ressortübergreifender Koordination zu verstehen. Das „Lab“ fokussiert auf Anstöße für organisatorische Innovationen in frühen Phasen der Themenfindung und -strukturierung im politisch-administrativen Umgang mit neuen und noch schwer greifbaren Problemlagen. Der Vorschlag ist als Experiment auf starke Promotoren und unterschiedliche Anknüpfungspunkte angewiesen, setzt er doch an der vielfach als neuralgisch – d.h. schmerzhaft und kaum lösbar - wahrgenommenen Frage an, wie auf Seiten der Exektuve Komplexität zu organisieren sei. Das hier vorgelegte Papier kann und soll nicht konkrete Optionen für die einzelnen Umsetzungs-schritte, die Organisation, Steuerung und Vorgehensweise entwerfen, sondern bietet für weitere Sondierungsgespräche im Raum von Experten, Promotoren und Entscheidern eine Gesprächs- und Diskussionsgrundlage. Am Beginn steht die Frage des Umgangs mit komplexen Herausforderungen im Politik- bzw. Regierungsbetrieb und die zentrale Rolle von Kommunikation, Kooperation und Koordination für nachhaltige Lösungsansätze (Teil 1). Es folgen Überlegungen zur Anschlussfähigkeit von Innovationen im Regierungsbetrieb mit Blick auf eine Stärkung ressortübergreifender Ko-ordination (Teil 2). Erläutert werden auf dieser Basis Grundidee und einzelne Stränge des angedachten „Government Innovation Lab“ (Teil 3), der Beitrag endet mit einem kurzen Ausblick (Teil 4). Der Beitrag entstand unter anderem vor dem beruflichen Hintergrund des Autors in der Organisationsberatung und seit 2007 als Referatsleiter im Bundesumweltministerium. Der Beitrag gibt jedoch ausschließlich persönliche Überlegungen und Einschätzungen des Autors wieder.

Description: Bei der Realisierung einer nachhaltigen Lebensweise kommt der Wirtschaft zentrale Bedeutung zu. Dies umfasst sowohl die Entwicklung eines entsprechenden regulatorischen Rahmens als auch die Förderung und Etablierung nachhaltiger Unternehmenspraktiken, die ökologische und soziale Be-lange integrieren. Branchenübergreifend ist dabei eine Auseinandersetzung zwischen ökofairem und konventionellem Wirtschaften zu beobachten, von der Agrarwirtschaft, über Chemie und Automo-bilindustrie, bis zur Energiewirtschaft – um die besonders umstrittenen Branchen zu nennen. In Wis-senschaft und Öffentlichkeit wird über die Machbarkeit von ökofairem Wirtschaften im Wettbewerb mit vorrangig profitgetriebenen Konkurrenten diskutiert, wobei der Fokus meist auf einer Analyse der Geschäftspraktiken liegt. Der vorliegende Artikel wendet sich dem bisher meist wenig beleuchte-ten Aspekt der mentalen Voraussetzungen öko-fairen Wirtschaftens zu und beschäftigt sich mit der Frage, welche Einstellungen und Werten den Entscheidungen von ökofairen UnternehmerInnen vorausgehen und diese prägend beeinflussen. Dabei zeigt die Auswertung von 35 qualitativen Interviews mit GeschäftsführerInnen und InhaberIn-nen ökofairer Betriebe, dass sie – unterschiedlich ausgeprägt - Verantwortung übernehmen für die Belange aller Berührungsgruppen ihres Unternehmens, von KundInnen, über MitarbeiterInnen, Lie-ferantInnen, das lokale Umfeld, die Gesellschaft und die Natur. Sie definieren Nachhaltigkeit als zukunftsorientiertes Konzept für die Wirtschaft. Ihre Anstrengungen für nachhaltige Unternehmens-praxis werden von vielen nicht als Belastung empfunden, sondern erfüllen sie mit Freude. Unter-nehmensintern leben sie es vor, setzen die Ressourcen des Unternehmens dafür ein und verstetigen den Kurs mit Regelwerken, Nachhaltigkeitsberichten und Managementsystemen. Die Vorteile des ökofairen Wirtschaftens werden aus den Angaben der Befragten deutlich. Diese Unternehmen führen den lebenden Beweis, dass eine werte-orientierte, ethisch motivierte Wirtschaftspraxis im Wettbe-werb bestehen kann. Im Anschluss an die Darstellung der Interview-Ergebnisse werden die Stufen der Entwicklung des Bewusstseins, die in der Studie erkennbar wurden, nachgezeichnet und mit dem Konzept des Homo Oeconomicus verglichen. Es wird argumentiert, dass es erforderlich ist, das Verständnis des Homo Oeconomicus zu überwinden, um die ökologischen und sozialen Herausforderungen des Anthropo-zäns bewältigen zu können. Die Weiterentwicklung der ethischen Reife der Menschheit wird als die grundlegende Voraussetzung der Veränderung beschrieben. Danach werden die Möglichkeiten der Verbreitung von fortschrittlichen Denkformen in Wirtschaft, Gesellschaft und Staat erörtert und es wird eine Perspektive zur Veränderung aufgezeigt, die in Ansätzen bereits existiert.

Description: Die Studie arbeitet gesellschaftliche Strukturdeterminanten und -dynamiken sowie Frames, Bedingungsverhältnisse, Trade-offs, Kopplungen und Eigendynamiken von Energiewende und – in deutlich verkürzter Form – von Energiekonflikten und von nachhaltiger Entwicklung heraus, thematisiert die Zusammenhänge dieser drei Sphären, und versucht auf dieser Grundlage, Entwicklungsmuster und Erfolgschancen der Energiewende abzuschätzen. Als eine soziotechnische Transformation verlangt die Energiewende die Realisierung eine Vielzahl von Maßnahmen in praktisch allen Teilsystemen der Gesellschaft, die ihrerseits vielfältige Konflikte generieren. Von daher ist die Energiewende in ihrer Entwicklung nicht akteurspezifisch steuerbar und eine erwünschte konsistente, ihre Nachhaltigkeit gewährleistende, produktive Konflikte nutzende und unproduktive Konflikte vermeidende Energiewendepolitik allenfalls ansatzweise zu erwarten. Prinzipiell ist eine die Energiewende konsequent vorantreibende Interaktionsdynamik der sie prägenden Einflussfaktoren zwar denkbar und möglich, in der Praxis ist hingegen eine die Energiewende eher erratisch antreibende Interaktionsdynamik aus einer Kombination von für sie vorteilhaften und nachteiligen Einflussfaktoren zu beobachten.

Description: Ob saubere Energie, nachhaltige Produktion oder Armutsbekämpfung – an Ideen und Erkenntnissen zu den Herausforderungen nachhaltiger Entwicklung mangelt es nicht. Dennoch machen wir beim Wandel zur Nachhaltigkeit zu wenig Fortschritte. Wie können wir unser Wissen besser umsetzen? Das ist das Thema des Global Sustainability Strategy Forum, das alle zwei Jahre rund 15 führende internationale Nachhaltigkeitsexpertinnen und -experten zu einer einwöchigen Klausur zusammenbringen wird, zum ersten Mal vom 4. bis 8. März 2019 in Potsdam.

Description: Die Förderung des Energieträgers Braunkohle im Tagebau ist mit erheblichen Eingriffen in Landschaft, Wasserhaushalt und Siedlungsstrukturen verbunden. Es wird Milliarden kosten, die vom Bergbau beanspruchten Gebiete wieder nutzbar zu machen und alle Folgeschäden zu beheben. Die Finanzierung und Durchführung der Maßnahmen zur Wiedernutzbarmachung der Tagebaue liegt nach Bundesberggesetz in der Verantwortung der Tagebaubetreiber.

Description: In order to sketch the possibility space for the future setup of the International Monetary System (IMS), this paper develops four different scenarios that outline potential outcomes of the IMS’s evolution by 2040. These scenarios derive from the analytical exercise of adopting a Money View perspective of today’s institutional shape of the IMS. The paper argues that the IMS’s current setup crucially relies on the supply of US Dollar-denominated credit money forms issued by private and public institutions outside the United States—through Eurodollar deposits, central bank swaps as well as ‘shadow money forms’ created by non-banks such as overnight repurchase agreements, money market fund shares and foreign exchange swaps. As this ‘realm’ of offshore dollar creation forms the heart of the present IMS, the four scenarios project potential institutional developments in coming decades following different trajectories. The Continued Dollar Hegemony scenario depicts the sustained dominance of private international money creation via offshore dollars within the Pax Americana. The Competing Monetary Blocs scenario envisions the US, the EU, and China as three gravitational centers with private international money creation in the blocs’ peripheries via offshore dollars, offshore euros and offshore renminbi. In the International Monetary Federation scenario, countries have created a strong publicly organized IMS, comprising a multilateral framework of one international and several regional clearing unions, based upon Keynes’ ideas for an International Clearing Union. Finally, the International Monetary Anarchy scenario entails the post-crisis emergence of a non-system with a substantial breakdown of public and private international monetary cooperation and creation.

Description: This paper studies the transformation of the International Monetary System (IMS) in the run up to and after the 2007-9 Financial Crisis. Adopting a Money View perspective, it argues that the IMS, in contrast to wide-spread skepticism, does have a system-like quality. This paper understands the IMS as a US-centered hierarchical payments system within which short-term debt instruments are issued as credit money by various public and private financial institutions, in particular central, commercial and shadow banks. With the Fed located at the apex of the IMS, credit money forms denominated in US dollars are located highest up in the hierarchy and trade at par with each other, whilst they typically have fluctuating exchange rates to credit money forms denominated in the units of account of other monetary jurisdictions. From this, the paper argues that the key component of today’s IMS is the ‘realm’ of offshore US dollar creation, which is situated in between US dollar-denominated credit money issued in the US (‘onshore dollars’) and non-US dollar-denominated credit money issued outside the US. In this ‘offshore dollar realm’, non-US financial institutions are able to create international liquidity via US dollar-denominated private credit money outside the US. The paper systematically carves out the post-2008 setup of the offshore dollar realm with a focus on Eurodollar deposits, offshore money market fund shares, foreign exchange swaps and central bank swaps. With the institutional innovations materializing during the 2007-9 Financial Crisis, the IMS is now a public-private hybrid that fully mirrors the onshore US monetary system in the offshore dollar realm.

Description: Este informe demuestra que existe tanto la necesidad como la oportunidad de aumentar la interacción entre los niveles regional y mundial de la gobernanza de los océanos mediante un nuevo acuerdo mundial para la conservación y el uso sostenible de la diversidad biológica marina en las áreas fuera de la jurisdicción nacional (ABNJ, por sus siglas en inglés). En particular, este informe de política tiene por objeto destacar el papel y la contribución de la gobernanza regional y sectorial en elaborar y apuntalar la aplicación de un acuerdo fuerte en alta mar. Los esfuerzos regionales ofrecen lecciones aprendidas, plataformas para el intercambio de datos y conocimientos científicos, mecanismos para convocar a los Estados y las partes interesadas y coordinar los enfoques y medidas regionales para la gestión. Este informe identifica las oportunidades para aumentar la coordinación, la cooperación y la acción entre estos dos niveles en vista de un acuerdo internacional jurídicamente vinculante eficaz en el marco de la Convención de las Naciones Unidas sobre el Derecho del Mar (CONVEMAR).

Description: The paper points out that a “balanced mix” of nuclear, wind and solar will be the most expensive option – unless future nuclear reactors can ramp like current open-cycle gas turbines.

Description: This policy brief demonstrates that there is both a need and opportunity to increase the interplay between the regional and global levels of ocean governance through a new global agreement for the conservation and sustainable use of marine biodiversity in areas beyond national jurisdiction (ABNJ). Particularly, this policy brief aims to highlight the role and contribution of regional and sectoral governance in developing and underpinning the implementation of a strong high seas agreement. Regional efforts offer lessons learned, platforms for scientific data and knowledge exchange, mechanisms for convening states and stakeholders and coordinating regional approaches and measures for management. This policy brief identifies opportunities for how the coordination, cooperation and action between these two levels can be increased in view of an effective international legally binding agreement under the UN Convention on the Law of the Sea (UNCLOS).

Description: Cette note d'information montre qu'il est à la fois nécessaire et possible d'accroître l'interaction entre les niveaux régional et mondial de la gouvernance des océans par le biais d'un nouvel accord mondial pour la conservation et l'utilisation durable de la biodiversité marine dans les zones situées au-delà de la juridiction nationale (BZAJN). Cette note vise en particulier à mettre en évidence le rôle et la contribution de la gouvernance régionale et sectorielle dans l'élaboration et la mise en oeuvre d'un accord efficace sur la haute mer. Les efforts régionaux offrent des enseignements, des plateformes d'échange de données et de connaissances scientifiques, des mécanismes pour réunir les États et les parties prenantes et de coordonner les approches et les mesures régionales de gestion. Cette note d'information identifie les possibilités d'accroître la coordination, la coopération et l'action entre ces deux niveaux en vue d'un accord international juridiquement contraignant efficace dans le cadre de la Convention des Nations unies sur le droit de la mer (CNUDM).

Description: Different studies on the position of the non-indigenous species Neogobius melanostomus within the coastal food web of the Pomeranian Bay (western Baltic) were performed, resulting in a quantitative and qualitative species list of prey organisms found in the stomachs of the invader and an estimation concerning the importance of round goby as prey for different resident predators. It seems that the colonization process is not fully completed yet, but the results reveal that the species is already established in the food web 16 years after the first observation within the study area. The results show that N. melanostomus feed upon a wide range of different resident organisms. While a direct predation effect on native fish species appears rather unlikely, indirect effects such as competition cannot yet be excluded. In addition, our results reveal an ontogenetic diet shift and that the round goby itself already serves as an important prey for piscivorous fish and seabirds. Finally, we formulate different hypotheses based on our results which will require further research.

Description: International Ocean Discovery Program (IODP) Expedition 352 recovered a high-fidelity record of volcanism related to subduction initiation in the Bonin fore-arc. Two sites (U1440 and U1441) located in deep water nearer to the trench recovered basalts and related rocks; two sites (U1439 and U1442) located in shallower water further from the trench recovered boninites and related rocks. Drilling in both areas ended in dolerites inferred to be sheeted intrusive rocks. The basalts apparently erupted immediately after subduction initiation and have compositions similar to those of the most depleted basalts generated by rapid sea-floor spreading at mid-ocean ridges, with little or no slab input. Subsequent melting to generate boninites involved more depleted mantle and hotter and deeper subducted components as subduction progressed and volcanism migrated away from the trench. This volcanic sequence is akin to that recorded by many ophiolites, supporting a direct link between subduction initiation, fore-arc spreading, and ophiolite genesis.

Description: The production of shiga toxin (Stx) is a critical step in the establishment and progress of enterohemorrhagic Escherichia coli (EHEC) infections. The possible release of Stx from dead and dying bacteria, and the risk of resistance development have restricted the usage of antibiotics against EHEC. The chlorinated quaternary ammonium compound, strepthonium A, was isolated from the culture of Streptomyces sp. SBT345 that was cultivated from the Mediterranean sponge Agelas oroides. The structure was elucidated and confirmed by spectroscopic analyses including 1D and 2D NMR, ESI-HRMS, as well as ESI-HRMS2. Strepthonium A follows Lipinski's rule of five with respect to its molecular weight, CLogP values and the number of hydrogen acceptors and donors. Verotoxin ELISA assay demonstrated that Strepthonium A reduced the Stx production in EHEC strain EDL933 at 80 μM concentration without growth inhibition. This study demonstrates the potential of strepthonium A in restraining the production of Stx in EHEC infections.

Description: Land-use dynamic is a major challenge for town and country planners especially in developing countries such as Iran. Iran has been under rapid urban expansion and population growth for past three decades which led to lack of resources, environmental deterioration and haphazard landscape development. In this paper, an attempt has been made to map the urbanization dynamics of Tehran in 40 years based on remote sensing imagery and by means of artificial neural networks. The presented scheme could be taken into consideration when planning initiatives aimed at surveying, monitoring, managing and sustainable development of the territory. Moreover, it can serve the experts in the fields of geography, urban studies and planning as a background for number of geographical analyses.

Description: Current antifouling (AF) technologies are based on the continuous release of biocides into the water, and consequently discharge into the environment. Major efforts to develop more environmentally friendly coatings require efficient testing in laboratory assays, followed by field studies. Barnacles are important fouling organisms worldwide, increasing hydrodynamic drag on ships and damaging coatings on underwater surfaces, and thus are extensively used as models in AF research, mostly in static, laboratory-based systems. Reliable flow-through test assays for the screening of biocide-containing AF paints, however, are rare. Herein, a flow-through bioassay was developed to screen for diverse low-release biocide paints, and to evaluate their effects on pre- and post-settlement traits in barnacles. The assay distinguishes between the effects from direct surface contact and bulk-water effects, which are crucial when developing low-emission AF coatings. This flow-through bioassay adds a new tool for rapid laboratory-based first-stage screening of candidate compounds and novel AF formulations.

Description: IODP Expedition 350 was the first to be drilled in the rear part of the Izu-Bonin, although several sites had been drilled in the arc axis to fore-arc region; the scientific objective was to understand the evolution of the Izu rear arc, by drilling a deep-water volcaniclastic section with a long temporal record (Site U1437). The Izu rear arc is dominated by a series of basaltic to dacitic seamount chains up to ~100-km long roughly perpendicular to the arc front. Dredge samples from these are geochemically distinct from arc front rocks, and drilling was undertaken to understand this arc asymmetry. Site U1437 lies in an ~20-km-wide basin between two rear arc seamount chains, ~90-km west of the arc front, and was drilled to 1804 m below the sea floor (mbsf) with excellent recovery. We expected to drill a volcaniclastic apron, but the section is much more mud-rich than expected (~60%), and the remaining fraction of the section is much finer-grained than predicted from its position within the Izu arc, composed half of ashes/tuffs, and half of lapilli tuffs of fine grain size (clasts 〈3 cm). Volcanic blocks (〉6.4 cm) are only sparsely scattered through the lowermost 25% of the section, and only one igneous unit was encountered, a rhyolite peperite intrusion at ~1390 mbsf. The lowest biostratigaphic datum is at 867 mbsf (~6.5 Ma), the lowest palaeomagnetic datum is at ~1300 mbsf (~9 Ma), and the rhyolite peperite at ~1390 mbsf has yielded a U–Pb zircon concordia intercept age of (13.6 + 1.6/−1.7) Ma. Both arc front and rear arc sources contributed to the fine-grained (distal) tephras of the upper 1320 m, but the coarse-grained (proximal) volcaniclastics in the lowest 25% of the section are geochemically similar to the arc front, suggesting arc asymmetry is not recorded in rocks older than ~13 Ma.

Description: In this opinion paper, we, a group of scientists from environmental-, geo-, ocean- and information science, argue visual data exploration should become a common analytics approach in Earth system science due to its potential for analysis and interpretation of large and complex spatio-temporal data. We discuss the challenges that appear such as synthesis of heterogeneous data from various sources, reducing the amount of information and facilitating multidisciplinary, collaborative research. We argue that to fully exploit the potential of visual data exploration, several bottlenecks and challenges have to be addressed: providing an efficient data management and an integrated modular workflow, developing and applying suitable visual exploration concepts and methods with the help of effective and tailored tools as well as generating and raising the awareness of visual data exploration and education. We are convinced visual data exploration is worth the effort since it significantly facilitates insight into environmental data and derivation of knowledge from it.

Description: A bioassay-guided approach was used to identify defense compounds that are present on the surface of Zostera marina and which inhibit settlement of microfoulers at natural concentrations. Moderately polar eelgrass surface extracts inhibited the settlement of seven marine bacteria and one yeast that originated from non-living substrata. In contrast, five other bacterial strains that had been directly isolated from eelgrass surfaces were all insensitive, which suggested a selective effect of surface metabolites on the microbial communities present on eelgrass. Bioassay-guided isolation of active compounds from the extracts in combination with UPLC-MS and 1H-NMR spectroscopy resulted in the identification of rosmarinic acid, luteolin-7-sulfate and diosmetin-7-sulfate or its isomer chrysoeriol-7-sulfate. All three compounds are nontoxic repellents, as they did not inhibit bacterial growth, but prevented bacterial settlement in a dose-dependent manner. Between 15.6 and 106.8 μg ml−1 of rosmarinic acid were present on the eelgrass surface, enough for half maximal settlement inhibition of bacteria.

Description: The progressive bond breakage of artificially cemented sands induced by shear straining was investigated through conventional isotropically consolidated drained triaxial compression tests. Sand specimens were prepared with a low degree of cementation by adopting a chemical grout. Test results were interpreted in terms of two stress–dilatancy theories for cohesive-frictional materials proposed in literature. The influence of debonding on the stress–dilatancy behaviour of cemented sands was analysed with particular emphasis on the ‘delayed dilatancy’ phenomenon. A bonding degradation curve was determined for each test relating the interparticle cohesion (c) to the magnitude of the total plastic strain vector (εd) and a bond degradation rate factor (Dc) was assessed from each curve. The maximum value of interparticle cohesion (c0) before the onset of bond degradation under shearing was found to correspond with a sharp decrease in the soil stiffness of the specimens. The influence of the effective confining stress (p′c)on both c0 and Dc parameters gathered from each test was also ascertained.

Description: The spatial variations in the elemental and stable carbon, nitrogen, and sulphur isotope composition of bladder wrack (Fucus vesiculosus) growing along the shore line of the semi-enclosed urbanized Kiel Fjord (western Baltic Sea) was investigated at more than 60 sites. The analyses of the carbon-nitrogen-sulphur (CNS) stoichiometry and C and N stable isotope signature of F. vesiculosus displayed substantial differences between the north-western and the south-eastern parts of the Kiel Fjord. Different size classes displayed in part differences in C:N and C:S ratios, and the carbon isotope composition, reflecting the impact of the boundary conditions during growth. Whereas the sulphur isotope composition was controlled by the assimilation of seawater sulphate, the carbon isotope composition reflected the difference in the composition of surface waters. The δ15N values of the organic tissue tend to be an integrated monitor of anthropogenic impacts on the fjord. Results are compared to the composition of surface waters.

Description: This study aimed to differentiate local and migratory spawning groups of the shortfin squid Illex argentinus caught in Brazilian waters using geometric and traditional morphometric methods and size-selective processes. The back-calculated length distributions reconstructed from daily growth increments deposited in the gladius allowed the identification of size-selective processes that may be related to different life history strategies. Landmark analysis on body shape (geometric morphometric) revealed that spawning groups presented significant ontogenetic variations in terms of body outline. In addition, traditional morphometric methods, based on multivariate analysis, associated juveniles of the expected migratory group (large size) and differentiated them from the local group individuals (small size). The changes in form, probably linked to the environmental gradients experienced by individuals throughout ontogeny, were interpreted as adaptations to improve swimming capacity. Migrant individuals have being differentiated from the smaller sizes group by body characteristics (broad fins, elongated and thicker mantle), which may increase the ability to perform long migrations.

Description: We investigated the biogeochemical constituents, microbial communities and functional genes (mcr and dsr) associated with anaerobic methane oxidation and sulfate reduction, and metabolic activities by sulfate reduction in the sulfate–methane transition zone (SMTZ) of gas-hydrate-bearing sediment of the Ulleung Basin in the East Sea. Maxima in the sulfate reduction rate (12.6 nmol cm¡3 d¡1), CO concentration (83 mM), and gene abundances of dsrA (9.1 £ 106 copies cm¡3) and mcrA (11.6 £ 106 copies cm¡3) occurred in the SMTZ. The peaks of CO consistently found in the SMTZ suggested that CO is an intermediate metabolic product related to methane oxidation. Candidate division JS1, the predominant bacterial group that comprised 59.0–63.7% of the 16S rRNA gene sequences, was recognized as an important organic carbon oxidizer. Both Marine Benthic Group D (MBGD) and Marine Benthic Group B (MBGB), which constituted 40.8–52.9 and 10.3–43.9% of the 16S rRNA gene sequences, respectively, were the dominant archaeal groups. Analysis of functional gene diversity revealed that anaerobic methanotroph-1-related phylotypes appeared to be the major CH4 oxidizer, whereas Firmicutes-like group was a predominant sulfate reducer in the 0.8 mbsf in SMTZ with low SO42¡ concentration. Overall results indicated that JS1 and two archaeal groups (MBGB and MBGD) seem to play a significant role in carbon and elements cycles in the gas-hydrate-bearing subsurface sediment of the Ulleung Basin.

Description: Introduction: The combination of growing antimicrobial resistance with a dry pipeline has resulted in infections that can no longer be treated. Specific reasons have led to companies’ exit from the antibacterial space, however recent incentives are spurring interest to reinvigorate the pipeline. Areas covered: This article summarizes the available information on the discovery, developmental, and regulatory challenges in antibacterial development that have led to disinterest in the space, as well as ongoing incentives such as public-private partnerships and streamlined pathways to mend these challenges and bring new antibiotics to patients in need. Expert commentary: Clinicians should not only understand the reasons for the decline in antibiotic development that have resulted in the dry pipeline, but also the ongoing initiatives in place to build an appropriate supply. Doing so will result in greater appreciation and prudent use of these life-saving drugs when they become available.

Description: The Red Sea has been recognized as a unique region to study the effects of ecohydrographic gradients at a basin-wide scale. Its gradient of temperature and salinity relates to the Indian Ocean monsoon and associated wind-driven transport of fertile and plankton-rich water in winter from the Gulf of Aden into the Red Sea. Subsequent evaporation and thermohaline circulation increase the salinity and decrease water temperatures toward the North. Compared with other ocean systems, however, relatively little is known about the zooplankton biodiversity of the Red Sea and how this relates to Red Sea latitudinal gradients. Among the most abundant zooplankton taxa are Chaetognatha, which play an important role as secondary consumers in most marine food webs. Since Chaetognatha are sensitive to changes in temperature and salinity, we surmised latitudinal changes in their biodiversity, community structure and diel variability along the coast of Saudi Arabia. Samples were collected at nine coral reefs spanning approximately 1500 km, from the Gulf of Aqaba in the northern Red Sea to the Farasan Archipelago in the southern Red Sea. Thirteen Chaetognatha species belonging to two families (Sagittidae and Krohnittidae) were identified. Latitudinal environmental changes and availability of prey (i.e. Copepoda, Crustacea) altered Chaetognatha density and distribution. The cosmopolitan epiplanktonic Flaccisagitta enflata (38.1%) dominated the Chaetognatha community, and its abundance gradually decreased from South to North. Notable were two mesopelagic species (Decipisagitta decipiens and Caecosagitta macrocephala) in the near-reef surface mixed layers at some sites. This was related to wind-induced upwelling of deep water into the coral reefs providing evidence of trophic oceanic subsidies. Most Sagittidae occurred in higher abundances at night, whereas Krohnittidae were more present during the day. Chaetognatha with developing (stage II) or mature ovaries (stage III) were more active at night, demonstrating stage-specific diel vertical migration as a potential predator avoidance strategy.
