    Description: Arctic landscapes are characterized by diverse water bodies, which are covered with ice for most of the year. Ice controls surface albedo, hydrological properties, gas exchange, and ecosystem services, but freezing processes differ between water bodies. We studied the influence of geomor-phology and meteorology on winter ice of water bodies in the Lena Delta, Siberia. Electrical conductivity (EC) and stable water isotopes of ice cores from four winters and six water bodies were measured at unprecedented resolution down to 2-cm increments, revealing differences in freezing systems. Open-system freezing shows near-constant isotopic and EC gradients in ice, whereas closed-system freezing shows decreasing isotopic composition with depth. Lena River ice displays three zones of isotopic composition within the ice, reflecting open-system freezing that records changing water sources over the winter. The isotope composition of ice covers in landscape units of different ages also reflects the individual water reservoir settings (i.e., Pleistocene vs. Holocene ground ice thaw). Ice growth models indicate that snow properties are a dominant determinant of ice growth over winter. Our findings provide novel insights into the winter hydro-chemistry of Arctic ice covers, including the influences of meteorology and water body geomor-phology on freezing rates and processes.

    Description: Neomphaloidean gastropods are endemic to chemosynthesis-based ecosystems ranging from hot vents to organic falls, and their diversity and evolutionary history remain poorly understood. In the southwestern Pacific, deep-sea hydrothermal vents on back-arc basins and volcanic arcs are found in three geographically secluded regions: a western region around Manus Basin, an eastern region around North Fiji and Lau Basins, and the intermediate Woodlark Basin where active venting was confirmed only recently, on the 2019 R/V L’Atalante CHUBACARC expedition. Although various lineages of neomphaloidean snails have been detected, typically restricted to one of the three regions, some of these have remained without names. Here, we use integrative taxonomy to describe three of these species: the neomphalid Symmetromphalus mithril sp. nov. from Woodlark Basin and the peltospirids Symmetriapelta becki sp. nov. from the eastern region and Symmetriapelta radiata sp. nov. from Woodlark Basin. A combination of shell sculpture and radular characters allow the morphological separation of these new species from their described congeners. A molecular phylogeny reconstructed from 570 bp of the mitochondrial cytochrome c oxidase subunit I gene confirmed the placement of the three new species in their respective genera and the superfamily Neomphaloidea. The finding of these new gastropods, particularly the ones from the Woodlark Basin, provides insights and implications on the historical role of Woodlark as a dispersing centre, in addition to highlighting the uniqueness of the Woodlark faunal community.

    Description: Sponges (Porifera) are one of the most ancient animals present on the planet. They are aquatic, filter-feeding sessile metazoans that rely on asexual and sexual reproduction. These animals have a long history on Earth and had plenty of time to develop different reproductive strategies. Here, we review different aspects of the physiology of reproduction in Porifera. This chapter is divided into six sections. In the first section, we present general features of sponge reproduction, such as factors that trigger the onset of their reproduction, as well as the periodicity of their reproductive cycles. The molecular basis of the hormonal control of gametogenesis is presented although sponges have no endocrine system. The second section deals with gametogenesis, 2including how sex and the germline are determined and maintained in this group, how oocytes and spermatozoa are formed and nourished, and how they behave once released. The third section reviews different topics about the reproductive mode. Here, we discuss the dichotomy in reproductive mode: oviparity vs. viviparity, the spatial distribution of the reproductive elements in the sponge tissue, the effect of symbiosis in reproduction (and vice-versa), and energetic trade-offs during reproduction. The fourth section describes fertilization, and we cover the factors controlling the spawning events and how the sperm are attracted and recognized by the egg. The diversity of developmental modes, the molecular control of sponge embryonic development, and the maternal-embryo relationship are discussed in the fifth section. Finally, in the sixth section, the types of asexual reproduction, factors influencing budding, gemmulation, hibernation, and gemmule development are described. Knowledge about the physiology of reproduction of sponges is still fragmentary and based on studies in very few species. Consequently, there are many generalizations that need further investigation. However, evidence-based on morphological, experimental, and molecular data demonstrates that their physiology is not very different from that of other metazoans

    Description: We report on about 20 yr of relative gravity measurements, acquired on Mt. Somma–Vesuvius volcano in order to investigate the hydrological and volcano-tectonic processes controlling the present-day activity of the volcano. The retrieved long-term field of time gravity change (2003–2022) shows a pattern essentially related to the subsidence, which have affected the central part of the volcano, as detected by the permanent GNSS network and InSAR data. After reducing the observations for the effect of vertical deformation, no significant residuals are found, indicating no significant mass accumulation or loss within the volcanic system. In the north-western sector of the study area, at the border of the volcano edifice, however, significant residual positive gravity changes are detected which are associated to ground-water rebound after years of intense exploitation of the aquifers. On the seasonal timescale, we find that stations within the caldera rim are affected by the seasonal hydrological effects, while the gravity stations at the base of the Vesuvius show a less clear correlation. Furthermore, within the caldera rim a multiyear gravity transient is detected with an increase phase lasting about 4 yr followed by a slower decrease phase. Analysis of rain data seem to exclude a hydrological origin, hence, we hypothesize a deeper source related to the geothermal activity, which can be present even if the volcano is in a quiescent state. We infer the depth and volume of the source by inverting the spatial pattern of the gravity field at the peak of the transient. A volume of fluids of 9.5 × 107 m3 with density of 1000 kg m−3 at 2.3 km depth is capable to fit reasonably well the observations. To explain the gravity transient, simple synthetic models are produced, that simulate the ascent of fluids from a deep reservoir up to the depth of 2.3 km and a successive diffusion within the carbonate aquifer hosting the geothermal system. The whole process appears to not significantly affect the seismicity rate and the deformation of the volcano. This study demonstrates the importance of a 4-D gravity monitoring of a volcano to understand its complex gravity signals that cover different spatial and temporal scales. Discriminating the different contributions that mix up in the observed gravity changes, in particular those due to hydrologic/anthropogenic activities form those due to the geothermal dynamics, is fundamental for a complete and reliable evaluation of the volcano state.

    Description: The extent of our duties to mitigate climate change is commonly conceptualized in terms of temperature goals like the 1.5°C and the 2°C target and corresponding emissions budgets. While I do acknowledge the political advantages of any framework that is relatively easy to understand, I argue that this particular framework does not capture the true extent of our mitigation duties. Instead I argue for a more differentiated approach that is based on the well-known distinction between subsistence and luxury emissions. At the heart of this approach lies the argument that we have no budget of substantial, net-positive luxury emissions left. In a world in which dangerous climate change has begun, we must expect all further substantial, net-positive luxury emissions to cause harm. Since they lack the kind of justification needed for them to be nevertheless permissible, I conclude that we must stop emitting them with immediate effect. I also briefly discuss the difficult case of subsistence emissions and offer some first thoughts on the morality of a third category of emissions, what I call ‘transition emissions’.

    Description: Misterbianco, located on the southern slope of Mt. Etna (eastern Sicily), was destroyed in the past by two catastrophic events that raised the old town to the ground. The first was the great eruption of 1669, whose lava front buried dozens of villages encountered along its path, entirely destroying the architectural heritage of Etna's southern flank. The second event was the disastrous 1693 Val di Noto earthquake, which caused major destruction throughout south-eastern Sicily, also damaging the few still standing buildings in the town. The GPR survey performed at this site, 350 years after the eruption, allowed a first attempt of planimetric reconstruction of the San Nicolò Church. Starting from the site history, we present the results of an integrated approach that involves history, volcanology and geophysics aimed at addressing future archaeological excavations for the protection of archaeological and monumental assets in a difficult setting as this volcanic environment.

    Description: With a focus on migrant narratives, or the storytelling about migration, this volume considers the ways in which migration is and has been shaped by individual and collective experiences of agency, belonging and community. Driven by an agenda of deep listening, each chapter presents a narrative directly derived from qualitative research, an outline of the methodological framing as well as narrative analysis. Through close attention to the narrative, its performative aspects and its ruptures and silences, authors identify patterns and material in the fabric of such telling and retelling of stories that open up new perspectives on the migrant experience. This book develops a methodology of ""dwelling with stories"" that allows for sustained and slow interrogation of the migrant experience and the accompanying decisions that shape narratives around mobility across borders. Its structure is innovative by emphasising the migrant voice and reflecting on the scholars’ positionality, while also offering new theoretical contributions that will advance the field of narrative analysis. The book will appeal to academics, students and practitioners in a wide range of subject areas within the humanities and social sciences, including anthropology, sociology, human geography, migration/refugee/diaspora studies and oral history.

    Description: Living with Energy Poverty: Perspectives from the Global North and South expands our collective understanding of energy poverty and deepens our recognition of the phenomenon by engaging with the lived experiences of energy-poor households across different contexts. Understanding the lived experience of energy poverty is an essential component in the design of any effort to alleviate what is fundamentally a deep-rooted, multi-faceted, wickedly complex problem. This requires a nuanced understanding of the causal factors and the research methods that can respond to the flexible spatial and temporal nature of the condition, as well as its wellbeing and justice implications. Drawing together the expertise and connectedness of authors from the Global South and North, this book presents novel approaches to understanding the often hidden forms of domestic energy deprivation. Case studies from 20 countries provide critical perspectives on this phenomenon while analysing the policy practices, government strategy, and sustainability implications of divergent manifestations. The book takes a multidimensional perspective, challenging the bias towards energy production and service provision, which often do not align with the aspirations and realities of energy households across global contexts, thus facilitating a useful dialogue on the nature of energy poverty. The book is a timely source for policymakers, practitioners, and scholars seeking fresh, diverse insights into the everyday reality of energy poverty and wanting to better understand the challenges a people-centred, just energy transition can present.

    Description: This chapter discusses monogamism as a type of systemic oppression enacted through ideas and practices that valorise monogamous people and relationships while systematically devaluing polyamorous and multi-partnered relationships. Instead of focusing on polyamorous/multi-partnered people, this chapter will apply the critical gaze of a sex and relationship therapist with polyamorous lived experience to examine and critique how psychotherapists behave toward polyamorous/multi-partnered people. Ansara explores how psychotherapists routinely engage in three common forms of monogamism: mononormative bias, couple-centric bias, and everyday monogamism. When examining these three forms of monogamism, Ansara explains how some ostensibly “neutral” and ubiquitous language, concepts, and clinical practices can enact monogamist oppression. This chapter then analyses how popular theoretical approaches to relationship counselling promote couple-centric bias and fail to address the key patterns, dynamics, and dilemmas in multi-partnered relationship systems. This includes an anti-racist, decolonial critique of Eurocentric approaches to Attachment Theory and the culture-bounded nature of mononormative biases. Finally, this chapter provides evidence-informed guidelines for anti-oppressive psychotherapeutic practice that can help polyamorous and multi-partnered people to strengthen attachment bonds, improve communications, and meet core emotional needs in their relational systems.
