Domestication and artificial selection for desirable traits have driven significant phenotypic changes and left detectable genomic footprints in farmed animals. Since the 1960s, intensive breeding has led to the rapid domestication of Atlantic salmon (Salmo salar), with multiple independent events that make it a valuable model for studying early domestication stages and the parallel evolution of populations of different origins subjected to simil [...]
Scenarios are vital for exploring potential futures and guiding policy towards desirable outcomes. However, current approaches to developing social-ecological scenarios often have limitations such as a primary focus on impacts of socioeconomic developments on nature’s contributions to people, and insufficient incorporation of diverse values and knowledge systems. The Nature Futures Framework (NFF), developed under the Intergovernmental Science-Po [...]
Since 2011, massive strandings of holopelagic Sargassum have occurred on the coasts of the Caribbean and of West Africa. Although open ocean Sargassum mats are oases of biodiversity, their stranding has a number of negative ecological, economic and health consequences. To limit these impacts, Sargassum needs to be collected as quickly as possible to avoid its decomposition, which requires accurate predictions of the date, location and abundance o [...]
The voluntary carbon market is presented as a solution to fund land and ecosystem restoration in developing economies. While the empirical literature has focused on assessing its ecological effectiveness, limited attention has been given to how this market interacts with other funding streams within national contexts. Delineating the types of projects that the voluntary carbon market can effectively fund is essential for designing a coherent and [...]
Oxidation of Fe2+ by anoxic water in the subsurface is a key geochemical process, contributing to the formation of natural dihydrogen (H2). The development and application of effective tools to accurately characterize the content and speciation of iron in samples is thus a major concern for H2 prospection. Traditionally, the study of iron has been conducted through either time-consuming analyses at the micrometer scale or faster analyses at the b [...]
Human activities have introduced significant amounts of anthropogenic chemicals into marine ecosystems, posing threats to aquatic biodiversity and human health. Although, traditional marine monitoring focus primarily on legacy pollutants, the presence and potential risks associated with complex emerging chemical mixtures should not be neglected. In the context of the present study organized via OSPAR Commission and supported by NORMAN network, 52 [...]
The Philippines, situated at the apex of the Coral Triangle, is fringed by both modern and fossil coral reefs that preserve valuable records of Quaternary relative sea-level changes and tectonic deformation. This study presents a new interpretation of the formation of the Late Pleistocene coral reef terraces at Cape Bolinao in western Luzon, offering insights into sea-level history, reef development, and tectonic uplift within the northern Coral [...]
Over the past decades, stable isotopes have been infrequently used to characterise host-parasite trophic relationships. This is because we have not yet identified consistent patterns in stable isotope values between parasites and their host tissues across species, which are crucial for understanding host-parasite dynamics. To address this, we initiated a worldwide collaboration to establish a unique database of stable isotope values of novel host [...]
L’objet de ce document est d’examiner les données acquises en amont de l'attribution des parcs par des bureaux d’étude mandatés par la Direction Générale de l’Energie et du Climat (DGEC), et qui seront ensuite fournies par la DGEC aux futurs lauréats des appels d’offre des parcs éoliens offshore 4 (Centre Manche 1) et 5 (Bretagne Sud) pour la constitution des états initiaux de l’environnement. La DGEC souhaite avoir un retour sur les capacités de [...]
Présentation des résultats du suivi des développements d’algues vertes dans les masses d’eau littorales de l’île d’Oléron dans le cadre du réseau de contrôle de surveillance DCE – Campagne 2022 Ce suivi s’inscrit dans le cadre du Réseau de Contrôle de Surveillance (RCS) de la Directive Cadre sur l’Eau (DCE). Il repose sur l’analyse des données recueillies entre 2010 et 2023, incluant notamment des survols aériens et des opérations de terrain. Le [...]

The collections of ghost shrimps from the Indo-West Pacific that contributed to recent molecular phylogeny and resulting reclassification of Callianassidae (Poore et al., 2019; Robles et al., 2020) provide opportunities to review 11 genera and describe one new genus, redescribe existing species and describe 21 new species. Aqaballianassa aqabaensis (Dworschak, 2003), A. brevirostris (Sakai, 2002), A. lewtonae (Ngoc-Ho, 1994) are rediagnosed and A [...]
Apristurus yangi, a new species of deepwater catshark, is described from Papua New Guinea based on two specimens collected during recent deepwater surveys. The new species belongs to the longicephalus-group which is characterised by its very long snout compared to members of the brunneus-group and spongiceps-groups. Apristurus yangi differs from its closest congeners in a combination of the following characters: 8 intestinal spiral valves; mouth [...]
We present the most comprehensive phylogeny of a globally distributed deep-sea group of gastropods published to date including over 80% of the recognized diversity of the family Scaphandridae. The definition and taxonomic composition of the Scaphandridae has been hampered by the lack of a sound phylogenetic framework and definition of synapomorphic traits. We used a combination of molecular phylogenetics (Bayesian Inference and Maximum Likelihood [...]
New molecular phylogenies of the chemosymbiotic bivalve family Lucinidae, using 18S rRNA, 28S rRNA and cytochrome b genes, include species from genera not previously analysed. Notable additions from Myrteinae are sequences from Rostrilucina, Solelucina and Taylorina species, species of Ustalucina, Gonimyrtea from Leucosphaerinae and additional species of Ctena, Codakia, Lucinoma and Divalucina from Codakiinae. New sequences of Lucininae include t [...]
Munidopsid squat lobsters are among the most abundant decapods at abyssal depths and the most diverse squat lobster group in the East Pacific region. During recent cruises along the East Pacific, many deep-sea squat lobsters were collected. Among these, we described five new munidopsid species supported both by morphological characters and molecular phylogenetics: Munidopsis girguisi sp. nov., M. nautilus sp. nov., M. testuda sp. nov., M. cortesi [...]
Additional spider crab (superfamily Majoidea) material from four major French-led expeditions to the Papua New Guinea region were examined in this study. One new genus and four new species from the families Inachidae and Oregoniidae are described. Dorhynchus profundus n. sp. is close to D. rostratus (Sakai, 1932) but can easily be separated by the shape of the ambulatory dactylus and the proportionately lower protogastric spines. Achaeus pholcus [...]
Metacrimenes fenestra, a new palaemonid genus and species is described on the basis of an ovigerous female and one juvenile specimen from Suruga Bay, central Japan. The specimens were associated with the stalked crinoid Metacrinus rotundus Carpenter, 1885, collected at a depth of 131-200 m. Photographs taken in situ indicate that the shrimp lives ectosymbiotically on its crinoid host. The greatly reduced bud-like exopod on the third maxilliped li [...]
The pantropical genus Palaemonella Dana, 1852 (Caridea: Palaemonidae) currently includes 27 species of free-living and symbiotic marine shrimps. The monophyly of Palaemonella with respect to several closely related genera, however, has been questioned by recent analyses. We tested the monophyly of Palaemonella based on multigene phylogenetic analysis and the genus was revealed to be a paraphyletic assemblage by inclusion of species of the genera [...]
