Given their irreplaceable role in ecosystems and their high extinction risk, we used a 24-year time series (1997{\textendash}2020) of scientific bottom trawl surveys to examine the effects of climate change on the spatial distribution of nine elasmobranch species within Northeast Atlantic waters. Using a hierarchical modeling of species communities, belonging to the joint species distribution models, we found that suitable habitats for four species increased on average by a factor of 1.6 and, for six species, shifted north-eastwards and/or to deeper waters over the past two decades. By integrating species traits, we showed changes in habitat suitability led to changes in the elasmobranchs trait composition. Moreover, communities shifted to deeper waters and their mean trophic level decreased. We also note an increase in the mean community size at maturity concurrent with a decrease in fecundity. Because skates and sharks are functionally unique and dangerously vulnerable to both climate change and fishing, we advocate for urgent considerations of species traits in management measures. Their use would make it better to identify species whose loss could have irreversible impacts in face of the myriad of anthropogenic threats.}, issn = {1354-1013}, doi = {10.1111/gcb.v30.110.1111/gcb.17157}, url = {https://onlinelibrary.wiley.com/toc/13652486/30/1https://onlinelibrary.wiley.com/doi/10.1111/gcb.17157https://onlinelibrary.wiley.com/doi/pdf/10.1111/gcb.17157}, author = {Coulon, No{\'e}mie and Elliott, Sophie and Teichert, Nils and Auber, Arnaud and McLean, Matthew and Barreau, Thomas and Feunteun, Eric and Carpentier, Alexandre} } @article {9222, title = {Nanopore long-reads reveal fine structure of prokaryotic communities in mangrove sediments, like Illumina short-reads but with twice more taxa}, journal = {bioRxiv}, volume = {10.1101/2023.06.06.541006}, year = {2023}, doi = {10.1101/2023.06.06.541006}, author = {Alice Lemoinne and Guillaume Dirberg and Myriam Georges and Tony Robinet} } @article {9460, title = {The Neglected Role of Intraspecific Variation in Plastic Pollution Research}, journal = {Anthropocene Science}, volume = {2}, year = {2023}, pages = {141-147}, doi = {https://doi.org/10.1007/s44177-023-00060-6}, author = {Nicastro, Katy R. and Seuront, Laurent and Lorenzo Cozzolino and Zardi, Gerardo I.} } @article {9117, title = {New insights into the diversity of cryptobenthic Cirripectes blennies in the Mascarene Archipelago sampled using Autonomous Reef Monitoring Structures (ARMS)}, journal = {Ecology and Evolution}, volume = {13}, year = {2023}, month = {Jan-03-2023}, issn = {2045-7758}, doi = {10.1002/ece3.v13.310.1002/ece3.9850}, url = {https://onlinelibrary.wiley.com/toc/20457758/13/3}, author = {Marion Cou{\"e}del and Dettai, Agn{\`e}s and Mireille M.M.

Partial Cytochrome c oxydase I (COI) was amplified and sequenced. For each specimen, the 582 bp long sequences obtained from the internal tissue, the fin clip and the eggs were identical.

Investigating the structure and the function of planktonic food webs in two SW Mediterranean waters (inshore and marine sites) at four seasons, using inverse (LIM-MCMC) and ecological network (ENA) analyses, we identified a new type of food web, called the {\textquotedblleft}bacterial multivorous food web{\textquotedblright}. This food web adds to the conventional trophic continuum as previously reported. The {\textquotedblleft}bacterial multivorous food web{\textquotedblright} present in winter showed the lowest primary production among seasons, but highest bacterial production. Several food web ratios characterized this new typology e.g. picophytoplankton net primary production to total primary production varied from 0.20 to 0.28; bacterial to primary production ratio is higher than values reported in global scale (≅1); bacterial net production to the potential protozoan prey net production was high (\>0.2). In this special food web, carbon was mostly recycled, with a moderate fraction channeled to deep waters, which lead to a higher retention of carbon inside the ecosystem. This winter PFW also seemed to be the most organized, specialized, stable and mature, as related to common interpretations of ENA. The spring was characterized by herbivorous food web, with highest activity coinciding with low stability. Although less usual, the herbivorous pathway was also observed during summer, in inshore waters. The autumn food webs, which functioned as multivorous or microbial food webs, appeared to be stable and mature. Finally, our study demonstrates the usefulness of food web models derived ratios combined with ecological network analysis indices to conduct evaluation of the structure and functioning of ecosystems and potentially to support management decisions in marine environment. {\textcopyright} 2019}, keywords = {Bacteria (microorganisms), bacterium, Carbon, Chemical contamination, coastal water, Coastal waters, ecological modeling, Ecology, ecosystem function, Ecosystems, Electric network analysis, Food microbiology, food web, Food web model, Food webs, inverse analysis, Inverse problems, Markov chain, Markov processes, Mediterranean sea, Monte Carlo analysis, Monte Carlo methods, net primary production, network analysis, Phytoplankton, picoplankton, Plankton, Protozoa, protozoan, Seasonal variation, trophic status, Trophic structure}, issn = {1470160X}, doi = {10.1016/j.ecolind.2019.04.077}, url = {https://www.sciencedirect.com/science/article/abs/pii/S1470160X19303243}, author = {Meddeb, M. and Nathalie Niquil and Grami, B. and Mejri, K. and Haraldsson, M. and Chaalali, A. and Pringault, O. and Hlaili, A.S.} } @article {6634, title = {The nanos1 gene was duplicated in early Vertebrates and the two paralogs show different gonadal expression profiles in a shark}, journal = {Scientific Reports}, volume = {8}, year = {2018}, month = {Jan-12-2018}, doi = {10.1038/s41598-018-24643-1}, url = {http://www.nature.com/articles/s41598-018-24643-1}, author = {Gribouval, Laura and Pascal Sourdaine and Lareyre, Jean-Jacques and Bellaiche, Johanna and Le Gac, Florence and Mazan, Sylvie and Guiardiere, C{\'e}cile and Auvray, Pierr{\"\i}ck and Aude Gautier} } @article {5924, title = {A new species of Schismatogobius (Teleostei: Gobiidae) from Halmahera (Indonesia)}, journal = {Cybium}, volume = {42}, year = {2018}, pages = {195-200}, abstract = {

Mass blooms of purple sulfur bacteria growing seasonally on green stranded macroalgae have a major impact on the microbial composition and functionality of intertidal mats. To explore the active anoxygenic phototrophic community in purple bacterial mats from the Roscoff Aber Bay (Brittany, France), we conducted a combined approach including molecular and high-resolution secondary ion mass spectrometry (NanoSIMS) analyses. To investigate the dynamics of carbon and nitrogen assimilation activities, NanoSIMS was coupled with a stable isotope probing (SIP) experiment and a compound specific isotope analysis (CSIA) of fatty acid methyl ester (FAME). Sediment samples were incubated with 13C- and/or 15N-labelled acetate, pyruvate, bicarbonate and ammonium. NanoSIMS analysis of 13C - and 15N -incubated samples showed elevated incorporations of 13C - and 15N in the light and of 13C -acetate in the dark into dense populations of spherical cells that unambiguously dominated the mats. These results confirmed CSIA data that ranked vaccenic acid, an unambiguous marker of purple sulfur bacteria, as the most strongly enriched in the light after 13C -acetate amendment and indicated that acetate uptake, the most active in the mat, was not light-dependent. Analysis of DNA- and cDNA-derived pufM gene sequences revealed that Thiohalocapsa-related clones dominated both libraries and were the most photosynthetically active members of the mat samples. This study provides novel insights into the contribution of purple sulfur bacteria to the carbon cycle during their seasonal developments at the sediment surface in the intertidal zone.

Marine habitat function has been typically investigated in terms of biogeochemical regulation but rarely in terms of population renewal, which is mainly controlled by recruitment dynamics. The recruitment phase is crucial for
organisms with a bentho-pelagic life cycle, such as bivalves, and it regulates the population renewal success. This study provides new insight on the role of temperate benthic habitats on bivalve recruitment, as a function of
nursery areas. Six dominant benthic habitats of the Chausey archipelago (Normandy, France) were studied. In each habitat, bivalve recruit assemblages were described at the end of two reproductive seasons. Furthermore, Ostrea edulis
juveniles were immerged on each habitat during two months to compare growth performances and feeding status, estimated by fatty acid composition. Recruit assemblages differ from each habitat according to sediment grain-size composition and bathymetrical levels. Subtidal habitats, and especially Crepidula fornicata banks and Glycymeris glycymeris coarse sands, supported the highest species abundance and richness of recruits. All O. edulis juveniles fed on the same trophic resources but digestive glands of juveniles from C. fornicata banks were more concentrated in total fatty acids than those from subtidal G. glycymeris coarse sands and maerl banks. Our results depict the key role of subtidal and structured habitats, composed of ecosystem engineers, in enhancing bivalve recruitment and extending the bivalve population renewal. This study suggests that the crucial role of
these habitats as bivalve nurseries must be integrated in management perspectives

Cephalopods possess the most complex centralized nervous system among molluscs and the molecular determinants of its development have only begun to be explored. To better understand how evolved their brain and body axes, we studied Sepia officinalis embryos and investigated the expression patterns of neural regionalization genes involved in the mediolateral patterning of the neuroectoderm in model species. SoxB1 expression reveals that the embryonic neuroectoderm is made of several distinct territories that constitute a large part of the animal pole disc. Concentric nkx2.1, pax6/gsx, and pax3/7/msx/pax2/5/8 positive domains subdivide this neuroectoderm. Looking from dorsal to ventral sides, the sequence of these expressions is reminiscent of the mediolateral subdivision in model species, which provides good evidence for "mediolateral patterning" conservation in cephalopods. A specific feature of cephalopod development, however, includes an unconventional orientation to this mediolateral sequence: median markers (like nkx2.1) are unexpectedly expressed at the periphery of the cuttlefish embryo and lateral markers (like Pax3/7) are expressed centrally. As the egg is rich with yolk, the lips of the blastopore (that classically organizes the neural midline) remain unclosed at the lateral side of the animal pole until late stages of organogenesis, therefore reversing the whole embryo topology. These findings confirm - by means of molecular tools - the location of both ventral and dorsal poles in cephalopod embryos.

Silvering is a prepubertal metamorphosis preparing the eel to the oceanic reproductive migration. A moderate gonad development occurs during this metamorphosis from the sedentary yellow stage to the migratory silver stage. The aim of this study was to elucidate the molecular aspects of various endocrine parameters of BPG axis at different ovarian developmental stages in wild yellow and silver female Japanese eels. The GSI of the sampled female eels ranged between 0.18 and 2.3\%, corresponding to yellow, pre-silver and silver stages. Gonad histology showed changes from previtellogenic oocytes in yellow eels to early vitellogenic oocytes in silver eels. Both serum E2 and T concentrations significantly increased with ovarian development indicating a significant activation of steroidogenesis during silvering. In agreement with previous studies, significant increases in pituitary gonadotropin beta subunits FSH-β and LH-β transcripts were also measured by qPCR, supporting that the activation of pituitary gonadotropin expression is likely responsible for the significant ovarian development observed during silvering. We investigated for the first time the possible brain neuroendocrine mechanisms involved in the activation of the pituitary gonadotropic function during silvering. By analyzing the expression of genes representative of the stimulatory GnRH control and the inhibitory dopaminergic control. The transcript levels of mGnRH and the three GnRH receptors did not change in the brain and pituitary between yellow and silver stages, suggesting that gene expression of the GnRH system is not significantly activated during silvering. The brain transcript levels of tyrosine hydroxylase, limiting enzyme of DA synthesis did not change during silvering, indicating that the DA synthesis activity was maintained. In contrast, a significant decrease in DA-D2B receptor expression in the forebrain and pituitary was observed, with no changes in DA-D2A receptor. The decrease in the pituitary expression of DA-D2BR during silvering would allow a reduced inhibitory effect of DA. We may raise the hypothesis that this regulation of D2BR gene expression is one of the neuroendocrine mechanisms involved in the slight activation of the pituitary gonadotropin and gonadal activity that occur at silvering.

Cephalopods are new evolutionary and ecological models.
By their phylogenetic position (Lophotrochozoa, Mollusca),
they provide a missing master piece in the whole puzzle of
neurodevelopment studies. Their derived and specific nervous
system but also their convergence with vertebrates offer
abundant materials to question the evolution and development
of the nervous system of Metazoa (evo-devo studies). In
addition, their various adaptions to different modes of life
open new fields of investigation of developmental plasticity
according to ecological context (eco-evo-devo approach). In
this paper, we review the recent works on cephalopod nervous
developmental investigations. We show how cephalopods, and
especially Sepia officinalis, an animal of economical interest,
can be used as suitable models to extend our knowledge on
cephalopod ecology and on nervous system evolution among
molluscs.

BACKGROUND: Oysters impart significant socio-ecological benefits from primary production of food supply, to estuarine ecosystems via reduction of water column nutrients, plankton and seston biomass. Little though is known at the molecular level of what genes are responsible for how oysters reproduce, filter nutrients, survive stressful physiological events and form reef communities. Neuropeptides represent a diverse class of chemical messengers, instrumental in orchestrating these complex physiological events in other species.

RESULTS: By a combination of in silico data mining and peptide analysis of ganglia, 74 putative neuropeptide genes were identified from genome and transcriptome databases of the Akoya pearl oyster, Pinctata fucata and the Pacific oyster, Crassostrea gigas, encoding precursors for over 300 predicted bioactive peptide products, including three newly identified neuropeptide precursors PFGx8amide, RxIamide and Wx3Yamide. Our findings also include a gene for the gonadotropin-releasing hormone (GnRH) and two egg-laying hormones (ELH) which were identified from both oysters. Multiple sequence alignments and phylogenetic analysis supports similar global organization of these mature peptides. Computer-based peptide modeling of the molecular tertiary structures of ELH highlights the structural homologies within ELH family, which may facilitate ELH activity leading to the release of gametes.

CONCLUSION: Our analysis demonstrates that oysters possess conserved molluscan neuropeptide domains and overall precursor organization whilst highlighting many previously unrecognized bivalve idiosyncrasies. This genomic analysis provides a solid foundation from which further studies aimed at the functional characterization of these molluscan neuropeptides can be conducted to further stimulate advances in understanding the ecology and cultivation of oysters.

Since 1861, freshwater fishes have been studied at different periods in New Caledonia. The first list was published in 1915, but the
major inventories were done between 1998 and 2003. These inventories allowed the discovery of many new species and the publication,
in 2003, of the Atlas of Freshwater fish and crustaceans of New Caledonia, which listed 64 freshwater fish species. Between 2004
and 2010, additional specific surveys were conducted by the MNHN and 9 species were added. Among them, 3 were new for science.
Gobiidae family represents 30\% of the freshwater fishes of New Caledonia. This high percentage is explained by their particular life
cycle adapted to insular systems.

They spawn in freshwater, their planktotrophic larvae drift downstream to the sea where they develop, before returning to the rivers to grow and reproduce. Hence, they are called amphidromous. Their phylogeny has been explored using a total of 3545 sites from 5 molecular markers (mitochondrial DNA: 16S rDNA, cytochrome oxidase I, cytochrome b; nuclear DNA: rhodopsin gene and a nuclear marker specially developed for this study, the interferon regulatory factor 2 binding protein 1-IRF2PB1). Sequences were obtained for 59 Sicydiinae specimens of 9 known genera. The Bayesian and maximum likelihood analyses support the monophyly of the subfamily as well as the monophylyof all genera except Sicydium, which is paraphyletic. Five major clades were identified within this subfamily. One clade contained the genus Stiphodon. Another clade contained Sicyopterus, Sicydium and Parasicydium with Sicyopterus as sister genus of Sicydium. The non-monophyly of Sicydium subclade, because it includes the monotypic genus Parasicydium, challenged the validity of Parasicydium genus. Ancestral area reconstruction showed that the subfamily emerged in the Central West Pacific region implying that previous hypotheses proposing a dispersal route for Sicydiinae into the Atlantic Ocean are unsupported by the present analysis. Our results suggest that the hypotheses for the dispersal route of the genus Sicydium should be reconsidered.

Sicyopus rubicundus n. sp., a sicydiine goby, is described from specimens collected in streams of\ Java and Bali (Indonesia). It differs from other species of this amphidromous genus by a combination of characters\ including a first dorsal fin with five spines in both sexes, a second dorsal fin with one spine and nine segmented\ rays, an anal fin with one spine and nine segmented rays, and a distinctive body colour in male.
