Such an effect, named carry-over, can occur in fish nursery grounds when juvenile performances after settlement are influenced by their larval traits in combination with conditions experienced in nurseries. To date, the impacts of environmental and human stressors on post-settlement traits have been assessed, but independently from larval traits, so that the contributions of environmental versus carry-over constraints remain unquantified. Here, we used a reconstructive approach based on otolith microstructure to investigate how carry-over and environment affect life-history traits of the European seabass,\ Dicentrarchus labrax. In the northeast Atlantic Ocean, seabass juveniles were collected in six French estuarine nursery areas with contrasted environmental conditions (water temperature, salinity, food availability, and anthropogenic impacts), and five of their life-history traits across ontogenetic stages were measured (pelagic growth, larval duration, size at settlement, post-settlement growth and body condition). Piecewise structural equation model emphasized the strong co-variation of larval traits in response to food availability and temperature in the pelagic environment, stressing that fast growing larvae are characterized by shorter pelagic larval duration, but larger size at recruitment. However, the magnitude of carry-over effects greatly varied between traits, revealing that larval trait impacts on post-settlement traits remained minor as compared to the nursery environment. In estuarine nurseries, our findings suggest that resource allocation results from a trade-off between somatic growth and energy storage. Fish juveniles exposed to anthropogenic stress or risk of food limitation tended to predominantly invest in storage, whereas individuals in favourable conditions allocated their resources in somatic growth. These findings highlight the importance of heterogeneity in pelagic and nursery environments in understanding trait variations and population dynamic of estuarine dependent fish.}, issn = {00489697}, doi = {10.1016/j.scitotenv.2022.159487}, url = {https://linkinghub.elsevier.com/retrieve/pii/S004896972206586X}, author = {Teichert, Nils and Liz{\'e}, Anne and Cabral, Henrique and Acou, Anthony and Trancart, Thomas and Virag, Laure-Sarah and Feunteun, Eric and Alexandre Carpentier} } @article {9214, title = {Diet quality determines blue mussel physiological status: A long-term experimental multi-biomarker approach}, journal = {Journal of Experimental Marine Biology and Ecology}, volume = {563}, year = {2023}, month = {Jan-06-2023}, pages = {151894}, issn = {00220981}, doi = {10.1016/j.jembe.2023.151894}, url = {https://linkinghub.elsevier.com/retrieve/pii/S0022098123000266}, author = {Li{\'e}nart, Camilla and Tedengren, Michael and Garbaras, Andrius and Lim, Hwanmi and Chynel, Mathias and Robinson, Christophe and Tarik Meziane and Karlson, Agnes M.L.} } @article {9302, title = {Discovery of a Digenean (Cryptogonimidae) Living in a Cleft-Lipped Goby, Sicyopterus cynocephalus (Teleostei: Gobiidae) from Ranongga Island, Solomon Islands: Analysis of Multiple Ribosomal DNA Regions}, journal = {Pathogens}, volume = {12}, year = {2023}, month = {Jan-07-2023}, pages = {923}, doi = {10.3390/pathogens12070923}, url = {https://www.mdpi.com/2076-0817/12/7/923}, author = {Mathews, Patrick D. and Nicolas Rabet and L.

Studies in marine,4 freshwater,5 and terrestrial6 ecosystems have documented increasing CTI under global warming. However, most studies have only linked increasing CTI to increases in warm-affinity species. Here, using long-term monitoring of marine fishes across the Northern Hemisphere, we decomposed CTI changes into four underlying processes{\textemdash}tropicalization (increasing warm-affinity), deborealization (decreasing cold-affinity), borealization (increasing cold-affinity), and detropicalization (decreasing warm-affinity){\textemdash}for which we examined spatial variability and drivers. CTI closely tracked changes in sea surface temperature, increasing in 72\% of locations. However, 31\% of these increases were primarily due to decreases in cold-affinity species, i.e., deborealization. Thus, increases in warm-affinity species were prevalent, but not ubiquitous. Tropicalization was stronger in areas that were initially warmer, experienced greater warming, or were deeper, while deborealization was stronger in areas that were closer to human population centers or that had higher community thermal diversity. When CTI (and temperature) increased, species that decreased were more likely to be living closer to their upper thermal limits or to be commercially fished. Additionally, warm-affinity species that increased had smaller body sizes than those that decreased. Our results show that CTI changes arise from a variety of underlying community responses that are linked to environmental conditions, human impacts, community structure, and species characteristics.}, keywords = {bottom trawl, community temperature index, Fisheries, marine ecology, thermal affinity}, issn = {0960-9822}, doi = {https://doi.org/10.1016/j.cub.2021.08.034}, url = {https://www.sciencedirect.com/science/article/pii/S0960982221011386}, author = {Matthew McLean and David Mouillot and Aurore A.

Colonial central place foragers can reduce time to locate ephemeral food patches and/or increase foraging rate by following their informed peers, parasitizing direction of returning successful foragers, or being intentionally informed on distant food locations at the colony (e.g. the waggle dance of the honey bee). Ceremonial behaviours may also deliver social foraging information between mates, which can spread inadvertently to neighbours. Here we tested for information display in Cape gannets, Morus capensis, a socially monogamous species, during the elaborate dance ceremony performed each time a partner returns to the nest during the breeding season. We tracked fine-scale foraging behaviour of gannets using bird-borne GPS recorders, and videorecorded their subsequent dance ceremony, which involved up to 14 different displays. As we hypothesized, dance characteristics were associated with foraging trip features. Notably, overall dance duration was negatively linked to foraging trip duration, which was highly positively correlated with foraging range, foraging path length and time spent foraging during the trip. Overall dance duration was also negatively linked with distance to the main foraging grounds. Additionally, the duration of preening behaviour was related to the bearing of the main feeding spot. The latter relationship was supported by a Bayesian model averaging analysis, allowing inferences robust to multiple comparisons. Overall, ceremonial behaviour may provide social foraging information on feeding locations, while evidence for further information transfer to the mate or neighbours was not tested here. Frequent updating on prey spatial distribution, inadvertently communicated or not, should be particularly valuable for predators tracking ephemeral prey patches, providing an additional advantage to colonial living.

Most molluscs possess shells, constructed from a vast array of microstructures and architectures. The fully formed shell is composed of calcite or aragonite. These CaCO crystals form complex biocomposites with proteins, which although typically less than 5\% of total shell mass, play significant roles in determining shell microstructure. Despite much research effort, large knowledge gaps remain in how molluscs construct and maintain their shells, and how they produce such a great diversity of forms. Here we synthesize results on how shell shape, microstructure, composition and organic content vary among, and within, species in response to numerous biotic and abiotic factors. At the local level, temperature, food supply and predation cues significantly affect shell morphology, whilst salinity has a much stronger influence across latitudes. Moreover, we emphasize how advances in genomic technologies [e.g. restriction site-associated DNA sequencing (RAD-Seq) and epigenetics] allow detailed examinations of whether morphological changes result from phenotypic plasticity or genetic adaptation, or a combination of these. RAD-Seq has already identified single nucleotide polymorphisms associated with temperature and aquaculture practices, whilst epigenetic processes have been shown significantly to modify shell construction to local conditions in, for example, Antarctica and New Zealand. We also synthesize results on the costs of shell construction and explore how these affect energetic trade-offs in animal metabolism. The cellular costs are still debated, with CaCO precipitation estimates ranging from 1-2 J/mg to 17-55 J/mg depending on experimental and environmental conditions. However, organic components are more expensive (~29 J/mg) and recent data indicate transmembrane calcium ion transporters can involve considerable costs. This review emphasizes the role that molecular analyses have played in demonstrating multiple evolutionary origins of biomineralization genes. Although these are characterized by lineage-specific proteins and unique combinations of co-opted genes, a small set of protein domains have been identified as a conserved biomineralization tool box. We further highlight the use of sequence data sets in providing candidate genes for in situ localization and protein function studies. The former has elucidated gene expression modularity in mantle tissue, improving understanding of the diversity of shell morphology synthesis. RNA interference (RNAi) and clustered regularly interspersed short palindromic repeats - CRISPR-associated protein 9 (CRISPR-Cas9) experiments have provided proof of concept for use in the functional investigation of mollusc gene sequences, showing for example that Pif (aragonite-binding) protein plays a significant role in structured nacre crystal growth and that the Lsdia1 gene sets shell chirality in Lymnaea stagnalis. Much research has focused on the impacts of ocean acidification on molluscs. Initial studies were predominantly pessimistic for future molluscan biodiversity. However, more sophisticated experiments incorporating selective breeding and multiple generations are identifying subtle effects and that variability within mollusc genomes has potential for adaption to future conditions. Furthermore, we highlight recent historical studies based on museum collections that demonstrate a greater resilience of molluscs to climate change compared with experimental data. The future of mollusc research lies not solely with ecological investigations into biodiversity, and this review synthesizes knowledge across disciplines to understand biomineralization. It spans research ranging from evolution and development, through predictions of biodiversity prospects and future-proofing of aquaculture to identifying new biomimetic opportunities and societal benefits from recycling shell products.

Forecasting the phenology of fish migration is thus critically important to implement management actions aimed at protecting fish during their migration.
In this study, an 11-year monitoring survey of Atlantic salmon smolts (Salmo salar\ ) from the Ourthe River, Belgium, was analysed within a European Special Area of Conservation to improve the understanding of environment-induced spring migration. A logistic model was fitted to forecast smolt migration and to calculate phenological indicators for management, i.e. the onset, end, and duration of migration, while accounting for the influence of photoperiod, water temperature, and hydrological conditions.
The results indicated that the photo-thermal units accumulated by smolts above a 7{\textdegree}C temperature threshold was a relevant proxy to reflect the synergistic effect between temperature and photoperiod on smolt migration. After integrating the effect of river flow pulses, the model accurately explained the inter-annual changes in migration timing (R2\ = 0.95). The model predictions provide decisive management information to identify sensitive periods during which mitigation measures (e.g. hydropower turbine shutdown, river discharge management) should be conducted to promote smolt survival.
The model was used to predict phenological characteristics under future scenarios of climate change. The results suggest a joint effect of hydrological alterations and water warming. Temperature increases of 1{\textendash}4{\textdegree}C were associated with earlier initiation of migration, 6{\textendash}51 days earlier, and spring flood events greatly influenced the duration of the migration period. Accordingly, the combined effects of human-induced modifications of the hydrological regimes and increasing temperatures could result in a mismatch between the smolt and favourable survival conditions in the marine environment.}, issn = {1052-7613}, doi = {10.1002/aqc.3382}, url = {https://onlinelibrary.wiley.com/doi/abs/10.1002/aqc.3382}, author = {Teichert, Nils and Benitez, Jean-Philippe and Dierckx, Arnaud and T{\'e}tard, St{\'e}phane and Oliveira, Eric and Thomas Trancart and Eric Feunteun and Ovidio, Micha{\"e}l} } @article {7534, title = {Dietary taurine improves vision in different age gilthead sea bream (Sparus aurata) larvae potentially contributing to increased prey hunting success and growth}, journal = {Aquaculture}, year = {2020}, month = {Jan-11-2020}, pages = {736129}, issn = {00448486}, doi = {10.1016/j.aquaculture.2020.736129}, url = {https://linkinghub.elsevier.com/retrieve/pii/S0044848620338357}, author = {Gaon, A. and Nixon, O. and Tandler, A. and Falcon, J. and Besseau, L. and Escande, M. and El Sadin, S. and Allon, G. and Koven, W.} } @article {8080, title = {Differential Regulation of the Expression of the Two Thyrotropin Beta Subunit Paralogs by Salmon Pituitary Cells In Vitro}, journal = {Frontiers in Endocrinology}, volume = {11}, year = {2020}, month = {Mar-11-2022}, doi = {10.3389/fendo.2020.603538}, url = {https://www.frontiersin.org/articles/10.3389/fendo.2020.603538/full}, author = {Fleming, Mitchell Stewart and Maugars, Gersende and Martin, Patrick and Sylvie Dufour and Rousseau, Karine} } @article {7046, title = {Disentangling the taxonomy of the subfamily Rasborinae (Cypriniformes, Danionidae) in Sundaland using DNA barcodes}, journal = {Scientific Reports}, volume = {10}, year = {2020}, month = {Jan-12-2020}, abstract = {iodiversity hotspots have provided useful geographic proxies for conservation efforts. Delineated from a few groups of animals and plants, biodiversity hotspots do not reflect the conservation status of freshwater fishes. With hundreds of new species described on a yearly basis, fishes constitute the most poorly known group of vertebrates. This situation urges for an acceleration of the fish species inventory through fast and reliable molecular tools such as DNA barcoding. The present study focuses on the freshwater fishes diversity in the Sundaland biodiversity hotspot in Southeast Asia. Recent studies evidenced large taxonomic gaps as well as unexpectedly high levels of cryptic diversity, particularly so in the islands of Java and Bali. The Cypriniformes genera Rasbora and Nemacheilus account for most of the endemic species in Java and Bali, however their taxonomy is plagued by confusion about species identity and distribution. This study examines the taxonomic status of the Rasbora and Nemacheilus species in Java, Bali and Lombok islands through DNA barcodes, with the objective to resolve taxonomic confusion and identify trends in genetic diversity that can be further used for conservation matters. Several species delimitation methods based on DNA sequences were used and confirmed the status of most species, however several cases of taxonomic confusion and two new taxa are detected. Mitochondrial sequences argue that most species range distributions currently reported in the literature are inflated due to erroneous population assignments to the species level, and further highlight the sensitive conservation status of most Rasbora and Nemacheilus species on the islands of Java, Bali and Lombok.}, keywords = {Conservation genetics, Cryptic diversity, Population fragmentation, Southeast Asia, taxonomy}, doi = {10.1038/s41598-020-59544-9}, url = {http://www.nature.com/articles/s41598-020-59544-9}, author = {Sholihah, Arni and Delrieu-Trottin, Erwan and Sukmono, Tedjo and Dahruddin, Hadi and Risdawati, Renny and Elvyra, Roza and Wibowo, Arif and Kustiati, Kustiati and Busson, Frederic and Sauri, Sopian and Nurhaman, Ujang and Dounias, Edmond and Zein, Muhamad Syamsul Arifin and Fitriana, Yuli and Utama, Ilham Vemendra and Muchlisin, Zainal Abidin and Agn{\`e}se, Jean-Fran{\c c}ois and Hanner, Robert and Wowor, Daisy and Steinke, Dirk and Philippe Keith and R{\"u}ber, Lukas and Hubert, Nicolas} } @article {8460, title = {Diversit{\'e} des assemblages d{\textquoteright}araign{\'e}es dans les {\'e}cosyst{\`e}mes savanicoles des Plateaux Bat{\'e}k{\'e}, Haut-Ogoou{\'e}, Gabon}, journal = {Afrique Science}, volume = {16}, year = {2020}, pages = {106-117}, author = {Alban-Michel NGU{\'E}MA NGU{\'E}MA and Assane NDIAYE and Lynda Chancelia NKOGHE NKOGHE and Jacques Fran{\c c}ois MAVOUNGOU1 and Fr{\'e}d{\'e}ric Ysnel} } @article {8987, title = {Diversity of Light Sensing Molecules and Their Expression During the Embryogenesis of the Cuttlefish (Sepia officinalis)}, journal = {Frontiers in Physiology}, volume = {11}, year = {2020}, pages = {521989}, keywords = {arrestin, cryptochrome, Development, Eye, opsin, Sepia officinalis}, doi = {10.3389/fphys.2020.521989}, url = {https://hal.sorbonne-universite.fr/hal-02989850}, author = {Bonad{\`e}, Morgane and Ogura, Atsushi and Corre, Erwan and Bassaglia, Yann and Laure Bonnaud-Ponticelli} } @article {7376, title = {Does parasitism influence sediment stability?

Extreme events such as heat waves have increased in frequency and duration over the last decades. Under future climate scenarios, these discrete climatic events are expected to become even more recurrent and severe. Heat waves are particularly important on rocky intertidal shores, one of the most thermally variable and stressful habitats on the planet. Intertidal mussels, such as the blue mussel Mytilus edulis, are ecosystem engineers of global ecological and economic importance, that occasionally suffer mass mortalities. This study investigates the potential causes and consequences of a mass mortality event of M. edulis that occurred along the French coast of the eastern English Channel in summer 2018. We used an integrative, climatological and ecophysiological methodology based on three complementary approaches. We first showed that the observed mass mortality (representing 49 to 59\% of the annual commercial value of local recreational and professional fisheries combined) occurred under relatively moderate heat wave conditions. This result indicates that M. edulis body temperature is controlled by non-climatic heat sources instead of climatic heat sources, as previously reported for intertidal gastropods. Using biomimetic loggers (i.e. {\textquoteright}robomussels{\textquoteright}), we identified four periods of 5 to 6 consecutive days when M. edulis body temperatures consistently reached more than 30 {\textdegree}C, and occasionally more than 35 {\textdegree}C and even more than 40 {\textdegree}C. We subsequently reproduced these body temperature patterns in the laboratory to infer M. edulis thermal tolerance under conditions of repeated heat stress. We found that thermal tolerance consistently decreased with the number of successive daily exposures. These results are discussed in the context of an era of global change where heat events are expected to increase in intensity and frequency, especially in the eastern English Channel where the low frequency of commercially exploitable mussels already questions both their ecological and commercial sustainability.

In P. australis, the cellular DA content was rather a function of cell size. More particularly, cells at the gametangia stage of their life cycle contained up to six times more DA than smaller or larger cells incapable of sexual reproduction. These findings reveal a link between P. australis life cycle and cell toxicity.

Sicydiinae gobies have an amphidromous life cycle. Adults grow, feed, and reproduce in rivers, while larvae have a marine dispersal phase. Larvae recruit back to rivers and settle in upstream habitats. Within the Sicydiinae subfamily, the\ Sicyopterus genus, one of the most diverse (24 species), is distributed in the tropical islands of the Indo-Pacific. One of the characters used to determine Sicyopterus species is the upper lip morphology, which can be either smooth, crenulated, or with papillae, and with (2 or 3) or without clefts. The mouth is used as a secondary locomotor organ along with the pelvic sucker. It is thus strongly related to the climbing ability of species and is of major importance for the upstream migration and the colonization of insular freshwater systems. The mouth also has an important role in the feeding mechanism of these herbivorous species. In this paper, we have established a molecular phylogeny of the genus based on the 13 mitochondrial protein-coding genes to discuss the relationship between 18 Sicyopterus species. There is a well-supported dichotomy in the molecular phylogeny of the Sicyopterus genus and this separation into two clades is also morphologically visible, with the distinction of species with three clefts and species with 0 or 2 clefts on the upper lip. The mouth morphology can thus be separated with regard to the molecular phylogeny obtained. The evolution of the mouth morphology is discussed in terms of the adaptation of the Sicyopterus genus to settlement and life in tropical insular river systems.

No antimicrobial peptide has been identified in cephalopods to date. Annotation of transcriptomes or genomes using basic local alignment Search Tool failed to yield any from sequence identities. Therefore, we searched for antimicrobial sequences in the cuttlefish (Sepia officinalis) database by in silico analysis of a transcriptomic database. Using an original approach based on the analysis of cysteine-free antimicrobial peptides selected from our Antimicrobial Peptide Database (APD3), the online prediction tool of the Collection of Anti-Microbial Peptides (CAMPR3), and a homemade software program, we identified potential antibacterial sequences. Nine peptides less than 25 amino acids long were synthesized. The hydrophobic content of all nine of them ranged from 30 to 70\%, and they could form alpha-helices. Three peptides possessed similarities with piscidins, one with BMAP-27, and five were totally new. Their antibacterial activity was evaluated on eight bacteria including the aquatic pathogens Vibrio alginolyticus, Aeromonas salmonicida, or human pathogens such as Salmonella typhimurium, Listeria monocytogenes, or Staphylococcus aureus. Despite the prediction of an antimicrobial potential for eight of the peptides, only two-GR21\ and KT19-inhibited more than one bacterial strain with minimal inhibitory concentrations below 25\ {\textmu}M. Some sequences like VA20\ and FK19\ were hemolytic, while GR21\ induced less than 10\% of hemolysis on human blood cells at a concentration of 200\ {\textmu}M. GR21\ was the only peptide derived from a precursor with a signal peptide, suggesting a real role in cuttlefish immune defense.

In intertidal sediments, circadian oscillations (i.e., tidal and diel rhythms) and/or depth may affect prokaryotic activity. However, it is difficult to distinguish the effect of each single force on active community changes in these natural and complex intertidal ecosystems. Therefore, we developed a tidal mesocosm to control the tidal rhythm and test whether diel fluctuation or sediment depth influence active prokaryotes in the top 10\ cm of sediment. Day- and nighttime emersions were compared as they are expected to display contrasting conditions through microphytobenthic activity in five different sediment layers. A multiple factor analysis revealed that bacterial and archaeal 16S ribosomal RNA (rRNA) transcript diversity assessed by pyrosequencing was similar between day and night emersions. Potentially active benthic Bacteria were highly diverse and influenced by chlorophyll a and phosphate concentrations. While in oxic and suboxic sediments, Thaumarchaeota Marine Group I (MGI) was the most active archaeal phylum, suggesting the importance of the nitrogen cycle in muddy sediments, in anoxic sediments, the mysterious archaeal C3 group dominated the community. This work highlighted that active prokaryotes organize themselves vertically within sediments independently of diel fluctuations suggesting adaptation to physicochemical-specific conditions associated with sediment depth.

Aquaculture production is expected to double by 2030, and demands for aquafeeds and raw materials are expected to increase accordingly. Sustainable growth of aquaculture will require the development of highly nutritive and functional raw materials to efficiently replace fish meal. Enzymatic hydrolysis of marine and aquaculture raw materials could bring new functionalities to finished products. The aim of this study was to determine the zootechnical and transcriptomic performances of protein hydrolysates of different origins (tilapia, shrimp, and a combination of the two) in European seabass (Dicentrarchux labrax) fed a low fish meal diet (5\%), for 65\ days.

Results

Results were compared to a positive control fed with 20\% of fish meal. Growth performances, anterior intestine histological organization and transcriptomic responses were monitored and analyzed. Dietary inclusion of protein hydrolysates in the low fish meal diet restored similar growth performances to those of the positive control. Inclusion of dietary shrimp hydrolysate resulted in larger villi and more goblet cells, even better than the positive control. Transcriptomic analysis of the anterior intestine showed that dietary hydrolysate inclusion restored a pattern of intestinal gene expression very close to the pattern of the positive control. However, as compared to the low fish meal diet and depending on their origin, the different hydrolysates did not modulate metabolic pathways in the same way. Dietary shrimp hydrolysate inclusion modulated more metabolic pathways related to immunity, while nutritional metabolism was more impacted by dietary tilapia hydrolysate. Interestingly, the combination of the two hydrolysates enhanced the benefits of hydrolysate inclusion in diets: more genes and metabolic pathways were regulated by the combined hydrolysates than by each hydrolysate tested independently.

Conclusions

Protein hydrolysates manufactured from aquaculture by-products are promising candidates to help replace fish meal in aquaculture feeds without disrupting animal metabolism and performances.

In the current context of the anthropocene, the original habitats of many species have been modified or destroyed. Animals may be forced to move from their original habitats, either to refuge habitats that are suboptimal natural habitats, or to substitution habitats that are anthropogenic. The quality of refuge habitats may be lower than that of the original ones, whereas substitution habitats may be of a similar or even better quality. Here, we test this hypothesis empirically, using the example of coastal populations of the bluethroat, Luscinina svecica namnetum. In a radio-tracking survey, we compared the home-range sizes (considered here a proxy of habitat quality) of the breeding males in their original (coastal saltmarshes), refuge (inland reedbeds) and substitution (coastal salinas) habitats. We found that home ranges are up to 15 times larger in the substitution habitat than in the original one, and intermediate in the refuge habitat, suggesting that substitution habitats have the lowest quality and original habitats the highest. To date, most studies and
conservation programs related to this species have focused on its substitution habitats. This result challenges the interest of focusing on anthropogenic habitats when studying and conserving such a species, because such habitats may only be low-quality substitutes.

Artificial structures in ports are commonly colonized by non-indigenous epifauna that tolerate high pollution levels. Bioconstructions built by alien species may offer sheltered microhabitats for motile (vagile) animals but biofouling often becomes detrimental to human activities. In this context, the present study provides an inventory of 1) the extent of biofouling related to the alien Polychaeta Ficopomatus enigmaticus on hard structures of marinas in Normandy, France, and 2) the biodiversity of sessile (attached) or vagile (motile) fauna associated with these {\textquotedblleft}reefs{\textquotedblright}, including both native and alien species. Reefs built by F. enigmaticus were found in 6 out of 12 marinas with oligohaline-mesohaline waters. Significant differences in the total volume of biofouling were found among sites, with maximum values observed in Honfleur{\textquoteright}s old basin (459.52 mL per 0.04 m2). Ficopomatus enigmaticus greatly dominated the sessile invertebrate community both in volume (74{\textendash}100\%) and weight (70{\textendash}100\%) in 5 out of 6 marinas. The fouling formed by 5 alien species was colonized by 15 motile invertebrate taxa, including 3 cryptogenic or alien species. The alien crab Rhithropanopeus harrisi displayed the highest frequency of occurrence (\>80\%) and mean density (\>300 ind m-2), and the global densities of sessile (except F. enigmaticus) and motile fauna were significantly correlated (r = 0.824; p \< 0.05). While motile fauna density was also significantly correlated with the biovolume of B. improvisus and M. leucophaeata, it was not with F. enigmaticus (r = 0.421; p \> 0.05). In line with previous studies, these results suggest that F. enigmaticus acts as an engineer offering shelter for reef-associated organisms. In addition, results suggest that at the regional scale, inter-site differences in motile fauna may reflect differences in environmental parameters such as salinity. The presence of F. enigmaticus at low salinity levels led to assess its potential distribution at the scale of the European coasts, suggesting that in the context of climate change, favorable conditions for spawning (\>18 {\textdegree}C) will likely expand towards the North, and particularly in the eastern and northern Baltic Sea.

In parallel to phytoplankton community dynamics, transparent exopolymeric particles (TEP) and exopolymeric
substances (EPS) were investigated along the salinity gradient of a temperate estuary (Seine estuary, Normandy,
France) over the course of a year. The phytoplankton community was mainly dominated by marine diatom
species (especially Skeletonema sp., Nitzschia sp., and Paralia sulcata) associated with a spring bloom of picoeukaryotes
and the development of Cryptophyceae in summer. The decreases in species richness and salinity were
correlated along the estuary and a significant exponential relationship between species richness and primary
production was identified. Concentrations of TEP and EPS (soluble and bound carbohydrates) are highly dynamic
in this estuary and can reach respectively 69 mgC L-1, and 33 mgC L-1. TEP distribution was mainly
related to physical factors (hydrodynamics, maximum turbidity zone formation and sediment resuspension)
probably produced by stressed or dying phytoplankton, while EPS appeared to be excreted during the phytoplankton
spring bloom. Soluble and bound EPS appear to be related to Skeletonema sp. and Cryptophyceae occurrences.
This paper presents the dynamic pattern of these carbon pools, which play an important role in the
trophic network and influence the flocculation processes involved in the fate of both organic and inorganic
matter.

The formation of the molluscan shell nacre is regulated to a large extent by a matrix of extracellular macromolecules that are secreted by the shell-forming tissue, the mantle. This so-called {\textquoteleft}calcifying matrix{\textquoteright} is a complex mixture of proteins, glycoproteins and polysaccharides that is assembled and occluded within the mineral phase during the calcification process. Better molecular-level characterization of the substances that regulate nacre formation is still required. Notable advances in expressed tag sequencing of freshwater mussels, such as Elliptio complanata and Villosa lienosa, provide a pre-requisite to further characterize bivalve nacre proteins by a proteomic approach. In this study, we have identified a total of 48 different proteins from the insoluble matrices of the nacre, 31 of which are common to both E. complanata and V. lienosa. A few of these proteins, such as PIF, MSI60, CA, shematrin-like, Kunitz-like, LamG, chitin-binding-containing proteins, together with A-, D-, G-, M- and Q-rich proteins, appear to be analogues, if not true homologues, of proteins previously described from the pearl oyster or the edible mussel nacre matrices, thus forming a remarkable list of deeply conserved nacre proteins. This work constitutes a comprehensive nacre proteomic study of non-pteriomorphid bivalves that has enabled us to describe the molecular basis of a deeply conserved biomineralization toolkit among nacreous shell-bearing bivalves, with regard to proteins associated with other shell microstructures, with those of other mollusc classes (gastropods, cephalopods) and, finally, with other lophotrochozoans (brachiopods).

ABSTRACT: Arctic coastal ecosystems are likely to be strongly affected by predicted environmental changes such as sea-ice decline and increase in freshwater input and turbidity. These changes are expected to impact primary production dynamics and consequently benthic consumers. The trophic relationship between primary producers and benthic primary consumers were compared in 2 Arctic fjords with different seasonal ice-cover: Young Sound (NE Greenland, a high-Arctic fjord) and Kongsfjorden (Svalbard Archipelago, a sub-Arctic fjord). For comparison, we selected the filter-feeding bivalve Astarte moerchi (belonging to the complex A. borealis), which has a broad geographical distribution in the Arctic. The bivalve digestive glands and food sources were characterized with fatty acids (FAs), bulk stable isotopes, and compound-specific stable isotopes of individual FAs. Our results suggest that diatoms of pelagic and/or benthic origin are the main contributors to the A. moerchi diet in Young Sound and make up a less important fraction of the diet in the Kongsfjorden population. A contribution by sympagic diatoms is clearly excluded in the sub-Arctic fjord and needs to be further assessed in the Arctic fjord. The A. moerchi diet in sub-Arctic Kongsfjorden is more diversified, varies with season, and has contributions from dinoflagellates and macroalgal detritus. These results, together with higher concentrations of total FAs in the Young Sound population, demonstrated and characterized the trophic plasticity of this bivalve species. Based on these results, we discuss potential effects of environmental factors (shifts in trophic resources, increase in turbidity) for A. moerchi populations in changing Arctic ecosystems.

Three species of skate, Bathyraja eatonii, B. irrasa and B. murrayi, are commonly taken as incidental by-catch in Patagonian toothfish (Dissostichus eleginoides) longline and trawl fisheries, and the mackerelicefish (Champsocephalus gunnari) trawl fishery on the Kerguelen Plateau (KP) in the southern IndianOcean. Data from fishery observations for 1997{\textendash}2014 shows that the three skates were widely distributedacross the Kerguelen Plateau, showing different spatial distributions, linked mainly with depth. Off HeardIsland and McDonald Islands (HIMI), in the southern part of the KP, B. eatonii and B. irrasa were mostabundant to the north and northwest of Heard Island, out to the edge of the Australian Exclusive EconomicZone (EEZ), and were caught down to depths of 1790 m and 2059 m respectively. The smallest species, B.murrayi, occurred mainly in the shallower waters down to 550 m, and was most abundant to the northand northeast, close to Heard Island. Around Kerguelen Islands, in the northern part of the KP, skateswere most abundant between the 500 m and 1000 m contours circling and extending from the islands.Catch rates were modelled using zero-inflated GAMs and GLMs. The catch rates of skates from thetrawl fisheries in the Australian EEZ surrounding Heard Island and McDonald Islands have shown littleevidence of depletion on the main trawl fishing grounds, although there is evidence of a decrease inthe average total length of B. eatonii. The marine reserves and the conservation measures employed bythe Commission for the Conservation of Antarctic Marine Living Resources in the HIMI fisheries, appearto provide effective protection for the skates, at least in the shallower waters where the trawl fisheriesoperate. B. irrasa taken in the deeper waters where longline fishing occurs have shown a slight declinein catch rate over the years of the HIMI fishery. Although all skates are returned to the water from thisfishery, survival rates are unknown and careful monitoring should continue to assess the status of thesestocks. There appears to be little change in the abundance of the skate species at Kerguelen in the timeperiod.This study provides the first review of skate by-catch across both the HIMI and Kerguelen fisheries.Ongoing monitoring of species specific by-catch levels and further research to determine the importantlife history parameters of these species are required, particularly for B. irrasa which is taken in both trawland longline fisheries.

Tropical rainforests harbor extraordinary biodiversity. The Amazon basin is thought to hold 30\% of all river fish species in the world. Information about the ecology, reproduction, and recruitment of most species is still lacking, thus hampering fisheries management and successful conservation strategies. One of the key understudied issues in the study of population dynamics is recruitment. Fish larval ecology in tropical biomes is still in its infancy owing to identification difficulties. Molecular techniques are very promising tools for the identification of larvae at the species level. However, one of their limits is obtaining individual sequences with large samples of larvae. To facilitate this task, we developed a new method based on the massive parallel sequencing capability of next generation sequencing (NGS) coupled with hybridization capture. We focused on the mitochondrial marker cytochrome oxidase I (COI). The results obtained using the new method were compared with individual larval sequencing. We validated the ability of the method to identify Amazonian catfish larvae at the species level and to estimate the relative abundance of species in batches of larvae. Finally, we applied the method and provided evidence for strong temporal variation in reproductive activity of catfish species in the Ucayal{\'\i} River in the Peruvian Amazon. This new time and cost effective method enables the acquisition of large datasets, paving the way for a finer understanding of reproductive dynamics and recruitment patterns of tropical fish species, with major implications for fisheries management and conservation.

Eleven systems (two littoral systems, eight embayments and semi-enclosed systems and one estuary) distributed along the three maritime fa{\c c}ades of France were studied for two to eight years in order to quantify the relative contribution of organic matter sources to the surface-water POM pool in coastal systems. This study was based on carbon and nitrogen elemental and isotopic ratios, used for running mixing models. The POM of the estuary is dominated by terrestrial material (93\% on average), whereas the POM of the other systems is dominated by phytoplankton (84\% on average). Nevertheless, for the latter systems, the POM composition varies in space, with (1) systems where POM is highly composed of phytoplankton (>=93\%), (2) systems characterized by a non-negligible contribution of benthic (8{\textendash}19\%) and/or river (7{\textendash}19\%) POM sources, and (3) the Mediterranean systems characterized by the contribution of diazotroph organisms (ca. 14\%). A continent-to-ocean gradient of river and/or benthic POM contribution is observed. Finally, time series reveal (1) seasonal variations of POM composition, (2) differences in seasonality between systems, and (3) an inshore-offshore gradient of seasonality within each system that were sampled at several stations. Spatial and seasonal patterns of POM composition are mainly due to local to regional processes such as hydrodynamics and sedimentary hydrodynamic (e.g. resuspension processes, changes in river flows, wind patterns influencing along-shore currents) but also due to the geomorphology of the systems (depth of the water column, distance to the shore). Future studies investigating the link between these forcings and POM composition would help to better understand the dynamics of POM composition in coastal systems. {\textcopyright} 2017 Elsevier Ltd}, keywords = {bacterium, benthos, biogeochemistry, Biological materials, C and n stable isotopes, C:N ratio, Carbon, carbon isotope, Coastal systems, coastal zone, Fluid dynamics, France, geomorphology, Hydrodynamics, Isotopes, isotopic ratio, Mediterranean sea, Meta analysis, meta-analysis, Mixing, Mixing models, nitrogen isotope, Organic compounds, particulate organic matter, Particulate organic matters, Phytoplankton, prokaryote, Rivers, seasonality, spatiotemporal analysis, stable isotope, Surface water, Surface waters, terrestrial deposit, Time series}, issn = {00796611}, doi = {10.1016/j.pocean.2017.03.001}, url = {https://www.sciencedirect.com/science/article/abs/pii/S0079661116301914}, author = {Li{\'e}nart, Camilla and Savoye, Nicolas and Bozec, Yann and Elsa Breton and Conan, Pascal and David, Val{\'e}rie and Eric Feunteun and Karine Granger{\'e} and Kerherv{\'e}, P. and Lebreton, B. and S{\'e}bastien Lefebvre and St{\'e}phane L{\textquoteright}Helguen and Mousseau, Laure and Raimbault, P and Richard, P. and Riera, P. and Sauriau, P.-G. and Gauthier Schaal and Aubert, F. and Aubin, S. and Bichon, S. and Boinet, C. and Bourasseau, L. and Br{\'e}ret, M. and Caparros, J. and Cariou, T. and Charlier, K. and Claquin, P. and Vincent Cornille and Corre, A.-M. and Costes, L. and Crispi, O. and Muriel Crouvoisier and Czamanski, M. and Del Amo, Y. and Derriennic, H. and Dindinaud, F. and Durozier, M. and Hanquiez, V. and Antoine Nowaczyk and Devesa, J. and Ferreira, S. and Fornier, M. and Garcia, F. and Garcia, N. and Geslin, S. and Emilie Grossteffan and Gueux, A. and Guillaudeau, J. and Guillou, G. and Joly, O. and Lachauss{\'e}e, N. and Lafont, M. and Lamoureux, J. and Lecuyer, E. and Lehodey, J.-P. and Lemeille, D. and Leroux, C. and Mac{\'e}, E. and Maria, E. and Pineau, P. and Petit, F. and Pujo-Pay, M. and Rimelin-Maury, P. and Sultan, E.} } @article {5136, title = {Dynamics of phytoplankton productivity and exopolysaccharides (EPS and TEP) pools in the Seine Estuary (France, Normandy) over tidal cycles and over two contrasting seasons}, journal = {Marine Environmental Research}, year = {2017}, month = {09/2017}, author = {Morelle, J{\'e}r{\^o}me and Mathilde Schapira and Pascal Claquin} } @article {4595, title = {Dating of the Limnadiidae family suggests an American origin of Eulimnadia}, journal = {Hydrobiologia}, volume = {773}, year = {2016}, month = {02/2016}, pages = {149{\textendash}161}, abstract = {

The spinicaudatan clam shrimp is a group of branchiopod crustaceans that has existed as far back as the Devonian and well-preserved fossils are known. Evidence of monophyly exists for only one family (Limnadiidae), which has a worldwide distribution and morphological conservatism. The evolutionary relationships among genera and diversification mechanisms are not deeply resolved as well as origin of the genus Eulimnadia. To address these issues, we constructed phylogenies of limnadiid clam shrimp, with both Bayesian inference and maximum likelihood methods to infer limnadiid evolutionary relationships. We then performed dated phylogenies using a relaxed clock of the Spinicaudata using fossil calibrations. Divergence date estimates show a perfect match with the break up of the Pangaea that could explain current limnadiid distributions; however the genus Eulimnadia apparently diverged 30 Ma ago. Eulimnadia phylogeography suggests an American origin and ecological patterns were analyzed to propose hypotheses on its origin and spread. This genus also shows a strong dispersive capacity, which could be explained by its reproduction modalities (androdioecy). This study and this first phylogeny with fossil calibration date the current distribution of Spinicaudata and reveal congruence with continental drift, except for Eulimnadia.

SUMMARY

1. The effect of drying events on aquatic biodiversity is still overlooked in wet Neotropical systems. Yet, the responses of local communities and metacommunities in these biodiversity hotspots may differ from what is reported in other areas.
2. We addressed the effect of drying events on local and regional fish and macroinvertebrate communities in the headwaters of the Chipiriri River basin, in the wet Neotropical piedmont of Bolivia. According to current knowledge in intermittent rivers and ephemeral streams (IRES) ecology, we predicted that intermittent (INT) sites would harbour lower a-diversity, but higher b-diversity, than perennial (PER) sites, due to local, negative effect of drying combined with the existence of multiple recovery stages at the network scale.

3. Although habitat variables were similar between INT and PER sites, local and regional diversity patterns differed. Local invertebrate communities were not different between site types as soon as 4{\textendash}6 weeks after flow resumption. The proximity of colonist sources and frequent rainfall probably enhanced persistence through dry periods and high resilience. In contrast, fish communities were still poorer at INT than PER sites, indicating they were still in the process of recolonising upstream INT reaches.

4. b-diversity analyses confirmed that invertebrate and fish metacommunities were not at the same recovery stage because (i) b-diversity of invertebrates was best explained by physical and environmental distances at both INT and PER sites, whereas that of fish was explained only by physical distances at INT sites; (ii) fish b-diversity was higher at INT than at PER sites, but invertebrate b-diversity was similar; and (iii) physical distances were correlated with the turnover component of invertebrate b-diversity but with the nestedness component for fish.

5. Exploring regional community patterns in IRES and across biota with different dispersal abilities and modes can advance metacommunity theory and improve our ability to predict local community composition in dynamic ecosystems.

is a powerful tool for the high-precision measurement of the isotopic ratios of many elements in geological
samples, with the isotope ratio (11B/10B) of boron being used as an indicator of the pH of oceanic waters. Most geological
samples or standards are polished and ablation occurs on flat surfaces. However, the shape and the irregularities of
marine biocarbonates (e.g., corals, foraminifera) can make precise isotopic measurements of boron difficult. Even after
polishing, the porosity properties and the presence of holes or micro-fractures affect the signal and the isotopic ratio
when ablating the material, especially in raster mode.
METHODS: The effect of porosity and of the crater itself on the 11B signal and the isotopic ratio acquired by LA-MCICPMS
in both raster and spot mode was studied. Characterization of the craters was then performed with an optical
profilometer to determine their shapes and depths. Surface state effects were examined by analyzing the isotopic
fractionation of boron in silicate (NIST-SRM 612 and 610 standards) and in carbonate (corals).
RESULTS: Surface irregularities led to a considerable loss of signal when the crater depth exceeded 20 μm. The stability
and precision were degraded when ablation occurred in a deep cavity. The effect of laser focusing and of blank correction
was also highlighted and our observations indicate that the accuracy of the boron isotopic ratio does not depend on the
shape of the surface. After validation of the analytical protocol for boron isotopes, a raster application on a Porites coral,
which grew for 18 months in an aquarium after field sampling, was carried out.
CONCLUSIONS: This original LA-MC-ICPMS study revealed a well-marked boron isotope ratio temporal variability,
probably related to growth rate and density changes, irrespective of the pH of the surrounding seawater.}, doi = {10.1002/rcm.7448}, url = {http://doi.wiley.com/10.1002/rcm.7448}, author = {Thil, Fran{\c c}ois and Blamart, Dominique and Assailly, Caroline and Claire E.

The development of several cephalopods among them Sepia officinalis (Linnaeus, 1758) has been very carefully described by Naef in the early 20th century. Here an illustrated developmental table of Sepia officinalis is proposed with a morphological description of each stage. The 30 stages are grouped into five steps of development: cleavage (stages 1 to 9), gastrulation (stages 10 to 13), organogenesis, plane phase (stages 14 to 18), organogenesis, extension phase (stages 19 to 22) and organogenesis, growth phase (stages 23 to 30), when the embryo has acquired the general adult conformation. For each stage, morphological identification criteria are proposed in order that this table is used as a lab tool for cephalopod researchers interested in development.

In order to investigate the mechanisms of final maturation and capacitation of spermatozoa in Pecten maximus, we used a 2D proteomic approach coupled with MALDI-TOF/TOF mass spectrometry (MS) and bioinformatics search against the Pecten database, to set up a reference map of the proteome of spawned spermatozoa, and identified 133 proteins on the basis of the EST database. These proteins are mainly involved in energy production, ion and electron transport (44\%), cell movement (22\%) and developmental processes (10\%). Comparison between proteomes of spermatozoa collected before and after transit through the genital ducts of P. maximus led to the identification of differentially expressed proteins. Most of them are associated with energy metabolism (aconitate hydratase, malate dehydrogenase, glyceraldehyde-3-phosphate dehydrogenase), indicating important modifications of energy production during transit in gonoducts, potentially linked with acquisition of sperm motility. Three proteins involved in cell movement (Tektin-2, tubulin and microtubule-associated protein RP/EB family member 3) were down-regulated in spermatozoa stripped from the gonad. 40S ribosomal protein SA, involved in maturation of 40S ribosomal subunits, was also found to be down-regulated in spermatozoa obtained by induced spawning, suggesting reduction of the effi- ciency of RNA translation, a characteristic of late spermatozoon differentiation. These results confirm that maturation processes of P. maximus spermatozoa during transit through the gonoduct involve RNA translation, energy metabolism and structural proteins implicated in cell movement. Spermatozoa maturation processes clearly differ between P. maximus and gonochoric or alternately hermaphroditic bivalves, potentially in relation to reproductive strategies: the final maturation of the spermatozoon along the genital tract probably contributes to reduction of autofertilization in this simultaneously hermaphroditic species

δ(15)N of annual (Ulva sp., Porphyra sp.) and perennial intertidal seaweed species (Chondrus crispus, Fucus sp.) collected on 17 sampling points along the French coast of the English Channel in 2012 and 2013 were assessed on their suitability as bioindicators of N pollution in coastal areas. A sine function applied for δ(15)N time series data showed for all the species the same seasonal trend with lowest δ(15)N values in April and highest in summer but with no significant interspecific differences of amplitude (α) and phase angle (ϕ). This model provides a useful tool for monitoring the inter-annual changes of N pollution. An interspecific variability of δ(15)N values was observed, probably due to their tolerance to emersion. An in vitro study for comparing the kinetic acquisition of the isotopic signal and N uptake mechanisms of each species underlined the influence of algal physiology on the δ(15)N interspecific variability.

Fluctuations in the stress level of an organism are expressed in behavioural and molecular changes that can affect its ecology and survival. Our knowledge of thermal adaptations in deep-sea organisms is very limited, and this study investigates the critical thermal maximum (CTmax) and the heat-shock response (HSR) in the deep-sea crab Chaceon affinis commonly found in waters of the North East Atlantic. A mild but significant HSR in C. affinis was noted and one of the lowest CTmax known amongst Crustacea was revealed (27.5 {\textdegree}C at 0.1 MPa; 28.5 {\textdegree}C at 10 MPa). The thermal sensitivity of this species appears to be reduced at in situ pressure (10 MPa), given the slightly higher CTmax and the significant 3-fold induction of stress genes hsp70 form 1 and hsp70 form 2. Although C. affinis deep-sea habitat is characterized by overall low temperature this species appears to have retained its ability to induce a HSR. This capability may be linked with C. affinis{\textquoteright} occasional exploitation of warmer and thermally instable hydrothermal vent fields, where it has been found foraging for food.

Pituitary gonadotropins, FSH and LH, control gonad activity in vertebrates, via binding to their respective receptors, FSHR and LHR, members of GPCR superfamily. Until recently, it was accepted that gnathostomes possess a single FSHR and a single LHR, encoded by fshr and lhcgr genes. We reinvestigated this question, focusing on vertebrate species of key-phylogenetical positions. Genome analyses supported the presence of a single fshr and a single lhcgr in chondrichthyans, and in sarcopterygians including mammals, birds, amphibians and coelacanth. In contrast, we identified a single fshr but two lhgcr in basal teleosts, the eels. We further showed the coexistence of duplicated lhgcr in other actinopterygians, including a non-teleost, the gar, and other teleosts, e.g. Mexican tetra, platyfish, or tilapia. Phylogeny and synteny analyses supported the existence in actinopterygians of two lhgcr paralogs (lhgcr1/ lhgcr2), which do not result from the teleost-specific whole-genome duplication (3R), but likely from a local gene duplication that occurred early in the actinopterygian lineage. Due to gene losses, there was no impact of 3R on the number of gonadotropin receptors in extant teleosts. Additional gene losses during teleost radiation, led to a single lhgcr (lhgcr1 or lhgcr2) in some species, e.g. medaka and zebrafish. Sequence comparison highlighted divergences in the extracellular and intracellular domains of the duplicated lhgcr, suggesting differential properties such as ligand binding and activation mechanisms. Comparison of tissue distribution in the European eel, revealed that fshr and both lhgcr transcripts are expressed in the ovary and testis, but are differentially expressed in non-gonadal tissues such as brain or eye. Differences in structure-activity relationships and tissue expression may have contributed as selective drives in the conservation of the duplicated lhgcr. This study revises the evolutionary scenario and nomenclature of gonadotropin receptors, and opens new research avenues on the roles of duplicated LHR in actinopterygians.

BACKGROUND: A comparative thermal tolerance study was undertaken on two sister species of Euphausiids (Antarctic krills) Euphausia superba and Euphausia crystallorophias. Both are essential components of the Southern Ocean ecosystem, but occupy distinct environmental geographical locations with slightly different temperature regimes. They therefore provide a useful model system for the investigation of adaptations to thermal tolerance.

METHODOLOGY/PRINCIPAL FINDING: Initial CTmax studies showed that E. superba was slightly more thermotolerant than E. crystallorophias. Five Hsp70 mRNAs were characterized from the RNAseq data of both species and subsequent expression kinetics studies revealed notable differences in induction of each of the 5 orthologues between the two species, with E. crystallorophias reacting more rapidly than E. superba. Furthermore, analyses conducted to estimate the evolutionary rates and selection strengths acting on each gene tended to support the hypothesis that diversifying selection has contributed to the diversification of this gene family, and led to the selective relaxation on the inducible C form with its possible loss of function in the two krill species.

CONCLUSIONS: The sensitivity of the epipelagic species E. crystallorophias to temperature variations and/or its adaptation to cold is enhanced when compared with its sister species, E. superba.

In this study, a model based on primary cultured haemocytes from the gastropod mollusc Haliotis tuberculata was established to investigate the effects of cadmium chloride in vitro. Cells were exposed for 24\ h to CdCl2 concentrations of 0, 1 and 100\ μg\ ml(-1). The effects of cadmium on haemocyte parameters were investigated using morphological, spectrophotometric and flow cytometry analysis. Results showed that cadmium has no significant effects on cell viability and phagocytotic activity under the tested conditions. However, haemocytes became more rounded after cadmium exposure, which could explain the significant decrease of cell area beginning at 1\ μg\ ml(-1) of CdCl2.

Dopaminergic (DA) neurons located in the preoptico-hypothalamic region of the brain exert a major neuroendocrine control on reproduction, growth and homeostasis by regulating the secretion of anterior pituitary (or adenohypophysis) hormones. Here, using a retrograde tract tracing experiment, we identified the neurons playing this role in the zebrafish. The DA cells projecting directly to the anterior pituitary are localized in the most anteroventral part of the preoptic area, and we named them preoptico-hypophyseal DA (POHDA) neurons. During development, these neurons do not appear before 72 hours post fertilization (hpf) and are the last dopaminergic cell group to differentiate. We found that the number of neurons in this cell population continues to increase life-long, proportionally to the growth of the fish. BrdU incorporation analysis suggested that this increase is due to continuous neurogenesis and not due to a phenotypic change in already existing neurons. Finally, expression profiles of several genes (foxg1a, dlx2a and nr4a2a/b) were different in the POHDA compared to the adjacent suprachiasmatic DA neurons, suggesting that POHDA neurons develop as a distinct DA cell population in the preoptic area. This study offers some insights into the regional identity of the preoptic area and provides the first bases for future functional genetic studies on the development of DA neurons controlling anterior pituitary functions.

A manipulative field experiment in an intermittent alluvial river}, journal = {Freshwater Biology}, year = {2015}, abstract = {

ABSTRACT: 1. In river systems, aquatic invertebrate communities are surprisingly persistent over time and generally recover quickly from disturbances. Drift has long been viewed as the primary process promoting this resilience, and it plays a important role in predictive models of community composition and concepts in lotic ecology. More recently, other processes such as vertical migration from the hyporheic zone, aerial oviposition from distant refuges and the use of resistance forms (e.g. diapause) have received greater recognition and support for their importance. 2. In this study, the view that drift is the primary process promoting invertebrate community resilience was challenged in an intermittent alluvial river using reach-scale flow manipulations. First, six treatment channels were completely dried for 1 week, while three others were left flowing to be used as controls. Second, flow was re-established in channels and drift was either allowed or blocked for a 4-week period. Third, during this period the resilience of community structure, composition and function was compared between treatments, and the potential for colonisation from the drift, hyporheic zone, aerial oviposition and resistance forms was measured. 3. Communities recovered after only 2 weeks in all of the previously dried channels, and contrary to our hypotheses, invertebrate community structure, composition and functional trait composition were not altered by blocking drift, indicating it was not the primary process promoting resilience in this river. 4. Three lines of evidence suggested colonisation from the hyporheic zone and not aerial oviposition nor resistance forms promoted resilience following rewetting including the following: (i) finding all common benthic taxa in the hyporheic zone during the drying event, (ii) a distinct decrease in invertebrate size upon rewetting in all treatment channels and (iii) a negative correlation between resilience and water table depth. 5. This experiment highlighted the potential importance of the hyporheic zone as a key source of colonisation in alluvial rivers and emphasises the need for a three-dimensional perspective when considering community resilience in rivers. Adaptive management approaches are needed to direct attention to sources (e.g. hyporheic zone) that are essential to promoting community resilience in rivers facing increased pressures due to climate change, water abstraction and flow regime alteration.

Since its discovery in mammals as a key-hormone in reproduction and metabolism, leptin has been identified in an increasing number of tetrapods and teleosts. Tetrapods possess only one leptin gene, while most teleosts possess two leptin genes, as a result of the teleost third whole genome duplication event (3R). Leptin acts through a specific receptor (LEPR). In the European and Japanese eels, we identified two leptin genes, and for the first time in vertebrates, two LEPR genes. Synteny analyses indicated that eel LEPRa and LEPRb result from teleost 3R. LEPRb seems to have been lost in the teleost lineage shortly after the elopomorph divergence. Quantitative PCRs revealed a wide distribution of leptins and LEPRs in the European eel, including tissues involved in metabolism and reproduction. Noticeably, leptin1 was expressed in fat tissue, while leptin2 in the liver, reflecting subfunctionalization. Four-month fasting had no impact on the expression of leptins and LEPRs in control European eels. This might be related to the remarkable adaptation of silver eel metabolism to long-term fasting throughout the reproductive oceanic migration. In contrast, sexual maturation induced differential increases in the expression of leptins and LEPRs in the BPG-liver axis. Leptin2 was strikingly upregulated in the liver, the central organ of the reproductive metabolic challenge in teleosts. LEPRs were differentially regulated during sexual maturation, which may have contributed to the conservation of the duplicated LEPRs in this species. This suggests an ancient and positive role of the leptin system in the vertebrate reproductive function. This study brings new insights on the evolutionary history of the leptin system in vertebrates. Among extant vertebrates, the eel represents a unique case of duplicated leptins and leptin receptors as a result of 3R.

Bacterial symbiont transmission is a key step in the renewal of the symbiotic interaction at each host generation, and different modes of transmission can be distinguished. Vesicomyidae are chemosynthetic bivalves from reducing habitats that rely on symbiosis with sulfur-oxidizing bacteria, in which two studies suggesting vertical transmission of symbionts have been published, both limited by the imaging techniques used. Using fluorescence in situ hybridization and transmission electron microscopy, we demonstrate that bacterial symbionts of Isorropodon bigoti, a gonochoristic Vesicomyidae from the Guiness cold seep site, occur intracellularly within female gametes at all stages of gametogenesis from germ cells to mature oocytes and in early postlarval stage. Symbionts are completely absent from the male gonad and gametes. This study confirms the transovarial transmission of symbionts in Vesicomyidae and extends it to the smaller species for which no data were previously available.

The diversity of sponge-associated fungi has been poorly investigated in remote geographical areas like Antarctica. In this study, 101 phenotypically different fungal isolates were obtained from 11 sponge samples collected in King George Island, Antarctica. The analysis of ITS sequences revealed that they belong to the phylum Ascomycota. Sixty-five isolates belong to the genera Geomyces, Penicillium, Epicoccum, Pseudeurotium, Thelebolus, Cladosporium, Aspergillus, Aureobasidium, Phoma, and Trichocladium but 36 isolates could not be identified at genus level. In order to estimate the potential of these isolates as producers of interesting bioactivities, antimicrobial, antitumoral and antioxidant activities of fungal culture extracts were assayed. Around 51\% of the extracts, mainly from the genus Geomyces and non identified relatives, showed antimicrobial activity against some of the bacteria tested. On the other hand, around 42\% of the extracts showed potent antitumoral activity, Geomyces sp. having the best performance. Finally, the potential of the isolated fungi as producers of antioxidant activity seems to be moderate. Our results suggest that fungi associated with Antarctic sponges, particularly Geomyces, would be valuable sources of antimicrobial and antitumoral compounds. To our knowledge, this is the first report describing the biodiversity and the metabolic potential of fungi associated with Antarctic marine sponges.

Since the initial characterization of the cardioexcitatory peptide FMRFamide in the bivalve
mollusk Macrocallista nimbosa, a great number of FMRFamide-like peptides (FLPs) have
been identified in mollusks. FLPs were initially isolated and molecularly characterized in
model mollusks using biochemical methods. The development of recombinant technologies
and, more recently, of genomics has boosted knowledge on their diversity in various
mollusk classes. Today, mollusk FLPs represent approximately 75 distinct RFamide peptides
that appear to result from the expression of only five genes: the FMRFamide-related
peptide gene, the LFRFamide gene, the luqin gene, the neuropeptide F gene, and the cholecystokinin/
sulfakinin gene. FLPs display a complex spatiotemporal pattern of expression
in the central and peripheral nervous system.Working as neurotransmitters, neuromodulators,
or neurohormones, FLPs are involved in the control of a great variety of biological
and physiological processes including cardiovascular regulation, osmoregulation, reproduction,
digestion, and feeding behavior. From an evolutionary viewpoint, the major challenge
will then logically concern the elucidation of the FLP repertoire of orphan mollusk classes
and the way they are functionally related. In this respect, deciphering FLP signaling pathways
by characterizing the specific receptors these peptides bind remains another exciting
objective.

UNLABELLED: We characterized the proteome of the posterior salivary glands of the cephalopod S. officinalis by combining de novo RNA sequencing and mass spectrometry. In silico analysis of the transcriptome revealed the occurrence of three main categories of proteins: enzymes, immune factors and toxins. Protein identification by SDS-PAGE and MALDI-TOF/TOF confirmed the occurrence of proteins essential to venom-like enzymes: peptidase S1 under four isoforms, phospholipase A2 and two toxins. The first toxin is a cystein rich secreted protein (CRISP), a common toxin found in all venomous animals. The second one is cephalotoxin, which is specific to decabrachia cephalopods. Secretions of the posterior salivary glands are transported to the cephalopodium; they are involved in prey catching but also in gamete storage, fertilization and egg-laying. The paralyzing activity and the antimicrobial effect of saliva suggest a dual role in predation and in immune defense in cuttlefish.

BIOLOGICAL SIGNIFICANCE: The originality of this study lies in the use of a transcriptomic approach (de novo RNA sequencing) coupled to a proteomic approach to get an overview of posterior salivary glands in S. officinalis. In cephalopods, these glands are involved in predation, more precisely in paralyzing preys and digesting them. Our in silico analysis equally reveals a role in immune defense as observed in mammals{\textquoteright} saliva. Our study also shows the specificity of cuttlefish venom, with the identification of cephalotoxins, proteins that are not found in octopuses. Finally, we show that cuttlefish saliva is a complex mixture that has antibacterial and crippling properties, but no lethal effect.

Kelp ecosystems form widespread underwater forests playing a major role in structuring the biodiversity at a regional scale. Some seaweeds such as Laminaria digitata are also economically important, being exploited for their alginate and iodine content. Although some studies have shown that kelp ecosystems are regressing and that multiple causes are likely to be at the origin of the disappearance of certain populations, the extent to which global climate change may play a role remains speculative. Here we show that many populations of L. digitata along European coasts are on the verge of local extinction due to a climate-caused increase in sea temperature. By modeling the spatial distribution of the seaweed, we evaluate the possible implications of global climate change for the geographical patterns of the species using temperature data from the Coupled Model Intercomparison Project phase 5 (CMIP5). Projections of the future range of L. digitata throughout the 21st century show large shifts in the suitable habitat of the kelp and a northward retreat of the southern limit of its current geographic distribution from France to Danish coasts and the southern regions of the United Kingdom. However, these projections depend on the intensity of warming. A medium to high warming is expected to lead to the extirpation of the species as early as the first half of the 21st century and there is high confidence that regional extinction will spread northwards by the end of this century. These changes are likely to cause the decline of species whose life cycle is closely dependent upon L. digitata and lead to the establishment of new ecosystems with lower ecological and economic values.
