This study aimed to describe the acclimation capacity of sand dollars Echinarachnius parma found in the highly seasonal sub-Arctic archipelago of Saint Pierre and Miquelon. Fatty acid composition was quantified in cell membranes and energy reserve of sand dollars collected at specific stations according to depth and seasons. We hypothesized that perceived temperatures, seasonal thermal conditions and the trophic environment may considerably influence E. parma fatty acid profiles. In the polar fraction, E. parma showed high relative contributions of eicosapentaenoic acid (20:5ω3; 28.5\%) followed by 16:0 (10.83\%), 14:0 (6.67\%) and 18:4ω3 (3.49\%). Whereas variations in 20:5ω3 relative contributions seemed to be mainly related to spawning events, docosahexaenoic acid (22:6ω3; 2.48\%) and arachidonic acid (20:4ω6; 2.49\%) varied according to the thermal gradient of the water column. Furthermore, the seasonal thermal internal wave acting throughout the archipelago appeared to lack sufficient intensity to trigger modifications in the polar concentration in individuals. In the neutral fraction, the strong dominance of diatom markers (20:5ω3; 24.2\% and 16:1ω7; 21.9\%) suggests that the diet of sand dollars mostly reflects the composition of the organic matter available over the sediment. Our study (1) highlights specific fatty acid functions in the metabolic regulation of echinoids, (2) defines the feeding ecology of sand dollars and (3) describes the effects of different thermal conditions on the physiology of locally adapted poikilotherm animals.}, keywords = {Echinarachnius, Feeding ecology, Sand dollars, Thermal acclimation}, issn = {0171-8630}, doi = {10.3354/meps14692}, url = {https://www.int-res.com/abstracts/meps/v747/p83-97/}, author = {Uboldi, Thomas and Bridier, Guillaume and Fr{\'e}d{\'e}ric Olivier and Grall, Jacques and Chauvaud, Laurent and Tremblay, Rejean} } @article {9577, title = {Amphidromous shrimps (Decapoda: Caridea): current knowledge and future research}, journal = {Journal of Crustacean Biology}, volume = {44}, year = {2024}, month = {Feb-09-2024}, type = {Review article}, issn = {0278-0372}, doi = {10.1093/jcbiol/ruae003}, url = {https://academic.oup.com/jcb/article-abstract/44/1/ruae003/7604398?redirectedFrom=fulltext\&login=false}, author = {de Mazancourt, Valentin and Ravaux, Juliette} } @article {9558, title = {Ancestors{\textquoteright} Gift: Parental Early Exposure to the Environmentally Realistic Pesticide Mixture Drives Offspring Phenotype in a Larger Extent Than Direct Exposure in the Pacific Oyster, Crassostrea gigas}, journal = {Environmental Science \& Technology}, year = {2024}, issn = {0013-936X}, doi = {10.1021/acs.est.3c0820110}, url = {https://pubs.acs.org/doi/10.1021/acs.est.3c08201}, author = {Sol-Dourdin, Thomas and Guyomard, Killian and Rabiller, Manuella and Houssais, Nina and Cormier, Alexandre and Le Monier, Pauline and Sussarellu, Rossana and Guillaume Rivi{\`e}re} } @article {9763, title = {Approaches and methods to study wildlife cancerAbstract}, journal = {Journal of Animal Ecology}, year = {2024}, month = {Mar-08-2026}, abstract = {The last few years have seen a surge of interest from field ecologists and evolutionary biologists to study neoplasia and cancer in wildlife. This contributes to the One Health Approach, which investigates health issues at the intersection of people, wild and domestic animals, together with their changing environments. Nonetheless, the emerging field of wildlife cancer is currently constrained by methodological limitations in detecting cancer using non-invasive sampling. In addition, the suspected differential susceptibility and resistance of species to cancer often make the choice of a unique model species difficult for field biologists.
Here, we provide an overview of the importance of pursuing the study of cancer in non-model organisms and we review the currently available methods to detect, measure and quantify cancer in the wild, as well as the methodological limitations to be overcome to develop novel approaches inspired by diagnostic techniques used in human medicine.
The methodology we propose here will help understand and hopefully fight this major disease by generating general knowledge about cancer, variation in its rates, tumour-suppressor mechanisms across species as well as its link to life history and physiological characters. Moreover, this is expected to provide key information about cancer in wildlife, which is a top priority due to the accelerated anthropogenic change in the past decades that might favour cancer progression in wild populations.}, issn = {0021-8790}, doi = {10.1111/1365-2656.14144}, url = {https://besjournals.onlinelibrary.wiley.com/doi/10.1111/1365-2656.14144https://besjournals.onlinelibrary.wiley.com/doi/pdf/10.1111/1365-2656.14144}, author = {Giraudeau, Mathieu and Vincze, Orsolya and Dupont, Sophie M. and Sepp, Tuul and Baines, Ciara and Lemaitre, Jean-Francois and Lemberger, Karin and Gent{\`e}s, Sophie and Boddy, Amy and Dujon, Antoine M. and Bramwell, Georgina and Harris, Valerie and Ujvari, Beata and Alix-Panabi{\`e}res, Catherine and Lair, Stephane and Sayag, David and Conde, Dalia A. and Colchero, Fernando and Harrison, Tara M. and Pavard, Samuel and Padilla-Morales, Benjamin and Chevallier, Damien and Hamede, Rodrigo and Roche, Benjamin and Malkocs, Tamas and Aktipis, Athena C. and Maley, Carlo and DeGregori, James and Le~Loc{\textquoteright}h, Guillaume and Thomas, Fr{\'e}d{\'e}ric} } @article {9917, title = {Automatic identification of the endangered Hawksbill sea turtle behavior using deep learning and cross-species transfer}, journal = {Journal of Experimental Biology}, year = {2024}, month = {Jun-11-2025}, abstract = {The accelerometer, an onboard sensor, enables remote monitoring of animal posture and movement, allowing researchers to deduce behaviors.

Despite the lack of quantitative data on these fisheries, their impact on populations\ is expected to be important because the catches can represent several tonnes per year. Consequently, fishery regulation changes have been proposed that increase the duration of the existing fisheries closure period of two weeks in March. We developed an approach to identify key periods for fisheries closure, including assessment of the proposed management scenario and several alternative protection scenarios, based on the maximization of fry abundance and on the variability of four life-history traits: (i) fry size and (ii) age at arrival in rivers, (iii) the time the juveniles spend in river before maturation and (iv) their migration behaviour. This approach is in seeking to preserve a high level of phenotypic diversity, which is predicted to promote population resilience. We conducted a multiple-criteria decision analysis to rank 4096 alternatives of fisheries closure periods, ranging from zero to 12 months, based on their propensity to maintain fry abundance and life history trait diversity. Finally, according to the type of fisheries closure period (discontinuous or continuous) and the proportion of annual abundance and variability of life-history traits preserved during the period (50\% or 75\%), we propose four different fisheries closures lasting from six to nine months.}, keywords = {amphidromy, Bichiques, Conservation, diadromy, Indian Ocean, Management, recruitment}, doi = {10.26028/cybium/2023-018}, url = {https://sfi-cybium.fr/fr/accounting-variability-life-history-traits-definition-amphidromous-goby-fry-fisheries-closure}, author = {Lagarde, Rapha{\"e}l and Valade, Pierre and Teichert, Nils} } @article {9333, title = {Aluminium-based galvanic anode impacts the photosynthesis of microphytobenthos and supports the bioaccumulation of metals released.}, journal = {Aquat Toxicol}, volume = {258}, year = {2023}, month = {2023 May}, pages = {106501}, abstract = {

Very few studies have looked at the potential biological effects of degradation products of galvanic anodes particularly on primary producers which are central to food webs in marine ecosystems. The galvanic anode cathodic protection system (GACP) is widely used to protect submerged metallic structures from corrosion. Aluminium (Al) and zinc (Zn) are the main constituents of galvanic anodes and are therefore released in the marine environment by oxidation process to form ions or oxy-hydroxides. The main objective of our study was to evaluate the effects of the metals released from an aluminium-based galvanic anode on microphytobenthos performance in term of biofilm growing through the analysis of photosynthetic parameters, the determination of chlorophyll and extracellular polymeric substances (EPS). The bioaccumulation of Al and Zn were measured in the microphytobenthic compartment collected at the surface of polyvinyl chloride (PVC) plates exposed during 13 days to seawaters enriched in different concentrations of metals released from dissolution of one anode. Determination of bioconcentration factors confirmed that the microphytobenthos has incorporated Al. A significative effect was observed on the Chl a concentration for the higher tested concentration ([Al]\ =\ 210.1\ {\textpm}\ 60.2\ {\textmu}g L\ \ ; [Zn]\ =\ 20.2\ {\textpm}\ 1.4\ {\textmu}g L\ \ ). The seawater exposed to the anode affected the MPB productivity (ETRII) with consequences on acclimatation light (Ek), absorption cross section of PSII (σ), F/F and NPQ. Regarding the EPS production, the anode degradation presented an impact on high and low molecular weight of both carbohydrates and protein fractions of microphytobenthos suggesting that EPS play an essential role in sequestering metal contaminants to maintain the integrity of the biological membranes and the functionality of the cellular organelles. The accumulation of Al released by GACP in microphytobenthos cells could lead to physiologic problems in photosynthetic organisms.

Their effectiveness is however debatable and can depend on factors such as structural complexity and construction material. Old artificial reefs (OARs) were made of concrete mold of simple geometric shapes, limiting their ability to mimic the complexity of natural reefs. Recent advancements in three-dimentional (3D)-printing technology have enabled the creation of 3D-printed artificial reefs (3DRs) with biocompatible material and complex structures that can better simulate the natural habitats. We employed underwater hyperspectral technology to estimate the performance of these reefs and compare the benthic photosynthetic signal of natural reefs (NATs) with those of ARs (OARs and 3DRs) in coastal area of the north-western Mediterranean (France and Monaco Principality). We expected differences in reflectance signals between OARs and NATs, and signals closer to NATs in 3DRs than OARs. Underwater hyperspectral technology was able to detect higher chlorophyll-a\ derived signals on NATs than OARs. Moreover, the magnitude of differences between 3DRs and NATs was smaller than that between OARs and NATs.

The species has persisted for millions of years and faced drastic environmental fluctuations thanks to its phenotypic plasticity. However, the species has recently declined to historically low levels under synergistic human pressures. Sublethal chemical contamination has been shown to alter reproductive capacity, but the impacts and required actions are not fully addressed by conservation plans. This paper proposes a modelling approach to quantify the effects of sublethal contamination by anthropogenic pollutants on the expression of life history traits and related fitness of the critically endangered European eel.\ Material and Methods: We sampled female silver eels from eight different catchments across Europe previously shown to be representative of the spectrum of environmental variability and contamination. We measured 11 fitness-related life history traits within four main categories: fecundity, adaptability and plasticity, migratory readiness, and spawning potential. We used machine learning in models to explore the phenotypic reaction (expression of these life history traits) according to geographical parameters, parasite burdens (the introduced nematode\ Anguillicoloides crassus) and anthropogenic contaminants (persistent organic pollutants (POPs) in muscular tissue and trace elements (TEs) in gonads, livers and muscles). Finally, we simulated, the effects of two management scenarios{\textemdash}contamination reduction and contamination increase{\textemdash}on the fecundity and recruitment.\ Results: Contamination in our sampling was shown to have a stronger control on life history traits than do geographic and environmental factors that are currently described in the literature. We modelled different contamination scenarios to assess the benefit of mitigation: these scenarios suggest that reducing pollutants concentrations to the lowest values that occurred in our sampling design would double the fecundity of eels compared to the current situation.\ Discussion: Remediation of contamination could represent a viable management option for increasing the resilience of eel populations, with much more effects than solely reducing fishing mortality. More broadly, our work provides an innovative way for quantitative assessment of the reaction norms of species{\textquoteright} biological traits and related fecundity to contamination by organic and inorganic pollutions thus opening new management and conservation pathways to revert the erosion of biodiversity.}, doi = {10.3390/fishes7050274}, url = {https://www.mdpi.com/2410-3888/7/5/274}, author = {Bourillon, Bastien and Feunteun, Eric and Acou, Anthony and Trancart, Thomas and Teichert, Nils and Belpaire, Claude and Dufour, Sylvie and Bustamante, Paco and Aarestrup, Kim and Walker, Alan and Righton, David} } @article {9069, title = {Arsenic and chlordecone contamination and decontamination toxicokinetics in Sargassum sp.}, journal = {Environmental Science and Pollution Research}, volume = {29}, year = {2022}, month = {Jan-01-2022}, pages = {6 - 16}, issn = {0944-1344}, doi = {10.1007/s11356-020-12127-7}, url = {https://link.springer.com/10.1007/s11356-020-12127-7}, author = {Devault, Damien A. and Massat, F{\'e}lix and Baylet, Alexandre and Dolique, Franck and Pascal Jean Lopez} } @article {8832, title = {Assessing the state of marine biodiversity in the Northeast Atlantic}, journal = {Ecological Indicators}, volume = {141}, year = {2022}, month = {Jan-08-2022}, pages = {109148}, issn = {1470160X}, doi = {10.1016/j.ecolind.2022.109148}, url = {https://linkinghub.elsevier.com/retrieve/pii/S1470160X22006203}, author = {McQuatters-Gollop, A. and Gu{\'e}rin, L. and Arroyo, N.L. and Aubert, A. and Artigas, L.F. and Bedford, J. and Corcoran, E. and Dierschke, V. and Elliott, S.A.M. and Geelhoed, S.C.V. and Gilles, A. and Gonz{\'a}lez-Irusta, J.M. and Haelters, J. and Johansen, M. and Le Loc{\textquoteright}h, F. and Lynam, C.P. and Nathalie Niquil and Meakins, B. and Mitchell, I. and Padegimas, B. and Pesch, R. and Preciado, I. and Rombouts, I. and Safi, G. and Schmitt, P. and Sch{\"u}ckel, U. and Serrano, A. and Stebbing, P. and De la Torriente, A. and Vina-Herbon, C.} } @article {8836, title = {Analysis of trophic networks: an optimisation approach}, journal = {Journal of Mathematical Biology}, volume = {83}, year = {2021}, month = {Jan-11-2021}, issn = {0303-6812}, doi = {10.1007/s00285-021-01682-3}, url = {https://link.springer.com/10.1007/s00285-021-01682-3}, author = {Caputo, Jean-Guy and Girardin, Valerie and Knippel, Arnaud and Nguyen, Minh Hieu and Nathalie Niquil and Nogues, Quentin} } @article {7654, title = {Annual phytoplankton succession results from niche-environment interactionAbstract}, journal = {Journal of Plankton Research}, volume = {43}, year = {2021}, month = {12/2020}, pages = {85{\textendash}102}, abstract = {Annual plankton succession has been investigated for many decades with hypotheses ranging from abiotic to biotic mechanisms being proposed to explain these recurrent patterns.

Geothermal streams have provided comprehensive evidence about how aquatic biodiversity changes across natural thermal gradients, but current knowledge is restricted to arctic and temperate zones. Thermal tolerances are different in tropical biological communities, resulting in high thermal sensitivity and low capacity to endure change in their thermal environments. This feature can change the response of aquatic organisms to warming, yet there is little empirical evidence to support this assumption.
In this study, we address this issue by evaluating how water temperature affects biodiversity, and the structure of primary and secondary producers of a high-elevation geothermal stream system (4,500\ m above sea level) in the Bolivian Andes. We analysed multi-taxa responses to increased water temperature using benthic macroinvertebrate families, benthic algae and cyanobacteria, fishes, and macrophytes as study organisms. Different models were run to assess the response of aquatic biota to temperature. In addition, threshold indicator taxa analysis (TITAN) was used to identify changes in macroinvertebrate taxa distributions along the thermal gradient.
We found that macroinvertebrate richness decreased at 24{\textendash}25{\textdegree}C due to the different taxon-specific responses to temperature. Threshold indicator taxa analysis identified 17 temperature thresholds for each family of macroinvertebrates. Changes in macroinvertebrate community composition were significantly associated with changes in water temperature. Similarly, changes in macrophytes were associated with temperature differences, and high macrophyte richness was found at 19{\textendash}20{\textdegree}C. Chlorophyll-a\ concentration of green algae and diatoms was higher at intermediate temperatures 20{\textendash}22{\textdegree}C, macroinvertebrates density peaked at 27{\textdegree}C, and fish body size reduced linearly with temperature.
Temperature increase in the geothermal stream resulted in a reduction of aquatic diversity and primary and secondary producers by simplifying the community structure to a few warm-adapted taxa and reduced body size. These patterns differed from those obtained in temperate/arctic geothermal streams, but are similar to other studies at high-elevation.

Using long-term datasets from six major fishing areas, from southern Chile to the Indian Ocean sector of the Southern Ocean, statistical models were developed to quantify the catch removals due to whale depredation interactions. The results indicated that these removals were large, totalling more than 6600 t of toothfish between 2009 and 2016 with an annual mean of 837 t [95\% CI 480{\textendash}1195 t], comprised of 317 t [232{\textendash}403 t] and 518 t [247{\textendash}790 t] removed by killer whales and sperm whales, respectively.

Biogeochemical cycling, particularly nitrogen (N) and phosphorus (P) in mangrove ecosystems, however, is poorly understood because of high spatial heterogeneity and temporal variability of sources, sinks, and transformation pathways. Here we show that the distribution of N and P are intimately related to vegetation distribution, tidal cycles, and seasonality. We examined the dynamics of N and P in sediments and in a tidal creek of the Can Gio Mangrove Forest, Vietnam. Our objectives were to (1) determine the spatial distribution of dissolved inorganic nitrogen and phosphorus in the mangrove forest along a Rhizophora-Avicennia-mudflat transect; and (2) identify the respective inputs and transformation pathways of N and P in the water column via 24-h time series measurements in a tidal creek. Sediment porewater had N-NH4+ and N-NO3- concentrations \< 11 μM, except in the mudflat where N-NH4+ was as high as 162 μM. This difference was likely due to N-NH4+ uptake by trees in the vegetated areas and suggests that mangrove sediments can be a zone of NH4+ production via ammonification of organic nitrogen. In all stands, P-PO43- concentrations were three-fold higher during the wet season, with a maximum of 34.4 μM. This can be explained by enhanced microbial activity during the rainy season. The phosphorus seasonal trend was also observed in the creek water but with a maximum P-PO43- value of 4.3 μM only. In the tidal creek, NNH4+ was highly variable (0 to 51 μM), with the higher values measured at low tide and related to porewater discharge from the mudflat. Our data suggest that mangroves act both as a sink of dissolved inorganic nutrients via vegetation uptake and a source of ammonium from unvegetated mudflat porewater towards the tidal creek. The dual stable isotopes approach (δ15NNO3 \& δ18ONO3) revealed that this ammonium was later nitrified within the water column. Moreover, the approach showed that some nitrate originated from the river-estuarine system during rising tides. The export of ammonium from mangrove porewater is presumably entirely consumed before exiting the tidal creek, thereby limiting the spatial extent of mangrove Outwelling. Nevertheless, our multi-isotope approach leads us to conclude that nutrients recycling via mangrove-derived organic matter mineralization may play a fundamental role in sustaining coastal food web.}, issn = {03044203}, doi = {10.1016/j.marchem.2019.103662}, url = {https://linkinghub.elsevier.com/retrieve/pii/S0304420319300489}, author = {Taillardat, Pierre and Ziegler, Alan D. and Friess, Daniel A. and Widory, David and Frank David and Ohte, Nobuhito and Nakamura, Takashi and Evaristo, Jaivime and Thanh-Nho, Nguyen and Van Vinh, Truong and Marchand, Cyril} } @article {LeGuen2019, title = {Assessing the ecological status of an estuarine ecosystem: linking biodiversity and food-web indicators}, journal = {Estuarine, Coastal and Shelf Science}, volume = {228}, year = {2019}, note = {cited By 0}, publisher = {Academic Press}, abstract = {During the last decades, the highly-anthropized Seine estuary has been impacted by modification of its habitats (building of a major extension of Le Havre harbour, i.e. Port2000) and a significant natural decrease in freshwater discharge.

The Atlantic bluefin tuna (hereafter referred to as {\textquotedblleft}bluefin tuna{\textquotedblright}), one of the world{\textquoteright}s most valuable and exploited fish species, has been declining in abundance throughout the Atlantic from the 1960s until the mid-2000s.

However, stock assessments still omit the natural, long-term variability in the species distribution. Here, we explore the century-scale fluctuations in bluefin tuna abundance and distribution to demonstrate a prevailing influence of the Atlantic Multidecadal Oscillation (AMO) to provide new insights into both the collapse of the Nordic bluefin tuna fishery circa 1963 and the recent increase in bluefin tuna abundance in the Northeast Atlantic. Our results demonstrate how climatic variability can modulate the distribution of a large migrating species to generate rapid changes in its regional abundance, and we argue that climatic variability must not be overlooked in stock management plans for effective conservation.

Tube-building sabellariid polychaetes are hermatypic organisms capable of forming vast reefs in highly turbulent marine habitats. Sabellariid worms assemble their tube by gluing together siliceous and calcareous clastic particles using a polyelectrolytic biocement. Here, we performed transcriptomic analyses to investigate the genes that are differentially expressed in the parathorax region, which contains the adhesive gland and tissues, from the rest of the body. We found a large number of candidate genes to be involved in the composition and formation of biocement in two species: Sabellaria alveolata and Phragmatopoma caudata. Our results indicate that the glue is likely to be composed by a large diversity of cement-related proteins, including Poly(S), GY-rich, H-repeat and miscellaneous categories. However, sequences divergence and differences in expression profiles between S. alveolata and P. caudata, of cement-related proteins may reflect adaptation to the type of substratum used to build their tube, and/or to their habitat (temperate vs tropical, amplitude of pH, salinity ...). Related to the L-DOPA metabolic pathways and linked with the genes that were differentially expressed in the parathorax region, we found that tyrosinase and peroxidase gene families may have undergone independent expansion in the two Sabellariidae species investigated. Our data also reinforce the importance of protein modifications in cement formation. Altogether these new genomic resources help to identify novel transcripts encoding for cement-related proteins, but also important enzymes putatively involved in the chemistry of the adhesion process, such as kinases, and may correspond to new targets to develop biomimetic approaches.

The goliath catfish Brachyplatystoma rousseauxii has crucial economical and ecological functions in the Amazon basin. Although its life history characteristics have been studied in the Amazon, there is little information in the Madeira River basin, which holds genetically distinct populations and where dams were recently built. Using fish collected in Bolivia, Brazil and Peru, this study provides a validation of growth rings deposition and details the growth patterns of B. rousseauxii in the Madeira before the dams{\textquoteright} construction. Age structure and growth parameters were determined from 497 otolith readings. The species exhibits two growth rings per year and sampled fish were between 0 and 16 years old. In the Brazilian portion of the basin, mainly young individuals below 5 years old were found, whereas older fish (\> 5 years) were caught only in the Bolivian and Peruvian stretches, indicating that after migrating upstream to reproduce, adults remain in the headwaters of the Madeira River. Comparing with previous publications, B. rousseauxii had a slower growth and 20 cm lower maximum standard length in the Madeira River than in the Amazon River. This study provides a baseline for future evaluation of changes in population dynamics of the species following dams closure.

Algal blooms occurrence is increasing around the globe. However, algal blooms are uncommon in dominantly oligotrophic high-altitude lakes. Lake Titicaca, the largest freshwater lake in South America, located at 3809 m above the sea level, experienced its first recorded algal bloom covering a large fraction of its southern shallow basin in March{\textendash}April 2015. The dominant algae involved in the bloom was Carteria sp. Water geochemistry changed during the bloom with a simultaneous alkalinization in heterotrophic parts of the lake and acidification in eutrophic shallow areas. A decrease in oxygen saturation (from 105 to 51\%), and a dramatic increase in hydrogen sulfide (H2S) concentrations (from \<0.02 to up to 155 {\textmu}g.L-1) resulted in the massive death of pelagic organisms. Such changes were brought by the exacerbated activity of sulfate-reducing bacteria (SRB) in this sulfate-rich lake. Although levels in total mercury remained stable during the event, MMHg \% rose, highlighting higher conservation of produced MMHg in the water. Such an increase on MMHg \% has the potential to produce exponential changes on MMHg concentrations at the end food web due to the biomagnification process. Our physicochemical and climatological data suggest that unusually intense rain events released large amounts of nutrients from the watershed and triggered the bloom. The observed bloom offers a hint for possible scenarios for the lake if pollution and climate change continue to follow the same trend. Such a scenario may have significant impacts on the most valuable fish source in the Andean region and the largest freshwater Lake in South America. Furthermore, the event illustrates a possible fate of high altitude environments subjected to eutrophication.

Phytoplankton primary production varies considerably with environmental parameters especially in dynamic ecosystems like estuaries. The aimof this study was to investigate short-term primary production along the salinity gradient of a temperate estuary over the course of 1 year. The combination of carbon incorporation and fluorescence methods enabled primary production estimation at short spatial and temporal scales. The electron requirement for carbon fixation was investigated in relation with physical-chemical parameters to accurately estimate primary production at high frequency. These results combined with the variability of the photic layer allowed the annual estimation of primary production along the estuary. Phytoplankton dynamics was closely related to salinity and turbidity gradients, which strongly influenced cells physiology and photoacclimatation. The number of electrons required to fix 1 mol of carbon (C) was ranged between 1.6 and 25 mol electron mol C-1 with a mean annual value of 8 {\textpm} 5 mol electron mol C-1. This optimum value suggests that in nutrient replete conditions like estuaries, alternative electron flows are low, while electrons transfer from photosystem II to carbon fixation is highly efficient. A statistical model was used to improve the estimation of primary production from electron transport rate as a function of significant environmental parameters. Based on this model, daily carbon production in the Seine estuary (France) was estimated by considering light and photic zone variability. A mean annual daily primary production of 0.12 {\textpm} 0.18 g C m-2 day-1 with a maximum of 1.18 g C m-2 day-1 in summer was estimated which lead to an annual mean of 64.75 g C m-2 year-1. This approach should be applied more frequently in dynamic ecosystems such as estuaries or coastal waters to accurately estimate primary production in those valuable ecosystems.

In most cities, streets are designed for collecting and transporting dirt, litter, debris, storm water and other wastes as a municipal sanitation system. Microbial mats can develop on street surfaces and form microbial communities that have never been described. Here, we performed the first molecular inventory of the street gutter-associated eukaryotes across the entire French capital of Paris and the non-potable waters sources. We found that the 5782 OTUs (operational taxonomic units) present in the street gutters which are dominated by diatoms (photoautotrophs), fungi (heterotrophs), Alveolata and Rhizaria, includes parasites, consumers of phototrophs and epibionts that may regulate the dynamics of gutter mat microbial communities. Network analyses demonstrated that street microbiome present many species restricted to gutters, and an overlapping composition between the water sources used for street cleaning (for example, intra-urban aquatic networks and the associated rivers) and the gutters. We propose that street gutters, which can cover a significant surface area of cities worldwide, potentially have important ecological roles in the remediation of pollutants or downstream wastewater treatments, might also be a niche for growth and dissemination of putative parasite and pathogens.The ISME Journal advance online publication, 13 October 2017; doi:10.1038/ismej.2017.166.

Over the last two decades there has been an exponential increase in the use of correlative species distribution models (SDMs) to address a variety of topics in ecology, biogeography, evolution, and conservation biology. Conversely, the use of these statistical methods to study the potential distribution of subterranean organisms has lagged behind, relative to their above-ground (epigean) counterparts. The reason for this is possibly related to a number of peculiarities of subterranean systems, which pose important limits, but also opportunities, for these correlative models. The aim of this forum is to explore the caveats that need to be made when generalizing these statistical techniques to caves and other subterranean habitats. We focus on the typical bias in spatial datasets of cave-dwelling species, and provide advice for selecting the model calibration area. In parallel, we discuss the potential use of different large scale surface variables to represent the subterranean condition. A more widespread adoption of these statistical techniques in subterranean biology is highly attractive and has great potential in broadening our knowledge on a variety of ecological topics, especially in the fields of climate change and biodiversity conservation. Their use would especially benefit the study of the biogeographic patterns of subterranean fauna and the impact of past and future climate change on subterranean ecosystems.

The early brain development, at the time of gonadal differentiation was investigated using a protandrous teleost, black porgy. This natural model of monosex juvenile fish avoids the potential complexity of sexual dimorphism. Brain neurogenesis was evaluated by histological analyses of the diencephalon, at the time of testicular differentiation (in fish between 90 and 150 days after hatching). Increases in the number of both Nissl-stained total brain cells, and Pcna-immunostained proliferative brain cells were observed in specific area of the diencephalon, such as ventromedialis thalami and posterior preoptic area, revealing brain cell proliferation. qPCR analyses showed significantly higher expression of the radial glial cell marker blbp and neuron marker bdnf. Strong immunohistochemical staining of Blbp and extended cellular projections were observed. A peak expression of aromatase (cyp19a1b), as well as an increase in estradiol (E2 ) content were also detected in the early brain. These data demonstrate that during gonadal differentiation, the early brain exhibits increased E2 synthesis, cell proliferation, and neurogenesis. To investigate the role of E2 in early brain, undifferentiated fish were treated with E2 or aromatase inhibitor (AI). E2 treatment upregulated brain cyp19a1b and blbp expression, and enhanced brain cell proliferation. Conversely, AI reduced brain cell proliferation. Castration experiment did not influence the brain gene expression patterns and the brain cell number. Our data clearly support E2 biosynthesis in the early brain, and that brain E2 induces neurogenesis. These peak activity patterns in the early brain occur at the time of gonad differentiation but are independent of the gonads.

Periphyton relevance for methylmercury (MeHg) production and accumulation are now well known in aquatic ecosystems. Sulfate-reducing bacteria and other microbial groups were identified as the main MeHg producers, but the effect of periphyton algae on the accumulation and transfer of MeHg to the food web remains little studied. Here we investigated the role of specific groups of algae on MeHg accumulation in the periphyton of Schoenoplectus californicus ssp. (Totora) and Myriophyllum sp. in Uru Uru, a tropical high-altitude Bolivian lake with substantial fishing and mining activities accruing around it. MeHg concentrations were most strongly related to the cell abundance of the Chlorophyte genus Oedogonium (r 2\ =\ 0.783, p\ =\ 0.0126) and to no other specific genus despite the presence of other 34 genera identified. MeHg was also related to total chlorophyll-a (total algae) (r 2\ =\ 0.675, p\ =\ 0.0459), but relations were more significant with chlorophyte cell numbers, chlorophyll-b (chlorophytes), and chlorophyll-c (diatoms and dinoflagellates) (r 2\ =\ 0.72, p\ =\ 0.028, r 2\ =\ 0.744, p\ =\ 0.0214, and r 2\ =\ 0.766, p\ =\ 0.0161 respectively).

Little is known about the ecological and physiological processes governing depth distribution limits in species. Temperature and hydrostatic pressure are considered to be two dominant factors. Research has shown that some marine ectotherms are shifting their bathymetric distributions in response to rapid anthropogenic ocean surface warming. Shallow-water species unable to undergo latitudinal range shifts may depend on bathymetric range shifts to seek refuge from warming surface waters. As a first step in constraining the molecular basis of pressure tolerance in shallow water crustaceans, we examined differential gene expression in response to acute pressure and temperature exposures in juveniles of the shallow-water shrimp Palaemonetes varians. Significant increases in the transcription of genes coding for an NMDA receptor-regulated protein, an ADP ribosylation factor, β-actin, two heat shock protein 70 kDa isoforms (HSP70), and glyceraldehyde-3-phosphate dehydrogenase (GAPDH) were found in response to elevated pressure. NMDA receptors have been implicated in pathways of excitotoxic damage to neurons and the onset of high pressure neurological syndrome (HPNS) in mammals. These data indicate that the sub-lethal effects of acute barotrauma are associated with transcriptional disturbances within the nervous tissue of crustaceans, and cellular macromolecular damage. Such transcriptional changes lead to the onset of symptoms similar to that described as HPNS in mammals, and may act as a limit to shallow water organisms{\textquoteright} prolonged survival at depth.

BACKGROUND: Originating from Northeast Asia, the Pacific oyster Crassostrea gigas has been introduced into a large number of countries for aquaculture purpose. Following introduction, the Pacific oyster has turned into an invasive species in an increasing number of coastal areas, notably recently in Northern Europe.

METHODS: To explore potential adaptation of reproductive traits in populations with different histories, we set up a common garden experiment based on the comparison of progenies from two populations of Pacific oyster sampled in France and Denmark and their hybrids. Sex ratio, condition index and microarray gene expression in gonads, were analyzed in each progeny (n = 60).

RESULTS: A female-biased sex-ratio and a higher condition index were observed in the Danish progeny, possibly reflecting an evolutionary reproductive strategy to increase the potential success of natural recruitment in recently settled population. Using multifarious statistical approaches and accounting for sex differences we identified several transcripts differentially expressed between the Danish and French progenies, for which additive genetic basis is suspected (showing intermediate expression levels in hybrids, and therefore additivity). Candidate transcripts included mRNA coding for sperm quality and insulin metabolism, known to be implicated in coordinated control and success of reproduction.

CONCLUSIONS: Observed differences suggest that adaptation of invasive populations might have occurred during expansion acting on reproductive traits, and in particular on a female-biased sex-ratio, gamete quality and fertility.

{\textcopyright} 2015 Elsevier Ltd. Shorebird populations are declining worldwide due to the combined effect of climate change and anthropogenic forcing, the ongoing coastal urbanisation amplifying the alteration of their habitat in both rate and magnitude. By focusing on a highly anthropogenically-influenced region in Northern France, we studied the impact of a seawall construction on wintering shorebird populations through potential alterations in the abundance and availability of their food resources. We concurrently investigated changes in the spatial distribution of muddy-sand beach macrobenthic communities between two periods of contrasting anthropogenic impacts and examined year-to-year trends of wintering shorebirds. Our study reveals that the seawall construction led to a major spatial reorganisation of the macrobenthic communities with a drastic reduction of the muddy-sand community. However, no relation between macrobenthic changes and shorebird abundances was detected. Fluctuations in shorebird abundances appeared to be congruent with flyway population trends. This result suggests that the response of shorebirds to human-induced perturbations is much more complex than expected. While an assessment of potential disturbances induced by coastal engineering constructions is needed, the pathways by which alterations could propagate through an ecosystem are not linear and as such difficult to determine. Ecosystems appear as complex adaptive systems in which macroscopic dynamics emerge from non-linear interactions at entangled smaller/larger scales. Our results confirm that an in-depth knowledge of the local, regional and global factors that influence trends of shorebirds and their habitat use is essential for accurate and effective management and conservation strategies.

There is increasing evidence that pollutants may cause diseases via epigenetic modifications. Epigenetic mechanisms such as DNA methylation participate in the regulation of gene transcription. Surprisingly, epigenetics research is still limited in ecotoxicology. In this study, we investigated whether chronic exposure to contaminants experienced by wild female fish (Anguilla anguilla) throughout their juvenile phase can affect the DNA methylation status of their oocytes during gonad maturation. Thus, fish were sampled in two locations presenting a low or a high contamination level. Then, fish were transferred to the laboratory and artificially matured. Before hormonal treatment, the DNA methylation levels of the genes encoding for the aromatase and the receptor of the follicle stimulating hormone were higher in contaminated fish than in fish from the clean site. For the hormone receptor, this hypermethylation was positively correlated with the contamination level of fish and was associated with a decrease in its transcription level. In addition, whereas gonad growth was associated with an increase in DNA methylation in fish from the clean site, no changes were observed in contaminated fish in response to hormonal treatment. Finally, a higher gonad growth was observed in fish from the reference site in comparison to contaminated fish.

Currently, the hazard posed by pharmaceutical residues is a major concern of ecotoxicology. Most of the antidepressants belong to a family named the Cationic Amphipathic Drugs known to have specific interactions with cell membranes. The present study assessed the impact of eight antidepressants belonging to selective serotonin reuptake inhibitors or serotonin norepinephrine reuptake inhibitors by the combination of multi-approaches (in vivo, in vitro, in silico) and gives some insights on the mode of action for these molecules. Antidepressants were from the most to the least toxic compound for Daphnia magna: Sertraline (EC50=1.15 mg L(-1))\>Clomipramine (2.74 mg L(-1))\>Amitriptyline (4.82 mg L(-1))\>Fluoxetine (5.91 mg L(-1))\>Paroxetine (6.24 mg L(-1))\>Mianserine (7.81 mg L(-1))\>Citalopram (30.14 mg L(-1)) and Venlafaxine (141.28 mg L(-1)). These acute toxicities were found correlated to Log Kow coefficients (R=0.93, p\<0.001) and to cytotoxicity assessed on abalone hemocytes through the neutral red uptake assay (R=0.96, p\<0.001). If narcosis as mode of action is typically expected during acute ecotoxicity bioassays, we showed by molecular modeling that particular interactions can exist between antidepressants and phosphatidylcholine, a major component of cell membranes, leading to a more specific mode of action corresponding to a potential acidic hydrolysis of ester functions.

Even if amphidromous fish species contribute most to the diversity of fish communities in the tropical insular
rivers, their biological cycle remain poorly known. For the first time, the otolith elemental composition and microstructure
of two ancestral gobioids, Rhyacichthys guilberti and Protogobius attiti, were investigated to describe their biological
cycle and pelagic larval duration (PLD). The otolith analysis using a femtosecond laser ablation coupled to an inductively
coupled plasma{\textendash}mass spectrometer (fs-LA-ICP-MS) revealed an amphidromous life history for R. guilberti and it
suggested a progressive habitat shift from a marine habitat to a freshwater environment for P. attiti. For the first time, an
endemic species, P. attiti, showed longer and more variable PLD (55.213.5 days) than did a widespread one
(R. guilberti: ,30 days). These results need to be confirmed by analysing more samples but suggest that factors other
than the PLD control endemism and dispersal processes. In association with this first description of the biological cycle for
both species, such an approach is a prerequisite for the management and conservation of both patrimonial species.

Pharmaceutical compounds like antidepressants found in surface waters raise concerns due to their potential toxicity on non-target aquatic organisms. This study aimed at investigating the in vitro cytotoxicity and immunomodulatory properties of four common antidepressants, namely Amitriptyline, Clomipramine, Citalopram and Paroxetine, on primary cultures of abalone hemocytes (Haliotis tuberculata), after 48 h-exposure. Effects on immunocompetence (phagocytosis, levels of reactive oxygen species, esterase activity and lysosomal membrane destabilization) were assessed. Results obtained by MTT assays revealed that acute toxicity is unlikely to occur in the environment since the LC50s of the four antidepressants are at the mg/L level. The different immunological endpoints displayed a biphasic response, with an increase at the lowest concentration (i.e. 1 μg/L) followed by a decrease at higher concentrations. Overall, Amitriptyline and Clomipramine, the two tricyclic antidepressants, had higher immunomodulatory capacities than the two selective serotonin reuptake inhibitors Citalopram and Paroxetine. Amitriptyline was the most potent and Citalopram the least potent drug in altering immune function in H. tuberculata.

Ecosystem effects of climate change have been detected in all components of the Earth System. In the marine biosphere, climate-change responses have caused large and well-documented biogeographical and phenological shifts, which have in turn altered local dominance hierarchies, and also the structure, diversity and functional linkages within regional marine ecosystems. There is an urgent need to improve both our knowledge of the global-scale effects of climate change on marine biodiversity and our capacity to project future impacts. But extrapolation of previously estimated changes to additional places and to future conditions is complicated by non-linear responses to environmental variables, and also by complexities of multivariate interaction that can lead to tipping-points. In this paper, we show how observations from widely-spaced locations can be combined to characterise the ecological niche of a species, and how the concept of the niche can be used to understand and project how climate-induced changes in temperatures will alter marine zooplankton both locally and globally. As an example to illustrate our view, we apply this framework to the relatively well-known copepod Calanus finmarchicus. Our results suggest that climate change will strongly affect the local abundance of this species in the North Atlantic Ocean by the end of this century. Predicted changes are large (e.g. increase by ??6-10-fold of the temporal changes in the abundance of C. finmarchicus) and vary as a function of the magnitude of warming and the local sign and steepness of the thermal niche. Substantial rates of change hold even under optimistic climatic scenarii. After reviewing the main limitations of the niche concept in bioclimatological research, we argue that the application of this concept in ecology and bioclimatology might nevertheless represent the best tool currently available to scientists to discern and anticipate the effect of global climate change on species and ecosystems. The framework we proposed forces us however to think globally and to develop a worldwide coordinated macroecological approach, that includes global monitoring, new mathematical tools of detection and new types of modeling. ?? 2012 Elsevier Ltd.
