	abstract = {The study is the first attempt to (i) model spring food webs in three SW Mediterranean ecosystems which are under different anthropogenic pressures and (ii) to project the consequence of this stress on their function. Linear inverse models were built using the Monte Carlo method coupled with Markov Chains to characterize the food-web status of the Lagoon, the Channel (inshore waters under high eutrophication and chemical contamination) and the Bay of Bizerte (offshore waters under less anthropogenic pressure). Ecological network analysis was used for the description of structural and functional properties of each food web and for inter-ecosystem comparisons. Our results showed that more carbon was produced by phytoplankton in the inshore waters (966{\textendash}1234 mg C m-2 d-1) compared to the Bay (727 mg C m-2 d-1). The total ecosystem carbon inputs into the three food webs was supported by high primary production, which was mainly due to \&gt;10 {\textmu}m algae. However, the three carbon pathways were characterized by low detritivory and a high herbivory which was mainly assigned to protozooplankton. This latter was efficient in channelling biogenic carbon. In the Lagoon and the Channel, foods webs acted almost as a multivorous structure with a tendency towards herbivorous one, whereas in the Bay the herbivorous pathway was more dominant. Ecological indices revealed that the Lagoon and the Channel food webs/systems had high total system throughput and thus were more active than the Bay. The Bay food web, which had a high relative ascendency value, was more organized and specialized. This inter{\textendash}ecosystem difference could be due to the varying levels of anthropogenic impact among sites. Indeed, the low value of Finn{\textquoteright}s cycling index indicated that the three systems are disturbed, but the Lagoon and the Channel, with low average path lengths, appeared to be more stressed, as both sites have undergone higher chemical pollution and nutrient loading. This study shows that ecosystem models combined with ecological indices provide a powerful approach to detect change in environmental status and anthropogenic impacts. {\textcopyright} 2018},

	abstract = {Modern approaches to Ecosystem-Based Management and sustainable use of marine resources must account for the myriad of pressures (interspecies, human and environmental) affecting marine ecosystems. The network of feeding interactions between co-existing species and populations (food webs) are an important aspect of all marine ecosystems and biodiversity. Here we describe and discuss a process to evaluate the selection of operational food-web indicators for use in evaluating marine ecosystem status. This process brought together experts in food-web ecology, marine ecology, and resource management, to identify available indicators that can be used to inform marine management. Standard evaluation criteria (availability and quality of data, conceptual basis, communicability, relevancy to management) were implemented to identify practical food-web indicators ready for operational use and indicators that hold promise for future use in policy and management. The major attributes of the final suite of operational food-web indicators were structure and functioning. Indicators that represent resilience of the marine ecosystem were less developed. Over 60 potential food-web indicators were evaluated and the final selection of operational food-web indicators includes: the primary production required to sustain a fishery, the productivity of seabirds (or charismatic megafauna), zooplankton indicators, primary productivity, integrated trophic indicators, and the biomass of trophic guilds. More efforts should be made to develop thresholds-based reference points for achieving Good Environmental Status. There is also a need for international collaborations to develop indicators that will facilitate management in marine ecosystems used by multiple countries. {\textcopyright} 2017 International Council for the Exploration of the Sea.

	abstract = {The dynamics of the phytoplankton assemblage, the physical, chemical and biological
parameters, and primary productivity and production were monitored in the central English
Channel along a transect between Ouistreham and Portsmouth from January to December 2010.
The spatial patterns of the phytoplankton assemblage were controlled by the hydrological characteristics
of the water masses, and the annual structure of the phytoplankton assemblage was characteristic
of the central English Channel and was controlled by seasonality. The spring bloom was
dominated by a single species, Chaetoceros socialis, and associated with low microphytoplankton
evenness and Shannon-Wiener indices, whereas the evenness index was high from late spring to
winter and associated with the proliferation of pico- and nanophytoplankton cells. We identified 2
species responsible for harmful algal blooms, Phaeocystis globosa, which dominated the community
in the northern part of the Seine Bay in May, and Lepidodinium chlorophorum, which dominated
the community near the French coast in September. We examined the relationship between
microphytoplankton diversity and maximum primary production and productivity. We found a
negative parabolic relationship between the diversity indices (evenness and Shannon-Wiener)
and maximum primary production, and a positive parabolic relationship between the number of
taxa (richness) and maximum primary production. However, we found no relationship between
maximum productivity and the evenness or richness indices. High levels of productivity were
measured during the increasing abundance of pico and nanophytoplankton cells, highlighting the
importance of taking the dominant functional group into account, rather than the degree of diversity,
when explaining the level of productivity.},
