Provedor de dados: 5
Autores: Jac, Cyrielle; Desroy, Nicolas; Certain, Gregoire; Foveau, Aurelie; Labrune, Céline; Vaz, Sandrine.
By relating observed changes to the pressures suffered, the Marine Strategy Framework Directive intends to better control the factors of environmental degradation and to manage their consequences in European waters. Several descriptors are defined within the framework of the MFSD and in particular descriptor 1 relating to the biological diversity of the seabed and descriptor 6 relating to the seabed integrity (i.e. the quality of their structures and functions). For each descriptor, indicators and threshold values must be defined and a novel conceptual approach to define and detect seabed integrity thresholds is proposed here. Bottom trawling being the main source of shelf continental disturbance, it is important to evaluate its impact on benthic habitat....

This is the 36th annual surveillance report concerning the nuclear power plant of Gravelines. Its very high power level results from six plant units located on the shore and is characterised by a cooling system with a coastal surface input and output. The production of electricity began in 1980 and reached maximum in 1986. Surveys concern monitoring of pelagic system (hydrology, microbiology, phytoplankton, and zooplankton), fish populations (larvae and eggs of Sole and Sprat) or crustaceans (shrimps), and benthic macrofauna (intertidal and subtidal). This survey deals with spatial and temporal approaches (i) study of the direct impact by comparison of the input and output seawater stations, (ii) study of medium and long term evolution of the area by...

Detecting adverse effect on seabed integrity. Part 1: Generic sensitivity indices to measure the effect of trawling on benthic mega-epifauna
Provedor de dados: 5
Autores: Jac, Cyrielle; Desroy, Nicolas; Certain, Gregoire; Foveau, Aurelie; Labrune, Céline; Vaz, Sandrine.
The benthic fauna of European continental shelves is a severely impacted community, mostly due to intense bottom trawling activity. Trawling effect may be dependent on the spatial and temporal distribution of abrasion, the habitat type including natural perturbation intensity and the fishing gear used. Nonetheless, there is an urgent need to identify or develop indices likely to measure the effect of trawling. For this purpose benthic fauna by-catch monitored in scientific trawl surveys carried out in all European waters in the frame of the Common Fishery Policy Data Collection Multiannual Program may be used. Benthic invertebrates data used in this study were collected during scientific bottom trawl surveys covering the English Channel, the North Sea and...

Interregional comparison of benthic ecosystem functioning: Community bioturbation potential in four regions along the NE Atlantic shelf
Provedor de dados: 5
Autores: Gogina, Mayya; Zettler, Michael L.; Vanaverbeke, Jan; Dannheim, Jennifer; Van Hoey, Gert; Desroy, Nicolas; Wrede, Alexa; Reiss, Henning; Degraer, Steven; Van Lancker, Vera; Foveau, Aurelie; Braeckman, Ulrike; Fiorentino, Dario; Holstein, Jan; Birchenough, Silvana N.r.
Bioturbation is one of the key mediators of biogeochemical processes in benthic habitats that can have a high contribution to seafloor functioning and benthic pelagic coupling in coastal waters. Previous studies on bioturbation were limited to point locations and extrapolations in single regions, but have not accounted for regional differences under changing environmental conditions, though there are indications that species contributions will differ across regions or with biotic and abiotic context. To capture those differences and assess global patterns and commonalities, multi-regional analyses are imperative. Here for the first time, bioturbation potential (BPc), a functional indicator of benthic community bioturbation, was estimated based on...

Habitats et communautés benthiques du bassin oriental de la Manche : état des lieux au début du XXIe siècle
Provedor de dados: 5
Autores: Foveau, Aurelie.
This study is devoted in providing an updated knowledge on the macrobenthic community structure and biodiversity in the eastern English Channel in the early 2000s. Results obtained were compared with results obtained by L. Cabioch and colleagues for the period of 1971-1976. The distribution of macrobenthic communities is highly governed by the sedimentary cover. The Folk classification was used for sedimentology and mapping of bottom type characterization for the two study periods. A relative stability of the sedimentary cover was observed wherein 69% of the study area showed slight or no change in sedimentary cover. This is mainly due to the hydrodynamics in the area which is the dominant structuring factor in the eastern English Channel. Variations were...

Distribution patterns in the benthic diversity of the eastern English Channel
Provedor de dados: 5
Autores: Foveau, Aurelie; Desroy, Nicolas; Dauvin, Jean-claude; Dewarumez, Jean-marie.
Understanding the distribution of specific diversity is currently an important focus in marine research, and the role of marine biodiversity has been fully recognised as essential for the proper functioning of the biosphere. The objective of this study was to explain the distribution of macrobenthic taxonomic richness (vagile epifauna, endofauna and sessile epifauna) in the eastern part of the English Channel using both classical methods and applying the mid-domain effect (MDE) model. High diversity was encountered in the eastern English Channel (875 taxa), with high-diversity areas often comprising gravelly or pebbly sediments. Sessile epifauna represented 25% of this inventory, revealing the importance of this group. Our results underline the existence...

Morphospecies and taxonomic sufficiency of benthic megafauna in scientific bottom trawl surveys
Provedor de dados: 5
Autores: Brind'Amour, Anik; Laffargue, Pascal; Morin, Jocelyne; Vaz, Sandrine; Foveau, Aurelie; Le Bris, Herve.
Scientific fisheries surveys routinely identify a large diversity of commercial and non-commercial benthic megainvertebrates that could provide useful information for Marine Strategy Framework Directive (MSFD) descriptors. Species is obviously the basic taxonomic level to which most ecological studies and theories refer. Identification at this level of organization is indeed always preferred over any other taxonomic level. Nevertheless, aggregation of species to higher taxonomic levels may be unavoidable sometimes, since errors of identification are known or suspected to occur in many surveys. Using analyses of taxonomic sufficiency (identification of organisms at various taxonomic resolutions) and groups of morphospecies (taxa identified easily by...

Range extension of the tanaidid Zeuxo holdichi (Bamber, 1990) along the northern coasts of France?
Provedor de dados: 5
Autores: Foveau, Aurelie; Pezy, Jean-philippe; Bauxi, Noemie; Baffreau, Alexandrine; Bachelet, Quentin; Chouquet, Bastien; Dancie, Chloe; Ruellet, Thierry; Dauvin, Jean-claude.
The tanaidacean crustacean, Zeuxo holdichi was first described from Arcachon Bay, France, by Bamber in 1990. Since then, this species has been recorded several times in Europe, from Iberian Peninsula to Germany. In this present study, we report new records of this species along the northern coasts of France bordering the English Channel. It is hypothesized that Z. holdichi is being spread because of aquaculture activities.

The eastern English Channel, which connects the Atlantic Ocean to the North Sea through the Dover Strait, is an area where numerous and often conflicting human activities take place. A cross-border multidisciplinary project called CHARM was initiated to provide knowledge and tools for planners and decision-makers to durably manage the shared marine living resources. One such tool was an atlas of fish spatial distributions and modelled habitats, which was used here to investigate ontogenic and seasonal shifts in fish spatial distribution and habitat through a case-study, the dab Limanda limanda. Survey data for several life-history stages (eggs, larvae, coastal nurseries, &lt; and &gt; 1 year old) and seasons were used to map spatial patterns (using...

Modelling larval dispersal of the king scallop (Pecten maximus) in the English Channel: examples from the bay of Saint-Brieuc and the bay of Seine
Provedor de dados: 5
Autores: Nicolle, Amandine; Dumas, Franck; Foveau, Aurelie; Foucher, Eric; Thiebaut, Eric.
The king scallop (Pecten maximus) is one of the most important benthic species of the English Channel as it constitutes the first fishery in terms of landings in this area. To support strategies of spatial fishery management, we develop a high-resolution biophysical model to study scallop dispersal in two bays along the French coasts of the English Channel (i.e. the bay of Saint-Brieuc and the bay of Seine) and to quantify the relative roles of local hydrodynamic processes, temperature-dependent planktonic larval duration (PLD) and active swimming behaviour (SB). The two bays are chosen for three reasons: (1) the distribution of the scallop stocks in these areas is well known from annual scallop stock surveys, (2) these two bays harbour important fisheries...

Modelling larval dispersal of     Pecten maximus     in the English Channel: a tool for the spatial management of the stocks
Provedor de dados: 5
Autores: Nicolle, Amandine; Moitie, Roderic; Ogor, Julien; Dumas, Franck; Foveau, Aurelie; Foucher, Eric; Thiebaut, Eric.
The great scallop Pecten maximus supports one of the most important and valuable commercial fisheries around the British Isles and in the northwest of France, but the resource is mainly managed at the scale of each local fishing ground through a combination of European, national and local measures. To analyse the larval dispersal pathways and connectivity patterns among fishing grounds of the great scallop in the Celtic Sea and the English Channel, a particle tracking model was developed. The model combined a 3D physical circulation model that simulated currents and temperature fields and a scallop larval submodel that took into account a temperature-dependent planktonic larval duration and an active vertical swimming behaviour. Due to the lack of stock...

Autores: Metcalfe, Kristian; Delavenne, Juliette; Garcia, Clement; Foveau, Aurelie; Dauvin, Jean-claude; Coggan, Roger; Vaz, Sandrine; Harrop, Stuart R.; Smith, Robert J.
Aim : The speciesarea relationship (SAR) is increasingly being used to set conservation targets for habitat types when designing protected area networks. This approach is transparent and scientifically defensible, but there has been little research on how it is affected by data quality and quantity. Location : English Channel.  Methods :  We used a macrobenthic dataset containing 1314 sampling points and assigned each point to its associated habitat type. We then used the SAR-based approach and tested whether this was influenced by changes in (i) the number of sampling points used to generate estimates of total species richness for each habitat type; (ii) the nonparametric estimator used to calculate species richness; and (iii) the level of habitat...

Process-driven and biological characterisation and mapping of seabed habitats sensitive to trawling
Provedor de dados: 5
Autores: Foveau, Aurelie; Vaz, Sandrine; Desroy, Nicolas; Kostylev, Vladimir E.
The increase of anthropogenic pressures on the marine environment together with the necessity of a sustainable management of marine living resources have underlined the need to map and model coastal environments, particularly for the purposes of spatial planning and for the implementation of integrated ecosystem-based management approach. The present study compares outputs of a process-driven benthic habitat sensitivity (PDS) model to the structure, composition and distribution of benthic invertebrates in the Eastern English Channel and southern part of the North Sea. Trawl disturbance indicators (TDI) computed from species biological traits and benthic community composition were produced from samples collected with a bottom trawl. The TDI was found to be...

Surprisingly diversified macrofauna in mobile gravels and pebbles from high-energy hydrodynamic environment of the ‘Raz Blanchard’ (English Channel)
Provedor de dados: 5
Autores: Foveau, Aurelie; Dauvin, Jean-claude.
Our study concerns the sampling of patches of mobile gravel and pebbles at 14 stations (25 to 66 m water depth) in an area of hard bottom located in the ‘Raz Blanchard’ (between Cap de La Hague in France and Alderney in the Channel Islands, UK). The samples collected from these benthic habitats with scattered fauna were sieved on 1-mm mesh and subjected to meticulous sorting, revealing the presence of a highly diversified mobile fauna. The epifauna and vagile macrofauna (&gt;1 mm) account for 140 taxa (120 species, 17 genera and three other levels of identification). Amphipods and polychaetes dominate the taxonomic richness, while crustaceans represent 75% of the fauna. Among these taxa, two species are new for the English Channel marine fauna. Biological...

Autores: Le Goff, Clement; Lavaud, Romain; Cugier, Philippe; Jean, Fred; Flye-sainte-marie, Jonathan; Foucher, Eric; Desroy, Nicolas; Fifas, Spyros; Foveau, Aurelie.
In this paper we used a modelling approach integrating both physical and biological constraints to understand the biogeographical distribution of the great scallop Pecten maximus in the English Channel during its whole life cycle. A 3D bio-hydrodynamical model (ECO-MARS3D) providing environmental conditions was coupled to (i) a population dynamics model and (ii) an individual ecophysiological model (Dynamic Energy Budget model). We performed the coupling sequentially, which underlined the respective role of biological and physical factors in defining P. maximus distribution in the English Channel. Results show that larval dispersion by hydrodynamics explains most of the scallop distribution and enlighten the main known hotspots for the population,...
