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, < and > 1 year old) and seasons were used to map spatial patterns (using...

Atlas des Habitats des Ressources Marines de la Manche Orientale - CHARM II ArchiMer
Carpentier, Andre; Coppin, Franck; Curet, Lucie; Dauvin, Jean-claude; Delavenne, Juliette; Dewarumez, Jean-marie; Dupuis, Ludovic; Foveau, Aurélie; Garcia, Clément; Gardel, Laure; Harrop, Stuart; Just, Roger; Koubbi, Philippe; Lauria, Valentina; Martin, Corinne; Meaden, Geoff; Morin, Jocelyne; Ota, Yoshi; Rostiaux, Emilie; Smith, Bob; Spilmont, Nicolas; Vaz, Sandrine; Villanueva, Ching-maria; Verin, Yves; Walton, Joanne; Warembourg, Caroline.
Readers of our first CHARM I atlas will know that almost everything contained within the atlas was original work resulting from two years of intensive study of the Dover Strait by a dedicated and inter- disciplinary team working from bases on either side of the Channel. The present atlas has carried on this eminent precedent, though this time covering the whole of the eastern English Channel (figure 1) and widening considerably the thematic scope. We believe that readers of this current atlas will be impressed by both the breadth and depth of the information provided, and that therefore this content should be available for use in both a wide variety of fields and at various levels of interest (researchers, industries, statutory organisations, the wider...

Conservation of marine habitats under multiple human uses. Methods, objectives and constraints to optimize a Marine Protected Areas network in the eastern English Channel ArchiMer
Delavenne, Juliette.
The eastern English Channel is a significant economic area that supports a number of human-based activities, such as tourism and recreational activities, international ports and shipping, and the extraction of both living and mineral resources. In addition, the region supports a number of important marine biological features and large habitat diversity. Marine Protected Areas (MPAs) are increasingly used as a management tool to foster a sustainable exploitation of marine resources in an ecosystem based management framework. All European countries have a legal obligation to develop MPA networks in their national waters. However, there has to date been only limited attempts to coordinate the design and positioning of such networks at an international level...

Deep-sea benthic communities in the largest oceanic desert are structured by the presence of polymetallic crust ArchiMer
Delavenne, Juliette; Keszler, Louise; Castelin, Magalie; Lozouet, Pierre; Maestrati, Philippe; Samadi, Sarah.
Based on the specimens collected during three deep-sea cruises, and deposited at the Muséum National d’Histoire Naturelle (MNHN) in Paris, we analysed the diversity of benthic communities within the EEZ of French Polynesia. The literature and the MNHN database allowed us to inventory 471 species of invertebrates, among which 169 were newly described. We mainly found data for Mollusca, Crustacea, Brachiopoda and Crinoidea. We also found samples from other taxa, which still remain unidentified within the collections of the MNHN. Although this inventory is incomplete, we demonstrate that the deep waters of French Polynesia host unique benthic communities and endemic species. Using diversity and multivariate analyses, we show that the deep-sea benthic...

Defining a pelagic typology of the eastern English Channel ArchiMer
Delavenne, Juliette; Marchal, Paul; Vaz, Sandrine.
Classifying marine habitats is a growing research field and is of increasing interest to spatial planners and managers. Most studies have predominantly focused on the seabed to determine benthic habitat types, and only limited attention has been paid to the water column. Classification projects aim at identifying candidate management units for the application of various regional or national regulations such as the European Water Framework Directive. Here, we propose a seasonal classification of the water column in the eastern English Channel, which we validated with biological data. For the three tested compartments, phytoplankton, zooplankton and pelagic fishes, the validation results were satisfactory, with recall values (i.e. percentage of observations...

Impacts of data quality on the setting of conservation planning targets using the species-area relationship ArchiMer
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...

Quantitative mapping of fish habitat: A useful tool to design spatialised management measures and marine protected area with fishery objectives ArchiMer
Le Pape, O.; Delavenne, Juliette; Vaz, Sandrine.
The delineation of essential fish habitats is necessary to identify, design and prioritize efficient marine protected area (MPA) networks with fishery objectives, capable, in addition to other possible objectives and functions of MPAs, of sustaining the renewal of marine living resources. Both the methods available to map essential fish habitats and the usefulness of these maps are discussed in this paper. Generally, the first step to obtain maps of essential fish habitats consists in choosing one of the numerous existing statistical approaches to build robust habitat suitability models linking relevant descriptors of the marine environment to the spatial distribution of fish presence or density. When these descriptors are exhaustively known, i.e. maps...

Systematic conservation planning in the eastern English Channel: comparing the Marxan and Zonation decision-support tools ArchiMer
Delavenne, Juliette; Metcalfe, Kristian; Smith, Robert J.; Vaz, Sandrine; Martin, Corinne S.; Dupuis, Ludovic; Coppin, Franck; Carpentier, Andre.
The systematic conservation approach is now commonly used for the design of efficient marine protected area (MPA) networks. Identifying these priority areas often involves using specific conservation-planning software. Several of these software programmes have been developed in recent years, each of which differs in the underlying algorithms used. Here, we investigate whether the choice of software influences the location of priority areas by comparing outputs from Marxan and Zonation, two widely used conservation-planning, decision-support tools. Using biological and socio-economic data from the eastern English Channel, we compared their outputs and showed that the two software packages identified similar sets of priority areas, even though the relatively...

The Channel habitat atlas for marine resource management (CHARM): an aid for planning and decision-making in an area under strong anthropogenic pressure ArchiMer
Martin, C. S.; Carpentier, Andre; Vaz, Sandrine; Coppin, Franck; Curet, L.; Dauvin, J. -c.; Delavenne, Juliette; Dewarumez, J. -m.; Dupuis, L.; Engelhard, G.; Ernande, Bruno; Foveau, A.; Garcia, C.; Gardel, Laure; Harrop, S.; Just, R.; Koubbi, P.; Lauria, Valentina; Meaden, G. J.; Morin, Jocelyne; Ota, Y.; Rostiaux, Emilie; Smith, R.; Spilmont, N.; Verin, Yves; Villanueva, Ching-maria; Warembourg, Caroline.
The eastern English Channel, the narrow channel of water separating northern France and southeast England is an area of intense human use of the array of resources concentrated into its relative small area. The vulnerability of living resources and their habitats brought together French and British maritime experts within a common project (called CHARM): to create an atlas of marine resource habitats in the eastern English Channel so as to provide planners and decision-makers with the necessary information to help managing the use of its living and non-living resources. This multidisciplinary and richly illustrated atlas provides abundant information on the legal framework and physical environment; benthic invertebrates, fish and their habitats; fishing...
