Habitats et communautés benthiques du bassin oriental de la Manche : état des lieux au début du XXIe siècle ArchiMer
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...

Bases scientifiques et techniques d’un observatoire du changement global en mer ArchiMer
Andral, Bruno.
La Méditerranée constitue un des pôles mondiaux de biodiversité et un lieu clé des changements climatiques globaux, avec des taux de réchauffement constatés en surface parmi les plus élevés de la planète (~+ 0.06°C/an). Nous pouvons en constater aujourd’hui les premiers symptômes : transformation des écosystèmes et habitats, augmentation de la température de l’eau et son cortège d’espèces exotiques, espèces invasives animales et végétales et leurs impacts sur les espèces indigènes. Les îles, par leur taille, et du fait qu’elles sont moins soumises aux pressions anthropiques directes, sont des laboratoires idéaux pour suivre l’impact des changements globaux sur la biodiversité, sans être perturbé par des effets locaux. Dans le cadre de l'initiative "Petites...

Shallow rocky bottom benthic assemblages as calcium carbonate producers in the Alboran Sea (southwestern Mediterranean) ArchiMer
Cebrian, E; Ballesteros, E; Canals, M.
Zonation patterns and species composition of the different assemblages encountered along the bathymetric axis are considered in order to quantify the biomass and calcium carbonate content of communities thriving in rocky bottoms of La Herradura (southwestern Mediterranean) between 0 and 50 m depth. Algal biomass is lower but total biomass is slightly higher to values recorded in other Mediterranean areas due to the high biomass of suspension feeders. Since most of the animals and algae with high biomass have calcareous skeletons, the calcimass is rather high (1 100 to 2400 g . CaCO3.m(-2)) when compared to other temperate and Mediterranean sites. A tentative estimate of yearly carbonate production yields 1 000 g . CaCO3.m(-2).y(-1) for the rocky bottoms of...
