Evaluation de la sensibilité des habitats benthiques de Méditerranée aux pressions physiques ArchiMer
La Riviere, M; Michez, M; Aish, A; Bellan-santini, D; Bellan, G; Chevaldonne, P; Dauvin, Jc; Derrien-courtel, S; Grall, J; Guerin, L; Janson, Al; Labrune, C; Sartoretto, Stephane; Thibaut, T; Thiebaut, E; Verlaque, M.
Le Ministère de l’Ecologie, de l’Energie et de la Mer a confié au Service du Patrimoine Naturel (Muséum National d’Histoire Naturelle), en lien étroit avec les acteurs de la recherche scientifique, la coordination d’un projet sur l’évaluation de la sensibilité des habitats benthiques aux pressions d’origine anthropique. L’objectif de ce travail est de qualifier la sensibilité générique des habitats présents en France métropolitaine pour aider à l’orientation et à la priorisation de mesures de gestion (pour des activités actuelles ou futures), adaptées aux enjeux de conservation, afin de respecter les objectifs d’atteinte ou de maintien d’un ECF (DCSMM) ou BEE (DHFF). Ce travail permet également de mettre en évidence les habitats et/ou les pressions pour...

Actualisation des donnees sur l'ecologie, la biogeographie et la phylogenie des Ampeliscidae (crustaces-amphipodes) Atlantiques apres la revision des collections d'E. Chevreux ArchiMer
Bellan-santini, D; Dauvin, J.
In the world, the Ampelisca genus is constituted by more than 140 species, which are found between 0 to 4000 m depth. Phylogeny, biology and ecology are the most important interest in this genus. The present analysis of new and older collections (E. Chevreux) have permitted to describe 11 new species. 41 species are listed in the north-eastern Atlantic fauna. These are different arguments to think that Ampelisca groups was actually in speciation. Two groups issued from a phenetic analysis are discriminated by their apomorphic levels. More than of the third are endemic species. 21 species are present only in one of the five biogeographic region. 23 species are limited to the continental shelf, 34 live up to the first 1000 meters and 4 are bathyal. 2 species...
