Comparative biogeography of echinoids, bivalves and gastropods from the Southern Ocean.
International audience Aim Biogeographical patterns within three classes, the Echinoidea, Bivalvia and Gastropoda, were investigated in Antarctic, sub-Antarctic and cold-temperate areas based on species occurrence data. Faunal similarities among regions were analysed to: (1) test the robustness of t...
