Biogeography and biodiversity of gastropod molluscs from the eastern Brazilian continental shelf and slope

Biogeographic distributional patterns of gastropods are proposed based on the species' geo-graphic and bathymetric distribution. Samples were collected along the Brazilian continental margin between 18° S and 23° S, at 37 stations with depths from 20 m to 1,330 m. The analysis of the biogeograp...
