Biodiversity and biogeography of Antarctic and sub-Antarctic mollusca

This paper reports the results of the most comprehensive analysis so far of diversity patterns of a major phylum of the Antarctic marine fauna (molluscs). It is strongly cross discsiplinary, being a major product of SOMBASE and linking science in GSD and BSD. It shows for the first time new patterns in marine biodiversity in Antarctica, with patchiness at all scales of analysis, and strong variations in endemism with region.

It resulted in the finding of 3 major distinct biogeographical regions: the Continental high Antarctic, the Scotia Sea (including the peninsula), and the sub Antarctic province. It also found sites that were “hotspots” for biodiversity and also transition zones of diversity not previously identified. It is a step forwards in our understanding of such patterns in the seas around Antarctica.
