WAP workshop Nov 2009 H.J. Griffiths, R. Grant & K. Linse

Where are the local diversity hotspots on the Antarctic Peninsula (AP)? What are their biological, geological and oceanographic signatures/characteristics? –Biology Do different taxa have same hotspots for species richness Do planktonic and benthic taxa share hotspots –Geology What is the history of the area (tectonics, volcanic activity, …) What is the glacial history; which local areas were covered/uncovered by ice shelf during the last glacial maxima/what were the ice shelf extant/ marine refugia present? –Oceanography What are the past/present current regimes in the region What water masses influence the area How are oceanographically linked factors (T, S,…) and nutrients (e.g. silica, phytoplankton,…) distributed Do the biological hotspots link with oceanographic/geological characteristics WAP workshop Nov 2009

Species richness hotspots: Raw data Species richness hotspots: Residuals
