The biogeographical mapping of Antarctic echinoids (south of latitude 35° S) is being performed using both data from literature and new records from the numerous recent cruise campaigns around Antarctica. The second step and objective of our work is to identify and characterize the main factors that control echinoid distribution in the Antarctic. To obtain a comprehensive model of echinoid biogeographical and macroecological patterns, physical data are matched to echinoid distribution using GIS. Two alternative hypotheses will be tested: (1) is Antarctic echinoid distribution controlled by environmental and physical factors such as water temperature, sediments and depth (the environmental hypothesis) or (2) is echinoid distribution best explained by historical biogeography (the provincialist hypothesis)?
