Diversity of Antarctic Echinoids and Ecoregions of the Southern Ocean
Abstract: Significant environmental changes have already been documented in the Southern Ocean (e.g. sea water temperature increase and salinity drop) but its marine life is still incompletely known given the heterogeneous nature of biogeographic data. However, to establish sustainable conservation...
