Diversity Patterns of Modern Arctic and Antarctic Bryozoans
A comparison of Arctic Sea and Antarctic Sea bryozoan faunas (cheilostomes) was conducted by compiling comprehensive data sets from both realms [1, 2] and own additional collections from the European Sector of the Arctic Realm. The analysis documents the high endemism in Antarctic faunas also indica...
