From Subantarctica to Antarctica, a testate amoebae biogeography overview
International audience Testate amoebae are ubiquitous single cell organisms living in all soil and freshwater environments. A synthesis of 341 samples from Antarctica and Subantarctica, collected from 1901 to 2013, gave 304 species.One group with six islands was underlined: Falkland, Marion, Livings...
