Which factors are shaping the microbial diversity in the inland high-altitude biotopes of the Western Sør Rondane Mountains (Eastern Antarctica, ACBR6)?
The scarce ice-free terrestrial areas of Antarctica are among the most extreme environments on Earth and are therefore dominated by microorganisms. The BelSPO project BELDIVA (2009-2912) investigated soil and biological crusts’ microbiomes in the vicinity of the Princess Elisabeth Station using ampl...
