Abundances and metabolism in the Northern Victoria Land and Upper Victoria Valley
Permafrost hosts a potentially large pool of microorganisms, which is supposed to be the only life forms known to have retained viability over geological time. Thawing of the permafrost renews their physiological activity and exposes ancient life to modern ecosystems (Gilichinsky et al, 2008). The adaptation mechanisms of microorganisms, at species or population level, make them susceptible to extreme environmental conditions. The survival of microorganisms in permafrost raises the question of what constitutes the limit for microbial life (Steven et al., 2006; Wagner 2008).

- Purpose
-
Aim of work is devoted to test the hypothesis that Continental Antarctic permafrost harboured prokaryotic communities rich in viable cells and metabolic potentials. This study focused on three permafrost environments of the Northern Victoria Land: Boulder Clay (Continental Antarctica) and one more sample collected in the Dry Valleys (Upper Victoria Valley). The aims of this paper were to establish 1) how much prokaryotic cells inhabited the studied permafrost, 2) how much were alive and respiring, 3) which metabolic activities they could potentially carry out, and 4) the differences in the microbial behaviour, if there were, on a layer gradient.
