The diversity of bacteria present in surface snow around four Russian stations in Eastern
Antarctica was studied by high throughput sequencing of amplified 16S rRNA gene …

Microbial ecology is the study of microbes in the natural environment and their interactions
with each other. Investigating the nature of microorganisms residing within a specific habitat …

During the summer months, wet (hyporheic) soils associated with ephemeral streams and
lake edges in the Antarctic Dry Valleys (DVs) become hotspots of biological activity and are …
