Influence of soil properties on archaeal diversity and distribution in the McMurdo Dry Valleys, Antarctica
Archaea are the least understood members of the microbial community in Antarctic mineral soils. Although their occurrence in Antarctic coastal soils has been previously documented, little is known about their distribution in soils across the McMurdo Dry Valleys, Victoria Land. In this study, termina...

Archaea are the least understood members of the microbial community in Antarctic mineral soils.
