Microbiology of the dry valleys of Antarctica.
The Antarctic provides a natural environment which is more like that of Mars than any other locality on earth. Life in the dry valleys is almost entirely microbial, with dense populations of algae found on the lake shores. The algae support an ecology of bacteria, yeasts, molds, and protozoans; roti...
