Dew And Frost Do Not Serve As Water Sources For Rock-dwelling Organisms In The Dry Valleys Of Antarctica
Rock-dwelling chlorolichens and cyanobacteria provide most of the total biomass of the ice-free zone of Antarctica, i.e., the McMurdo Dry Valleys (MDV), and yet, the water sources of MDV are […]

The Antarctic Dry Valley Lakes: Relevance To Mars
The similarity of the early environments of Mars and Earth, and the biological evolution which occurred on early Earth, motivates exobiologists to seriously consider the possibility of an early Martian […]
