McMurdo Dry Valleys, Landsat 7 imagery acquired on December 18, 1999. The Dry Valleys are so named because of their extremely low humidity and lack of snow or ice cover. They are also dry because, in this location, the mountains are sufficiently high that they block seaward-flowing ice from the East Antarctic Ice Sheet from reaching the Ross ...
[2] [3] First described in 1971, it is endemic to Antarctica and most commonly found in the McMurdo Dry Valleys. S. lindsayae, a microscopic worm, feeds on microbes, including bacteria, yeast, and algae. [4] Adapted to very cold and dry climates, its population may be decreasing as a result of climate change.

The McMurdo dry valleys of Antarctica, which lack water (whether rain, ice, or snow) much like a non-polar desert and even have such desert features as hypersaline lakes and intermittent streams that resemble (except for being frozen at their surfaces) hot or cold deserts for extreme aridity and lack of precipitation of any kind. Extreme winds ...
The fennec fox's large ears help keep it cool: when the blood vessels dilate, blood from the body cycles in and dissipates over the expanded surface area. [1]A xerocole (from Greek xēros / ˈ z ɪ r oʊ s / 'dry' and Latin col(ere) 'to inhabit'), [2] [3] [4] is a general term referring to any animal that is adapted to live in a desert.
It turns desert into wealth, wealth into carbon, and carbon into intensifying, deadly heat. And standing in its path: scattered oryx, a heard of gazelle, a fox at dawn. Three scientists and some ...
Conversely, the McMurdo Dry Valleys of Antarctica, although they have had no ice for thousands of years due to katabatic wind but contain ephemeral streams and hypersaline lakes characteristic of extreme non-polar deserts, are not necessarily polar desert. [citation needed] Polar deserts are relatively common during ice ages, as ice ages tend ...
