The research team prepares to take samples near Lake Bonney in the Taylor Valley Climate Change In The McMurdo Dry Valleys

Tuesday April 24, 2018

The McMurdo Dry Valleys ecosystems are changing because of climate change. In a paper published in the journal Ecology in January researchers said they've tracked the decline of the microorganism living in the Dry Valleys' barren soils. More frequent extreme weather events are driving down the population of the nematode Scottnema lindsayae, a microscopic roundworm, which makes up about 90 percent of the species that live in the Dry Valleys.

Evolutionary biologist Paul Cziko from the University of Oregon is studying how Antarctic fish don’t, themselves, freeze into a solid block while spending their lives in subzero waters.
