Climate change causes declines in soil fauna in the McMurdo Dry Valleys

Results from a multi-decadal study led by MCM LTER researchers at Colorado State University have discovered changes in soil fauna biodiversity as a result of glacial and permafrost ice melt caused by climate change. Lead author Walter Andriuzzi states, "in 2001, the cooling trend stopped abruptly with an extremely warm weather event. Since then, the average temperatures are either stable or are increasing slightly. But most importantly, there have been more frequent intense weather events." Higher temperatures have led to the decline of the most common species, nematode Scottnema lindsayae, while other species are becoming more abundant, particularly at higher elevations.
