Rapid Response to Experimental Warming of a Microbial Community Inhabiting High Arctic Patterned Ground Soil
The influence of climate change on microbial communities inhabiting the sparsely vegetated patterned ground soils that are widespread across the High Arctic is poorly understood. Here, in a four-year experiment on Svalbard, we warmed patterned ground soil with open top chambers and biannually irriga...
