Short summary
Soil microbial communities play a key role in the cycling of carbon (C) in Arctic tundra ecosystems through decomposition of organic matter (OM). Climate change predictions include increased temperature and snow accumulation, resulting in altered plant communities and soil conditions. To determine how soil bacteria may respond, we sequenced soil DNA from a long-term snow depth treatment gradient in Alaska. Results indicate that bacteria produce less OM-degrading enzymes under deeper snowpack.
