Comparison of seasonal soil microbial process in snow-covered temperate ecosystems of northern China.

More than half of the earth's terrestrial surface currently experiences seasonal snow cover and soil frost. Winter compositional and functional investigations in soil microbial community are frequently conducted in alpine tundra and boreal forest ecosystems. However, little information on winte...
