%X Aims Snowpack plant communities in alpine tundra are active in comparison with surrounding vegetation, despite the short growing season due to thick snow cover. Our objective was to understand the growth mechanism of snowpack communities. Methods The nutrient dynamics and primary productivity of snowpack Sanguisorba sitchensis community in alpine tundra of Changbai Mountain was investigated in different seasons. Important findings Soil temperature under snowpack during winter was warmer than snow-free areas...
