摘      要：Background:Soil fungi play crucial roles in ecosystem ***,how snow cover change associated with winter warming affects soil fungal communities remains unclear in the Tibetan ***:We conducted a snow manipulation experiment to explore immediate and legacy effects of snow exclusion on soil fungal community diversity and composition in a spruce forest on the eastern Tibetan *** fungal communities were performed by the high throughput sequencing of ***:Ascomycota and Basidiomycota were the two dominant fungal phyla and Archaeorhizomyces,Aspergillus and Amanita were the three most common genera across seasons and snow *** exclusion did not affect the diversity and structure of soil fungal community in both snow-covered and snow-free ***,the relative abundance of some fungal communities was different among *** fungal groups were correlated with environmental factors(i.e.,temperature and moisture)and soil biochemical variables(i.e.,ammonium and enzyme).Conclusions:These results suggest that the season-driven variations had stronger impacts on soil fungal community than short-term snow cover *** findings may have important implications for soil microbial processes in Tibetan forests experiencing significant decreases in snowfall.
