Controlling factors for soil bacterial and fungal diversity and composition vary with vegetation types in alpine grasslands

Soil microbes have vital functions in terrestrial ecosystems, but the concurrent effects of soil microclimates, edaphic attributes, and plant properties on soil microbial diversity and community composition are rarely evaluated for different vegetation types. Here, we investigated the individual and interactive effects of these controlling factors on soil bacterial and fungal diversity and community composition in alpine meadow and alpine steppe on the Tibetan Plateau.
