High intensity human activity limits ultra-high altitude soil microbial community dispersal and keystone taxa distribution in southeastern Tibetan Plateau.

ABSTRACT: Increasing human activities have caused ecological damage to the environment, especially in the ecologically sensitive alpine regions such as the southeastern Tibetan Plateau. However, how different intensities of human activities in the alpine regions affect the community assembly process of soil microorganisms and the distribution of keystone taxa remains unclear. This study examines the relationship between human activity intensity and soil microbial dynamics in three different Human Footprint Index (HFI) regions. The microbial community structure and assembly processes were investigated within over 200 km from Gongbo'gyamda County to Bayi District in the southeastern section of Tibet. The results show that human activities changed the content of soil nitrogen (r = 0.50) and phos
