Influence of Interspecies Interactions on Bacterial Community Assembly in the Active and Permafrost Layers on the Qinghai-Tibet Plateau.

Bacterial communities play a crucial role in permafrost biogeochemical cycling and ecosystem function maintenance. Bacterial interaction is one of the main factors in shaping soil bacterial communities. However, how would bacterial interaction influence the bacterial communities in permafrost of the Qinghai-Tibet Plateau (QTP) remains largely unknown. Here we collected paired soil samples from both the active and permafrost layers of two typical QTP permafrost regions in October 2020 for Tuotuohe River (TTH) and May 2022 for Aerjin (ARJ), and investigated the bacterial communities and the role of interactions in structuring the bacterial community and its assembly process through amplicon sequencing of the 16S rRNA gene. Our study revealed distinct bacterial communities, with significant differences in the relative abundances of Proteobacteria (
