Large amounts of carbon sequestered in permafrost on the Tibetan Plateau (TP) are becoming vulnerable to microbial decomposition a warming world. However, knowledge about how responsible community responds warming-induced thaw TP is still limited. This study aimed conduct comprehensive comparison communities and their functional potential active layer thawing TP. We found that were diverse varied across soil profiles. The diversity declined relative abundance Chloroflexi, Bacteroidetes, Euryarchaeota, Bathyarchaeota significantly increased with thawing. Moreover, reduced similarity stability communities. high-throughput qPCR results showed genes involved liable degradation methanogenesis Notably, mcrA gene higher methanogens methanotrophs ratio implied enhanced methanogenic activities during Overall, composition potentials region susceptible warming. These changes may accelerate degradation, particularly methane releases from alpine ecosystems
