Groundwater bacterial and fungal diversity on the permafrost regions of Qinghai-Tibet Plateau

The ongoing permafrost degradation under climate warming has modified aboveground biogeochemical processes mediated by microbes, yet groundwater microbial structure and function as well as their response to permafrost degradation remain poorly understood. Therefore, we separately collect 20 and 22 sub-permafrost pristine groundwater samples from Qilian Mountain (QM) and Southern Tibet Valley (TV) on the Qinghai-Tibet Plateau (QTP) to investigate the effects of permafrost groundwater characteristics on the diversity, structure, stability, and potential function of bacterial and fungal communities.

气候变暖背景下持续发生的多年冻土（permafrost）退化，已改变了微生物介导的地上生物地球化学过程，但目前学界对地下水微生物的群落结构、功能及其对多年冻土退化的响应机制仍缺乏深入认知。为此，本研究于青藏高原（Qinghai-Tibet Plateau, QTP）的祁连山（QM）与藏南谷地（TV）分别采集20份与22份冻土下原生地下水样本，以探究冻土地下水特征对细菌与真菌群落的多样性、结构、稳定性及潜在功能的影响。
