Differences in bacterial diversity, composition, and community networks in lake water across three distinct regions on the Qinghai-Tibet Plateau

Bacterial diversity and composition in lake water vary significantly across three distinct regions on the Qinghai-Tibet Plateau (QTP): Hoh Xil (HX), Yellow River Headwater (YRH), and Qaidam (QD). HX exhibits markedly lower bacterial alpha-diversity compared to YRH and QD, with Bacteroidetes dominating in HX (46.07%) while Proteobacteria are predominant in QD (42.45%) and YRH (43.64%). Environmental factors such as altitude, total nitrogen, and pH play crucial roles in shaping bacterial communities, with altitude being the most influential in QD, total nitrogen in YRH, and pH in HX. Spatial factors also significantly impact bacterial composition in QD and HX, whereas environmental factors alone drive community structure in YRH. Network analyses reveal that while QD's bacterial network is the most complex, HX's network exhibits the highest stability, followed by QD and YRH.
