Grazing intensity is one of the crucial anthropogenic activities on alpine grasslands. However, how grazing affects soil microorganism diversities and their co-occurrence networks in steppe remains uncertain. We carried out a controlled experiment (null grazing, CK; moderate MG; heavy HG) typical Lhasa River Basin, Central Tibet, China. used high-throughput sequencing to find sequences bacterial 16S rRNA fungal ITS gene amplicons. Then, we analyzed alpha beta set up that show often they occur together. MG significantly increased Shannon index changed community structure. In contrast, HG decreased ACE Chao1 indices also structure (p < 0.05). Linear mixed-effect model revealed available phosphorus impacted Shannon, ACE, across intensities, while total carbon subsoil affected these indicators fungi. Moreover, complexity network community, simplified it. both made less complicated. This shows has different impacts microbes interact with each other. Therefore, sustainable necessitates deeper understanding biodiversity conservation

Background Alpine grassland degradation on the Tibetan Plateau has become an important ecological and environmental problem in recent years, changed diversity of aboveground plants ecology underground soil. As part soil ecosystem, fungi play a positive role health plant growth by decomposing organic matter, constructing mycorrhizal symbiosis system secreting antibiotics. Results In this study, high-throughput sequencing technology was used to compare fungal communities natural, degraded desertified grasslands, explore effects alpine adaptation mechanism degradation. Conclusions The study found that altered increased risk potential disease.
