Climate warming and high-intensity human activities threaten the stability of alpine meadow ecosystems. The soil microbial community is crucial for maintaining ecological service function. However, effects litter removal on interactions, community-building processes, species coexistence strategies remain unclear. In this study, we used a fiberglass open-top chamber to simulate global change, moderate grazing in winter was simulated by removing above-ground from all plants Qinghai-Tibet Plateau, China, investigate warming, removal, interactions communities. treatments included (1) treatment (W); (2) (L); (3) combined (WL); (4) control (CK). results show that compared with treatment, increased bacterial Shannon diversity but reduced fungal diversity, significantly changed composition. Warming, colinear network connectivity among microorganisms modularity network, average path distance clustering coefficient were higher than those group. Stochastic processes played more important role shaping composition, soil-available phosphorus ammonium contributed βNTI community, while total NAG enzyme community. Notably, counteracts These suggest may enhance under conditions, providing insights managing ecosystems context climate change.

Mining significantly impacts terrestrial ecosystems despite its importance to the global economy. As part of soil ecosystems, fungi are highly responsive environmental and human-induced drivers, shifting community composition structure. Indeed, play a key role in maintaining ecosystem resilience. Thus, we aim address question whether fungal communities maintain similar ecological functions changes due impact mining across ecosystems. To evaluate four with varying iron levels, used FUNGuild database assign functional guilds at genus level. Co-occurrence network ordination analyses were infer relationships among taxa visualize correlation between edaphic properties communities. A total 22 identified, dung saprotrophs, wood parasites, plant pathogens, ectomycorrhizal fungi, animal endophytes being most abundant. Soil such as pH, organic matter, texture, nutrients drive taxonomic shifts. Our findings indicate that while activities shift compositions profiles show overlap highly, moderately, lowly impacted indicating redundancy. Network analysis reveals connected hub contribute redundancy might act buffer against disturbances. emphasize important potential for using bioindicators recovery post-mining landscapes. From restoration perspective, this offers low-cost, ecologically meaningful tool monitoring guiding reclamation efforts.
