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.

Notably, counteracts These suggest may enhance under conditions, providing insights managing ecosystems context climate change.

Thinning-a widely used forest management practice-can significantly influence soil nitrogen (N) cycling processes in subtropical forests. However, the effects of different thinning intensities on nitrification, denitrification, and their relationships with properties microbial communities remain poorly understood. Here, we conducted a study China applied three treatments, i.e., no (0 %), intermediate (10-15 heavy (20-25 investigated intensity potential nitrification rate (PNR), denitrification (PDR), communities. Moreover, explored among physicochemical properties, community structure, transformation rates under intensities. Our results showed that increased PNR by 87 % 61 decreased PDR 31 50 compared to control, respectively. Although bacterial structure was markedly influenced thinning, fungal remained stable. Importantly, changes composition diversity had minimal impacts processes, whereas such as pH, organic carbon content, forms, were identified primary drivers. These findings highlight critical role managing regulate transformations soils. Effective should focus precisely adjusting enhance conditions, thereby promoting more efficient improving ecosystem health regions.

The preparation of artificial soil is a potential cooperative resource utilization scheme for red mud and phosphogypsum on large scale, with low cost simple operation. characteristics the bacterial community structure function in three soils were systematically studied first time. Relatively rich communities formed soils, relatively high abundances phyla (e.g.,

Fungal communities are critical players in the biogeochemical soil processes of forest ecosystems. However, factors driving their diversity and community assembly still unclear. In present study, five typical vegetation types fungal Liziping Nature Reserve, China, were investigated using ITS sequences. The results show that topsoil is mainly dominated by phyla Ascomycota, Basidiomycota, Mortierellomycota. Although there was no significant difference α (Shannon, Simpson, Pielou evenness indices) among different types, a β (community composition). This study found pH, organic carbon, total nitrogen (TN), phosphorus (TP), nitrogen/total (N/P) ratio main environmental affect communities. Each type has specific co-occurrence network, indicating these structures have specificities complexities. Deciduous evergreen broad-leaved forests as well deciduous mixed showed high modularity average path lengths, highly modular nature without distinct small-scale characteristics. Furthermore, our findings indicate shaped stochastic processes, with diffusion limitation mechanism playing particularly role.
