Abstract Background Soil erosion affects the stability of terrestrial ecosystems and ecosystem services by directly or indirectly impacting cycling soil materials energy reducing fertility grassland soils. However, research on microbial adaptation to grazing is limited, particularly in relation restoration. Here, we assess communities subjected simulated a semi-arid Inner Mongolia, China. Results No significant change was observed variables. structure community underwent changes as result plus grazing, leading increase relative abundance Cyanobacteria (116.80% vs 116.38%). Wind deposition contributed an network complexity bacterial fungal communities. much this effect alleviated grazing. Simultaneously, aeolian processes regulate assembly, inconsistent patterns Under wind deposition, contribution deterministic (4.44% 31.11%) increased, while stochastic (2.23% 20%) reduced. Grazing resulted decrease (8.89%) community. Conclusion This study presents comprehensive investigation response erosion–deposition grassland. Our findings indicate that show resistance external disturbances light mitigates effects communities, which essential for maintaining biodiversity ecosystems.

Intensive agricultural management affects the physical, chemical, and biological properties of soil, potentially contributing to a decrease in soil carbon storage. In this study, effects intensity on organic (SOC) content its labile fractions, i.e., water-soluble (OC-sol) permanganate oxidizable (POXC), were evaluated volcanic-ash-derived (Andisol) with very high matter (SOM) (>20%). These indicators associated water-stable aggregates (WSAs) indicators, namely, earthworm density, cellulase activity, autoclaved-citrate-extractable (ACE) proteins, related decomposition SOM physical protection. The conditions secondary native forest (SF), naturalized grassland (NG), no-till (NT), conventional tillage (CT), considering last item be representative higher agriculture intensity. Soil samples collected by horizon. SF NG showed contents SOC, OC-sol, POXC.

ABSTRACT Soil microbial diversity and community structure play pivotal roles in maintaining multiple ecosystem functions biogeochemical cycling. However, the patterns mechanisms of grazing effects on bacterial fungal remain poorly understood a broad scale. To address this issue, we conducted meta‐analysis by compiling comprehensive dataset consisting 543 paired observations from 48 manipulative experiments grassland ecosystems. Pooling all data, our results indicated that significantly altered soil structure, almost uniformly decreased beta diversity, did not change alpha diversity. intensity had different communities, with more pronounced alterations community. Moreover, showed positive response to cattle/yak short‐term (e.g., less than 5 years), while sheep long‐term negative Model‐selection analysis further suggested changes organic carbon (SOC), total nitrogen (TN), pH, duration, livestock type jointly regulated responses disturbances. Our findings underscore divergent Appropriate selection cattle), short moderate can help maintain stability communities functions. These insights are crucial for establishing precision management strategies, promoting sustainability

Grassland management affects soil respiration (Rs, consists of heterotrophic and autotrophic respiration) through micro-ecological processes, such as hydrothermal, plant root, organic carbon decomposition microbial activity. Flooding, an irregular phenomenon in grasslands, may strongly regulate the response its components to grassland management, but regulatory mechanism remains unclear. We conducted a 3-year experiment by (fencing grazing) flooding conditions (no (NF), short-term (STF) long-term (LTF)) study their effects on Rs meadow steppe Hui River basin Hulunbuir. found differences patterns under conditions. In 2021–2023, temporal trends Rs, (Rh) (Ra) were generally consistent, with peaks occurring days 190–220, grazing higher than that fencing. NF, grazed was significantly fenced 2021–2022 (p < 0.05).
