ABSTRACT Litter decomposition is critical for maintaining productivity and nutrient cycling in forest ecosystems. Large herbivores play an essential role determining the processes of cycling. Asian temperate forests are becoming degraded fragmented by widespread intensification anthropogenic activities, including excessive livestock grazing. However, effects grazing wild ungulates on litter remain less explored. In this study, we used a litterbag experiment to investigate addition cattle ( Bos taurus ) sika deer Cervus nippon feces decomposition. The study was conducted Northeast China from July 2022 October 2023. We found that significantly reduced decomposition, but greatly increased presence excrement accelerated release C after 1 year Compared with results control group (no feces), 37.45% 22.69%, respectively.

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

ABSTRACT Large herbivore grazing plays a key role in regulating ecosystem functioning and nutrient cycling terrestrial ecosystems. However, the effects mechanisms of large intensity on soil fractions remain largely unclear alpine grasslands. Here, we determine 20 indicator variables associated with (e.g., particulate organic carbon, POC; mineral‐associated MAOC) to investigate how labile through well‐controlled experiment an meadow eastern Tibetan Plateau. Our results show that microbial biomass dissolved light fraction nitrogen phosphorus, total potassium, available potassium significantly decrease increased intensity, whereas other POC, MAOC, nitrogen, ammonium nitrate etc.) have marginal or non‐significant responses intensity. Further analysis reveals above‐and below‐ground biomass, moisture, pH jointly fractions, without impact species richness. Moreover, correlation analyses indicate decouples carbon from phosphorus meadows. Collectively, our emphasize importance grasslands incorporate impacts into models may help accurately predict sequestration potential grazinglands.

The degradation of temperate desert type rangeland leads to decreased vegetation diversity and soil nutrients levels. Grazing prohibition artificial revegetation are common strategies for restoration. However, it is currently unknown the duration grazing affect microorganisms. Therefore, experiments on were conducted explore response microorganisms these measures. Field during peak plant growth season in Guide County, China, evaluate methods involving revegetation. We established six experimental sites, which fifteen years (P15), land located near P15 (P15-CK), eight (P8), P8 (P8-CK), three (A3), wasteland A3 (A3-CK). results showed that measures diversity, whereas increased it. Artificial led an increase pH total carbon, a decrease nitrogen phosphorus. amount PLFA with revegetation, resulted PLFA. relative abundance Ascomycota phylum fungal diversity. In addition, study found communities primarily influenced by factors such as ammonium nitrogen, pH, rather than plants. Vegetation restoration enhances accumulation carbon alters community composition effects varied. These findings provide important information promotes nutrient but reduces can inform degraded rangeland.

ABSTRACT Plant community construction is influenced by bottom‐up processes, such as environmental factors, and top‐down herbivore disturbances. With climate change overgrazing, the stability of plant structure function decreases, more land at risk degradation. However, response to interference from native herbivores under similar conditions remains unclear. Plateau pika ( Ochotona curzoniae ) an important small rodent inhabiting alpine meadow Qinghai‐Tibetan Plateau, its disturbance may accelerate degradation grassland ecosystems when population experiences a burst. In this study, we investigated communities, collected analyzed soil samples, explore effects plateau pikas' intensity on species composition phylogenetic communities meadow. We utilized generalized additive model structural equation explain predict competition pikas. Our results indicated that altered dominance groups, increased substitution, facilitated coexistence among different species, it affected deterministic reduced interspecific intensity, promoted dispersion structures. These findings suggested pika, herbivore, plays significant role in fostering multi‐species communities. Therefore, essential manage maintain well influence long‐term succession ecosystems. This study provides some new evidence for exploring changes
