Abstract In grassland ecosystems, large herbivorous animal grazing activity and increasing nitrogen deposition strongly alter microbial community structure function. Understanding the effects of addition on spatial heterogeneity in soil structure, enzymatic activities underlying mechanisms are crucial for making better predictions organic matter dynamics nutrient cycling. We examined associated with changes microclimate, characteristics, plant biomass responses to using a manipulative experiment control (CK), (G), (N) plus (NG) treatments Leymus chinensis meadow steppe, north‐eastern China. The results demonstrated that showed high level dependence [C/(C + C0) ≥ 0.9] CK plot. G, N NG not only reduced variability but also reshaped links between enzyme structure. Litter biomass, temperature nutrients (soil dissolved inorganic or carbon) explained 21%–27% treatment pH was strongest driver activities. Meanwhile, homogenization water content induced by determinant reduction combination physico‐chemical properties (bulk density, nitrogen), root 32%–43% G treatment, had additive total PLFAs homogenizing biomass. Plant were major drivers under NG. NG, change dominated addition. Regardless grazing, facilitated correlation Overall, our revealed pattern shift due addition, highlighting role has L. steppe.

The Tibetan cattle, indispensable·animals on the Qinghai-Tibet Plateau, have become a focal point for region’s economic development. As such, hybridization of these cattle has been recognized as pivotal strategy to enhance local industry. However, research gut microbiota hybrid remains scarce. Based this, we conducted comparative analysis and its functional implications across three distinct populations: two populations (Tibetan × Holstein TH Jersey TJ) one locoal population (BL). Bacteroidetes Firmicutes dominate all at phylum level. In addition, predominant phyla in BL were found be Cyanobacteria, Verrucomicrobiota, Actinobacteria, which may important reasons adaptability high-altitude environment Plateau. Further identified specific biomarkers associated with immune systems including Bacteroidales_RF16, Coriobacterium , Muribaculaceae. contrast, are primarily dominated by Oscillospiraceae Clostridia_UCG_014, TJ mainly Christensenellaceae Gammaproteobacteria. KEGG enrichment revealed that showed significant system, energy metabolism, amino acid metabolism-related pathways compared cattle. Overall, results suggest demonstrate enhanced indicate intestinal different altitudes breeds diverse structures functions. Our study presents new perspective role microbiome enhancement

Abstract Grasslands provide a number of ecosystem services for human society. Degradation grasslands results in the loss biodiversity and leads to deterioration functions. In order accurately assess influence grassland degradation on belowground ecosystems, we conducted experiments temperate steppe with different levels investigated soil quality biotic communities.

Grazing is one of the main human disturbance factors in alpine grassland on Qinghai-Tibet Plateau (QTP), which can directly or indirectly influence community structures and ecological functions ecosystems. However, despite extensive field grazing experiments, there currently no consensus how different management approaches affect diversity, soil carbon (C), nitrogen (N). Here, we conducted a meta-analysis 70 peer-reviewed publications to evaluate general response 11 variables related ecosystems plant diversity grazing. Overall, results showed that significantly increased species richness, Shannon-Wiener index, Pielou evenness index values by 9.89% (95% CI: 2.75-17.09%), 7.28% 1.68-13.62%), 3.74% 1.40-6.52%), respectively. Aboveground biomass (AGB) belowground (BGB) decreased, respectively, 41.91% -50.91 -32.88%) 17.68% -26.94 -8.52%). Soil organic (SOC), total (TN), C:N ratio, moisture decreased 13.06% -15.88 -10.15%), 12.62% -13.35 -8.61%), 3.27% -4.25 -2.09%), 20.75% -27.89 -13.61%), whereas, bulk density pH 17.46% 11.88-24.53%) 2.24% 1.01-3.64%), Specifically, moderate grazing, long-durations (>5 years), winter contributed increases index. AGB, BGB, SOC, TN, ratios decrease with enhanced intensity. The ratio SOC was positively associated AGB BGB but negatively Furthermore, effects TN varied duration, season, livestock type, type. findings suggest should synthesize other appropriate patterns, such as seasonal rotation and, furthermore, additional research QTP needed future.

Alpine grassland is the main ecosystem on Qinghai-Tibet Plateau (QTP). Degradation and restoration of alpine are related to function production, livelihood, wellbeing local people. Although a large number studies research degraded grassland, there debates about degradation patterns in different areas widely applicable ecological schemes due huge area QTP. In this study, we used meta-analysis method synthesize 80 individual published which were conducted examine aboveground underground characteristics non-degradation (ND), light (LD), moderate (MD), heavy (HD), extreme (ED) Results showed that biomass (AGB), belowground (BGB), Shannon-Wiener index (H'), soil moisture (SM), organic carbon (SOC), total nitrogen (TN), available (AN) gradually decreased along gradient, whereas bulk density (BD) pH increased. spite tendency desertification, losses other nutrients reduction enzymes, was no linear relationship between variations with gradient. Moreover, decreasing extent TN smaller higher precipitation temperature, AGB, SOC, larger corresponding variables stage ND during degradation. These findings suggest reseeding sward cleavage can be for grassland. Fencing fertilization lower temperature. Microbial enzymes should not restore scale QTP without detailed investigation analysis.
