Effects of Grazing Exclusion on Microbial Community Diversity and Soil Metabolism in Desert Grasslands

In this study, the effect of 14 years GE exclusion in a desert grassland on soil microbial community diversity and metabolites was examined. changed bacterial structure, alpha community, total phosphorus (TP) potassium (TK) content soil. More specifically, relative abundance Actinobacteria, Proteobacteria, Chloroflexi increased with GE. contrast, Acidobacteria higher during grazing (G), so it is believed that bacteria adapt to environmental changes. Both amino acid carbohydrate metabolism were enhanced, while lipid decreased under It concluded could trigger changes both metabolites, increase energy supply, regulate ecosystem function. Consequently, would have positive effects restoration grasslands by altering community. This work provides new insights into response microbes
