Abstract Soil microorganisms and their diversity are important bioindicators of soil carbon nutrient cycling. Land use type is a major determining factor that influences microbial community composition in floodplain ecosystems. However, how the structure communities respond to specific changes land use, as well main drivers these changes, still unclear. This study was conducted Yellow River examine effects on communities. Four types (shrubland, farmland, grassland forest) were selected, wherein shrubland served baseline. We measured using phospholipid fatty acids (PLFAs). significantly affected total, bacterial fungal PLFAs, gram-positive/negative PLFAs. Compared with shrubland, peanut farmland had higher total PLFAs forest pH phosphorus predominate explaining 37% 26% variability, respectively. nitrogen nitrate factors increasing diversity. Peanut highest content, stock, diversity, suggesting has great potential sink. Our findings indicated critical for maintaining sequestration.

Covering about 30% of the global total land area, desert ecosystems have been influenced by warming and nitrogen deposition. However, it remains unclear how respond to Therefore, we conducted a greenhouse experiment examine impacts N addition on plant–soil system Neotrinia splendens, dominant plant in ecosystem Northern China. Our findings revealed that low-N dose (N1) high-N additions (N2) increased biomass 22.83% 54.23%, respectively; meanwhile, moderate (T2) severe (T3) decreased 39.07% 45.47%, respectively. did not significantly affect C:N:P stoichiometry system.

Soil microorganisms are vital components of the karst terrestrial ecosystem. However, their responses to vegetation succession on mountain peaks remain unclear as whether soil microbial diversity and community compositions change with succession. We investigated bacteria fungi associated environmental factors along a from moss crusts (MC) sparse grasses (MCG) (G) peaks. The results indicated that organic carbon total nitrogen generally increased, pH changed in range 8.19–8.44 slightly declined Overall, there was an increase biomass succession, dominant phyla bacteria, including Proteobacteria, Acidobacteria, Actinobacteria, Choroflexi, Gemmatiomnadates, Bacteroidetes, Planctomycetes, dominated fungi, Basidiomycota Ascomycota. Notably, both bacterial fungal were different among three successional stages.

Different vegetation restoration methods may affect the soil’s physicochemical properties and microbial communities. However, it is not known how network’s complexity of bacterial fungal communities respond to short-term restoration. We conducted a ecological experiment reveal response community stability initial during degraded grassland ecosystem. The two (sowing alfalfa (Medicago sativa, AF) smooth brome (Bromus inermis, SB)) had no significant effect on alpha diversity community, but SB significantly increased soil surface (p < 0.01). results NMDS showed that were altered by restoration, they available phosphorus (AP), potassium (AK), nitrate nitrogen (nitrate-N) closely related changes in Moreover, fungi networks, opposite was case with bacteria.
