Responses of soil fauna community under changing environmental conditions

Abstract Soil faunas account for 23% of known animal species and play a crucial role in ecosystem processes such as mineralizing nutrients, regulating microbial community composition, forming soil aggregates, enhancing primary productivity. However, due to global climate change, population density, distribution patterns fauna vary. Understanding the responses major environmental change facilitate conservation biodiversity. Therefore, review work recent researches analysing effects key factors on fauna, warming, drought, food quality, physical-chemical properties was studied. For most species, warming may exert positive effect their abundance development, however, it can inhibit survival reproduction hibernating species. Drought leads low porosity water holding capacity, which reduces changes composition. also reduce coverage flora alter microclimate surface, turn indirectly abundance. Climate elevated atmospheric carbon dioxide litter will force dietary choices (from higher-quality foods poor quality foods) survival. is still predicted that enhanced richness plant (or litter) mixtures positively affect diversity. Habitat loss caused by deterioration property factor affecting fauna. We mainly discuss threats increased salinity (a arid land) potential anthropogenic disturbance saline soils. The increase override other favour habitat specialists, leading negative Moreover, we find more studies are needed explore soils human activities. And relationship important ecological with structure, diversity needs be redefined.
