Abstract

Species turnover is fundamental for understanding the mechanisms that influence large-scale species richness patterns. However, the large-scale spatial variation and the causes in soil animal species turnover remain elusive. In addition, the determinants of species turnover depend on the dispersal ability of guilds. In this study, we explored the large-scale patterns of meso-micro soil fauna turnover pattern and the driving factors based on fourteen sampling sites in East Asia. The patterns of soil fauna species turnover increased significantly with increasing latitude differences in East Asia. The environment explained 54.09, 50.62, and 57.34% of the total variance, and spatial factors explained 13.84, 15.91, and 21.04% of the total variance in species composition of overall, phytophage, and predacity faunas, respectively. Meanwhile, the effects of climate factors in environmental processes were stronger than that of soil factors in these three groups. Our results support the hypothesis that the effect of environment processes on soil animal species turnover is more important than the effect of the neutral. Climatic factors explained more variation for turnover of phytophage faunas, but soil and environment factors explained equally for predacity. Our results provide evidence supporting both environmental filtering and dispersal limitation hypotheses on the reginal and population scales. At last, this study has important theoretical significance and applied value in maintaining and promoting soil biodiversity and ecosystem services on the large scale.
