It is critical to identify the community assembly patterns (i.e., deterministic or stochastic processes) of soil microbes and the potential driving factors to better predict the belowground biodiversity and functioning in forest ecosystems. Here, a combined approach of neutral model and multivariate analysis was employed to examine the soil bacterial communities in 12 undisturbed forests in China, spanning a wide latitudinal range from 21.6°N to 50.8°N. A clear divergent pattern was found for community composition, indicating that deterministic processes dominated the community assembly of soil bacteria. The α-diversity (richness) nonlinearly changed from tropical to cold temperate zones, wi..View full abstract
