Disentangling the biogeographic patterns of rare and abundant microbes is essential in order to understand generation maintenance microbial diversity with respect functions they provide. However, little known about ecological assembly processes environmental adaptation across large spatial-scale wetlands. Using Illumina sequencing multiple statistical analyses, we characterized taxonomic phylogenetic bacteria fungi Qinghai-Tibet Plateau wetland soils. Abundant taxa exhibited broader thresholds stronger signals for traits than ones. By contrast, showed higher sensitivity changes closer clustering The null model analysis revealed that dispersal limitation belonging stochastic process dominated community assemblies bacteria, fungi, while variable selection deterministic governed bacteria. Neutral variation partitioning further confirmed were less environmentally constrained. Soil ammonia nitrogen was crucial factor mediating balance between stochasticity determinism both microbes. may have better potential are dispersed by Our findings extend knowledge ongoing change could facilitate prediction biodiversity loss caused probably climate human activity
