Soil pH and temperature regulate assembly processes of abundant and rare bacterial communities in agricultural ecosystems

The factors determining stochastic and deterministic processes that drive microbial community structure, specifically the balance of abundant and rare bacterial taxa, remain underexplored. Here we examined biogeographic patterns of abundant and rare bacterial taxa and explored environmental factors influencing their community assembly processes in agricultural fields across eastern China. More phylogenetic turnover correlating with spatial distance was observed in abundant than rare sub-communities. Homogeneous selection was the main assembly process for both the abundant and rare sub-communities; however, the abundant sub-community was more tightly clustered phylogenetically and was more sensitive to…
