Fit of the neutral community model of community assemblies

(A) the bulk soil microorganisms in 2017 (n = 12); (B) the rhizosphere microorganisms of toxic plants in 2017 (n = 51); (C) non-toxic plants rhizosphere microorganisms in 2018 (n = 6); (D) rhizosphere microorganisms of toxic plants in 2018 (n = 21). The solid blue lines represent the best fit, and the dashed blue lines represent 0.95 confidence intervals around the model prediction. Different colors represent the frequency of OTUs. R² = the coefficient of determination, Nm = the meta-community size times immigration rate.
