Figure 6.

(A) The contribution of deterministic (homogeneous and heterogeneous selections) and stochastic (dispersal limitations and homogenizing dispersal) processes to the assembly of abundant and rare subcommunities. (B) Pairwise correlations between environmental variables, and the Mantel tests between environmental variables vs. the beta nearest taxon index (βNTI). The lines denote the significant relationships with line width representing the Mantel r statistic. Pairwise correlations between environmental variables are shown in the heatmap matrix denoting Pearson's correlation coefficient. The significant results are shown in numbers. The abbreviations of the environmental variables are explained in the Methods section.
