Fig. 1: Community assembly processes for bacterial and fungal communities in ‘reference’ and historically ‘disturbed’ forest soils.
From: Historical land use has long-term effects on microbial community assembly processes in forest soils
In (A), βNTI distributions for bacteria and fungi are shown, while (B) and (C) show proportions of community assembly processes between historical land uses for bacteria and fungi, respectively. In all panels, shades of blue represent selection processes while shades of red represent neutral processes. In (A), phylogenetic turnover that is less than null expectations (i.e., βNTI < −2) indicates homogenous selection, phylogenetic turnover that is greater than null expectations (i.e., βNTI > 2) indicates variable selection, and phylogenetic turnover that does not vary from null expectations (|βNTI | < 2) indicates neutral processes. In (A) the P value is from a Kruskal–Wallis test. In (B) and (C), asterisks represent statistically greater proportions (Z-tests) at the following significance levels: *P < 0.05, ***P < 0.001. In (B), selection overall (i.e., homogeneous + variable) is greater in disturbed soil communities (P = 0.046).
