Figure 2. Patterns of Net relatedness index (NRI a,b) and Nearest Taxon Index (NTI c,d).
(a,c) patterns across six successional stages and (b,d) for herbaceous and woody plants in the late three successional stages. Specifically NRI or NTI <0 represents phylogenetic divergence, while NRI or NTI >0 indicates phylogenetic convergence. Asterisks indicate overall significance according to two-tailed t-tests (p < 0.05). See Methods for details.
