Coefficients of determination of Phylogenetic Eigenvector Regression (PVR) models for the different lineages studied. Variable codes as in Table 2. Size, range size (log-transformed). Models with significant P-values are indicated with asterisks: * P < 0.05; ** P < 0.005 (Bonferroni critical value for ten tests).
