Linear regression analyses of the residuals of snout-to-vent-length on each environmental predictor exhibiting factor loadings >0.7 in significant PCs (see Table 4).

Residuals of snout-to-vent-length (denoted as e in the formulation of methods) express the portion of SVL that was not explained by the unshared variation between ecology and phylogeny. Bold lettering denotes P-values<0.05. See methods for details. b: denotes standardized regression coefficients.
