Multiple linear regression analyses of snout-to-vent-length on the ecological (PC) and phylogenetic (PV) factors, and on independent components, <i>i.e.</i> ecology independent of phylogenetic factors (ResPC) and phylogeny independent of ecological factors (ResPV).

Bold lettering denotes partial correlations significant at P < 0.05. Only the first two phylogenetic factors are shown for brevity, the remaining factors were not significant (See methods for details). b: denotes standardized regression coefficients.
