Table 1. Coefficients of determination of partial regression models of spider morphological variables (body size and flatness) against phylogenetic (PVR eigenvectors) and ecological (habitat and guild) components.

Spider morphological characteristic	Phylogenetic component	Niche conservatism component	Ecological component	Unexplained variation
Habitat
Body size	0.641	0.038	0.003	0.317
Flatness	0.29	0.02	0.001	0.69
Guild
Body size	0.26	0.419	0.012	0.309
Flatness	0.203	0.106	0.002	0.689

These results represent the habitat scale analysis (Fig. 2B). Coefficients of determination in bold type denoting significant p-values (<0.05).
