Measures of phenotypic (ρ) and genetic (Γ) divergence are given for both early and late traits separately and for two alternative MANOVA models (see materials and methods for details). In the one-level test, G is compared either to D among populations without correcting for habitats (DP, ρP). In the two-level test, G is compared both to D among populations nested within habitats (DP/H, ρP/H) and to D between habitats and (DH, ρH). When available, the C.I. is given in parentheses. The degrees of freedom (d.f.) of the corresponding matrix estimates are given, and the corresponding within-population G matrix was estimated with d.f. = 244.

A significant difference, i.e., nonoverlapping C.I., or a significant randomization test for habitat effects.
