Pairwise comparisons (using total shape) indicated browsers can be distinguished from mixed feeders and grazers with borderline significance ( P = 0.05, Z = 1.7 for both), and all other pairwise comparisons were nonsignificant.
7 ), shape and diet were of borderline significance among central species (pgls ANOVA, shape ~ diet, P = 0.06, Z = 1.6), with pairwise comparisons of means distinguishing browsing from mixed-feeding taxa ( P = 0.006, Z = 2.4), but significantly different among peripheral species ( P = 0.01, Z = 2.3), distinguishing browsers from grazers and mixed feeders ( P = 0.003, Z = 2.98, and P = 0.02, Z = 2.15, respectively).
3 ) were highly significant (ols ANOVA, shape~subfamily, shape~tribe, Table 1 ).
