Fig. 3

Pairwise comparisons of the variances of PGLS values for each diet. d, distance between variances; Z, effect size; p, significance value (significant differences are indicated in bold). Wide solid arrows connect diets that show significant differences, narrow solid arrows connect diets that show marginally significant differences, and narrow dashed arrows connect diets that do not show significant differences between them. Fruits shaded in gray indicate the possibility of being included in the diet despite not being considered in the categorization, as indicated in Table 2
