Fig. 4

Phylogenetic independent contrasts (PICs) show that short-wave reflectance (blue-ish color) has evolved in correlation with lipid content, but not with other fruit traits. We illustrate here linear regressions with Bonferroni-adjusted p-values for all correlations between color (short wave reflectance) and the five fruit traits used in the phylogenetic PCA: a lipid content, b pulp volume, c endocarp flatness, d moisture content, and e fruit width. Blue ribbons indicate 95% confidence intervals
