Scatterplots of first three shape Principal Components with superimposed phylogenetic tree and diet variables. (A) The phylogeny tips (species mean shapes) are depicted as spheres, coloured according to major dietary preferences (green - insectivores, yellow - carnivores, red - frugivores, purple - sanguivores, blue - nectarivores). Connecting lines determined by phylogeny branches, where nodes correspond to estimated ancestral shapes. The tree root shape is depicted as a black sphere. Branch colours correspond to estimated ancestral diets. (B) Scatterplot of first three shape PCs with associated diet PCs. Diet PC vectors directions based on partial correlations from the multivariate PGLS regression. Names in parentheses after diet PCs indicate the main dietary item associated with that PC direction.
