We then performed a phylogenetic PCA, on all morphological variables, with phytools (Revell, 2012). Phylogenetic ANOVAs and phylogenetic PCA were also ran on the size‐corrected data set (Appendix S2). We also used PCA to reduce the dimensionality of the environmental data set. We performed ANOVAs and post hoc pairwise comparisons using Dunnett’s tests as well
