Shifts in evolutionary rates of total neck morphology and stochastic character maps of ecological characters. A Evolutionary rates of total neck morphology estimated using BayesTraitsV3 using a variable-rate model and lambda tree transformation, along with significant shifts in the rates of nodes (green pies) and branches (orange pies); pie charts denote the posterior probability of a rate shift occurring at that location. B, C Stochastic character maps of dietary (B) and foraging (C) guild, with rate shifts from A indicated by triangles (node shifts represented in green, branch shifts represented in orange). The trees in A–C all display the same orientation, and so clade names are abbreviated in B and C
