Figure 3. Pairwise comparisons between mean shapes of each clade (Antechinus stuartii south vs. A. stuartii north, P = 0.003; A. stuartii north vs. A. subtropicus, P = 0.003; A. stuartii south vs. A. subtropicus, P = 0.003; all p-values were adjusted with following the Bonferroni method). The 3D images are the specimen closest to the overall mean warped correspondingly to the mean shapes of each clade. Tukey post-hoc analyses of linear measurements after size correction were performed; significance levels (*P <0.05, **P <0.01, ***P <0.001) are shown in the boxplots. For each comparison, we have labelled the best differentiator diagnostic; i.e. the size of the major palatine foramina (mapf) for differentiating A. stuartii south and A. stuartii north, the size of the incisive foramina (inf) for differentiating A. stuartii north and A. subtropicus, and the interpalatal distance (intp) for differentiating between the three clades. Clades are consistently labelled as per Figure 1.
