Figure 5

Between-group principal component analyses. Bivariate graph derived from PC I and PC II with the regression residuals (Pco-Cs) for pelvis (A), femur (C), and tibia (E). The plots also show the tree topology mapped on the morphospace. Three-dimensional models showing the shape change associated with these axes for the pelvis (B [lateral view]), femur (D [caudal and lateral views]), and tibia (F [caudal and lateral views]). Symbols: blue empty circle, tree root; blue circles, cursorial; green circles, scansorial; orange triangle, terrestrial; black square, arboreal; yellow square, semiaquatic; red circle, semifossorial. See Additional file 4 for interactive models. See Additional file 3: Table S1 for species labels.
