Fig. 8 in A practical, step-by-step, guide to taxonomic comparisons using Procrustes geometric morphometrics and user-friendly software (part B): group comparisons

Fig. 8. PC1–PC2 summary scatterplot of species-specific allometric predictions (66% of total allometric shape). As an example, the opposite extremes of the allometric trajectories of yellow-bellied marmots (fla) and woodchucks (mon) are shown (magnified five times) using wireframes and thin plate spline deformation grids, drawn in TPSRelw by 'warping' variation along the regression lines in the PC1–PC2 subspace.
