PC plots of shape variation. PCs are the first two eigenvectors of Procrustes residuals projected into a space tangent to shape space. The relative amount of shape variation explained by PC is shown. Individual shapes are shown as well as convex hulls. Transformation grids (scaled × 2) are shown to facilitate and understand shape change among groups. These shapes correspond to mean values, shown as bolder symbols.
