Figure 5. A in Integrative taxonomy using historical specimens provides evidence for a single species of bushbuck, Tragelaphus scriptus (Mammalia: Bovidae)

Figure 5. A, plot of all specimens along the first two principal components (PCs) of shape. B, cranial outlines transformed via thin-plate spline from the mean shape to the extremes of PCs 1 and 2. Note the separation of subclades along PC1, which largely reflects sexual dimorphism and size allometry (see Fig. 3). The key is the same as that shown in Figure 1; labels refer to specimens in Table 1.
