FIGURE 2 in A new species of the rodent genus Hylomyscus from Angola, with a distributional summary of the H. anselli species group (Muridae: Murinae: Praomyini)

FIGURE 2. Three scatterplots depicting results of principal component (PC) analyses of 16 log-transformed craniodental variables as measured on 175 intact crania representing the Hylomyscus anselli species group. A) Projection of individual scores onto components I and II extracted from ordination of specimens representing H. anselli (N = 15), H. arcimontensis (N = 147), and the Angolan sample (N = 13). B) Projection of specimen scores onto components I and III extracted from the same ordination as performed in plot A. C) Projection of individual scores onto the first two components extracted from ordination of specimens representing H. anselli (N = 15) and the Angolan sample (N = 13); major axes of the species constellations and regression statistics are indicated; the Y intercepts differ significantly (F = 8.23, P = 0.009), but not their slopes (F = 0.38, P = 0.546) (see text for discussion). For scatterplots A and B, see Table 2 for variable correlations and variance explained; for scatterplot C, see Table 4; variable abbreviations are given in the Materials and Methods. The half-filled circles in all three plots indicate the scores of the three Zambian specimens from the type series of anselli Bishop (1979)
