Fig. 55 in A Systematic Review Of Sulawesi Bunomys (Muridae, Murinae) With The Description Of Two New Species

Fig. 55. Specimen scores representing all population samples of Bunomys fratrorum (filled circles; N 5 100), B. andrewsi (empty circles; N 5 98), and B. penitus (filled inverted triangles; N 5 181) projected onto first and second principal components extracted from principal-components analysis of 16 cranial and two dental log-transformed variables. Upper graph: Samples of B. fratrorum are contrasted with all population samples of B. andrewsi. Ellipses outline 95% confidence limits for the cluster centroids. Equations for the regression lines are: B. fratrorum, Y 5 ‾0.406× 0.951 (F 5 34.30, P 5 0.000); B. andrewsi, Y 5 ‾0.407× ‾0.951 (F 5 60.46, P 5 0.000). Lower graph: samples of B. fratrorum are contrasted with all population samples of B. penitus. See table 43 for correlations (loadings) of variables with extracted components and for percent variance explained for both ordinations.
