Fig. 89. Specimen scores representing Bunomys karokophilus (empty triangles; N 5 17) from Sungai Sadaunta and the Danau Lindu Valley and all population samples of B. fratrorum (filled circles; N 5 100) projected onto first and second principal components extracted from principal-components analysis (upper graph), and on first and second canonical variates derived from discriminant-function analysis (lower graph) of 16 cranial and two dental log-transformed variables. Ellipses outline 95% confidence limits for cluster centroids. Equations for the regression lines in the upper graph are: B. karokophilus, Y 5 0.215 × 0.096 (F 5 2.12, P 5 0.166); B. fratrorum, Y 5 0.130× ‾0.012 (F 5 2.91, P 5 0.091). See table 67 for correlations (loadings) of variables with extracted components and canonical variates and for percent variance explained for both ordinations.
