Fig. 26. Specimen scores representing 10 in A Systematic Review Of Sulawesi Bunomys (Muridae, Murinae) With The Description Of Two New Species

Fig. 26. Specimen scores representing 10 population samples of Bunomys chrysocomus projected onto first and second principal components extracted from principal-components analysis of 16 cranial and two dental log-transformed variables. Upper graph: All variables are represented and scores for four of the five holotypes associated with B. chrysocomus are present. Lower graph: The holotype of chrysocomus is added; because the skull is incomplete, four variables had to be excluded (occipitonasal and postpalatal lengths, zygomatic breadth, and height of braincase could not be measured; fig. 24). Symbols: filled triangles 5 northern peninsula (N 5 10); empty triangles 5 Bumbarujaba (N 5 7); empty circles 5 Sungai Oha Kecil + Sungai Sadaunta (N 5 146); filled circles 5 Danau Lindu + Gunung Kanino (N 5 42); empty squares 5 Gimpu (N 5 3); left-pointing empty triangles 5 Gunung Tambusisi (N 5 6); asterisks 5 Pegunungan Mekongga (N 5 11); empty diamonds 5 Lalolei (N 5 3); filled squares 5 Gunung Balease (N 5 3); star 5 single specimen from Bakubakulu. Arrows and abbreviations identify scores for holotypes: b 5 brevimolaris; c 5 chrysocomus; k 5 koka; n 5 nigellus (empty triangle); r 5 rallus. See table 23 for correlations (loadings) of variables with extracted components and for percent variance.
