Fig. 87 in A Systematic Review Of Sulawesi Bunomys (Muridae, Murinae) With The Description Of Two New Species
Fig. 87. Occlusal views of right maxillary molar rows in Bunomys karokophilus. Left: a very young adult (AMNH 257190; CLM1–3 5 6.8 mm) showing slight wear and no cusp t1 on the third molar (arrow). Middle: wear typical of adults; a small cusp t1 (arrow) is present on the third molar in this specimen (AMNH 223072; CLM1–3 5 7.0 mm). Right: an old adult in which most cusp rows are basined; the small cusp t1 (arrow) on the third molar is recognizable only by a bulge forming the anterolingual border of the tooth (AMNH 225027; CLM1–3 5 6.8 mm). The second molar lacks a cusp t3 (as shown in the middle image) in one-third of the sample and is less frequently present on the third molar (22% of the sample); see table 10.

Fig. 54. Lateral views of the cranium and dentary of the same specimens presented in figures 52 and 53. Upper pair: B. fratrorum and B. andrewsi. Lower image: B. penitus. ×2.
Fig. 90 in A Systematic Review Of Sulawesi Bunomys (Muridae, Murinae) With The Description Of Two New Species
Fig. 90. Specimen scores representing samples of Bunomys karokophilus (empty triangles) from Sungai Sadaunta (823–1006 m), Tomado (1000 m), and Sungai Tokararu (1150 m), and samples of Bunomys chrysocomus (filled triangles) from Sungai Sadaunta (823–960 m), Tomado (1000 m), and Sungai Tokararu (1150 m) projected onto first and second principal components extracted from principal-components analysis. Ellipses outline 95% confidence limits for each cluster centroid in both ordinations. Upper graph: derived from a covariance matrix of log-transformed values for lengths of head and body, tail, hind foot, and ear (N 5 22 for B. karokophilus; N 5 71 for B. chrysocomus). Lower graph: based on a covariance matrix of log-transformed values for 16 cranial and 2 dental variables (N 5 17 for B. karokophilus; N 5 77 for B. chrysocomus). Equations for the regression lines are: B. karokophilus, Y 5 0.867× ‾2.254 (F 5 9.02, P 5 0.009); B. chrysocomus, Y 5 0.873× 0.500 (F 5 28.52, P 5 0.000). See table 69 for correlations (loadings) of variables with extracted components and for percent variance explained for both ordinations. The results illustrated here focus on samples of each species collected at Tomado, Sungai Tokararu, and within the same elevational range along the Sungai Sadaunta. The pattern of scores in the lower scatter plot, and degree of significance of the Y-intercepts of the regression lines and their slopes, is closely similar to the pattern derived from comparing the sample of B. karokophilus with all samples of B. chrysocomus from my transect (N 5 186) and all 10 population samples (N 5 232; table 2) of that species (neither is illustrated).

Fig. 75 in A Systematic Review Of Sulawesi Bunomys (Muridae, Murinae) With The Description Of Two New Species
Fig. 75. Occlusal views of right maxillary (A, B) and mandibular (C) molar rows illustrating variation in particular cusps and cusplets in the sample of Bunomys penitus. On the first upper molar in 65 of 215 specimens surveyed (30%), there is a large labial cusplet (short arrows) that is either separate from the adjacent cusp t6 (as in A) or partially merged (but still evident) with the larger cusp t6 (shown in B); contrast this pattern with the usual configuration shown in figure 74 where a labial cusp is not present. Cusp t3 (long and thin arrows) occurs (B) on the second upper molar in 62% of the sample surveyed, but is absent from the remainder of the sample (as in fig.74A), and is part of the third molar (B) in only 5% of the sample (table 10). All specimens surveyed exhibit a small, moderately large, or huge posterior labial cusplet (stubby arrow in C) on the first lower molar (as exhibited by the lower molars in figs.74 and 75); an anterior labial cusplet is rare (table 11). The second lower molars of nearly all specimens in the sample also bear posterior labial cusplets (stubby arrow in C) with a comparable range in size. The second lower molar in C is without an anterolabial cusp, which is absent in about half the sample (45%) and absent from the third molar in all specimens surveyed (table 11). A, AMNH 223818 (CLM1–3 5 7.7 mm); B, AMNH 223846 (CLM1–3 5 7.8 mm); C, AMNH 223844 (clm1–3 5 7.2 mm).
Fig. 49 in A Systematic Review Of Sulawesi Bunomys (Muridae, Murinae) With The Description Of Two New Species
Fig. 49. Upper graph: Specimen scores representing all population samples of Bunomys chrysocomus (filled triangles; N 5 232), and the samples of B. coelestis (empty diamonds; N 5 18), B. prolatus (asterisks; N 5 8), and B. torajae (empty squares; N 5 2) projected onto first and second canonical variates extracted from discriminant-function analysis of 16 cranial and two dental log-transformed variables. See table 39 for correlations (loadings) of variables with extracted canonical variates and for percent variance explained. Lower diagram: Phenetic relationships among 13 population samples representing Bunomys chrysocomus, B. coelestis, B. prolatus, and B. torajae generated from UPGMA clustering of squared Mahalanobis distances among group centroids as derived from discriminant-function analysis.
Fig. 50 in A Systematic Review Of Sulawesi Bunomys (Muridae, Murinae) With The Description Of Two New Species
Fig. 50. Collection localities for samples of Bunomys fratrorum, B. andrewsi, and B. karokophilus, n. sp. Numbers key to localities described in the gazetteer. The inset map (small rectangle above and in full on opposite page) contains some of the localities where B. andrewsi was obtained (7–12) and all the places where we trapped B. karokophilus, n. sp., along Sungai Sadaunta, the area around Danau Lindu, and near Sungai Tokararu (localities 1–10). The dashed contour line at 1300 m marks the approximate boundary between tropical lowland evergreen rain forest and tropical lower montane forest. The filled circle (highlighted by arrow) on that dashed line is the lowest spot (1285 m in lower montane forest) where we encountered B. penitus, a species trapped at higher elevations all the way to the summit of Gunung Nokilalaki (see the map in fig. 51, and discussion in the account of B. karokophilus, n. sp., where that species and B. penitus are compared).
Fig. 51 in A Systematic Review Of Sulawesi Bunomys (Muridae, Murinae) With The Description Of Two New Species
Fig. 51. Collection localities for samples of Bunomys penitus. Numbers key to localities described in the gazetteer. The inset map (small rectangle above and in full on opposite page) records collection sites on Gunung Kanino and Gunung Nokilalaki in lower and upper montane forest. The dashed contour line at 1300 m marks the approximate boundary between tropical lowland evergreen rain forest and lower montane forest. The filled triangle (highlighted by arrow) is the highest place (1150 m in lowland tropical evergreen rain forest) where we trapped B. karokophilus, n. sp. (see discussion in the account of B. karokophilus, n. sp., where it and B. penitus are compared).

Upper graph: B. torajae (N 5 3) contrasted with B. andrewsi (N 5 40; filled circles 5 scores for six specimens from Gunung Gandangdewata). Lower graph: the same specimens of B. torajae compared with B. penitus (N 5 170; empty inverted triangles 5 scores of four specimens from Gunung Gandangdewata). See table 38 for correlations (loadings) of variables with extracted components and for percent variance explained for both ordinations.
Fig. 46 in A Systematic Review Of Sulawesi Bunomys (Muridae, Murinae) With The Description Of Two New Species
Fig. 46. Specimen scores representing samples of Bunomys torajae (empty squares) and B. chrysocomus (filled triangles) projected onto first and second principal components extracted from principalcomponents analysis. Upper graph: derived from log-transformed values for lengths of head and body, tail, hind foot, and ear (N 5 3 for B. torajae; N 5 71 for B. chrysocomus from Sungai Sadaunta, Tomado, and Sungai Tokararu). Lower graph: based on log-transformed values for 14 cranial and 2 dental variables (N 5 3 B. torajae; N 5 232 for all 10 population samples of B. chrysocomus). See table 36 for correlations (loadings) of variables with extracted components and for percent variance explained for both ordinations.
Fig. 42 in A Systematic Review Of Sulawesi Bunomys (Muridae, Murinae) With The Description Of Two New Species
Fig. 42. Upper graph: Specimen scores representing the sample of Bunomys coelestis (empty diamonds; N 5 18) and all population samples of B. chrysocomus (filled triangles; N 5 232) projected onto first and second principal components extracted from principal-components analysis of 16 cranial and two dental log-transformed variables. Arrows point to scores for holotypes of Bunomys coelestis (empty diamond) and Bunomys caelestis koka (empty triangle). Ellipses outline 95% confidence limits for cluster centroids. Equations for the regression lines are: B. chrysocomus, Y 5 ‾0.279× ‾0.189 (F 5 24.10, P 5, 0.000); B. coelestis, Y 5 ‾0.479× +2.746 (F 5 4.74, P 5 0.045). Lower graph: Scores for the same samples of B. coelestis (empty diamonds) and B. chrysocomus (empty triangles) projected onto first and second canonical variates extracted from discriminant-function analysis of the 16 cranial and two dental log-transformed variables. Included are scores for the holotype of Bunomys coelestis (filled diamond marked by arrow) and sample of Bunomys caelestis koka (filled triangle, arrow identifies holotype). Scores for the specimens of koka, including the holotype, mostly nest within the polygon bounding scores for B. chrysocomus and nowhere near the cluster marking B. coelestis. See table 32 for correlations (loadings) of variables with extracted components or canonical variates and for percent variance explained for both ordinations.
Fig. 31. Tropical lowland evergreen rain forest along the Sungai Sadaunta, 700 m in A Systematic Review Of Sulawesi Bunomys (Muridae, Murinae) With The Description Of Two New Species
Fig. 31. Tropical lowland evergreen rain forest along the Sungai Sadaunta, 700 m (in 1976). Examples of Bunomys chrysocomus were caught amid the rocks in the foreground, deep within the forest, and occasionally on trunks and branches spanning the stream. Similar dense streamside forest and bridging trunks and limbs from old treefalls characterize much of the habitat along the Sungai Sadaunta where B. chrysocomus as well as B. karokophilus, n. sp., were encountered (see Natural History in account of B. chrysocomus).
