Fig. 43 in Systematic Review of Endemic Sulawesi Squirrels (Rodentia, Sciuridae), with Descriptions of New Species of Associated Sucking Lice (Insecta, Anoplura), and Phylogenetic and Zoogeographic Assessments of Sciurid Lice
Fig. 43. An adult male Hyosciurus ileile caught at 155 m above camp on the Sungai Tolewonu in tropical lowland evergreen rain forest. The squirrel was trapped on a large decaying trunk (2 ft in diameter) forming a bridge 15 m long straddling the river, one end on a narrow bank at base of steep hillside, the other resting on river terrace 3 ft above the water surface; caught about 10:30 a.m. See account of this species for description of behavior and diet. See table 2 for range of ambient temperatures recorded during the trapping duration at the Sungai Tolewonu. Photographed in 1976.

Fig. 32 in Systematic Review of Endemic Sulawesi Squirrels (Rodentia, Sciuridae), with Descriptions of New Species of Associated Sucking Lice (Insecta, Anoplura), and Phylogenetic and Zoogeographic Assessments of Sciurid Lice
Fig. 32. Specimen scores representing seven population samples of Prosciurillus murinus projected onto the first and second principal components extracted from principal-components analysis. Symbols identifying samples are: filled circle 5 northeastern peninsula (Teteamoet, Gunung Klabat, Temboan; N 5 7); X 5 Pulau Lembeh (N 5 4); cross 5 northern peninsula east of the Minahasa region (Sungai Paleleh, Bumbulan, Ile-Ile; N 5 9); filled upright triangle 5 Gunung Lehio (N 5 1); filled inverted triangle 5 north-central 1 (Sungai Oha Kecil, Sungai Miu, Sungai Sadaunta, Tomado, Kulawi; N 5 18); filled leftpointing triangle 5 Rano Rano (N 5 2); filled right-pointing triangle 5 north-central region 2 (Pinedapa, Kuala Navusu, Sungai Tolewonu; N 5 16). Heavy arrows identify holotypes: e, evidens; n, necopinus. Delicate arrows identify scores representing four AMNH specimens from Bumbulan, which were collected by J. J. Menden between October 10 and 25, 1939. Two others from Menden's sample, collected on October 24, 1939, are in MZB and Sody (1949: 77) had designated one of these as the holotype of ''Sciurillus murinus griseus'' (the holotype is currently stored in RMNH). Musser determined that the two MZB specimens were inseparable in pelage coloration and general external and cranial morphology from the AMNH series, but did not measure them. See table 40 for correlations and percent variance.

Fig. 27 in Systematic Review of Endemic Sulawesi Squirrels (Rodentia, Sciuridae), with Descriptions of New Species of Associated Sucking Lice (Insecta, Anoplura), and Phylogenetic and Zoogeographic Assessments of Sciurid Lice
Fig. 27. Habitat of Prosciurillus topapuensis in lower montane rain forest on Gunung Kanino, 1440 m. The large, darker tree in the center of the photograph is the oak Lithocarpus glutinosus. Prosciurillus murinus and Rubrisciurus rubriventer occupy this forest as does the ground squirrel Hyosciurus ileile. This elevation is close to the upper altitudinal limits of R. rubriventer and H. ileile. See table 2 for the range of ambient temperatures recorded during the sampling period. Photographed in 1975.
Fig. 26 in Systematic Review of Endemic Sulawesi Squirrels (Rodentia, Sciuridae), with Descriptions of New Species of Associated Sucking Lice (Insecta, Anoplura), and Phylogenetic and Zoogeographic Assessments of Sciurid Lice
Fig. 26. Specimen scores representing six population samples of Prosciurillus topapuensis projected onto the first and second principal components extracted from principal-components analysis. Symbols identifying samples are: filled circle 5 Rano Rano (N 5 11); x 5 Besoa-Lindu trail (N 5 5); cross 5 Gunung Lehio (N 5 9); filled upright triangle 5 Gunung Kanino (N 5 5); filled inverted triangle 5 Sungai Miu and Sungai Sadaunta (N 5 9); filled left-pointing triangle 5 Pegunungan Latimojong (N 5 11). A: All cranial and dental variables are represented, but holotypes of topapuensis and hirsutus are excluded. See table 29 for correlations and percent variance. B: Includes the holotypes of topapuensis (''t'' and filled square) and hirsutus (''h'' and filled right-pointing triangle) but because these specimens are damaged only 11 cranial and dental variables could be employed. See table 30 for correlations and percent variance.
Fig. 28 in Systematic Review of Endemic Sulawesi Squirrels (Rodentia, Sciuridae), with Descriptions of New Species of Associated Sucking Lice (Insecta, Anoplura), and Phylogenetic and Zoogeographic Assessments of Sciurid Lice
Fig. 28. Collection localities for samples of Prosciurillus rosenbergii in the Sangihe Archipelago (Kepulauan Sangihe) north of mainland Sulawesi's northeastern tip. Samples come from Pulau Sangihe, Pulau Siau, and Pulau Tahulandang and the nearby Pulau Ruang. Prosciurillus rosenbergii is the only squirrel ever collected in this group of islands and occurs nowhere else. To the south, off the northeastern tip of Sulawesi's northern peninsula, P. murinus, which is found throughout the mainland, has been collected on Pulau Talisei and Pulau Lembeh, and P. leucomus, ranging over the northern peninsula, is recorded from P. Lembeh (see gazetteers for these two species).
Fig. 24 in Systematic Review of Endemic Sulawesi Squirrels (Rodentia, Sciuridae), with Descriptions of New Species of Associated Sucking Lice (Insecta, Anoplura), and Phylogenetic and Zoogeographic Assessments of Sciurid Lice
Fig. 24. Specimen scores representing population samples of Prosciurillus topapuensis from the central core of the island (empty triangle, N 5 50) and P. leucomus from the northern peninsula (filled diamond, N 5 26) projected onto the first and second principal-components extracted from principal-components analysis. The ellipses outline 95% confidence limits for the specimen scores forming each cluster. Equations for the regression lines are: P. leucomus, Y 5 0.621X20.120 (F 5 22.07, P 5,0.01); P. topapuensis, Y 5 0.222X+0.038 (F 5 9.25, P 5,0.01). The Y-intercepts of each regression line of the second principal component on the first component are significantly different (20.120 versus +0.038; F 5 28.31, P 5,0.001). See table 27 for correlations and percent variance.

Fig. 23. Hillside forest near Kuala Navusu, 60 m in Systematic Review of Endemic Sulawesi Squirrels (Rodentia, Sciuridae), with Descriptions of New Species of Associated Sucking Lice (Insecta, Anoplura), and Phylogenetic and Zoogeographic Assessments of Sciurid Lice
Fig. 23. Hillside forest near Kuala Navusu, 60 m. Aminudi is touching an Artocarpus sericarpus, one of the breadfruit species that is scattered through the forest on streamside terraces and lower margins of hillsides. The forest on hills tends to be shorter than the tall forest on the flats. The palm in the center of the photograph, Licuala rumphii, is common in the understory. Examples of Prosciurillus alstoni, P. murinus, and Rubrisciurus rubriventer were trapped here. Photographed in 1975.
