Fig. 7 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. 7. Specimen scores representing five population samples of Rubrisciurus rubriventer projected onto the first and second principal components extracted from principal-components analysis. Symbols identifying samples are: filled triangle 5 northeastern peninsula (Rurukan, Temboan; N 5 2); star 5 northern peninsula (Bumbulan, Ile-Ile; N 5 5); filled circle 5 north-central region1 (Sungai Oha Kecil, Sungai Miu, Sungai Sadaunta, Tomado, Gunung Kanino, Kulawi; N 5 18); asterisk 5 north-region 2 (Kuala Navusu, Sungai Tolewonu; N 5 19); filled square 5 southeastern peninsula (Wawo, Masembo, Tanke Salokko; N 5 5). The score located farthest to the right in the ordination represents AMNH 224623, an especially large adult from Sungai Oha Kecil. Delicate arrows identify scores of four specimens from Gunung Kanino collected in lower montane forest, 1274–1418 m. Lettered arrows indicate scores for the specimen from Wawo (w) collected on the coastal plain at 50 m in tropical lowland evergreen rain forest and the squirrel from the inland mountains at Tanke Salokko (t) at 1400 m taken in lower montane forest; both places are in the southeastern peninsula of Sulawesi. See table 9 for correlations and percent variance.
