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.
