A, B. Three dimensional plots of the D. buzzatii species cluster based on the first three canonical variables (CVs) obtained from 21 CHC components analyzed.A) Plot of the 18 populations/species.Altogether, the first three CVs explained 83% of the variance in the data (CV1 = 48%, CV2 = 20%, and CV3 = 15%) See Additional File 5: Table S2 for details. All Mahalanobis distances between populations were significant (P < 0.0001). Arrows denote the highly divergent D. serido populations. Numbers represent the localities of the eighteen populations used in the CHC analysis (see Table 1 and Figure 1). B) Plot of the 14 populations/species of the D. buzzatii cluster after deleting the four D. serido populations. Altogether, the first three CVs explained 85% of the variance in the data (CV1 = 46%, CV2 = 27%, and CV3 = 12%). See Additional File 6: Table S3 for details.
