Figure 2 Shape principal component analysis (shape PCA) of 273 females of Tetrix bipunctata and kraussiA analysis including 17 variables, scatterplot of first against second shape PC; in parentheses the variance explained by each shape PC BPCA ratio spectrum for first shape PC CPCA ratio spectrum for second shape PC. Horizontal bars in the ratio spectra represent 68% bootstrap confidence intervals, based on 1000 replicates; only the most important characters are indicated in ratio spectra.
