FIGURE 5. Biplot of the PCA performed on six mensural characters (SVL, HL, HW, AGD, Forelimb and Hindlimb). Axes show the first two principal components (i.e., PC1 and PC2) and their percentage of explained variation. Large, coloured ovals denote the 90% concentration ellipses for each taxonomic group proposed by Storr (1991a). Small points denote PC scores of individuals, whereas large points denote group centroids. Variables are denoted by arrows, the direction and length of which indicates their degree of contribution to each axis. Each variable is coloured according to its percentage contribution to its associated PC.
