Figure 2. Principal Component Analysis (PCA) plots of the species of the L. nigroviridis group, performed with the residuals of each character regressed on snout-vent length. On the left panels, the individuals are colored according to their species as shown on the legend on the top right corner. Ellipses represent the 95% confidence interval around the centroid for each species. On each axis, the PC is labeled according to its number and the percentage of the total variance that PC explains. On the right, the variable graphs, which illustrate the contribution of each variable to the construction of the axes.
