Figure 3 in A new species of the Liolaemus nigroviridis group from the Andes of Central Chile (Iguania: Liolaemidae)

Figure 3. Principal Component Analysis (PCA) plots of the species of the L. nigroviridis group, performed with the snout-vent length as a variable. On the left panels, the individuals are colored according to their species as shown on the legend on the top left 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.

Figure 1. Phylogenetic relationships of the species of the L. nigroviridis complex group, modified from Torres-Pérez et al. (2017), based on the mitochondrial gene cytochrome b, including the bootstrap values for maximum likelihood, the posterior probabilities for Bayesian inference and the number of haplotypes used for each terminal taxon. Liolaemus fuscus is added as the basal species of the group, following Schulte and Moreno-Roark (2010), Troncoso-Palacios et al. (2015) and Esquerré et al. (2022). Specific name L. nigroviridis is used only for the clade that contains the samples from near the type locality. The candidate species Liolaemus sp. Arpa is in red. Male dorsal pattern is compared.
