FIG. 5 in A New Green Salamander in the Southern Appalachians: Evolutionary History of Aneides aeneus and Implications for Management and Conservation with the Description of a Cryptic Microendemic Species

FIG. 5. Results of Principal Components Analysis (PCA) and Linear Discriminant Analysis (LDA) using 14 morphological characters. For both analyses, data were normalized where possible and necessary (longest toe, 5th toe log-transformed; adpressed limbs converted to absolute value and then log-transformed). (A) PCA with points and normal data ellipses colored by species. (B) Density plot of prediction accuracy by LDA across 1,000 permutations of samples for the training and prediction sets.
