FIGURE 4. Linear discriminant analysis of 142 samples from the four species of Shovel-nosed Salamanders (a), based on 17 measurements taken from vouchered specimens (Appendix S1), with a boxplot for Axilla-Groin length (AG; b) and Snout-Gular Length (SG; c) scaled by size for each species, selected from the heaviest loadings of the 16 variables indicated on a relative scale as grey rays in (a). Non-overlapping notches indicate significant median differences.
