Fig. 1

General structure of morphological variation in each species as visualized through principal components analysis of all individuals (light grey) or population means (dark grey) based on the multivariate set of biometric and scalation traits, and geometric morphometric data used to quantify head shape. Top: percentage of variance explained by each principal component. Bottom: correlations between the first PC and raw variables for each set of traits. For head shape as quantified through geometric morphometrics, deformation grids illustrate shape variation from the minimum to the maximum extreme of the first PC.
