Figure 2

Measures of foot morphology as a function of size for all species of European Hydromantes. A) Foot sinuosity versus foot length, B) Predicted values of foot sinuosity ( Y ^ ) from species-specific regressions versus foot length, C) Regression scores of foot shape [46] versus log(Centroid Size), D) Predicted values of foot shape ( Y ^ ) from species-specific regressions versus log(Centroid Size). In all panels, symbol size is proportional to specimen size. Species displaying allometric relationships are shown as circles, while species displaying isometric relationships are shown as diamonds. Species are shown in the following colors: H. (S.) ambrosii = violet; H. (S.) flavus = yellow; H. (S.) genei = beige; H. (S.) imperialis = light green; H. (S.) italicus = light gray; H. (S.) sarrabusensis = red; H. (S.) strinatii = salmon; H. (S.) supramontis = blue.
