FIG. 1 in Morphological Change during Rapid Population Expansion Confounds Leopard Frog Identifications in the Southwestern United States

FIG. 1. Types of dorsolateral folds observed in Rana berlandieri and Rana yavapaiensis. These representations depict the right dorsolateral folds. The color of the medially inset, posterior folds (states 1–6) indicate similarity of the tissue to the primary dorsolateral folds (see text for more information). Black depicts posterior folds that are similar in appearance to the primary fold, and lighter shades of gray indicate skin features that are less pronounced than the raised, glandular tissue of the primary folds. State 1 is typical of R. berlandieri across its native range, and state 5 is typical of R. yavapaiensis. Modeled after Pace (1974: fig. 23).
