FIG. 4. Character states for the left and right dorsolateral folds for R in Morphological Change during Rapid Population Expansion Confounds Leopard Frog Identifications in the Southwestern United States

FIG. 4. Character states for the left and right dorsolateral folds for R. berlandieri, uncertain individuals, and R. yavapaiensis. Points along the dark line indicate individuals with the same character state for the left and right dorsolateral folds. See text for description of character states. We have applied a small amount of random noise to the points to enhance visibility.
