Abstract: Lay SummaryWe investigated geographical variation in multiple traits in the oriental fire-bellied toad and tested whether local adaptation to predators has affected the observed divergence of these traits. Our field surveys and experiments revealed that mainland and island frogs were distinguishable in morphology and behavior, most likely due to marked differences in predation pressure between locations. Our study therefore shows how differential predation pressure can affect the geographical divergence of multiple traits.
