Impact of Introduction: In Wellfleet, Lithobates catesbeiana is apparently expanding its population and out-competing the native Green Frog (Lithobates clamitans). Larvae can have a significant impact upon benthic algae, and thus perturb aquatic community structure. Where introduced populations have been studied in the Western U.S., adults consume birds, rodents, frogs, snakes, turtles, lizards, and bats. They are voracious eaters who will also prey on their own young.
The introduced L. catesbeiana out-competes native amphibians in the modified portions of Trinity River, California (Fuller et al. 2011), indicating that habitat modification might aid in the establishment and spread of this species.
