Although amphibians are the dominant vertebrate inhabiting playa wetlands during spring and summer in the Southern Great Plains, little is known about their diet and role in playa trophic structure. Because new metamorphs are more numerous than other terrestrial life stages of amphibians, we describe the diets of recently (<2 weeks) metamorphosed Great Plains toad (Bufo cognatus), barred tiger salamander (Ambystoma tigrinum), and New Mexico spadefoot (Spea multiplicata). Cultivation has greatly altered most playa watersheds (>95%); therefore, we also examined this influence on diets of Great Plains toad metamorphs. Diets of all 3 species were dominated by coleopteran taxa, and diversity of prey taxa did not vary among species. Amount of specific prey consumed varied among species, with Great Plains toads preying more on scarab beetles and formicid ants than New Mexico spadefoots and tiger salamanders. New Mexico spadefoot metamorphs consumed more chrysomelid and elaterid beetles than tiger salamanders or Great Plains toads. Given the high numerical abundance of metamorphs, they likely have a strong influence on secondary production in playas. Great Plains toad metamorphs in playas with grassland watersheds had a much more diverse diet than those using playas with cultivated watersheds. Conservation of amphibians in the Southern Great Plains should focus on preserving playas with native grassland watersheds or restoring those with cultivated watersheds.
