Neural and behavioral responses to reproductive signals in male chorus frogs

Species recognition and courtship behaviors are powerful drivers of speciation. Here, we investigate the neural and behavioral signatures of species recognition in Upland chorus frogs (Pseudacris feriarum). Populations of this species that are sympatric with congener/s (e.g., P. nigrita) have evolved divergent male mating calls and enhanced acoustic discrimination by females due to costly interspecific hybridization. Herein, we examined evoked neural activity and behaviors in male P. feriarum in
