Male-male competition and female choice are differentially affected by male call acoustics in the serrate-legged small treefrog Kurixalus odontotarsus

摘要

BackgroundThe evolution of exaggerated vocal signals in anuran species is an important topic. Males and females have both evolved the ability to discriminate communication sounds. However, the nature of sexual dimorphism in cognition and sensory discrimination and in the evolution and limitation of sexual signal exaggeration remain relatively unexplored.
