  • A major controversy of sexual selection theory is whether sexually dimorphic characters used in display by males have arisen through male–male competition, female choice, or both1–4. Here I describe the chorusing behaviour of male natterjack toads (Bufo calamita) and show that the pitch of the advertisement call is an important determinant of male mating success. Playback experiments using synthetic calls show that when males compete for calling sites they use call pitch to assess the body size… CONTINUE READING
