Hormonal Influences on Calling and Reproductive Behavior in Anurans

  • Hans-Joachim Obert


All the Central European anurans have an annual reproductive cycle; calling, mating and egg-laying occur during a period beginning in the spring or early summer. Examination of the time course of this reproductive behavior has shown, however, that there are two distinct groups of anurans, which for the present I shall simply term Type I and Type II. In the following discussion I shall use mating-call production by male anurans as an indicator of the presence of reproductive activity.
