Abstract

The function of light in the reproductive cycle in amphibians has not been extensively studied. However, Farner (1965) feels that the small amount of experimental evidence suggests that photoperiod may play a role in the testicular cycle of Rana esculenta. The purpose of this paper is to study the effect of light on the gonads and the gonadotropic hormone forming cells of the adenohypophysis in the newt Taricha granulosa granulosa.
