Abstract

Seasonal changes in day length are used by plants and animals to synchronize annual rhythms in reproduction, physiology, and behavior to the environment. Increasing day length during spring causes sudden changes in the mammalian reproductive system once the critical photoperiod is reached. The molecular mechanism behind this switch is now quickly being elucidated.
