In temperate zones, photoperiod changes dramatically over the course of the year, so organisms have evolved mechanisms allowing anticipation of these environmental changes. The information about changes in duration of daylight is conveyed to the organism via neuroendocrine pathways. These pathways involve photoperiodic modulation of rhythmic production of the pineal hormone melatonin which is under control of the circadian system. This chapter will consider the role of the central circadian clock located in the suprachiasmatic nuclei in the adaptation to the photoperiodic changes, focusing on how photoperiod modulates circadian clock mechanisms at the molecular level.
