regulation of prolactin secretion and consequent pelage moult cycle in the Siberian hamster and Soay sheep Typically for most photoperiodic mammals, long days (LD) activate prolactin release and a summer physiology, while short days (SD)

We demonstrate that the phases of peak expression of the clock genes Cryptochrome1 (Cry1), Period1 (Per1), and RevErb respond acutely to altered melatonin se-cretion after a switch from short to long days
- Mammalian circannual pacemakers - biosciproceedings. org
Organisms utilise two interacting timing mechanisms to regulate long-term cycles in reproduc-tion, hibernation, moult and a plethora of seasonal characteristics (Figure 1) The principle mechanism is circannual rhythm generation where the long-term transitions in physiology are controlled endogenously by some form of interval timer or pacemaker
- Seasonality of prolactin in birds and mammals
We present an overview of seasonal variations of prolactin secretion across a range of model species, as well as our understanding of how seasonal prolactin variability is regulated
