Many seasonal breeding animals can estimate the day length (photoperiod) and prepare for breeding in the optimal season. The Japanese quail (Coturnix japonica) is an excellent model for studying photoperiodism because of its rapid and dramatic res...
A new circadian variant was isolated by screening the intercross offspring of wild-caught mice (Mus musculus castaneus). This variant was characterized by an initial maintenance of damped oscillations and subsequent loss of rhythmicity after being...
Many animals that breed seasonally measure the day length (photoperiod) and use these measurements as predictive information to prepare themselves for annual breeding. For several decades, thyroid hormones have been known to be involved in this bi...

Molecular mechanisms regulating animal seasonal breeding in response to changing photoperiod are not well understood. Rapid induction of gene expression of thyroid- hormone- activating enzyme ( type 2 deiodinase, DIO2) in the mediobasal hypothalam...
In order to adapt to seasonal changes, animals exhibit robust changes in their reproductive status, body weight, and molt. However, the molecular mechanisms regulating such seasonal changes in physiology and behavior are not fully understood. Here...
