Introduction There is growing evidence that endocrine body rhythms including the hypothalamic–pituitary–thyroid (HPT) axis are regulated by the circadian timing system, which consists of the master pacemaker located in the hypothalamic

consider some of the molecular mechanisms known to drive LD responses, and their regulation by the circadian clock. Circannual rhythms are also dominant characteristic of the reproductive biology of many tropical species. For instance, even when species

preoptic area (POA; de la Iglesia et al . 1995 ). Transmission of the time-of-day signal from the SCN to CRH- and GnRH-synthesizing neurons is thought to be involved in the entrainment of the circadian rhythm governing the activities of the HPA and HPO
