The circadian system constrains an organism's palette of behaviors to portions of the solar
day appropriate to its ecological niche. The central light-entrained clock in the …

Clock gene oscillations are necessary for a successful pregnancy and parturition, but little is
known about their function during lactation, a period demanding from the mother multiple …

Mother rabbits nurse their young once a day with circadian periodicity. Nursing bouts are
brief (ca. 3 min) and occur inside the maternal burrow. Despite this limited contact mother …

Rabbit pups ingest food, in this case milk, once a day with circadian periodicity and are a
natural model of food anticipatory activity. During nursing, several sensory systems receive …

Rats exposed to timed restricted meals develop anticipation of food. They increase their
activity levels in the hours preceding food access; this has been described as food …

Nursing in the rabbit is under circadian control, and pups have a daily anticipatory
behavioral arousal synchronized to this unique event, but it is not known which signal is the …

Rabbits use a variety of olfactory signals to transmit information related with reproduction.
Such cues are produced in skin glands (submandibular, anal, Harder's, lachrymal, preputial) …
