ultradian rhythm
ultradian rhythm A biological rhythm whose periodicity is greater than a day. For example, the body temperature of hibernating animals often shows periodic transient increases corresponding to brief periods of arousal. Also, the reproductive behaviour of many animals follows a circalunar rhythm linked to the 29.5-day lunar cycle. Compare circadian rhythm; infradian rhythm. See biorhythm.
