Non-sinusoidal Waveform in Temperature-Compensated Circadian Oscillations

Adaptive Temperature Compensation in Circadian Oscillations

A temperature independent period and temperature entrainment are two defining features of circadian oscillators. A default model of distributed temperature compensation satisfies these basic facts yet is not easily reconciled with other properties of circadian clocks, such as many mutants with altered but temperature compensated periods. The default model also suggests that the shape of the cir...

Temperature-compensated circadian clock in the pineal of Anolis.

The pineal organ of the lizard Anolis carolinensis can be maintained for up to 10 days in superfused organ culture. During this time it synthesizes and releases melatonin into the medium flowing slowly over it. Collection of timed aliquots of medium and subsequent analysis for melatonin by radioimmunoassay reveal circadian rhythms of melatonin output by the isolated pineal. These rhythms persis...

Circadian oscillations of body temperature in the marmoset, Callithrix jacchus.

The rectal temperature of 8 marmosets was taken regularly throughout a 76 hour period. A pronounced circadian rhythm was detected: body temperature reached a maximum during the light phase and a minimum during the dark phase.

Temperature-compensated chemical reactions.

Circadian rhythms are daily oscillations in behaviors that persist in constant light/dark conditions with periods close to 24 h. A striking feature of these rhythms is that their periods remain fairly constant over a wide range of physiological temperatures, a feature called temperature compensation. Although circadian rhythms have been associated with periodic oscillations in mRNA and protein ...
