Abstract

The maintains a period of approximately 24 h across various physiological temperatures.

  • Circadian clocks help organisms synchronize their physiological and behavioral processes with the day-night cycle.
  • allows the circadian clock to function consistently despite variations in temperature.
  • Most play a role in maintaining the circadian period length across different temperatures.
  • Active degradation of specific core clock proteins occurs at lower temperatures to support temperature compensation.
  • Comparative analysis of molecular mechanisms in various organisms could reveal design principles for temperature compensation in circadian clocks.
