Circadian Rhythms: The Basis for Information Processing in Eukaryotes during Adaptation to Seasonal Changes in Photo- and Thermoperiods

  • Edgar Wagner
Part of the NATO Advanced Science Institutes Series book series (NSSA, volume 68)


Growth and differentiation of most living systems is tightly coupled to seasonal changes in environmental factors like light and temperature. The multiplicity of organismic responses to light and temperature signals from the environment is generally treated in plant and animal physiology under the headings of photo- and thermoperiodism. Both groups of phenomena reveal a rhythmic change in sensitivity which is endogenous in character and reflects an endogenous rhythm in metabolic activity. This sensitivity change has a period length of about 24 hr and is hence called circadian.
