摘要: Circadian clocks with characteristic period (tau) can be entrained to light/dark (LD) cycles by means of(i) phase shifts which are due D/L "dawn" and/or L/D "dusk" transitions, (ii) changes associated long-term light exposure, or (iii) combinations of the above possibilities. Based on stability analysis a model circadian clock it was predicted that nocturnal burrowing mammals would benefit less from responses than their diurnal counterparts. The further maximal is reached when slightly both its and in response stimuli. Analyses empirical curve (PRC) (tauRC) some revealed PRCs have similar waveform while tauRCs smaller amplitude those mammals. shape tauRC also age increasing strength During erratic fluctuations intensity under different weather conditions, entrainment appears achieved an interplay between
