Abstract:
Circadian rhythms of flashing and glow were recorded simultaneously in Gonyaulax polyedra by determining maximum and minimum light emission at each measured interval of 28 sec. In constant light, the two rhythms in some cases showed different period lengths (τ), the glow rhythm being up to 1 hr shorter than the flashing rhythm. Lower temperatures shortened the τ of the glow rhythm more than that of the flashing rhythm. The amplitude of the flashing rhythm decreased when the temperature was increased from 15°C to 25°C, whereas that of the glow rhythm was increased. These results may indicate that the two rhythms are controlled by two separate oscillators.
