✦ Synopsis
In the strictly dark-active C. problematicus and the mainly dark-active C. cancellatus the Aschoff-rule is effective only between 0 and 2 (4) Lux. The circadian rule is violated by these species because no correlation exists between the quotient α/ϱ and the period length τ. Spontaneous changes of α/ϱ are not associated with changes of τ in the sense of the circadian rule. τ and light intensity are correlated with certain regularity, but no correlation could be found between light intensity and quantity of activity.
