Summary
-
1.
The rhythm of locomotor activity in the amphipodTalorchestia quoyana has been monitored in populations and individual animals for up to 105 days.
-
2.
Control of the rhythm is dominated by a light sensitive circadian clock.
-
3.
A circatidal clock inhibits activity at projected times of high tide on the beach of collection.
-
4.
The circatidal clock can be entrained by 2 hr pulses of vibration.
-
5.
In long term records of individual activity, there is evidence of a semi-monthly rhythm in total amount of activity. Minimum activity is correlated with spring tides.
-
6.
Various models for the combined activity of the two clocks are discussed.
