摘要:

Activity‐rhythm data from four species of semiterrestrial, intertidal crabs collected in Woods Hole, Massachusetts, USA, and Dunedin, New Zealand were investigated using a battery of sensitive digital signal analysis techniques. The animals were tested in a variety of constant lighting regimens, constant darkness, and at a variety of temperatures. In all species a small number of animals showed ultradian rhythms not attributable to either circatidal or circalunidian oscillations.
