原始语种摘要: The process of larval release in field collected ovigerous Carcinus maenas was monitored in the laboratory using a time-lapse video recorder. Under constant light (L:L) and simulated natural light/dark cycles (L:D), larval release normally occurred in two or more main events at about daily and/or tidal intervals. Since larval release in the crab was expressed with circadian and circatidal periodicity in continuous light and in the absence of tidal cues, it suggests involvement of endogenous timing. Crabs showing daily larval release rhythms released larvae at various times of the day in L:L. In contrast, under simulated L:D cycles, 37 out of 38 crabs released larvae during the dark phase, suggesting nocturnal release of larvae in the crab under natural conditions. Larval release from...
