摘要
一般动物(含人类)的生理活动和行为都有不同程度的周期性(periodicity)或节奏性(rhythemicity),而这些现象的表现并不一致:有的较明显,很易发觉(如昼夜垂直移动、体色变化等),而有的较隐蔽,不易发现(如视网膜色素移动等)。生物钟(biological clock)是受时间机制(timing mechanism)调节或控制的一种节奏性或周期性的生理活动(较为隐蔽)
The biological clock in marine invertebrates,with special reference to Crustacea, is accounted in two aspects: namely, rhythm and mechanism. The former sonsists of three topics, i.e., tidal thythm, lunar rhythm and diurnal rhythm, and the latter deals mainly with metabolism and hormone, taking chromatophorotropic hormone secreted by Sinus and X glands inside the eye-stalk of schrimps and crabs as an example, which is responsible for the diurnal color change in Crustacea. It is considered that in future research , more attentions should be paid to the important role of hormones in timing mechanism and in the control and regulation of physiological rhythms of biological clock.
