摘要
本文在室内无潮汐因子作用条件下对采集于青岛太平湾基岩海岸潮间带的短滨螺进行观察,发现其具有和潮汐同步的排卵和运动节律性。30d后,仍能观察到排卵的潮汐节律性。1a后,短滨螺不呈现排卵的潮汐节律性。
Littorina brevicula, co.llected fr,om the rocky intertidal zone of Taipingjiao at Qingdao, P. R. China, presents tidal rhythms of egg-releasing and activity under the constant condition in laboratory. The number of eggs released by L. brevicula and its activity increases during the flood of tide and decreases during the ebb tide. L. brevicula loses its activity tidal rhythm in the constant laboratory condition after one month, but loses its egg-releasing tidal rhythm after one year. The tidal rhythms off egg-release and activity of L. brevicula are controlled by both the endogenous biological clock and exogenous periodical tidal factor.
