降水对日本菊花螺胚胎发育和幼体孵化的影响
The effects of rainfall on the embryonic development and larval hatching of Siphonaria japonica (Donovan, 1824)
摘要
Abstract
As a common intertidal Pulmonata species,Siphonaria japonica(Donovan,1824)lays its egg ribbons on the intertidal rocky shores. Therefore, rainfall has potential effects on the embryonic development and larval hatch-ing of S. japonica. To investigate the effects of rainfall on the embryonic development and larval hatching of S.japonica,we examined the effects of simulated rainfall on the embryonic development,the cumulative number of larval hatching, and the value and occurrence time of hatching peak in the egg ribbons. We also analyzed the effects of natural rainfall on the cumulative number of larval hatching, the value and occurrence time of hatching peak in different stages of egg ribbons. These results indicated that simulated rainfall had pronounced impacts on the em-bryonic development and larval hatching of egg ribbons (P < 0.05). However, natural rainfall did not affect the cu-mulative number of larval hatching (P > 0.05), but dramatically accelerated the rate of larval emergence (P < 0.05). These results will provide the basic data for understanding the impacts of rainfall on the reproduction and popula-tion dynamics of intertidal gastropods.关键词
