福建崇武潮间带滨螺科的生态研究

Study on the Family Littorinidae on the Rocky Intertidal Zone of Chongwu,Huian,Fujian

研究福建崇武岩相潮间带三种滨螺的生态 :粒结节滨螺 (Nodilittorinaexigua)、塔结节滨螺 (N.pyramidalis)、粗糙滨螺 (Littorina scabra) .粒结节滨螺为优势种 ,三种滨螺的分布均达于中潮区的下限 ,具有明显的垂直分布 .随季节变化 。

Three species of the family Littorinidae, Nodilittorina exigua,N.pyramidalis,Lirror inascabra ,on the rocky intertidal zone of Chongwu,Huian,Fujian have been studied.The result shows that N.exigua is the dominant species and the distribution of all the three species reaches the bottom limitation of the middle intertidal zone,exhibiting obviously vertical distribution.The habitat density varies with the seasonal changing.
