【摘要】 从2000年3月到2002年10月对中国沿海海产腹足类性畸变的大范围调查过程中 ,在广东省汕头港、湛江港和厦门港分别采集到西格织纹螺 (Nassariussiquijorensis)、胆形织纹螺(Nassariusthersites)和节织纹螺 (Nassariushepaticus)等3个种 ,解剖观察发现3种织纹螺的雌性个体都发生了性畸变现象。根据织纹螺性畸变的发展过程 ,对目前的性畸变发展划分体系作了新的修改和补充。通过对比性畸变个体与正常雄性个体的特征 ,探讨了雄性个体结构特征在性畸变过程中的效应更多还原

【Abstract】 From March 2000 to October 2002, a large scale investigation was conducted in the coastal waters of China for imposex in gastropod. Nassarius siquijorensis, N. thersites and N. hepaticus were collected from Shantou Harbor, Zhanjiang Harbor and Xiamen Harbor, respectively. All these three N. spp. were found to be affected by imposex. According to the imposex development of N. spp, the present imposex classification system was updated. The structural effect in males was also discussed by comparing the morphological characteristics of normal males with the imposex specimens.更多还原
