摘要
牛蛙是ISSG/SSC公布的 10 0种最危险的入侵种之一 ,也是进入我国最早、分布最广和危害最大的外来两栖动物 .1980年以后 ,由于野外放养和人工驯养地区的迅速扩大 ,野化种群的数量增加很快 ,对土著蛙类和农田生态系统的稳定形成了严重威胁 .本文依据近年来发现的 3个新案例 ,初步分析了牛蛙在我国的分布状况和牛蛙成功入侵我国的主要原因 ,以及牛蛙在生物链中的位置和危害 ,并提出了 3条相应的管理对策 .图 1表 2参
Bullfrog (Rana catesbeiana Show) is one of the 100 worst invasive species in the world listed by ISSG/SSC. Among seven alien species of amphibians found in China, the bullfrog is the earliest invader with the widest distributions, and its native successful breeding and reproduction have been conformed recently in the wild. The bullfrog has gradually become a major threat to native frogs on their habitats and agricultural ecosystem. So, it is very urgent and necessary to find out effective management strategies to control its further pervasion. Based on the analysis of three new successfully invasive cases of bullfrogs in southwest China, three management strategies are presented. Fig 1, Tab 2, Ref 18
