狀態: 外來 入侵: 出現紀錄: ????? 來源: Owens & Dittman, 2003 影響: 改變自然底棲生物群落: The establishment of Dreissena polymorpha and D. bugensis coincided with a drastic decline of native amphipod Diporeia spp. (Owens & Dittman, 2003). 降低本地生物多樣性: In response to the disappearance of Diporeia spp., believed to have resulted from the introduction of Dreissena polymorpha and D. bugensis, populations of two native benthivores, slimy sculpin and lake whitefish, collapsed in eastern Lake Ontario, perhaps due in part to starvation, because Diporeia was their principal prey (Owens & Dittman, 2003). 最後修改 : 10/12/2009 4:19:12 p.m.
