Management Notes for this Location:
Modification of natural benthic communities: The establishment of Dreissena polymorpha and D. bugensis coincided with a drastic decline of native amphipod Diporeia spp. (Owens & Dittman, 2003).
Reduction in native biodiversity: 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).
