| Impact Description | Increasing amounts of pseudofeces and biodeposits could also have an impact on multiple trophic levels via changes to the physical environment. A current study in Brocton Shoal, Lake Erie, suggests that colonization of lakebed areas by dreissenid mussels (Dreissena bugensis) and the consequent filling of remaining interstitial spaces with pseudofeces and fine-grained sediments may significantly eliminate valuable habitat native habitat . Brocton Shoal, once thought to be an important area for lake trout spawning, has diminished suitability as a spawning ground. |
