Benthic Macroinvertebrate communities of Southwestern Lake Ontario Following Invasion of Dreissens
Haynes, James M.; Stewart, Timothy W.
Changes in benthic macroinvertebrate communities inhabiting natural cobble and artificial reef substrates in southwestern Lake Ontario were quantified before and after the invasion of dreissenid mussels in the late 1980s. Dreissenids comprised 79% and 93% of the cobble and reef communities in 1991-1992 (post-invasion) and replaced the amphipod, Gammarus fasciatus, which was the most abundant species at both habitats in 1983 (pre-invasion). Total abundance of non-Dreissena species was significantly greater in 1991-1992 than in 1983. Comparisons of macroinvertebrate community similarity in 1983 and 1991-1992 indicated that previously established taxa did not change substantially between sampling periods, but their proportions in the community did. Although many factors may have contributed to the changes we observed, our results support theories that Dreissena is facilitating energy transfer to the benthos by pseudofecal/ fecal deposition and that mussel colonies are providing additional habitat for other invertebrate taxa.

Benthic macroinvertebrate communities were quantified at natural cobble and artificial reef sites in Lake Ontario in 1983 (7 y pre-Dreissena invasion) and in 1991-1992 and 1999-2000 (1-2 and 9-10 y post-Dreissena invasion, respectively). Overall, the natural cobble community had higher species diversity and community abundance than the artificial reef community. While taxonomic composition of both communities remained consistent during the study period, organism abundance (excluding Dreissena) increased sharply from 1983 to 1991-1992, and that all taxa declined to 1983 levels by 1999-2000. From 1991-1992 to 1999-2000, Dreissena bugensis, which mostly replaced D. polymorpha, and Echinogammarus ischnus (all invasive species) appeared in the studied community. We conclude that the transition from D. polymorpha to D. bugensis and processes associated with the ongoing oligotrophication of Lake Ontario are responsible for the reduced density of large-bodied Dreissena in the nearshore region of the lake, and that changes in the Dreissena population are largely responsible for changes in the non-Dreissena benthic macroinvertebrate community.

We determined how much suitable habitat for Pirate Perch remains in Buttonwood Creek, sampled those habitats to determine where the species still exists in the creek, and predicted the likely impact of a bridge replacement and associated channel alterations on the Pirate Perch population
