Effect of the Predatory Cladoceran, Cercopagis pengoi, on Lake Ontario’s Lower Food Web

The introduction of invasive species to ecosystems can cause many dramatic changes to the structure and function of that ecosystem. Recently, through ballast water transfers, several Ponto-Caspian species have invaded the Great Lakes including the predacerous zooplankter Cercopagis pengoi. Since the introduction of C. pengoi in Lake Ontario studies have shown the effects of the predator on the zooplankton community present in the lake. The goal of this study is to examine the differences found in three studies of the effect of C. pengoi on Lake Ontario’s lower food web.
