Factors that regulate the zooplankton community structure of a turbid, hypereutrophic Great Lakes wetland

We sampled zooplankton from mid-May to early September over 2 years to study the spatial and seasonal distribution of animals in a large urban wetland of Lake Ontario. Samples were from several habitat types including open water, vegetated areas, fast-flow areas, and a sewage lagoon. Mean seasonal densities ranged from 17 individuals/L (5 µg/L) in fast-flow areas to 1800 individuals/L (1100 µg/L) in low-flow, highly vegetated areas. All of our …
