Biomass of Freshwater Crustacean Zooplankton from Length–Weight Regressions
We present equations for calculating dry weight from body length for 14 common and widely distributed taxa of crustacean zooplankters; these were generated by regression from weights of individuals...

Isolation and Characterization of Microcystins, Cyclic Heptapeptide Hepatotoxins from a Lake Erie Strain of Microcystis aeruginosa
Cyanobacteria (blue-green algae) dominated by Microcystis aeruginosa were detected in phytoplankton samples collected from several sites in the western basin of Lake Erie during the summer of 1996Expand

Temporal Trends in Lake Erie Plankton Biomass: Roles of External Phosphorus Loading and Dreissenid Mussels
Abstract We compare the results of lakewide plankton studies conducted during 1996–2002 with data reported in the literature from previous years to evaluate the effectiveness of continued nutrientExpand

Re-eutrophication of Lake Erie: Correlations between tributary nutrient loads and phytoplankton biomass
Abstract Both abiotic and biotic explanations have been proposed to explain recent recurrent nuisance/harmful algal blooms in the western basin and central basin of Lake Erie. We used two long-termExpand

Soluble nitrogen and phosphorus excretion of exotic freshwater mussels (Dreissena spp.): potential impacts for nutrient remineralisation in western Lake Erie
SUMMARY 1. Recent increases in phytoplankton biomass and the recurrence of cyanobacterial blooms in western Lake Erie, concomitant with a shift from a community dominated by zebra mussels (DreissenaExpand

Vertical mixing and weak stratification over zebra mussel colonies in western Lake Erie
Zebra mussels (Dreissena polymorpha) are an invasive species that have been implicated in the reduction of algae stocks in the near-shore environment of western Lake Erie. To determine theirExpand

Estimating the effective clearance rate and refiltration by zebra mussels, Dreissena polymorpha, in a stratified reservoir
Summary 1. The grazing impact of zebra mussels, Dreissena polymorpha Pallas, is often evaluated by applying the individual filtration rate measured in the laboratory to the field abundance andExpand

Effects of recent ecosystem changes on the recruitment of young-of-the-year fish in western Lake Erie
We compared the variability in forage fish recruitment over the last 27 years against major ecological changes that occurred in Lake Erie over the same time period. During a period of high adultExpand

Spatial-Dynamic Modeling of Algal Biomass in Lake Erie: Relative Impacts of Dreissenid Mussels and Nutrient Loads
Over the past several decades, reductions in phytoplankton stocks and increased water clarity in Lake Erie have resulted from phosphorus load abatement and the introduction of zebra DreissenaExpand

Ontogenetic Diet Shift in Lake Erie Age-0 Yellow Perch (Perca flavescens): A Size-Related Response to Zooplankton Density
Through field studies, we demonstrated that age-0 yellow perch (Perca flavescens) in western Lake Erie underwent an ontogenetic diet shift from exclusively zooplankton to mainly benthic prey duringExpand
