Population Dynamics and Production of Limnetic Crustacean Zooplankton in Five Southeastern Nebraska Flood Control Reservoirs

GLEN ROY HELZER, University of Nebraska - Lincoln

Abstract

Many hundreds of articles in limnological literature contain information about limnetic zooplankton communities. This information has come from studies conducted either in controlled laboratory conditions or in nature where no controls are imposed. The laboratory studies yield valuable data but environmental conditions are seldom the same as those of the natural habitat. The field approach was used in this study, supplemented by rate function information obtained from the laboratory.Aquatic crustaceans (Cladocera and Copepoda) were chosen for study because of their importance in the limnetic food chain and because the highly visible eggs are carried by the females making them well suited for studies of population dynamics and production (Edmondson, 1960; Hall, 1964; Wright, 1965). Unfortunately, no techniques have been developed for studying production of entire assemblages of zooplankton populations (Edmondson and Winberg, 1971) as has been done for the study of primary production (Vollenweider, 1969).
