Alkyl Polyglucoside Compound Influences Freshwater Plankton Community Structure in Floating Mesocosms
… in detergents and cleaners commonly contaminate freshwater systems, therefore developing low-toxicity alternatives derived from natural products such as alkyl polyglucosides (APGs), is important. Although APGs degrade rapidly and reduce chemical exposure time, they can still have toxic effects on …

The distribution, abundance and ecology of mixotrophic algae in marine and freshwater plankton communities
… algae have been found to dominate the nanoplankton assemblage in some aquatic environments, and algal phagotrophy can account for a significant fraction of total bacterivory on occasion. The distribution and abundance of mixotrophic algae have not been widely characterized, however, and the …

Effects of Nutrients and Top Predators on the Structure and Dynamics of a Freshwater Plankton Community: Experimental Studies
… and nutrients in regulating the dynamics of the plankton community. Dynamite Lake contains high levels of bluegill sunfish and low nutrient levels. In both years nutrient and fish levels were manipulated in replicated, factorial-design experiments.

The Influence of Metacommunity Connectivity and Invasive Species on Diversity and Ecosystem Properties: Invasion, Predation by Native Species, and Genetic Diversity of Propagules
… both real and experimental metacommunities using freshwater plankton as a study system. The observational portion of this work (Chapter 2) examined zooplankton and phytoplankton community and ecosystem responses to zebra mussel invasion in 18 reservoirs spanning two natural metacommunities with …
