RESEARCH STATEMENT
Ecological interactions between freshwater consumer and prey species are the primary foci of my lab group, the Plankton Ecology and Limnology Laboratory (PEL Lab). Our studies have covered a broad range of aquatic organisms, from bacteria to fish, with emphases on lake and reservoir ecosystems. We are particularly interested in understanding how consumers affect community and ecosystem level dynamics through direct and indirect effects on planktonic microbial assemblages via mechanisms such as selective consumption, alteration of competitive forces, and changes in nutrient cycling dynamics. Laboratory and field experimentation play key roles in PEL Lab research, and we typically employ multiple but separate approaches to both basic and applied questions. Graduate and undergraduate students working in the PEL lab are free to explore any topic in aquatic ecology and evolutionary biology. Current student research includes the investigation of factors that affect distributional patterns of the harmful algal bloom (HAB) species Prymnesium parvum across the regional landscape using qPCR and biogeochemical surveys; experimental analyses of acute and chronic impacts of HAB toxins on fish and zooplankton; analytical and toxicological characterization of HAB toxins; analysis of the effects of environmental variation, including HABs, on population dynamics, abundances, and reproductive strategies of monogonont rotifers; the study and metagenomic documentation of microbial diversity across environmental gradients; study of the ecology of invasive Zebra mussels and potential their interactions with the invasive Harris mud crab in Lake Texoma; genomic sequencing and gene expression studies in Prymnesium; and the use of remote sensing technologies for quantification of water quality in regional lakes.
