Freshwater science to inform policy

We study aquatic ecosystems--almost exclusively inland freshwaters. We are particularly interested in the availability of three essential building blocks of life: phosphorus, nitrogen, and carbon. We design field studies and perform experiments to help understand how altering levels of these elements in isolation and coupled with potential contaminants may cause detrimental and even irreversible damage to ecosystems in which we rely on for water, food, and recreation. Along the way, we make discoveries that contribute to our "textbook" understanding of our planet. In academic terms, we span the boundary of basic and applied science.


Moncie Wright successfully defended her dissertation "Interactions Between Titanium Dioxide Nanoparticle Exposure and Grazing Organisms on Periphyton Biomass and Community Composition" and graduated with the Doctor of Philosophy degree in Biology from Baylor University on Saturday, December 15, 2018, in the Ferrell Center, Waco, Texas.
Caleb Robbins successfully defended his dissertation, "From Landscapes to Streams: The Pattern and Function of Labile Dissolved Organic Carbon" in July 2018. Caleb graduated with the Doctor of Philosophy degree in Biology from Baylor University on August 11, 2018, in the Ferrell Center, Waco, Texas.
Brittany Perrotta coauthored two high-impact papers in 2018: "Engineered nanoparticles interact with nutrients to intensify eutrophication in a wetland ecosystem experiment", published in Ecological Applications and "Size-Based Differential Transport, Uptake, and Mass Distribution of CeO2 Nanoparticles in Wetland Mesocosms", published in Environmental Science & Technology. Way to go, Brittany!
Dan Hiatt published his 2nd dissertation chapter entitled "Effects of stream velocity and phosphorus concentrations on alkaline phosphatase activity and carbon:phosphorus ratios in periphyton" in the journal Hydrobiologia. Dan is in the home stretch, just wrapping up that last chapter. Go Dan, go!
Stephen Cook, a Ph.D. student in the Aquatic Ecology Lab, received news that his first paper, "Freshwater eutrophication sharply reduces temporal beta diversity," will be published in Ecology, the flagship journal of the Ecological Society of America. Congratulations, Stephen!
Research Spotlight

We were selected by a joint committee from Oklahoma and Arkansas to conduct a multi-year study to determine a threshold level of phosphorus for the Designated Scenic Rivers of Oklahoma. The $600,000 study just wrapped up. Download the final report and view photo gallery and video clips from the study
