Research Interests

My research interests are broad. I identify as an aquatic ecologist with interests in both basic ecological and applied questions.

I graduated from the University of Wisconsin – Madison in 2007 with a B.S. in Biology and German, and a minor in Environmental Studies. While at the University of Wisconsin, I spent many happy days at the Center for Limnology, where I examined why zooplankton body size is often a better predictor of variation around the chlorophyll a/total phosphorus relationship than zooplankton biomass (Kamarainen et al. 2008).

In 2010, I defended my M.S. thesis at Miami University. Under the direction of Drs. Mike Vanni and María González, I studied the effects of light and nutrient variation on food chain efficiency in benthic and pelagic food chains. For this experiment, I manipulated light and nutrients in large (5000 L) mesocosms. I then compared how food quantity and quality predicted top consumer production in simple pelagic (phytoplankton to zooplankton to larval fish) and benthic (periphyton to tadpole) food chains. I used C:nutrient ratios as an indicator of food quality, and also looked at top consumer body nutrients at the end of the experiment (Rowland et al. 2015).

After completing my master’s degree, I spent several years working in local government monitoring lakes, streams and stormwater for the cities of Minneapolis and St. Paul. This work helped give me an appreciation for water resources policy and the enormous impact humans have on the environment. Ultimately, my experiences in local government helped push me to include more applied/conservation aspects in my ecological research.

In my current work, I use a combination of field studies, mesocosms, and quantitative tools to understand some basic questions about pond food webs and ecosystem functioning. These questions include examining the relative strength of top-down vs. bottom-up dynamics in ponds, manipulating cross-ecosystem subsidies of leaf litter, and examining green vs. brown energy pathways in ponds. I am especially interested in the role of pond-breeding amphibians in shaping pond processes (for example nutrient cycling and primary production), and how basal resources of a pond influence the success of larval amphibians.
