Dr. Carey's research integrates population, community, and ecosystem ecology to examine how natural and anthropogenic perturbations affect freshwater systems. A current research focus is on understanding how feedbacks between microbial and plankton taxa, food webs, and nutrient cycling can mediate ecosystem resilience to eutrophication and climate change. We work across lakes, reservoirs, and streams, and use models, field experiments, and long-term data analysis to determine how stressors affect both biological communities and ecosystem services.
