Modeling Interactions Between Environmental Management and Ecosystem Services in a Dynamic Freshwater Ecosystem

Roy, Eric Daniel

Abstract Details

2008, Master of Science, Ohio State University, Food Agricultural and Biological Engineering.
I developed an ecological-economic model representing the Sandusky region of Lake Erie to explore the relationship between internal ecosystem change and management of external phosphorus loading. The model was comprised of two sub-models: an ecological unit model and a phosphorus management model reflecting the societal benefits and costs of phosphorus regulation. These two sub-models formed a dynamic feedback loop including freshwater ecology, ecosystem services, and phosphorus management. Climatic fluctuations in phosphorus loading caused significant variations in the quality of ecosystem services between years. Decreases in ecosystem resistance to eutrophication caused by dreissenid mussels created multiple stable states of management compromise. Adaptive management benefited ecosystem services during mussel invasion scenarios, while unresponsive management was biased towards groups discharging phosphorus. Large-scale wetland restoration shifted management compromise to states characterized by less on-site management and higher environmental quality. The perturbation-based approach taken here illustrates that equilibrium in ecological-economic systems over time is unlikely.
