Abstract Details

2010, Doctor of Philosophy, Ohio State University, Environmental Science.
This dissertation details a comprehensive study of the ecology and development of the soil and carbon, nitrogen and phosphorus cycles in freshwater marshes. Beyond broadening our understanding of wetland development and ecology, this work intents to enlighten evaluation of wetland mitigation policy, as well as facilitate the success of wetland creation projects. Ten created and five natural freshwater marshes of central Ohio are the focus throughout the study. One of the central chapters (Ch. 3) compares structure and function between created and natural wetlands. The most important finding is that there are significant differences between created and natural wetland soils; this leads to smaller nutrient stocks and slower nutrient cycles in the created wetlands. Time-to-equilibrium estimates for the development of soil and nutrient-related functions are explored in Ch. 4. It is determined that overcoming these differences will require more time than is acceptable for most mitigation policies. The final two chapters explore the habit and ecology of arbuscular mycorrhizae (AM) in created and natural marshes. The presence of AM was high in both created and natural wetlands and across created wetland age. Given their prevalence and known role in other ecosystems, including AM in wetland creation and restoration projects deserves more focus.
