Dr. Richardson’s research interests in applied ecology center on long-term ecosystem response to large-scale perturbations such as acid rain, toxic materials, flooding, or nutrient additions. He has specific interests in wetland ecosystems, phosphorus nutrient dynamics, and the effects of environmental stress on plant metabolism and growth. Major research focuses on wetlands as nutrient sinks and transformers. His current research activities include: (1) the effects of nutrient additions and hydrology on Everglades phosphorus retention and community changes; (2) heavy metal sorption, storage, and removal from pocosin peatlands; (3) wetland development trends in the southeastern United States; and (4) the effects of highway construction on wetland functions.

My research interests in applied ecology are centered on long-term ecosystem response to large-scale perturbations such as climate change, toxic materials, trace metals, flooding, or nutrient additions. I have specific interests in phosphorus nutrient dynamics in wetlands, and the effects of environmental stress on plant communities and ecosystem functions. Current research efforts have focused on the restoration of wetland and stream functions on the landscape. Newly funded NSF research will focus on the concept of differential nutrient limitation (DNL) as a mechanism to overcome N or P limitations across trophic levels in coastal wetland ecosystems, and the effects of nanomaterials on ecosystem functional responses in wetlands and streams. A new EPA grant will focus on the effects of climate change on invasive species in wetlands.
Current research activities in my lab include: 1) wetland restoration of plant communities and its effects on regional water quality and nutrient biogeochemical cycles, 2) the development of ecosystem metrics as indices of wetland restoration success, 3) the effects of nanomaterials on wetland and stream ecosystem processes, 4) the development of ecological thresholds along environmental gradients, 5) wetland development trends and restoration in coastal southeastern United States, 6) the development of an outdoor wetland research and teaching laboratory on Duke Forest, and 7) differential nutrient limitation (DNL) as a mechanism to overcome N or P limitations across trophic levels in wetland ecosystems.
The objectives of my field research are to test ecological principles and develop new approaches to environmental problem solving. The goal of these studies is to provide predictive models to aid in the management of ecosystems.
