Long-term Ecosystem Response to Rising Carbon Dioxide and Nitrogen
Rising atmospheric carbon dioxide concentrations and increasing nutrient pollution each generally tend to increase plant growth. What happens to plants when you add both together? What happens to the ecosystem as a whole? We started adding both CO2 and nitrogen to plots in 2006 and found that the whole can be much less than the sum of its parts. We work closely with the Global Change Research Wetland (GCREW) at the Smithsonian Environmental Research Center (drone footage of site) to peer into the future through the eyes of an ecosystem.

Mangrove Migration
Mangroves are moving poleward into marshes all over the world, dramatically changing those ecosystems. We’re looking closely at the causes and evaluating consequences of this dramatic ecosystem change for northeastern Florida.
Plant Influence on Soil Carbon Dynamics
Plants add a great amount of labile carbon to soils but what happens to it after that remains unknown. I am using real-time 13C-CO2 partitioning of respiration to determine the fate of this carbon in soils.
