Plants convert sunlight into energy and initiate symbiotic partnerships with fungi through their roots. In these symbioses, plant-derived carbon (C) is traded with fungi for water and nutrients. I plan to investigate exactly how C flows through belowground fungal networks in a grassland prairie plot. Determining the fate of C is important in understanding plant-fungal trade systems, but perhaps more so in specifying the relationship between soil fungal C and climate change mitigation.
