Fine-root dynamics and aboveground-belowground linkages in forest ecosystems

Phenology, lifespan, and decomposition of fine roots control ecosystem processes.

Description/abstract

The phenology, lifespan, and decomposition of fine roots mediate fluxes of carbon and nutrients within plants and across terrestrial ecosystems. Leveraging institutional support from the Morton Arboretum and an NSF grant focused on root decomposition, this umbrella project unites over a decade of research with collaborators in China, the University of Minnesota and elsewhere in the United States and pushes forward with new installations to understand how different tree species allocate resources to build and maintain roots and how these “choices” then manifest diverse strategies for soil resource acquisition across seasons and years.
