Flow of Carbon
Join Justine Karst, Restoration Ecologist from the University of Alberta as she discusses her research into the causes and consequences of the flow of carbon from tree roots to soils.
Trees store carbon in roots in response to a variety of events including stress and phenology. The amount of carbon that flows from storage and is released as root exudates affects the activity of root-associated fungi, especially those reliant on living trees for carbon. These fungi play an important role in nutrient and carbon cycling in forests. We tested two predictions: 1) that the more carbon stored, the more carbon ought to be exuded from roots, and 2) that the less carbon stored, the more root-associated fungi will forage for carbon from soils to meet their metabolic needs.
