Global Change in Arctic and Boreal Ecosystems

Arctic and boreal ecosystems are rapidly changing. An important research challenge is to develop a predictive understanding of how disturbance regimes, vegetation dynamics, and permafrost melt will influence ecosystem services, atmospheric composition, and the climate system.
