Models were proposed as research tools to test the basic understanding of the structure and function of arctic ecosystems, as a means for providing initial management assessments of potential response to energy-related development, and as a vehicle for extrapolation of research results to other arctic sites and landscapes. This final summary report reviews progress made on models at a variety of scales from nutrient uptake by individual roots to nutrient availability within arctic landscapes, and examines potentials and critical limitations of these models for providing insight on patch and landscape level function in tundra regions.
