Landscape Heterogeneity

How does landscape organization control permafrost evolution and associated C and nutrient fluxes in a changing environment?

Landscape heterogeneity considers how vegetation, biogeochemistry, and hydrology are influenced by regional landforms such as ridges, valleys, and drainage basins. Variation in landscape form and function are simplified for input into models while still retaining fine-scale features with the strongest influence on climate feedbacks.
