Interdisciplinary Approaches to Conceptualizing Nonlinear Changes in Permafrost Landscapes II

Session ID#: 34064
Session Description:
Climate change is altering disturbance regimes in permafrost landscapes. Dramatic shifts have been observed or projected in timing and severity of wildfire disturbance, hydrogeology, and permafrost degradation including rapid active-layer deepening and thermokarst development. Because ecosystem responses to these changes depend on feedbacks among physical processes, ecological dynamics, and biogeochemical processes, multiple approaches and disciplines are needed to make meaningful predictions about what permafrost landscapes will look like in 50 or 500 years. Progress is being made toward understanding ecosystem function under historical and current disturbance regimes using remote sensing, pattern and change detection, and chronosequence approaches. These approaches often vary between upland, wetland, and lake systems, limiting our ability to project future states at regional scales. We encourage presentations investigating how ecosystem structure and function respond to changing disturbance regimes in permafrost landscapes and are particularly interested in presentations addressing abrupt or nonlinear landscape change in space and time.
