Ongoing climate change may affect ecosystems and the services they provide to Alaska and the nation. The physical and biological components that characterize arctic and boreal ecosystems are tightly linked and sensitive to climate change. Understanding the effects of climate change on ecosystem services is challenging due to the lack of available tools to forecast the rate and ways that landscape structure and function may respond to change. The Alaska Integrated Ecosystem Modeling (IEM) Project is a collaborative project that takes a multi- disciplinary approach to understanding ecosystem change. This presentation will describe the development of a dynamically linked model framework for Alaska's terrestrial ecosystems that incorporates climate-driven changes to vegetation, disturbance, hydrology, and permafrost, and their interactions and feedbacks.
