The Boreal System illustration depicts some of the landscape characteristics, changes and drivers of change in the boreal ecosystem prevalent throughout Alaska and Northwest Canada. This illustration was developed as part of the Integrated Ecosystem Model project supported by the AK CASC.

The vector illustration can be used as a PDF or opened and edited using Adobe Illustrator.

The Icefield to Ocean illustration depicts the important linkages between glaciers, glacier change, and the ocean. This illustration is the product of collaborations formed in research projects and through a March 2013 workshop supported by the AK CASC. The figure is published in this publication.

Funded Title: 
Differential Effects of Climate-Mediated Forest Change on the Habitats of Two Ungulates Important to Subsistence and Sport Hunting Economies
Location: 
Alaska and Northwest Canada
Duration: 
April 1, 2015 to April 1, 2016

Climate change is a complex process that may affect the food resources of different species of wildlife in contrasting ways. Moose and caribou are important to both subsistence and sport hunting economies throughout Alaska, but their winter diets are quite different; caribou focus on snow covered ground hugging lichens while moose focus on the twigs of erect deciduous shrubs that protrude above the snow.

This report describes the progress of the IEM project from January 1, 2013 through August 31, 2014, and specifically reports on new data products developed during this time period. Categories of data products include climate, land cover, soil properties (including permafrost), fire disturbance, treeline and vegetation dynamics, plant productivity, and carbon storage.

In this project we are developing, testing, and applying the Integrated Ecosystem Model (IEM) for Alaska and Northwest Canada to forecast how landscape structure and function might change in response to how climate change influences interactions among disturbance regimes, permafrost integrity, hydrology, vegetation succession, and vegetation migration.

"CO2 and CH4 Fluxes and Net C Storage Following Permafrost Thaw in Interior Alaska" was a poster presented at the American Geophysical Union Fall 2012 Meeting in San Francisco, California.

"The tool of microbial genomics for interpreting the lability of permafrost carbon and potential greenhouse gas feedbacks from ecosystem change" is a presentation by M.P. Waldrop, K.P. Wickland, R. Machelprang, and J. Hultman. The invitd talk was presented at the American Geophysical Union Fall 2012 Meeting in San Francisco, California.

"Dynamic Model Coupling" is a poster presented at the American Geophysical Union Fall 2012 Meeting in San Francisco, California.

"The Alaska Integrated Ecosystem Model: An Interdisciplinary Tool to Assess the Responses of Natural Resources in Alaska to Climate Change" was a poster presented at the American Geophysical Union Fall 2012 Meeting in San Francisco, California.

"Assessing the Impacts of Glacier Change in the Coastal Temperate Rainforest" was a presentation created after the Juneau Glacier Workshop for a public audience in Juneau, Alaska. It gives a borad overview of the various ways that glaciers interact with other parts of the coastal temperate rainforest.
