Changes in the Source/Sink Relationships of the Alaskan Boreal Forest as a Result of Climatic Warming
A modified version of the LINKAGES ecosystem simulation model is used to access the changes in the role of forests in the interior of Alaska to act as a source or sink of carbon over a fifty-year period. The study area is the Tanana Valley State Forest (TVSF). The TVSF occupies an area of 5523 hecta...
