The Alaska Reference Database originated as the standalone Alaska Fire Effects Reference Database, a ProCite reference database maintained by former BLM-Alaska Fire Service Fire Ecologist Randi Jandt. It was expanded under a Joint Fire Science Program grant for the FIREHouse project (The Northwest and Alaska Fire Research Clearinghouse). It is now maintained by the Alaska Fire Science Consortium and FRAMES, and is hosted through the FRAMES Resource Catalog. The database provides a listing of fire research publications relevant to Alaska and a venue for sharing unpublished agency reports and works in progress that are not normally found in the published literature.

The caribou (Rangifer tarandus) of Arctic Alaska are gregarious, frequently mobile and occupy environment too harsh to support more than a limited spectrum of specialized animals. Although most previous work on caribou has been conducted during the short summer phase of their…

During the summer of 1987, 500-1000 caribou became stranded on Rideout Island in Bathurst Inlet, Northwest Territories. The 40 km2 island did not have sufficient forage to support the animals until freeze-up, and the caribou eventually died from malnutrition after severely…

Heart rot fungi cause substantial economic loss in many forests, but their ecological roles in altering the speed or direction of succession are frequently overlooked. As heart rot induces trees to die standing or, more commonly, by bole breakage, the fungi that cause heart rot…

Yellow cedar (Chamaecyparis nootkatensis) is a valuable tree species that is experiencing an extensive forest decline on over 200,000 ha of unmanaged forest in southeast Alaska. Biotic factors appear secondary and some abiotic factor is probably the primary cause of this…

Alaska yellow-cedar (Chamaecyparis nootkatensis (D. Don) Spach) has been declining and dying for a long, but undetermined, span of time in remote and undisturbed forests of southeast Alaska. Aerial photographs indicate mortality was widespread by 1927. The dates of death for…

Alaska-cedar, Chamaecyparis nootkatensis (D. Don) Spach, has been dying in undisturbed forests throughout southeast Alaska for the last 100 years. To determine if decline spreads, boundaries of mortality at seven sites with decline were mapped using aerial photographs taken in…

Concentrations of P, K, Ca, Mg, Mn and Zn in black spruce foliage were examined in relation to forest succession on north slopes in interior Alaska. Decline in levels of P and K in the foliage corresponds with rapid decline in forest productivity. Levels of P and, to a lesser…

Forest succession on north slopes in interior Alaska results in the development of sphagnum bogs on sites formerly occupied by productive forest. This process is one of gradual deterioration of site associated with the accumulation of moss layers on the forest floor. Advancing…

The data base of the Planning and Inventory Branch, B.C. Ministry of Forests, consists of approximately 7000 forest cover maps, descriptive statistics, growth information and depletion data. This data base must be current and hence, needs to be updated annually. Maintaining an…

The effects of forest fire smoke on sky polarization and animal orientation are practically unknown. Using full-sky imaging polarimetry, we therefore measured the celestial polarization pattern under a smoky sky in Fairbanks, Alaska, during the forest fire season in August 2005…

Black bears in the interior of Alaska emerging from winter dens in early May spend much of the first three months of their annual active season in riverbottom and other lowland situations where the shoots and new leaves of green vegetation, especially Equisetum spp. Compose the…

Black spruce (Picea mariana (Mill.) BSP) is a common treeline species in eastern Canada but rare at treeline in Alaska. We investigated fire and substrate effects on black spruce populations at six sites along a 74 km transect in the Brooks Range, Alaska. Our southern sites, on…

Black spruce (Picea mariana (Mill.) BSP) is the dominant species in interior Alaska but it is largely absent from the arctic tree line. To evaluate the importance of climate and fire as controls over the species distribution, we reconstructed stand history at three sites near…

Boreal tree species are expected to invade tundra ecosystems as climate warms. Because forested ecosystems differ from tundra ecosystems in a number of climatically relevant characteristics, this advance of the altitudinal and latitudinal tree limit may ultimately feedback on…

We examined the ways grizzly bears (Ursus arctos), wolves (Canis lupus), and black bears (Ursus americanus), and humans affected moose (Alces alces) numbers in a 6,310-km2 area in the southwest Yukon during 1983/85. We documented pregnancy rates, birth rates, and causes and…

Tundra rangelands of Alaska and northern Canada occupy about 200,000 and 900,000 square miles respectively. The tundra supports far lower numbers of large grazers than other natural areas, averaging less than 100 lb per square mile. Forage quality of tundra plants is high…

Reindeer (Rangifer tarandus), introduced to St. Matthews Island in 1944, increased from 29 animals at that time to 6,000 in the summer of 1963, and underwent a crash die-off the following winter to less than 50 animals. In 1957, the body weight of the reindeer was found to…
