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 The database provides a listing of fire research publications relevant to Alaska and a venue for sharing unpublished agency reports and works in progress that are not normally found in the published literature.

We are at an exciting juncture in ecological research due to the simultaneous emergence of several new technologies. High-powered microcomputer and workstation capabilities are now available at modest cost for image processing, new mathematical and statistical techniques for…

Finally, ecologists should consider becoming more involved in the scientific and political debates that set the priorities for Mission to Planet Earth. I wonder if the recent controversies of the United States Global Change Research Program would have been so focused on…

Finally, it may be that ecologists only recently have become interested in processes and patterns occurring at scales amenable to remote sensing. There is a growing need to understand ecological relationships in the context of a changing world (Lubchenco et al. 1991); we hope…

Fire as an ecological factor is of major importance in the distribution, species composition, and productivity of the sand pine scrub community, both in its own right and as it interacts with other factors such as animal influences, trophic factors, soil particle movement, and…

Wildfire is a major disturbance factor in boreal forests where it is important in rejuvenating soil properties and encouraging tree regeneration and growth. However, the mechanisms behind these effects are poorly understood and little is known as to the ecological effects of…

Changes in foliar chemistry resulting from changes in forest-floor and mineral-soil moisture availability, forest-floor microbial energy supply, and nitrogen availability were investigated across the successional sequences in both upland and floodplain landscape positions. Three…

Deteriorating forest health is causing unprecedented damage to the boreal forests of Alaska. Forest health is a complex issue that must be adressed within the context of ecosystem management and the goal of managing ecosystems for long-term productivity and maintaining…

State factor controls of soil and forest development were examined in floodplain primary and upland secondary successional ecosystems along the Tanana River in interior Alaska. Topography is the principal difference in state factor control of structure and function of these…

An experimental approach is essential to understanding the controls on ecosystem function. An explicit focus on state factors provides a framework that logically leads to formulation and experimental testing of hypotheses. In this article, we present an evaluation of controls on…

Data were collected during June-July 1988 on the regeneration of black spruce (Picea mariana) and jack pine (Pinus banksiana) after an intense fire in June 1983. The main factors analysed were (i) effects of organic matter thickness on growth of the regeneration, (ii) spatial…

The paper describes attributes of space, time, and process in terms of their relations to wildland fire. It then presents a generic framework, based on eight interrelated scale classes for space, time, and process. The effects of changing scales are discussed in a wildland fire…

Predation, especially wolf (Canis lupus) predation, limits many North America caribou (Rangifer tarandus) populations below the density that food resources could sustain. The impact of predation depends on the parameters for the functional and numerical response of the wolves,…

We compared characteristics of 2 black bear (Ursus americanus) populations living in middle-aged (1947 burn area) and recent (1969 burn area) burned forest stands on the Kenai Peninsula, Alaska, during 1982-87. Densities of bears on the 1947 (205 bears/1,000km2) and 1969 (265…

The effects of fire on the Aikens Lake population of woodland caribou (Rangifer tarandus caribou) were studied over a 2-year period. Quantity, quality, and accessibility of forages were determined in recently- burned (5-yr-old) habitats and compared to those in intermediate (37…

Random environmental influences, such as snow cover, are widely regarded as an integral feature of caribou population dynamics. We conducted computer simulations to explore the ramifications of such stochastic variability for caribou demography. We devised 4 models with…

One of the greatest challenges in global-change research is to predict the future distribution of vegetation. Most models of vegetation change predict either the response of a patch of present vegetation to climatic change or the future equilibrium distribution of vegetation…

Stand data from Lutz and Sitka spruce forest types occurring on the Kenai Peninsula were analyzed by tree-based classification and abductive inference to develop decision models for classifying spruce beetle hazard. Model development and validation data sets contained 286 and 88…

Forest community type was the most important variable determining risk of a spruce beetle (Dendroctonus rufipennis Kby) outbreak. Black spruce (Picea mariana B.S.P.) communities exhibited low to moderate risk overall, but stands in these communities with deep accumulations of…

Fire blight was for the first time observed in a pear orchard in southern Sweden in 1986. Since 1989 the disease has spread along the south and west coast with the most frequent number of new outbreaks in 1990. Besides pear, hawthorn, apple, Sorbus aria and Cotoneaster…

During 1991-94 we tested whether martens (Martens americana) selectively used postfire seres in the Alaskan taiga and whether selection could be explained by differences in marten hunting behavior, habitat, prey abundance, or demography. Forest seral stages included early-…

The coupling of synoptic scale weather conditions with local scale weather and fuel conditions was examined for 2551 fires and 1,537,624 lightning strikes for the May-August fire seasons in 1988, 1989, 1992, and 1993 in Alberta and Saskatchewan. The probability of lightning fire…

Hot-spotting containment rates were determined for 18 fires of various intensities in two common boreal forest cover types: 8 in jack pine (Pinus banksiana Lamb.) and 10 in black spruce (Picea mariana (Mill.) B.S.P.). Hot-spotting containment rates did not differ significantly…
