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 The database provides a listing of fire research publications relevant to Alaska and a venue for sharing unpublished agency reports and works in progress that are not normally found in the published literature.

From 1980- 1989, fires burned 32 440 km² of boreal forest, 200 km south of the forest-tundra border in northern Quebec, Canada. An assessment of the impact of fire on tree population densities was carried out by comparing the number of Pinus banksiana and Picea mariana in 83…

We present a simple empirical model that allows an estimation of mortality due to spruce budworm (Choristoneura fumiferana) outbreak in relation to fire frequency and site characteristics. The occurrence of a recent spruce budworm outbreak around Lake Duparquet (48º 30' N, 79º…

In this study, we measured rough harvester ant, Pogonomyrmex rugosus Emery, foraging activity, numbers and types of food items collected by foragers, ant foraging efficiency, and maximum foraging distances in a desert grassland site in central New Mexico before and after an…

We review and compare well-studied examples of five large, infrequent disturbances (LIDs)--fire, hurricanes, tornadoes, volcanic eruptions, and floods--in terms of the physical processes involved, the damage patterns they create in forested landscapes, and the potential impacts…

In this article, we develop a heuristic model of ecosystem-disturbance dynamics that illustrates a range of responses of disturbance impact to gradients of increasing disturbance extent, intensity, or duration. Three general kinds of response are identified and illustrated: (a)…

All species have evolved in the presence of disturbance, and thus are in a sense matched to the recurrence pattern of the perturbations. Consequently, disturbances within the typical range, even at the extreme of that range as defined by large, infrequent disturbances (LIDs),…

Because some consequences of fire resemble the effects of industrial forest harvesting, forest management is often considered as a disturbance having effects similar to those of natural disturbances. Although the analogy between forest management and fire disturbance in boreal…

Introduction...'Fire and climate are closely linked (Swetnam 1993). According to simulations of various general circulation models (GCMs), the earth's climate will be 1-3.5º C warmer by the end of the next century due to increasing atmospheric concentrations of radiatively…

Mimicking of natural disturbance for ecosystem management requires an understanding of the disturbance processes and the resulting landscape patterns. Since fire is the major disturbance in the boreal forest, three widely held beliefs about fire behavior and resulting landscape…

Forest Service expenditures for fire presuppression and suppression activities increased from $61 million in FY 1970 to $951 million in FY 1994. Yet, real (net of inflation) expenditures have not increased significantly since FY 1970, if FY 1994 expenditures are excluded. During…

The allocation of resources to dispersal and reproduction in relation to habitat persistence was investigated in three closely related buprestid beetles Melanophila acuminata, Phaneops cyanea and P. formaneki. Their respective breeding habitats are recently burned forest, forest…

The adult phenology of the fire-adapted Melanophila acuminata was more extended than of five related buprestid species. This was caused by a within-brood, or less probably, a between-brood variation in development time in M. acuminata, which was also more variable in adult body…

The morphology of two types of paired deep depressions situated on the ventral side of the pterothorax of Henoticus serratus (Col., Cryptophagidae) were described. The shape of the depressions and surrounding setae indicate that they function as mycangia and that the legs are…

The fauna of wood-living arthropods was studied during two years of succession after tree death in burned and unburned logs at a burned site, and in unburned logs at a clearing and in a forest. Burned spruce logs hosted fewer beetles than unburned logs. Especially bark beetles,…

Breeding populations of the fire-adapted carabid-beetle A. quadripunctatum were found in most of the fifteen investigated burned, uncut forests, but not in any of the fifteen burned clear-cuts, although a few immigrants were found in two of them. The proportion of open-habitat…

Public perceptions of risk and acceptability of forest vegetation management alternatives in Ontario
We examined public perceptions of risk and acceptability for 9 alternatives to controlling forest vegetation in Ontario (N = 2.301) in the fall of 1994. The proportion of respondents indicating whether an alternative was 1) difficult to control, 2) potentially catastrophic, 3) a…
