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 The database provides a listing of fire research publications relevant to Alaska and a venue for sharing unpublished agency reports and works in progress that are not normally found in the published literature.

Populus tremuloides Michx. postfire stand dynamics in the northern boreal-cordilleran ecoclimatic region of central Yukon Territory, Canada

Strong
Postfire vegetation development among 8-185-year-old stand was assessed based on 100 releves from the northern boreal-cordilleran ecoclimatic region (61-63ºN) in the central Yukon Territory, Canada. Vegetation sampling included only stands thought to have originated from…

Response of the shortgrass steppe plant community to fire

Scheintaub, Derner, Kelly, Knapp
Fire is an important driver of ecological pattern and process in grasslands worldwide, although its role in semi-arid systems is less well known. We used published studies and new experimental research to 1) provide a synthesis of existing knowledge of fire in the semi-arid…

Salvage logging in the boreal and cordilleran forests of Canada: integrating industrial and ecological concerns in management plans

Saint-Germain, Greene
Fire has been part of the North American boreal and cordilleran ecosystems for thousands of years. Because fire and harvesting compete directly for the same wood supply, and provinces have, within the last few decades, tended to reach their annual allowable cut, salvage logging…

Advantages of a two band EVI calculated from solar and photosynthetically active radiation fluxes

Rocha, Shaver
A two band Enhanced Vegetation Index (EVI2) without the blue band reflectance has recently been developed as a proxy for the phenology, quantity, and activity of vegetation. We compared the ability of EVI2 and the more commonly used Normalized Difference Vegetation Index (NDVI)…

Agroforestry and the search for alternatives to slash-and-burn cultivation: from technological optimism to a political economy of deforestation

Pollini
Launched in 1994, the Alternatives to Slash-and-Burn Programme is a multidisciplinary collaborative research effort aimed at addressing the issue of deforestation. This article analyzes the genesis and the history of this research effort and the causes of its successes and…

Reproductive success of the black-backed woodpecker (Picoides arcticus) in burned boreal forests: are burns source habitats?

Nappi, Drapeau
The black-backed woodpecker (Picoides arcticus) is considered a fire specialist throughout its breeding range. Given its high abundance in recent burns, it has been hypothesized that post-fire forests are source habitats for this species. We conducted a 3-year post-fire study to…

Mimicking the natural doping of migrant sandpipers in sedentary quails: effects of dietary n-3 fatty acids on muscle membranes and PPAR expression

Nagahuedi, Popesku, Trudeau, Weber
Wild semipalmated sandpipers (Calidris pusilla) eat n-3 fatty acids to prime their muscles for long migrations. Sedentary bobwhite quails (Colinus virginianus) were used as a model to investigate the mechanisms for this natural doping. Our goal was to characterize the…

The spatial and temporal distribution of crop residue burning in the contiguous United States

McCarty, Korontzi, Justice, Loboda
Burning crop residue before and/or after harvest is a common farming practice however; there is no baseline estimate for cropland burned area in the contiguous U.S. (CONUS). We present the results of a study, using five years of remotely sensed satellite data to map the location…

Post-fire natural regeneration of young stands on clearcut and partial-cut and uncut sites of boreal mixedwoods

Li, Dang, Ambebe
Boreal mixedwoods are an important element and the most productive forest type in the Canadian boreal forests. However, they experience frequent disturbances. In order to better understand the responses of boreal mixedwoods to different combinations of anthropogenic and natural…

The use of historical range and variability (HRV) in landscape management

Keane, Hessburg, Landres, Swanson
This paper examines the past, present, and future use of the concept of historical range and variability (HRV) in land management. The history, central concepts, benefits, and limitations of HRV are presented along with a discussion on the value of HRV in a changing world with…

Bobwhite quail (Colinus virginianus) hatchlings track the direction of human gaze

Jaime, Lopez, Lickliter
Gaze following allows individuals to detect the locus of attention of both conspecifics and other species. However, little is known about how this ability develops. We explored the emergence of bobwhite quail hatchlings' ability to track human gaze by assessing their avoidance…

Multi-parameter renewal processes and simulation of forest fires

Ivanoff
The concept of the renewal property is extended to processes indexed by a multidimensional time parameter. The definition given includes not only partial sum processes, but also Poisson processes and many other point processes whose jump points are not totally ordered. Various…

Response of six boreal tree species to stand replacing fire and clearcutting

Ilisson, Chen
Emulation of natural disturbance processes and their effects is important to maintain the structure and composition of managed forests. To examine whether logging and fire have different effects on natural regeneration, we studied the recruitment of six common boreal tree…

Origin of the lichen-spruce woodland in the closed-crown forest zone of eastern Canada

Girard, Payette, Gagnon
Aim We investigate the timing and factors responsible for the transformation of closed-crown forests into lichen-spruce woodlands.Location The study area extends between 70º and 72º W in the closed-crown forest zone from its southern limit near 47º30' N to its northern limit at…

Predicting the long-term yield trajectory of black spruce stands using time since fire

Garet, Pothier, Bouchard
Yield curves are traditionally constructed with mean age of dominant trees as the temporal variable. However. When tree longevity is shorter than the average period of time between two successive disturbances. Mean age of dominant trees becomes a doubtful temporal variable in…

Modeling containment of large wildfires using generalized linear mixed-model analysis

Finney, Grenfell, McHugh
Billions of dollars are spent annually in the United States to contain large wildland fires, but the factors contributing to suppression success remain poorly understood. We used a regression model (generalized linear mixed-model) to model containment probability of individual…

Emulating natural disturbances: the role of silviculture in creating even-aged and complex structures in the black spruce boreal forest of eastern North America

Fenton, Simard, Bergeron
Ecosystem-based forest management is based on the principle of emulating regional natural disturbance regimes with forest management. An interesting area for a case study of the potential of ecosystem-based forest management is the boreal forest of north-western Quebec and north…

Tree mortality following boreal forest fires reveals scale-dependant interactions between community structure and fire intensity

Dalziel, Perera
Fire disturbance patterns influence forest communities at a range of spatial scales. Forest community structure may also influence fire disturbance patterns, because tree species vary in their fuel value and in their tolerance to fire damage. However, the influence of community…

A stochastic forest fire growth model

Boychuk, Braun, Kulperger, Krougly, Stanford
We consider a stochastic fire growth model, with the aim of predicting the behaviour of large forest fires. Such a model can describe not only average growth, but also the variability of the growth. Implementing such a model in a computing environment allows one to obtain…
