Lighting, fire is the dominant natural disturbance of the western mixedwood boreal forest of North America. We quantified the independent effects of weather and forest composition oil lightning fire initiation (a detected and recorded fire start) patterns in Alberta, Canada, to demonstrate how...

Volney, W.J.A., Langor, D. W., Jacobs, J. M., Work, T. T., Spence, J. R.
The Canadian insect fauna is too inadequately Understood to support well-informed assessments about its conservation status: however, the foregoing collection of synthetic papers illustrates potential threats front industrial forestry. Loss of forest species and dramatic changes in forest insect...

Abstract: Fire has been the dominant disturbance in boreal America since the Pleistocene, resulting in a spatial mosaic in which the most fire occurs in the continental northwest. Spatial variation in snowshoe hare ( Lepus americanus) density reflects the fire mosaic. Because fire initiates...

Lightning and fire characteristics within the Northwest Territories (NWT) jurisdiction of the Mackenzie Basin between 1994 and 1999 are examined using data from the lightning detection network operating in the NWT and from the national Large Fire Database maintained by the Canadian Forest...

An empirical scheme for predicting the meteorological conditions that lead to summer forest fire severity for Canada using the multivariate singular value decomposition (SVD) has been developed for the 1953-2007 period. The levels and sources of predictive skill have been estimated using a...

Saproxylic insect assemblages inhabiting dead wood in Canadian forests are highly diverse and variable but quite poorly understood. Adequate assessment of these assemblages poses significant challenges with respect to sampling, taxonomy, and analysis. Their assessment is nonetheless critical to...

Abstract: Early establishment of white spruce (Picea glauca) in mixedwood boreal forest stands following fire was examined at several times-since-fire (1-, 2-, 4-, 6-, 14-years). Abiotic and biotic conditions in the stands were assessed at two scales, tree plot (5 in x 5 in) and microsite (1 m x...
