Drought and defoliation-induced alterations to the structure and function of the vascular tissue in treesDownload
Observations of tree dieback and mortality from climate change-induced drought has been documented across the world, however the mechanisms of tree mortality are not fully understood. Infestations of insect pests may also contribute to the process of drought-induced dieback. Tree physiological...
Wildfire shapes the boreal ecosystem in western Canada and thereby enhances and diminishes important breeding habitat for many songbird species. Two aspects of wildfire, burn severity and time since fire, fundamentally alter the forest structure that songbirds use. The objectives of this study...
A Proposed Experimental Methodology for Assessing the Effects of Biophysical Properties and Energy Content on Live Fuel FlammabilityDownload
The effectiveness of fire management tactics and safety of firefighters strongly depend on the reliability of fire behaviour predictions that is currently limited by a lack of understanding of the flammability of live fuel. Until now fire modeling has been primarily based on the flammability of...
A century of landscape change in the southern Rocky Mountains and Foothills of Alberta: Using historical photography to quantify ecological changeDownload
Throughout the Rocky Mountain regions of North America fire regimes have been altered towards longer fire return intervals in the 20th century as compared to the 18th and 19th centuries; this has been accompanied by losses of grassland and open canopy woodlands due to encroachment by closed...
A range-wide common garden experiment of white spruce indicates population differentiation in drought tolerance traitsDownload
In western regions of the Canadian boreal forest, mean annual temperature has increased by 1.5 to 2.5 °C, significantly exceeding the mean global temperature increase. Climate conditions have also become drier and together these climate trends have induced widespread growth reductions, dieback...
A simulation/optimization system for modelling timber and old forest under stochastic fire disturbanceDownload
Stochastic wildfire disturbance contributes to uncertainty in forest management planning. In this study, a system composed of an optimizing forest estate model nested within a Monte Carlo simulation model of stand replacing fires is used to investigate the impact stochastic fire may have on the...
