Drought and defoliation-induced alterations to the structure and function of the vascular tissue in trees
DownloadSpring 2019
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...

Effects of burn severity and time since fire on songbird communities in the northern boreal forest
DownloadFall 2018
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 Flammability
DownloadFall 2016
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 change
DownloadSpring 2017
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 comparison of coarse woody debris in post-harvest and post-fire island remnants a decade after disturbance in northern Alberta
DownloadFall 2022
Retention forestry is the practice of retaining forest structure within cut-blocks at harvest sites and is practiced widely throughout the world. Although retention practices are modelled on the propensity for fires to leave behind a variety of biological legacies or structural elements, the...

A range-wide common garden experiment of white spruce indicates population differentiation in drought tolerance traits
DownloadFall 2019
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...
