Canada Warbler (Cardellina canadensis) response to vegetation structure on regenerating seismic lines
DownloadFall 2021
Seismic lines have an extensive footprint in Canada’s western boreal forest and cause habitat removal, degradation, and fragmentation. Changes in practices and regulations for operations and reclamation have led to an accumulation of legacy seismic lines that exist within a range of seral states....

Characterization of Soil Spatial Heterogeneity and Improvement of Capping Materials for Oil Sands Mine Reclamation
DownloadFall 2018
Surface mining in the Athabasca Oil Sands Region (AOSR), Alberta, Canada creates a large-scale ecosystem disturbance requiring ‘land reclamation’. Mining approvals require that land reclamation returns the sites to an equivalent land capability class, but this goal has proven challenging to...

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...

Evaluating remote sensing covariates for understanding habitat selection by boreal forest birds
DownloadFall 2023
Boreal forests are changing in response to climate change and shifts in disturbance regimes. Statistical models that link distribution, abundance, and community structure to select environmental variables have been used to understand how birds respond to these changes. However, model performance...

Fall 2009
Kura clover (Trifolium ambiguum) is a perennial legume species that has been found to have exceptional persistence in the United States, Australia and New Zealand. There are two challenges that impede the incorporation of Kura clover into pasture mixtures in Alberta. The first is the lack of...

Reliable population density estimates are critical for ecological research and species management but can be difficult to obtain. Sampling methods like noninvasive genetic sampling and remote camera traps, combined with appropriate statistical models, provide opportunities to estimate density...

Spring 2022
In the boreal biome of North America, large wildfires usually leave behind residual patches of unburned vegetation, termed refugia, which can strongly affect post-fire ecosystem processes. While topographic complexity is a major driver of fire refugia in mountainous terrain, refugia and fire...

Resiliency of boreal forest tree species on a reclaimed oil sands mine and natural forest stands in northeastern Alberta
DownloadSpring 2019
Disturbances in the boreal forest are common, so the species that comprise these forests must be resilient to them. This research examines the resiliency, here defined as the regeneration of boreal tree species following disturbance on both reclaimed and natural sites. The suckering response of...

Rhizosphere microbial response to predicted vegetation shifts and changes in rhizodeposition in boreal forest soils
DownloadFall 2018
The boreal forest is the single largest terrestrial store of carbon on Earth. In Canada’s boreal forest, approximately 23% of these carbon stocks are found in forest floors and 40% within mineral soils. The rhizosphere, soil under the direct influence of plant roots, is a hotspot for microbial...
