Disturbance, habitat variability and biodiversity of a boreal carabid (Coleoptera: Carabidae) fauna 15 years after variable retention harvest
DownloadFall 2018
Species diversity patterns and the processes that drive them are a central focus of modern ecology. Although the spatial effects of habitat variation and disturbance on aggregate metrics like diversity and abundance have received considerable attention at local scales, ecologists have virtually...

Diverting Resources to Turn on Resistance: Influences of Biotic and Abiotic Stresses on Aspen Seedlings
DownloadFall 2012
The interactions between biotic and abiotic stresses and their influence on plant reserves in non-photosynthetic tissues (i.e., roots and stems) and the role of plant reserves in tree defenses are poorly understood. Aspen seedlings grown under different conditions (light, fertilizer) were grouped...

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...

Fall 2023
Western Canadian forests have been subject to periods of drought stress over the last three decades, resulting in growth reductions, dieback, and increased wildfires in the context of climate change. To contribute to adaptive forest management, this study compares drought vulnerabilities of eight...

Spring 2014
Peat mineral soil mix has been the predominant cover soil used in Athabasca oil sands reclamation. Use of LFH mineral soil mix (forest litter layers and underlying mineral soil) has recently been mandated by regulatory approvals. Effectiveness of these cover soil types to provide diverse, native...

Early Stages Of Calcareous Soil Reclamation Along The TMX-Anchor Loop Pipeline In Jasper National Park
DownloadFall 2010
Research assessed early stages of calcareous soil reclamation along the TMX-Anchor Loop pipeline through Jasper National Park. Calcareous soils are low in nutrients and highly prone to erosion after disturbances. Four sites were established in each of five calcareous soils, and divided into three...

Re-establishment of appropriate vegetation communities is an important aspect of successful forest reclamation as they contribute to various ecosystem functions. In my research I explore how different coversoil materials (salvaged forest floor (FFM) and peat material), their placement depths, and...

Fall 2015
Aspen is a widespread forest tree of high economic and ecological importance in western Canada. The species has also been subject to tree improvement efforts over the past two decades to increase productivity of the forested land base. Successful selection and breeding programs rely on both...

Ecological Response of Atmospheric Nitrogen Deposition on Reconstructed Soils in the Athabasca Oil Sands Region
DownloadSpring 2012
Oil and gas extraction in the Athabasca oil sands region has increased anthropogenic nitrogen (N) emissions over the past two decades. This study quantified atmospheric N deposition and assessed the potential implications of increased N deposition in aspen (Populus tremuloides Michx.) and jack...
