EFFECTS OF CLIMATE CHANGE, VEGETATION AND ROADS ON CARIBOU DISTRIBUTION IN WESTERN NORTH-AMERICA
DownloadFall 2017
Caribou (Rangifer tarandus) are a vital component of the cultural history and contemporary existence of First Nations and northern communities. However, caribou habitat is increasingly threatened by cumulative effects of climate change and land-use pressures from human settlement, forestry, and...

Effects of community structure on aboveground net primary productivity (aNPP), leaf area index (LAI) and light use efficiency (LUE) in a boreal mixedwood forest of central Alberta, Canada.
DownloadFall 2018
Management practices, such as the use of herbicides to reduce abundance of deciduous and herbaceous vegetation can have dramatic influences on community structure and composition in regenerating boreal ecosystems. The vertical structure of boreal stands includes different functional groups:...

Effects of Elevated Root Zone pH and NaCl on the Stress Responses and Recovery of Selected Boreal Forest Tree Species
DownloadFall 2020
Prior to surface mining of bitumen in the Athabasca oil sands region of northern Alberta, all vegetation and soil is removed from the boreal forests where the mines are located. Revegetation following mine closures is challenging, partly due to high soil pH and elevated Na levels present in many...

Effects of energy development on habitat use of an avian peatland specialist and generalist at multiple spatial scales
DownloadFall 2020
With the persistent demand for petroleum energy products, the energy development footprint in northern Alberta continues to expand, perforating habitat in the boreal forest. Modern in situ, or below ground, bitumen extraction techniques have broadened the extent of accessible reserves and are...

Effects of Enhanced Non-segregated Tailings, Root Hypoxia, and Salinity on the Growth of Commonly Used Oil Sands Reclamation Plant Species and Halophytes
DownloadFall 2023
In Alberta, Canada, oil sands mining activities have disturbed many boreal forest habitats and produced large amounts of tailings. Recently, a novel oil sands tailings management technology of the enhanced non-segregated tailings (eNST) has been developed, which uses polymers to accelerate...

Effects of Ericoid Mycorrhizal Fungi on Growth and Salt Tolerance of Blueberry (Vaccinium myrtilloides), Lingonberry (Vaccinium vitis-idaea), and Labrador tea (Rhododendron groenlandicum): Implications for Oil Sands Reclamation
DownloadFall 2019
Oil sands mining can have negative environmental impacts in the boreal forest region of northern Alberta, Canada. The Government of Alberta requires the companies to reclaim disturbed lands after mine sites are closed. The initial steps in oil sands mining operations involve the removal of forest...

Effects of linear anthropogenic corridors on insect pollinator movement and diversity, and understory shrub fruit production in the boreal forest of northeastern Alberta
DownloadSpring 2021
Fragmentation of habitats is a primary concern in the conservation of global biodiversity. Anthropogenic linear disturbances, such as roads, trails, and power lines, are a major source of habitat fragmentation worldwide. In Alberta’s boreal forest, a common, pervasive type of disturbance is...

Effects of long-term nitrogen and sulfur deposition on soil microbial communities and soil properties in the Athabasca oil sands region in northern Alberta, Canada
DownloadFall 2016
Intensified oil sands activities have resulted in elevated levels of nitrogen (N) and sulfur (S) deposition in the mixedwood boreal forest in the Athabasca oil sands region (AOSR) of northern Alberta, Canada. The deposition of N and S can affect the surrounding ecosystem and it is important to...
