Evaluating trembling aspen (Populus tremuloides Michx.) seedling stock characteristics in response to drought and out-planting on a reclamation site
DownloadFall 2014
Trembling aspen (Populus tremuloides Michx.) seedlings often display reduced growth, or transplant shock, following out-planting largely due to moisture constraints. This thesis explores the influence of seedling size (root volume), root to stem ratio (RSR) and non-structural carbohydrate (NSC)...

Extraction of Hydrocarbons from Bitumen and Bitumen-containing Process and Process Waste Streams using Supercritical Carbon Dioxide
DownloadSpring 2019
Extractions of hydrocarbons from bitumen and bitumen-containing process and process waste streams generated from surface mined oil sands were conducted using supercritical carbon dioxide (SC-CO2). Dynamic extractions were performed on a bench-scale batch supercritical fluid extraction (SFE)...

Freezing Characteristics of Mine Waste Tailings and their Relation to Unsaturated Soil Properties
DownloadSpring 2018
The study investigated the feasibility of using the soil freezing characteristic curve (SFCC) to estimate the soil water characteristic curve (SWCC) in mine waste tailings as an alternative to traditional SWCC testing. Traditional SWCC tests are challenging and time-consuming to conduct, taking...

This thesis contributes to the development of chronological and geological frameworks for the archaeological record of the mineable oil sands regions in northeastern Alberta, Canada. This area contains a rich pre-European contact archaeological record that has largely been documented through...

Spring 2021
Reclamation of oil sands fluid fine tailings (FFT) is a challenge for mine operators in Alberta because of their high water content and slow self-weight dewatering. Chemical additives, including polymer flocculants, are used by operators as a treatment technology to reduce volumes and increase...

Spring 2013
Industrial development is transforming Alberta's landscapes, with largely unquantified effects on wildlife species. Open-pit mining is occurring on vast expanses, most notably for bitumen but also extensively for coal in a rich seam that traverses the province. Major concerns have developed over...

Fall 2013
This thesis is a multi-modal exploration of the photographer-researcher as a methodological opportunity to gain multiple, collaborative and collective perspectives on living in relation to the Alberta oil sands zone of North America. Using participatory-photography with youth, this thesis is one...

Identifying and analyzing spatial and temporal patterns of lightning-ignited wildfires in Western Canada from 1981-2018.
DownloadSpring 2021
This study looked at the spatial and temporal patterns of lightning-ignited wildfires in Western Canada from 1981 to 2018. Studying patterns of lightning fires over space and time can provide great insight into understanding, highlighting, and quantifying these sequences. This is of great...

Impact of seedling characteristics, outplanting time, and container size on early establishment of aspen (Populus tremuloides) on reclamation sites
DownloadFall 2011
Aspen seedlings often suffer from transplant shock after outplanting. The influence of seedling characteristics and time of outplanting (spring, summer and fall) on field performance was examined on mining reclamation sites. Seedling characteristics were modified by inducing premature bud set...

Impacts of a six year old pipeline right of way on Halimolobos virgata (Nutt.) O.E. Schulz (slender mouse ear cress), native dry mixedgrass prairie uplands, and wetlands
DownloadSpring 2016
Reclamation of native prairie ecosystems is of growing importance as they continue to be impacted by anthropogenic disturbances. Since European settlement, Alberta grasslands have declined by 61 %. Grasslands are agriculturally important, act as a carbon sink, and many species depend upon them....
