Natural and anthropogenic inputs of arsenic and selenium to the environment in the Athabasca Bituminous Sands Region
DownloadSpring 2019
Industrial development of the Athabasca Bituminous Sands (ABS) in northern Alberta, Canada, has raised concerns that emissions of arsenic and selenium to the surrounding landscape and waterbodies have been increasing over time. To test this hypothesis, a comprehensive study of arsenic and...

Natural Recovery of Upland Boreal Forest Vegetation on a Hummocky Peat-Mineral Mix Substrate in the Athabasca Oil Sands Region, Alberta
DownloadSpring 2010
This research investigated the natural recovery of upland boreal forest vegetation on a peat-mineral mix substrate in the Athabasca Oil Sands Region, Alberta. Three sites, aged 26 to 34 years, were assessed to determine effects of substrate (pH, electrical conductivity, texture), topography,...

Spring 2013
A major barrier to reclamation after oil sands mining is lack of commercially available, diverse native plant seeds and propagules for revegetation. Potential of LFH (forest floor material) developed on coarse textured soil for establishing native plants and how salvage, placement and storage...

Oil Sands Reclamation With Woody Debris Using LFH Mineral Soil Mix And Peat Mineral Soil Mix Cover Soils: Impacts On Select Soil And Vegetation Properties
DownloadFall 2014
Prior to mining oil sands, soil is salvaged for reclamation and forest stands are harvested for their merchantable timber. Harvest operations leave large amounts of residual woody debris, which has been historically burned or mulched. Woody debris has significant ecological effects and can be...

Many northern Alberta soils have a thick forest floor that houses the majority of soil biogeochemical processes and biological interactions. Microarthropods dominate the faunal communities in these soils, and oribatid mites are the key detritivores that initiate litter decomposition and maintain...

Fall 2020
Oil sands mining is a significant disturbance in the Canadian boreal forest. One objective for reclamation after mining is to create a self-sustaining ecosystem, which includes establishing a native plant community. For this thesis, study one evaluates the different plant assembly mechanisms,...

Productivity and carbon accumulation potential of transferred biofilms in reclaimed oil sands-affected wetlands
DownloadSpring 2011
Biofilms are significant contributors to primary production, nutrient cycling, bio-stabilization and the food web of wetland ecosystems. Photoautotrophic biomass (PB) and primary production (PP) were determined for biofilms exposed to various treatments and materials in wetlands near Fort...

Fall 2015
The recent open pit mining for oil sands in the Athabasca Oil Sands Region (AOSR), northern Alberta has created an unprecedented industrial scale disturbance whose ecological consequences is not well understood, and requires intensive investigation. This study focused on the temporal dynamics of...

The Importance and Influence of the Human Dimensions in Grizzly Bear (Ursus arctos) Conservation
DownloadFall 2018
Conservation practitioners increasingly recognize the importance and influence of the social context in conservation outcomes. From local stories to newsprint articles, the language we use, the stories we tell, and the interactions we have with wildlife species can influence human relationships...

The role of microtopography in vegetation colonization and early forest development on mine reclamation sites
DownloadSpring 2023
Microsite heterogeneity is an important variable that drives biodiversity in forests. Current forest reclamation practices often do not incorporate site heterogeneity in their practices which might pose a challenge to the reclamation goals of restoring disturbed sites to resilient and sustainable...
