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 ecology of boreal forest floor microbial communities in relation to environmental factors
DownloadFall 2012
Soil microbial communities in boreal forests are structured by complex interactions among many factors operating simultaneously on large and small spatial scales. Of particular note in the boreal mixedwood, the microbial communities under trembling aspen and white spruce forest floors are...

The effects of subsoil ripping on soil physical properties and soil water dynamics on reconstructed soils at Genesee Prairie Mine, Alberta
DownloadSpring 2014
Surface mining activities have significantly depleted natural tree cover, especially trembling aspen (Populus tremuloides), in the Boreal Forest and Aspen Parkland Natural Regions of Alberta. The natural soil profile is usually destroyed during these mining activities and soil and landscape...

The effects of underplanted white spruce on understory environment and vegetation in aspen-dominated stands of the western boreal forest
DownloadSpring 2012
In the boreal forest of Alberta, Canada, underplanting white spruce (Picea glauca) in aspen (Populus tremuloides) forests attempts to address concerns about "unmixing the mixedwoods". Important ecological differences exist between mixedwood, broadleaf and conifer forests. I studied changes in...

Fall 2011
This thesis presents results from an industrial aspen tree improvement program for Alberta, evaluating a series of provenance, clonal and hybrid field trials. The goals were to (1) investigate geographic patterns of genetic variation in order to delineate breeding regions, (2) to assess the...

The Role of Nutrient and Carbon Reserve Status of Aspen Seedlings in Root-Soil Interactions
DownloadFall 2015
The boreal forest is one of the largest forest ecosystems in the world, covering 14.7 million km2 globally. The Canadian boreal forest has a wealth of natural resources, including coal, timber, and oil; as resource exploration and exploitation has expanded, anthropogenic disturbance in the boreal...

For some geotechnical design projects where soils are exposed to vibration, it becomes necessary to evaluate the strength and deformation characteristics of the soil under existing and/or anticipated vibrations. This thesis presents a summary of an experimental program performed to investigate...

The Short-term Impacts of Aspen Clear-cutting on Upland Groundwater RechargeClear-cutting Impacts on Groundwater Recharge
DownloadSpring 2011
The impacts of aspen clear-cutting on upland groundwater recharge are presented based on two years (2007-2008) of the five year (2005-2009) HEAD2 NSERC-CRD paired-catchment experiment. Research was conducted at the Utikuma Region Study Area (URSA), 370 km north of Edmonton, Alberta, Canada, in...

The influence of the viable but non-culturable (VBNC) state on specific phenotypic traits of Escherichia coli O157:H7 as well as its transport behaviour in porous media was examined in this study. E.coli O157:H7 is a human pathogen capable of entering a VBNC state following exposure to sublethal...

Naturalization is a new and promising ecological approach to vegetation management for urban environments. Although there have been years of research focused on areas such as land reclamation, ecological restoration and plant establishment there is a lack of knowledge on how to reintegrate the...
