Spatial and Temporal Variations in Tree Growth, Mortality, and Biodiversity in Alberta Forests
DownloadSpring 2014
Understanding the spatial and temporal variation of tree demographic rates and biodiversity is essential for predicting the dynamics of forest ecosystems and their responses to changing environments. This thesis contributes to that understanding through modeling the long-term change in tree...

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...

Stream Crossings in the Western Boreal Forest: Assessing Impacts and Prioritizing Restoration for Native Freshwater Fishes
DownloadFall 2015
Growing anthropogenic development in response to rising demands for natural resources is a major concern for freshwater fish, particularly in resource rich regions such as Canada’s boreal forest. Expanding networks of industrial resource roads has led to the installation of hundreds of thousands...

The Biogeography of Ground Beetles (Coleoptera: Carabidae) on the Islands of Lac la Ronge, Saskatchewan, Canada
DownloadFall 2015
Islands offer unusual opportunities for studying theoretical concepts in ecology. I studied the role of island size and isolation in structuring assemblages of ground beetles (Coleoptera: Carabidae) on the islands and adjacent mainland of Lac la Ronge, Saskatchewan, Canada. Carabid beetles were...

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 potential of forest floor transfer for the reclamation of boreal forest understory plant communities
DownloadFall 2011
We examined a direct forest floor transfer reclamation technique to establish a native boreal forest understory plant community on a reclamation site at a coal mine. Forest floor material was salvaged from an aspen-dominated (Populus tremuloides Michx.) donor forest at two depths (15 and 40 cm)...
