The Ecology, Neoichnology and Sedimentology of Siliciclastic Hardground Communities: Implications for Trypanites Assemblages in the Rock Record
DownloadFall 2014
The paleoecology of rocky substrates in the rock record is commonly interpreted based on ichnology (the Trypanites ichnofacies) and is frequently associated with a biotic assemblage with low diversity. However, analyses of two modern, siliclastic, intertidal hardground community at Lion Rock,...

Fall 2023
Global change is altering ecological communities and the food webs they support, reducing food web persistence. While a variety of features likely impact the dynamics of perturbed food webs, the relative importance of intrinsic factors (i.e. characteristics of the food web itself) and extrinsic...

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)...

Fall 2017
Legacy propagule banks of salvaged topsoils are excellent sources of plant propagules for reclamation of mine sites. However, prior studies show that less than 50% of species found in original propagule banks actually establish. We hypothesize that the expression of this legacy propagule bank is...

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...

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 Technical Efficiency of Wildfire Suppression in Alberta, Canada: A Stochastic Frontier Analysis
DownloadFall 2021
Wildfire management agencies are increasingly interested in the efficiency of wildfire suppression as they work to protect human lives and communities from wildfire damages under constrained management budgets. In Alberta, climate change is expected to increase the length of the wildfire season...
