Offsetting approved harmful anthropogenic impacts in the 21st century – Insights into global offsetting practices, habitat banking as an alternative offsetting mechanism and application of habitat enhancement in northern boreal lake systems
DownloadFall 2022
Land-use change via human development is a major driver of biodiversity and habitat area loss and ecosystem function impairment. To reduce these impacts, billions of dollars are spent on environmental offsets, aimed to compensate for authorized negative impacts. Studies evaluating offset project...

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...

On the origin of virtual wetlands by means of computer aided selection or the preservation of favoured places in the struggle for functional wetlands
DownloadSpring 2010
To aid in reclamation planning for the Genesee Coal Mine in Alberta, I qualified the pre-mined state of wetlands and measured land use and land cover (LULC) change between 1982 and 2007. A generalized linear model (GLM) was developed to explain the presence of wetlands on the pre-mined...

Optimal use of resources: classic foraging theory, satisficing and smart foraging – modelling foraging behaviors of elk
DownloadSpring 2010
It is generally accepted that the Marginal Value Theorem (MVT) describes optimal foraging strategies. Some research findings, however, indicate that in natural conditions foragers not always behave according to the MVT. To address this inconsistency, in a series of computer simulations, I...

West-central, Alberta is subject to a growing number of resource extraction activities such as forestry that change ecosystem components and their structure. This area is important for the grizzly bear (Ursus arctos horribilis) population, which is considered to be a threatened species in Alberta...

Fall 2017
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...

Over-expression of PIP2;5 aquaporin in a Populus tremula×P.alba clone and its effects on plant responses to low root temperature and osmotic stress
DownloadFall 2015
This dissertation describes the studies that examined: 1. Production of transgenic poplar over-expressing the poplar aquaporin PIP2;5 and 2. Comparison of the physiological properties of a transgenic poplar with the wild-type under different stress conditions including a) short-term low root...

Overstory and understory dynamics of whitebark pine (Pinus albicaulis) ecosystems of northwestern British Columbia
DownloadFall 2010
Whitebark pine (Pinus albicaulis) is declining across its range due to disturbances such as mountain pine beetle and white pine blister rust. In this thesis, I assess the response and vulnerability of whitebark pine ecosystems to multiple stressors and disturbances at the northern edge of...
