Influence of Environmental and Site Factors and Biotic Interactions on Vegetation Development Following Surface Mine Reclamation Using Coversoil Salvaged From Forest Sites
DownloadSpring 2017
Industrial activities such as surface mining are responsible for disturbing large areas of forest land. Reclamation methods must facilitate the development of soil, of a diverse natural understory plant community, and of a tree canopy. In my thesis research, I examined the response of vegetation...

Growth of understory spruce following mountain pine beetle attack and recalibration and validation of the Mixedwood Growth Model for black spruce
DownloadFall 2018
Effective forest management requires reliable growth and yield models and adequate information on changes in the forest resulting from climate change, insect outbreak and competition from neighboring trees. Growth responses of white spruce (Picea glauca (Moench) Voss) and black spruce (Picea...

Fish harvest and replacement of top piscivorous predators in aquatic food webs: implications for restoration and fisheries management
DownloadSpring 2013
The potential for walleye (<i>Sander vitreus</i>) restoration at Lac la Biche, Alberta, Canada is a social-ecological question that requires understanding of changes to ecosystem integrity and historical fidelity resulting from disturbance. This study explored variability in fisheries-induced...

Assessment of soil capping for phosphogypsum stack reclamation at Fort Saskatchewan, Alberta
DownloadFall 2009
Phosphogypsum (PG), an acidic byproduct of phosphoric acid production during phosphate fertilizer manufacturing, is commonly stacked on the facilities and capped with soil at decommissioning. The research evaluated soil capping depth (0, 8, 15, 30, 46, 91 cm) effects on response of five seeded...

Interactions among Nitrogen Input, Nitrification Inhibition, Edaphic and Environmental Conditions on N2O Fluxes and associated Biological Processes in Central Alberta Soils
DownloadFall 2020
Increasing atmospheric concentration of nitrous oxide (N2O) emissions due to intensified human activities is of concern, as N2O is not only a precursor for stratospheric ozone destruction but also an important greenhouse gas. Agriculture accounted for about 82% of the anthropogenic N2O production...

EFFECTS OF CLIMATE CHANGE, VEGETATION AND ROADS ON CARIBOU DISTRIBUTION IN WESTERN NORTH-AMERICA
DownloadFall 2017
Caribou (Rangifer tarandus) are a vital component of the cultural history and contemporary existence of First Nations and northern communities. However, caribou habitat is increasingly threatened by cumulative effects of climate change and land-use pressures from human settlement, forestry, and...

A simulation/optimization system for modelling timber and old forest under stochastic fire disturbance
DownloadSpring 2011
Stochastic wildfire disturbance contributes to uncertainty in forest management planning. In this study, a system composed of an optimizing forest estate model nested within a Monte Carlo simulation model of stand replacing fires is used to investigate the impact stochastic fire may have on the...

Spring 2010
This research determined if woody debris amendments facilitate land reclamation after oil sands mining. Specifically, it assessed if woody debris affects vegetation cover and richness, woody species survival and abundance, soil nutrients, temperature and water, microbial biomass carbon and...
