Wetland loss in Alberta: Identifying successes, barriers, and unintended outcomes of public policy
DownloadSpring 2013
The province of Alberta adopted a wetland policy in 1993 to manage wetlands in the central and southern regions of the province. Despite a stated commitment to review the policy every five years, to date, no policy evaluation has been conducted. Consequently, little is known about whether wetland...

Tracking a better way to count wildlife: testing the Formozov-Malyshev-Pereleshin (FMP) formula in the Kalahari
DownloadSpring 2020
The science of conservation biology is about conserving species. To do so often requires information about population sizes. Great efforts have been devoted to counting animals, the diverse means by which are invariably taxa and environment-limited. Faced with a biodiversity crisis,...

The use of peat applications and Carex aquatilis for peatland reclamation on post mined landscapes in northern Alberta, Canada
DownloadFall 2018
I investigated peatland reclamation factors in a wetland built on a former open-pit oil sands mine in northern Alberta, Canada. The primary research objectives were to investigate the persistence of peat placed in a newly constructed wetland, the survival and establishment of Carex aquatilis...

Fall 2011
In the Rocky Mountain foothills of Alberta, Canada, activities of the forestry and energy sectors have resulted in the installation of tens of thousands of stream-crossing structures. In fifteen Athabasca River basins I found that culverts impeded upstream movements of non-sportfish species...

The Increasing Prevalence of Smaller Fish in Highly Exploited Fisheries: Concerns, Diagnosis and Management Solutions.
DownloadSpring 2010
A decline in the size of fish within a population is concerning. Large-sized fish are ecologically important and valued for social and economic reasons. Following widespread collapses from angling overharvest, the densities of Walleyes Sander vitreus in Alberta’s lakes increased rapidly with...

Sustaining the Recovery of Lake Sturgeon (Acipenser fulvescens) in the North Saskatchewan River of Alberta
DownloadSpring 2016
Nearly all Lake Sturgeon (Acipenser fulvescens) populations across North America have experienced losses to historic abundances estimated to be > 99%. This species is especially vulnerable to overharvest, habitat degradation, river fragmentation from dams, and is slow to recover due to life...

Productivity and carbon accumulation potential of transferred biofilms in reclaimed oil sands-affected wetlands
DownloadSpring 2011
Biofilms are significant contributors to primary production, nutrient cycling, bio-stabilization and the food web of wetland ecosystems. Photoautotrophic biomass (PB) and primary production (PP) were determined for biofilms exposed to various treatments and materials in wetlands near Fort...

Fall 2021
Species interactions are thought to underlie the stability of ecosystems, and nowhere is studying such interactions more important than the rapidly changing Arctic. The foraging behaviour of generalist consumers is influenced by the abundance of multiple resources, and generalists are thought to...

Fall 2020
Acorus calamus is an important medicinal plant in many cultures around the world. This plant’s recorded history reaches as far back as 287 BCE, where its main uses were water purification and as a medicinal “cure-all”. In part one, I examined the history of A. calamus, its applications in the...

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...
