Fall 2016
Prairie wetlands provide many important ecosystem services including supporting biodiversity, improving water quality, preventing erosion, recharging groundwater, and attenuating floods. However, more than half of prairie wetlands in North America have been lost, primarily due to drainage for...

Spring 2013
Industrial development is transforming Alberta's landscapes, with largely unquantified effects on wildlife species. Open-pit mining is occurring on vast expanses, most notably for bitumen but also extensively for coal in a rich seam that traverses the province. Major concerns have developed over...

Spring 2014
The worldwide biodiversity crisis has intensified the need to better understand how biodiversity and human disturbance are related. Yet this relationship lacks both consensus in theoretical expectations and consistency in observed empirical patterns. I present one of the largest extent studies...

Rebuilding the boreal: analyzing the replicability of the bacterial community structure and soil functioning of forest floor mineral mix with peat subsoil admixtures
DownloadSpring 2017
Alberta law requires reclamation of lands disturbed by surface mining operations, such as those occurring at the Athabasca Oil Sands Region, however, reclamation rates lag far behind continued disturbance rates. Due to cost, mining companies must make use of the materials on site, of which the...

Reclamation of wetland habitat in the Alberta oil sands: generating assessment targets using boreal marsh vegetation communities
DownloadFall 2010
Thousands of hectares of wetlands are being destroyed by oil sands mining in Alberta, and the industry must undertake wetland reclamation to compensate for these losses. Wetland vegetation has developed at some previously mined sites, however reclamation is thus far exploratory, and limited in...

Semiochemical-based mass trapping of the apple clearwing moth (Synanthedon myopaeformis (Borkhausen)) (Lepidoptera: Sesiidae)
DownloadFall 2011
Semiochemical-based mass trapping was tested against the apple clearwing moth (Synanthedon myopaeformis (Borkhausen)), an invasive apple pest in British Columbia. Two yellow traps baited with apple clearwing moth sex pheromone, (Z,Z)-3,13 octadecadienyl acetate, and Concord grape juice,...

Fall 2018
Benthic marine habitats in Canada have been well-sampled since the annual groundfish survey commenced in 1970. However, trawl surveys cover only non-rocky sediments and many species collected are not identified to lower taxa, leaving large gaps in our understanding of benthic diversity. Sponges...

Fall 2017
Multiple novel and rapidly changing environmental factors (i.e. anthropogenic stressors) are increasingly affecting ecological communities, and their functional roles in ecosystems. Consequently, freshwater biodiversity has declined worldwide; however, the functional impacts of this loss should...

Systematics and diversity of Ichneumonidae, with an emphasis on the taxonomically neglected genus Ophion Fabricius
DownloadFall 2013
Ichneumonidae are the most species-rich family of parasitic Hymenoptera and are important for regulating populations of other arthropods. However, with an estimated 75% of species undescribed, we lack fundamental information about their taxonomy, ecology, and distributions. Using two different...

Use of an Acoustic Location System to Understand Songbird Response to Vegetation Regeneration on Reclaimed Wellsites in the Boreal Forest of Alberta
DownloadFall 2017
Limited information exists on the recovery of different ecosystem components following reclamation of oil and gas wellsites in the boreal forest of Alberta. Songbird response to wellsite reclamation efforts in the boreal forest was previously unexamined, despite the abundance of wellsites,...
