Natural Recovery of Upland Boreal Forest Vegetation on a Hummocky Peat-Mineral Mix Substrate in the Athabasca Oil Sands Region, Alberta
DownloadSpring 2010
This research investigated the natural recovery of upland boreal forest vegetation on a peat-mineral mix substrate in the Athabasca Oil Sands Region, Alberta. Three sites, aged 26 to 34 years, were assessed to determine effects of substrate (pH, electrical conductivity, texture), topography,...

Non-Native Plant Management And Restoration Of Foothills Fescue Grassland In Waterton Lakes National Park, Alberta
DownloadFall 2013
Non-native plants are a formidable barrier to native grassland restoration. Foothills fescue prairie restoration was investigated at three southern Alberta sites through reduction of non-native plant cover by steaming, herbicide and mowing; by increasing native plant cover with transplanting,...

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...

Leafrollers moths are one of the most ecologically and economically important groups of herbivorous insects. These Lepidoptera are an ideal model for exploring the drivers that modulate the processes of diversification over time. This thesis analyzes the evolution of Choristoneura Lederer, a well...

Spring 2012
Reclamation of thousands of limestone quarries around the world is challenged by an extremely limiting environment, including steep slopes, high calcium carbonate substrates with low nutrients and low water holding capacity. These issues were addressed at the Exshaw quarry in the Rocky Mountains...

Reproduction and abundance of the wood frog (Lithobates sylvaticus) in post-harvest variable retention forests
DownloadFall 2017
Many aquatic-breeding amphibians require freshwater habitat for reproduction and terrestrial habitat for refuge, foraging, and overwintering. Variable retention harvesting is a technique where live trees and other forest features are retained during timber harvesting in patterns that emulate...

Spring 2015
A field experiment from 2012 to 2013 at two locations in northeastern Alberta examined the short-term success of different fen revegetation strategies following the removal of infrastructure (road and well-pad) associated with oil extraction. Although all treatments resulted in limited overall...

Snowfall, travel speed, and seismic lines: The effects of snow conditions on wolf movement paths in boreal Alberta
DownloadSpring 2016
In the winter, snow can present a major challenge to large mammals by impeding locomotion, limiting food availability, and imposing additional energetic costs during travel. This thesis examines the effects of snow conditions on the fine-scale movement patterns of grey wolves (Canis lupus) in a...

Lankau, Hedwig Erika Gertraude
I investigated how songbirds respond to seismic lines as the vegetation cover on lines regenerates and how long seismic line effects on songbirds persist. I found that line age was poorly correlated with natural vegetation recovery and that after an initial increase in recovery after 20 years the...
