Lejoly, Justine Daniele Marthe
Exotic species of earthworms are invading North American forests, where native earthworms were extirpated by the last glaciation. The invasion of these ecosystem engineers can alter soil organic matter (SOM) dynamics, carbon (C) persistence, and ecosystem functioning. While the topic has been...

Long-term agronomic and environmental impact of aspen control strategies in the Aspen Parkland
DownloadFall 2010
Since European settlement the Aspen Parkland has been subject to agricultural intensification. This research assessed the agronomic, ecologic and economic impact of native Parkland conversion into tame pasture, by building on a study initiated in 1980 investigating the short-term agronomic...

Roads are a prevalent, ever-increasing form of human disturbance on the landscape. In many places in western North America, energy development has brought human and road disturbance into seasonal winter range areas for migratory elk. In this population, I studied individual habitat selection...

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,...

Nutrient Loading of Aspen, Jack Pine and White Spruce Seedlings for Potential Out-planting in Oil Sands Reclamation
DownloadFall 2012
Low nutrient availability and competing vegetation are some of the issues facing tree crop establishment for land reclamation in the oil sands region. A possible solution to both problems is to load seedlings with nutrients while they are in the nursery. Here, I report on results from a research...

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...

Physics of wastewater flow and pathogen transport processes from a soil-based at-grade effluent treatment system and associated groundwater contamination risks in Alberta, Canada
DownloadSpring 2015
Understanding of wastewater flow and transport processes and treatment effectiveness through the soil-absorption field of soil-based wastewater treatment systems remains a challenge. In addition, Alberta regulators and the on-site wastewater industry wanted to quantify the effectiveness of the...

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...
