Spring 2019
In boreal forests, tree competition has been widely considered as a key process contributing to forest dynamics including driving species turnover, succession and shaping stand-level structure. Understanding how the competition process in boreal forests regulates tree growth and survival is...

Modelling water table depth effects on net ecosystem CO2 exchange of two contrasting forested peatlands – a tropical bog and a boreal fen
DownloadFall 2015
Peatlands have been accumulating carbon (C) in wet soils under shallow water table (WT) over millennia. Increased frequency and intensity of droughts and artificial drainage for promoting agriculture have recently been causing peatland WT depth (WTD) drawdown. This could alter peatland C balance...

Conservation of boreal moth communities in the mixedwood boreal forests of northwestern Alberta: Impacts of green tree retention and slash-burning
DownloadFall 2012
Green tree retention (GTR), which involves leaving dispersed or clustered live trees on harvested stands, is being adopted as an alternative to clear-cutting, and to conserve biodiversity on managed forests. This thesis examines the post-harvest (7-10yrs) recovery of boreal moths following...

Long Term Dynamics And Potential Remediation Of Fine Textured Soils And Ground Water Contaminated With Chlorinated Organic Compounds And Salts
DownloadFall 2019
Contamination of land, water, and air is a widespread concern often associated with anthropogenic activities. Remediation of contaminated sites is necessary to minimize negative impacts on human health and the environment and allow for safe, productive use of land. Although contaminated sites...

Tillage Reversal and Nitrogen Fertilization Affected Greenhouse Gas Emissions and Soil Carbon Stability Differently in a Black Chernozem and a Gray Luvisol
DownloadSpring 2015
Improving soil carbon (C) sequestration through land management practices is of great interest due to concerns over global climate change caused by increased atmospheric greenhouse gas (GHG) concentrations. Soil disturbance by conventional tillage (CT) generally accelerates soil organic carbon...

Spring 2016
Naturalization is a new and promising ecological approach to vegetation management for urban environments. Although there have been years of research focused on areas such as land reclamation, ecological restoration and plant establishment there is a lack of knowledge on how to reintegrate the...

Restoration Of Sagebrush Grassland For Greater Sage Grouse Habitat In Grasslands National Park, Saskatchewan
DownloadFall 2020
Populations of Greater Sage-grouse (Centrocercus urophasianus Bonaparte [Phasianidae]; hereafter Sage-grouse) have been in decline in North America for the last 100 years; since 1988, the Canadian population has declined by 98 %. Initial declines of Sage-grouse populations were likely due to...

Spatiotemporal Patterns and Population Characteristics of Harvested Wolverine (Gulo gulo) in Yukon
DownloadSpring 2017
Wolverines (Gulo gulo) are harvested for fur in Yukon, Canada, but little is known about the sustainability of their harvest. In the absence of population data, harvest management relies on harvest data to assess the efficacy of regulations and harvest sustainability. I examined the...

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,...
