Development of a Comprehensive Nitrogen Budget to Increase Nitrogen Use Efficiency and Reduce Nitrogen Losses in Semi-Arid Southern Alberta
DownloadSpring 2024
Synthetic nitrogen (N) fertilizer has increased crop yields, but crop nitrogen use efficiency (NUE) is low. The N fertilizer not taken up by the crop is subject to nitrate leaching, ammonia volatilization, and denitrification losses, contributing to declining air and water quality, ozone layer...

Development of a Genetic Algorithm Model for a Multiple-Objective Forest Harvesting and Zonation Problem
DownloadFall 2014
Most of the forested lands in North America are managed for multiple objectives and forest management plans are designed in a manner to obtain or maintain sustainable forest management certification. One strategy for achieving some of these goals is forest zonation, which allows for different...

Development of an Extraction Method for Estimating Phytoaccessible Fractions of Bromacil and Tebuthiuron
DownloadFall 2022
Bromacil and tebuthiuron are herbicides used from the 1960s to 1990s on industrial sites to control vegetation. Approximately 61,750 sites are considered contaminated when comparing total herbicide concentrations (estimated by 99 percent methanol extraction) against Alberta’s remediation...

Development Of Shrub And Lichen-Dominated Biocrust Propagation And Establishment Techniques For Reclamation In Northern Environments
DownloadSpring 2022
Resource exploration and extraction in the arctic causes long lasting disturbances as natural recovery is a long and slow process in the north. With three Canadian diamond mines expected to close in the next fifteen years, many hectares of land will require revegetating. Research conducted in the...

Displacement and Mortality of Birds by High Voltage Transmission Lines in the Canadian Dry Mixed Prairie
DownloadFall 2018
Canadian grasslands are continuing to experience loss in habitat and degradation in quality due to agricultural expansion and fragmentation from roads, pipelines, and transmission lines. Today, only 43% of Canadian mixed grass prairie remains. This loss and fragmentation has led to a decline in...

Distribution and breeding ecology of boreal and northern saw-whet owls in the Boreal forests of Alberta, Canada
DownloadSpring 2018
The boreal forest is an ecologically dynamic region with a long history of natural disturbances. These dynamics now run at a different and more rapid pace in Alberta because of land-use change, forestry, and developments in the energy industry. Although boreal owls Aegolius funereus and northern...

Disturbance Effects of Oil Sands Exploration Practices on Coarse-textured Soils and Populus tremuloides Michx. Regeneration
DownloadSpring 2018
Oils sands exploration (OSE) sites associated with in situ oil sands development are required to evaluate and delineate oil resources. Once these sites are cleared and disturbed for exploration, they can result in habitat disturbance and fragmentation, invasion of weed species, changes to surface...
