Fall 2023
Western Canadian forests have been subject to periods of drought stress over the last three decades, resulting in growth reductions, dieback, and increased wildfires in the context of climate change. To contribute to adaptive forest management, this study compares drought vulnerabilities of eight...

Enhanced prediction of extreme fire weather conditions in spring using the Hot-Dry-Windy Index in Alberta, Canada
DownloadSpring 2023
Fire weather indices used to forecast fire behaviour provide valuable information for wildland fire prevention, preparedness, and suppression. The primary index used in Canada, the Fire Weather Index System, provides qualitative fuel moisture and fire behaviour indices. However, the indices used...

Evaluating trembling aspen (Populus tremuloides Michx.) seedling stock characteristics in response to drought and out-planting on a reclamation site
DownloadFall 2014
Trembling aspen (Populus tremuloides Michx.) seedlings often display reduced growth, or transplant shock, following out-planting largely due to moisture constraints. This thesis explores the influence of seedling size (root volume), root to stem ratio (RSR) and non-structural carbohydrate (NSC)...

Factors affecting the detectability and eastern distribution of grizzly bears in Alberta, Canada
DownloadFall 2013
Effective and adaptive conservation of a species requires knowledge of trend in abundance and distribution. Monitoring species that are highly mobile, cryptic, and occurring at low densities is especially challenging. This research investigates the local factors affecting the detectability of...

Fall 2016
Humans are the major cause of forest fires in the spring in Alberta, and have resulted in major property damage in both the Flat Top Complex fires in 2011 and the Fort McMurray fire in 2016. Fire occurrence prediction (FOP) models can help predict when and where fires can be expected in order to...

Gastropod diversity in the boreal mixedwood forest of northern Alberta - variation among forest types and response to partial harvesting
DownloadFall 2010
Terrestrial gastropods are important decomposers, herbivores, and prey items in forest systems and constitute a poorly understood element of forest biodiversity in Canada. I studied gastropod assemblages in relation to forest cover type and in response to variable retention harvesting in the...

Spring 2024
Trembling aspen (Populus tremuloides Michx.) is a dioecious clonal tree species with broad distribution in North America. In dioecious species, sexes are predicted to perform differently, based on the principle of allocation and the energy costs associated with reproduction. Aspen reproduce...

Habitat Use in Undisturbed Forest and the Effect of Variable Retention Harvesting on Pollinator Assemblages (Apoidea, Syrphidae) in the Boreal Forest of Alberta
DownloadSpring 2019
While pollination in agricultural areas has been well studied, pollinators in forests have received much less attention, particularly in the boreal forest. Bees, especially native bees, and hoverflies are the two most important groups of pollinators providing crucial ecological and economical...

Identifying and analyzing spatial and temporal patterns of lightning-ignited wildfires in Western Canada from 1981-2018.
DownloadSpring 2021
This study looked at the spatial and temporal patterns of lightning-ignited wildfires in Western Canada from 1981 to 2018. Studying patterns of lightning fires over space and time can provide great insight into understanding, highlighting, and quantifying these sequences. This is of great...

Identifying historical climate-growth limitations of white spruce (Picea glauca) populations across North America
DownloadSpring 2021
Climate change may cause reduced forest productivity and higher tree mortality due to water deficits that result from increased evapotranspiration. Such limitations may occur in some areas of the North American boreal forest, where precipitation is low and warming trends are high. This thesis...
