The Introduction of Cipangopaludina chinensis and Trophic Effects of Sympatric Freshwater Invaders in Southern Alberta Reservoirs
DownloadSpring 2023
At present, one of the most pervasive risks to freshwater ecosystems are invasive species. Invasive species are among the leading antagonists to global biodiversity, since they can out-compete or predate on native species which leads to changes of the structure of food webs and alteration of...

An Investigation of Potential Weed Management Practices and Multivariate Assessment Parameters for Alberta's Oil Sands Reclamation Efforts
DownloadSpring 2018
Reclamation efforts that promote the re-establishment of native tree and plant communities subsequent of large-scale oil sands mining land disturbances are crucial in restoring natural ecosystems. It is important that reclamation procedures capable of facilitating the establishment of native...

A comparison of coarse woody debris in post-harvest and post-fire island remnants a decade after disturbance in northern Alberta
DownloadFall 2022
Retention forestry is the practice of retaining forest structure within cut-blocks at harvest sites and is practiced widely throughout the world. Although retention practices are modelled on the propensity for fires to leave behind a variety of biological legacies or structural elements, the...

Local-Scale Drivers of Spatial Patterns and Demographic Rates of Conifer Species in a Forest Chronosequence in Coastal British Columbia
DownloadSpring 2017
Growth, mortality and recruitment are the fundamental demographic processes driving changes in forest structure and dynamics. Rapid changes observed in many forests globally have imposed serious threats to ecosystem services such as carbon sequestration, biodiversity and hydrology, emphasizing...

Native tree seedling interactions with variations in edaphic properties in upland boreal forest restoration
DownloadSpring 2015
The boreal forest is a vast circumpolar ecosystem covering approximately 11 % of terrestrial land globally. The Canadian boreal forest is rich in natural resources such as lumber, minerals, and oil, and therefore is heavily managed by humans in some regions. Surface mining for oil sands deposits...

Genetic variation in lodgepole pine and interior spruce: adaptation to climate and implications for seed transfer
DownloadSpring 2014
This thesis investigates genetic variation of two commercially important conifers in western Canada, interior spruce and lodgepole pine. The goals were to quantify genetic diversity and geographic structure, to describe multitrait adaptation to local climates, and to use this information for the...
