Building Resilient Communities: Planning for Natural Hazards Risks in Small and Mid-Sized Municipalities in Alberta, Canada
DownloadFall 2019
Land-use planning is a vital discipline in the discourse on climate change and disaster risk reduction because of its role as a long-term non-structural mitigation measure. Planners can gather and analyze evidence-based data to influence decision-makers on how to minimize vulnerability via a...

Drought and defoliation-induced alterations to the structure and function of the vascular tissue in trees
DownloadSpring 2019
Observations of tree dieback and mortality from climate change-induced drought has been documented across the world, however the mechanisms of tree mortality are not fully understood. Infestations of insect pests may also contribute to the process of drought-induced dieback. Tree physiological...

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...

Ecosystem sensitivity to variation in precipitation and defoliation across grasslands of Alberta
DownloadSpring 2022
Climate models project a greater likelihood of increases in precipitation variability and droughts over the Great Plains of North America. Drought’s interactions with other co-occurring factors, such as grazing, can lead to substantial and long-lasting changes to ecosystem goods and services. In...

Effect of drought and defoliation on plant growth, symbiotic nitrogen fixation, soil nitrogen availability and soil microbial dynamics in forage legumes
DownloadSpring 2024
Forage legumes play a crucial role in agriculture due to their symbiotic nitrogen fixation (SNF) ability by forming a symbiotic relationship with soil rhizobia, providing high-quality forage to livestock and improving soil health. The changing global climate is predicted to increase the frequency...

Extracellular enzyme activity, greenhouse gas emissions and soil microbial communities responses to drought and defoliation in northern temperate grasslands
DownloadFall 2023
Grassland ecosystems cover more than 40% of the global land area and provide many ecological goods and services, therefore, it is important to sustain these terrestrial ecosystems. One of the ecological services they provide is their potential to act as a carbon (C) sink. However, northern...

Genome-wide association study of plant physiological parameters, yield, and nitrogen fixation-related traits in soybean under drought stress
DownloadFall 2022
Kombala Liyanage, Dilrukshi KD
Soybean is one of the world’s leading legume crops. It fixes atmospheric nitrogen with the symbiotic relationship of rhizobia bacteria that inhabit root nodules. The global population is expected to exceed 9.7 billion by 2050, resulting in increased food demand, particularly for protein. In...

Mixing tree species and density management to reduce drought susceptibility in coastal plantation forests of British Columbia
DownloadFall 2024
The coastal forests of British Columbia have been experiencing longer and more intense droughts in recent years. To evaluate the effects of species composition and density on drought sensitivity, a study was conducted in a Douglas-fir:western redcedar plantation established in 1992, in the...

Modelling the impacts of climate change on blue and green water interchange, crop yields, and virtual water trade under drought and post-drought conditions in Nelson River Basin
DownloadFall 2023
The unfolding climate change crisis poses a growing challenge to water and food security, and yet the reliability of the global breadbaskets and their relation with water resources in the future is poorly understood. The global breadbaskets are defined as key production regions for food grains...

Fall 2019
The primary objectives of this thesis included contributing to: (i) the state of knowledge on the TDF physiological response to climatic variables; (ii) the understanding of forest resilience through assessing productivity response to temperature and precipitation; and (iii) assessing the...
