From species to genes: ecological and evolutionary mechanisms structuring diversity in space and time
DownloadFall 2021
My Ph.D. thesis addresses three foundational questions in conservation biology: i) what is biodiversity and how is it best measured? ii) how does variation in habitat configuration, habitat composition, and environmental conditions affect emergent patterns of species diversity? and iii) how do...

This thesis studied the efficacy of sprinklers for fuel hazard reduction to prevent wildfires. Fire management’s response capacity to suppress wildfires is increasingly becoming overwhelmed because of climate change and its effects on fire regimes. Sprinkler-watering can change fuel moisture...

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...

Genetic adaptation of aspen populations to spring risk environments: a novel remote sensing approach
DownloadSpring 2010
This study investigates geographic patterns of genetic variation in aspen spring phenology to understanding how tree population adapts to climatically risk environments. These finding suggest rules to guide seed transfer between regions. I use a classical common garden experiment to reveal...

Genetic mapping and physiological characterization of water-use efficiency in barley (Hordeum vulgare L.) on the Canadian Prairies
DownloadFall 2011
Temporal or seasonal water deficit is one of the major factors limiting crop yield on the Canadian Prairies. Empirical knowledge suggests that carbon isotope discrimination (Δ13C), through its negative relationship with water-use efficiency (WUE), is a good index for selecting crop varieties...

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...

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...
