Fall 2020
Threatened woodland caribou (Rangifer tarandus caribou) have experienced large range recessions and population declines across much of Canada’s boreal forest in the last century and have become a major focus of conservation efforts in the region. Habitat management strategies for woodland caribou...

Food availability and grizzly bear (Ursus arctos) selection of post-fire and thinned forests in the mountain national parks of Canada
DownloadFall 2018
Human-caused mortality and habitat loss have led to the extirpation of grizzly bears (Ursus arctos) across much of their North American range. Today, these factors continue to limit extant grizzly bear populations as productive habitats often occur in areas with elevated mortality risk creating...

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...

Getting to the root of the matter: grizzly bears and alpine sweetvetch in west-central Alberta, Canada
DownloadSpring 2012
Wildlife habitat selection is influenced by gender, offspring-dependency, resource availability, and spatiotemporal variation in resource nutrition. In consideration of these factors, this thesis examines alpine sweetvetch (Hedysarum alpinum) root and its relationship to grizzly bears (Ursus...

Dynamics in wildlife populations emerge from the interactions between individuals and their environment. Constraints between individual nutrition and food availability are therefore fundamental to understanding how species adapt to environmental variability and to identify mechanisms controlling...

Fall 2015
Given high levels of human disturbance and projected rates of climate change, many species will be unable to keep pace with their shifting climatic ranges and thus face increased risk of extinction. This research investigated the use of assisted migrations for two rare and range-restricted plant...

Spring 2022
In the boreal biome of North America, large wildfires usually leave behind residual patches of unburned vegetation, termed refugia, which can strongly affect post-fire ecosystem processes. While topographic complexity is a major driver of fire refugia in mountainous terrain, refugia and fire...

Predicting conservation status of North American avian and mammalian scavengers: Implications of geography, life history, behaviour and human disturbance
DownloadFall 2011
Conservation risk is spatially and taxonomically variable, affected by both biological (intrinsic) and environmental (extrinsic) factors. To better understand this variability, I examined how intrinsic and extrinsic factors influenced sub-national patterns of conservation risk in North America...

Regional-scale hydrologic settings buffer black spruce regeneration in the presence of post-fire droughts
DownloadSpring 2024
Lanti-Traikovski, Alexander A.
Climate change is increasing the frequency of droughts and wildfires, reducing tree recruitment, and altering post-fire species composition. In Canada’s western boreal forests, postfire recruitment, particularly of drought-intolerant coniferous species like black spruce, has declined in recent...
