Climate change implications for distribution, phenology and conservation of Olive-sided Flycatchers (Contopus cooperi) and Western Wood-Pewees (C. sordidulus) in northwestern North America
DownloadFall 2020
Northwestern North America is predicted to experience some of the world’s greatest human-caused climate change. Understanding the impacts of associated changes will be imperative to the conservation and management of northern-breeding birds. In particular, long distance migrants and aerial...

Effects of clear-cutting and wildfires on succession of ground beetle (Coleoptera: Carabidae) assemblages in western Alberta
DownloadSpring 2019
I studied how carabid beetle assemblages in lodgepole pine stands have responded after clear- cut harvest and wildfires on an actively managed landscape ~20 km south of Hinton, Alberta. This work builds on and expands the focus of a previous study (Niemelä et al. 1993) conducted 23-24 years...

Long-term changes in migratory patterns of elk (Cervus canadensis) in the southern Rocky Mountain Trench of British Columbia, Canada
DownloadSpring 2021
Migration can be described as a round-trip movement between distinct ranges and is thought to be a response to a spatiotemporal variation in resources. Large vertebrate herbivores such as ungulates often migrate to track seasonal variability in high quality forage and reduce predation risk....

Spring 2023
Polar bear conservation faces significant challenges under Arctic warming, especially with respect to habitat loss and the resulting impacts on their seasonal energetic uptake and maintenance. Polar bears rely on sea ice for hunting, mating, denning, and rearing of offspring, and the availability...

Post-fire regeneration of endangered limber pine (Pinus flexilis) at the northern extent of its range
DownloadSpring 2019
Limber pine (Pinus flexilis), an ecologically important species of the montane and subalpine regions of western Canada and the United States, is endangered in Alberta. Limber pine is thought to regenerate following fire, due to its relationship with a bird, the Clark’s nutcracker (Nucifraga...

Sulfur Speciation and Curation Considerations for the Carbonaceous Chondrite Tagish Lake and Other Meteorites
DownloadSpring 2023
Carbonaceous chondrites contain significant abundances of sulfur components such as sulfide, sulfate, elemental sulfur (S0), and organosulfur compounds. These are significant because questions remain regarding the role of S in the origin of life. Chondrites and all other meteorites are out of...

The influence of soil reconstruction materials and targeted fertilization on the regeneration dynamics in boreal upland forest reclamation
DownloadFall 2019
Soil is an essential component supporting the growth and maintenance of terrestrial ecosystems such as forests, providing anchorage, water, and nutrients. In Canada’s boreal forest landscape, surface soils can differ widely in their chemical and physical conditions, ranging from coarse to fine...

What does a detection mean? Spatial and behavioural context improves the use of passive acoustic monitoring for the conservation of a wide-ranging bird
DownloadFall 2021
The culture of ecology is shifting towards collaborative, integrative approaches that use ‘big data’ to solve big problems. Passive acoustic monitoring (PAM) has the potential to play a role in this new paradigm because it uses in-situ autonomous recording units (ARUs) to collect a permanent...
