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...

Monitoring Ecosystem Dynamics in the Beaufort Sea using Stable Isotopes in Polar Bears (Ursus maritimus) and Ringed Seals (Pusa hispida)
DownloadSpring 2019
Extensive declines in sea ice extent and thickness are occurring within the Arctic and are projected to continue in the future due to amplified polar warming. As a result, community composition and structure are changing within Arctic ecosystems. Animal diets are influenced by accessibility and...

Spring 2015
Polar bears (Ursus maritimus) are an apex predator of the Arctic marine food web and vulnerable to changes in sea ice because various aspects of their existence depend on this dynamic platform. Arctic sea ice extent and thickness have declined, and been particularly low since the first record...

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...

Prairie plant species at risk in Southern Alberta: identification of critical habitat at the microsite level for Halimolobos virgata (Nutt.) O.E. Schulz and determination of set back distance between pipeline disturbance and Halimolobos virgata and Cryptantha minima Rydb.
DownloadFall 2011
Little is known about the effect disturbances such as pipelines can have on prairie plant species at risk and their critical habitat in Alberta. Halimolobos virgata appears to be a ruderal, disturbance evolved species that occupies a unique rim niche. This habitat around the rim of depressional...

The glacial geology and geomorphology of central Banks Island record the extent and dynamics of the northwest Laurentide Ice Sheet (LIS) during Late Wisconsinan glaciation. Additional stratigraphic exposures document Mid Quaternary environmental changes. Detailed mapping and a new chronology...

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...

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...
