Spring 2018
Lake and sea ice and their snow covers are major components of Earthâs cryosphere and act to strongly modify climatic and biological systems. Both ice types serve as an important habitat for micro-fauna and support macro-fauna and strongly modify the exchange of energy, gases, and momentum...

An evaluation of hitchhiker seedlings with native boreal species as a revegetation tool of industrially disturbed sites in Alberta, Canada
DownloadSpring 2020
Herbaceous forbs hitchhiked, or co-grown, with a woody species, is a solution to establish both native woody and herbaceous species at recently disturbed sites. The broad study objectives were to (1) assess the growth of fireweed hitchhiked with three deciduous woody species and one conifer over...

Anthropogenic influence on the autumn migration of polar bears (Ursus maritimus) in Hudson Bay
DownloadSpring 2022
Migratory species may shift established spatiotemporal patterns in response to anthropogenic impacts, so understanding the energetic consequences of behavioural plasticity may provide insight into how effectively migratory species respond to climate change. I used satellite telemetry to examine...

Arctic Oil, Arctic Change: A Threefold Framework for Evaluating Pressures for Rural Oil and Gas Extraction in Alaska and the Northwest Territories
DownloadFall 2021
Oil has driven migration, community growth, and governance of the last century in the North. Today, as Arctic global warming surpasses 1°C with “profound consequences” (IPCC, 2019) for the North, the relationship between oil and climate change cannot be ignored. In light of this tension, this...

Fall 2016
As resource exploitation and development expands in northern Canada, threats to the ecological integrity of freshwater systems increase. In Canada, developments that could negatively affect aquatic ecosystems require offsetting or compensation measures. As a result of diamond mine development, a...

Spring 2016
The Arctic Ocean sea ice is shifting from a system dominated by thick perennial ice (multiyear ice –MYI) to one dominated by thinner, seasonal ice (first year ice – FYI). The effects of this shift on the bacterial constituents of the Arctic sea ice have been grossly under studied, although it is...

Biogeochemical impacts of glacial meltwaters across a High Arctic watershed (Lake Hazen, Nunavut, Canada)
DownloadFall 2018
Climate change across northern latitudes is fundamentally altering the hydrological cycle there, resulting in increased glacial melt, permafrost thaw and precipitation. Whereas enhanced glacial melt has potentially important implications for water quality and productivity in downstream freshwater...

Building Knowledge and Capacity to Support Healthy Eating and Active Living in the Canadian Arctic
DownloadSpring 2017
This qualitative single exploratory case study design, informed by Critical Social Theory (CST) (Habermas, 1982) and a participatory approach (Freire, 2000), explored how to build knowledge and capacity to support policy interventions that create conditions for healthy eating and active living in...

Spring 2014
ABSTRACT The germination of Clostridium estertheticum, the primary organism responsible for early blown pack spoilage, was investigated. Presence of C. estertheticum in blown packages was confirmed. The effect of pH, temperature and oxygen on germination of spores was established. Germination...
