Habitat use by fluvial Arctic Grayling (Thymallus arcticus) in mountain streams of the Little Nahanni watershed, Northwest Territories
DownloadFall 2020
Northern aquatic ecosystems face increasing pressures from climate change and natural resource development, raising conservation concerns for species in these vast and remote regions. Arctic Grayling (Thymallus arcticus) have a Holarctic distribution and are a sensitive freshwater fish that...

River runoff plays a very important role in the Arctic Ocean. The Arctic Ocean accounts for around 1% of the total world ocean volume, but receives around 11% of the worlds river runoff. In addition, the Arctic Ocean is a β ocean, where stratification is primarily determined by salinity as...

Individual variation in on-ice movement dynamics and site fidelity of western Hudson Bay polar bears
DownloadFall 2023
Individual variation affects fundamental aspects of ecology and behaviour in many species. Individuals vary in sex, age, reproductive status, and personality, which can be compared between individuals (inter-individual) or within individuals (intra-individual). In this dissertation, I tested...

Intergenerational resilience in Aklavik, NT – exploring conceptualizations, variables, and change across generations
DownloadFall 2012
I explore resilience qualitatively and quantitatively with youth, adults, and elders in Aklavik, Northwest Territories, Canada. Using focus groups, semi-structured and follow-up interviews, the research questions were: How is resilience defined in Gwich’in and Inuvialuit cultures? What themes...

Spring 2018
Climate change will continue to affect the Arctic more intensely than other biomes. These changes can have dramatic effects on biotic interactions that influence the functioning of these systems, including plant-herbivore interactions. Invertebrate herbivores strongly depend on external...

Fall 2018
The Arctic and the North Atlantic Oceans are experiencing multiple stresses such as loss of sea ice, changing atmospheric patterns, increasing wind energy at the ocean surface and larger freshwater discharge to coastal regions. To address how the marine system may respond to these stresses I...

Numerical modelling of the Arctic and North Atlantic exchanges with NEMO: Focus on freshwater and dynamics
DownloadFall 2018
The Arctic is currently undergoing significant changes due to increasing anthropogenic greenhouse gases causing atmospheric warming. The impact of this warming is clearly visible in the Arctic: reduced sea-ice cover, enhanced land-ice melting, increased frequency of extreme weather, etc....

Spring 2015
Polar bears (Ursus maritimus) enter a period of intensified feeding in the spring, which allows for the accumulation of energy stores critical to surviving the open water season. Study on polar bear predation has been limited by sample size and spatial extent, and hypotheses on the demographic...

Fall 2014
I investigated the population and landscape genetics of Arctic Grayling (Thymallus arcticus) distributed throughout several connected river systems in Alberta, Canada. Broad- and fine-scale population structure was examined by genotyping nine microsatellite loci in 1,116 Arctic Grayling captured...
