Spring 2014
The worldwide biodiversity crisis has intensified the need to better understand how biodiversity and human disturbance are related. Yet this relationship lacks both consensus in theoretical expectations and consistency in observed empirical patterns. I present one of the largest extent studies...

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...

Limited impacts of extensive human land use on dominance, specialization, and biotic homogenization in boreal plant communities
Download2015-01-01
Mayor, S. J., Boutin, S., He, F., Cahill, J. F.
Background Niche theory predicts that human disturbance should influence the assembly of communities, favouring functionally homogeneous communities dominated by few but widespread generalists. The decline and loss of specialists leaves communities with species that are functionally more similar....

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...

Movies of River Water Tracers in ANHA4 NEMO Simulation
2024-01-01
Online passive tracers for river runoff input from the ANHA4 ocean model. EPM015 is was run with Dai and Trenberth for river runoff, and EPM151 was run with A-HYPE for river runoff. Both have a forced atmosphere from CGRF. The difference between the two tracers can also be seen, where positive...

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....

Young, T. Kue, Chatwood, Susan, Bjerregaard, Peter
"This paper describes the elements involved in observing health in circumpolar regions, the status of current observation systems, and gaps within the monitoring networks. The aim is to provide a starting point for discussion of the role that health monitoring might play in developing Arctic...
