Development Of Shrub And Lichen-Dominated Biocrust Propagation And Establishment Techniques For Reclamation In Northern Environments
DownloadSpring 2022
Resource exploration and extraction in the arctic causes long lasting disturbances as natural recovery is a long and slow process in the north. With three Canadian diamond mines expected to close in the next fifteen years, many hectares of land will require revegetating. Research conducted in the...

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...

The net exchange of carbon greenhouse gases with high Arctic terrestrial and aquatic ecosystems
DownloadSpring 2015
Accelerated climate warming of Canada’s sparsely vegetated high Arctic has resulted in rapid environmental changes including loss of glacial ice, permafrost thaw, decreased snow cover and changing plant communities. These responses are causing mostly unknown changes to the natural cycling of the...

Spring 2016
Reclamation of northern disturbances is of increasing importance as industrial activities and associated infrastructure expands to accommodate growing human reliance on world ecosystems. Bryophytes are recognized as ecologically essential to northern ecosystems and effectively promoting their...

A Functional Approach Reveals Zooplankton Responses to Environmental Change in Mountain Lakes
DownloadFall 2017
Concern is increasing over the future cumulative impacts of multiple stressors on freshwater biodiversity and ecosystem function, especially in alpine environments where climatic warming increases with elevation. Here, consideration of individual species traits enables translation of changes in...

Evaluating Fish Habitat Compensation in the Canadian Arctic: Stream Habitat Attributes and Macroinvertebrate Assemblages
DownloadFall 2014
Resource development is expanding in Canada, particularly in the Arctic. In Canada, damage to stream ecosystems as a result of development requires habitat restoration or compensation measures. A compensation project, focused on improving ecosystem connectivity and aquatic habitat for fish within...

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...

The impact of recreational activities on an alpine vascular plant community in the Canadian Rockies
DownloadFall 2010
Alpine tundra is notorious for its fragility and slow recovery following disturbance. Tourism is increasing in alpine areas, creating the need to improve our understanding of the impacts of recreation in these ecosystems. This study examined the impacts of hiking and off-highway vehicle use on...

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...

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...
