The Ordering of Things: Narrative Geographies of Bloody Falls and the Central Canadian Arctic
(2015-12-16)
This study examines the geographies of the Bloody Falls massacre story, an account of a massacre of a group of Inuit by a group of Dene allegedly witnessed by explorer Samuel Hearne along the Coppermine River in July 1771. ...
High-Latitude Responses of Diatom and Chironomid Assemblages to Regional Climate Changes and Other Environmental Stressors
(2015-07-03)
High-latitude freshwater ecosystems are amongst the most vulnerable to climate change impacts. However, the response to warming is rarely straightforward and may be modulated by local or regional factors, producing variability ...
From Genes to Genomes: Local Adaptation and Adaptive Potential in Two Arctic Seabirds
By investigating the mechanisms underlying the evolution and the maintenance of local adaptations we can help predict how species will adapt to future environmental change. In this thesis I investigate local adaptation and ...
A comparative paleolimnological assessment of the influences of early Arctic population groups on freshwater ecosystems from southern Baffin Island, Nunavut
(2011-10-04)
Recent paleolimnological research in the eastern Canadian high Arctic on the ecological impact of the Thule c.1000-1500 AD has documented the influence of prehistoric anthropogenic activities. Six lake and pond sites ...
A paleolimnological assessment of recent environmental changes in lakes of the western Canadian Arctic
(2013-04-17)
The freshwater ecosystems in the western Canadian Arctic are threatened by multiple and interacting stressors, as high-latitude regions are undergoing rapid change resulting from climate warming and other human-related ...
Seasonal Controls on Litter and Soil Carbon and Nutrient Cycling in Arctic Tundra Ecosystems and Potential Impacts of Climate Change
(2016-01-29)
Climate change is leading to warmer temperatures and greater snowfall in Arctic regions. Microbial decomposition activities are strongly regulated by temperature, and therefore climate warming is projected to enhance decay ...
Dumpcano: Waste Management and Environmental Justice in Iqaluit
(2016-05-02)
On May 20, 2014, the Iqaluit dump lit itself on fire, burning for 178 days. ‘Dumpcano’ as it was nicknamed, cannot be seen in isolation: Iqaluit is surrounded by unremediated dump sites, left behind from both the Canadian ...
Impacts of Enhanced Temperature and Snow Deposition on Senescence Date, Vegetation Cover, and CO2 Exchange in a Canadian High Arctic Mesic Ecosystem
Arctic regions are expected to experience an increase in both temperature and precipitation over the coming decades, which is likely to impact vegetation dynamics and greenhouse gas exchange. To test this response, an ...
Modelling Biophysical Variables and Carbon Dioxide Exchange in Arctic Tundra Landscapes using High Spatial Resolution Remote Sensing Data
(2013-01-04)
Vegetation community patterns and processes are indicators and integrators of climate. Recently, scientists have shown that climate change is most pronounced in circumpolar regions. Arctic ecosystems have traditionally ...
Remote Sensing of Vegetation Change Across a Latitudinal Gradient in the Canadian Arctic
(2016-07-04)
Global air surface temperatures and precipitation have increased over the last several decades resulting in a trend of greening across the Circumpolar Arctic. The spatial variability of warming and the inherent effects on ...
