Animals must balance a series of costs and benefits while trying to maximize their fitness. For example, an individual may need to choose how much energy to allocate to reproduction versus growth, or how much time to spend on vigilance versus foraging. Their decisions depend on complex...

Modelling Short and Long-term Effects of Soil Cover Depth on Tree Growth and Productivity in Reclaimed Landscapes of Northern Alberta
DownloadSpring 2019
Success in establishing productive upland forests on landforms reconstructed using mining waste mainly depends on the cover materials and depth that determine water and nutrient availability for plant growth while mitigating the potential risks or limitations of the substrate that is being...

Monitoring Ecosystem Dynamics in the Beaufort Sea using Stable Isotopes in Polar Bears (Ursus maritimus) and Ringed Seals (Pusa hispida)
DownloadSpring 2019
Extensive declines in sea ice extent and thickness are occurring within the Arctic and are projected to continue in the future due to amplified polar warming. As a result, community composition and structure are changing within Arctic ecosystems. Animal diets are influenced by accessibility and...

No-analog ecological communities since the last glacial maximum inferred from fossil pollen records for North America
DownloadFall 2019
Given that efforts to reduce greenhouse gas emissions appear to fall short, we need to develop adaptation strategies to mitigate anthropogenic climate change impacts, which may include predicting and managing no-analog ecological communities, for example by selecting suitable species assemblages...

Fall 2019
The rising concentration of anthropogenic heat-trapping gasses has resulted in an energy imbalance in the Earth's climate system. As a consequence of it, an enhanced hydrological cycle and the continuous decline of the ice sheets are expected to increase the freshwater input into the Arctic and...

Parlee, Brenda, Maloney, Elaine, Howlett, Tracy, D'Souza, Amabel
Tracking Change is a six year, SSHRC funded, interdisciplinary research project co-led by Indigenous communities and researcher partners across the Mackenzie, Mekong and Amazon basins. The project foregrounds local and Indigenous knowledge about the impacts of climate change and development on...

The primary objectives of this thesis included contributing to: (i) the state of knowledge on the TDF physiological response to climatic variables; (ii) the understanding of forest resilience through assessing productivity response to temperature and precipitation; and (iii) assessing the...

Fall 2019
The ability of species to adapt to the shifting environmental conditions associated with climate change will be a key determinant of their persistence in the coming decades. This is a challenge already faced by species in the Arctic, where rapid environmental change is well underway. Caribou and...

Rhizosphere microbial response to predicted vegetation shifts and changes in rhizodeposition in boreal forest soils
DownloadFall 2018
The boreal forest is the single largest terrestrial store of carbon on Earth. In Canada’s boreal forest, approximately 23% of these carbon stocks are found in forest floors and 40% within mineral soils. The rhizosphere, soil under the direct influence of plant roots, is a hotspot for microbial...
