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 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...

Shrub encroachment in arctic and alpine tundra: Patterns of expansion and ecosystem impacts.
DownloadFall 2011
With a warming climate, northern ecosystems will face significant ecological changes such as permafrost thaw, increased frequency of forest fires, and shifting ecosystem boundaries including the spread of canopy-forming shrubs into tundra communities. A growing number of observations show...

Space and habitat use of polar bears (Ursus maritimus) in Davis Strait in relation to sea ice conditions and harp seals (Pagophilus groenlandicus)
DownloadFall 2022
Patterns of space use and habitat selection by polar bears (Ursus maritimus) vary among subpopulations where they have been studied. The Davis Strait subpopulation is one of the least researched polar bear subpopulations and their spatial ecology is largely unknown. As an obligate carnivore,...

Spatial and temporal variations of the surface energy balance and ablation on the Belcher Glacier, Devon Island, Nunavut, Canada.
DownloadSpring 2011
In the summer of 2008 (June 2nd – September 19th) detailed measurements of meteorological conditions and glacier surface properties were conducted in the Belcher Glacier catchment (718 km2), Devon Island Ice Cap, Nunavut, Canada. These measurements were used to force and validate a distributed...

Fall 2014
Disruptions to Canada’s pristine northern regions have been steadily increasing due to industrial activities. Many of these impacts lead to destruction or harmful alteration of aquatic ecosystems. Recently, efforts have been made to reduce and offset aquatic habitat impacts through habitat...
