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...

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...

Specialist predators with a limited diet may be less adaptable to environmental change than generalists, which consume a diversity of prey. As the climate changes, ecological homogenization is occurring, where generalist species outcompete specialists, reducing ecosystem complexity. In Arctic...

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...

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...
