Effects of Climate Change on Lake Ice Freeze Up Across the Northern Hemisphere: Historical Patterns and Future Predictions
Shifts in freeze up dates signal climatic change. We examined nine lakes in the Great Lakes region to forecast freeze up dates into the future. We also examined 75 lakes around the Northern Hemisphere to understand how and ...
Variability in the Foraging Patterns of Polar Bears (Ursus Maritimus) in the Canadian High Arctic and Foxe Basin
Ongoing climate warming is projected to cause further declines in sea ice across the Arctic; as a result the foraging ecology of marine species will change. This thesis aimed to investigate the ecological patterns associated ...
Polar Bear (Ursus Maritimus) Foraging Ecology in the Western Canadian Arctic
Climate change has led to abrupt declines in sea ice over the past three decades. Polar bears (Ursus maritimus) rely on sea ice as their primary habitat to hunt marine mammal prey. Due to their position at the top of the ...
Long-Term Changes of Hypolimnetic Dissolved Oxygen and Phytoplankton Community Composition in a Large Lake, Lake Simcoe, Ontario and Revisit Dissolved Oxygen Profile Models for Lakes in Central Ontario
Long-term changes in volume-weighted hypolimnetic dissolved oxygen (VWHDO) and phytoplankton community composition were examined as important water quality indicator in Lake Simcoe, a large freshwater lake with impacts by ...
Global Stressors, Regional Impacts: How Will Climate Change Influence Future Cisco (Coregonus Artedii) Distributions in Ontario? Are Sport Fish Mercury Levels Affected By Climate?
As global air temperatures rise and precipitation events fluctuate as a result of climate change, environmental conditions for many freshwater fish are expected to change. Fish are particularly sensitive to climate change ...
Walleye Out of the Frying Pan and into the Fire: How Will Climate Change Influence Ontario Walleye (Sander Vitreus) and Small Mouth Bass (Micropterus Dolomien) Populations? Do Small Mouth Bass Invasions Negatively Influence Walleye Abundance?
Climate change will impact freshwater fish communities in Ontario. Warmwater species are expanding their ranges northward while cool and coldwater species are expected to shift or decline under the current rates of warming. ...
