Exploring the Impacts of Environmental Stressors on the Beaufort Sea Ecosystem	Central and Arctic 10/05/2010
From the production and distribution of microscopic algae to the health of belugas and the feeding preferences of bowhead whales, Fisheries and Oceans Canada (DFO) scientists have been probing the Beaufort Sea in Canada's Western Arctic to explore the cumulative impacts of environmental stressors on this complex ecosystem.

Probing Lake Ontario's Nearshore Ecosystem	Central and Arctic 02/11/2009
In recent years a new aquatic invasive species (AIS), commonly known as the bloody red shrimp, has found its way from Eastern Europe (Azov, Black and Caspian seas) to the nearshore waters of Lake Ontario where it may compete with larval and juvenile fish for food.

Molecular Genetics Unravel the Mysteries of Marine Mammal Populations

Central and Arctic 19/10/2009

Every spring, beluga whales that winter in open water areas of eastern Hudson Strait and adjacent waters migrate through the Hudson Strait into Hudson Bay. They spend the summer in coastal estuaries and come fall they return to their wintering areas. For communities in Northern Quebec, the spring and fall migrations are a traditional time to hunt beluga. Migration adds to the challenge of distinguishing one population or stock from another, as does the tendency of marine mammals to form groups based on family, age, sex or social relationships.

Killer Whales In The Eastern Arctic	Central and Arctic 05/10/2009
Mention killer whales to most Canadians and they tend to think of the resident and migratory pods of the west coast. So well known have they become by locals and tourists alike that a whole tour industry has been set up around their yearly appearance.

Exploring the Impacts of Global Warming on Arctic Marine Mammals: Traditional Inuit Knowledge Complements Scientific Research	Central and Arctic 22/09/2009
As climate change melts Arctic sea ice, altering the habitat of marine mammals and other wildlife, scientists are learning invaluable information about the changes underway from those who are among the first to observe them - Inuit elders and hunters who, along with their ancestors, have relied on the land for centuries.

Water Parks	Central and Arctic 14/09/2009
When most Canadians think of their parks, they tend to think of them in terms of the national or provincial parks they visit in the summer. Or as conservation areas that must be protected at all costs. What these parks all have in common is that they are terrestrial. We can see, touch, and experience them first-hand relatively easily.

The Bowhead Whale: Where Does It Live? What Does It Eat?	Central and Arctic 22/06/2009
Did you know that bowhead whales live exclusively in the Arctic? They were heavily hunted in the 19th and early 20th century and have been classified as threatened since 2005 by the Committee on the Status of Endangered Wildlife in Canada.

Assessing the risks: Aquatic invasive species research at Fisheries and Oceans Canada	Central and Arctic 25/05/2009
No doubt you've heard about the intruders in Canada's waters. Many aquatic species, once unknown in Canada, are here - and they are impossible to ignore.
