Many hikers in Southern Alberta head to the trails in spring equipped with bear spray, singing or saying hey bear, woah bear, to warn the animal they're around the corner. Elders and knowledge keepers from Stoney Nakoda Nations have their own approach, and lessons to share when it comes to co-existence.

Scientists are studying the diets of the oceans’ top predators as they change in response to their environments. This is because how much and what they eat can affect how ecosystems function.

Climate change is affecting all aspects of our land, and also what flies in our sky. Bird migration is changing as average temperatures rise. So what does that mean for our bird species?

The number of dogs testing positive for tick-borne illnesses has nearly doubled this year, says a Nova Scotia veterinarian. Jeff Goodall, the owner and a veterinarian at Sunnyview Animal Care, said the problems go beyond Lyme disease. Anaplasmosis is also a concern.

Researchers will be stepping up their efforts to track chronic wasting disease in Saskatchewan's north.

Scientists say climate change appears to be a factor making Florida and other parts of the U.S. welcoming to non-native mosquitoes.

With ice declining, bowhead whales of the Pacific Arctic choose to stay longer in the waters up north. A change in migration patterns could affect the bowheads' health and safety, as well as the hunters' access to the subsistence resource.

Researchers at Memorial University, Ocean Networks Canada and the University of Victoria found the urchins, living as deep as 400 metres below, were expanding their populations into shallower water at an average rate of 3.5 metres per year as ocean warming reduces oxygen levels and food sources at lower depths.

Research shows Beavers are relatively new to the Seward Peninsula and push farther north as climate change occurs.

Vancouver Island is known for its predatory wildlife, such as black bears, coastal wolves and cougars. Many towns and villages sit in areas with high populations of predatory wildlife, making interactions with humans often inevitable, unless effective coexistence management is in place.
