Grizzly bears sightings are on the rise on Vancouver Island, and experts have a few theories as to why this is happening.

When Kodiak Island's elderberries started ripening earlier, its iconic bears changed their diet. It's another ecological shift amid climate change, scientists say.

On an Alaskan island, one of nature’s greatest spectacles is shutting down, as brown bears abandon fish in favor of a surprising alternative.

About 10 grizzly bears have been living at the community dump in Aklavik, N.W.T., this summer. Arey said a couple of bears were destroyed earlier this summer, but said more may need to be killed as residents are still seeing the bears coming into the community near homes.

Only one, located in British Columbia's Thompson River, is considered stable.

Federal fisheries experts paint devastating picture of the challenges facing Pacific salmon and point to climate change as the main culprit.

The number of chinook salmon that reached the Whitehorse fish ladder this year hit a 40-year low, and it's not clear why. Just 282 chinook passed through the fish ladder this year, compared to 690 last year. "We did see some large pre-spawn mortality die-offs in a tributary of the Yukon River — the Koyukuk in Alaska. This was for summer chum, and not chinook — but we expect that that higher water temperature also affected the chinook migrating through."
