Mike Shouldice of Rankin Inlet reports this summer’s caribou migration patterns have shifted, with far fewer animals passing through traditional routes and fewer visible signs such as hanging skins.

On more than 30 occasions and across four oceans, orcas have attempted to share their prey with people, potentially to develop relationships with humans, researchers have found.

A new study reports that Atlantic salmon exposed to the anti-anxiety drug clobazam during migration became bolder, passing through hydropower dams faster, though this behavior might increase predation risk later.
