On Thin Ice: Are Lakes Feeling the Heat?

Lakes are warming around the world in response to a changing climate, including warmer water temperatures and shorter ice duration.  Historically Canadian lakes have been highly significant bellwethers, as they represent a northern or southern limit to many freshwater fish species.  This makes Canadian fishes particularly vulnerable to climate change.  Of particular interest are walleye and smallmouth bass.  Walleye, trout, and smallmouth bass are all angler favourites.  But as the feisty smallmouth bass continues its march northward in Canada, it will put populations of trout and walleye at long-term risk.
