Potential impacts of climate change on the distributions of several common and rare freshwater fishes in Canada
ABSTRACT Climate change will ultimately affect the supply and quality of freshwater lakes and rivers throughout the world. This study examines the potential impacts of climate change on freshwater fish distributions in Canada. Climate normals data (means from 1961 to 1990) from Environment Canada we...
