Tim Bartley, a post-doctoral fellow in the U of G's Department of Integrative Biology. led the research which was conducted in collaboration with the Ministry of Natural Resources and Forestry. "When a species like lake trout responds to the warming of near-shore and surface water by moving deep down into a lake, it's changing the way it feeds, and that cascades into the whole food web," Bartley told Tbnewswatch. The team's work included studying what fish are eating.
