Cold-water adapted Brook Trout were historically widely distributed – ranging from northern Quebec to Georgia, and from the Atlantic Ocean to Manitoba in the north, and along the Appalachian ridge in the south. However, studies show that due to factors associated with climate change, such as increased stream temperature and changing water flow, the number of streams containing Brook Trout is declining. Although efforts have been made to protect and restore this cold-water fish at local levels, the extent that temperature increases will vary within and across different streams and the ability of Brook Trout to seek cold-water refugia or adapt to these increasing stream temperatures currently remains unclear. The goal of this project [...]
