Rivers and Choc analysis description from Does global change increase the risk of maladaptation of Atlantic salmon migration through joint modifications of river temperature and discharge?
In freshwater ecosystems, water temperature and discharge are two intrinsically associated triggers of key events in the life cycle of aquatic organisms such as the migration of diadromous fishes. However, global changes have already profoundly altered the thermal and hydrological regimes of rivers,...
