Abstract
The ability of coldwater species and populations to respond to the predicted temperature increases associated with climate change will largely depend on existing adaptive potential within and among populations. Southern inland populations of Lake Trout Salvelinus namaycush are broadly characterized by two ecotypes (small and large bodied) which differ in their trophic ecology, life history traits, and body size. This study investigates population-specific differences in thermal performance (growth, temperature tolerance, and temperature preference) and whether the differences were consistent between ecotypes. It further explores the role of acclimation temperature on growth and thermal performance in two representative ecotypic populations.
