To forecast the impact of climate warming on cold-water fishes, thermal tolerance trials were conducted on six populations of brook trout from Cape Race, Newfoundland, Canada. Of these, three were outcrossed to assess the effect of hybridization. Although differences were found, there was little variation among populations in how they responded to thermal stress.
