Data from: Geothermal stickleback populations prefer cool water despite multigenerational exposure to a warm environment
Given the threat of climate change to biodiversity, a growing number of studies are investigating the potential for organisms to adapt to rising temperatures. Earlier work has predicted that physiological adaptation to climate change will be accompanied by a shift in temperature preferences, but emp...

We found no support for this, as fish from both warm and cold habitats had an average preferred temperature of 13oC. Thus, our results challenge the assumption that there will be a shift in ectotherm temperature preferences in response to climate change. In addition, since warm-habitat fish can persist at relatively high temperatures despite a lower temperature preference, this suggests that preferred temperature alone may be a poor indicator of a population's adaptive potential to a novel thermal environment.
