A dataset of acclimation potential of terrestrial, freshwater and marine ectotherms across latitudes collected from the literature spanning the time period 1960 to 2015 with the aim to test the importance of physiological acclimation as a mechanism to buffer species against climate warming.
The projected rate of environmental warming is used to calculate how many years and generations acclimation capacity will afford each species before it will exceed its thermal maximum. Acclimation capacity, generation time, latitudinal range extent and projected rate of warming are then combined into an index of vulnerability. This data together with critical thermal maxima of the ectotherms are presented here.

|Quality:||All data was checked by eye. Generation time was only available for some species.|
|Lineage:||We first conducted long-term experiments of thermal limit acclimation focused on marine polar regions, and then combined these with an extensive range of empirical estimates of acclimation capacity in terrestrial, freshwater and marine ectotherms. We use these data in combination with future climate projections to quantify the added time that acclimation can lend species, potentially improving the chances of evolutionary rescue under realistic warming scenarios. Given the rate of climate warming and the degree to which the species' heat tolerance adjusts to increasingly warmer acclimation temperatures, we calculate how much time acclimation will provide each species in our dataset before environmental temperatures exceed their adjusted, tolerable thermal limits. We project warming tolerance in units of years, as well as number of generations for those species for which generation times were available. The full methodology is detailed in Morley et al. (2018).|
