Measuring critical thermal maximum in aquatic ectotherms: A practical guide
Methods in Ecology and Evolution, EarlyView.Abstract Critical thermal limits, commonly quantified as CTmax (maximum) or CTmin (minimum), are core metrics in the thermal biology of aquatic ectotherms. CTmax, in particular, has recently surged in popularity due to its various applications, including understanding and predicting the responses of animals to climate warming.
