Thermal metrics and associated standard errors from chameleons collected from the northernmost established population of Furcifer pardalis in Florida, USA after exposure to seasonal fluctuations in temperature at USDA Wildlife Services National Wildlife Research Center in Gainesville, Florida, from October 2020 to August 2021. CTmin refers to the critical thermal minimum, the temperature at loss of righting response; CTgape refers to the gaping threshold, the temperature at which chameleons gape to thermoregulate; Tbreadth refers to the difference between the CTgape and CTmin; Tpref refers the preferred body temperature, as the average body temperature selected in a thermal gradient.
