 In contrast to these fast changes, anole's adaptability to temperature changes has traditionally been considered relatively minor.Nevertheless, when Puerto Rican crested anoles in Florida (where introduced in the 1970s) were compared to the original, native population in Puerto Rico, it was discovered that the former had become adapted to colder temperatures, by about 3 °C (5.4 °F).An even faster adaption was observed in Carolina anoles from Texas during the unusually cold winter of 2013–2014.
