Physiological plasticity in a successful invader: rapid acclimation to cold occurs only in cool-climate populations of cane toads (Rhinella marina)

Invasive cane toads have been present in Australia and Hawai’i for ~80 years. Toads have invaded sites in each location that are cooler than their native range. These populations have both developed the ability to rapidly acclimate to cold conditions, decreasing their critical minimum temperature over just 12 h.
