Abstract

Environments vary enormously in the thermal challenge they impose on the organisms that live in them. Some of these changes occur over very small temporal and spatial scales, and animals respond to these changes by acute modulations of their behaviour and physiology. More chronic changes in thermal environments, such as seasonal changes and latitudinal changes across the globe, require different responses. Three types of response have been recognized in both exothermic and endothermic vertebrates. These are termed acclimation, acclimatization and adaptive responses.
