Poikilothermic (cold-blooded) animals are clearly dependent on the environmental temperature, as their metabolic processes are directly influenced by the external temperature: If it is cold, these processes are slower and the successive phases of the annual cycle are retarded; when it is hot, they speed up.

Typically, temperature elevation accelerates poikilothermic growth until a species-specific thermal maximum is attained, beyond which growth and/or survival is depressed (Kinne 1970, Hochachka & Somero 2002).
