Aestivation (Latin: aestas (summer); also spelled estivation in American English) is a state of animal dormancy, similar to hibernation, although taking place in the summer rather than the winter. Aestivation is characterized by inactivity and a lowered metabolic rate, that is entered in response to high temperatures and arid conditions. [ 1 ]
During winter dormancy, plant metabolism comes to a virtual standstill, due in part to low temperatures that slow chemical activity. [1]Dormancy is a period in an organism's life cycle when growth, development, and (in animals) physical activity are temporarily stopped.

[15] A good example of the differences between these two types of hibernation can be seen in ...
Some of the park's African animals, such as white rhinos and yellow mongooses, were born and raised on site rather than in warmer climes so are more used to British winters. The park said all of ...
