Extract

Although it may be convenient to distinguish them, hibernation, aestivation, and diapause are in reality different manifestations of the same phenomenon which we may call diapause. The symptoms of this condition are a marked depression of metabolism and quiescence; and the remote causes as suggested by observation are cold, heat, drought and (or) certain nutritional peculiarities such as richness or dryness of food. These factors may act singly or in combination, with different factors dominant in different cases.
