in animals, is 'longer-term strategy' the same as hibernation?

Question

this is what my book says: Longer term strategy is to enter a state of reduced activity, called dormancy, during periods of unfavorable conditions such as weather or drought

Answer 1

Each animal species usually has some longer-term strategy other than day-to-day sleeping and eating, so "longer-term" is not anything specific. Bears hibernate, some animals migrate, some estivate, some enter a state of torpor, some just keeping on doing what they do - all of these could be considered longer-term strategies. Estivation looks the term that best describes the type of dormancy described in your quotation.
