Estivation Snonyms
Diapause
A period of suspended development in an insect, other invertebrate, or mammal, often associated with a period of adverse environmental conditions.
Diapause allows insects to survive unfavorable seasons much like estivation.
Torpor
A state of decreased physiological activity in an animal, usually marked by a reduced body temperature and metabolic rate.
Hummingbirds enter a state of torpor at night to conserve energy.
Lethargy
A lack of energy or a state of sluggishness, often resembling or due to biological processes.
The heat induces a lethargy in the animals that is akin to estivation.
Hibernation
A state of inactivity and metabolic depression in endotherms during winter.
Although similar to hibernation, estivation typically occurs in the summer.
Quiescence
A state of quietness or inactivity, used in both ecological and medical contexts.

Inactivity
The quality or state of being inactive; idleness.

Dormancy
A period in which an organism's physical and metabolic activities are temporarily reduced.
Certain seeds also exhibit dormancy until conditions are favorable.
Repose
A state of rest, sleep, or tranquility.
In the repose of estivation, metabolic rates drop significantly.
