What function does Estivation serve? Hibernation. Hibernation and its hot weather equivalent, estivation, are periods of inactivity and seclusion, usually accompanied by cooler than normal body temperature, which enable animals to pass through seasons when food is scarce or inaccessible .
What is the purpose of the estivation?
Estivation is one form of dormancy that some animals use to conserve energy under extreme hot and dry conditions . The metabolism slows, the heart rate slows, breathing slows and the animal usually seeks a cool place during estivation.
How is estivation an advantage?
Estivation saves energy
Estivation allows mammals to save energy when food availability during drought in arid regions is low. When in estivation, the MR can be greatly reduced, resulting in substantial energy saving.
What do animals do when they estivate?
Estivation is when animals are dormant because weather conditions are very hot and dry. Their breathing rate, heart rate and metabolic rate decrease to conserve energy under these harsh conditions. These animals will find a spot to stay cool and shaded .
What does estivation mean in biology?
Definition of estivation
1 zoology : the state or condition of torpidity or dormancy induced by the heat and dryness of summer : the state of one that is estivating Some animals, including various species of snakes, land snails, and lizards, enter a state of dormancy, or estivation, in the summer when water is scarce.—
How is estivation different from hibernation?
Hibernation or “winter sleep” is the state of inactivity or low metabolic process performed by the animals during winters. Aestivation or “summer sleep”, on the other hand, is the low metabolic process by the animals during summers .

Definition of estivate
intransitive verb. 1 zoology : to pass the summer in a state of torpor or dormancy Snails combat desiccation by estivating, that is, burrowing into the mud and sealing up the shell with mucus until conditions improve.— Mark Woolhouse — compare hibernate.
What type of adaptation is estivation?
11.1.
Aestivation is generally defined as a type of dormancy , which is a survival strategy used to sustain lack of food and other extreme conditions (Pinder et al., 1992; Abe, 1995; Storey, 2002). Animals that aestivate become inactive and stop feeding in response to warm temperatures.

Can humans estivate?
Similarly to the way human hibernate during the winter, estivate can refer to the action of spending the summer in one place, eschewing any travel . At the same time, I find myself sympathetic; we are all dreading the heat that we can feel gathering itself, about to crash down in a week or so.
Is estivation a learned behavior?

Is estivation innate or learned?
Desert animals appear to estivate in response to lack of food or periods of drought. On the other hand, Australian long-necked turtles will estivate even when they are kept in a laboratory with constant food and water. That means that estivation is an innate behavior that depends on internal and external cues.
Why do frogs estivate?
Frogs estivate to survive hot summer temperatures or periods of drought . Hibernation, on the other hand, is a frog’s means of surviving freezing winter temperatures.
What kind of animals do estivation hibernation?

Behavioral adaptation: something an animal does usually in response to some type of external stimulus in order to survive . Hibernating during winter is an example of a behavioral adaptation.
What would happen if humans hibernated?

So, hibernation in humans can cause brain damage, memory loss, weaker immune system and indigestion .
Can humans hibernate without aging?
Even though humans don’t typically go into torpor of their own volition—and our bodies typically prevent it by shivering—Drew explains that there’s no single “hibernation molecule” or organ that humans lack . In fact, torpor can be induced by doctors in extreme circumstances.
Can humans hibernate like bears?
The fact that large mammals such as bears and even primates, such as the fat-tailed dwarf lemur of Madagascar, can hibernate means that theoretically humans aren’t too big or energy-hungry to enter torpor.

The down side is that they don’t give much flexibility, so if things change, you’re stuck with a behavior that doesn’t work very well.
What is estivation in an amphibian?
ESTIVATION. When amphibians estivate, their breathing, heart rate, and metabolic processes such as digestion all dramatically slow down . This decreases the organism’s need for water. Some frogs and salamanders form a mucus cocoon around themselves to prevent water loss through their skin.
