What is the difference between estivation and hibernation

Aestivation is the type of summer sleep, performed by cold-blooded animals. Duration It is for the whole winter. It is of short duration. Process As hibernation is the sleep during the winter, the animals look out for the warmer place, their metabolic activities slow down, and it is the dormant stage. Aestivation is a summer sleep, so animals search for the moist, shady and cool place to sleep. Examples Bats, birds, mammals, insects, etc.

Bees, snails, earthworms, salamanders, frogs, earthworms, crocodiles, tortoise, etc. Importance Hibernation helps in maintaining the body temperature and thus avoids from any internal body damage due to low temperatures. Aestivation also helps in maintaining the body temperature by avoiding the excessive water loss and any internal body damaged due to high temperatures.

The phenomena where the animals go to almost dormant condition, their metabolic activity gets lowered. Hibernations is the common term used for the reptiles, amphibians, and fishes which spend their winter with the body temperatures near to the freezing. Such hibernators like mammals and bear spent maximum time in dens.

Though mammals are not the true hibernators as their body temperature does not get much lower, and they are not entirely inactive. Insects hibernate themselves by keeping themselves warm in the holes of the ground, or in rotting logs or under tree bark, whereas frogs, turtles, and fishes take shelter in the deep water of lakes and ponds, or by burrowing in muds. Hibernations is called the dormant condition as the animals emerge to be almost dead or near to it. Their body temperature is around to 0 degrees C or 32 degrees F.

The only system which is active in their body is breathing, which is also at a slower rate, like their heartbeat. Another main significant problem faced by these animals is the unavailability of food. Hence, before winter sleep the animals eat extra food and store in the form of excess fat, which is supplied in the form of energy while sleeping. Cold temperatures cause reptiles and amphibians to hide underground, in rock crevices and in burrows to stay warm and safe.

Their activity, body temperature, heart rate and respiratory rate drops like in hibernation. Cold-blooded animals will move on warmer winter days and find water, unlike hibernators who are in a deep sleep and do not move at all. 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. Many reptiles and amphibians estivate and some mollusks, insects, fish and mammals will estivate as well.

Whether it is hibernation, brumation, estivation or a combination of these processes, animals have an amazing ability to adapt and survive in their different environments.

Blog Ask a Naturalist: Hibernation vs. January 13, Discovery Place Nature. As the weather turns cold, many animals have gone into hibernation to get through the winter. Only pregnant polar bears den. Rodents are another group of placental mammals known to aestivate. Birds : Although it is widely believed that birds migrate to avoid adverse conditions and employ torpor less frequently than mammals, several birds are known to display torpor use even in summer.

Key features of aestivation include strong metabolic rate suppression, strategies to retain body water, conservation of energy and body fuel reserves, altered nitrogen metabolism, and mechanisms to preserve and stabilize organs, cells and macromolecules over many weeks or months of dormancy.

The researchers found that during hibernation , animals were much less likely to die , so those species that hibernated were able to reach higher maximum life spans the longest observed lifetime of a member of the species , but they sacrificed how many offspring they had each year, Turbill said. Contrary to what is widely believed, black bears are not true hibernators. Mammals such as ground squirrels, woodchucks , and chipmunks are animals that enter into true states of hibernation. How to enable or disable hibernate in Windows 10 Right-click on the Start button and choose Command Prompt Admin from the pop-up menu.

In the Command Prompt window, type powercfg. To enable hibernate in Windows 10, open the Command Prompt again and type powercfg. Below a certain temperature, human hearts cannot remove excess calcium so they fail. Ruf says they have special pumps to remove calcium, which we lack. What is the difference between Estivation and hibernation? Category: science physics. The main difference between aestivation and hibernation is, aestivation is summer sleep while hibernation is winter sleep in which an organism passes the winter period in dormant condition.
