Hibernation and diapause are adaptations of an animal in response to harsh environmental or climatic conditions. Diapause is commonly observed in insects.
Hibernation is similar to diapause; however, hibernation is only reflected in a lower body temperature, while diapause has no such symptoms. Read on to find out more differences between hibernation and vacation.
What is Diapause?
Diapause is a natural stop in the development of some animals, characterized by a decrease in metabolic activity. It is found in a variety of insects and bats, as well as some ants and snails, and possibly other animal species.
This pause in development appears to be a response to impending harsh environmental conditions. It can occur at any life stage, but is most common in pupae (eg, moth cocoons).
Diapause usually occurs when body growth and reproductive hormone decreases, which is often accompanied by differences in day length, temperature or diet. Diapause is due to genetics, however, can be overcome in the laboratory if animals receive a consistent environment as well as the good one. lifestyle
Diapause is commonly observed in insects during their development. Reducing metabolic activity causes organisms to stop growing spontaneously. It is a time of arrest of development in growing organisms.
It can occur at any developmental stage of the parasite but is most often seen in the pupal stage. Diapause occurs when the rate of hormonal growth in an organism’s body decreases. Thus, it is similar to hibernation but marked by a pause in the organism’s developmental stages.
What is Hibernation?
Hibernation can be simply defined as a state in which organisms reduce their metabolism in a deficiency often during the winter Hibernating animals are hamsters, chipmunks, inns, bats, hedgehogs and some other insects, amphibians and reptiles and hibernate Only according to birds North America.
There is general poverty that goes into complete hibernation. This fantastically dressed nocturnal bird is a cousin of the British Night King and spends the winter resting on rocks. When its body temperature drops below 5 °C it can reduce its oxygen supply by 90%, indicating that it is no longer alive.
It is a state of low metabolism in the body of an organism. Winter is seasonal and is characterized by lower body temperature, lower heart rate, lower metabolism and more.
It is found in some winter endotherms. During this time hibernating organisms go into a deep sleep-like state that slows down their metabolism and burns less energy.
During hibernation, the organism slows down vital functions such as its breathing and energy-burning heat. It is usually the response of a healthy body to the lack of food and low temperatures.
It can last from a few weeks to months. Groundhogs and most other pests go into hibernation. Other examples include bears, squirrels, chipmunks, etc. Animals need to eat as much as they can to survive the winter.
They eat so much that they build up extra layers of fat that cause these layers of fat to break into a hibernation state in order to survive.
Difference Between Diapause and Hibernation
| Diapause | Hibernation |
| Diapause is a dormant stage in the development of an organism | Hibernation is the reduction of metabolic activities in an organism |
| Diapause occurs during any time of the year | Hibernation usually occurs during the winter months |
| Diapause is commonly observed in insects. | Hibernation is common among higher animals. |
| Monarch butterflies exhibit diapause in winter or any other unfavourable conditions | Hibernation is seen in mammals such as bats, hedgehogs, and ground squirrels. |
