关键区别 - 滞育与Hibernation
Hibernation is an adaptation that mammals possess in winter that makes them inactive and metabolically depressed. Diapause is another adaption that creates a temporary pause in the processes of growth and development of animals。Diapause takes place in adverse conditions during both winter and summer while hibernation takes place only during winter。这是关键区别在冬眠和隔离之间。
What is Diapause?
吐腹定义为一种动物进行保护以保护自己免受不利环境条件的状态。在此阶段，动物在生长和发展过程中暂时停顿。滞育发生在昆虫，螨虫和甲壳类动物等动物群体中。它还包括卵子species of fish in the order Cyprinodontiformes. The main intention of diapause is to protect from adverse environmental conditions such as extreme temperature conditions like winter, droughts and low food availability.
它发生在夏季和冬季。滞育可能发生在生活的任何阶段。但是发现，滞育最突出的阶段发生在不动的阶段p。The level of diapause changes with species. Diapause could also occur at active stages of life that undergo extensive migration (example: adult monarch butterfly). Diapause is initiated with a decrement of bodily concentrations of growth and molting hormones.
These fluctuations coincide with physical changes such as a change in temperature, day length and the availability of food. Unlike hibernation, diapause is a temporary effect for a short period of time. Diapause could be determined genetically. But a slight deviation occurs to this theory if the animal is raised under environmental conditions that are constant and favourable.
Hibernation is defined as a state where the metabolic activity of animals reduce to a greater extent and lowers the body temperature that creates metabolically depressed conditions in them as an adaptation to withstand adverse environmental conditions during winter. This term, hibernation could be applied commonly to all types of dormant conditions develop by vertebrate animals. Therefore, hibernators include different types of fish, amphibians, reptiles and mammals like bears. These mammals use dens as hibernating habitats during winter.
爬行动物和哺乳动物不会大大降低其体温，也不被认为是真正的冬眠者。真正的冬眠者在冬季的大部分时间里都在一个接近死亡的州度过。除非进行仔细观察，否则该动物可能会死亡。他们的体温接近00C. The rate of respiration becomes low where it becomes almost very few breaths per minute. The heart rate becomes barely perceptible with slow and gradual beats. The animal slowly awakes only when it is exposed a considerable amount of heat. Once it receives the needed warmth, it requires additional 1-2 hours to reach the alert state.
What are the Similarities Between Diapause and Hibernation?
- Both Diapause and Hibernation occur in different species mammals and insects.
- Both Diapause and Hibernation result in adapting the animal to withstand extreme environmental conditions.
- Both Diapause and Hibernation prevent the death of animals due to adverse effects on the environment.
|Diapause is defined as a state in which creates a temporary pause in the processes of growth and development of animals as an adaptation to withstand adverse environmental conditions.
|Hibernation occurs only during Winter.
|Amount of free water is reduced during diapauses.
|No such adaptations occur in hibernation.
|Temperature is not lowered up to greater extents during diapauses.
|Mammals like bears, California pocket mouse, kangaroo mouse, bats, different insects and different species of birds and reptiles show hibernation.
动物王国具有不同的适应性来承受极端的环境条件。隔离和冬眠是保护动物免受环境不利影响的这种状态。处置被定义为动物受到保护免受不利环境条件的状态，在这种状态下，它们在生长和发展过程中暂时停顿。这是一个暂时的效果。它发生在冬季和夏季。冬眠定义为一种状态，在这种状态下，可以在更大程度上降低动物的代谢活性并降低体温，从而导致代谢抑郁症状，以适应冬季在冬季承受不利的环境条件。真正的冬眠仅将其体温降低到00C. This is the difference between diapauses and hibernation.
