Which animals hibernation?
the warm and cold -blooded animals of hibernation, including some chipmunky species, hedgehogs, frogs, turtles and even some fish. Most animals that are hibernation in the northern and extreme southern areas of the world - the colder climate of the world. The variety is quite extensive and also includes hamsters, opsums and dachshunds. Bears, perhaps the most famous of such animals, are not as deep as many other animals, so some scientists do not consider it a real hibernation.
Many small thermal -circular animals are hibernating hibernation during the winter, including many rodents such as dormouse, ground squirrel and woodchuck. These animals are obliged to hibernate for part of the year, and as soon as this process begins, it is very difficult to awaken. For example, the body temperature of the hazel track drops just above the frost and its heart beats only a few times every minute. Several these animals wake up regularly to eat, but others remain in this deep sleep for up to six months. Among other distorted animals that hibErnace belongs, belongs to mice lemurs and mountain pygma Vačice.
Most birds are not really hibernation, although it does an ordinary poor room, a species in a family called Nightjars or Nighthawks. Found in the southwestern US and Mexico, this bird can spend weeks or months during the winter in an inactive state. Other birds can go to a state known as Topor, during which they slow down their metabolism and body temperature, but it usually takes only a short time, often overnight. In many cases, hibernation is described as a long -term tent.
bears are the most often identified animals that sleep during the winter months; However, many scientists classify the bear as a real hibernator because they do not go through the same degree of physiology that other hibernation animals do. For example, while bearish heart rate and breathing slows down, its body temperature does not drop much. Along with some bats with the bears thatKé easily awakens. Most bears release their young people during the winter, so the mother of the bear must be somewhat aware of during the birth process to properly tend to her young.
cold -blooded animals
Insects, reptiles and other species, including some fish, also hibernation. Because they cannot maintain their body temperatures as warm animals do, many cold -blooded animals seek refuge in hollow trees, caves or underground to protect themselves during the winter. Some wetland creatures - just like a fish - often bury in the mud at the bottom of the lake or pond. This not only protects creation from elements, but prevents the current from washing creation downstream and protects it to become food for other predators who neopravate.
Some experts distinguish between winter dorman periods of warm and cold -blooded animals. Rather than "hibernation", they refer to it as "Brumions" when it occurs at reptiles. The main difference is the energy source; Mammals eat before hibernation and use the stored fat,To get them into the winter, while the reptiles survived on the energy storage molecules. For practical purposes, however, both states are very similar.
How does hibernation work
hibernation allows the animal to slowly slow down its life support systems, often only one heart rhythm in a few minutes. This changed metabolism not only saves energy, but prevents the body of the animal to require additional food and water while sleeping. The temperature of the animal's body temperature also decreases and most of the heat is concentrated near and around vital organs. Some animals such as Opssum are born young, while the mother sleeps; Thnovators get into the case on the mother's lower abdomen, where they are treated during the rest of the mother's menbernation period.
In some cases, the weather may warm up unusually at the beginning of the season and bring animals out of their hibernation much earlier than usual. This can often prove to be a life -threatening animal, because foods such as grass and berries are not yet available.In this case, animals can starve and malnourished. Such a season may also be a threatening life to newborns, as their motherhood milk can dry out due to its lack of nutrition.
