With the onset of cold weather, some people begin to think how to transfer the winter four-legged inhabitants of the earth.If some of the animals we know that they have started a deep sleep, what to do other animals, which we almost did not hear anything?For example, rodents that do when winter comes?Or if a mole falls into hibernation?Also, these Norns can be related and other issues that should be discussed.Let's start from the beginning.
Types spyachek
Before proceeding to the consideration of the topic, it is worth noting that there is not only a winter kind of sleep called hibernation, but the old, known to some as "estivation."There are also types of spyachek, which are distinguished by their duration.It is seasonal, daily and irregular.The last option can happen to beast at the moment of unexpected bad weather.In addition, there are states that are very similar to hibernation.They are called stupor, psevdospyachkoy and simply prolonged sleep.It may be asked: who do not hibernate, but is simply in a daze?Of such things are common lizards, frogs, snakes, salamanders and newts.Although outwardly all states may be similar to hibernation, though they are different processes that take place inside the body.
What hibernation
Every living organism needs a certain amount of sleep to enjoy a full life.But some animals, unlike humans, are able to sleep without waking up for many days and even months.What is hibernation?This is a condition in which the body does not require the consumption of food.This is possible due to the delayed operation of physiological processes, such as respiration and heartbeat as well as the reduction in body temperature.During deep sleep the animal becomes almost cool because of the strong slowdown of the development process.Therefore it is natural to wonder whether the mole falls into hibernation, because otherwise it survive?
What is needed sleep
With the arrival of winter, even on clear days are very cold and frosty night.Many animals becomes hard to earn their living.
Most birds escape from hunger, leaving their homes, other animals bravely survive, someone has to die, and the rest goes into hibernation.For what?To keep warm, the body needs sufficient energy, which can be obtained from food.But in the winter to get food is not so easy, and energy to find her out a lot, and found the food can not make up for the cost of the animal.So, as in the period of frost is limited to the amount of food, the natural question arises: Does the mole falls into hibernation in the winter, and what other animals are not averse to lie down in the cold?
Who sleeps, and who is awake?
few animals escape from the cold winter hibernation.Such animals include dormice, hamsters, bears, raccoons, badgers, squirrels and chipmunks.The number of those who would like to lie down, also includes hedgehogs, all rodents, some species of opossums, cheirogaleidae and some other animals from warmer countries.The cold also did not meet the bats as they sleep soundly in this period.By the way, the bear falls into a shallow sleep stage and can be wake up, but the animal is very dangerous as wakes instantly.Bear attacks the one who disturbed him.
But there are those who do not hibernate, as adapted to survival during the cold weather.Such animals are hares and hoofed animals that produce food, gnawing bark from trees.Also continue to watch the predators, such as wolves, foxes, lynx and others.But many will be interested to know that moles do not hibernate in the winter, they continue their livelihoods.
process of hibernation The hibernation
animal may fall at the zero mark on the thermometer, and the body temperature of the animal acquires a mink.Small animals are usually found in the present, a deep hibernation.Sometimes heartbeat occurs at a frequency of all strokes per minute.After retiring to sleep, like a dying animal, it can take the hands poterebit, and he did not respond.But every few weeks or days the animal briefly waking up to drink water and go to the toilet, and some even backed up by food.After satisfaction of the needs of the animal goes back to sleep.Sometimes this requires a day.By the spring of animals lose almost half of their body weight, so in the summer zhivotnyoe tend to gain a new layer of fat.Interestingly, the bears are not so manifest the effects of hibernation.Although this beast wakes up very hungry and for the entire warm period he eats every day for the future.Bear in the summer gathering of about 10-15 centimeters of body fat.
Understanding moles
But let's talk a bit more about the underground creatures.So, if the mole falls into hibernation in the winter?As we have seen, this animal is active all year round, despite the arrival of winter.The animal lives in its territory and is building underground tunnels, which moves freely.To do this, he has a sensitive snout, which has a proboscis.But for fast moving and tilting the soil at a mole has developed two front paws.The structure of these limbs surprises - for the convenience of his hands "look" outside.Hindlegs almost not adapted to the movement, but that the animal does not suffer.To understand whether the mole falls into a deep sleep or remain awake throughout the winter, you need to figure out what kind of lifestyle he leads.
Life mole
This animal is best adapted to life underground.The interesting thing is that this animal pulls out a new move with great speed.From time to time it throws over the surface of the earth, and it is to these mounds can be determined that the animal had crawled under the ground.European Mole, or ordinary (the name of the same animal), lining his lair soft materials.Usually he lives under the earthen slides (molehills), under which there is a ring-depth course, narrowed upwards.The den itself may lead one or two ways, which runs about a dozen branches.This animal has its own "city" to dwell at any time of the year.
Many, knowing that the animal is able to dig tunnels deep enough, could not understand why the mole falls into hibernation.But in fact it was only a suggestion.While some continue to argue that if the animal does not run into hibernation, in the most severe frosts it still slows down vital functions and flows into the "nap".In this regard, the question arises: how many days spent in hibernation mole?It should be noted a peculiarity of this animal, which will help to understand the issue.
Power mole
main diet of these animals up earthworms, larvae and insects.Surprisingly, the food is creeping into the tunnel mole on a large scale on their own.Worms tend to these burrows, because here is warmer than in the rest of the ground, and here their fragrance attracts animal.Let us remember why other animals hibernate.In winter, it is difficult to find food.But if you take the mole, his food remains with him under the ground, so it becomes clear whether the mole falls into hibernation during the cold or not.That is, he does not need to be in hibernation, as he provided food and warm enough space, which is enough for the whole winter.
also interesting that this small animal for food at one time required to eat 20 grams of worms.After he is satisfied, the mole goes to sleep for four hours, after which he wakes up very hungry and needs re-energize your body.In just a day this mammal uses about 60 grams of food, which are divided into several stages.This animal is not able to go without food more than 12-17 hours.That is why the animal does not cease to be active, even during the winter period.
