Will the Northeast Tiger suffer when the snowstorm strikes? What happened? Affected by the cold wave, there have been heavy blizzards or heavy blizzards in Inner Mongolia and parts of Northeast China recently. The thickness of snow in some areas is as high as 45 cm. Will the Northeast Tiger suffer when the snowstorm strikes?

Will the Northeast Tiger suffer when the snowstorm strikes? What happened? 1 Affected by the cold wave, there was an obvious cooling process in many parts of the country. In many places, the temperature plummeted by 20℃, and snowfall and even blizzard appeared in many places.

According to the forecast of the Central Meteorological Observatory, there will be heavy snowstorms in southeastern Inner Mongolia, central and northern Liaoning, western Jilin, central and southwestern Heilongjiang and other places today and tomorrow. Among them, there is a heavy blizzard in southwestern Heilongjiang, and the newly added snow thickness is 8- 15 cm, and the newly added snow thickness in some areas can reach more than 30 cm.

Blizzard has a great influence not only on human beings, but also on local animals. Among them, "Wandashan No.1", which entered the village by mistake in the first half of this year, is even more touching. Many people are worried about such cold weather. Wandashan-1 Will you be hungry and cold in the wild?

Frost resistance of Siberian tiger

In fact, there is absolutely no need for us to worry about whether the Siberian tiger will freeze to death, because the freezing resistance of the Siberian tiger can withstand natural screening, and even in the environment of MINUS 30 degrees, they can still maintain vigorous vitality.

The reason why Siberian tigers are so outstanding in frost resistance is inseparable from their hair and subcutaneous fat.

Compared with other tigers, especially Bengal tigers, Siberian tigers have longer and thicker hair and more fluff. Thick hair can help them resist the cold.

Secondly, before entering winter, Siberian tigers will eat a lot and store more fat. At this time, they will gain weight and look like a "plump fat man". After winter, the weight of Siberian tiger will gradually return to normal level.

Thick subcutaneous fat can help them resist the cold, even if they spend the night on a cold winter night.

In the wild, Siberian tigers hide in warm caves and Woods to keep out the cold after foraging, especially young and old Siberian tigers.

With multiple guarantees, the Northeast Tiger can adapt to the cold winter climate in Northeast China. Therefore, although the temperature drop is large and the local temperature is low, as long as a large amount of fat is stored in autumn, Wandashan No.1 will basically not be frozen this winter.

In fact, the real factor affecting the Siberian tiger in winter is not the low temperature, but the thick snow. Effect of Snow on Siberian Tiger

If it is simply cold, the Siberian tiger is not afraid, but the local snow is deep.

We know that snow can cover all vegetation on the earth's surface. If the snow is shallow, herbivores can arch the snow to find grass roots below the surface, or feed on hay, and the survival rate will still be higher.

However, if the snow is deep, some herbivores with weak ability to arch snow will find it difficult to feed, and they need the help of other animals at this time. For example, in 2020, some herders observed roe deer foraging behind their horses. This is because the snow in the place where the horse stepped was dug up, and the grass on the ground was exposed. The roe deer had weak ability to arch the snow and needed to rely on these grass for a living.

In addition, silly roe deer also likes wild boar, because wild boar's tusks are very long, and wild boar will arch away the snow in winter, which can help silly roe deer eat.

Although some animals can dig deep snow, if the local snow is deep and the temperature is very cold, a large number of herbivores will still die because it is difficult to feed.

A large number of herbivores die, which will reduce the food source of wild Siberian tigers. At this time, it will be more difficult for them to find food, and even they will die because there are too few prey.

In addition, the thick snow will also affect the hunting of tigers. Walking in thick snow is easy to make noise, and wild animals are alert by nature. Once they hear the noise, they will run away, making it harder for tigers to hunt.

Also, there may be hidden dangers under the thick snow. Deep pits or underground rivers on the ground may be covered with snow. The Siberian tiger is relatively heavy. If you accidentally step into a deep pit, you are in danger of being injured.

Of course, the northeast is the northeast after all, so it is impossible not to snow in winter, and the local wild animals are also used to snow in winter. As long as the local snow is not too deep, or the deep snow will not last for a long time, it will not have a particularly great impact on local wildlife.

If there is really deep snow, humans will also intervene. For example, there was a heavy snow in Suiyang forest area last winter, which made it much more difficult for ungulates to feed. In order to supplement the nutrition of ungulates, patrol personnel will regularly carry out "supplementary feeding" work. Put salt brick, straw, corn, radish, cabbage and other wintering foods in ten forest spots such as Wenquan River, Sancha River and Yuanshan within the scope of Tiger and Leopard Park, monitor local ungulates and traces of activities, and master the trajectory and laws of local animal population activities.

Ungulates are the food of Siberian tigers. Protecting ungulates is also indirectly protecting Siberian tigers. For example, the staff found that there would be traces of wild Siberian tigers near the feeding point, obviously from the prey of followers.

In addition to feeding ungulates, the staff will also feed the Siberian tiger in order to eliminate the adverse effects of heavy snow on local animals and help them spend the winter safely.

This year is the first winter when Wandashan-1 lives independently from its mother. Although it is very cold this winter, I believe Wandashan-1 can survive the winter successfully with a series of protective measures.

Will the Northeast Tiger suffer when the snowstorm strikes? What situation 2 is affected by the cold wave? Recently, there are heavy snowstorms or extraordinarily heavy blizzards in Inner Mongolia and parts of Northeast China. The thickness of snow in some areas is as high as 45 cm, and the deepest snow in Tongliao, Inner Mongolia is 68 cm.

Meteorologists pointed out that the heavy rain and snow weather brought by the cold wave to Northeast China is rare in the same period of history and lasts for a long time. 1 1 The accumulated precipitation at some stations may exceed the historical extreme value in the same period, which is extreme.

You know, this blizzard can only be used as a prelude to this winter. According to the National Climate Center, it is estimated that 1- next February, there is a great possibility of staged extreme cold wave events in China.

Affected by heavy snowfall, parts of Northeast China were affected. Among them, in Tongliao, Inner Mongolia, a large number of agricultural greenhouses were crushed, and the tops of livestock sheds were crushed, and some rural livestock were frozen to death.

We should know that livestock in rural areas still live under the protection of human beings, while wild animals are overwhelming. So how should wild animals spend the winter in this extreme snowstorm?

hibernation

Different creatures adopt different strategies in winter, and a small number of them hibernate for the winter. For example: snakes, black bears, beavers, etc.

Snakes choose to hibernate because they are cold-blooded animals. When the outside temperature is low, their body temperature will also drop, which will make it difficult for biological enzymes to catalyze energy, thus making their bodies hard and unable to move. If snakes can't find a safe and warm place to spend the winter before it gets cold, when the outside temperature is low, they will lose the ability to move directly, let other animals kill them, and even their food mice will devour them.

There used to be a zoo in Nanjing, where staff fed mice to snakes. They were not eaten by snakes, but as spicy strips.

Black bears are warm-blooded creatures, and there is no other reason to choose hibernation. It is difficult for bears to find food simply because of the sharp drop in food in winter. In order to save energy, the black bear has to lie still in the cave until the temperature rises next year.

It is worth noting that black bears still have the ability to move when they hibernate. If they are annoyed, they don't mind "serving a meat". However, there is an animal that is the natural enemy of the black bear. It's a Siberian tiger. If the Siberian tiger finds the wintering ground of the black bear, it may eat the black bear as food.

A heartbreaking scene happened in Xiaoxing 'anling. A bear is favored by scientists because it is very smart and will cooperate with the staff to check. But scientists found that this cute little bear was hunted by the Northeast Tiger and ate most of its body.

Generally speaking, hibernating animals, whether warm-blooded or warm-blooded, mostly store more fat in autumn. Thick fat can not only be used to consume energy, but also keep warm in cold winter. Some small animals will store a lot of food in autumn to spend the long winter.

Of course, if winter is very cold, hibernating animals don't store enough food and their body fat is not thick enough, they may freeze to death or go out for food at their own risk.

How to survive the winter without hibernation?

There are many animals that don't hibernate in winter, and animals that don't hibernate face greater challenges.

In fact, in the cold winter, wild animals will try their best to resist the cold. For example, a silly roe deer will make a snow nest to keep out the cold. Because the snow cave is hard-won, the silly roe deer ran away for a long distance after encountering danger, and will come back again soon to see if the danger has gone away, which gives the hunters a chance to hunt, so the hunters of the older generation said that they don't have to chase after encountering the silly roe deer and will come back in the future.

Northeast tigers will also find a relatively warm place in the cold winter, such as caves or shelters. Their thick fluff and fat can withstand the low temperature of MINUS 30 degrees Celsius and basically will not freeze to death.

In fact, what really threatens animals in winter is not the cold, but the snow, especially the thick snow. This is because thick snow covers everything on the surface, and herbivores live on grass and grass roots on the surface in winter. Thick snow will prevent them from digging up the snow on the ground to find food, so they will starve to death.

The wild boar herd near Beijing failed to resist and froze to death in a particularly cold winter.

Some animals have weak ability to arch snow, and thick snow will make it difficult for them to eat. For example, silly roe deer can only eat the snow arched by wild boar when the snow is thick, but because the snow arched by wild boar is small, when the snow is thick, a large number of silly roe deer will still die because of lack of food.

For Siberian tigers, thick snow is not conducive to survival, because thick snow will slow down their running speed, and thick snow will make them difficult to hide, which will lead to noise when hunting and scare away prey.

In addition, when the thick snow freezes a large number of wild animals, it will also reduce the food of the Siberian tiger and even cause starvation.

Now, in order to protect wild animals, whenever it snows heavily, the staff in the reserve will supplement the feeding of wild animals, in order to prevent them from lacking food in winter and survive in the next spring.

Will the Northeast Tiger suffer when the snowstorm strikes? What happened? The snowfall lasted for 46 hours, and the snowfall broke the extreme value of 195 1 year. The thickness of snow in Kulun Banner, Tongliao City, Inner Mongolia reached 59 cm, and snowstorm warnings were issued in many places in Northeast China. The snowstorm and strong wind responded at level II, 1 person died, 176 livestock died, and excessive snow may cause white disasters. ...

Are these words too worrying?

The northeast cold wave affects the hearts of the people all over the country! Cold wave and blizzard not only affect people's production and life, but also seriously affect livestock, even a "white disaster"! White disaster is a kind of disaster, because the snow is too thick and lasts too long, which leads to the grass being buried, and the livestock can't eat normally, which leads to the weight loss and death of the livestock.

Some people are more worried. Will the Northeast Tiger freeze to death by the cold wave? Is Wandashan No.1 going to be okay in the wild?

After all, last winter, more than 20 Siberian tigers gathered under the trees of the Northeast Tiger Garden in Harbin, and the scene of holding a group to keep warm was still vivid. Looking at the momentum of this cold wave this year, the northeast will be much colder than last year!

Will this cold wave freeze the wild Siberian tiger to death?

The wild Amur tiger is mainly distributed in Heilongjiang in the northeast of China and the eastern mountainous areas of Jilin Province, such as Wandashan, Laoyeling, Changbai Mountain and Zhangguangcailing. , mainly distributed in Korea and the southeast of the Russian Far East abroad. The climate in these places is very cold in winter, and the low temperature is often below MINUS 20 degrees.

However, the temperature of this cold wave is still not low. For example, the low temperature in Harbin is only below zero 13, while the average low temperature in winter in Harbin can reach below zero 19.

Therefore, despite the heavy snowstorm, this cold wave has basically no effect on the wild Siberian tiger, and we don't have to worry that the wild Siberian tiger will freeze to death.

How low will the temperature cause the Northeast Tiger to freeze to death?

Most people don't know how low the Siberian tiger can withstand, thinking that it can't be frozen, but it can't be carried at a certain temperature!

According to the data in the Encyclopedia Britannica, the temperature range of the Siberian tiger is "-40℃ to 40℃", and the temperature difference is as high as 80 degrees, which is much stronger than human fragile tolerance!

In Northeast China, although the general minimum temperature can only be around 30 degrees below zero, there are many places where the extreme temperature is below 40 degrees below zero in winter, such as Mohe in Heilongjiang and Genhe in Inner Mongolia, where the extreme temperature can reach 50 degrees below zero. Wild tigers can't survive in the cold.

Low temperature is not the biggest difficulty. Where is the difficulty?

Although extreme low temperature can cause tigers to freeze to death, the biggest confusion for tigers is that they lack food in cold weather. The main food of Siberian tiger is deer, wild boar, musk deer and roe deer. Occasionally they prey on snakes and fish, and also eat wild fruits such as pine nuts, walnuts, hazelnuts and raspberries.

When the temperature is too low, many hibernating animals are resting, and ungulates also reduce their activities because of the deep snow. Too deep snow will cause tigers to make noise when they move, which may lead to the failure of hunting. This is the biggest difficulty that tigers need to face!

After all, there are few places that can reach below MINUS 40 degrees, and even the temperature in most parts of the Arctic is above MINUS 40 degrees.

There is no doubt that the Northeast Tiger has a strong viability and can tolerate such a strong low temperature. Although this cold wave is threatening, it is really nothing to the wild Siberian tiger! They won't have any survival crisis because of this cold wave, don't worry!
