Earth, an ordinary one among many -type earth planets, , but at the same time, it has many "extraordinary" characteristics. In addition to the differences in geographical environment and climate ecology, the most obvious thing is the characteristic of "existence or not". According to statistics, 71% of the earth is ocean, and 20% of the land area is desert. Obviously, these two types are not suitable for human habitation. But "never ends" is the precious thing about the earth. Without humans, there are many other creatures!
There is one area between my country and Mongolia, with a total area of 1.3 million square kilometers. At the same time, it is also the fifth largest desert in the world. Now, it has good news again! According to the latest news announced by the Sen Huan and Sen Protection Institute of the Chinese Academy of Forestry, recently, in the "national bear" Gobi Bear protection technical assistance project of Mongolian , Chinese experts used the unique DNA technology to carry out research on the recovery of Gobi Bear population: from 23 ten years ago to 52!
Gobi bear is a very strange species that has created many uniqueness, but many people have never heard of it. So what is special and how precious is it? Let’s learn more about its story below.
is more precious than pandas, and the "only" source of desert bears is also full of mystery
As we all know, pandas have always been a rare species in our country. It is just that with the significant results of ecological protection, it has just been "downgraded" shortly after it was "reduced". However, as a "national treasure" species in my country, its status is still unshakable. However, in neighboring countries, there is also a kind of "national bear", which is the Gobi bear. In terms of quantity and difficulty of protection, it can be said that its current situation is even more precious than that of our country's pandas.
Gobi Bear, an animal affiliated to the brown bear subspecies. According to the official encyclopedia, it is currently the only desert bear in the world, and southwestern Mongolia is its only "base" in the world. But it is worth noting that although it is so rare and special, its source is full of mystery.
It is reported that in order to protect natural resources and actively save endangered wild animals, Mongolia has established as many as 49 nature reserves by the end of 1999. For Gobi Bears, only the 141,400 square kilometers of Altai Province in the southwest is their only home. Then the question comes. If they are always here, they will not appear out of thin air. So where did they come from?
According to Nature, the Gobi bear is suspected to be a relic of the Himalayan brown bear, a separate subspecies that began to branch and evolve independently 500,000 years ago. At the same time, relevant genetic studies have shown that Gobi brown bears are most likely the offspring closest to the original brown bears. However, in terms of the current situation of brown bears, because the number is too scarce and the support of human protection is greater, so in terms of the protection of the new Gobi bear DNA, China is one of the main sources of promotion, and it can be said that it has made great contributions!
and sheep can get along with brothers and can also seize food from the mouth of wolves. Why are Gobi bears still so rare and endangered?
Gobi bear, when you suddenly hear it, many people may think that this is a very ferocious species, just like the brown bear and black bear in our country, you can challenge wild boars and tigers. But in fact, the Gobi Bear, which exists alone in Mongolia, is not as powerful as imagined. First of all, in terms of body size, the adult male individuals of Gobi bears are only about 190-280 kilograms, which is smaller than most other brown bear subspecies. And very special is that it does not prey on other large mammals, but instead feeds mainly on plants and plant fruits.
But if you don’t eat it, it does not mean you can’t eat it. I still remember that when Mongolia encouraged herding at the beginning, many herders were very happy, but because they were worried that the Gobi bears would eat sheep, they hunted them on a lot. So this also forms a law that will make you feel that Gobi bears can actually eat sheep, especially when you are hungry.Therefore, when the Rubik's Cube heard the story of "The old herder Bagen has been shepherded for three years and always with the bears." Why didn't the bear eat all the sheep when he met herding sheep?
According to the news published in the Mongolian Newspaper, a big brown guy accidentally broke into a desert pasture in the Gobi Altai Province, Gobi, Mongolia. The old man Bagen, the owner of the flock, suddenly discovered it when he drove the sheep out of the sheep pen in the morning. It looked stronger than the sheep, and it was secretly entering the flock and could not be kept in order to eat the sheep. In order to protect the flock, the old man Bagen began to drive away the Gobi bear by drawing ropes and firing a gun. But unexpectedly, the bears returned uninvited for several days, and the flock of sheep was not missing even a small lamb .
helpless, and finally the old man Bagen asked the experts for advice. According to experts' identification, it turned out to be the legendary Gobi Bear. It looks very similar to a grizzly bear, but it is the only bear that can adapt to the arid environment of the Gobi Desert, not eat sheep, and even become brothers with sheep. At the end of the story, it is reported that Bagen actually herded the sheep and the Gobi Bear for three years and five months until the Gobi Bear no longer appears one day.
Gobi bears often appear in flocks, but there are actually different opinions from all walks of life. The herders believed that the Gobi bear might have been lost and got used to staying in the flock of sheep, so they didn't eat sheep. Netizens believe that it may be that this Gobi bear might want to find something to eat in the sheep pen, but they are vegetarian and do not eat sheep. The experts also coincide with the netizens' ideas. Water in the desert environment is very precious, and food and grass are even less common in some seasons. Gobi bears go to the sheep pen to find food in order to survive. This is also a normal behavior.
Then the question arises, why are the Gobi Bears actually quite brave, but are so rare now, even on the verge of extinction? In fact, the Rubik's Cube has also summarized it, which is nothing more than the following reasons!
First point, poaching is serious. In order to obtain bear bile, the Gobi bears in Mongolia were living in a fixed area and were all alone, so some hunters extended their claws to them.
Second, the environment is getting worse and worse. Although Gobi Bears can dig holes to store water, dig holes to store food and spend the winter, they will wisely wipe away footprints with branches and seal the holes with stones, they cannot withstand the global climate becoming increasingly harsh, and they cannot withstand the invasion of human activities in their living space. High temperatures, lack of water and food have become their "death talisman".
Last, and most critical point, that is, although the degree of protection has been strengthened now, the number of this species is too small, resulting in limited population genes. At the same time, Gobi bears only gave birth once every two years, and only one at a time. In addition, the survival rate of cubs was extremely low, and in this way, the number of Gobi bears eventually decreased, and at one point was as small as 22.
Mongolia is close to my country, why doesn’t it take the initiative to introduce Gobi Bear?
Many netizens said that since our country is participating in technical rescue of Gobi Bears, and Xinjiang in our country happens to be close to southwestern Mongolia, why not take the initiative to introduce Gobi Bears? In fact, it’s not that I don’t want to, but that there is no better way at the moment.
As for Xinjiang, my country, there is a similar environment in the existing living area of Gobi Bear and so close to it. It is indeed a rare place for Gobi Bear to survive. The reason why it was not introduced on the fly is that the Gobi bear species are now extremely fragile and they are reproductive isolation from other brown bears. Artificial migration may cause more serious extinction harm.
Secondly, no matter for the ecological balance of our country or Mongolia, it should not be introduced rashly. Just like many foreign invading creatures, aren’t “Devil’s Flower” Canadian Yizhihua, crocodile gar , fushou snail , etc. the best? What do you think?
