Fantastic Animals in the Tibet Plateau

On some highlands in Tibet, we found flocks of wild yaks ranging from a dozen to thirty, sometimes even more. Most wild yaks are black, but brown-yellow ones are extremely rare. These creatures roam swiftly on the rugged, gravel ground, enjoying the snow, forest, and eternal wind there.

 

In 1897, British Captain Henry Hugh Peter Deasy, who ended his nine-year military career in India, began his plan to explore the Qinghai-Tibet Plateau in China. Such a discovery is recorded in his book:

 Wild Yaks in Tibet

On some highlands in Tibet, we found flocks of wild yaks ranging from a dozen to thirty, sometimes even more. 

Most wild yaks are black, but brown-yellow ones are extremely rare. These creatures swam swiftly across the rugged, gravel ground, enjoying the snow, forest, and eternal wind.

Captain Dixi didn't know what a unique existence the wild yak with a rare coat color he accidentally discovered. Unique to today, more than 120 years later, the scientific community is still debating whether it should be an independent subspecies.

 

But this is excusable, after all, for most people, the place where it lives is an out-and-out wilderness.

 

I. Wilderness Carnival

Between the northwest of the Qinghai-Tibet Plateau, the Kunlun Mountains in the north, the Tanggula Mountains in the east, the Gangdise Mountains-Nyainqentanglha Mountains in the south and the Karakoram Mountains in the west, there is a vast "open space". This is the Qiangtang. , Also known as the Northern Tibet Plateau.

 

This is the largest landform unit on the Qinghai-Tibet Plateau, covering an area of ​​nearly 600,000 square kilometers, equivalent to six Jiangsu provinces. 

Here is also the area with the highest average elevation on the Qinghai-Tibet Plateau. 

At an average elevation of 5,000 meters, mountains, hills and plains are intertwined with distinct layers.

 

Meltwater from the glaciers on the high mountains follows the trend and forms intermittent inland rivers, with lakes dotted around the ends of the rivers.

 

The rivers and lakes of Qiangtang


The rolling mountains in the south block the warm and humid air from the Indian Ocean, making it cold and dry throughout the year. In addition, the desert and frozen soil are rough in texture and low in nutrition. 

The vegetation on the land is low and sparse, and the species is monotonous, mostly creeping Stipa and Wormwood.

 

Therefore, since ancient times, this place has been a restricted area for human beings. Even today, when the traffic is developed, only a few nomads are active in the marginal area.

However, in such a harsh environment, there are a large number of Tibetan antelopes, Tibetan wild donkeys, Tibetan antelopes, white-lipped deer, argali, wolves, bears, Tibetan foxes, wild yaks and other wild animals. Carnival of life.

  

The wild yak is undoubtedly the most powerful creature in this life carnival. According to the latest survey statistics, the number of wild yaks in Qiangtang is currently between 11,000 and 21,000, which is six times as much as the neighboring Hoh Xil Nature Reserve.

 

Tall and strong, they have strong cold-tolerance, drought-tolerance and load-bearing capacity. 

Yak and yak milk are high-quality sources of protein and calories, and thick fur is the best material to withstand the cold. By domesticating wild yaks, humans on the plateau have found a reliable support for life.

  

At the end of the 20th century, as the census of Tibetan cultural relics began, researchers successively discovered thousands of rock paintings on the Qinghai-Tibet Plateau, the earliest dating back to 3000 years. 

Most of the rock paintings are located in the south of Qiangtang. 90% of the images in the paintings are animals. 

Among these 90%, the yak is the most numerous and often appears as the protagonist.

And among the well-known wild yaks, there is another group of rare individuals. They are burly and golden all over. This is the unique population mentioned at the beginning of the article, and they are called "golden wild yaks."

 

II ."Sacred Cow" on the Plateau

In Tibet, all mountains have gods. There is a sacred mountain among the local population in Ritu County in the Qiangtang National Nature Reserve: Zhaqianxue Mountain, which is one of the core areas for the activities of the golden silk wild yak.

 

There has always been a legend among the local Tibetans: Buye Snow Mountain in the east of Zhaqian Snow Mountain was his wife. When Buye Snow Mountain got married here, Buye’s brother (saying his parents) gave 7 wild yaks with golden silk. Give her as a dowry, this is the origin of the golden silk wild yak.

 

Following the enlightenment of mythology, the local people regarded these wild yaks that came with the sacred mountain as gods, and believed that hunting them would lead to bad luck. 

Even the bones of the wild yak that died naturally were forbidden to be taken home.

 

They have been living in legends and stories until 2014, when researchers from the Chinese Academy of Forestry and Central University for Nationalities analyzed the genes of the golden wild yak and the black wild yak. 

They found that the genetic difference between the two is greater than the genetic difference between individuals in the black wild yak. The rarity and uniqueness of this creature has finally been scientifically demonstrated.

 

But for this unique and rare species, we still know too little, and there is no image data for reference. 

In 2016, in order to obtain more research materials, documentary director Kabu organized a film crew of about 30 people to go deep into the hinterland of Qiangtang to carry out long-term tracking and shooting of the wild yak. 

Counting from the first time he saw this unique creature, this action has been brewing for 11 years.

 

According to Kabu's years of field tracking, observation and research experience in Qiangtang, the range of activities of the golden wild yak is roughly in an area with Alu Co, Luma Jiangdong Co and Zhaqianxue Mountain as the core.

 

Golden silk wild yak's approximate range of activity

 

Although the scope of activities is delineated, their uncertain whereabouts and the maze-like terrain of the Qiangtang still make the shooting work difficult. 

The search process was also arduous, and accidents such as car traps and punctures occurred frequently.

  

Finally, they first met a group of wild yaks in a valley. From a distance, their huge bodies are very flexible, walking briskly on the mountain valleys.

 

Female and juvenile wild yaks are usually separated from males. They form groups of about dozens of heads. They can even move freely on slopes of about 30° and easily climb over snow-covered mountains.

  

However, it is not easy to search for the wild yak, which is uncertain and sensitive. With the expansion of the search area and the huge consumption of materials along with the team, the film crew had to withdraw from Qiangtang with regret, and waited 4 months before returning again. Enter no man's land.

 

This time, they encountered an adult male golden wild yak acting alone. In Qiangtang, almost no animals are its opponents. 

When it is grumpy and chooses to fight the "invaders" head-on, even the hungry wolves and strong brown bears are not taken seriously.

  

Adult male wild yak can exceed 170 cm in height at the shoulder and weigh more than 1,000 kg. 

Every part of their body seems to be born for the wilderness of Qiangtang: thick fur, strong lung capacity, sturdy limbs, and a pair of big horns.

 

Even every blood cell in the body is customized for the oxygen-dilute plateau: the cell volume is smaller, and the amount of blood per unit volume is larger, so the oxygen carrying capacity is several times that of the average domestic yak.

 

When such a giant beast rushes towards you with sand and rocks, the only option is to escape.

 

The male golden wild yak is very aggressive

 

In order to avoid interference with wild animals to the greatest extent, and to capture the survival of the wild yak in the natural state, the film crew changed the direct tracking and shooting plan to shooting with a trigger infrared camera.

 

In the lens of these infrared cameras, the golden wild yak has removed the halo of the "sacred cow", and we see the other side of them: quiet and peaceful, even a little cute.

 

They will feed on low grass and moss with their tongues full of horny barbs to provide nutrients to their huge bodies. 

When food is insufficient, they have to travel long distances to find high-quality and sufficient forage, and even need to eat snow to replenish water during the journey.

 

In order to improve the cold resistance and reduce heat dissipation on the body surface, they have evolved thick fur, and their tongues have become their radiator.

  

The perfect physiological structure and tough living habits have created them, making them a veritable "Qiangtang Totem".

 

 

III. The Tomorrow of "Shen Niu"

At the end of the 20th century, at the invitation of the Chinese government, George Schaller, an American biologist, went to Qiangtang three times to investigate wild animals. 

Through his records, we may find that the proportion of golden-threaded wild yak in the entire wild yak community decreased gradually, reaching the most. Only less than 10 heads were found at one time.

 

And through the lens of today's camera crew, we also see the difficult living conditions of this creature. Based on his own observations over the years, Kabu estimates that the number of Qiangtang Golden Silk Wild Yaks is probably less than 100.

 

Poaching, overgrazing, stealing minerals, and even walking through uninhabited areas without permission are quietly encroaching on the last habitat of this wild animal. 

Environmental fluctuations also affect the fragile ecosystem of Qiangtang. But we can also see hope.

 

In order to protect a large number of wild animals including wild yaks, the country established the Qiangtang Nature Reserve in 1993 and upgraded it to a national nature reserve in 2000. 

After the establishment of the reserve, the government set up a patrol team, trained a large number of wild guards, and patrolled the vast area to prevent behaviors that damage wild animals and their habitats.

  

After the introduction of the policy to protect the habitat of the golden silk wild yak, a local herdsman moved his 5,000 acres of pasture, reducing the number of sheep from 800 to 300. He just said calmly about this:

If the number of wild yaks increases in the future and these pastures are not enough, we will make more space for them as habitats. 

The herders will agree to these practices, and no one will disagree.

 

The wild animals on the plateau, represented by the golden-threaded wild yak, seem to be far away from us, but they are closely related to people’s lives: they are part of Tibetan culture, and they are a diverse pool of genes, viruses and bacteria that carry anthrax to humans. 

The research on zoonotic diseases such as tetanus and tuberculosis is of far-reaching significance.

 

The Beautiful Life of the Qinghai-Tibet Plateau

What's more, nature and life alone are sufficient reasons for us to act. Just as George Schaller recorded in the book "The Beautiful Life of the Qinghai-Tibet Plateau":

 

In thousands of years of history, humans have become an integral part of Qiangtang. Our ancestors have left us with numerous wild animals and rich pastures.

When I look at this grassland, what I see is Those sights that have disappeared.

 


P.S. The best way to protect wild animals is to minimize the impact of human beings. We never encourage the curious behavior of crossing no-man’s land privately. 

While disturbing the animals, it is difficult to guarantee their own safety. Let us only admire the magnificence of life in the image, and leave this land to share with the creatures.

I dyed my white hair black, but I didn’t expect to be allergic to hair dye. What's the matter?

If you love beauty, you can't be willful. Dyeing your hair can really kill you. The most common problem with hair dye allergy is allergic dermatitis. At present, research suggests that hair dye allergy may be related to allergens, individual immunity and genetic susceptibility. Although most are only delayed mild reactions, sometimes hair dye allergy can have serious consequences.


If you love beauty, you can't be willful. Dyeing your hair can really kill you

Some time ago, a news that dyed hair to death once again put the matter of hair dyeing in front of the public. Most people have become accustomed to dyeing their hair. 

After all, most people now try to dye their hair or bake oil at some time in their lives. 

However, not everyone is suitable for dyeing hair. The argument that dyed hair causes cancer is still being debated, but there is no doubt that dyeing hair causes allergies. 

Allergies are also very common. 


Allergic rhinitis, allergic dermatitis and other diseases, even if not everyone can get it, you will always have it a few people with allergies, then, what is allergic to hair dye?

The most common problem with hair dye allergy is allergic dermatitis. 

At present, research suggests that hair dye allergy may be related to allergens, individual immunity and genetic susceptibility.

 There are many studies on the N-acetyltransferase 1 gene (NAT-1) at home and abroad. This is because the most common allergen for hair dye allergy is p-phenylenediamine (PPD), and a small amount will penetrate into the epidermis and dermis. 

Participate in acetylation metabolism and transform into N-monoethylphthalate p-phenylenediamine (MAPPD) and N-diethylphthalate p-phenylenediamine (DAPPD).

Hair Dye Allergy


PPD is no longer sensitizing to the body after transformation, and will no longer cause an immune response, which proves that N-acetyltransferase 1 plays a detoxification effect. 

Therefore, the probability of detoxification genes in people with hair allergy is lower than normal people.

 

What is the relation of hair dye and angiotensin converting enzyme (ACE) gene?

In addition, the angiotensin converting enzyme (ACE) gene is also related to this. 

This is a zinc metalloenzyme whose main function is to promote the conversion of angiotensin 1 to angiotensin 2, and it can also regulate inflammation and reduce the production of inflammatory substances. 

Its specific genotype will make the onset of inflammation more pronounced and is a risk factor for allergy.

 

Although hair dye allergy is related to genetic susceptibility, the most important source is the allergen. 

PPD was recognized as a strong allergen long ago. my country’s "Hygienic Standards for Cosmetics" promulgated and used in 2007 stipulated that the content of p-phenylenediamine in hair dyes should not exceed 6%. 

The United States limits the content of p-phenylenediamine in hair dyes to 1% to 8%, and does not allow the use of p-phenylenediamine in eyebrow creams and mascaras to prevent corneal damage and blindness. 

According to research findings, the sensitization rate of Chinese people to phenylenediamine is about 10%, which is higher than the usual international sensitization rate of 2% to 6%.

 

When using hair dye, about 1% of p-phenylenediamine will be absorbed by the skin. PPD is a small molecule that can easily enter hair and hair follicles and move into keratin. 

The amine group (-NH2-) at one end binds to keratin, and the other end binds to dye molecules through an oxidant (H2O2), making the dye molecules attached on the hair, finish dyeing. 


Sensitization Mechanism of PPD Generates Free Radicals

Experiments have proved that the sensitization mechanism of PPD is that after entering the skin, under the action of an oxidant, it generates free radicals through oxidation, which stimulates the proliferation of skin keratinocytes and stimulates the production of allergic factors. 

A large amount of PPD can cause cell damage and death.

 

What are the symptoms of symptoms of allergic dermatitis?

The symptoms of allergic dermatitis are usually not very serious, mainly erythema spasm and edema of the scalp, forehead, and eyelids, lasting for half a month to 20 days. 

Although most are only delayed mild reactions, sometimes hair dye allergy can have serious consequences. 

If the hair dye gets into the eyes, it may induce allergic conjunctivitis and even eye damage. 

Some people suffer from purpuric nephritis and psoriasis due to hair dyeing, and some even pay the price of their lives for this. 

Beauty is important, but life is more important. It is not worthwhile to damage the quality of life or even lose life because of the love of beauty. 

After all, the love of beauty itself is improving the quality of life.


What are the precautions I should take before dyeing hair? 

Before dyeing your hair, you should test it first. Apply the hair dye behind the ears or elsewhere, and then dye the hair after confirming that you are not allergic. 

If you find allergies, do not dye your hair. Especially do not repeat dyeing your hair. 

Because research has found that multiple hair dyes with allergies can lead to more serious consequences. 


What precautions I should take when I shampoo my hair? 

When shampooing, be careful not to let the hair dye flow into the eyes, and it is best not to use too hot water, because that will make the scalp blood vessels dilate and absorb more PPD.

Therefore, dyeing hair is risky, so be careful when you love beauty!

He refused the offer of the top management of the BBC, but he is still hailed as Father of World Nature Documentary

"A spy robot monkey was accepted by the monkey group, and unfortunately fell off the cliff and died shortly afterwards. All the monkey group silently mourned for it." In this situation, the little monkeys felt like their children died.

 

Recently, this image of the animal world that is closest to human sadness along with 34 "animal spy robots" Wilderness Spy has blown up our circle of friends.

 

Some of them swim in the water, fly in the sky, run on land, and some are cute and peeping. They are so cute.


People also clapped their hands and praised the BBC filming technique, which is responsible for the conscience of the documentary.

 

In the past few decades, it is precisely because of the exhaustion of teams like the BBC that they have opened up the unheard of worlds for us.

 

David Attenborough, the Father of the World Nature Documentary

Among them, the most famous is David Attenborough, who is known as the father of the world nature documentary.

  

In more than 60 years, he led the team to record nearly forty natural history documentary programs.

His charming and magnetic voice became synonymous with BBC documentaries.

Under his impetus, the most advanced photography techniques have been applied to documentaries. He is also the only one so far.

People who have won the BAFA Awards (British Film Academy Awards, equivalent to the Oscars in the United States) in black and white, color, high-definition, 3D and 4K.

 

David Attenborough, Father of World Nature Documentary


The Sir Alex

The British royal family awarded him the title of knight for his contribution to the exploration of nature, and he was affectionately called "the Sir Alex".

 

He has personally inspected almost all known ecological environments in the world. Under his influence, hundreds of millions or even billions of viewers love nature.

 

Now, under his reputation, he is over 90 years old, who has won numerous awards, but he is still running in this career.

 


David Attenborough was born in London, England in 1926. His father was the president of a university in Leicester.

 

When he was young, he showed curiosity about nature, especially like collecting animal fossils and specimens.

 

Soon after, he turned into a small "museum", which was appreciated by everyone.

 

As a result, his love for nature is getting bigger and bigger like a snowball!

 

He has excellent academic performance since childhood, and after graduating from high school, he was admitted to Cambridge University to study zoology and geology.

 

David Attenborough, Royal Navy Soldier

After graduating smoothly, during World War II, he was naturally summoned by the Royal Navy and became a soldier.

 

After he was discharged from the army, he went to a publishing house by accident and became an editor of children's science books.

 

During that time, Attenborough held a stable salary and could free up some working time to do what he liked.

 

It didn't take long before he started to get tired of running around in the chores of the publishing house, and became increasingly disappointed with the works he had handled.

 

He quickly quit his job and submitted his resume to the BBC radio station on a whim.

 

He confidently enumerated his advantages as a broadcast host, and incidentally also wrote about his life experience.

 

What he didn't expect was that this position was the most competitive job at the time.

 

Because at that time, it was the golden age of radio broadcasting, and many people rushed in.

 

When there are more choices and no work experience, who do you reject?

After accidentally ate a closed door, Attenborough was a little frustrated.

 

But I didn't expect that the TV service department in the BBC, which had just started, fell in love with him and invited him to join this emerging industry.

 

At that time, like most British people, he had hardly watched TV, let alone TV shows.

 

But with a freshness, he not only readily agreed to participate in the three-month training, but also showed a faint smile after it was over.

 

It turned out that it was a training experience of a "blind" leading a "blind". Everyone is still exploring TV programs.

 

It might have been a pitfall for someone else, but he didn't think so, on the contrary, he worked harder and harder.

 

But at first, he was only the host of a few variety shows, and the influence was not big.


In the 1950s, most wild animals were almost isolated from humans, and there was no video record. People always stay in their imaginations about them.

 

Attenborough met the curator of a reptile zoo in London while hosting a show.

 

The two realized this situation and hit it off, planning to record the process of hunting animals in the wild.

 

When Attenborough proposed this idea to Taili, he immediately got everyone's support.

 

But it was very difficult to do this. He and his team had no previous experience with this kind of shooting.

During that time, they followed the zoo people to shoot in the wild almost during the day, and at night he wanted to check and understand the habits of the animals.

 

They may take a shot of an animal and wait for the whole day, or they may encounter an animal's surprise at any time and plan to take a bath.


During those difficult days, every scene, every line, every scene was passed by Edenburg himself.

 

The figure of David Attenborough busying around is no longer just a host.

 

With hard work day by day, in 1954 he hosted the show "Zoo Adventure" finally released.


These records of the impact of the London Zoo Reptile House's capture of wild animals in Africa and Indonesia immediately became a sensation, and people applauded.

 

Among them, Attenborough's handsome appearance in vividly and interestingly explaining the knowledge of wild animals is even more popular.

 

Although the pictures are black and white, and even some seemingly ordinary pictures, they are also very interesting under the vivid explanation of Attenborough.

 

This show quickly made him famous and received a large number of fans, but at this time he came to a rapid retreat.


It turns out that this film is actually a continuation of the heritage of the British Empire.

 

It's just that the naturalists who returned from all over the world back then were specimens of animals and plants, but now they are transported back to live exhibition animals.

 

In this process, apart from showing how human beings have great adventures, their attitude towards animals has not changed at all, but they are still regarded as playthings.


In 1957, he chose to resign and returned to university to pursue a PhD in social anthropology.

 

But just as he was about to graduate, the BBC still worked hard to invite him back to be the director of BBC Two.

 

But this time, his eyes are far more than just a job. He gradually focused on how to change the way he used to shoot and change people's attitudes towards nature.

 

In order to better express the content of TV programs, he also took the lead in trying to produce and broadcast color signals.

 

This also contributed to the popularity of color television in the UK.


However, in 1972, when the BBC promoted him to the position of director, he chose to put his life on the brakes again.

 

Attenborough decides to give up all that and go back to his old business and continue to shoot his beloved wildlife documentary.

 

For this reason, he has traveled almost every corner of the earth and experienced hardships that ordinary people can't imagine.


At that time, the transportation industry was not as developed as it is now, and many remote areas did not even have roads.

 

For the existing shooting tasks, he and his team carried a lot of things such as cameras, batteries, light sources, and film boxes, which was no less difficult than the European explorers in the great voyage era.

 

On the other hand, as early as the end of the 1950s, Austrian film producer Hans Haas proposed the idea of ​​underwater photography and successfully developed a waterproof case for underwater photography.

 

It was David Attenborough who risked his life to present marine life on television for the first time, shocking the world.

 

Compared with the difficulties encountered in these shootings, what Attenborough wants to change is people's attitude towards nature and awaken people's awe of animals.

 

If you don't shoot people and rely solely on the lens of nature to tell the story, is it possible to let the animals and plants themselves be the protagonists? 

But this simple idea has tested every aspect, including changes in shooting technology.

 

For example, since animals are the main characters, shooting at night has become an inevitable part.

 

At that time, Edenburg and his team had to use artificial light sources to provide the necessary light for the shooting, but they realized that such shooting would cause serious interference to their habits.

 

With the invention of the infrared camera, people can finally capture the most real life habits of these animals in the dark.


In addition, this idea has also completely changed the way that documentaries tell stories in the past, and there will no longer be people in the pictures.

 

In order to allow people to understand various animal habits more accurately, Edenburg and his team also consulted with scientists all over the world to select the latest and most interesting research results.

 

After overcoming many difficulties, until 1979, an epoch-making work "Life On Earth" came out.

 

This set of films immediately received numerous fans as soon as it was released, and was hailed as the pioneering work of modern natural history documentaries.


But Attenborough is not satisfied with this, always looking for the latest shooting methods to show the true nature of nature.

 

As a result, his life in pursuit of nature has also become a model of lifelong learning.

 

Whether it is new photography formats such as color, high-definition, IMAX, 3D, 4k and computer-assisted virtual reality, or new shooting methods such as hot air balloons, helicopters, drones and submersibles, he always hopes to learn in the first place And adopt.


The Living Planet

Attenborough has released the two films "The Living Planet" (The Living Planet) and "The Trials of Life" non-stop, which together are called the "Trilogy of Life".

 

Blue Planet

Since then, his series of films such as "Blue Planet" and "Pulsation of the Earth" have also integrated the latest shooting technology and achieved greater success.

 

Life Series

In 1993, he was supposed to retire in his old age, but he still ambitiously planned a more ambitious set of "Life Series" DVD encyclopedias, which will present the audience in more detail after classifying natural creatures.

 

So over the past two decades, there have been: "The Fairy Tale of Ice and Snow", "The Private Life of Plants", and "The Blue Planet", which cover all the types of animals and plants on the earth.

 

Attenborough not only likes to shoot natural history documentaries, but also a world-renowned environmentalist who has devoted his life to protecting the ecological environment of the earth.

 

Blue Planet 2

In the process of participating in the filming of "Blue Planet 2," when he saw an albatross out looking for food for his children, he returned with a stomach full of things, thinking it was a squid, but it was actually plastic garbage.

 

He was deeply worried about the future living environment of marine life, and he used his influence to appeal to reduce plastic waste.

 

From 26 to 91 years old, from Zhu Yan with green temples to gray hair, for him, shooting documentaries is no longer just out of love.


The driving force of his life is more:

He felt that we must pass on the world to the next generation and truly express our concerns about the fate of the natural world.

 

It can be said that: born of sorrow, die of happiness.

In addition to cute Giant Pandas, China also has these strange and rare animals

Deer have horns on their heads and carnivores have canine teeth. This is the subjective impression of most people on these 2 types of animals. 

Unfortunately, this impression flow is really wrong. Although it is widely distributed, the overall number of great bustards is very rare. There are currently less than 1,000 in China, and they have been listed in China's Red Book of Endangered Animals and are nationally protected animals.

Little Molu: Rabbit with Long Fangs"

 

Deer have horns on their heads and carnivores have canine teeth. This is the subjective impression of most people on these two types of animals. Unfortunately, this impression flow is really wrong. 

Not to mention that the biggest difference between carnivores and herbivores is whether there are cracked teeth (the collective term for the last premolar of the upper jaw and the first molar of the lower jaw). 

Even in deer animals, many have no horns on their heads, but canine teeth. One of the very developed members, the Little Molu is one of them.

 

The deer belongs to the Artiodactyla deer family, with a body length of 43-50 cm; a weight of 2.5-4.5 kg, which is about the size of a rabbit.
