: 664 Arrival of the Expedition, Taxus


For example, Professor Dai Jixian, academician of the Chinese Academy of Sciences, internationally renowned ornithologist Kavin Weissink, internationally renowned biologist, Chen Rui's best friends, Earl Hill, etc., because Chen Rui is often in the .q / q group Send some novel pictures of biological species. In order to get the latest first-hand information, there are many biologists around the world joining this group.
The picture of the North American travelling pigeon shocked all the biologists in the qq group. Professor Dai Jixian was so excited that he couldn't wait to fly from Yanjing to Daqingshan immediately. Kavin Weissink excitedly asked his assistant to book a ticket. When I went to China, Earl Hill wanted to contact Chen Rui for the first time. The survey team of Li Jiayi's grandfather Li Haichuan became even larger. A team from the American biology community boarded a plane to China .... .. Biologists all over the world can't wait to see the North American travelling pigeons, a well-known bird that has long been identified as extinct.
----------
Chen Rui and Li Jiayi spent the first night in Daqingshan.
The next day, the two got up early in the morning. The air in the forest was very fresh, the sun had not yet come out, the dew was heavy, and the air was very wet. The early birds had been screaming on the tree, playing a pleasant sound. Early morning in the jungle.
After the two washed a little in the stream, Li Jiayi received a call. The expedition team had already entered the mountain and would arrive here at about 9:30 in the morning. It was about 2 hours away.
The two didn't go anywhere, so they waited for the delegation here.
I heard that there were many delegations, with dozens of them. In addition to Chinese biologists, there was also a team from the United States who arrived overnight. It is said that there are some official backgrounds in the United States. Many biologists around the world have entered Daqingshan one after another, looking for North American travelling pigeons in Daqingshan.
At about 10 o'clock, Chen Rui and Li Jiayi waited for the delegation led by Li Haichuan. There are more than 40 people, including famous Chinese biology professors, foreign biologists who speak English, and their assistants. With a large backpack, carrying video equipment, and panting, his face was already sweating, and he entered the mountain from morning on. Up to now, climbing on the rugged Daqingshan Mountain Road has been very hard.
"Hello, ruichen, I'm Milston Denver from Harvard University."
"Hello, Professor Milton."
"Hello, Professor Dai."
...
After introducing each other.
"Let's take a rest first, and wait for me to take you to look for Dasao and the traveling pigeon."
"It's very rugged and steep, and the forest is dense and dense. It can be said that it is an old forest in the deep mountains. No wonder the Daqingshan giant panda subspecies, the big salamander and the traveling pigeon have been found in this mountain. Trail, I will apply to the state for nature reserves. "
"I am an old friend in the United States. I heard that I found a travelling pigeon in Daqingshan. I have made 4 or 5 phone calls and made sure to me if I actually found a travelling pigeon."
...
Everyone took a break and drank some water. After eating something, I can't wait to start.
Chen Rui took everyone to the cave in the upper stream.
"We have roughly counted the number of big that Jiayi and I found here, about 30,000 to 35."
Chinese scientists took out the camera and began to take photos of the big salamander in the stream. I took out a few and put them in a water tank.
Under the guidance of Chen Rui, scientists found the largest giant salamander in a cave again. After measuring, it was found that the body of this giant salamander reached 2 meters 14 in length. He weighs 75 kg and is already 150 years old, setting the Guinness World Record for 'Ben Ben'.
It seems that biologists from the United States did not show much interest in Dashen, and kept asking Chen Rui about the process of discovering North American travelling pigeons, and showed great interest in North American travelling pigeons.
It was about noon, and the research on Dasao came to an end.
In the afternoon, Chen Rui took everyone into the jungle.
About two hours later, I arrived in the woods where the North American travelling pigeon was found yesterday.
"Yesterday, we found the trail of the traveling pigeon here." Chen Rui pointed to the dense woods in front. "The traveling pigeon stayed in this forest for about 4 or 5 minutes, then flew away and headed over there. Fly away in that direction.
"Thank you very much," said Milton Denver to Chen Rui. "We want to stop here."
"can."
Everyone entered the forest, and found some feathers and feces left by the traveling pigeons on the ground, put them in bags, and the discovery of the feathers and feces of the traveling pigeons gave the scientific research team more confidence in discovering the traveling pigeons.
Look in the direction that the pigeons flew away yesterday.
Walking and walking, suddenly Chen Rui stopped and turned his head and said, "Let's stop, and when I step back, I find something."
"Jiayi, give me a trekking pole."
Li Jiayi handed the trekking pole to Chen Rui.
Chen Rui took the trekking pole and slowly moved the trekking pole into the grass. Suddenly, he pressed it sharply and held down a triangular snake head.
There was a poisonous snake hidden in the grass in front.
The head of the poisonous snake is triangular, shaped like a soldering iron, the tail is white in color, and the body is black-brown. It is mixed with tiny yellow-green or rust-colored dots, forming a fine mesh impression. The clusters gather to form a lichen-like spot, which is equidistant from the dark brown, runs through the body tail, ...
"This is a Mangshan iron tip," said a Chinese biologist in the expedition with some surprises.
Chen Rui knew him. He came from Yanjing and called Li Qingming, a famous Chinese biologist, herpetologist and ornithologist. He had very deep research on snakes and birds. Yesterday he heard that he had discovered the North American Travel Agency in Daqingshan. The pigeons couldn't wait to follow the delegation.
Li Qingming went on to say, "This is the largest poisonous snake in the world. Unlike other pythons, the Mangshan iron tip belongs to the venomous snake, belongs to the family Aceridae, the fierce giant cricket, the weird rattlesnake, and the charming bamboo leaf green snake are its cousins. .
Because the head of Mangshan's iron is large in size and the amount of venom secretion is large, once it is bitten, its snake venom quickly attacks the blood with the human body, and in a short period of time, it causes death ....
Most of these snakes are distributed in Lake Mangshan. In Mangshan, the iron head of Mangshan is considered to be the direct descendant of the legendary Fufu son-in-law, 'Little Green Dragon', ..., Mangshan In addition to the lake () south Mangshan forest area, but also in the lake (North), Guang (East), it is also rare, the number is only in China, the whole China is only about 300 to 500, Less than the number of giant pandas, known as 'giant pandas in the snake kingdom'.
Due to its scarcity and scientific research value, it has been fired to more than 1 million yuan on the black market. It was a very pleasant surprise to find the Mangshan iron tip here. "
Everyone took out the camera and took a few sets of photos. Then, Chen Ruifang was born.
After discovering the Mangshan soldering iron head, everyone's interest was obviously a lot higher. Daqingshan is really a treasure trove of biological species, subspecies pandas, giant salamanders, Mangshan soldering iron head, and the most cherished North American travelling pigeon ..... . The deeper we go into Daqingshan, the more weird creature species will be discovered, everyone is looking forward to it.
Although Chen Rui discovered the North American travelling pigeon in the forest yesterday, a 'travel' in the travelling pigeon shows that this bird's habits are not limited to living in a certain place like many land creatures. The North American travelling pigeon It has to fly everywhere, so it is very difficult to find the North American travelling pigeons in Daqingshan. You have to try your luck. I guess everyone has this in mind.
More than 40 people stayed in Daqingshan for 3 days, and they have already gone deep into Daqingshan, and there is still no trace of North American travelling pigeons.
However, many precious biological species were found, such as Metasequoia, wild ginkgo trees, Davidia involucrata, clouded leopard, macaque, red panda, etc., and a whole yew forest, which surprised everyone on the expedition.
You know, the yew is very rare and precious. The yew is an ancient tree left over from the Quaternary Glacier. It has been on the earth for 2.5 million years. Due to the slow growth rate of the yew, it has grown from seed to ground. The tree takes 100 to 250 years, and its number is very small. The yew is called 'national treasure' in 42 countries with yew in the world. The United Nations has banned logging and it is a veritable 'plant panda'.
In recent years, the yew has also become a popular star in the botanical world because it can refine paclitaxel.
Paclitaxel is a worldwide recognized anti-cancer agent ~ EbookFREE.me ~ In the year, two American chemists successfully isolated a substance from the trunk of Taxus chinensis, named paclitaxel.
In 1992, paclitaxel officially passed the FDA's fda certification and was approved for marketing.
In China, in the summer of 1992, the first wave of yew bark battles started in the northwestern region of Yunnan (Yunnan), Yunnan, and a large number of businessmen flocked to the forest to buy yew bark ...
In the United States since 1992, paclitaxel has been hailed as one of the top three anti-cancer drugs in clinical use, and its value has also increased year by year. The US manufacturer holding the patent will increase the price of paclitaxel, reaching US $ 3 to 4 million per kilogram ....... Paclitaxel has become the most promising drug, and paclitaxel investment has spread worldwide. heat.
The content of paclitaxel produced in China is more than 98%, and the export price is generally 800 yuan / gram RMB. Each gram of paclitaxel is made into 33 g injections, each containing about 30 ml of paclitaxel. For RMB, each gram of imported paclitaxel is equivalent to RMB 80,000, which is more than 600 times the price of gold. (To be continued.)
