I Have a Safari Park

After dinner the next morning, Fang Ye met with the civilian staff to discuss the design of other exhibition boxes. He was really too busy to find so many exhibition boxes alone, and there were too many materials to find.

The civilian staff collected a lot of information for a while, and they all came in handy at this time, including the original habitat of various animals, suitable temperature and food, and put forward their own ideas and opinions.

In addition to the general exhibition boxes, there are also some larger exhibition areas in the amphibious crawling hall, with an area of ​​20-50 square meters!

The two currently prepared are for Zhuyeqing and the other is for Chinese giant salamanders.

The amphibians and reptiles that are also very famous in China and have more distinctive characteristics, of course, should have some sort of exhibition area for them. Although Zhu Yeqing is small, it is not a waste to use a large exhibition area.

The Chinese giant salamander is commonly known as the baby fish. Although it is called a fish, it is actually not a fish. It is the largest existing amphibian with a body length of up to two meters. It is one of China's national treasures.

The earliest fossils discovered are hundreds of millions of years old, and can be said to be living fossils in the animal kingdom! The giant panda, also known as a living fossil, has only 8 million years of history.

Compared with ordinary frogs and toads, giant salamanders are more picky about the living environment. In nature, the habitats where giant salamanders are found are dense forests with vegetation coverage as high as 80%-90%. The surrounding areas must have sufficient water sources and mountain streams. The giant salamander needs to rely on moist skin to assist breathing, and the dense jungle can not only block the sun, but also create a humid air environment to prevent it from suffocation due to dry skin.

Even if the adult giant salamander has the ability to climb on land, it only dares to move on the land close to the stream. Therefore, mountain streams and running water are the necessary conditions for the survival of this amphibian like giant salamander!

In addition, the water temperature of 16-28 degrees is the most comfortable and comfortable for the giant salamander. When the water temperature is lower than 4 degrees or higher than 33 degrees, the food intake of the giant salamander will decrease, the movement tends to be sluggish, and the growth is slow.

The giant salamander is also very particular about the geology and topography of its habitat. It likes to live in limestone areas. Under the long-term erosion of river water, these areas will produce many... Chapter 182 The clear stream of the giant salamander (page 1/4). The natural karst caves, underground rivers and caves that return water. Adult giant salamanders generally live alone. Once they identify a cave, they will not move easily.

These caves have not only become the best refuge for the giant salamanders, where they can take shelter from the light, rest and avoid natural enemies, and they are also the back gardens for their incubating offspring. It is precisely because of this specific hidden breeding place that the giant salamanders have been passed down from generation to generation for hundreds of millions of years. year.

Moreover, the giant salamander also has high requirements for water quality. It is not an exaggeration to say that it has a cleanliness. The water suitable for life must be clear and clean and rich in minerals. The dissolved oxygen in the water must not be less than 5 mg per liter. The larval growth stage, the water oxygen content It is even higher than 5.5 milligrams per liter, which is close to the standard of human healthy drinking water.

Dense forests, humid air, suitable temperature, hidden caves, flowing river water, clean water quality, and abundant food are basically indispensable for giant salamanders.

Because of the harsh requirements for the living environment, the giant salamander is also regarded as an environmental indicator, and is called the "canary in the coal". If you can see the giant salamander in the wild, it means that the environment here is quite good, basically it can It's called a paradise.

However, with the increase of human activities and environmental pollution, the number of wild populations has dropped sharply, and they are already critically endangered, and are listed as national second-level protected wild animals.

With the breakthroughs in artificial breeding technology of Chinese giant salamanders, giant salamanders were even put on the table, and many protected areas also purchased juvenile salamanders from giant salamander farms for release.

It seems that the protection situation of giant salamanders is very good. In fact, a study on giant salamanders in recent years shows that the Chinese giant salamander population contains at least 5 different evolutionary branches, that is, 5 different subspecies. The reintroduction has greatly destroyed the genetic diversity of giant salamanders, and wild giant salamanders may be extinct silently.

Another typical example of genetic pollution hazards is the cross between domestic yak and wild yak. ​​Genetic pollution caused by hybridization will make the wild yak smaller and lose some of the characteristics of adaptation to plateau cold tolerance and low oxygen content, and can choose to survive. The smaller the scope will bring about a series of effects.

Therefore, the giant salamander is exhibited...Chapter 182 The clear stream of the giant salamander (page 2/4),. It is not only to display this ancient living fossil, but also has a high protection and educational value. It is very alarming to see the crisis facing the giant salamander.

First of all, as an environmental indicator, giant salamanders are highly sensitive to climate change and environmental pollution that can lead to species extinction. If they go first, then other species will gradually follow in their footsteps.

Another display board about genetic pollution can be introduced, telling tourists the harm of genetic pollution, and they cannot be released randomly! It must be released under scientific guidance, otherwise it is not doing good, but doing evil.

The science exhibition board in the raccoon exhibition area described the invasion of species caused by the release, and the combination of the two has a better effect.

Designing the environment of the exhibition area for the giant salamander naturally imitates the mountain streams, waterfalls and pools in the wild.

The exhibition area of ​​the giant salamander is a long and narrow side with a width of 2.5 meters~www.readwn.com~~12 meters long. A crooked creek is first arranged inside. The shallowest part of the stream is 20-30 centimeters, and the deepest pool is one meter. deep.

A layer of small pebbles was laid on the bottom of the stream, and some large pebbles were laid on it. At first glance, the stream washed over the years, erasing the edges and corners of the stones, one by one, round and smooth.

The water circulation system is installed to keep the water body purified. The cold water system simulates the natural water temperature and is controlled at around 18 degrees. The spray, fog, and lighting systems simulate natural rainfall, morning fog and other weather.

The stream is the tourist side, so that visitors can get a close view of the water profile below the water level. The giant salamanders move in the extremely clear and transparent water, and there will be some medakas in the water.

The medaka is a small, silvery, translucent fish. It is also sensitive to changes in water quality and likes clean water. It is just the neighbor of the giant salamander.

On the opposite side of the exhibition area is the black wet river bank. There are mountains and rocks. Below a dripping rock wall, there is a dark cave recessed, like a mysterious cave, which can be used as a residence for giant salamanders.

Choose the slow-growing calamus, ferns, palm bamboo and moss at an altitude of about 700-1200m in Hunan as plants, plant some scattered on the rock wall, and place a few pieces of driftwood on the bank of the stream.

......Chapter 182 The clear stream of the giant salamander (page 3/4),. The trickle water continued to drip down along the rock wall, sometimes slowly, some dropped directly into the water, some hit the emerald green leaves of ferns, the palm bamboo cast mottled shadows in the water, and the giant salamander and the medaka were extremely clear. Swimming in the water and playing, life in such an environment will surely be extremely comfortable.
