Chapter 510 (1/2)

The urban animal exhibition area and the local animal exhibition area are still in the tentative stage.

But the future is certain.

The two exhibition areas have similarities, but they are different.

The urban animal exhibition area mainly shows the contradictions between people and animals and how to live in harmony in the urban space.

The local animal exhibition area is based on the changes of local animals near the sea.

What animals once lived near the sea, what is the current situation, where they live, how many, whether the population is decreasing or increasing, and if they disappear, why?

Let tourists know that the destruction and protection of the environment take place on the land around them, not far away from themselves.

We need to do some research on the current distribution of animals in Linhai, find the county chronicles, or ask the elderly, and sort out the clues of animal changes through their memory.

Fang Ye thinks it still needs more learning experience. At present, the construction time is not too ripe.

From raccoon dogs to wild boars.

Before, because of the milk tea wild boar, some infrared cameras were arranged in the villages and towns around Linhai, and the video materials were handed over to Wang Yan and his team for research, so they also had some understanding of the distribution of wild boars.

The number of wild boars near the sea is relatively small.

The distribution survey has made it clear that the measures to prevent wild boars in villages and towns have been arranged, and a lot of publicity has been carried out on wild boars. The preparations are ready, and it is time for the black cyclone Meimei to release them.

Fang Ye remembered something: ”I saw a news yesterday that the number of wild boars in Huangshan, Anhui increased sharply. Now we are carrying out wild boar prevention and control, preparing to hunt wild boars and regulate the number of wild boars. It is estimated that we will see the news of wild boar disaster from time to time. ”

Wang Yan said: ”no way. There is no tiger to control the number of wild boars. The impact of the disappearance of animals has never been reflected immediately.

I think you have a flock of pigeons at the gate of the zoo, as well as the exhibition board of traveling pigeons. Traveling pigeons are a typical example. ”

Fang Ye is all ears. He knows about the extinction of traveler pigeons, but the specific impact is really unclear.

Seeing that he was interested, Wang Yan said, ”didn't this traveling pigeon become extinct in 1914? Before extinction, people estimated its number at the level of 10 billion. Flying over the top of my head, the sky will darken like a dark cloud.

The short-term extinction of passenger pigeons seemed to have little impact. People didn't know what it meant until 84 years later.

There are a large number of oaks in America. These oaks can be divided into big and small years. The oaks in a forest will bear fruit at the same time to avoid eating all the acorns.

After a long period of extinction of the traveling pigeon, it suddenly caught up with an oak new year. The ground was full of acorns. In the past, the traveling pigeon was the main consumer of acorns. Now the traveling pigeon does not exist, and there is an outbreak of mice.

With the urbanization of various places, mice not only broke out in the oak forest, but also began to break out in the city.

House mice carry ticks. If the weather is too cold in winter, the ticks will die and can't overwinter.

However, with the climate warming, the distribution area of mice has expanded, and the distribution of ticks has been expanding. Therefore, with the outbreak of acorn and mice, Lyme disease has become a very common zoonosis in North America.

Lyme disease is mainly transmitted through tick bites. It can cause joint pain, loss of language ability, and even respiratory disorders and death in severe cases. This is a concept we are talking about, the time lag of ecosystem. ”

Fang Ye couldn't help thinking of a sentence. His unfortunate childhood needs to be cured for a lifetime.

In fact, the same is true for the ecosystem. Some serious damage requires a long time and great efforts to recover, and may even never recover.
