Why did the 15 elephants migrate north? Why can t they be allowed to stay in the north to evolve?

Elephants belong to the order Proboscidae, there are only one family, two genera and three species, namely elephantidae (scientific name: elephantidae), African elephants and elephants, there are two kinds of African elephants: common African elephants (also called savannah elephants or shrub elephants) and African forest elephants, and there is only one species of elephants in the genus Elephantidae (also called Indian elephants).

Asian elephants are actually widely distributed in the Central Plains of our country and the Qinling Mountains, 7,000 years ago elephants were almost distributed in most parts of China, and then the elephant population continued to move south, climate changes, human activities have a huge impact on elephants, less than 3,000 years, most places have no elephants. The Central Plains used to be suitable for elephants to survive, but the Xiaoice Age is approaching, the temperature is lowering, elephants like warm and humid environments, many areas in the north and south are no longer suitable for elephants to breed, and slowly only places with perfect tropical ecosystems can become elephant habitats. This time, the 15 elephants are Asian elephants, and why they went all the way north is actually related to food.

In terms of ecological governance, with the attention of the state, many places in China have shown a general trend of improvement. The 15 elephants come from the Xishuangbanna Reserve, and of course there is no doubt about the conservation of animals in the reserve, but the number of elephants in the better environment is growing, even exceeding the limits of the reserve. Elephants are big, but the eating efficiency is not high, in fact, less than half of the food digested, resulting in food waste, food needs, elephants weigh 4 tons of energy consumes a lot of energy, 16 hours a day in eating.

This season in Xishuangbanna is the time when herbaceous plants are not green, and a large number of plants are still taking root and sprouting, and they will not be completely vigorous until summer. However, the increase in arbors and plants and the decrease in herbaceous plants in the Xishuangbanna Nature Reserve have reduced the total amount of food for elephants, making them unable to fill their stomachs, and elephants naturally have to find new habitats. In addition to the lack of food being a big problem, the elephants may also be related to the change in weather.

If you look at the trajectory of the elephant herd, you will find that the elephants are in a state of disorderly wandering, and experts say that perhaps because of the inexperience of the elephant leader, the elephant herd has been led astray. Herds are usually led by a female elephant who may not have had time to become familiar with the skills before she encounters a food crisis and has to lead the herd to forage for food, which leads the herd hundreds of kilometers away, making it even harder to find a new habitat. Of course.

The continued northward migration of elephants has of course taken away the influence of people, who used to see elephants fighting to drive them, but now people don't hurt elephants, so elephants have become emboldened and dare to run out to eat crops. With a stable diet**, elephant rafting trips are also facilitated.

Of course, the experts still hope that the elephants will return to their original habitats, after all, the elephants will be weakened because of the climate adaptation, so the experts also hope to guide the return of this group of elephants as soon as possible, after all, the north is not a suitable habitat for elephants!

It is because this place is not suitable for survival that they move north. This is because staying in the north will destroy things in the north, and it will be especially difficult for them to survive in the north.

The 15 elephants migrated north because their habitat was shrinking and there was less and less food to eat. The reason why they are not allowed to stay in the north to evolve is because there is no suitable habitat for them in the north, and it is not conducive to the development of the population.

It's because these elephants want to find a place where there is plenty of food, mainly because there is no food in the north, so they can't live here at all, and the temperature is relatively low.

This is because they want to migrate to other places to live, and there is a relatively large amount of environment and food in other places, and if they stay in the north, there is a high risk of extinction.

Mainly because there is nothing to eat in the place where they live, they migrate north, and they cannot stay in the north because after winter, there is nothing for elephants to eat.

It is reported that judging from the location of the elephant herd and the characteristics of its recent activities, it seems that they are going north. In fact, this is not the first elephant to come out of the reserve. Surveys show that most of the wild Asian elephants have left their original nature reserves.

Most wild elephants roam outside the reserve. However, this does not mean that the original nature reserve has been destroyed, on the contrary, the wild elephants have come out of the reserve precisely because the surrounding environment has improved. However, the protection efforts in the reserve have been continuously increased, and the forest canopy density has increased significantly, and the forest coverage rate has increased from 1983 to 2016, resulting in the gradual succession of understory plants such as wild plantain and Zongye reed, which are the main foods of Asian elephants, to inedible woody plants.

The decline in the number of plants available to Asian elephants is forcing elephant herds to move outside protected areas to feed. Outside the reserve, the grain grown by the farmers is delicious.

The reasons for elephant migration are: 1. Finding a suitable habitat: In recent years, due to the rapid growth of the population and the continuous expansion of human activities, the habitat space of elephants is getting smaller and smaller, which to a certain extent leads to some elephant herds going out to find new habitats.

2. Climate change: In the rainy season, dry season and the process of temperature change, some African elephants will migrate randomly. 3. Elephants themselves have the ability to migrate over long distances

Elephant migration is an instinct, almost all herds will migrate, the difference is the length of the migration distance, the elephant will migrate to different places in different seasons.

Elephant migration is a normal phenomenon for several main reasons. The first reason is climate change, elephants have a strong sense of climate, and if there is a large climate change, elephants will migrate and look for a more suitable climate environment. The second reason is to find suitable habitats, and if habitats are damaged, they need to migrate to find more suitable habitats.

The third reason is the lack of food and the need to look elsewhere for abundant food.

I think it may be due to meteorological reasons, or it may be the ecological environment, but the exact reason is not yet known.

The reason for the university migration is because of the change of seasons, because the food will be different in different seasons, so it is necessary to migrate to ensure food.

1. The people take food as the sky, and the same is true for elephantsWhen food is scarce in their habitats, elephants run away from hometo find new food sources.

2. The ecological environment of Banna area has undergone great changes, this is a rainforest area, the rainforest development conditions are very harsh, different from the development of the rainforest area of the Congo River Basin in Africa, the winter half of the year in Banna is the dry season, because the Qinghai-Tibet Plateau affects the atmospheric circulation, and the air flow from the south branch attracts the water vapor of the Indian Ocean to the north, just passing through the Banna area, there is winter precipitation.

However, in recent years, either El Niño or La Niña, one after another, has led to the instability of the southern branch airflow, which has affected the precipitation in the Banna area throughout the yearDegradation of rainforests or low productivity of grasses on the ground has led to a squeeze on elephant habitat, the range is getting smaller and smaller, and finally they choose to run away from home.

The panic caused by elephants in Yunnan because of crustal activityRecently, Dali has had a grade**, and some small ** often occur in Yunnan in the early stage, judging from the elephant herd's insistence on going north, it seems that it is calling from afar. The elephant is an advanced mammal with a higher IQ. We humans have nothing to fear, but for elephants, they may have special inductions to move their families.

Occurrence of magnetic storms。The earth is in the solar system and is deeply affected by the sun, and solar activity will affect the earth's magnetic field, causing the earth's magnetic storm phenomenon. The elephant herd began to move north in March last year, and why did it go north, not to the east or west, as if it was carrying a navigator and setting the destination, then geomagnetism is the reason why the elephants are guided north.

Global warming, the climate zone shifts northwardThe habitat of elephants is the tropical rainforest, and the northward movement of the climate zone is not a matter of three or two years, even if the world is warming, this small change will not make the elephant unable to adapt, and choose to run away from home, unless the elephant is sensitive. The further north we go, the worse the rainforest environment becomes, the more difficult it is to get food, and elephants have existed for millions of years in terms of biological evolution, and the species has a certain degree of stability.

There are many theories, and I feel that as the range of human activities becomes larger and larger, encroaching on the territory of many wild animals, wild animals are looking for better habitats. Elephants are like that.

1. Finding new habitats: Because the breeding of Asian elephants in Yunnan is almost not constrained by natural predators, and the population of Asian elephants is gradually increasing, once the number exceeds the range of habitat accommodating relatives, it will spread. The reason for the northward migration of Asian elephants may be to find new habitats.

2. Looking for food: Now is the time when the wild Asian elephant food is scarce, and the elephant knows that humans will no longer harm it, so they go out of the reserve and enter the human farmland to forage for corn, bananas and other crops.

3. Influence of geomagnetic storms: Animal migration is related to many factors, one of the key factors is the earth's magnetic field. Many animals on Earth are guided by geomagnetism to carry out long-distance migrations in a seasonal cycle.

The disturbance of the magnetic field will interfere with the migration process of the animal to a greater or lesser extent.

Introduction: According to monitoring, the herd consists of 6 adult female elephants, 3 male elephants, 3 sub-adult elephants, and 3 juvenile elephants. The elephant herd traveled all the way north from its hometown of Xishuangbanna, migrating nearly 500 kilometers in Guangzhou, almost across half of Yunnan Province.
