Yes

The brown rat is the most widely distributed, most harmful and most successful mammal in the world. It is a typical domestic pest rat, the ancestor of the laboratory rat, and the rat of the middle finger of the zodiac. It is a consensus that it is considered an invasive species in Europe, the United States and Australia, and an undoubted invasive species in Xinjiang, China.

However, it may not be appropriate to count other inland areas outside of Xinjiang as invasive species. Some articles generally say that the brown rat originated in Asia and invaded China, but China has a vast territory, diverse climates, and many geographical barriers; At the same time, Asia is also divided into east, west, north, south, and middle, which needs to be discussed on a case-by-case basis.

What are Invasive Species?

Invasive species are first and foremost alien species and cause harm. The time scale for the first appearance of species should be ecological, and most invasive species were formed around 500 years. It is estimated that the distribution area of many species has changed greatly in 8000 years, and most of them have not been recorded, and they have long been "naturalized" in the new area to achieve ecological balance, so the general large-scale time invasion has no practical significance.

The more harmful the invasion, the more "newcomers to the invasion" often cause new harm in the invasion area.

But in any case, the brown rat is considered an ancient population in the interior of our country, and there is a history of existence for thousands of years and tens of thousands of years. The brown rat spread to Europe, the United States and Australia in 500 to 300 years and is an invasive species, but it seems inappropriate to say that it is an invasive species in the interior of China. The brown rats around the world may have invaded the brown rats in China.

Yes

Rattus norvegicus is a global domestic pest and one of the world's "Top 10 Invasive Species". It was only about 300,500 years ago that this rat gradually spread from China and its surrounding areas to Europe, the Americas, Australia and other places, and successfully invaded 90% of the world's islands, resulting in the extinction of at least 60% of the islands of birds and reptiles.

The brown rat is known as a rat with special skills, and its movements are agile, and when it moves, it usually moves along the corners of the root wall of the wall. You can walk horizontally or vertically on wires, ropes, heating pipes, cables, or climb straight up on rough brick walls. Adult brown rats can jump up to a height of more than 77 centimeters and jump outwards and downwards for a distance of more than 2 meters.

It is an excellent swimmer, both above and below the water. It can dive for fish, and can easily dive over the backwater bend of the toilet.

The brown rat also has a strange name - Norway rat. It is very common to say that the brown rat came from Norway. In 1769, the British zoologist John Beckenhot gave the brown rat the scientific name "Norway rat", because he also believed that the species migrated to England via Norwegian ships in 1728.

There have been many evaluations of the brown rat, among which there is a saying "the brown rat, go all over the world" can best reflect its characteristics.
