Thekey difference between exotic and endemic species是外来物种是属于其他地区但在另一个外国地区引入的物种,而特有物种是属于它们特别发现的物种。
在生物学分类中,一种物种是一组具有共同特征且能够杂交的相关生物体组成的生物。这种物种的生物学概念通常用于生物学和相关领域。但是,那ecologicalspecies concept describes species as a group of organisms framed by the resources that they depend on. These species help to define an entireecosystem。异国情调和特有物种是生活在生态系统中的两种非常重要的物种。

什么是外来物种?
Exotic species are species that belong to some other area but are introduced in another foreign area. These species usually live outside their native geographical region. Most probably, these species have arrived in a foreign region due to deliberate or accidental human activity. Normally, non-native species have various effects on the local ecosystem. If the introduced species become established and spread beyond the place of introduction, they are considered naturalized.
The human-caused introduction of species is completely different from biological colonization since biological colonization is due to natural factors such as storms and rafting. The impact of introduced species on a local ecosystem is highly variable. Some have a substantial negative impact. These are also called invasive species. Other species have no negative effects or only minor impacts. Moreover, in scientific research, some species have been introduced internationally to combat pests. They are known as biocontrols. They may be considered beneficial as an alternative to pesticides like in agriculture. Furthermore, the effects of exotic species on natural environments have gained much scrutiny from scientists, governments, farmers, and other stakeholders over the years.
什么是特有物种?
Endemic species are the species that belong to an area where they are particularly found. These species are those found only in just one region and nowhere else in the world. For example, kangaroos are endemic to Australia. But when kangaroos are spotted outside Australia, this is due to the human-caused introduction.
There are some othermarsupialsthat are endemic to Australia and its surrounding islands. One such animal was the Tasmanian tiger that was endemic to Australia, Tasmania, and New Guinea. Now, it is an extinct carnivorous marsupial. Furthermore, the Cape sugarbird is found exclusively in southwestern South Africa. Therefore, it is endemic to that particular region. When it comes to plants,Cyctisus aeolicusis an endemic of the Italian flora. A rare alternative term for endemic species is “precinctive”. This applies to species that are restricted to a defined geographical region.
What are the Similarities Between Exotic and Endemic Species?
- 异国情调和特有物种是生活在生态系统中的两种非常重要的物种。
- Both species are described in the ecological species concept.
- These species are sometimes beneficial to the local ecosystem.
- 这两种物种都有繁殖和传播的能力。
异国情调和流行物种有什么区别?
Exotic species are species that belong to some other area but are introduced in another foreign area while endemic species are species that belong to an area where they are particularly found. So, this is the key difference between exotic and endemic species. Furthermore, exotic species may have a substantial negative impact on the local ecosystem, while endemic species do not have a negative impact on the local ecosystem.

摘要 - 异国与地方性物种
在生态物种概念中,物种主要是两种类型:外来和特有物种。外来物种是属于其他地区但被引入另一个外国地区的物种。特有物种是属于特别发现的地区的物种。因此,这是异国情调和特有物种之间的关键区别。
