What is the Difference Between an Introduced Species and an Invasive Species

Thekey difference between an introduced species and an invasive speciesis that an introduced species is a non-native species introduced into an environment by human or other means, while an invasive species is an introduced species that is spread beyond the place of introduction, causing damage to nearby species.

Introduced species and invasive species both are non-native. Non-native species are those that do not naturally occur in the native environment. They are introduced to the native environment as a result of deliberate or accidental human activities. The impact of non-native or introduced species is highly variable. Some, such as invasive species, have a substantial negative effect on the localecosystem.

What is an Introduced Species?

An introduced species is a non-native species introduced into a native environment by human or other means. It is also known as alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species. Usually, an introduced species lives outside its native distributional range. It arrives at a native environment by human activity directly or indirectly, either deliberately or accidentally. It can have various effects on the local ecosystem.

Introduced species are further divided into subgroups; invasive, acclimatized, adventive, naturalized. Invasive species can cause ecological, economic, and other damages to the local ecosystem. An acclimatized species changes physically or behaviorally in order to adjust to its new local environment. An adventive species is an introduced species that is not permanently established. Moreover, a naturalized species does not need human help to reproduce and maintain their population in the new local environment. Furthermore, some species have been introduced to a local environment deliberately to combatpests. An example is a biocontrol in agriculture. Therefore, the effects of an introduced species on the natural environment have gained much scrutiny from scientists, governments, and farmers recently.

What is an Invasive Species?

入侵物种是一种引入的物种，扩展到了引入的地方，从而损害了附近的物种。入侵物种被广泛或迅速传播，并对当地环境，人类健康，经济和其他有价值的资源造成伤害。科学家基本上考虑了一种基于其传播和繁殖而不是可能造成的其他危害的物种。引入物种向入侵物种的过渡在植物的背景下得到了很好的描述。此外，约有42％endangered speciesare at risk due to an invasive species.

一种入侵物种通过各种方式传播到本地环境 - 偶然地通过人类，木材，运输调色板和板条箱，在世界各地运送，观赏植物，意外释放宠物等。一些知名的入侵物种是入侵的鲤鱼，缅甸python，棕色的臭虫，斑马贻贝等。

What are the Similarities Between an Introduced Species and an Invasive Species?

• Introduced species and invasive species are non-native species.
• 这两种物种都生活在其本地分布范围之外。
• Both species can be spread by humans unintentionally.
• They are both termed as new biota.

引入物种和入侵物种有什么区别？

引入的物种是一种非本地物种，被人类或其他方式引入本地环境，而入侵物种是一种引入物种，它被传播到引言之外，并对附近物种造成损害。因此，这是引入物种和入侵物种之间的关键区别。此外，引入的物种可能会对新的本地环境造成正面或负面影响，而入侵物种总是会对新的本地环境造成负面影响。

Summary – Introduced Species vs Invasive Species

起源于当前位置以外的地方的物种称为非本地物种。引入的物种和入侵物种都是非本地的。引入的物种是一种外来物种，被人类或其他手段引入本地环境，而引入的物种则被引入，该物种散布在引言之外，附近物种损害。因此，这是引入物种和入侵物种之间的关键区别
