A species is not native outside its native range, but native range is not precisely defined. The invasion literature contains wide discussion of the core concepts, such as naturalization, invasiveness, and ecological impact, but the concept has received so little attention that a formal definition does not exist. I considered, among other impediments to a formal definition of native range, the sometimes arbitrariness of the spatial and temporal limits assigned to native range. Broad questions that remain include whether invasion theory can be used to define the native range for species without non-native ranges. Article impact statement: A precise definition of native range is needed to properly define native species and thus apply the origin of species in conservation.

重新思考原生范围概念

一个物种在其原生范围之外不是原生的，但原生范围并没有精确定义。入侵文献包含对归化、入侵和生态影响等核心概念的广泛讨论，但该概念很少受到关注，以至于不存在正式定义。我考虑过，除了对原生范围进行正式定义的其他障碍之外，分配给原生范围的空间和时间限制有时是任意的。仍然存在的广泛问题包括入侵理论是否可用于定义没有非本地范围的物种的本地范围。文章影响声明：需要准确定义本地范围以正确定义本地物种，从而将物种起源应用于保护。本文受版权保护。版权所有。
