Summary: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 of native range 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. Replanteamiento del Concepto de Distribución Nativa Resumen Una especie es no nativa fuera de su distribución nativa, pero este último concepto no está definido con precisión. La literatura sobre las especies invasoras contiene amplias discusiones sobre los conceptos centrales, como la naturalización, la invasividad y el impacto ecológico, pero el concepto de distribución nativa ha recibido tan poca atención que una definición formal no existe dentro de la literatura. Consideré, entre otros impedimentos para la obtención de una definición formal de distribución nativa, la arbitrariedad ocasional de los límites espaciales y temporales asignados a la distribución nativa. Las preguntas generales que permanecen sin respuesta incluyen si se puede utilizar la teoría de la invasión para definir la distribución nativa para las especies que no cuentan con distribuciones no nativas. 摘要 物种在其原生地之外的地区会被看作是外来种, 但原生地这个概念本身尚没有准确的定义。入侵生物学相关文献对这个问题的核心概念 (如归化、入侵能力和生态影响) 有广泛的讨论, 然而却很少关注原生地的概念, 以至于对其没有正式的定义。本文探讨了对原生地进行正式定义的诸多阻碍中, 用于划定原生地的时间和空间限制的随意性问题。此外仍存在一些宽泛的问题, 如入侵理论能否用于定义没有非原生地的物种的原生地。翻译:胡怡思;审校:聂永刚 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.
