The distinction between native and alien species is a main tenet of various natural sciences, invasion biology in particular. However, it is also a contested one, as it does not reflect the biological features of a species, but only its place of origin and migration history. The present paper offers a brief genealogy of the native/alien divide and argues that central to this binary is a national thinking that divides the world into distinct (national) units, enclosed by (natural) borders, with a unique (native) population attached to these spatial units. The paper illustrates this argument by looking at two interrelated processes: the nationalisation of nature, by which the national thinking intervenes as an organising principle in determining ecological inclusion/exclusion, and the naturalisation of the nation, through which the nation is given an ontological status. Taken together these two processes confirm the continuing salience of the nation as a b-ordering principle actively constituting both the social and natural world, also in times of anthropogenic changes and increasing people’s mobility.

当地人和外星人：谁和什么属于自然和国家？

本地物种和外来物种之间的区别是各种自然科学，特别是入侵生物学的主要原则。然而，它也是一个有争议的，因为它不反映一个物种的生物学特征，而只反映它的起源地和迁徙历史。本文提供了本地/外来鸿沟的简要谱系，并认为这种二元化的核心是一种民族思维，将世界划分为不同的（民族）单位，由（自然）边界包围，并附有独特的（本地）人口到这些空间单位。这篇论文通过考察两个相互关联的过程来说明这一论点：自然的国有化，国家思维通过该过程作为确定生态包容/排斥的组织原则进行干预，以及国家的自然化，通过它，民族被赋予了本体论地位。综合这两个过程，确认国家作为积极构成社会和自然世界的 b-ordering 原则的持续显着性，也在人为变化和人们流动性增加的时代。
