In the Anthropocene, alien species are no longer the only category of biological organism establishing and rapidly spreading beyond historical boundaries. We review evidence showing that invasions by native species are a global phenomenon and present case studies from Southern Africa, and elsewhere, that reveal how climate-mediated expansions of native plants into adjacent communities can emulate the functional and structural changes associated with invasions by alien plant species. We conclude that integrating native invasions into ecological practice and theory will improve mechanistic models and better inform policy and adaptive ecological management in the 21st century.
在人类世，外来物种不再是唯一一类在历史边界之外建立和迅速传播的生物有机体。我们回顾了一些证据，这些证据表明，本地物种的入侵是一种全球性现象，并介绍了来自南非和其他地区的案例研究，这些研究揭示了气候如何介导本地植物向相邻群落的扩张，从而模拟与外来植物物种入侵相关的功能和结构变化。我们的结论是，将本地物种的入侵纳入生态实践和理论，将提高机械模型，并在 21 世纪更好地为政策和适应性生态管理提供信息。
