Due to anthropogenic pressure some species have declined whereas others have increased within their native ranges. Simultaneously, many species introduced by humans have established self-sustaining populations elsewhere (i.e. have become naturalized aliens). Previous studies have shown that particularly plant species that are common within their native range have become naturalized elsewhere. However, how changes in native distributions correlate with naturalization elsewhere is unknown. We compare data on grid-cell occupancy of native vascular plant species over time for 10 European regions (countries or parts thereof). For nine regions, both early occupancy and occupancy change correlate positively with global naturalization success (quantified as naturalization in any administrative region and as the number of such regions). In other words, many plant species spreading globally as naturalized aliens are also expanding within their native regions. This implies that integrating data on native occupancy dynamics in invasion risk assessments might help prevent new invasions.
由于人为压力，一些物种数量在其原生范围内有所减少，而另一些物种数量则有所增加。与此同时，许多由人类引入的物种在其他地方建立了自我维持的种群（即已成为归化外来物种）。先前的研究表明，特别是在其原生范围内常见的植物物种已在其他地方归化。然而，原生分布的变化与在其他地方的归化之间如何关联尚不清楚。我们比较了10个欧洲地区（国家或其部分地区）本土维管植物物种随时间的网格单元占用数据。对于九个地区，早期占用率和占用率变化均与全球归化成功率呈正相关（量化为在任何行政区的归化情况以及此类行政区的数量）。换句话说，许多作为归化外来物种在全球扩散的植物物种也在其原生地区内扩张。这意味着在入侵风险评估中整合有关本土占用动态的数据可能有助于防止新的入侵。
