对与植物入侵性相关的性状的研究产生了相互矛盾的结果，部分原因是大多数以前的研究没有认识到，不同的性状在沿着引进-归化-入侵连续体的不同阶段是重要的。在这里，我们表明，在温带中欧的六个不同的栖息地类型，归化的非入侵物种在功能上类似于本地物种发生在同一栖息地类型，但入侵物种是不同的，因为它们占据了植物功能性状空间的边缘，在每个栖息地。这种模式主要是由入侵物种的平均高度较高所驱动的。这些结果表明，成功建立外来物种在常驻植物群落的主要决定因素是环境过滤，这是表示在相似的性状分布。然而，要成为入侵者，已建立的外来物种需要足够不同，以占据新的生态位空间，即特征空间的边缘。植物功能性状可能有助于区分引入的物种，将成为入侵者，从那些不。在这里，Divíšek等人表明，归化植物物种的功能特征与本地植物相似，而入侵植物物种的功能特征存在于功能特征空间的边缘。
The search for traits associated with plant invasiveness has yielded contradictory results, in part because most previous studies have failed to recognize that different traits are important at different stages along the introduction–naturalization–invasion continuum. Here we show that across six different habitat types in temperate Central Europe, naturalized non-invasive species are functionally similar to native species occurring in the same habitat type, but invasive species are different as they occupy the edge of the plant functional trait space represented in each habitat. This pattern was driven mainly by the greater average height of invasive species. These results suggest that the primary determinant of successful establishment of alien species in resident plant communities is environmental filtering, which is expressed in similar trait distributions. However, to become invasive, established alien species need to be different enough to occupy novel niche space, i.e. the edge of trait space. Plant functional traits may help distinguish introduced species that will become invasive from those that do not. Here, Divíšek et al. show that functional profiles of naturalized plant species are similar to natives, while those of invasive plant species exist at the edge of the functional trait space.
