外来物种的成功是否可以用它们的功能或系统发育特征来解释仍然没有解决，因为数据有限，规模问题和成功的量化不足。使用永久性草原在法国（50,000植被地块，2000种，130外国人）和Rabinowitz的分类量化传播的基础上，我们表明，系统发育和功能相似性本地人入侵成功的最重要的相关性相比，内在的功能特征和引进历史。结果对比空间尺度和入侵成功的组成部分。广泛和常见的外国人在粗尺度上（表明环境过滤）类似于共同发生的本地人，但在更细的尺度上（表明本地竞争）不同。相比之下，在区域广泛分布，但当地罕见的外国人表现出竞争性排斥模式已经在粗糙的规模。量化外星人和本地人之间的性状差异，区分入侵成功的组成部分，提高了我们在多个尺度上理解和预测外星人传播的能力。
Whether the success of alien species can be explained by their functional or phylogenetic characteristics remains unresolved because of data limitations, scale issues and weak quantifications of success. Using permanent grasslands across France (50,000 vegetation-plots, 2000 species, 130 aliens) and building on the Rabinowitz’ classification to quantify spread, we showed that phylogenetic and functional similarities to natives were the most important correlates of invasion success compared to intrinsic functional characteristics and introduction history. Results contrasted between spatial scales and components of invasion success. Widespread and common aliens were similar to co-occurring natives at coarse scales (indicating environmental filtering), but dissimilar at finer scales (indicating local competition). In contrast, regionally widespread but locally rare aliens showed patterns of competitive exclusion already at coarse scale. Quantifying trait differences between aliens and natives and distinguishing the components of invasion success improved our ability to understand and potentially predict alien spread at multiple scales.
