达尔文的归化假说预测，由于竞争减少，在本土植物区系中没有近亲的情况下，入侵物种应该在它们的新范围内表现得更好。然而，最近的分类学和基于系统发育的研究的证据是模棱两可的。我们使用英国本土和外来植物(约1600种)的化石分子系统发育树和1998年乡村调查的广泛、精细的调查数据，在两个不同的空间尺度上检验了达尔文的归化假说。在景观和局部尺度上，入侵物种与本地植物区系的关联度均不显著高于或低于非入侵外来物种。相反，物种入侵与较高的氮素和水分偏好有关，而与生活型和身高等其他生活史特征无关。因此，我们认为，入侵物种在英国的传播更有可能是由土地利用和其他人为因素的变化决定的，而不是进化历史。综合。从非侵入性到侵袭性的转变与土著社区的系统发育独特性无关，而是与他们的环境偏好有关。因此，在英国和其他工业化国家打击生物入侵需要与在更自然的环境中完全不同的策略。
Darwin's naturalization hypothesis predicts that invasive species should perform better in their novel range in the absence of close relatives in the native flora due to reduced competition. Evidence from recent taxonomic and phylogenetic-based studies, however, is equivocal. We test Darwin's naturalization hypothesis at two different spatial scales using a fossil-dated molecular phylogenetic tree of the British native and alien flora (ca. 1600 species) and extensive, fine-scale survey data from the 1998 Countryside Survey. At both landscape and local scales, invasive species were neither significantly more nor less related to the native flora than their non-invasive alien counterparts. Species invasiveness was instead correlated with higher nitrogen and moisture preference, but not other life history traits such as life-form and height. We argue that invasive species spread in Britain is hence more likely determined by changes in land use and other anthropogenic factors, rather than evolutionary history. Synthesis. The transition from non-invasive to invasive is not related to phylogenetic distinctiveness to the native community, but instead to their environmental preferences. Therefore, combating biological invasions in the Britain and other industrialized countries need entirely different strategies than in more natural environments.
