Popis | Long-lasting association of European plants with humans in their native range is frequently thought to be behind their success as aliens worldwide. We combined two available databases, the European Vegetation Checklist and the Global Naturalized Alien Flora (GloNAF) to compare human-made, semi-natural and naturalhabitats of Europe as donors of naturalized species to the rest of the globe. We also examined how these habitat categories based on level of human-induced disturbances affect the probability of naturalization of their plant species outside of the native ranges. Our data set contained 9,875 native European vascular plant species assigned to 37 European habitats, 2,550 of these species have become naturalized outside native range. Therefore, our study provides the most comprehensive analysis of the role of native-range habitats on naturalization probability available. Generalized linear models showed that European species with broad habitat range, i.e. those able to occur in human-made and semi-natural or natural habitats at the same time, and species confined to human-made and semi-natural habitats only had a significantly higher probability of becoming naturalized than species of natural habitats. From species linked to human-made habitats or combining the occurrence in them and other habitats, 64.7% ?41.7% have naturalized elsewhere. In contrast, 19.4% of species confined to natural habitats were identified as naturalized. Species associated with arable land and human settlements have naturalized in the largest number of regions (82.5% of all world regions recognized). Our findings highlighted broad habitat range and European plant species’ association with highly or moderately human-disturbed habitats in the native range as factors significantly contributing to the global invasion patterns. |
