Phylogenetic structure of alien plant species pools from European donor habitats

Aim Many plant species native to Europe have naturalized worldwide. We tested whether the phylogenetic structure of pools European habitats is related proportion from each habitat that has outside (habitat’s donor role) and donated are more phylogenetically other than expected by chance. Location (native range), rest world (invaded range). Time period Last c. 100 years. Major taxa studied Angiospermae. Methods selected 33 in analysed their pools, including 9,636 species, which 2,293 Europe. assessed as difference between observed mean pairwise distance (MPD) for (a) whole pool (b) subgroups those not. used generalized linear models test effects level human influence on habitat’s role. Results Habitats strongly moderately influenced humans often showed clustered pools. Within a random structure. Species less human-influenced natural varied overdispersed, with also showing patterns within Donor roles both groups increased increasing MPD habitats. Main conclusions donate closely naturalize disturbed range. Natural different lineages various ecological strategies allow them succeed invaded However, most subsets
