Changing bird migration patterns have potential to enhance dispersal of alien plants from urban centres

Data from: Latitudinal patterns of alien plant invasions
<p>Latitudinal patterns of biodiversity have long been a central topic in ecology and evolutionary biology. However, while most previous studies have focused on native species, little effort has been devoted to latitudinal patterns of plant invasions (with a few exceptions based on data from sparse locations). Using the most up-to-date worldwide native and alien plant distribution data from 801 regions (including islands), we compared invasion levels (i.e. alien richness/total richness) in the Northern and Southern Hemispheres and across continental regions and islands around the globe. Results from quantile regressions using B-splines to model nonlinearity showed (1) declining richness with increasing latitude, although the highest alien richness occurs at around 40 degrees in both hemispheres, (2) decreasing invasion levels towards higher latitudes on islands but a unimodal pattern in invasion level in continental regions in each hemisphere, (3) significantly higher invasion levels on islands than in continental regions, and (4) a greater variability in invasThrough field observations and published records (e.g., literature search).ion levels on islands at low latitudes than on high-latitude islands. In continental regions, only the mid-latitudes had high variability with both low and high invasion levels. Our findings identified latitudes with invasion hotspots where management is urgently needed, and latitudes with many areas of low<b> </b>invasions but high conservation potential where prevention of future invasions should be the priority.</p>
Data set from: Phylogenetic structure of alien plant species pools from European donor habitats
<p><strong>Aim.</strong> Many plant species native to Europe have naturalized worldwide. We tested whether the phylogenetic structure of the species pools of European habitats is related to the proportion of species from each habitat that have naturalized outside Europe (habitat's donor role) and whether the donated species are more phylogenetically related to each other than expected by chance.</p> <p><strong>Location. </strong>Europe (native range), the rest of the World (invaded range).</p> <p><strong>Time period.</strong> Last c. 100 years.</p> <p><strong>Major taxa studied. </strong>Angiospermae.</p> <p><strong>Methods. </strong>We selected<strong> </strong>33 habitats in Europe and analyzed their species pools, including 9,636 plant species, of which 2,293 have naturalized outside Europe. We assessed the phylogenetic structure of each habitat as the difference between the observed and expected mean pairwise phylogenetic distance (MPD) for (a) the whole species pool and (b) subgroups of species that have naturalized outside Europe and those that have not. We used generalized linear models to test for the effects of the phylogenetic structure and the level of human influence on the habitats' donor role.</p> <p><strong>Results. </strong>Habitats strongly to moderately influenced by humans often showed phylogenetically clustered species pools. Within the clustered species pools, those species that have naturalized outside Europe showed a random phylogenetic structure. Species pools of less human-influenced natural habitats varied from phylogenetically clustered to overdispersed, with donated naturalized species also often showing random patterns within the species pools. Donor roles in both habitat groups increased with increasing MPD within habitats.</p> <p><strong>Main conclusions. </strong>European h<span>uman-influenced habitats donate closely related species that </span>often naturalize in disturbed habitats outside their native range. <span>Natural habitats donate species from different lineages with various ecological strategies that allow them to succeed in different habitats in the invaded range</span>. However, in most cases, the naturalized species donated are phylogenetically random subsets of the donor habitats' species pools.</p> <p><strong>Aim.</strong> Many plant species native to Europe have naturalized worldwide.
