Fischer, Markus Dawson, Wayne deposit-license 2011 The maximum relative growth rate of common UK plant species is positively associated with their global invasiveness Aim: An emerging consensus in invasion ecology is that faster-growing alien plant<br />species tend to be more invasive than slower-growing species. However, phylogenetic<br />non-independence and the precision of growth-rate measures often remain<br />unaccounted for in comparative studies.We tested whether global invasiveness was<br />related to mean and maximum relative growth rate of 105 plant species (101 native<br />and 4 introduced) commonly occurring in the UK.<br />Location: Global.<br />Methods: We combined a unique experimental dataset of relative growth rates<br />(RGR) measured under standardized experimental conditions for plant species that<br />occur widely in the UK with our global measures of invasiveness, which were the<br />number of references in the Global Compendium of Weeds (GCW) and the<br />number of world regions invaded.We weighted mean RGR measures per species by<br />including variances of RGR in our analyses, and we also conducted analyses with<br />and without phylogenetic structure, to account for potential phylogenetic nonindependence<br />in RGR.<br />Results: We found a positive association between global invasiveness and<br />maximum RGR. In addition, this association was not confounded by phylogenetic<br />correlation, or by species seed mass.<br />Main conclusions: The results from this study suggest that faster-growing species<br />are more widespread at a global scale, adding support to other studies that suggest<br />faster-growing alien plant species tend to be more invasive in the introduced range. van Kleunen, Mark Fischer, Markus eng 2011-06-27T14:20:43Z 2012-05-31T22:25:04Z van Kleunen, Mark First publ. in: Global Ecology and Biogeography, 20 (2011), 2, pp. 299–306 Dawson, Wayne
