Data from : Historical legacies and ecological determinants of grass naturalizations worldwide

The global distribution of exotic species is the result of abiotic, biotic and dispersal
filtering processes that shape the movement and success of species outside their native
range. In this study we aim to understand how these filtering processes drive the fluxes
of grass species among regions, the factors that influence which species establish outside
of their native range, and where they do so.

We used national and subnational checklists of native and introduced grass species
to determine the extent to which each region was a source or recipient of exotic grass
species. We asked how species traits may distinguish those grass species that have naturalized
outside their native range from those that have not, and how environmental
conditions are related to the distribution of exotic grass species.

We found that exotic grass establishment is shaped by an array of factors including
characteristics of regions, traits of species and their interactions. Regions with a lon...
