Native and alien species ranges

The file contains native and alien ranges of 1380 species worldwide obtained from the Global Invasive Species Database (http://www.iucngisd.org/gisd/) and CABI Invasive Species Compendium (http://www.cabi.org/isc/). The data are used to produce the results shown in Seebens, Essl & Blasius: The intermediate distance hypothesis of biological invasions, which is accepted for publication in Ecology Letters. The file is in csv format containing six columns: Species name, life form, native range, alien range, distance (great circle distance between the centroids of the respective regions) and species weights. More details about the data and the analysis can be found in Seebens et al.
