Alien mammals

The data file contains data on the status of alien (non-native) mammalian species at the global scale from introduction to spread, number of unique introduction locations for all introduced species, and mean life history traits for all species. The README file provides the basic details on the variables in the datafile. Full details on the protocol for the extraction of the data from the literature, classification of the species, and references underling the data can be found in the Supplementary Information file of the Ecology Letters paper (for details on the data collection: SI, Section 1.1; for additional data references: SI, 4.2)
