Data for: Jiménez-Alfaro et al, Postglacial determinants of regional species pools in alpine grasslands Global Ecology and Biogeography GIS data: shapefiles for total alpine areas, LGM total areas, and current alpine grasslands R_analyses: Scripts for replicating the analyses and the raw data necesary for it -> Estimating regional species pools (INExt estimates and completeness) -> Analysis of richness (SARs and GLMMs) -> Analysis of composition (GDMs and Dispersal Direction) Regions, species and plots: -> Plot information (original ID, database) and contact of data providers, to be connected with the raw data in the R folder -> regional_data: an Excel copy of all data compiled for each region -> species x regions: whole matrix (the same provided as an R file) -> species_data: full species list with information about elevation range and alpine/non-alpine
