The climate predictors (i.e. bioclim variables) used for ecological niche modeling are included in the file ''predictors.rar'' The ocurrences used for ecological niche modelling are included in the file ''records.rar'' The climate layers used for the Mid-Holocene and LGM projections are included in the file ''GCMs.rar'' The outputs of each ecological niche model (i.e. ascii files of current predictions and past projections) are compressed in independent rar files (e.g. ''carpathianS1.rar'' for Carpathian lineage model with Set 1 , ''C_glareolusS2.rar'' for the species level model with set 2).
