Oldenbourg: De Gruyter. Data sources are provided in the chapter. With the exception of runoff, environmental variables are rasters created using the focal statistics tool to sum the number of cells within a radius around each cell. They are named according to the following convention: f{radius}_{factor abbreviation}_{variable}.tif Factor abbreviations: A Aspect D DEV geomorphological land form H Hydrology S Slope T TPI geomorphological land form Of these environmental variables, the following were used as background variables in the MaxEnt models: ASKP-LA WHS f500_H_prec_soak f500_H_Runoff f500_T_Valley f5k_D_Ridge f5k_T_Ridge f5k_H_Runoff f5k_H_Runoff f500_D_UpperSlope_or_low_rise f5k_A_Northeast f5k_A_Southwest f500_D_UpperSlope_or_low_rise f500_D_Valley f5k_H_springs f5k_D_Ridge f5k_A_South f5k_A_Southwest f5k_A_Northwest f500_T_UpperSlope_or_low_rise f500_D_Lower_slope_or_shallow_valley f5k_A_North
