Variables selected for ENFA predictor sets.

The ENFA derived parameters are determined separately for each of the species boundary hypotheses and for all four species combined. The scores calculated across the Köppen-Geiger background are on the left and the GEnS scores on the right. The total marginality score will increase above 1 when considering all predictor variable marginality scores. Bio02 =  Mean diurnal temperature range (mean(period max-min)) (°C); Bio03 =  Isothermality (Bio02 ÷ Bio07); Bio04 =  Temperature seasonality (C of V); Bio06 =  Min temperature of coldest week (°C); Bio07 =  Temperature annual range (Max temperature of warmest week - Bio06) (°C); Bio11 =  Mean temperature of coldest quarter (°C); Bio12 =  Annual precipitation (mm); Bio14 =  Precipitation of driest week (mm); Bio17 =  Precipitation of driest quarter (mm); Bio18 =  Precipitation of warmest quarter (mm); Bio21 =  Highest weekly radiation (W m−2); Bio26 =  Radiation of warmest quarter (W m−2); Bio27 =  Radiation of coldest quarter (W m−2); Bio28 =  Annual mean moisture index; Bio29 =  Highest weekly moisture index; Bio30 =  Lowest weekly moisture index; Bio32 =  Mean moisture index of wettest quarter; Bio33 =  Mean moisture index of driest quarter; Bio34 =  Mean moisture index of warmest quarter; Bio35 =  Mean moisture index of coldest quarter.
