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.
