Topographic and bioclimatic variables ranked according to their overall model contribution for continental species of the genus Epicrates.

AUC is the area under the curve in ROC plots. Bioclimatic variables are as follows: AMT, Annual mean temperature; MMTR, Mean monthly temperature range; I, Isothermality; TS, Temperature seasonality; MaxTWM, Max. temperature warmest month, MinTCM, Min. temperature coldest month, AP, Annual precipitation, PWM, Precipitation wettest month; PDM, Precipitation driest month; PS, Precipitation seasonality; PWQ, Precipitation warmest quarter; PCQ, Precipitation coldest quarter.
