Environmental predictors used to derive species distribution models.

*AspNS  =  sine (radiant [aspect angle in degree]); †AspEW  =  cosine (radiant [aspect angle in degree]); ‡Isothermality %  =  Mean Diurnal Range (MDR)/Temperature Annual Range (TAR); where MDR  =  Mean of monthly (max temp – min temp)); TAR  =  Max Temperature of Warmest Month – Min Temperature of Coldest Month. Isothermality is a quantification of how large the day-to-night temperature oscillation is in comparison to the summer-to-winter oscillation. A value of 100 would represent a site where the diurnal temperature range is equal to the annual temperature range. A value of 50 would indicate a location where the diurnal temperature range is half of the annual temperature range.
