Table 1. BioClim variables used in modelling the bioclimatic niches.
| Variable Code | Variable | 0.9 | 0.8 | 0.7 |
|---|---|---|---|---|
| Bio 1 | Annual Mean Temperature | + | - | - |
| Bio 3 | Isothermality* | + | + | + |
| Bio 4 | Temperature Seasonality (standard deviation *100) | + | + | + |
| Bio 7 | Temperature Annual Range | + | - | - |
| Bio 9 | Mean Temperature of Driest Quarter | + | - | - |
| Bio 12 | Annual Precipitation | + | + | + |
| Bio13 | Precipitation of Wettest Month | + | - | - |
| Bio 15 | Precipitation Seasonality (Coefficient of Variation) | + | + | + |
| Bio18 | Precipitation of Warmest Quarter | + | + | - |
0.7, 0.8, 0.9 refer to threshold of the maximum correlation (Spearman’s rank) between BioClim variables value beyond which the data were considered as independent.
*Isothermality = [Mean Diurnal Range (Mean of monthly (max temp–min temp)) / Temperature Annual Range]
