Only the best-performing models were selected, and their predictions averaged in an ensemble model weighted by TSS. 7- Future projections produced under climate change scenarios. 8- Binary presence–absence maps generated by applying a 0.5 probability threshold to define presence. 9- Differences between present and future predictions used to identify climate refugia (areas remaining suitable for the species in the future), habitat losses and gains. 10- Model disagreement among individual models included in the ensemble = standard deviation of predictions. 11- Environmental extrapolation assessed with the ExDet tool, based on Mahalanobis distance between calibration and projection spaces: - Univariate extrapolation: values outside the calibration range for at least one predictor. - Combinatorial extrapolation: novel combinations of known predictor values. - Analogous conditions: environments within the calibration space.
