  • Figure 2. Thermal niche of Archaeolacerta bedriagae at the species range scale. Synthesis of the thermal niche through PCA of eleven bioclimatic variables based on temperature data (A) and detail of the niche described by two specific thermal variables (Max Temperature of Warmest Month – Bio 5 and Mean Temperature of Warmest Quarter – Bio 10) (B). PC1 is mostly associated with Temperature Seasonality (0.99) and PC2 to Isothermality (−0.44), Max Temperature of Warmest Month (−0.39), and Mean Temperature of Wettest Quarter (−0.37). In both plots, grey dots represent thermic availability in the study area, blue dots represent thermic conditions in all the known sites of A. bedriagae presence, and red dots represent thermic conditions in the population sampling sites. Polygons on the axes represent the frequency distribution of the values of thermic availability in the study area (grey polygons) and the frequency distribution of temperature variable values at the presence sites (blue polygons). On the top left of each plot are reported the results of the GLMs comparing climatic conditions at available and occupied sites on the X and Y axes.
