Figure 4. Pairwise correlation between the most relevant variables for the fossoriality after excluding the collinear variables. Numbers represent correlation coefficients and ellipses represent the strength and direction of the correlation. Strong correlations are indicated by flat ellipses, whereas weak correlations are indicated by rounded ellipses, as shown in the scale bar. Temp: mean temperature; TempS: temperature seasonality; Prec: annual precipitation; PrecS: precipitation seasonality; Shrub: shrub-covered; Clay3: clay content (15–30cm); Silt1: silt content (0–5cm).
