FIG 2.
Jackknife results for the best model predicting the suitability of habitats for Ixodes ricinus. The variables Dim1 to Dim26 correspond to the components of the PCA needed to retain 95% of the variance. AUCtotal corresponds to the performance of the model with all environmental variables, AUConly the performance with only the environmental variable mentioned in the first column, and AUCwithout being the performance with all the variables except the one mentioned. The column with +/− indicates the type of association between the component and the presence of Ixodes ricinus (with a positive association, the higher the value of the PCA dimension, the higher the suitability for ticks). The last column shows the raw environmental variable most correlated with the PCA dimension, with the value of the correlation indicated in parentheses (Temp, temperature; RH, relative humidity; Quant, quantile; Prec, precipitation; Perc, percentage).
