Correlation circles of the principal component analysis included the 10 environmental variables describing each study site (Suit.area and all variables described in Additional file 4) and a the adult badger density (DAd) with the seven variables used in Eq. 1 or b the badger density (DBad) with the seven variables used in Eq. 2. The sum of the eigenvalues for the first three axes of the PCAs accounted for a 66% and b 69% of the total variability
