Resistance values corresponding to the resistance maps taken evaluated.

Binary landscape resitance maps: 1) Land_A-Land_G: Binary resistance maps, on a gradient from greater to lesser preference of the focal species in relation to forest environment; 2) Land_Ab-Land_Gb: Maps with letter “b” include the barrier effect of national roads, highways, urban areas, reservoirs and quarries. All the models were evaluated for 4 different resistance values (X = 5, 25, 50, 100) (e.g. Land_A5 correspond to Land_A model with resistance value of 5). Ecological Network resistance map: 1) EN: a resistance map analogous to that used in the design of the ecological network of the Basque country; ENnb: a variant of the latter which diminishes the barrier effect of national roads, highways, urban areas, water reservoirs and quarries.Resistance values corresponding to the resistance maps taken evaluated.
