2.6 Resistance surface for connectivity analysis
To estimate landscape resistance, we converted the habitat suitability maps to resistance maps using a negative exponential function using this equation:
R= 1000^(-1×HS)
Where R represents the cost resistance value assigned to each pixel and HS represents the predicted habitat suitability derived from the suitability models described above (Mateo-Sánchez et al., 2015; Wan, Cushman, & Ganey, 2019). We rescaled the resistance values to a range between 1 and 10 by linear interpolation, such that minimum resistance (Rmin) was 1 when HS was 1, and maximum resistance (Rmax) was 10 when HS was 0 (Wan et al., 2019).
