ψA = occupancy of dominant species; ψBA = occupancy of subordinate species when the dominant species is present; ψBa = occupancy of subordinate species when the dominant species is absent. Reserve dist = Covariate ‘weighted distance to reserve border’. We used “=” to designate that two or more parameters were set as equal (e.g., ψBA = ψBa means that the occupancy of the subordinate species is independent of that of the dominant species). We used “≠” to designate that two or more parameters were set as different (e.g., ψBA≠ψBa models assumed that the occupancy of the subordinate species was influenced by the dominant species).
