Ca, class area (number of pixels (500 m × 500 m) of suitable habitat in the 0.2° pixels where the landscape friction prediction is done; Cnbpmed and Cnbphi, medium and high categories of patch density, respectively [i.e., the number of pixels (500 m × 500 m) of suitable habitat within the 0.2° pixels where the landscape friction prediction is done]; Interflu1, presence of an interfluve; Lpd, logarithm of the maximal distance between patches of suitable habitat; Nbdist, distance along the least-cost paths; Time, time interval between sampling dates. Interactions are denoted with a colon.
