Fixed effects of each candidate model are a) 95% home-range area (Hr) and sex (Sx); b) core area (Ca) defined as the 30% isopleth based on number of visits to a hull, and sex (Sx). N_seal = 59. Variables for model selection are Akaike’s information criteria (AICc, ΔAIC_c), Akaike weights (w) and log likelihood (LL)
