Table 6 Linear models for relative body mass gain (a: 95% home range and sex; b: core area and sex) of grey seals, Sable Island, Nova Scotia, 2009–2011 and 2013–2015

  1. 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). Nseal = 59. Variables for model selection are Akaike’s information criteria (AICc, ΔAICc), Akaike weights (w) and log likelihood (LL)
