The cost and benefits of territorial tenure, and factors affecting mating success in male Antarctic fur seals
The timing, location and duration of territorial tenure, and the mating success and return rates of male Antarctic fur seals (Arctocephalus gazella) were measured over four consecutive breeding seasons (1984–87) on Bird Island (54°00’S, 38°02’W), South Georgia. Tenure duration (days) followed a heavily skewed, Poisson-like distribution (median 13.08 days, maximum 75 days) and was positively related to the number of years of tenure (rs= 0.52, P 0.7) or to the level of mating success in the current year (P > 0.15). It was, however, positively related to the duration of tenure in the current year (P < 0.0001). The overall annual return rate was 43% which is not significantly different from the survival rate for the general male population and suggests that territorial tenure does not contribute to increased mortality in male Antarctic fur seals.
