Territoriality in adult male sub-Antarctic fur seals at Gough Island

Adult male sub-Antarctic fur seals at Gough Island hold territories averaging 21.9 m² during the peak breeding season, with tenure lasting approximately 45 days. Territory size varies significantly by beach type, ranging from 13.8 to 28.3 m². The study analyzed unpublished data from the 1975/76 austral summer and found that both territory tenure and size align with established patterns in fur seal species where males defend land-based territories as a primary reproductive strategy. However, the research also underscores multiple confounding factors that complicate comparative studies on territorial behavior in otariids, emphasizing the need for careful consideration when interpreting theoretical or modeling approaches in this area.
