Influence of the Increasing Fur Seal Population on Wandering Albatrosses Diomedea exulans Breeding on Bird Island, South Georgia

摘要: Since 1961, the wandering albatross breeding population at Bird Island, South Georgia has decreased by 22% (1% per annum). 1960 Antarctic fur seals have increased 17% annum; Island was main focus of this increase. The destroyed large areas tussock grassland (the albatrosses habitat) and frequent interactions with are observed. We investigated potential adverse effect on comparing numbers, success other aspects dynamics in different abundances (including absence) seals. Albatross numbers more rapidly most In contrast, over last decade is highest There no evidence that any established but juvenile recruits to tend avoid abundant Because young birds lower reproductive than older birds, movement may create increase average (older) remaining numerous
