Isotopic variability in bone collagen of short-tailed albatrosses (Phoebastria albatrus) in the Bering Sea area during the Holocene
Biology Bulletin 51: 791–799
doi: 10.1134/S1062359023606614
The short-tailed albatross (Phoebastria albatrus) is a rare bird species today, numbers of which declined significantly in the Holocene due to human hunting activities. Bones of albatrosses from archaeological sites of Chukotka, Kamchatka, and the Aleutian Islands, and from coastal sediments of the Commander Islands were used to analyze the content of stable carbon and nitrogen isotopes in bone collagen. The analysis showed that the isotopic niches of Aleutian and Commander albatrosses diverged during the Holocene. Short-tailed albatrosses of the Aleutian Islands are closer to Holocene albatrosses of Vancouver Island (Canada) in the isotopic characteristics.
