Holocene Adélie penguin diet in Victoria Land, Antarctica
Ornithogenic soils (N = 97) dated up to 7000 Before Present (BP) were sampled in 16 relict and modern breeding colonies of Adélie penguin along the Victoria Land coast (Ross Sea, Antarctica). Taxonomic identification of fish otoliths (N = 677) recovered in these soils allowed to identify the Antarc...
