Adélie penguins colonization history and paleodiet trends document Holocene environmental changes in Victoria Land (Antarctica)
The identification of several abandoned penguin colonies on Victoria Land coastal areas and more than 200 radiocarbon dates provide a ≈7200-yr spanning Adélie penguin history (> 8000 yr BP considering calibrated dates). These data also supply information about Holocene environmental changes, esp...
