stable isotopes reveal holocene changes in the diet of adélie penguins in northern victoria land (ross sea, antarctica).adélie penguin (pygoscelis adeliae) modern and fossil eggshells and guano samples collected from ornithogenic soils in terra nova bay (victoria land, ross sea) were processed for carbon and nitrogen isotopic ratios with the aim of detecting past penguin dietary changes. a detailed and greatly expanded adélie penguin dietary record dated back to 7,200 years bp has been reconstructed for the investigated area. our data indicate a significant dietary shift between fish and krill, with a gradual dec ...201020886238
