Trace elements and stable isotopes in penguin chicks and eggs. A baseline for monitoring the Ross Sea MPA and trophic transfer studies
Multi-tissue trace elements (TEs), C, N concentrations and stable isotopes (δ13C, δ15N) of chick carcasses and eggs of Adélie and Emperor penguins were studied to i) provide reference data before the recent institution of the Ross Sea Marine Protected Area (Antarctica), and ii) provide conversion f...
