In Antarctica, prey availability for the mesopredator Adélie penguin, Pygoscelis adeliae , depends on sea-ice dynamics. By affecting cycles of sea-ice formation and melt, climate change could thus affect penguin diet and recruitment. In the light of climate change, this raises concerns about the fat...
