Dynamics of Antarctic penguin populations in relation to inter-annual variability in sea-ice distribution
Abstract: To investigate the role of sea ice cover on penguin populations we used principal ... component analysis to compare population variables of Adélie (Pygoscelis adeliae) and chinstrap (Pygoscelis ... population size remained stable, whereas that of chinstrap penguins decreased slightly. For neither species ... apparent inverse density-dependent relationship between the number of Adélie breeding pairs and the number ...
