Population trends of Adélie penguin (Pygoscelis adeliae) breeding colonies: a spatial analysis of the effects of snow accumulation and human activities
Abstract Many of the Adélie penguin colonies used for long-term demographic studies are located near research stations, and there is a need to disentangle the effects of human activities and environmental variability on Adélie penguin population trends. This study used Geographic Information Systems...
