TL;DR: No conclusive evidence that A. macquariensis deaths were caused by a definitive disease-causing pathogen emerged, but the presence of bacterial, fungal and oomycete taxa, some potentially pathogenic, suggested that stressed cushions could become susceptible to infection.

Population trends of Adélie penguin (Pygoscelis adeliae) breeding colonies: a spatial analysis of the effects of snow accumulation and human activities
TL;DR: Whether potential changes in snow cover and/or proximity to human activities were able to explain the varying population trends of colonies at two breeding localities near Casey, East Antarctica is examined.
Population trends of Adélie penguin (Pygoscelis adeliae) breeding colonies: a spatial analysis of the eVects of snow accumulation and human activities
TL;DR: This paper used Geographic Information Systems and decision trees to examine whether potential changes in snow cover and/or proximity to human activities were able to explain the varying population trends of colonies at two breeding localities near Casey, East Antarctica.
