Socially-induced variation in physiological mediators of parental care in a colonial bird.
International audience Social facilitation of reproduction occurs in humans and animals, and may represent one of the bases of reproductionin groups. However, its underlying physiological mechanisms remain largely unexplored. Here, we found ina colonial bird, the Adélie penguin (Pygoscelis adeliae),...
