Oxidative stress in relation to reproduction, contaminants, gender and age in a long-lived seabird
Abstract: Reproduction is a demanding activity for animals, since they must produce, and in some cases protect and provision, their young. It is often overlooked that demands of reproduction may also be exacerbated by exposure to contaminants. In this study, we make use of an exceptional long-term d...
