Contaminants, ecotoxicology and climate change: interactions in Arctic seabirds at their southern range limits
Impacts of NCP-priority chemicals on endocrine function, energetics, and behavior, in conjunction with changing ice conditions, will be examined in thick-billed murres (Coats Island) where climate change is impacting their health. When ice breaks up earlier, energetics of adult murres is increased, they obtain less food, and nestling growth is slowed. Endocrine changes from e.g., chemical exposure, may decouple relationships between corticosterone, thyroid hormones, energy expenditure, and behavior. Specifically, because high energy expenditure is necessary to access food when ice is far away versus when ice is near, chemical disruption of these relationships may explain the inappropriate foraging behavior responses of some birds to changing ice conditions.
