Ecological Conditions and Health of Arctic Wetlands Modified by Nutrient and Contaminant Inputs from Colonial Birds
The Arctic supports relatively few but large colonies of seabirds. These birds feed in the ocean, often on contaminated food webs, then concentrate and transport nutrients and contaminants through digestion. Back at the colony, the birds release these chemicals, which can then move into terrestrial food webs, accumulating in organisms that would not normally be exposed to these concentrations. Wetlands around Arctic seabird colonies may be oases of life due to nutrient deposition from seabirds, but they also become point sources of certain contaminants.
