註釋The Great Lakes of North America are one of the most heavily contaminated freshwater ecosystems in the world, yet they support at least one-third of North America's breeding Caspian tern population. To assess the health of this breeding population in relation to organochlorine contaminant (OC) levels, a study was conducted of 10 colonies (6,800 nests) throughout its Great Lakes range in 1991. The study considered residues in relation to reproductive output, diet, and population trends at individual colonies and examined the suitability of this species as a sensitive indicator of the toxic effects of anthropogenic chemicals.
