Spurenelementanreicherung in arktischen und borealen Meeresvögeln
Age-related, geographical and interspecific differences in metal accumulations were investigated in three seabird species. Samples were collected in Runde and Hornoya/ Norway, Brittany, German Bight. In beached or starving Common Guillemots negative correlations were found only between Zn, Cu and Se...
