Common eider and herring gull as contaminant indicators of different ecological niches of an urban fjord system
Thorstensen, Helene; Ruus, Anders; Helberg, Morten; Bæk, Kine; Enge, Ellen Katrin; Borgå, Katrine (Peer reviewed; Journal article, 2020)Seabirds like gulls are common indicators in contaminant monitoring. The herring gull (Larus argentatus) is a generalist with a broad range of dietary sources, possibly introducing a weakness in its representativeness of ... -
