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 ... -
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 ... -
Differences in Trophic Level, Contaminant Load, and DNA Damage in an Urban and a Remote Herring Gull (Larus argentatus) Breeding Colony in Coastal Norway
Keilen, Ellen Kristine; Borgå, Katrine; Thorstensen, Helene Skjeie; Hylland, Ketil; Helberg, Morten; Warner, Nicholas Alexander; Bæk, Kine; Reiertsen, Tone Kristin; Ruus, Anders (Peer reviewed; Journal article, 2022)Herring gulls (Larus argentatus) are opportunistic feeders, resulting in contaminant exposure depending on area and habitat. We compared contaminant concentrations and dietary markers between two herring gull breeding ... -

Is Glacial Meltwater a Secondary Source of Legacy Contaminants to Arctic Coastal Food Webs?
Mcgovern, Maeve; Warner, Nicholas Alexander; Borgå, Katrine; Evenset, Anita; Carlsson, Pernilla Marianne; Skogsberg, Stina Linnea Emelie; Søreide, Janne; Ruus, Anders; Christensen, Guttorm; Poste, Amanda (Peer reviewed; Journal article, 2022)Climate change-driven increases in air and sea temperatures are rapidly thawing the Arctic cryosphere with potential for remobilization and accumulation of legacy persistent organic pollutants (POPs) in adjacent coastal ... -
Maternal transfer and occurrence of siloxanes, chlorinated paraffins, metals, PFAS and legacy POPs in herring gulls (Larus argentatus) of different urban influence
Knudtzon, Nina Cathrine; Thorstensen, Helene; Ruus, Anders; Helberg, Morten; Bæk, Kine; Enge, Ellen Katrin; Borgå, Katrine (Peer reviewed; Journal article, 2021)Urban herring gulls (Larus argentatus) are exposed to contaminants from aquatic, terrestrial and anthropogenic sources. We aim to assess if differences in urbanisation affect ecological niche and contaminant concentrations ... -
Methylmercury biomagnification in an Arctic pelagic food web
Ruus, Anders; Øverjordet, Ida Beathe; Braaten, Hans Fredrik Veiteberg; Evenset, Anita; Christensen, Guttorm N.; Heimstad, Eldbjørg Sofie; Gabrielsen, Geir W.; Borgå, Katrine (Peer reviewed; Journal article, 2015)Mercury (Hg) is a toxic element that enters the biosphere from natural and anthropogenic sources, and emitted gaseous Hg enters the Arctic from lower latitudes by long-range transport. In aquatic systems, anoxic conditions ... -
Small Arctic rivers transport legacy contaminants from thawing catchments to coastal areas in Kongsfjorden, Svalbard
Mcgovern, Maeve; Borgå, Katrine; Heimstad, Eldbjørg Sofie; Ruus, Anders; Christensen, Guttorm; Evenset, Anita (Peer reviewed; Journal article, 2022)Decades of atmospheric and oceanic long-range transport from lower latitudes have resulted in deposition and storage of persistent organic pollutants (POPs) in Arctic regions. With increased temperatures, melting glaciers ...
