Anthropogenic flank attack on polar bears: interacting consequences of climate warming and pollutant exposure
Jenssen, Bjørn Munro; Villanger, Gro Dehli; Gabrielsen, Kristin Møller; Bytingsvik, Jenny; Bechshoft, Thea; Ciesielski, Tomasz Maciej; Sonne, Christian; Dietz, Rune (Journal article; Peer reviewed, 2015)Polar bears (Ursus maritimus) are subjected to several anthropogenic threats, climate warming and exposure to pollutants being two of these. For polar bears, one of the main effects of climate warming is limited access to ... -

DNA Double-Strand Breaks in Arctic Char, Salvelinus alpinus, from Bjørnøya
Neerland, Eirik Degnes (Master thesis, 2016)Long-range atmospheric transport has led to persistent organic pollutants (POPs) finding their way far from their sources of origin and into the Arctic and are accumulated in biota. The activity of large seabird colonies ... -
DNA double‐strand breaks in Arctic char (Salvelinus alpinus) from Bjørnøya in the Norwegian Arctic
Neerland, Eirik D.; Bytingsvik, Jenny; Nikiforov, Vladimir; Evenset, Anita; Krøkje, Åse (Journal article; Peer reviewed, 2019)High levels of organochlorine contaminants (OCs) have been found in arctic char (Salvelinus alpinus) from Lake Ellasjøen, Bjørnøya (Norwegian Arctic). The aim of the present study was to investigate the potential genotoxic ... -
Effects of biometrics, location and persistent organic pollutants on blood clinical-chemical parameters in polar bears (Ursus maritimus) from Svalbard, Norway
Ciesielski, Tomasz Maciej; Sonne, Christian; Ormbostad, Ingunn; Aars, Jon; Lie, Elisabeth; Bytingsvik, Jenny; Jenssen, Bjørn Munro (Journal article; Peer reviewed, 2018)In the present study, blood clinical-chemical parameters (BCCPs) were analysed in 20 female and 18 male Svalbard polar bears (Ursus maritimus) captured in spring 2007. The aim was to study how age, body condition (BC), ... -
Expression of DNA repair genes in arctic char (Salvelinus alpinus) from Bjørnøya in the Norwegian Arctic
Inderberg, Helene; Neerland, Eirik D.; Mcpartland, Molly; Sparstad, Torfinn; Bytingsvik, Jenny; Nikiforov, Vladimir A; Evenset, Anita; Krøkje, Åse (Peer reviewed; Journal article, 2021)High levels of organochlorines (OCs) have been measured in arctic char (Salvelinus alpinus) from Lake Ellasjøen on Bjørnøya, Norway (74.30°N, 19.0°E). In a nearby lake, Laksvatn, the OC-levels in arctic char were low. A ... -
Organohalogenated contaminants (OHCs) in polar bear mother-cub pairs from Svalbard, Norway: Maternal transfer, exposure assessment and thyroid hormone disruptive effects in polar bear cubs
Bytingsvik, Jenny (Doktoravhandlinger ved NTNU, 1503-8181; 2012:259, Doctoral thesis, 2012)As the top predator of the arctic marine food chain, polar bears (Ursus maritimus) accumulate high levels of organohalogenated compounds (OHCs) such as polychlorinated biphenyls (PCBs), brominated flame retardants (BFRs), ... -
Relationships between POPs, biometrics and circulating steroids in male polar bears (Ursus maritimus) from Svalbard
Ciesielski, Tomasz Maciej; Hansen, Ingunn Tjelta; Bytingsvik, Jenny; Hansen, Martin; Lie, Elisabeth; Aars, Jon; Jenssen, Bjørn Munro; Styrishave, Bjarne (Journal article; Peer reviewed, 2017)The aim of this study was to determine the effects of persistent organic pollutants (POPs) and biometric variables on circulating levels of steroid hormones (androgens, estrogens and progestagens) in male polar bears (Ursus ... -
Temporal Change and Effects of Perfluoroalkyl Substanses (PFASs) on Thyroid Hormone Levels in Mother-Cub Pairs of Polar Bear (Ursus maritimus) from Svalbard in 1998 and 2008
Nilsen, Else Mari Espseth (Master thesis, 2011)High levels of persistent organic pollutants (POPs) have been detected in the Arctic wildlife. While many of the traditional POPs have been reported to decline the last decades, emerging contaminants such as perfluoroalkyl ... -
