DNA double-strand breaks in relation to persistent organic pollutants in a fasting seabird
Fenstad, Anette; Jenssen, Bjørn Munro; Moe, Børge; Hanssen, Sveinn Are; Bingham, Christopher George; Herzke, Dorte; Bustnes, Jan Ove; Krøkje, Åse (Journal article; Peer reviewed, 2014)Lipophilic persistent organic pollutants (POPs) are released from fat reserves during fasting, causing increased blood concentrations. Thus, POPs represent a potential anthropogenic stressor during fasting periods. We ... -
Endocrine and Fitness Correlates of Long-Chain Perfluorinated Carboxylates Exposure in Arctic Breeding Black-Legged Kittiwakes
Tartu, Sabrina; Gabrielsen, Geir W.; Blévin, Pierre; Ellis, Hugh; Bustnes, Jan Ove; Herzke, Dorte; Chastel, Olivier (Journal article; Peer reviewed, 2014)Increasing levels of poly- and perfluorinated alkyl substances (PFASs) have recently been described in Arctic biota. These emerging substances are of concern given their resistance to degradation and metabolization. Some ... -

Polychlorinated ... -
Integument colouration in relation to persistent organic pollutants and body condition in arctic breeding black-legged kittiwakes (Rissa tridactyla)
Blévin, Pierre; Tartu, Sabrina; Angelier, Frédéric; Leclaire, Sarah; Bustnes, Jan Ove; Moe, Børge; Herzke, Dorte; Gabrielsen, Geir W.; Chastel, Olivier (Journal article; Peer reviewed, 2014)Vertebrates cannot synthetize carotenoids de novo but have to acquire themthrough their diet. In birds, carotenoids are responsible for the yellow to red colouration of many secondary sexual traits. They are also involved ... -
Miljøgifter i rovfuglegg i Norge. Utvikling over tid, og nye giftstoffer
Nygård, Torgeir; Herzke, Dorte; Polder, Anuschka (NINA Rapport;213, Research report, 2006)Nygård, T., Herzke, D. og Polder, A. 2006. Miljøgifter i rovfuglegg i Norge.

Brood patch provides efficient heat transfer between the incubating parent and the developing ... -
Perfluorinated substances and telomeres in an Arctic seabird: Cross-sectional and longitudinal approaches
Blévin, Pierre; Angelier, Frédéric; Tartu, Sabrina; Bustamante, Paco; Herzke, Dorte; Moe, Børge; Bech, Claus; Gabrielsen, Geir Wing; Bustnes, Jan Ove; Chastel, Olivier (Journal article; Peer reviewed, 2017)Telomeres are non-coding DNA repeats located at the termini of eukaryotic chromosomes, regulated by dynamic processes balancing shortening and maintenance. Despite a mechanism to slow-down telomere shortening, cell division ... -
Polychlorinated biphenyl exposure and corticosterone levels in seven polar seabird species
Tartu, S.; Angelier, F.; Bustnes, Jan Ove; Moe, Børge; Hanssen, Sveinn Are; Herzke, Dorte; Gabrielsen, Geir W.; Verboven, N.; Verreault, J.; Labadie, P.; Budzinski, H.; Wingfield, J.C.; Chastel, O. (Journal article; Peer reviewed, 2015)The role of polychlorinated biphenyls (PCBs) on exposure-related endocrine effects has been poorly investigated in wild birds. This is the case for stress hormones including corticosterone (CORT). Some studies have suggested ... -
