Age-Related Mercury Contamination and Relationshipwith Luteinizing Hormone in a Long-Lived Antarctic Bird
Tartu, Sabrina; Bustamante, Paco; Goutte, Aurélie; Weimerskirch, Henri; Bustnes, Jan Ove; Chastel, Olivier (Journal article; Peer reviewed, 2014)Seabirds, as long-lived top predators, accumulate contaminants such as mercury (Hg), an established endocrine disruptor. In long lived species hormonal secretion varies with age; therefore, Hg-induced endocrine disruption ... -
Black-legged kittiwakes as messengers of Atlantification in the Arctic
Vihtakari, Mikko; Welcker, Jorg; Moe, Børge; Chastel, Olivier; Tartu, Sabrina; Hop, Haakon; Bech, Claus; Descamps, Sébastien; Gabrielsen, Geir W. (Journal article; Peer reviewed, 2018)Climate warming is rapidly altering marine ecosystems towards a more temperate state on the European side of the Arctic. However, this “Atlantification” has rarely been confirmed, as long-term datasets on Arctic marine ... -
Demographic responses of Arctic seabirds to spring sea-ice variations
Sauser, Christophe; Angelier, F.; Blévin, Pierre; Chastel, O.; Gabrielsen, Geir W.; Jouanneau, W.; Kato, A.; Moe, Børge; Ramírez, F.; Tartu, Sabrina; Descamps, Sebastien (Peer reviewed; Journal article, 2023)The Arctic experiences a rapid retreat of sea-ice, particularly in spring and summer, which may dramatically affect pagophilic species. In recent years, the decline of many Arctic seabird populations has raised concerns ... -
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 ... -
Exposure to oxychlordane is associated with shorter telomeres in arctic breeding kittiwakes
Blévin, Pierre; Angelier, Frédéric; Tartu, Sabrina; Ruault, Stéphanie; Bustamante, Paco; Herzke, Dorte; Moe, Børge; Bech, Claus; Gabrielsen, Geir W.; Bustnes, Jan Ove; Chastel, Olivier (Journal article; Peer reviewed, 2016) -
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 ... -
Long-term tracking of an Arctic-breeding seabird indicates high fidelity to pelagic wintering areas
Léandri-Breton, Don-Jean; Tarroux, Arnaud; Elliott, Kyle H.; Legagneux, Pierre; Angelier, Frédéric; Blévin, Pierre; Bråthen, Vegard Sandøy; Fauchald, Per; Goutte, Aurélie; Jouanneau, William; Tartu, Sabrina; Moe, Børge; Chastel, Olivier (Peer reviewed; Journal article, 2021)Site fidelity is driven by predictable resource distributions in time and space. However, intrinsic factors related to an individual’s physiology and life-history traits can contribute to consistent foraging behaviour and ... -
Mercury exposure, stress and prolactin secretion in an Arctic seabird: an experimental study
Tartu, Sabrina; Bustamante, Paco; Angelier, Frédéric; Lendvai, Adam Z.; Moe, Børge; Blévin, Pierre; Bech, Claus; Gabrielsen, Geir W.; Bustnes, Jan Ove; Chastel, Olivier (Journal article; Peer reviewed, 2016)Life-history theory predicts that long-lived organisms should reduce parental effort under inclement environmental conditions in order to favour long-term survival. Seabirds are long-lived top predators often exposed to ... -
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 ... -
Survival rate and breeding outputs in a high Arctic seabird exposed to legacy persistent organic pollutants and mercury
Goutte, Aurélie; Barbraud, Christophe; Herzke, Dorte; Bustamante, Paco; Angelier, Frédéric; Tartu, Sabrina; Clement-Chastel, Celine; Moe, Børge; Bech, Claus; Gabrielsen, Geir W.; Bustnes, Jan Ove; Chastel, Olivier (Journal article; Peer reviewed, 2015)Chronic exposure to pollutants may represent a threat for wildlife.We tested whether adult survival rate, breeding probability and breeding success the year of sampling and the following year were affected by blood levels ... -
Temporal variation in circulating concentrations of organochlorine pollutants in a pelagic seabird breeding in the high arctic
Bustnes, Jan Ove; Bårdsen, Bård-Jørgen; Moe, Børge; Herzke, Dorte; Hanssen, Sveinn Are; Sagerup, Kjetil; Bech, Claus; Nordstad, Tore; Chastel, Olivier; Tartu, Sabrina; Gabrielsen, Geir W. (Journal article; Peer reviewed, 2017)The present study explored short-term temporal variations in circulating concentrations of 3 legacy organochlorines with different physicochemical properties (polychlorinated biphenyl 153 [PCB-153], p,p0-dichlorodiphenyl ... -
The stress of being contaminated? Adrenocortical function and reproduction in relation to persistent organic pollutants in female black legged kittiwakes
Tartu, Sabrina; Angelier, Frédéric; Herzke, Dorte; Moe, Børge; Bech, Claus; Gabrielsen, Geir W.; Bustnes, Jan Ove; Chastel, Olivier (Journal article; Peer reviewed, 2014)High levels of environmental pollutants such as persistent organic pollutants (POPs) including PCB and DDT have been found in the Arctic and many of those pollutants may impair reproduction through endocrine disruption. ...
