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 ... -

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 ... -
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.
