    • Foraging tactics in dynamic sea-ice habitats affect individual state in a long-ranging seabird 

      Tarroux, Arnaud; Cherel, Yves; Fauchald, Per; Kato, Akiko; Love, Oliver P.; Ropert-Coudert, Yan; Spreen, Gunnar; Varpe, Øystein; Weimerskirch, Henri; Yoccoz, Nigel; Zahn, Sandrine; Descamps, Sebastien (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-13)
      <ol> <li>Individual heterogeneity in diet and foraging behaviour is common in wild animal populations, and can be a strong determinant of how populations respond to environmental changes. Within populations, variation in foraging behaviour and the occurrence of individual tactics in relation to resources distribution can help explain differences in individual fitness, and ultimately identify important ...

    • Telomere length in relation to persistent organic pollutant exposure in white-tailed eagle (Haliaeetus albicilla) nestlings from Sweden sampled in 1995-2013 

      Hansen, Elisabeth; Skotnes, Tove; Bustnes, Jan Ove; Igor, Eulaers; Sun, Jiachen; Covaci, Adrian; Bårdsen, Bård-Jørgen; Zahn, Sandrine; Criscuolo, Francois; Bourgeon, Sophie; Helander, Björn (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-10)
      Telomeres are used as biomarkers of vertebrate health because of the link between their length, lifespan, and survival. Exposure to environmental stressors appears to alter telomere dynamics, but little is known about telomere length and persistent organic pollutant (POP) exposure in wildlife. The white-tailed eagle (WTE; Haliaeetus albicilla) is an avian top predator that accumulates high levels ...
