      Reproductive timing in many taxa plays a key role in determining breeding productivity1, and is often sensitive to climatic conditions2. Current climate change may alter the timing of breeding at different rates across ...

    • Isbjørnens effekt på fugl i et arktisk klima i endring. Sluttrapport for Svalbards miljøvernfond

      Arktis blir stadig varmere og utbredelsen av havis blir mindre. Det forandrer leveområdet til de mange artene som er avhengige av havis. Isbjørnen er avhengig av havis for å jakte på sel, og økende lengde på den isfrie ...

    • Later at higher latitudes: large-scale variability in seabird breeding timing and synchronicity 

      Burr, Zofia M.; Varpe, Øystein; Anker-Nilssen, Tycho; Erikstad, Kjell E; Descamps, Sébastien; Barrett, Robert T; Bech, Claus; Christensen-Dalsgaard, Signe; Lorentsen, Svein-Håkon; Moe, Børge; Reiertsen, Tone Kristin; Strøm, Hallvard (Peer reviewed; Journal article, 2016)
      In seasonal environments, organisms are expected to optimally schedule reproduction within an annual range of environmental conditions. Latitudinal gradients generate a range of seasonality to which we can expect adaptations ...

    • 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 ...
