      Descamps, Sebastien; Ramírez, Francisco; Benjaminsen, Sigurd; Anker-Nilssen, Tycho; Barrett, Robert; Burr, Zofia; Christensen-Dalsgaard, Signe; Erikstad, Kjell E; Irons, David B.; Lorentsen, Svein Håkon; Mallory, Mark L; Robertson, Gregory J.; Reiertsen, Tone Kristin; Strøm, Hallvard; Varpe, Øystein; Lavergne, Sébastien (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-31)
      The timing of annual events such as reproduction is a critical component of how free‐living organisms respond to ongoing climate change. This may be especially true in the Arctic, which is disproportionally impacted by climate warming. Here, we show that Arctic seabirds responded to climate change by moving the start of their reproduction earlier, coincident with an advancing onset of spring and ...

    • Inter-population synchrony in adult survival and effects of climate and extreme weather in non-breeding areas of Atlantic puffins 

      Reiertsen, Tone Kristin; Layton-Matthews, Kate; Erikstad, K.E.; Hodges, Kevin I.; Ballesteros, Manuel; Anker-Nilssen, Tycho; Barrett, R.T.; Benjaminsen, Sigurd; Bogdanova, M.; Christensen-Dalsgaard, Signe; Daunt, Francis; Dehnhard, Nina; Harris, Michael P.; Langset, Magdalene; Lorentsen, Svein-Håkon; Newell, Mark; Bråthen, Vegard Sandøy; Støyle-Bringsvor, I.; Systad, Geir Helge Rødli; Wanless, Sarah (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-14)
      Seabirds are undergoing drastic declines globally and spend the non-breeding season at sea, making it challenging to study the drivers of their survival. Harsh weather and changes in climate conditions can have large impacts on seabird population dynamics through increased mortality. The intensity and persistence of extreme events are forecasted to increase with global warming. As shared conditions ...
