    • The Demographic buffering hypothesis: Evidence and challenges 

      Hilde, Christoffer Høyvik; Gamelon, Marlène; Sæther, Bernt-Erik; Gaillard, Jean-Michel; Yoccoz, Nigel; Pelabon, Christophe (Peer reviewed; Journal article, 2020)
      In (st)age-structured populations, the long-run population growth rate is negatively affected by temporal variation in vital rates. In most cases, natural selection should minimize temporal variation in the vital rates to ...

    • Demographic buffering of vital rates in age-structured populations 

      Hilde, Christoffer Høyvik (Doctoral theses at NTNU;2021:353, Doctoral thesis, 2021)
      Stochastic demography is essential to accurately predict how populations persist in variable environments. In age- or stage-structured populations, the long-run growth rate is negatively affected by temporal variance in ...

    • Mind the wind: microclimate effects on incubation effort of an arctic seabird 

      Hilde, Christoffer Høyvik; Pélabon, Christophe; Guéry, Loreleï; Gabrielsen, Geir Wing; Descamps, Sébastien (Journal article; Peer reviewed, 2016-02-21)
      The energetic costs of reproduction in birds strongly depend on the climate experienced during incubation. Climate change and increasing frequency of extreme weather events may severely affect these costs, especially for ...

    • On the use of the coefficient of variation to quantify and compare trait variation 

      Pelabon, Christophe; Hilde, Christoffer Høyvik; Einum, Sigurd; Gamelon, Marlène (Peer reviewed; Journal article, 2020)
      Meaningful comparison of variation in quantitative trait requires controlling for both the dimension of the varying entity and the dimension of the factor generating variation. Although the coefficient of variation (CV; ...

    • Raising offspring increases ageing: Differences in senescence among three populations of a long-lived seabird, the Atlantic puffin 

      Landsem, Terje Lorentzen; Yoccoz, Nigel Gilles; Layton-Matthews, Kate; Hilde, Christoffer Høyvik; Harris, Michael P; Wanless, Sarah; Daunt, Francis; Reiertsen, Tone Kristin; Erikstad, Kjell E.; Anker-Nilssen, Tycho (Peer reviewed; Journal article, 2023)
      1. Actuarial senescence, the decline of survival with age, is well documented in the wild. Rates of senescence vary widely between taxa, to some extent also between sexes, with the fastest life histories showing the highest ...
