• Direct and indirect effects of environmental drivers on reindeer reproduction 

      Henden, John-André; Tveraa, T.; Stien, Audun; Mellard, Jarad; Marolla, Filippo; Ims, Rolf Anker; Yoccoz, Nigel (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-27)
      The impact of climate change on the dynamics of populations has been well documented and is widespread. However, weather variability influences populations both directly and indirectly, and is mediated by species interactions. This complexity may impede proper climate impact assessments. Hence, predicting the consequences of climate change may require including processes that occur both with time ...
    • Effect of scavenging on predation in a food web 

      Mellard, Jarad; Hamel, Sandra; Henden, John-André; Ims, Rolf Anker; Stien, Audun; Yoccoz, Nigel (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-26)
      <ol> <li>The fasting endurance hypothesis (FEH) predicts strong selection for large body size in mammals living in environments where food supply is interrupted over prolonged periods of time. The Arctic is a highly seasonal and food-restricted environment, but contrary to predictions from the FEH, empirical evidence shows that Arctic mammals are often smaller than their temperate conspecifics. ...
    • Food web approach for managing Arctic wildlife populations in an era of rapid environmental change 

      Mellard, Jarad; Henden, John-André; Pedersen, Åshild Ønvik; Marolla, Filippo; Hamel, Sandra; Yoccoz, Nigel; Ims, Rolf Anker (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-28)
      Scientists and wildlife managers implementing adaptive monitoring and management schemes, are tasked with providing predictions of population responses to harvest and environmental changes. Such predictions are useful not only to forecast direct effects of climate, productivity, land use, or habitat degradation, but also changes in the food web, such as expanding/increasing species that are predators, ...
    • Life-cycle analysis of an endangered migratory goose to assess the impact of conservation actions on population recovery 

      marolla, Filippo; Aarvak, Tomas; Hamel, Sandra; Ims, Rolf Anker; Kéry, Marc; Mellard, Jarad; Nater, Chloé Rebecca; Schaub, Michael; Vougioukalou, Manolia; Yoccoz, Nigel; Øien, Ingar Jostein (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-29)
      Evaluating the effectiveness of conservation actions is challenging for migratory species because a population can be impacted anywhere along its route. Conservation actions for the critically endangered Fennoscandian lesser white-fronted goose population include culling of red foxes in the breeding area and habitat improvements and reduction of illegal hunting in the non-breeding areas. One goal ...
