    • A Century of Conservation: The Ongoing Recovery of Svalbard Reindeer 

      Le Moullec, Mathilde; Pedersen, Åshild Ønvik; Stien, Audun; Rosvold, Jørgen; Hansen, Brage Bremset (Peer reviewed; Journal article, 2019)
      Several caribou and reindeer (Rangifer tarandus) populations have experienced recent population declines, often attributed to anthropogenic stressors such as harvesting, landscape fragmentation, and climate change. Svalbard ...

    • Behavioral buffering of extreme weather events in a high-Arctic herbivore 

      Loe, Leif Egil; Hansen, Brage Bremset; Stien, Audun; Albon, Steve D.; Bischof, Richard; Carlsson, Anja M.; Irvine, Justin; Meland, Morten; Rivrud, Inger Maren; Ropstad, Erik; Veiberg, Vebjørn; Mysterud, Atle (Journal article; Peer reviewed, 2016)
      As global warming advances, there is a growing concern about the impact of extreme weather events on ecosystems. In the Arctic, more frequent unseasonal warm spells and rain-on- snow events in winter cause changes in ...

    • Changes in greening in the High Arctic - insights from a 30-year AVHRR max NDVI dataset for Svalbard 

      Vickers, Hannah; Høgda, Kjell Arild; Solbø, Stian; Karlsen, Stein Rune; Tømmervik, Hans; Aanes, Ronny; Hansen, Brage Bremset (Journal article; Peer reviewed, 2016)
      Satellite-aided studies of vegetation cover, biomass and productivity are becoming increasingly important formonitoring the effects of a changing climate on the biosphere. With their large spatial coverage and good temporal ...

    • Climate and density-dependence cause changes in adult sex ratio in a large Arctic herbivore 

      Peeters, Bart; Veiberg, Vebjørn; Pedersen, Åshild Ønvik; Stien, Audun; Irvine, Robert Justin; Aanes, Ronny; Sæther, Bernt-Erik; Strand, Olav; Hansen, Brage Bremset (Journal article; Peer reviewed, 2017)
      Peeters, B., V. Veiberg, A. Ø. Pedersen, A. Stien, R. J. Irvine, R. Aanes, B.-E. Sæther, O. Strand, and B. B. Hansen. 2017. Climate and density dependence cause changes in adult sex ratio in a large Arctic herbivore. ...

    • Contrasting genomic consequences of anthropogenic reintroduction and natural recolonization in high-arctic wild reindeer 

      Burnett, Hamish Andrew; Bieker, Vanessa Carina; Le Moullec, Mathilde; Peeters, Bart; Rosvold, Jørgen; Pedersen, Åshild Ønvik; Dalén, Love; Loe, Leif Egil; Jensen, Henrik; Hansen, Brage Bremset; Martin, Michael David (Peer reviewed; Journal article, 2023)
      Anthropogenic reintroduction can supplement natural recolonization in reestablishing a species' distribution and abundance. However, both reintroductions and recolonizations can give rise to founder effects that reduce ...

    • Hunting for ecological indicators: are large herbivore skeleton measures from harvest data useful proxies for monitoring? 

      Pedersen, Åshild Ønvik; Bårdsen, Bård-Jørgen; Veiberg, Vebjørn; Irvine, Justin R; Hansen, Brage Bremset (Peer reviewed; Journal article, 2023)
      Hunter-collected data and samples are used as indices of population performance, and monitoring programs often take advantage of such data as ecological indicators. Here, we establish the relationships between measures of ...

    • Klimaeffektar på svalbardreinens kalvingstidspunkt 

      Veiberg, Vebjørn; Danielsen, Preben; Loe, Leif Egil; Stien, Audun; Peeters, Bart; Hansen, Brage Bremset; Irvine, R. Justine; Ropstad, Erik; Albon, Steve D.; Tveraa, Torkild; Varpe, Øystein (NINA Rapport;1311, Research report, 2017)

    • The role of seasonal migration in spatial population synchrony 

      Martin, Ellen Claire; Hansen, Brage Bremset; Herfindal, Ivar; Lee, Aline Magdalena (Peer reviewed; Journal article, 2023)
      Spatially synchronized population dynamics are common in nature, and understanding their causes is key for predicting species persistence. A main driver of synchrony between populations of the same species is shared ...
