    • Conservation of the endangered Arctic fox in Norway - are successful reintroductions enough? 

      Landa, Arild; Rød-Eriksen, Lars; Ulvund, Kristine R.; Jackson, Craig Ryan; Thierry, Anne-Mathilde; Flagstad, Øystein; Eide, Nina Elisabeth (Peer reviewed; Journal article, 2022)
      Translocation of captive-bred animals has become a widespread conservation practice to counteract species extinctions. We analyse and discuss the apparent success and shortcomings of Arctic fox (Vulpes lagopus) reintroductions ...

      Flagstad, Øystein; Balstad, Torveig; Østborg, Gunnel Marie; Brøseth, Henrik (NINA rapport;310, Research report, 2007)
      Flagstad, Ø., Balstad, T., Østborg, G. & Brøseth, H. 2007. DNA-basert overvåking av jerv i Nord-Norge vinteren 2006/2007. - NINA Rapport 310. 34 s. Genetiske analyser er de siste årene blitt implementert som et viktig ...

    • Down a hole: missing GPS positions reveal birth dates of an underground denning species, the red fox 

      Walton, Zea Ann; Mattisson, Jenny (Others, 2021)
      Global positioning system (GPS) technology is increasingly used to study animal behavior. However, some animals exhibit behaviors that may result in the failure to acquire a GPS position, such as for species with underground ...

    • Effect of sand texture on nest quality and mating success in a fish with parental care 

      Olsson, Karin H.; Forsgren, Elisabet; Merilaita, Sami; Kvarnemo, Charlotta; St. Mary, Colette (Journal article; Peer reviewed, 2019)
      Nest quality is an important aspect of courtship and mate choice, offering females direct benefits through offspring survival and, if it reflects male genetic quality, also indirect ones. Nest characteristics may thus ...

    • 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)

    • Multi-colony tracking reveals spatio-temporal variation in carry-over effects between breeding success and winter movements in a pelagic seabird 

      Bogdanova, Maria I.; Butler, Adam; Wanless, Sarah; Moe, Børge; Anker-Nilssen, Tycho; Frederiksen, Morten; Boulinier, Thierry; Chivers, Lorraine S.; Christensen-Dalsgaard, Signe; Descamps, Sébastien; Harris, Michael P.; Newell, Mark; Olsen, Bergur; Phillips, Richard A.; Shaw, Deryk; Steen, Harald; Strøm, Hallvard; Thórarinsson, Thorkell L; Daunt, Francis (Journal article; Peer reviewed, 2017)
      Carry-over effects, whereby events in one season have consequences in subsequent seasons, have important demographic implications. Although most studies examine carry-over effects across 2 seasons in single populations, ...

    • Parturition dates in wild Eurasian lynx: evidence of a second oestrus? 

      Mattisson, Jenny; Odden, John; Linnell, John Durrus; Painer, Johanna; Persson, Jens; Andrén, Henrik (Peer reviewed; Journal article, 2020)
      Understanding reproductive physiology of a species is important to assess their potential to respond to environmental variation and perturbation of their social system during the mating or pre-mating seasons. We report 175 ...
