    • Don't go chasing the ghosts of the past: habitat selection and site fidelity during calving in an Arctic ungulate 

      Paulsen, Ingrid M.; Soininen, Eeva M; Ravolainen, Virve; Loe, Leif Egil; Hansen, Brage Bremset; Irvine, Justin R; Stien, Audun; Ropstad, Erik; Veiberg, Vebjørn; Fuglei, Eva; Pedersen, Åshild Ønvik (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-01)
      Predator avoidance and food availability are both factors known to influence habitat selection and site fidelity around calving in caribou and reindeer. Here, we assess habitat selection and site fidelity during the calving period in the solitary, Arctic Svalbard reindeer Rangifer tarandus platyrhynchus, which is subject to limited predation risk and human disturbance. In this largely predator-free ...

    • How Many Reindeer? UAV Surveys as an Alternative to Helicopter or Ground Surveys for Estimating Population Abundance in Open Landscapes 

      Paulsen, Ingrid M.; Pedersen, Åshild Ø; Hann, Richard; Blanchet, Marie-Anne; Eischeid, Isabell; van Hazendonk, Charlotte Maartje; Ravolainen, Virve; Stien, Audun; Le Moullec, Mathilde (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-12-20)
      Conservation of wildlife depends on precise and unbiased knowledge on the abundance and distribution of species. It is challenging to choose appropriate methods to obtain a sufficiently high detectability and spatial coverage matching the species characteristics and spatiotemporal use of the landscape. In remote regions, such as in the Arctic, monitoring efforts are often resource-intensive and there ...
