Adaptation to the High-Arctic island environment despite long-term reduced genetic variation in Svalbard reindeer
Dussex, Nicolas; Tørresen, Ole Kristian; van der Valk, Tom; Le Moullec, Mathilde; Veiberg, Vebjørn; Tooming-Klunderud, Ave; Skage, Morten; Garmann-Aarhus, Benedicte; Wood, Jonathan; Rasmussen, Jacob Agerbo; Pedersen, Åshild Ønvik; Martin, Sarah Louise; Røed, Knut; Jakobsen, Kjetill Sigurd; Dalén, Love; Hansen, Brage Bremset; Martin, Michael David (Peer reviewed; Journal article, 2023)Typically much smaller in number than their mainland counterparts, island populations are ideal systems to investigate genetic threats to small populations. The Svalbard reindeer (Rangifer tarandus platyrhynchus) is an ... -

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 ... -
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 (Peer reviewed; Journal article, 2021)Arctic, calving, food availability, GPS, Rangifer tarandus platyrhynchus, remote sensing, site fidelity -
High seasonal overlap in habitat suitability in a nonmigratory High Arctic ungulate
Pedersen, Åshild Ønvik; Soininen, Eeva M; Hansen, Brage Bremset; Le Moullec, Mathilde; Loe, Leif Egil; Paulsen, I.M.G.; Eischeid, Isabell; Karlsen, Stein Rune; Ropstad, Erik; Stien, Audun; Tarroux, Arnaud; Tømmervik, Hans; Ravolainen, Virve (Peer reviewed; Journal article, 2023)Understanding drivers of space use and habitat selection is essential for management and conservation, especially under rapid environmental change. Here, we develop summer and winter habitat suitability models for the ... -
Low spatial habitat overlap of herbivores in the High Arctic tundra
Ravolainen, Virve; Paulsen, Ingrid Marie Garfelt; Eischeid, Isabell; Forbey, Jennifer Sorensen; Fuglei, Eva; Hájek, Tomás; Hansen, Brage Bremset; Loe, Leif Egil; Macek, Petr; Madsen, Jesper; Soininen, Eeva M; Speed, James David Mervyn; Stien, Audun; Tømmervik, Hans; Pedersen, Åshild Ønvik (Peer reviewed; Journal article, 2024)Herbivores play a crucial role in shaping tundra ecosystems through their effects on vegetation, nutrient cycling, and soil abiotic factors. Understanding their habitat use, co-occurrence, and overlap is therefore essential ... -
The neglected season: Warmer autumns counteract harsher winters and promote population growth in Arctic reindeer
Loe, Leif Egil; Liston, Glen E.; Pigeon, Gabriel; Barker, Kristin; Horvitz, Nir; Stien, Audun; Forchhammer, Mads C.; Getz, Wayne M.; Irvine, Robert Justin; Lee, Aline Magdalena; Movik, Lars K.; Mysterud, Atle; Pedersen, Åshild Ønvik; Reinking, Adele K.; Ropstad, Erik; Trondrud, Liv Monica; Tveraa, Torkild; Veiberg, Vebjørn; Hansen, Brage Bremset; Albon, Steve D. (Peer reviewed; Journal article, 2020)Arctic ungulates are experiencing the most rapid climate warming on Earth. While concerns have been raised that more frequent icing events may cause die-offs, and earlier springs may generate a trophic mismatch in phenology, ... -
Sea ice loss increases genetic isolation in a high Arctic ungulate metapopulation
Peeters, Bart; Le Moullec, Mathilde; Raeymaekers, Joost A. M.; Fredricson Marquez, Jonatan; Røed, Knut; Pedersen, Åshild Ønvik; Veiberg, Vebjørn; Loe, Leif Egil; Hansen, Brage Bremset (Peer reviewed; Journal article, 2019)Sea ice loss may have dramatic consequences for population connectivity, extinction–colonization dynamics, and even the persistence of Arctic species subject to climate change. This is of particular concern in face of ... -
