A Summer Heat Wave Reduced Activity, Heart Rate, and Autumn Body Mass in a Cold-Adapted Ungulate
Trondrud, Liv Monica; Pigeon, Gabriel; Król, Elżbieta; Albon, Steve; Ropstad, Erik; Kumpula, Jouko; Evans, Alina; Speakman, John R.; Loe, Leif Egil (Peer reviewed; Journal article, 2023) -
Antler growth as a cost of reproduction in female reindeer
Loe, Leif Egil; Pigeon, Gabriel; Albon, Steve D.; Giske, Pernille Andrine Eriksdatter; Irvine, R. Justin; Ropstad, Erik; Stien, Audun; Veiberg, Vebjørn; Mysterud, Atle (Peer reviewed; Journal article, 2019)The costs of reproduction are important in shaping individual life histories, and hence population dynamics, but the mechanistic pathways of such costs are often unknown. Female reindeer have evolved antlers possibly due ... -
Context-dependent fitness costs of reproduction despite stable body mass costs in an Arctic herbivore
Pigeon, Gabriel; Albon, Steve; Loe, Leif Egil; Bischof, Richard; Bonenfant, Christophe; Forchhammer, Mads; Irvine, Robert Justin; Ropstad, Erik; Veiberg, Vebjørn; Stien, Audun (Peer reviewed; Journal article, 2021) -
Determinants of heart rate in Svalbard reindeer reveal mechanisms of seasonal energy management
Trondrud, Liv Monica; Pigeon, Gabriel; Albon, Steve; Arnold, Walter; Evans, Alina; Irvine, R. Justin; Król, Elżbieta; Ropstad, Erik; Stien, Audun; Veiberg, Vebjørn; Speakman, John R.; Loe, Leif Egil (Peer reviewed; Journal article, 2021) -
Effekter av GPS-halsbånd på kroppsvekt og reproduksjon hos simler av svalbardrein (Rangifer tarandus platyrhynchus)
Rønning, Pernille Stordal (Master thesis, 2019)De siste tiårene har forståelsen for hvordan dyrearter beveger seg i ulike miljø vært et sentralt forskningstema. Biotelemetri er et viktig verktøy for å få innsikt i arters habitatbruk og vandringsmønster, og bruk av ... -
Energetics in seasonal environments: reindeer as a case study
Trondrud, Liv Monica (PhD Thesis;2021:74, Doctoral thesis, 2021)How endothermic animals manage and allocate energy to critical processes (maintenance, reproduction, thermoregulation and activity) can determine their success and survival. The balance in energy expenditure related to ... -
Fat storage influences fasting endurance more than body size in an ungulate
Trondrud, Liv Monica; Pigeon, Gabriel; Król, Elżbieta; Albon, Steve; Evans, Alina; Arnold, Walter; Hambly, Catherine; Irvine, R. Justin; Ropstad, Erik; Stien, Audun; Veiberg, Vebjørn; Speakman, John R.; Loe, Leif Egil (Peer reviewed; Journal article, 2021)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 ... -
Hunting regulation favors slow life histories in a large carnivore
Van de Walle, Joanie; Pigeon, Gabriel; Zedrosser, Andreas; Swenson, Jon; Pelletier, Fanie (Journal article; Peer reviewed, 2018)As an important extrinsic source of mortality, harvest should select for fast reproduction and accelerated life histories. However, if vulnerability to harvest depends upon female reproductive status, patterns of selectivity ... -
Keeping cool in the warming Arctic: thermoregulatory behaviour by Svalbard reindeer (Rangifer tarandus platyrhynchus)
Williamsen, Linda; Pigeon, Gabriel; Mysterud, Atle; Stien, Audun; Forchhammer, Mads C.; Loe, Leif Egil (Peer reviewed; Journal article, 2019)In animals with long generation times, evolution of physiological and morphological traits may not be fast enough to keep up with rapid climate warming, but thermoregulatory behaviour can possibly serve as an important ... -
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, ... -
Silver spoon effects are constrained under extreme adult environmental conditions
Pigeon, Gabriel; Loe, Leif Egil; Bischof, Richard; Bonenfant, Christophe; Forchhammer, Mads C.; Irvine, R. Justin; Ropstad, Erik; Stien, Audun; Veiberg, Vebjørn; Albon, Steve (Peer reviewed; Journal article, 2019)Early-life environmental conditions may generate cohort differences in individual fitness, subsequently affecting population growth rates. Three, nonmutually exclusive hypotheses predict the nature of these fitness ... -
Stress responses to repeated captures in a wild ungulate
Trondrud, Liv Monica; Ugland, Cassandra Regine; Ropstad, Erik; Loe, Leif Egil; Albon, Steve; Stien, Audun; Evans, Alina; Thorsby, Per Medbøe; Veiberg, Vebjørn; Irvine, R. Justin; Pigeon, Gabriel (Journal article; Peer reviewed, 2022) -

Thermoregulatory behavior in a warming Arctic : bed site selection by Svalbard reindeer (Rangifer tarandus platyrhynchus) in summer
Williamsen, Linda (Master thesis, 2018)Climate change leads to rapidly increasing mean temperatures, and the climate warming is particularly pronounced in the Arctic. In Arctic mammals with long generation times, evolution of physiological and morphological ...
