Little impact of over-winter parasitism on a free-ranging ungulate in the high Arctic
Carlsson, Anja M.; Albon, Steve D.; Coulson, Stephen J.; Ropstad, Erik; Stien, Audun; Wilson, Kenneth; Loe, Leif Egil; Veiberg, Vebjørn; Irvine, Robert Justin (Journal article; Peer reviewed, 2018)1. Macroparasites have a central place in wildlife ecology because they have the potential to regulate host populations through effects on reproduction and/or survival. However, there remains a paucity of studies that have ... -

Nonlinear spatial and temporal decomposition provides insight for climate change effects on sub-Arctic herbivore populations
Correia, Hannah E.; Tveraa, Torkild; Stien, Audun; Yoccoz, Nigel (Peer reviewed; Journal article, 2022)Global temperatures are increasing, afecting timing and availability of vegetation along with relationships between plants and their consumers. We examined the efect of population density, herd body condition in the previous ... -
Population densities, vegetation green-up, and plant productivity: impacts on reproductive success and juvenile body mass in reindeer
Tveraa, Torkild; Stien, Audun; Bårdsen, Bård-Jørgen; Fauchald, Per (Peer reviewed; Journal article, 2013)Global warming is expected to cause earlier springs and increased primary productivity in the Arctic. These changes may improve food availability for Arctic herbivores, but may also have negative effects by generating a ... -
Rangifer management controls a climate-sensitive tundra state transition
Bråthen, Kari Anne; Ravolainen, Virve Tuulia; Stien, Audun; Tveraa, Torkild; Ims, Rolf Anker (Journal article; Peer reviewed, 2017)Rangifer (caribou/reindeer) management has been suggested to mitigate the temperature- driven transition of Arctic tundra into a shrubland state, yet how this happens is uncertain. Here we study this much focused ecosystem ... -
Retrospective growth analysis of the dwarf shrub Cassiope tetragona allows local estimation of vascular plant productivity in high arctic Svalbard
Milner, Jos M.; Stien, Audun; Wal, Rene van der (Journal article; Peer reviewed, 2018)Question: Vascular plant productivity of arctic tundra has often been viewed as varying little between years and thus being largely insensitive to the high inter-annual variation in summer weather conditions. Yet, ... -

The cost of migratory prey: seasonal changes in semi-domesticreindeer distribution influences breeding success of Eurasian lynx in northern Norway
Walton, Zea; Mattisson, Jenny; Linnell, John Durrus; Stien, Audun; Odden, John (Peer reviewed; Journal article, 2016)Migratory prey is a widespread phenomenon that has implications for predator – prey interactions. By creating large temporal variation in resource availability between seasons it becomes challenging for carnivores to ... -
The influence of weather conditions during gestation on life histories in a wild Arctic ungulate
Douhard, Mathieu; Loe, Leif Egil; Stien, Audun; Bonenfant, Christophe; Irvine, R. Justin; Veiberg, Vebjørn; Ropstad, Erik; Albon, Steve D. (Journal article; Peer reviewed, 2016)The internal predictive adaptive response (internal PAR) hypothesis predicts that individuals born in poor conditions should start to reproduce earlier if they are likely to have reduced performance in later life. However, ...
