Circum-Arctic distribution of chemical anti-herbivore compounds suggests biome-wide trade-off in defence strategies in Arctic shrubs
Lindén, Elin; te Beest, Mariska; Aubreu, Ilka; Moritz, Thomas; Sundqvist, Maja K.; Barrio, Isabel C.; Boike, Julia; Bryant, John P.; Bråthen, Kari Anne; Buchwal, Agata; Bueno, C.

Less defended, ... -
A circumpolar study unveils a positive non-linear effect oftemperature on arctic arthropod availability that may reduce therisk of warming-induced trophic mismatch for breeding shorebirds
Chagnon-Lafortune, Aurélie; Duchesne, Éliane; Legagneux, Pierre; McKinnon, Laura; Reneerkens, Jeroen; Casajus, Nicolas; Abraham, Kenneth F.; Bolduc, Élise; Brown, Glen S.; Brown, Stephen C.; Gates, H. River; Gilg, Olivier; Giroux, Marie-Andrée; Gurney, Kirsty E.B.; Kendall, Steve; Kwon, Eunbi; Lanctot, Richard B.; Lank, David B.; Lecomte, Nicolas; Leung, Maria; Liebezeit, Joseph R.; Morrison, R. I. Guy; Nol, Erica; Payer, David C.; Reid, Donald; Ruthrauff, Daniel; Saalfeld, Sarah T.; Sandercock, Brett Kevin; Smith, Paul A.; Schmidt, Niels Martin; Tulp, Ingrid; Ward, David H.; Høye, Toke T.; Berteaux, Dominique; Bêty, Joël (Peer reviewed; Journal article, 2024)Seasonally abundant arthropods are a crucial food source for many migratorybirds that breed in the Arctic. In cold environments, the growth and emergence ofarthropods are particularly tied to temperature. Thus, the phenology ... -
Flexibility in otherwise consistent non-breeding movements of a long-distance migratory seabird, the long-tailed skua
van Bemmelen, Rob; Moe, Børge; Hanssen, Sveinn Are; Schmidt, Niels Martin; Hansen, Jannik; Lang, Johannes; Sittler, Benoit; Bollache, Loïc; Tulp, Ingrid; Klaassen, Raymond; Gilg, Olivier (Journal article; Peer reviewed, 2017-02-15)Quantifying within- and between-individual variation in animal migration strategies is a first step towards our understanding of the ability of migrants to adjust to changes in the en - vironment. We studied consistency ... -
Muskox status, recent variation, and uncertain future
Cuyler, Christine; Rowell, Janice; Adamczewski, Jan; Anderson, Morgan; Blake, John; Bretten, Tord; Brodeur, Vincent; Campbell, Mitch; Checkley, Sylvia L.; Cluff, H. Dean; Côté, Steeve D.; Davison, Tracy; Dumond, Mathieu; Ford, Barrie; Gruzdev, Alexander; Gunn, Anne; Jones, Patrick; Kutz, Susan; Leclerc, Lisa-Marie; Mallory, Conor; Mavrot, Fabien; Mosbacher, Jesper Bruun; Okhlop, Innokentiy Mikhailovich; Reynolds, Patricia; Schmidt, Niels Martin; Sipko, Taras; Suitor, Mike; Tomaselli, Matilde; Ytrehus, Bjørnar (Journal article; Peer reviewed, 2019)Muskoxen (Ovibos moschatus) are an integral component of Arctic biodiversity. Given low genetic diversity, their ability to respond to future and rapid Arctic change is unknown, although paleontological history demonstrates ... -
Show Me Your Rump Hair and I Will Tell You What You Ate – The Dietary History of Muskoxen (Ovibos moschatus) Revealed by Sequential Stable Isotope Analysis of Guard Hairs
Mosbacher, Jesper Bruun; Michelsen, Anders; Stelvig, Mikkel; Hendrichsen, Ditte Katrine; Schmidt, Niels Martin (Peer reviewed; Journal article, 2016)The nutritional state of animals is tightly linked to the ambient environment, and for northern ungulates the state strongly influences vital population demographics, such as pregnancy rates. Continuously growing tissues, ... -
