• Distinct genetic clustering in the weakly diferentiated polar cod, Boreogadus saida Lepechin, 1774 from East Siberian Sea to Svalbard 

      Sanchez, Maria Quintela; Bhat, Shripathi; Præbel, Kim; Gordeeva, Natalia; Seljestad, Gaute Wilhelmsen; Hanebrekke, Tanja Lexau; Mateos-Rivera, Alejandro; Vikebø, Frode Bendiksen; Zelenia, Daria; Cheng, Chi-Hing Christina; Johansen, Torild (Journal article; Peer reviewed, 2021)
      The cold-adapted polar cod Boreogadus saida, a key species in Arctic ecosystems, is vulnerable to global warming and ice retreat. In this study, 1257 individuals sampled in 17 locations within the latitudinal range of ...
    • Hiding in the background: community-level patterns in invertebrate herbivory across the tundra biome 

      Rheubottom, Sarah I.; Barrio, Isabel C.; Kozlov, Mikhail V.; Alatalo, Juha M.; Andersson, Tommi; Asmus, Ashley L.; Baubin, Capucine; Brearley, Francis Q.; Egelkraut, Dagmar; Ehrich, Dorothee; Gauthier, Gilles; Jonsdottir, Ingibjørg; Konieczka, Sophia; Lévesque, Esther; Olofsson, Johan; Prevéy, Janet S.; Slevan-Tremblay, Guillaume; Sokolov, Aleksandr; Sokolova, Natalia; Sokovnina, Svetlana; Speed, James David Mervyn; Suominen, Otso; Zverev, Vitali; Hik, David S. (Peer reviewed; Journal article, 2019)
      Invertebrate herbivores depend on external temperature for growth and metabolism. Continued warming in tundra ecosystems is proposed to result in increased invertebrate herbivory. However, empirical data about how current ...
    • Nutrient fuxes from an Arctic seabird colony to the adjacent coastal marine ecosystem 

      Finne, Eirik Aasmo; Varpe, Øystein; Durant, Joël; Gabrielsen, Geir W.; Poste, Amanda (Journal article; Peer reviewed, 2022)
      Seabirds are important vectors for nutrient transfer across ecosystem boundaries. In this seasonal study, we evaluate the impact of an Arctic colony (Alkhornet, Svalbard) of Black-legged Kittiwakes (Rissa tridactyla) and ...
    • Ontogenetic movements of cod in Arctic fjords and the Barents Sea as revealed by otolith microchemistry 

      Andrade Rodriguez, Hector Antonio; van der Sleen, Peter; Black, Bryan A.; Godiksen, Jane Aanestad; Locke V, William L.; Carroll, Michael Leslie; Ambrose, William G. Jr.; Geffen, Audrey J. (Journal article; Peer reviewed, 2020-04-06)
      The distribution of Atlantic cod (Gadus morhua) in northern Norwegian waters is expanding eastward and northward in the Barents Sea and along western Svalbard. In the Arctic fjords of Svalbard, cod has become abundant, but ...
    • The terrestrial invertebrate fauna of Edgeøya, Svalbard: Arctic landscape community composition reflects biogeography patterns 

      Ávila-Jimenéz, Maria Luisa; Solhøy, Torstein; Gwiazdowicz, Dariusz J.; Fjellberg, Arne; Dózsa‑Farkas, K.; Monson, F; De Smet, Willem H.; Stur, Elisabeth; Ekrem, Torbjørn; Coulson, Stephen James (Peer reviewed; Journal article, 2019-05)
      Colonisation and immigration history is often neglected as a factor when investigating community or species distribution patterns. However, for dynamic systems that are still reacting to large-scale environmental change, ...
    • Xenobiotic metabolism and its physiological consequences in high‑Antarctic Notothenioid fishes 

      Strobel, Anneli; Lille-Langøy, Roger; Segner, Helmut; Burkhardt-Holm, Patricia; Goksøyr, Anders; Karlsen, Odd André (Journal article; Peer reviewed, 2022)
      The Antarctic ecosystem is progressively exposed to anthropogenic contaminants, such as polycyclic aromatic hydrocarbons (PAHs). So far, it is largely unknown if PAHs leave a mark in the physiology of high-Antarctic fish. ...
