    Engen, Sigrid; Runge, Claire Alice; Brown, Greg; Fauchald, Per; Nilsen, Lennart; Hausner, Vera Helene (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-12-14)
    Protected area management can be highly contentious. Information about the acceptability of conservation actions can help environmental authorities design policies that are accepted locally, and identify potential areas of conflict between land users and conservation objectives. In this study, we implemented a spatially-explicit method for eliciting public preferences for land use and conservation ...
  • Effects of acute exposure to dispersed oil and burned oil residue on long-term survival, growth, and reproductive development in polar cod (Boreogadus saida) 

    Bender, Morgan Lizabeth; Frantzen, marianne; Camus, Lionel; Le Floch, Sebastien; Palerud, Jocelyn Hernandez; Nahrgang, Jasmine (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-05)
    The present study investigates the potential long-term physiological effects on maturing polar cod (<i>Boreogadus saida</i>), an Arctic key species, after an acute exposure (48 h) to environmentally realistic concentrations of either mechanically dispersed oil (MDO), chemically dispersed oil (CDO) or burned oil residues (BO) (N = 58–60 per treatment). Following exposure, fish were monitored in a ...
  • Effects of dietary crude oil exposure on molecular and physiological parameters related to lipid homeostasis in polar cod (Boreogadus saida) 

    Vieweg, Ireen; Bilbao, Eider; Meador, James P.; Cancio, Ibon; Bender, Morgan Lizabeth; Cajaraville, Miren P.; Nahrgang, Jasmine (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03-17)
    Polar cod is an abundant Arctic key species, inhabiting an ecosystem that is subjected to rapid climate change and increased petroleum related activities. Few studies have investigated biological effects of crude oil on lipid metabolism in this species, despite lipids being a crucial compound for Arctic species to adapt to the high seasonality in food abundance in their habitat. This study examines ...
  • Local land use associated with socio-economic development in six arctic regions 

    Ehrich, Dorothee; Thuestad, Alma Elizabeth; Tømmervik, Hans; Fauchald, Per; Hausner, Vera Helene (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-04)
    The socioeconomic causes of land use change are complex. They are highly context dependent, but most often studied through case studies. Here, we use a quasi-experimental paired block design to investigate whether better access to wage income leads to more visible land use around 28 settlements in six regions of the circumpolar Arctic. We mapped visible land use on high-resolution satellite images ...
  • Small copepods matter: Population dynamics of Microsetella norvegica in a high-latitude coastal ecosystem 

    Svensen, Camilla; Antonsen, Maria Terese; Reigstad, Marit (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-06-04)
    We investigated the population dynamics of a small and little-studied harpacticoid copepod, <i>Microsetella norvegica</i>, in a sub-Arctic Norwegian fjord (Balsfjord 69°N). We sampled with a 90 μm mesh WP-2 net and a 20 L Go-Flo bottle and found that the WP-2 under-sampled all juvenile stages. The abundance and biomass were high, peaking in June with 9349 × 10-<sup>3</sup> ind. m<sup>−2</sup> and ...
  • Seasonal variation in the thermal responses to changing environmental temperature in the world's northernmost land bird 

    Nord, Andreas; Folkow, Lars (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-01-10)
    Arctic homeotherms counter challenges at high latitudes using a combination of seasonal adjustments in pelage/plumage, fat deposition and intricate thermoregulatory adaptations. However, there are still gaps in our understanding of their thermal responses to cold, particularly in Arctic birds. Here, we have studied the potential use of local heterothermy (i.e. tissue cooling that can contribute to ...
  • Correlation between number of human cases of myiasis caused by the reindeer warble fly (Hypoderma tarandi) and weather conditions during summer in northern Scandinavia 

    Landehag, Jörgen; Skogen, Andreas; Nilssen, Arne Claus (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-12-19)
    The reindeer warble fly (<i>Hypoderma tarandi</i>) causes myiasis in reindeer and caribou (<i>Rangifer tarandus and subspecies</i>) and aberrant hosts such as humans. Of 22 human cases reported 1982–2016, 16 were children and 18 were residents in or visited northern parts of Norway or Sweden. Of a series of 39 new human cases in Norway 2011–2016 (reported 2017), 32 were children, 32 were resident ...
  • Divergent responses of Atlantic cod to ocean acidification and food limitation 

    Stiasny, Martina H.; Sswat, Michael; Mittermayer, Felix H.; Falk-Petersen, Inger-Britt; Schnell, Nalani K.; Puvanendran, Velmurugu; Mortensen, Atle; Reusch, Thorsten B.H.; Clemmesen, Catriona (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-12-20)
    In order to understand the effect of global change on marine fishes, it is imperative to quantify the effects on fundamental parameters such as survival and growth. Larval survival and recruitment of the Atlantic cod (<i>Gadus morhua</i>) was found to be heavily impaired by end‐of‐century levels of ocean acidification. Here, we analysed larval growth among 35‐36 days old surviving larvae, along with ...
  • High tolerance of a high-arctic willow and graminoid to simulated ice encasement 

    Bjerke, Jarle W.; Elverland, Ellen; Jaakola, Laura; Lund, Leidulf; Zagajewski, Bogdan; Bochenek, Zbigniew; Kłos, Andrzej; Tømmervik, Hans (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-12-17)
    Climate change-induced snow thaw and subsequent accumulation of ice on the ground is a potential, major threat to snow-dominated ecosystems. While impacts of ground-ice on arctic wildlife are well explored, the impacts on tundra vegetation is far from understood. We therefore tested the vulnerability of two high-arctic plants, the prostrate shrub <i>Salix polaris</i> and the graminoid <i>Luzula ...
  • The advective origin of an under-ice spring bloom in the Arctic Ocean using multiple observational platforms 

    Johnsen, Geir; Norli, Marit; Moline, Mark A.; Robbins, Ian; Quillfeldt, Cecilie von; Sørensen, Kai; Cottier, Finlo Robert; Berge, Jørgen (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-02-13)
    Under-ice blooms of phytoplankton in the Chukchi Sea have been observed, with strong implications for our understanding of the production regimes in the Arctic Ocean. Using a combination of satellite remote sensing of phytoplankton biomass, in situ observations under sea ice from an autonomous underwater vehicle (AUV), and in vivo photophysiology, we examined the composition, magnitude and origin ...

    Routti, Heli; Diot, Beatrice; Panti, Cristina; Duale, Nur; Fossi, Maria Cristina; Harju, Mikael; Kovacs, Kit M.; Lydersen, Christian; Scotter, Sophie; Villanger, Gro Dehli; Bourgeon, Sophie (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-30)
    Marine mammals in the Barents Sea region have among the highest levels of contaminants recorded in the Arctic and the Atlantic walrus (<i>Odobenus rosmarus rosmarus</i>) is one of the most contaminated species within this region. We therefore investigated the relationships bewteen blubber concentrations of lipophilic persistent organic pollutants (POPs) and plasma concentrations of perfluoroalkyl ...
  • Risk assessment on import of Australian redclaw crayfish to Norway. Opinion of the Panel on Animal Health and Welfare of the Norwegian Scientific Committee for Food Safety 

    Bergh, Øivind; Das Neves, Carlos G; Hindar, Kjetil; Høgåsen, Helga Rachel; Jelmert, Anders; Vrålstad, Trude; Agdestein, Angelika; Asmyhr, Maria Gulbrandsen; Basic, Dean; Brun, Edgar; Bøe, Knut Egil; Godfroid, Jacques; Gudding, Roar; Hoel, Kristian; Mejdell, Cecilie Marie; Mortensen, Stein; Rimstad, Espen; Hjeltnes, Brit (Research report; Forskningsrapport, 2016-11-30)
    <i>Main message</i>: It seems unlikely that the Australian red claw clayfish will establish reproductive populations under Norwegian climate conditions, but hitchhiker organisms and infectious agents could potentially follow the import, and unless managed, may pose risks to biodiversity and aquatic animal health. This is the conclusion in a risk assessment from the Norwegian Scientific Committee for ...

    The tundra is warming more rapidly than any other biome on Earth, and the potential ramifications are far-reaching because of global feedback effects between vegetation and climate. A better understanding of how environmental factors shape plant structure and function is crucial for predicting the consequences of environmental change for ecosystem functioning. Here we explore the biome-wide relationships ...
  • Northern cod species face spawning habitat losses if global warming exceeds 1.5°C 

    Dahlke, Flemming T.; Butzin, Martin; Nahrgang, Jasmine; Puvanendran, Velmurugu; Mortensen, Atle; Pörtner, Hans-Otto; Storch, Daniela (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-28)
    Rapid climate change in the Northeast Atlantic and Arctic poses a threat to some of the world’s largest fish populations. Impacts of warming and acidification may become accessible through mechanism-based risk assessments and projections of future habitat suitability. We show that ocean acidification causes a narrowing of embryonic thermal ranges, which identifies the suitability of spawning ...
  • Ballasting by cryogenic gypsum enhances carbon export in a Phaeocystis under-ice bloom 

    Wollenburg, JE; Katlein, C; Nehrke, Gernot; Nöthig, E.-M; Matthiessen, J; Wolf-Gladrow, Dieter A.; Nikolopoulos, A.; Gazquez-Sanchez, F; Rossmann, L; Assmy, Philipp; Babin, Marcel; Bruyant, F; Beaulieu, Michaël; Dybwad, Christine; Peeken, Ilka (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-16)
    Mineral ballasting enhances carbon export from the surface to the deep ocean; however, little is known about the role of this process in the ice-covered Arctic Ocean. Here, we propose gypsum ballasting as a new mechanism that likely facilitated enhanced vertical carbon export from an under-ice phytoplankton bloom dominated by the haptophyte Phaeocystis. In the spring 2015 abundant gypsum crystals ...
