    The gastrointestinal (GI) microbiome in fish plays significant roles in health and disease resistance. This investigation was accomplished to enumerate, characterize and identify the potential probiotic bacteria from three Indian Major Carps (IMCs), viz., rohu (Labeo rohita), catla (Catla catla) and mrigal (Cirrhinus mrigala) using culture dependent methods. Altogether, 105 pathogen-inhibitory ...
  • Transgenerational Health Effects of In Utero Exposure to Economic Hardship: Evidence from Preindustrial Southern Norway 

    Sari, Emre; Moilanen, Mikko; Sommerseth, Hilde Leikny (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-12)
    We studied whether in utero exposure to economic hardship during a grandmother's pregnancy has a transgenerational effect on her grandchildren's health condition. We used an individual-level three-generation data set covering people born between 1734 and 1840 in the municipality of Rendalen in Norway. We found a culling effect in which grandchildren whose grandmothers gave birth in years of economic ...
  • Development of a bio-optical model for the Barents Sea to quantitatively link glider and satellite observations 

    Kostakis, I.; Röttgers, R.; Orkney, A.; Bouman, H.A.; Porter, M.; Cottier, Finlo Robert; Berge, Jørgen; Mckee, David (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-31)
    A bio-optical model for the Barents Sea is determined from a set of in situ observations of inherent optical properties (IOPs) and associated biogeochemical analyses. The bio-optical model provides a pathway to convert commonly measured parameters from glider-borne sensors (CTD, optical triplet sensor— chlorophyll and CDOM fluorescence, backscattering coefficients) to bulk spectral IOPs ...

    Svalbard fjords are facing a significant increase in Atlantic water inflow, which influences all ecosystem components, thus the objective of this study was to assess how recent Atlantification impacts the functioning of zooplankton community. For this purpose, two year-round operating sediment traps and associated hydrographic instruments, providing continuous time series of zooplankton and sediment ...
  • Bycatch reduction in the deep-water shrimp (Pandalus borealis) trawl fishery by increasing codend mesh openness 

    Jacques, Nadine; Cerbule, Kristine; Pettersen, Hermann; Herrmann, Bent; Ingólfsson, Ólafur; Sistiaga, Manu Berrondo; Larsen, Roger B.; Brinkhof, Jesse; Grimaldo, Vela Eduardo; Brčić, Jure; Lilleng, Dagfinn (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-03)
    In most trawl fisheries, drag forces tend to close the meshes in large areas of diamond mesh codends, negatively affecting their selective potential. In the Barents Sea deep-water shrimp (Pandalus borealis) trawl fishery, selectivity is based on a sorting grid followed by a diamond mesh codend. However, the retention of juvenile fish as well as undersized shrimp is still a problem. In this study, ...
  • Immunostimulant Bathing Influences the Expression of Immune- and Metabolic-Related Genes in Atlantic Salmon Alevins 

    Figueiredo, Filipe; Kristoffersen, Harald; Bhat, Shripathi; Zhang, Zuobing; Godfroid, Jacques; Peruzzi, Stefano; Præbel, Kim; Dalmo, Roy Ambli; Xu, Xiaoli (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-29)
    Disease resistance of fish larvae may be improved by bath treatment in water containing immunostimulants. Pattern recognition receptors, such as TLR3, TLR7, and MDA5, work as an “early warning” to induce intracellular signaling and facilitate an antiviral response. A single bath of newly hatched larvae, with Astragalus, upregulated the expression of IFNα, IFNc, ISG15, MDA5, PKR, STAT1, TLR3, and ...
  • Susceptibility of polar cod (Boreogadus saida) to a model carcinogen 

    Lerebours, Adélaïde; Murzina, Svetlana; Song, You; Tollefsen, Knut-Erik; Benedetti, Maura; Regoli, Francesco; Rotchell, Jeanette M.; Nahrgang, Jasmine (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-27)
    Studies that aim to characterise the susceptibility of the ecologically relevant and non-model fish polar cod (Boreogadus saida) to model carcinogens are required. Polar cod were exposed under laboratory conditions for six months to control, 0.03 μg BaP/g fish/week and 0.3 μg BaP/g fish/week dietary benzo(a)pyrene (BaP), a reference carcinogen. The concentrations of the 3-OH-BaP bile metabolite and ...
  • Variable responses of carbon and nitrogen contents in vegetation and soil to herbivory and warming in high-Arctic tundra 

    Petit Bon, Matteo; Bøhner, Hanna; Bråthen, Kari Anne; Ravolainen, Virve; Jónsdóttir, Ingibjörg Svala (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-21)
    Chemical responses of tundra vegetation and tundra soil to environmental changes are likely to differ, with implications for ecosystem functioning, yet they are rarely compared. Here, we aimed at comparing sensitivity and magnitude of short-term carbon and nitrogen responses of three main tundra ecosystem compartments: vascular plants, mosses, and soil, to two environmental perturbations: herbivore ...
  • Powder Fever and Its Impact on Decision-Making in Avalanche Terrain 

    Mannberg, Andrea; Hetland, Audun; Hendrikx, Jordy; Johnson, Jerry (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-09)
    We examined the effect of emotions, associated with “powder fever”, on decision-making in avalanche terrain. Background: Skiing in avalanche terrain is a voluntary activity that exposes the participant to potentially fatal risk. Impaired decision-making in this context can therefore have devastating results, often with limited prior corrective feedback and learning opportunities. Previous research ...
  • Cannibalism and protective behavior of eggs in Arctic charr (Salvelinus alpinus) 

    Frye, Marilena; Egeland, Torvald Blikra; Nordeide, Jarle Tryti; Folstad, Ivar (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-28)
    From video recordings of spawning events, we quantified protective and cannibalistic behavior of Arctic charr occurring immediately after spawning. The number of fish cannibalizing on stray eggs was examined regarding (a) whether more than one male shed milt during the spawning event, that is, whether sperm competition occurred, (b) whether the sperm competition included few or many males, that is, ...
  • Microbial carbon use and associated changes in microbial community structure in high-Arctic tundra soils under elevated temperature 

    Frossard, Aline; De Maeyer, Lotte; Adamczyk, Magdalene; Svenning, Mette Marianne; Verleyen, Elie; Frey, Beat (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-08)
    In the high-Arctic, increased temperature results in permafrost thawing and increased primary production. This fresh plant-derived material is predicted to prime microbial consortia for degradation of the organic matter stored in tundra soils. However, the effects of warming and plant input on the microbial community structure is hardly known. We assessed the use of glycine, a readily available C ...
  • Influence of reproductive output on divorce rates in polar seabirds 

    Mercier, Guillaume; Yoccoz, Nigel; Descamps, Sébastien (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-15)
    The high occurrence of social monogamy in birds has led to questions about partner fidelity, or the perennial nature of monogamy from one breeding season to another. Despite the evolutionary advantages of partner fidelity, divorce occurs among 95% of bird species. We aimed to describe patterns of divorce and partner fidelity in five seabird species breeding in Arctic and Antarctic regions and ...
