      Carranza, Alvar; Agudo-padrón, Ignacio; Collado, Gonzalo A.; Damborenea, Cristina; Fabres, Alejandra a.; Gutiérrez Gregoric, Diego E.; Lodeiros, César; Ludwig, Sandra; Pastorino, Guido; Penchaszadeh, Pablo E.; Salvador, Rodrigo Brincalepe; Spotorno, Paula; Thiengo, Silvana C.; Vidigal, Teofânia; Darrigran, Gustavo (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-02-15)
      The impacts of biological invasions remain poorly known for some habitats, regions and taxa. To date, there has been no comprehensive effort to review and synthesize the impacts of invasive mollusc species in South America. In this paper, we provide a synoptic view on what is known on documented socio-ecological impacts of aquatic no-native mollusc species (NNMS) and transplanted mollusc species ...
    • Motivation for learning statistics: An example from fishery and aquaculture science 

      Sønvisen, Signe Annie (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-04-15)
      Teaching statistics to generalist students oriented toward a profession, rather than academic merits, may be challenging. As statistics courses also tend to have a low student appeal, tailoring a course toward this type of audience is demanding. Framed within the theory of statistical thinking and literacy, this article shows how an investigative process, using domain data and real-life examples, ...

      Humans have a motivational system that influences cognition and behavior to minimize the risk of contact with pathogens. This research examines the relationship between cyberspace disease salience and mobility behavior at the macro and micro levels. Across two studies, we predict and find that people adjust their mobility behavior to minimize the risk of close physical contact with strangers ...
    • Four new suomilides isolated from the cyanobacterium Nostoc sp. KVJ20 and proposal of their biosynthetic origin 

      Schneider, Yannik Karl Heinz; Liaimer, Anton; Isaksson, Johan Mattias; Wilhelmsen, Oda Sofie Bye; Andersen, Jeanette Hammer; Østnes Hansen, Kine; Hansen, Espen Holst (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-04-20)
      The suomilide and the banyasides are highly modified and functionalized non-ribosomal peptides produced by cyanobacteria of the order Nostocales. These compound classes share several substructures, including a complex azabicyclononane core, which was previously assumed to be derived from the amino acid tyrosine. In our study we were able to isolate and determine the structures of four suomilides, ...
    • Consumers’ values, attitudes and behaviours towards consuming seaweed food products: The effects of perceived naturalness, uniqueness, and behavioural control 

      Govaerts, Florent; Olsen, Svein Ottar (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-12-27)
      Seaweed has great potential as a natural, healthy, and sustainable food. Seaweed as food is novel in Western countries; thus, few studies have focused on the factors influencing consumers’ behavioural tendencies towards seaweed food products. This study aimed to fill the gap by investigating the antecedents for consumers’ attitudes towards as well as their consumption of seaweed food products in a ...

      Fernández-Míguez, Maria; Puvanendran, Velmurugu; Burgerhout, Erik; Presa, Pablo; Tveiten, Helge; Vorkamp, Katrin; Hansen, Øyvind J; Johansson, Gunhild Seljehaug; Bogevik, André Sture (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-09)
      Microplastics (MPs) have become a global issue as they are omnipresent in the ocean. Fish ingesting MPs through feed could be affected in their physiological function, e.g., disrupted enzyme production and function, reduction of feeding and reproductive failure. This study assessed the effects of feed containing naturally weathered MPs from the Oslofjord (Norway) on the reproductive physiology of ...
    • Spatiotemporal distribution and co-occurrence of Arctic herbivores in spring 

      Grimsby, Anna Caroline (Master thesis; Mastergradsoppgave, 2022-04-19)
      Biotic interactions play an important role in the structure and dynamics of food-webs and may drive the spatial distribution of species. In the Arctic, spring snow-cover limits the availability of resources at a critical time for resident and migratory herbivores, which could lead to resource competition. This study takes a first step towards understanding the potential for competition between the ...
    • Is capture-based aquaculture viable? The case of Atlantic cod in Norway 

      Pettersen, Ingrid Kristine; Asche, Frank; Bronnmann, Julia; Sogn-Grundvåg, Geir; Straume, Hans-Martin (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-25)
      Capture-based aquaculture (CBA) is an important branch of the aquaculture industry that differs from closed cycle farming in that the stocking material consists of captured wild fish or other aquatic organisms. By skipping the difficult early production stages of fish farming, producers can test whether assumed market advantages such as high quality and consistent supply result in higher prices – ...

    • Establishment of killer whale (Orcinus orca) primary fibroblast cell cultures and their transcriptomic responses to pollutant exposure 

      Bjørneset, Juni; Blévin, Pierre; Bjørnstad, Pål Marius; Dalmo, Roy Ambli; Goksøyr, Anders; Harju, Mikael; Yadetie, Fekadu; Routti, Heli Anna Irmeli; Limonta, G.; Panti, C.; Sundaram, A.Y.M.; Rikardsen, Audun H. (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-04-02)
      Populations of killer whale (Orcinus orca) contain some of the most polluted animals on Earth. Yet, the knowledge on effects of chemical pollutants is limited in this species. Cell cultures and in vitro exposure experiments are pertinent tools to study effects of pollutants in free-ranging marine mammals. To investigate transcriptional responses to pollutants in killer whale cells, we collected skin ...
    • Appropriation of economic values in a rights-based fishery 

      Bertheussen, Bernt Arne; Vassdal, Terje (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-02-21)
      This study integrates resource-based and stakeholder theories to explore how values are generated and appropriated in a rights-based fishery. We argue that in the fish harvesting industry, a firm’s ability to create values is critically dependent on stakeholders outside the firm’s boundaries, such as society in general (the principal owner of the natural resource) and the fisheries management of ...
