  • Allochrony as a potential driver for reproductive isolation in adaptive radiations of European whitefish ecomorphs 

    Bitz-Thorsen, Julie; Häkli, Katja; Bhat, Shripathi; Præbel, Kim (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-29)
    In northern Fennoscandian lakes, monophylogenetic lineages of postglacial fishes are radiating into several adaptive forms, but the speciation process is still at an incipient stage. The speciation process has received increased attention over the years, but the underlying mechanisms and drivers are still debated and poorly understood. European whitefish (<i>Coregonus lavaretus</i> [L.]) is the most ...

    <ol> <li>Metabarcoding extra‐organismal DNA from environmental samples is now a key technique in aquatic biomonitoring and ecosystem health assessment. Of critical consideration when designing experiments, and especially so when developing community standards and legislative frameworks, is the choice of genetic marker and primer set. Mitochondrial cytochrome c oxidase subunit I (COI), the standard ...
  • Environmental DNA metabarcoding as an effective and rapid tool for fish monitoring in canals 

    McDevitt, Allan D; Sales, Naiara Guimaraes; Browett, Samuel S.; Sparnenn, Abbie O.; Mariani, Stefano; Wangensteen Fuentes, Owen Simon; Coscia, Ilaria; Benvenuto, Chiara (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-06-10)
    We focus on a case study along an English canal comparing environmental DNA (eDNA) metabarcoding with two types of electrofishing techniques (wade‐and‐reach and boom‐boat). In addition to corroborating data obtained by electrofishing, eDNA provided a wider snapshot of fish assemblages. Given the semi‐lotic nature of canals, we encourage the use of eDNA as a fast and cost‐effective tool to detect and ...

    Sales, Naiara Guimaraes; Wangensteen Fuentes, Owen Simon; Carvalho, Daniel C.; Mariani, Stefano (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-05-31)
    Environmental DNA (eDNA) has rapidly emerged as a promising biodiversity monitoring technique, proving to be a sensitive and cost‐effective method for species detection. Despite the increasing popularity of eDNA, several questions regarding its limitations remain to be addressed. We investigated the effect of sampling medium and time, and preservation methods, on fish detection performance based on ...
  • Forfeiting the priority effect: turnover defines biofilm community succession 

    Brislawn, Colin J.; Graham, Emily B.; Dana, Karl; Ihardt, Peter; Fansler, Sarah J.; Chrisler, William B.; Cliff, John B.; Stegen, James C.; Moran, James J.; Bernstein, Hans C. (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-03-18)
    Microbial community succession is a fundamental process that affects underlying functions of almost all ecosystems; yet the roles and fates of the most abundant colonizers are often poorly understood. Does early abundance spur long term persistence? How do deterministic and stochastic processes influence the ecological contribution of colonizers? We performed a succession experiment within a hypersaline ...
  • Peracetic acid as a potential treatment for amoebic gill disease (AGD) in Atlantic salmon - Stage 1 

    Lazado, Carlo C.; Timmerhaus, Gerrit; Pedersen, Lars-Flemming; Pittman, Karin; Soleng, Malene; Haddeland, Sindre; Johansen, Lill-Heidi; Breiland, Mette Serine Wesmajervi; Rørmark, Lisbeth; Mohammad, Saima; Hytterød, Sigurd (Research report; Forskningsrapport, 2019-06)
    PERAGILL is an initiative that ultimately aims to develop an alternative treatment for the currently available therapies for amoebic gill disease (AGD) that have several practical and environmental issues. Peracetic acid (PAA) is a potent oxidant with a broad spectrum of antimicrobial activity and decays into relatively safe residuals, thus, has been widely recognised as a sustainable disinfectant ...
  • The regulative lock-in: the challenge of establishing Sami fisheries governance in Norway 

    Johnsen, Jahn Petter; Søreng, Siri Ulfsdatter (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-06)
    For almost 30 years, the Sami Parliament has worked to gain influence in the Norwegian fisheries governing system in order to secure Sami fisheries as the material basis of Sami culture. Due to developments in international law and their implementation in state law, the Sami Parliament has gained formal access to the country’s fisheries governance decision-making process. This paper addresses the ...

    Penaranda, Ma Michelle Demogina; Jensen, Ingvill; Tollersrud, Linn G.; Bruun, Jack-Ansgar; Jørgensen, Jorunn B. (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-01-29)
    Fish immunology research is at a pivotal point with the increasing availability of functional immunoassays and major advances in <i>omics</i> approaches. However, studies on fish B cells and their distinct subsets remain a challenge due to the limited availability of differentially expressed surface markers. To address this constraint, cell surface proteome of Atlantic salmon IgM<sup>+</sup> B cells ...
  • Microbial danger signals control transcriptional induction of distinct MHC class I L lineage genes in Atlantic salmon 

    Svenning, Steingrim; Gondek-Wyrozemska, Agata T; van der Wal, Yorick Andreas; Robertsen, Børre; Jensen, Ingvill; Jørgensen, Jorunn B; Edholm, Eva-Stina Isabella (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-10-11)
    Antigen processing and presentation by major histocompatibility complex (MHC) molecules is a cornerstone in vertebrate immunity. Like mammals, teleosts possess both classical MHC class I and multiple families of divergent MHC class I genes. However, while certain mammalian MHC class I-like molecules have proven to be integral in immune regulation against a broad array of pathogens, the biological ...
  • The Neglected Marine Fungi, Sensu stricto, and Their Isolation for Natural Products’ Discovery 

    Overy, David P.; Rämä, Teppo; Oosterhuis, Rylee; Walker, Allison K.; Pang, Ka-Lai (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-01-10)
    Despite the rapid development of molecular techniques relevant for natural product research, culture isolates remain the primary source from which natural products chemists discover and obtain new molecules from microbial sources. Techniques for obtaining and identifying microbial isolates (such as filamentous fungi) are thus of crucial importance for a successful natural products’ discovery program. ...
  • Quantification of bell-shaped size selectivity in shrimp trawl fisheries using square mesh panels and a sorting cone after a Nordmøre grid 

    Sistiaga, Manu Berrondo; Herrmann, Bent; Larsen, Roger B.; Brinkhof, Jesse (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-09-12)
    Shrimp trawlers in the Barents Sea use a Nordmøre sorting grid ahead of a small-mesh codend to avoid bycatch while catching shrimps efficiently. However, small fish can still pass through the grid to enter the codend, which increases their risk of being retained. In this study, we quantified the selectivity of a standard Nordmøre grid used together with one of two different codend designs, namely a ...
  • Trained Innate Immunity of Fish Is a Viable Approach in Larval Aquaculture 

    Zhang, Zuobing; Chi, Heng; Dalmo, Roy Ambli (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-01-25)
    The general understanding has been that only adaptive immunity is capable of immunological memory, but this concept has been challenged in recent years by studies showing that innate immune systems can mount resistance to reinfection—as the innate immune system can adapt its function following an insult. Innate immune training offers an attractive approach in intensive fish larval rearing, especially ...
  • Persistence of environmental DNA in marine systems 

    Collins, Rupert A.; Wangensteen Fuentes, Owen Simon; O'Gorman, Eoin J.; Mariani, Stefano; Sims, David W.; Genner, Martin J. (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-05)
    As environmental DNA (eDNA) becomes an increasingly valuable resource for marine ecosystem monitoring, understanding variation in its persistence across contrasting environments is critical. Here, we quantify the breakdown of macrobial eDNA over a spatio-temporal axis of locally extreme conditions, varying from ocean-influenced offshore to urban-inshore, and between winter and summer. We report that ...

    Edwards, Jena E.; Hiltz, Elizabeth; Broell, Franziska; Bushnell, Peter G.; Campana, Steven E.; Christiansen, Jørgen Schou; Devine, Brynn M.; Gallant, Jeffrey J.; Hedges, Kevin J.; MacNeil, M. Aaron; McMeans, Bailey C.; Nielsen, Julius; Præbel, Kim; Skomal, Gregory B.; Steffensen, John Fleng; Walter, Ryan P.; Watanabe, Yuuki Y.; VanderZwaag, David L.; Hussey, Nigel E. (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-02)
    Long-lived species share life history traits such as slow growth, late maturity, and low fecundity, which lead to slow recovery rates and increase a population’s vulnerability to disturbance. The Greenland shark (Somniosus microcephalus) has recently been recognized as the world’s longest-lived vertebrate, but many questions regarding its biology, physiology, and ecology remain unanswered. Here we ...
  • Ranking of substances for monitoring in foods, drinks and dietary supplements - based on risk and knowledge gaps
