    Several shrimp trawl fisheries use a Nordmöre sorting grid to avoid bycatch of fish. However, small fish can pass through the grid. Therefore, the retention of juvenile fish often remains an issue during shrimp trawling. We investigated the vertical distribution of deepwater shrimp (<i>Pandalus borealis</i>) and dominant bycatch species at the point where the Nordmöre grid section is installed. This ...

    Lima, Serena; Schulze, Peter Simon Claus; Schüler, Lisa M.; Rautenberger, Ralf; Morales-Sanchez, Daniela; Santos, Tamára F.; Pereira, Hugo; Varela, João C.S.; Scargiali, Francesca; Wijffels, Rene Hubertus; Kiron, Viswanath (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-25)
    As the periodic emission of light pulses by light emitting diodes (LEDs) is known to stimulate growth or induce high value biocompounds in microalgae, this flashing light regime was tested on growth and biochemical composition of the microalgae <i>Nannochloropsis gaditana, Koliella antarctica</i> and <i>Tetraselmis chui</i>. At low flashing light frequencies (e.g., 5 and 50 Hz, Duty cycle = 0.05), ...
  • Hav, fisk og ressursforvaltning i nordområdene 

    Hoel, Alf Håkon (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-12-08)
    Mesteparten av norske havområder ligger nord for polarsirkelen og er åsted for noen av verdens rikeste fiskerier. De største fiskebestandene er delt med andre land, og internasjonalt samarbeid om ressursforvaltningen er derfor en viktig dimensjon ved nordområdepolitikken. Slikt samarbeid er basert på globale normer om hvordan levende marine ressurser skal forvaltes og deles og foregår på en rekke ...
  • Ecological speciation in European whitefish is driven by a large‐gaped predator 

    Öhlund, Gunnar; Bodin, Mats; Nilsson, Karin; Öhlund, Sven-Ola; Mobley, Kenyon B.; Hudson, Alan G.; Peedu, Mikael; Brännström, Åke; Bartels, Pia; Præbel, Kim; Hein, Catherine L.; Johansson, Petter; Englund, Göran (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-05-13)
    Lake‐dwelling fish that form species pairs/flocks characterized by body size divergence are important model systems for speciation research. Although several sources of divergent selection have been identified in these systems, their importance for driving the speciation process remains elusive. A major problem is that in retrospect, we cannot distinguish selection pressures that initiated divergence ...

  • The Transformation of Extralegal Principles into Legal Principles by the International Court of Justice in The Hague: Illustrated by a Peaceful Delimitation of «the Promised Land» 

    Ørebech, Peter Th (Journal article; Tidsskriftartikkel; Peer reviewed, 2020)
    Social norms are mixtures of extralegal and legal principles. The International Court of Justice‟ in The Hague‟s (ICJ) adjudication subtracts normative structures from different sources, moral, ethical, religious etc. dogmas amplifying its case law. The failing Israel-Palestine reconciliation that results from “power asymmetries” and “supreme emergency exception”, illustrates how absence of concomitant ...
  • Infection and microbial molecular motifs modulate transcription of the interferon-inducible gene ifit5 in a teleost fish 

    Bela-Ong, Dennis; Greiner-Tollersrud, Linn; van der Wal, Yorick Andreas; Jensen, Ingvill; Seternes, Ole Morten; Jørgensen, Jorunn (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-05-21)
    Interferon-induced proteins with tetratricopeptide repeats (IFITs) are involved in antiviral defense. Members of this protein family contain distinctive multiple structural motifs comprising tetratricopeptides that are tandemly arrayed or dispersed along the polypeptide. IFIT-encoding genes are upregulated by type I interferons (IFNs) and other stimuli. IFIT proteins inhibit virus replication by ...

    The spatial extent and persistence of bacterial change caused by deposition of water-based drill cuttings on the seafloor were explored by a community-wide approach. Ten centimeter sediment cores were sampled along transects extending from ≤15 m to 250 m from three nearby drilling sites in the southern Barents Sea. Eight months, 8 years and 15 years, respectively, had passed since the completion of ...
  • Fine-Tuning Climate Resilience in Marine Socio-Ecological Systems: The Need for Accurate Space-Time Representativeness to Identify Relevant Consequences and Responses 

    Saldívar-Lucio, Romeo; Trasviña-Castro, Armando; Jiddawi, Narriman; Chuenpagdee, Ratana; Lindström, Lars; Jentoft, Svein; Fraga, Julia; de la Torre-Castro, Maricela (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-18)
    Climate change triggers a wide mosaic of regional and local responses, often different to the large-scale variability in magnitude and direction. Because of the psychological connections (cognitive and emotional) with the frequency, intensity and age of a climatic event, people may have the capacity to recognize key variations at lower scales, especially those from which they perceive risk. Yet, the ...
