    The increasing human demand for high-quality animal protein has provided impetus for the development of aquaculture. Chinese mitten crab (Eriocheir sinensis) is a catadromous species rapidly being cultured in China but scientific literature documenting its life cycle environmental and economic consequences remains scarce. This study aims to address this gap by examining the spatio-temporal evolution ...
  • The Image Fallacy: Rethinking the Tragedy of the Commons 

    Jentoft, Svein (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-05)
    An image is what we have in our head and what we make up in an allegory, a name, a metaphor, a text, a map or in a drawing. None of these should be confused with the thing that is being imagined. They are not the real thing, just our imaginations of it. Still, we could not do without them, for instance when governing small-scale fisheries. They make us understand what we are up to and the track we ...

  • Adjusting the Fitting of Fluorescence-Based Dose-Response Kinase Inhibition Assay to Account for Fluorescent Inhibitors 

    Petit, Guillaume Axel (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-11)
    Fluorescence is routinely used to monitor kinase inhibition in commercial assays. Occasionally fluorescent compounds can interfere with the fluorescent reading. To address this issue, the problematic data are usually truncated to improve the fit, however, this approach raises ethical and reproducibility concerns. Instead, it is suggested to adjust the fitting formula, to account for the autofluorescence ...
  • Marine heatwaves are not a dominant driver of change in demersal fishes 

    Fredston, Alexa L.; Cheung, William W. L.; Frölicher, Thomas L.; Kitchel, Zoë J.; Maureaud, Aurore A.; Thorson, James T.; Auber, Arnaud; Mérigot, Bastien; Palacios-Abrantes, Juliano; Palomares, Maria Lourdes D.; Pecuchet, Laurene Anne Marie; Shackell, Nancy L.; Pinsky, Malin L. (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-08-30)
    Marine heatwaves have been linked to negative ecological effects in recent decades1,2. If marine heatwaves regularly induce community reorganization and biomass collapses in fishes, the consequences could be catastrophic for ecosystems, fisheries and human communities3,4. However, the extent to which marine heatwaves have negative impacts on fish biomass or community composition, or even whether ...

    Despite great promise for understanding the impacts and extent of climate change on aquatic animals, their species, and ecological communities, it is surprising that tracking tools, like biotelemetry and biologging devices, have not been extensively used to understand climate change or develop and evaluate potential interventions that may forestall or mitigate its effects. In this review, we provide ...
  • From propriety to validity in new ventures: A nine-year study of three startup companies 

    Oftedal, Elin Merethe; Foss, Lene; Rutherford, Matthew (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-01-10)
    New ventures introducing new technological innovations must, to survive, negotiate legitimacy with stakeholders who provide critical resources (e.g., Zimmerman and Zeitz, 2002). Legitimacy - “a generalized perception or assumption that the actions of an entity are desirable, proper, or appropriate within some socially constructed system of norms, values, beliefs, and definitions” (Suchman, 1995, p. ...
  • Growth strategies of Chlorella vulgaris in seawater for a high production of biomass and lipids suitable for biodiesel 

    Rautenberger, Ralf; Detain, Alexandre; Skjånes, Kari; Schulze, Peter Simon Claus; Kiron, Viswanath; Morales Sanchez, Daniela (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-12-09)
    Chlorella vulgaris is a freshwater microalga that synthesises large amounts of saturated lipids, which makes it suitable for production of bioenergy and biofuels. Since its cultivation usually requires freshwater, it competes with agriculture, economic development and ecological conservation for this limited natural resource. This study investigated the possibility of the partial replacement of ...
  • Revealing the Host-Dependent Nature of an Engineered Genetic Inverter in Concordance with Physiology 

    Chan, Dennis Tin Chat; Bernstein, Hans Christopher; Baldwin, Geoff S. (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-08-16)
    Broad-host-range synthetic biology is an emerging frontier that aims to expand our current engineerable domain of microbial hosts for biodesign applications. As more novel species are brought to “model status,” synthetic biologists are discovering that identically engineered genetic circuits can exhibit different performances depending on the organism it operates within, an observation referred ...
