      Töpper, Birte (The University of Bergen, 2012-06-29)
      The Arctic Ocean is a unique marine environment with respect to irradiation periodicity and intensity, temperature, ice formation and strong stratification. Changes due to global warming might be more pronounced in this ...

    • Bacterial growth control in marine environments : from experimental approaches to comparative analyses 

      Cuevas, Luis Antonio (The University of Bergen, 2010-12-14)
      To understand (1) the role of heterotrophic bacteria in the biogeochemical cycles, (2) the fate of the organic carbon and mineral nutrients, and (3) the flow of energy to higher trophic levels, we need to understand how ...

    • Bacterial growth response to copepod grazing in aquatic ecosystems 

      Vargas, Cristian A.; Cuevas, Luis Antonio; González, Humberto E.; Daneri, Giovanni (Cambridge University Press, 2007)
      The growth rate response of bacterial communities to the potential increase of dissolved organic matter (DOM) produced by the copepod Acartia tonsa was assessed in experiments conducted in three stations representing ...

    • Bacterial Response to Permafrost Derived Organic Matter Input in an Arctic Fjord 

      Müller, Oliver; Seuthe, Lena; Bratbak, Gunnar; Paulsen, Maria Lund (Frontiers, 2018-08-06)
      The warming of the Arctic causes increased riverine discharge, coastal erosion, and the thawing of permafrost. Together, this is leading to an increased wash out of terrestrial dissolved organic matter (tDOM) into the ...

    • Balanced harvest: Utopia, failure, or a functional strategy? 

      Kolding, Jeppe; Garcia, Serge M.; Zhou, Shijie; Heino, Mikko Petteri (Oxford University Press, 2016-04-21)
      Since “balanced harvest” was proposed in 2010 as a possible tool in the operationalization of the ecosystem approach to fisheries (EAF), the concept gained extensive international attention. Because maintaining ecosystem ...

    • Ballan wrasse (Labrus bergylta) predation on hatchery reared scallop (Pecten maximus) spat 

      Oppegård, Guri Gunnes (The University of Bergen, 2005)
      Sea ranching of the great scallop (Pecten maximus) may have a high potential for future aquaculture in Norway. The edible crab (Cancer pagurus) and starfish (Asterias rubens) have been identified as the major predators, ...

    • Barents Sea capelin and us; Do they really mature and migrate at 14cm? Or have we become prisoners in our own Platonic allegory? How shall we respond? 

      Seal, Henry (The University of Bergen, 2018-06-15)
      Capelin (Mallotus Villosus) are an important component of the Barents Sea ecosystem. As zooplankton consumers they play a role in channelling energy up the food web, and they have the potential to represent a biomass of ...
