• Ecosystem model for evaluating potential cod production in a west Norwegian fjord 

      Salvanes, Anne Gro Vea; Aksnes, Dag Lorents; Giske, Jarl (Peer reviewed; Journal article, 1992-12-08)
      The carrying capacity for cod in a Norwegian fjord was analysed by means of a simulation model. Four age groups of cod were represented as well as the maln prey groups labrids, gobies and benthic organisms. These groups ...
    • The emotion system promotes diversity and evolvability 

      Giske, Jarl; Eliassen, Sigrunn; Fiksen, Øyvind; Jakobsen, Per Johan; Aksnes, Dag Lorents; Mangel, Marc; Jørgensen, Christian (Peer reviewed; Journal article, 2014-08-06)
      Studies on the relationship between the optimal phenotype and its environment have had limited focus on genotype-to-phenotype pathways and their evolutionary consequences. Here, we study how multi-layered trait architecture ...
    • From sensing to emergent adaptations: Modelling the proximate architecture for decision-making 

      Eliassen, Sigrunn; Andersen, Bjørn Snorre; Jørgensen, Christian; Giske, Jarl (Peer reviewed; Journal article, 2016-04)
      During the past 50 years, evolutionary theory for animal behaviour has branched into different methodological frameworks focussing on age-, state-, density-, and frequency-dependent processes. These approaches have led to ...
    • The global potential for carbon capture and storage from forestry 

      Ni, Yuanming; Eskeland, Gunnar; Giske, Jarl; Hansen, Jan Petter (Peer reviewed; Journal article, 2016-02-26)
      Background: Discussions about limiting anthropogenic emissions of CO2 often focus on transition to renewable energy sources and on carbon capture and storage (CCS) of CO2. The potential contributions from forests, forest ...
    • Hormones as adaptive control systems in juvenile fish 

      Weidner, Jacqueline; Jensen, Camilla Håkonsrud; Giske, Jarl; Eliassen, Sigrunn; Jørgensen, Christian (Peer reviewed; Journal article, 2020-02-17)
      Growth is an important theme in biology. Physiologists often relate growth rates to hormonal control of essential processes. Ecologists often study growth as a function of gradients or combinations of environmental factors. ...
    • Impact of hatch-date on early life growth and survival of Mueller's pearlside (Maurolicus Muelleri) larvae, and life-history consequences 

      Folkvord, Arild; Gundersen, Geir; Albretsen, Jon; Asplin, Lars; Kaartvedt, Stein; Giske, Jarl (Peer reviewed; Journal article, 2016-02)
      Growth and survival of Maurolicus muelleri larvae in Herdlefjorden, Norway, were investigated by daily otolith increment analysis. While high egg densities were generally observed throughout the spawning season, three ...
    • Making predictions in a changing world: The benefits of individual-based ecology 

      Stillman, Richard A.; Railsback, Steven F.; Giske, Jarl; Berger, Uta; Grimm, Volker (Peer reviewed; Journal article, 2015-12-17)
      Ecologists urgently need a better ability to predict how environmental change affects biodiversity. We examine individual-based ecology (IBE), a research paradigm that promises better a predictive ability by using ...
    • Optimal defense strategies in an idealized microbial food web under trade-off between competition and defense 

      Våge, Selina; Storesund, Julia Endresen; Giske, Jarl; Thingstad, Tron Frede (Peer reviewed; Journal article, 2014-07-07)
      Trophic mechanisms that can generate biodiversity in food webs include bottom-up (growth rate regulating) and top-down (biomass regulating) factors. The top-down control has traditionally been analyzed using the concepts ...
    • The proximate architecture for decision-making in fish 

      Andersen, Bjørn Snorre; Jørgensen, Christian; Eliassen, Sigrunn; Giske, Jarl (Peer reviewed; Journal article, 2016-09)
      Evolution has since the very beginning resulted in organisms which can sort fitness-related information from noise, evaluate it and respond to it. In animals, the architecture for proximate control of behaviour and physiology ...
    • Vertical distribution and trophic interactions of zooplankton and fish in Masfjorden, Norway 

      Giske, Jarl; Aksnes, Dag Lorents; Balino, Beatriz M.; Kaartvedt, Stein; Lie, Ulf; Nordeide, Jarle Tryti; Salvanes, Anne Gro Vea; Wakili, Sami M.; Aadnesen, Agnes (Peer reviewed; Journal article, 1990)
      The distribution, biomass, and predator-prey relationships of the pelagic assemblage in Masfjorden, western Norway, was studied in January 1989. The pelagic biomass was dominated by particulate organic matter. Biomasses ...
