      Zhang, Dengjun; Xie, Jinghua (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-11-07)
      Electricity distribution operators are regulated as monopolies around the world. Incentive regulation is further applied to relate their allowed revenues (revenue cap) to cost efficiency and investment. Incentive regulation varies cross countries and has evolved over time for individual countries. Norway is one of the first countries reforming the network distributors by incentive regulation. Using ...

    • Climate-driven changes in functional biogeography of Arctic marine fish communities 

      Frainer, André; Primicerio, Raul; Kortsch, Susanne; Aune, Magnus; Dolgov, Andrey V.; Fossheim, Maria; Aschan, Michaela (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-11-14)
      Climate change triggers poleward shifts in species distribution leading to changes in biogeography. In the marine environment, fish respond quickly to warming, causing community-wide reorganizations, which result in profound changes in ecosystem functioning. Functional biogeography provides a framework to address how ecosystem functioning may be affected by climate change over large spatial ...

    • When things go wrong: intra-season dynamics of breeding failure in a seabird 

      Ponchon, Aurore; Grémillet, David J.H.; Christensen-Dalsgaard, Signe; Erikstad, Kjell E; Barrett, Robert T.; Reiertsen, Tone Kristin; McCoy, Karen D.; Tveraa, Torkild; Boulinier, Thierry (Journal article; Tidsskriftartikkel; Peer reviewed, 2014-01-16)
      During breeding, long-lived species face important time and energy constraints that can lead to breeding failure when food becomes scarce. Despite the potential implications of intra-season dynamics in breeding failure for individual behavior, carry-over effects, dispersal decisions and population dynamics, little information is currently available on these dynamics at fine temporal scales. Here, ...

    • Drivers for compliance with fisheries rules. A systematic literature review 

      Tuktarov, Boris (Master thesis; Mastergradsoppgave, 2016-11-17)
      Many diverse conflicts are commonly found in a complex and dynamic system such as a fishery. Usual sources of conflicts are property rights conflicts, space utilization conflicts (e.g. fishers versus aquaculture), enforcement conflicts and conflicts that occur between the fishers and the government. The latter two may lead to issues with fisher’s compliance with state laws. This thesis examines ...

    • Comparison of individual transferable quota in New Zealand and individual vessel quota in Norway 

      Mikhnyuk, Elizaveta (Master thesis; Mastergradsoppgave, 2016-11-21)
      Since the introduction of licenses and quotas as important management instruments, Norway has established a system of non-transferable IVQs. The “cod-crisis” was a reason for the Nor- wegian Parliament to reject an ITQ system with a high degree of transactions. However, since the late 80s the IVQ regime have forced towards a market-oriented regime for the expansion of the transferability. The overall ...

    • Regulation of gene expression is associated with tolerance of the Arctic copepod Calanus glacialis to CO2-acidified sea water 

      Bailey, Allison Michelle; De Wit, Pierre; Thor, Peter; Browman, Howard; Bjelland, Reidun Marie; Shema, Steven; Fields, David M.; Runge, Jeffrey A.; Thompson, Cameron; Hop, Haakon (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-08-02)
      Ocean acidification is the increase in seawater pCO2 due to the uptake of atmospheric anthropogenic CO2, with the largest changes predicted to occur in the Arctic seas. For some marine organisms, this change in pCO2, and associated decrease in pH, represents a climate change-related stressor. In this study, we investigated the gene expression patterns of nauplii of the Arctic copepod Calanus glacialis ...

    • An Analysis of a Semelparous Population Model with Density-Dependent Fecundity and Density - Dependent Survival Probabilities. 

      Wikan, Arild (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-12-17)
      A discrete age-structured semelparous Leslie matrix model where density dependence is included both in the fecundity and in the survival probabilities is analysed. Depending on strength of density dependence, we show in the precocious semelparous case that the nonstationary dynamics may indeed be rich, ranging from SYC (a dynamical state where the whole population is in one age class only) dynamics ...
