    • Robuste sjømatinntekter også under COVID-19 pandemien 

      Bertheussen, Bernt Arne (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-05-09)
      Norge er verdens nest største eksportør av sjømat. Inntektene skaper arbeid og aktivitet i lokalsamfunn langs hele kysten. Denne studien undersøker hvor sårbare inntektene til sjømatnæringen har vært under Covid-19 pandemien som har preget mesteparten av 2020 og hele 2021. I tillegg til å analysere inntektsutviklingen på aggregert nivå for fiskeri og havbruk, presenterer studien sektorvise analyser ...
    • Rodent population cycle as a determinant of gastrointestinal nematode abundance in a low-arctic population of the red fox 

      Mørk, Torill; Ims, Rolf Anker; Killengreen, Siw Turid (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-03-22)
      We analyzed an 11-year time series (2005–2015) of parasite abundance for three intestinal nematode species in the red fox (<i>Vulpes vulpes</i>) as a function of the multi-annual rodent population cycle in low-arctic Norway, while correcting for other potential covariates that could influence prevalence and abundance. Rodents are paratenic and facultative intermediate hosts for the two Ascarididae ...
    • Rodinia to Gondwana evolution record, South Sinai, Egypt: Geological and geochronological constraints 

      Anbar, Mohamed Abu; Abu Alam, Tamer Sabry Zaki; Ghoneim, Mohamed F.; Dong, YunPeng; Li, Xian-Hua; Ramadan, Dina H.; Masoud, Ahmed E. (Journal article; Tidsskriftartikkel, 2023-11-02)
      The geological history of Sinai is complicated and differs from the other parts of the Arabian Nubian Shield. Some rocks in Sinai have a signature from the Grenvillian crust, as evidenced in Wadi Seih area. The ultimate objective of this research is to clarify the progression of episodic island arc accretion events from the amalgamation of Rodinia to the assembly of Gondwana supercontinent.Geochemical, ...
    • Role for Atlantic inflows and sea ice loss on shifting phytoplankton blooms in the Barents Sea 

      Oziel, L; Neukermans, G; Ardyna, M; Lancelot, C; Tison, J-L; Wassmann, Paul; Sirven, J; Ruiz-Pino, D; Gascard, J-C (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-05-16)
      Phytoplankton blooms in the Barents Sea are highly sensitive to seasonal and interannual changes in sea ice extent, water mass distribution, and oceanic fronts. With the ongoing increase of Atlantic Water inflows, we expect an impact on these blooms. Here, we use a state‐of‐the‐art collection of in situ hydrogeochemical data for the period 1998–2014, which includes ocean color satellite‐derived ...
    • The role of a dominant predator in shaping biodiversity over space and time in a marine ecosystem 

      Ellingsen, Kari Elsa; Anderson, Marti J.; Shackell, Nancy L.; Tveraa, Torkild; Yoccoz, Nigel Gilles; Frank, Kenneth T. (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-06-24)
      Exploitation of living marine resources has resulted in major changes to populations of targeted species and functional groups of large-bodied species in the ocean. However, the effects of overfishing and collapse of large top predators on the broad-scale biodiversity of oceanic ecosystems remain largely unexplored. Populations of the Atlantic cod (Gadus morhua) were overfished and several collapsed ...
    • The role of attitude, preference conflict, norms, and family identity in explaining intention/behavior toward fish consumption in Vietnamese families 

      Le, Chi Cong (Master thesis; Mastergradsoppgave, 2010-05-16)
      The main objective of the thesis is to explore and test the roles of attitude, preference conflict, norms and family identity in explaining intention/behavior toward fish consumption in Vietnamese families. This study utilizes a theoretical framework based on the Theory of Planned Behavior, but more focused on some other variables (ambivalence, family conflict and identity) in an extended model. The ...
    • The role of consumer satisfaction, consideration set size, variety seeking and convenience orientation in explaining seafood consumption in Vietnam 

      Ninh, Thi Kim Anh (Master thesis; Mastergradsoppgave, 2010-05-31)
      The study examines the relationship betweens convenience food and seafood consumption in Vietnam through a replication and an extension of studies of Rortveit and Olsen (2007; 2009). The main purpose of this study is to give an understanding of the role of consumers’ satisfaction, consideration set size, variety seeking, and convenience in explaining seafood consumption behavior in Vietnam.
    • The role of family communication and parents' feeding practices in children's food preferences 

      Alm, Siril; Olsen, Svein Ottar; Honkanen, Pirjo (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-02-07)
      This study used Family Communication Patterns Theory (FCPT) to explore how familydinner-related communication takes place and how parents’ feeding practices may be associated with children’s preferences for dinner meals. The sample consisted of 12 dyads with seven- and eight-year-old Norwegian children and their parents. In-depth photo interviews were used for collecting data. Interview transcripts ...
    • The role of gill raker number variability in adaptive radiation of coregonid fish 

      Kahilainen, Kimmo; Siwertsson, Anna; Gjelland, Karl Øystein; Knudsen, Rune; Bøhn, Thomas; Amundsen, Per-Arne (Journal article; Tidsskriftartikkel; Peer reviewed, 2010-07-27)
      Gill raker divergence is a general pattern in adaptive radiations of postglacial fish, but few studies have addressed the adaptive significance of this morphological trait in foraging and eco-evolutionary interactions among predator and prey. Here, a set of subarctic lakes along a diversifying gradient of coregonids was used as the natural setting to explore correlations between gill raker numbers ...

    • The role of marine mammals in the Barents Sea foodweb 

      Blanchet, Marie-Anne; Primicerio, Paul; Frainer, Andrè; Kortsch, Susanne; Skern-Mauritzen, Mette; Dolgov, Andrey V.; Aschan, Michaela (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-08-26)
      Marine mammals are important players in the Barents Sea ecosystem but their structural role in the foodweb has been little explored. We compare foodweb-related characteristics within and between phylogenetic groups for 19 marine mammals. As a group, they directly connect to the most central species (i.e cod and haddock) in the Barents Sea (i.e. cod and haddock) and consume over half of the available ...
    • The role of path–dependent institutions during the collapse and rebuilding of a fishery 

      Bertheussen, Bernt Arne (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-12-30)
      This article presents a historical analysis of the Norwegian spring spawning herring fishery. Theoretically, the study is rooted in new institutional economics (NIE). The study shows that the fishery collapsed during the 1960s because of overfishing. The underlying key drivers were unregulated open access management, technological progress, and excess capacity building. The analysis further ...

    • The role of predation and food limitation on claims for compensation, reindeer demography and population dynamics 

      Tveraa, Torkild; Stien, Audun; Brøseth, Henrik; Yoccoz, Nigel Gilles (Journal article; Tidsskriftartikkel; Peer reviewed, 2014-10)
      1.A major challenge in biodiversity conservation is to facilitate viable populations of large apex predators in ecosystems where they were recently driven to ecological extinction due to resource conflict with humans. 2. Monetary compensation for losses of livestock due to predation is currently a key instrument to encourage human–carnivore coexistence. However, a lack of quantitative estimates ...
    • The Role of Silicate in the Parasitism of Pleurosigma sp. Diatoms by the Thraustochytrid Phycophthorum isakeiti 

      Powers, Daniel Jerome Finley (Master thesis; Mastergradsoppgave, 2020-05-15)
      The recently described thraustochytrid diatom parasite Phycophthorum isakeiti has been isolated from the marine system of northern Norway (Hassett, 2020). Protist P. isakeiti’s ecological role, biodiscovery potential, and interactions with a possible diatom host, Pleurosigma sp. remain largely unexplored. Here I present culturing experiments to test whether P. isakeiti is an obligate parasite. To ...
