    • Trends in mussel cover, density and size at exploited and unexploited intertidal reefs in eastern South Africa 

      Steyn, E.; Groeneveld, J.C.; Santos, Jorge; Mselegu, X.I. (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-20)
      The brown mussel Perna perna is the dominant indigenous mussel along the east coast of South Africa, where it is harvested by recreational and subsistence fishers. High fishing pressure near urban areas led to declining abundance and consequently to the closure of some reefs to fishing in 1998. We estimated trends in mussel population dynamics at exploited and unexploited sites, along fixed transects, ...

    • Triploid laks - Produktegenskaper og omdømmeperspektiver 

      Olsen, Terje Antero (Master thesis; Mastergradsoppgave, 2015-05-15)
      Sammendrag Oppdrett av laks har vært en suksesshistorie for Norge. Utviklingen har vært formidabel de siste tiårene fra en produksjon på ca. 46 000 tonn i 1984 til over 1,2 millioner tonn i 2014. Laksenæringen har imidlertid flere utfordringer og en av dem er rømming av laks fra sjøanlegg. Dette gir ikke bare et økonomisk tap for oppdretteren, men kan også føre til at rømt oppdrettslaks blander ...

      Johnsen, Erik (Master thesis; Mastergradsoppgave, 2007-11-15)
      Tema i oppgaven kan plasseres innenfor organisasjonsteorien, nærmere bestemt innenfor læring i organisasjoner og den lærende organisasjonen. Jeg skal se om mål TKE hadde før samlokaliseringen har blitt oppnådd innenfor disse områdene. Videre vil jeg se på om, eller i hvilken grad TKE er en lærende organisasjon. Foregår det noe som helst læring på organisasjonsnivået, eller skjer dette bare på ...
    • Trophic ecology of brown trout (Salmo trutta L.) in subarctic lakes 

      Sanchez-Hernandez, Javier; Amundsen, Per-Arne (Journal article; Tidsskriftartikkel; Peer reviewed, 2014-04-29)
      In subarctic lake systems, fish species like brown trout are often important predators, and their niche performance is a key characteristic for understanding trophic interactions and food web functioning at upper trophic levels. Here, we studied summer habitat use and stomach contents of brown trout under both allopatric and sympatric conditions in six subarctic lakes to reveal its trophic role, and ...
    • Trophic interactions and abiotic factors drive functional and phylogenetic structure of vertebrate herbivore communities across the Arctic tundra biome 

      Speed, James David Mervyn; Skjelbred, Ina Åsnes; Barrio, Isabel C.; Martin, Michael David; Berteaux, Dominique; Bueno, Guillermo; Christie, Katie; Forbes, Bruce C.; Forbey, Jennifer; Fortin, Daniel; Grytnes, John-Arvid; Hoset, Katrine Skamfer; Lecomte, Nicolas; Marteinsdottir, Bryndis; Mosbacher, Jesper Bruun; Pedersen, Åshild Ø.; Ravolainen, Virve; Rees, Eileen C.; Skarin, Anna; Sokolova, Natalya; Thornhill, Andrew H; Tombre, Ingunn; Soininen, Eeva M (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-29)
      Communities are assembled from species that evolve or colonise a given geographic region, and persist in the face of abiotic conditions and interactions with other species. The evolutionary and colonisation histories of communities are characterised by phylogenetic diversity, while functional diversity is indicative of abiotic and biotic conditions. The relationship between functional and phylogenetic ...
    • Trophic niche segregation among native whitefish and invasive vendace in a north Norwegian lake system 

      Kelly, Brianne; Amundsen, Per-Arne; Power, Michael (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-07)
      Introductions and invasions of non-native species alter nutrient cycling and trophic dynamics resulting in significant ecological disturbance. Stable isotope data were used to test for evidence of invader-induced trophic niche differences in a north Norwegian lake system differentially dominated by native European whitefish (<i>Coregonus lavaretus</i>) morphotypes and invasive vendace (<i>Coregonus ...
    • Trophic niche similarity among sea trout Salmo trutta in Central Norway investigated using different time-integrated trophic tracers 

      Davidsen, Jan Grimsrud; Knudsen, Rune; Power, Michael; Sjursen, Aslak Darre; Rønning, Lars; Hårsaker, Karstein; Næsje, Tor; Arnekleiv, Jo Vegar (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-11-21)
      From 2011 to 2013, anadromous brown trout Salmo trutta (213−730 mm, total body length, LT) were collected during or shortly after their marine feeding migration at 7 different localities in central Norway. The mean volume of stomach content (%) of marine fish prey eaten by S. trutta captured in marine waters varied from 34 to 89%. There was a high prevalence (67−100%) for parasite groups potentially ...
    • Trophic positions of mesozooplankton across the North Atlantic: estimates derived from biovolume spectrum theories and stable isotope analyses theories and stable isotope analyses 

      Basedow, Sünnje Linnéa; da Silva, Nuwan Alexandrio Lawrence; Bode, Antonio; van Beusekorn, Justus (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-10-03)
      The structure of marine pelagic food webs determines the fate of organic carbon and productivity, but it is difficult to measure. We compared two common methods (stable isotope analyses, SIAs, and biovolume spectrum theories, BSTs) of estimating trophic positions (TPs) of mesozooplankton. Two sets of stations across the North Atlantic (Iceland Basin, Irminger Basin, Labrador Sea) were clearly ...
    • Trophic relationships and the role of Calanus in the oceanic ecosystems south and north of Iceland 

      Pétursdóttir, Hildur (Doctoral thesis; Doktorgradsavhandling, 2012-12-03)
      The waters south and north of Iceland vary greatly both oceanographically and biologically with the rather stable and warm Atlantic waters south and west of Iceland and the more variable and cold Arctic and sub-Arctic waters, north and east of Iceland. The aim of this study was to increase the knowledge on the role of Calanus copepods and trophic relations of the key components of the oceanic ...
    • Trophic relationships in the Early Miocene Upper Marine Molasse of Baden-Württemberg, Southwest Germany, with special emphasis on the elasmobranch fauna 

      Höltke, Olaf; Salvador, Rodrigo Brincalepe; Rasser, Michael W. (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-11)
      The Early Miocene Upper Marine Molasse (OMM) in south-western Germany contains a diverse fossil ecosystem in which elasmobranch teeth are especially abundant. However, the scarcity of outcrops and sometimes poor preservation of fossils resulted in scant recent literature about the OMM. Here, we focus on the elasmobranch fauna to determine the trophic relationships within the OMM, using fossil ...

    • Trust versus perceived quality in scholarly publishing: A personality-attitude-intention approach 

      Moksness, Lars; Olsen, Svein Ottar (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-10-01)
      Digital academic journals serve as the main dissemination method for peer-reviewed research articles. These journals can be divided into two main categories: open access (OA) and non– open access (non-OA) journals. OA literature is defined by Suber as “digital, online, free of charge, and free of most copyright and licensing restrictions.” The reasons why no-cost OA adoption is slow-going ...
    • Trust-based management control in inter-organizational relationships 

      Wærness, Kristian; Solstad, Elsa Anita; Bertheussen, Bernt Arne (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-05)
      High levels of trust can reduce the risk of inter-organizational relationships failing. Also, high levels of trust between business partners can be advantageous as less time and effort are spent controlling the motives and behavior of a company’s counterpart. This case study explores the management control systems between two small Norwegian salmon farming companies engaged in a joint venture. ...
