      Eriksen, Emma Falkeid; Andrews, Adam Jon; Nielsen, Svein Vatsvåg; Persson, Per; Malca, Estrella; Onar, Vedat; Aniceti, Veronica; Piquès, Gäel; Piattoni, Federica; Fontani, Francesco; Wiech, Martin; Ferter, Keno; Kersten, Oliver Sven; Ferrari, Giada; Cariani, Alessia; Tinti, Fausto; Cilli, Elisabetta; Atmore, Lane M.; Star, Bastiaan (Journal article; Tidsskriftartikkel; Peer reviewed, 2025-02-07)
      Mitonuclear discordance between species is readily documented in marine fishes. Such discordance may either be the result of past natural phenomena or the result of recent introgression from previously seperated species after shifts in their spatial distributions. Using ancient DNA spanning five millennia, we here investigate the long-term presence of Pacific bluefin tuna (Thunnus orientalis) and ...

      Ei bok om friluftslivets historie, samfunnsmessige betydning, verdigrunnlag og forvaltningskontekster
    • Tilrettelegging for friluftsliv 

      Viken, Arvid Ingmar (Chapter; Bokkapittel, 2025-01-02)
      Den rette linja mellom to punkter i landskapet er ikke alltid den raskeste. Det lønner seg ofte å gå i buer, for å unngå bratte skrenter, komme rundt et stup, eller bare en oppgått sti. Stier slynger seg mellom fjell og gjennom søkk og daler der det er lettest å ta seg frem. Enkelte steder er stiene bearbeidet, eller tilrettelagt som man gjerne kaller det; klopper over myrer, bruer over elver, trapper ...

    • The Automated Tourism and Hospitality Company of the Future 

      Ivanov, Stanislav; Vespestad, May Kristin (Chapter; Bokkapittel, 2024-10-15)
      In the robonomic economic system many tourism and hospitality companies will be completely automated, and some of them may not even have any human employees. It means that we must rethink the way tourism attractions are created, the way tourism experiences are designed, and the practices of tourism and hospitality companies. We need to consider how to cater for tourists in ways that prove viable ...

    • Ut på tur: Refleksjoner rundt turlivet 

      Viken, Arvid Ingmar (Chapter; Bokkapittel, 2025-01-08)
      Dette kapittelet handler om å gå på tur. Det er noe de fleste av oss gjør hele tida, vi går skogsturer, fjellturer, skiturer, toppturer og mye mer. Men vi har også andre ord for dette; vi vandrer og lager vandreruter i fjellet, vi bruker terrenget, vi rusler og jogger – vi beveger oss. Bevegelser er helt sentralt for mennesket, å gå er nesten som hjerteslag og pust, helt fundamentalt for livet – ...
    • Forvaltning og ikke-forvaltning av elv og skog i Nord-Troms 

      Viken, Arvid Ingmar (Journal article; Tidsskriftartikkel; Peer reviewed, 2024)
      Artikkelen sammenlikner forvaltninga av to områder i Nordreisa og friluftsaktiviteter som foregår der. Det ene er Reisaelva med laksefiske, mens det andre er Kjellerskogen hvor det inntil nylig foregikk hundespanntrening samtidig som skogen i lang tid har blitt benyttet til sauebeite. Det har tidvis vært konflikter knyttet til begge områdene. For elva ble det opprettet et regime som styrer aktivitetene. ...

      Gillnets are widely used fishing gear for targeting various fish species. Gillnet fisheries use different gear configurations such as different mesh sizes and number of netting twines (mono- or multifilament) depending on the species targeted. Gillnet fishery targeting whiting (Merlangius merlangus) is one of the economically important year-round fisheries in the Black Sea. However, large bycatch ...
    • Use of floated gillnet to reduce flatfish bycatch in a mixed-species gillnet fishery 

      Yu, Mengjie; Herrmann, Bent; Cerbule, Kristine; Liu, Changdong; Zhang, Liyou; Tang, Yanli (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-05-24)
      Bycatch of threatened flatfish species is a major concern in mixed-species bottom-set gillnet fisheries in the Yellow Sea, China. Therefore, we tested floated gillnets against standard bottom-set gillnets to reduce bycatch by exploiting difference in species-specific fish behavior. Our results demonstrated that the floated gillnet design can greatly improve species and size selectivity. Floated ...
