Male bearded seals use vocal displays to attract females and compete with other males during the mating period, making it possible to monitor breeding populations using passive acoustic monitoring (PAM). This study analysed year-round acoustic data from underwater recorders at three sites with different environmental conditions in Svalbard (Norway). Male bearded seals vocalised for an extended ...

Underernæring og dårlig matlyst blant sykehjemsbeboere er et aktuelt tema både i media og innenfor helse- og omsorgssektoren. Det er et tilsynelatende fokus på mat og ernæring, men det finnes lite informasjon om hva beboerne selv mener om måltidsituasjonen. Formålet med denne studien er å undersøke hvordan beboere på sykehjem/helseinstitusjon opplever middagsmåltidet basert på individenes sanseinntrykk ...

Nettverksteorien forteller oss at bedrifter med utstrakte nettverk og heterogene samarbeidspartnere har tilgang på en bred kunnskapsbase utenfor bedriften, som kan være avgjørende for bedriftens konkurranseevne. Tema for denne oppgaven er bedrifters bruk av nettverk, og hva som gjør at noen bedrifter bruker nettverket mer aktivt enn andre. I oppgaven fokuseres det på denne sammenhengen hos nordnorske ...

Fast and intuitive thinking, as well as emotions, play a large role in decision-making. The sociology of wise practice within public administration also suggests that thinking preferences like the use of intuition form a cornerstone of public administrators’ virtuous practice. This contribution uses conceptual and theoretical resources from behavioral sciences and public administration to find out ...

Bruk av rensefisk i oppdrett har økt enormt de siste årene, fordi de spiser lakselus, en parasitt som lever på skinnet til laksefisk. Interessen for rognkjeks er spesielt stor, da den har vist seg å være en effektiv lusespiser, selv med lave temperaturer i havet. All rognkjeks som brukes i kommersielle oppdrettsanlegg i dag er etterkommere av foreldre som fangstes vilt. Årsaken er at rognkjeksen ...

In this paper we address the sunk cost effect with behavioural investment. From an incentivized task in a survey with a built-in game of two parts. Part one is a game with a 2X2 design: High sunk cost condition, High and Low treatment group. And Relevant sunk cost condition, Relevant and Irrelevant treatment group. The game is where subjects put in time and effort, for which the attributes of the ...

Analysis of video recordings performed by the submersible “Nautile” in the Bay of Biscay, NE Atlantic indicated that demersal fish species are associated to different types of deep-sea habitats. Four different dive transects were analysed with respect to environmental characteristics. A total of 19 fish groups were ordinated by means of canonical correspondence analysis, and the investigation ...

Climate change-induced alterations of aquatic ecosystems, increased water temperature and human activity are substantial stressors to anadromous Arctic charr, and these are all expected to increase in the future. The knowledge of the marine behaviour of anadromous Arctic charr, especially post-smolts, is limited and few studies has described their residency at sea in detail. Therefore, more ...

Salmon lice can impact the marine behaviour, growth, and survival of salmonids, but little is known about their effects on Arctic char. We present behavioural responses from the first dose-response experiment with wild anadromous Arctic char (n = 50) infested in situ with salmon lice (0.0–1.2 lice g⁻¹ fish) in an area with low natural infestations. Infested fish spent less time at sea ...

In northernmost Norway the right to own and manage the land in Finnmark, was transferred from the state to the the Finnmark Estate (FeFo) in 2005. The land tenure arrangement was a result of land claims made by the indigenous Sami people of Norway. The resources and the land that was previously managed to the best for all Norwegian citizens by the state, is now managed to the best for the ...
