Internasjonale studenter: Skal de bli eller må de dra?
(Chronicle; Kronikk, 2023-05-16)Stortinget skal snart behandle forslaget om at internasjonale studenter må betale høye studieavgifter. Om avgiftene innføres fra høsten, vil det etter alt å dømme bety færre internasjonale studenter, nedlegging av studieprogrammer, mindre mangfold og at vi mister kompetanse både i Norge og land i sør. Det med mindre vi nå tenker nytt og innovativt om finansiering. -

Timing is everything: Within-plant flowering phenology impacts fruit production in the Arctic-Alpine cushion plant Silene acaulis (L.) Jacq.
(Master thesis; Mastergradsoppgave, 2022-05-16)Timing is everything for Arctic flowering plants. Early flowers might be destroyed by frost, while late flowers have less time and resources to mature fruit. With climate change, Arctic flowering phenology is shifting. Yet for many species, phenology studies only encompass the onset of flowering and lack baseline data on within-plant flowering times. I used the gynodioecious cushion plant Silene ... -

Biokjemisk sammensetning i filet av vill og oppdrettet atlantisk laks (Salmo salar) - med hovedvekt på fettinnhold og fettsyresammensetning
(Master thesis; Mastergradsoppgave, 2018-05-15)Fisk og annen sjømat inneholder sunt fett, viktige vitaminer og mineraler, og er i tillegg en god kilde til protein. Hovedgrunnen til anbefalinger om å spise fisk og annen sjømat er det naturlig høye innholdet av de langkjedede omega-3 fettsyrene eikosapentaensyre (EPA) og dokosaheksensyre (DHA). Norsk oppdrettsnæring har siden oppstarten på 1970-tallet vokst til å bli en av landets viktigste næringer, ... -
Effect of simulated disturbance by geese on soil temperature and active layer thickness over one growing season
(Master thesis; Mastergradsoppgave, 2022-05-13)The Arctic is an area predicted to be strongly affected by climate change, and the extent of permafrost is expected to decrease. The insulating capacity of bryophytes is central in permafrost preservation. In High-Arctic Svalbard, disturbance by geese through grubbing may damage and remove parts of the bryophyte layer in moss tundra. The disruption is expected to lead to increased soil temperatures ... -
