Long-term changes in taxonomic and functional composition of European marine fish communities
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-07-22)Evidence of large-scale biodiversity degradation in marine ecosystems has been reported worldwide, yet most research has focused on few species of interest or on limited spatiotemporal scales. Here we assessed the spatial and temporal changes in the taxonomic and functional composition of fish communities in European seas over the last 25 years (1994–2019). We then explored how these community changes ... -

Some issues related to the Svalbardian tectonic event (Ellesmerian Orogeny) in Svalbard
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-07-23)Svalbard has long been thought to represent the easternmost realm of the Ellesmerian Orogeny in the late Devonian or early Mississippian (Svalbardian tectonic event). Several authors do not agree and present alternative interpretations of the observed structures in older and more recent articles. This article discusses a number of issues that, in our opinion, are not sufficiently considered in ... -
Vitenskapelige stereotypier. Om konstruksjonen av samene som kulturhistorisk enhet i tida fram mot 1910
(Master thesis; Mastergradsoppgave, 2001)Rundt 1900 er arkeologien i Norge formalisert som vitenskapelig disiplin med vekt på det norske (Keller 1978, Opedal 1996). Det nasjonalistiske preget var ikke noe unikt for arkeologien her til lands; som den norske arkeologen Haakon Shetelig uttalte i 1910; “ det er nesten overalt det nationale som har været det drivende i den europeiske arkeologi” (Shetelig 1910:59). Til forskjell fra arkeologi i ... -

Unge utenfor arbeidsliv og skolegang. Ute av syne, ute av sinn?
(Master thesis; Mastergradsoppgave, 2023-11-13)Forskning viser at mange unge av ulike årsaker står langt utenfor arbeid og utdanning. Og selv om arbeidsledigheten er lav, øker andelen unge som blir ufør. Dette er en marginaliseringsprosess hvor de til slutt ender opp i ungt utenforskap. Forskning har i tillegg vist at stadig flere unge blir sykere og faller ut der de skal være inkludert. Psykiske lidelser er i økende grad en stor del av de høye ... -
Circadian coupling of mitochondria in a deep-diving mammal
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-04-08)Regulation of mitochondrial oxidative phosphorylation is essential to match energy supply to changing cellular energy demands, and to cope with periods of hypoxia. Recent work implicates the circadian molecular clock in control of mitochondrial function and hypoxia sensing. Because diving mammals experience intermittent episodes of severe hypoxia, with diel patterning in dive depth and duration, ... -
