Reviews and syntheses: Biological indicators of low-oxygen stress in marine water-breathing animals
(Journal article; Peer reviewed, 2024)Anthropogenic warming and nutrient over-enrichment of our oceans have resulted in significant, and often catastrophic, reductions in dissolved oxygen (deoxygenation). Stress on water-breathing animals from this deoxygenation ... -
Colonization and extinction lags drive non-linear responses to warming in mountain plant communities across the Northern Hemisphere
(Journal article; Peer reviewed, 2024)Global warming is changing plant communities due to the arrival of new species from warmer regions and declining abundance of cold-adapted species. However, experimentally testing predictions about trajectories and rates ... -
Possible transport routes of IgM to the gut of teleost fish
(Journal article; Peer reviewed, 2024)Fish rely on mucosal surfaces as their first defence barrier against pathogens. Maintaining mucosal homeostasis is therefore crucial for their overall well-being, and it is likely that secreted immunoglobulins (sIg) play ... -
Ethical approaches for engaging extended peer communities: Insight into responsible workshopping with citizens
(Journal article; Peer reviewed, 2025)The United Nation’s Sustainable Development Goals (SDGs) represent the most ambitious and encompassing global framework for ecological, economic, and social sustainability for our planet to date. However, the relevance of ... -
The parasitic copepod, Sarcotretes scopeli Jungersen, 1911 castrate its mesopelagic fish host Benthosema glaciale
(Journal article; Peer reviewed, 2024)The mesopelagic fish Benthosema glaciale [Actinopterygii: Myctophiformes: Myctophidae], abundant in open ocean and deep fjords, is targeted for future exploitation despite existing knowledge gaps on population vital rates. ... -
Systematic revision of Orbiniidae (Annelida)
(Doctoral thesis, 2025-02-07)Orbiniidae er en mangfoldig gruppe annelider, som omfatter mer enn 200 beskrevne arter gruppert i 20 slekter. Orbiniider er vanlige og rikelig i bløtbunnssamfunn, og utgjør et viktig ledd i bentiske næringskjeder (inkludert ... -
The orientation mechanisms of juvenile Atlantic lumpfish (Cyclopterus lumpus) and the role of geomagnetic cues in their migration
(Master thesis, 2024-11-20)The Atlantic lumpfish (Cyclopterus lumpus) is a species that is of both ecological and economic importance, yet its migratory orientation mechanisms are poorly understood. This study investigated whether juvenile lumpfish ... -
Freshwater history influences farmed Atlantic salmon (Salmo salar) performance in seawater
(Journal article; Peer reviewed, 2024)The quality of smolts is one of the key factors for successful salmon production. We compared growth performance, physiological traits, and environmental adaptation in Atlantic salmon (Salmo salar) after transfer into a ... -
A multi-omics approach to Fervidobacterium, a group of thermophilic feather-degrading anaerobes
(Doctoral thesis, 2025-02-14)Keratin er et av de mest tallrike molekylene på jorden og utmerker seg også for sin motstandskraft og holdbarhet. Det er et strukturelt protein som finnes i epidermis hos virveldyr, hovedsakelig involvert i isolasjons- og ... -
Comparing physiological responses of acute and chronically stressed diploid and triploid Atlantic salmon (Salmo salar)
(Journal article; Peer reviewed, 2024)We compared the performance and physiological response of diploid and triploid Atlantic salmon (Salmo salar) following 21 days of either unpredictable chronic stress (UCS) or no disturbance (control). Thereafter, all four ... -
The Core of the Matter—Importance of Identification Method and Biological Replication for Benthic Marine Monitoring
(Journal article; Peer reviewed, 2024)Benthic macrofauna are important and widely used biological indicators of marine ecosystems as they have limited mobility and therefore integrate the effects of local environmental stressors over time. Recently, environmental ... -
Water treatment of recirculating aquaculture system (RAS) effluent water through microalgal biofilms
(Journal article; Peer reviewed, 2024)This research studied the growth of microalgae (Chlorella vulgaris and Phaeodactylum tricornutum) on a biofilm reactor using effluent water from salmon production in a recirculating aquaculture system (RAS). RAS effluent ... -
Onset of circadian rhythmicity in the brain of Atlantic salmon is linked to exogenous feeding
(Journal article; Peer reviewed, 2024)An organism’s biological processes are adapted to and driven by rhythmicity in the natural environment and periodicity of light is one of the most influential factors. In a developing organism, the onset of circadian ... -
Cell death induced by Lepeophtheirus salmonis labial gland protein 3 in salmonid fish leukocytes: A mechanism for disabling host immune responses
(Journal article; Peer reviewed, 2024)The salmon louse (Lepeophtheirus salmonis) is an ectoparasite feeding on mucus, skin, and blood of salmonids. On parasitised fish erosions and, at later lice stages, ulcerations appear at the louse feeding site. In susceptible ... -
Functional characterisation of salmon louse (Lepeophtheirus salmonis) labial gland proteins: Implications for host immune modulation and anti-coagulation
(Doctoral thesis, 2025-01-31)Den ektoparasittiske lakselusen, som infesterer laksefisk mens den spiser på vertens slim, hud og blod, utgjør et betydelig problem for oppdrett av atlantisk laks. Nåværende behandlingsstrategier er ikke bærekraftige og ... -
Biofilter and degasser performance at different alkalinity levels in a brackish water pilot scale recirculating aquaculture system (RAS) for post-smolt Atlantic salmon
(Journal article; Peer reviewed, 2024)Maintaining pH stability in Recirculating Aquaculture Systems (RAS) is essential, as it has a direct impact on the toxicity of ammonia, CO2, and other metabolite compounds, as well as the efficiency of critical processes ... -
