Elevated water temperature in combination with an increase in daylength stimulate a synchronized onset of spermatogenesis in male Atlantic salmon (Salmo salar, L.) postsmolts
(Journal article; Peer reviewed, 2024)Male postsmolt maturation (“jacking”) is undesired in Atlantic salmon aquaculture due to economic and welfare impacts. Unfortunately, incidence of jacking has increased linked to intensive rearing conditions. This study ... -
Adaptive digital tissue deconvolution
(Journal article; Peer reviewed, 2024)Motivation The inference of cellular compositions from bulk and spatial transcriptomics data increasingly complements data analyses. Multiple computational approaches were suggested and recently, machine learning ... -
Structural dynamics of human deoxyuridine 5’-triphosphate nucleotidohydrolase (dUTPase)
(Journal article; Peer reviewed, 2024)Structural- and functional heterogeneity, as well as allosteric regulation, in homo-monomeric enzymes is a highly active area of research. One such enzyme is human nuclear-associated deoxyuridine 5’-triphosphate ... -
Ash dieback: A single-species catastrophe or a cascade of ecological effects in the ground flora?
(Journal article; Peer reviewed, 2024)Climate change and human activities have accelerated the spread of non-native species, including forest pests and pathogens, significantly contributing to global biodiversity loss. Pathogens pose a significant threat to ... -
Most of the escaped farmed salmon entering a river during a 5-year period were infected with one or more viruses
(Journal article; Peer reviewed, 2024)Disease interactions between farmed and wild populations have been poorly documented for most aquaculture species, in part due to the complexities to study this. Here, we tested 567 farmed Atlantic salmon escapees, captured ... -
The Indo-Pacific Pollen Database-a Neotoma constituent database
(Journal article; Peer reviewed, 2024)The Indo–Pacific Pollen Database (IPPD) is the brainchild of the late professor Geoffrey Hope, who gathered pollen records from across the region to ensure their preservation for future generations of palaeoecologists. ... -
Resilience of Juvenile Freshwater Pearl Mussels to Thermal Stress
(Journal article; Peer reviewed, 2024)Climate change poses a significant threat to freshwater ecosystems by causing increases of average water temperatures, and more frequent and extreme heating events. Freshwater mussels are declining globally, and the ... -
Genetic affiliations of miniaturized species and morphotypes within the Fucus genus (Phaeophyceae, Fucales)
(Journal article; Peer reviewed, 2024)In the North Atlantic members of the Fucus genus have an important ecological role, forming habitats in the littoral or upper sublittoral zones. A phylogeographic history with frequent hybridization and large phenotypical ... -
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 ... -
