Evaluation of stress in farmed Atlantic salmon (Salmo salar) using different biological matrices
(Journal article; Peer reviewed, 2024)Atlantic salmon were subjected to an acute crowding scenario, and their subsequent stress responses were observed under three distinct swimming speed/water flow (WF) conditions: 0.5, 1, and 1.5 body lengths per second ... -
Genetic adaptations for the oceanic success of fish eggs
(Journal article; Peer reviewed, 2024)Genetic adaptations of organisms living in extreme environments are fundamental to our understanding of where life can evolve. Water is the single limiting parameter in this regard, yet when released in the oceans, the ... -
Mesopelagic Fish Traits: Functions and Trade-Offs
(Journal article; Peer reviewed, 2024)Fishes inhabiting the mesopelagic zone of the world's oceans are estimated to account for the majority of the world's fish biomass. They have recently attracted new attention because they are part of the biological carbon ... -
Assessing between-individual variability in bioenergetics modelling: Opportunities, challenges, and potential applications
(Journal article; Peer reviewed, 2024)Population dynamics is influenced by between-individual variability. Dynamic Energy Budget (DEB) theory is an appealing framework for assessing such a variability, yet DEB parameters have rarely been estimated at the ... -
Biomolecular profiles of Arctic sea-ice diatoms highlight the role of under-ice light in cellular energy allocation
(Journal article; Peer reviewed, 2024)Arctic sea-ice diatoms fuel polar marine food webs as they emerge from winter darkness into spring. Through their photosynthetic activity they manufacture the nutrients and energy that underpin secondary production. Sea-ice ... -
Polycladomyces zharkentensis sp. nov., a novel thermophilic cellulose-and starch-degrading member of the Bacillota from a geothermal aquifer in Kazakhstan
(Journal article; Peer reviewed, 2024)A thermophilic, aerobic and heterotrophic filamentous bacterium, designated strain ZKZ2T, was isolated from a pipeline producing hydrothermal water originating from a >2.3 km deep subsurface geothermal source in Zharkent, ... -
Identifying the optimal landscape configuration for landscape multifunctionality
(Journal article; Peer reviewed, 2024)Increased pressure on land resources to provide multiple benefits calls for landscape strategies that optimize the supply of multiple ecosystem services (ES). Previous research into the drivers of landscape multifunctionality ... -
Premises for a digital twin of the Atlantic salmon in its world: Agency, robustness, subjectivity and prediction
(Journal article; Peer reviewed, 2024)Aquaculture of Atlantic salmon Salmo salar is in transition to precision fish farming and digitalization. As it is easier, cheaper and safer to study a digital replica than the system itself, a model of the fish can ... -
Structure of Benthic Microbial Communities in the Northeastern Part of the Barents Sea
(Journal article; Peer reviewed, 2024)The Barents Sea shelf is one of the most economically promising regions in the Arctic in terms of its resources and geographic location. However, benthic microbial communities of the northeastern Barents Sea are still ... -
Species assignment from seal diet samples using shape analyses in a machine learning framework
(Journal article; Peer reviewed, 2024)The identification and quantification of prey ingested is a limiting factor in trophic ecology studies and is fundamental for assessing the impact of a predator on prey populations. Vendace (Coregonus albula) and whitefish ... -
Transcriptome responses to benzo[a]pyrene in liver slices of sub-arctic fish species
(Journal article; Peer reviewed, 2024)Due to the expanding oil-related activities, the arctic and sub-arctic marine environments are increasingly vulnerable to oil-related pollution such as accidental oil spills. These cold-water ecosystems harbor many fish ... -
Global Lake Health in the Anthropocene: Societal Implications and Treatment Strategies
(Journal article; Peer reviewed, 2024)The world's 1.4 million lakes (≥10 ha) provide many ecosystem services that are essential for human well-being; however, only if their health status is good. Here, we reviewed common lake health issues and classified them ... -
Plant trait and vegetation data along a 1314 m elevation gradient with fire history in Puna grasslands, Perú
(Journal article; Peer reviewed, 2024)Alpine grassland vegetation supports globally important biodiversity and ecosystems that are increasingly threatened by climate warming and other environmental changes. Trait-based approaches can support understanding of ... -
The importance of migratory drop-off for island colonization in birds
(Journal article; Peer reviewed, 2024)Seasonal migration is an underappreciated driver of animal diversification. Changes in migratory behaviour may favour the establishment of sedentary founder populations and promote speciation if there is sufficient ... -
Too much diversity—Multiple definitions of geodiversity hinder its potential in biodiversity research
(Journal article; Peer reviewed, 2024)Geodiversity—the diversity of abiotic features and processes of the Earth's surface and subsurface—is an increasingly used concept in ecological research. A growing body of scientific literature has provided evidence of ... -
Evidence- based policymaking: Exploring the effectiveness of salmon aquaculture management in Norway
(Doctoral thesis, 2025-03-21)Norge er verdens største produsent av atlantisk laks (Salmo salar). For å sikre en miljømessig bærekraftig næring innførte Norge i 2017 det såkalte Trafikklyssystemet. Videre vekst i næringen skulle vurderes gjennom ... -
The protistan parasite Marteilia pararefringens (Paramyxida) in bivalves and its distribution along the Norwegian coast
(Doctoral thesis, 2025-03-25)I Norge har man overvåket for parasittsykdommen marteiliose, forårsaket av Marteilia refringens, siden 1995 i flatøsters Ostrea edulis og 2010 i blåskjell Mytilus spp. Veterinærinstituttet hadde ansvaret for overvåkningsprogrammet ... -
At what cost? The impact of bacteriophage resistance on the growth kinetics and protein synthesis of Escherichia coli
(Journal article; Peer reviewed, 2024)Cost of bacteriophage resistance (COR) is important in explaining processes of diversification and coexistence in microbial communities. COR can be expressed in different traits, and the lack of universally applicable ... -
A slow-fast trait continuum at the whole community level in relation to land-use intensification
(Journal article; Peer reviewed, 2024)Organismal functional strategies form a continuum from slow- to fast-growing organisms, in response to common drivers such as resource availability and disturbance. However, whether there is synchronisation of these ... -
