Atlantic salmon Salmo salar and ballan wrasse Labrus bergylta display different susceptibility to clonal strains of Paramoeba perurans
(Journal article; Peer reviewed, 2020)Amoebic gill disease (AGD), caused by the marine amoeba Paramoeba perurans, is an important disease of farmed Atlantic salmon Salmo salar L. in Norway. The use of wrasse as cleaner fish in salmon net pens raises questions ... -
Atmospheric deposition effects on plankton communities in the Eastern Mediterranean: A mesocosm experimental approach
(Peer reviewed; Journal article, 2017-07-04)The effects of atmospheric deposition on plankton community structure were examined during a mesocosm experiment using water from the Cretan Sea (Eastern Mediterranean), an area with a high frequency of atmospheric aerosol ... -
Attuning to a changing ocean
(Journal article; Peer reviewed, 2020)The ocean is a lifeline for human existence, but current practices risk severely undermining ocean sustainability. Present and future social−ecological challenges necessitate the maintenance and development of knowledge ... -
Atypiske Vibrio anguillarum: Karakterisering og virulenstesting på torskeyngel Gadus morhua
(Master thesis, 2009-06-02)Atlantisk torsk Gadus morhua er en av de viktigste artene i norsk oppdrettsnæring, og produksjonen er stigende. Sykdomsproblemene er betydelige, og blant annet klassisk vibriose (infeksjoner med Vibrio anguillarum) forårsaker ... -
Audience matters: Multimodal projects across three international case studies
(Journal article; Peer reviewed, 2022)There is growing attention to student assessments designed to reach beyond the classroom, including assessments with an immediate or future audience. The impact of audience, however, has not been examined in multimodal ... -
Auto-Adhesion Potential of Extraocular Aqp0 during Teleost Development
(Peer reviewed; Journal article, 2016-05-06)AQP0 water channels are the most abundant proteins expressed in the mammalian lens fiber membranes where they are essential for lens development and transparency. Unlike other aquaporin paralogs, mammalian AQP0 has a low ... -
An automated approach for fringe frequency estimation and removal in infrared spectroscopy and hyperspectral imaging of biological samples
(Journal article; Peer reviewed, 2021)In infrared spectroscopy of thin film samples, interference introduces distortions in spectra, commonly referred to as fringes. Fringes may alter absorbance peak ratios, which hampers the spectral analysis. We have previously ... -
Autosomal sdY pseudogenes explain discordances between phenotypic sex and DNA marker for sex identification in Atlantic salmon
(Journal article; Peer reviewed, 2020)Despite the key role that sex-determination plays in evolutionary processes, it is still poorly understood in many species. In salmonids, which are among the best studied fishes, the master sex-determining gene sexually ... -
Back to Africa: monitoring post-hydropower restoration to facilitate reintroduction of an extinct-in-the-wild amphibian
(Peer reviewed; Journal article, 2014-08-11)Monitoring of the ecological efficiency of different restoration and mitigation measures is important to inform decision-making but can be challenging, especially in remote and low-resource settings. Species composition ... -
Bacterial biofilms on the kelp Laminaria hyperborea
(Doctoral thesis, 2011-03-23)This thesis deals with bacterial communities in biofilms on the surfaces of the kelp Laminaria hyperborea and their roles in carbon cycling. Kelp forests are characterized by high biodiversity and productivity, and cycling ... -
Bacterial community composition responds to changes in copepod abundance and alters ecosystem function in an Arctic mesocosm study
(Peer reviewed; Journal article, 2018)Combining a minimum food web model with Arctic microbial community dynamics, we have suggested that top-down control by copepods can affect the food web down to bacterial consumption of organic carbon. Pursuing this ... -
Bacterial Community Profiling of Tropical Freshwaters in Bangladesh
(Peer reviewed; Journal article, 2019)Seasonal and spatial variations in the bacterial communities of two tropical freshwater sources in Bangladesh, Lake Dhanmondi in central Dhaka, and a pond in the outskirts of Dhaka, were assessed and compared using PCR-DGGE ... -
Bacterial community structures in the Arctic Ocean: the effect of increased carbon load on nutrient competition and bacterial diversity
(Doctoral thesis, 2012-06-29)The Arctic Ocean is a unique marine environment with respect to irradiation periodicity and intensity, temperature, ice formation and strong stratification. Changes due to global warming might be more pronounced in this ... -
Bacterial growth control in marine environments : from experimental approaches to comparative analyses
(Doctoral thesis, 2010-12-14)To understand (1) the role of heterotrophic bacteria in the biogeochemical cycles, (2) the fate of the organic carbon and mineral nutrients, and (3) the flow of energy to higher trophic levels, we need to understand how ... -
Bacterial growth response to copepod grazing in aquatic ecosystems
(Peer reviewed; Journal article, 2007)The growth rate response of bacterial communities to the potential increase of dissolved organic matter (DOM) produced by the copepod Acartia tonsa was assessed in experiments conducted in three stations representing three ... -
Bacterial Response to Permafrost Derived Organic Matter Input in an Arctic Fjord
(Peer reviewed; Journal article, 2018-08-06)The warming of the Arctic causes increased riverine discharge, coastal erosion, and the thawing of permafrost. Together, this is leading to an increased wash out of terrestrial dissolved organic matter (tDOM) into the ... -
Bacteriophages targeting pathogenic bacteria isolated from lumpfish (Cyclopterus lumpus L.) and Atlantic salmon (Salmo salar L.)
(Master thesis, 2020-12-03)Bacterial diseases in aquaculture lead to reduced health and mortality of fish as well as economic consequences for the producer. Antibiotics are an important antimicrobial to control bacterial diseases, however, concerns ... -
Balanced harvest : concept, policies, evidence, and management implications
(Peer reviewed; Journal article, 2019-06-11)Balanced harvest has been proposed to reduce fishing impact on ecosystems while simultaneously maintaining or even increasing fishery yield. The concept has attracted broad interest, but also received criticisms. In this ... -
Balanced harvest: Utopia, failure, or a functional strategy?
(Peer reviewed; Journal article, 2016-04-21)Since “balanced harvest” was proposed in 2010 as a possible tool in the operationalization of the ecosystem approach to fisheries (EAF), the concept gained extensive international attention. Because maintaining ecosystem ... -
Ballan wrasse (Labrus bergylta) predation on hatchery reared scallop (Pecten maximus) spat
