Microbial dynamics in high latitude ecosystems. Responses to mixing, runoff and seasonal variation a rapidly changing environment
(Doctoral thesis, 2017-11-08)The pronounced warming at high latitude alters a range of physical conditions i.e. the magnitude of runoff, sea-ice extent and strength of stratification and thus affect the biological systems. As microorganisms form the ... -
Microbial inventory of deeply buried oceanic crust from a young ridge flank
(Peer reviewed; Journal article, 2016-05-27)The deep marine biosphere has over the past decades been exposed as an immense habitat for microorganisms with wide-reaching implications for our understanding of life on Earth. Recent advances in knowledge concerning this ... -
Microbial iron reduction and greenhouse gas production in response to organic matter amendment and temperature increase of periglacial sediments, Bolterdalen, Svalbard
(Journal article; Peer reviewed, 2022)Arctic permafrost soils store substantial reserves of organic matter (OM) from which microbial transformation contributes significantly to greenhouse gas emissions of CH4 and CO2. However, many younger sediments exposed ... -
Microbial Nitrogen Cycling in the Marine Deep Biosphere
(Doctoral thesis, 2018-11-22) -
Microbial nitrogen dynamics in organic and mineral soil horizons along a latitudinal transect in western Siberia
(Peer reviewed; Journal article, 2015-05-12)Soil N availability is constrained by the breakdown of N-containing polymers such as proteins to oligopeptides and amino acids that can be taken up by plants and microorganisms. Excess N is released from microbial cells ... -
A Microbial Nitrogen Engine Modulated by Bacteriosyncytia in Hexactinellid Sponges: Ecological Implications for Deep-Sea Communities
(Journal article; Peer reviewed, 2021-03-17)Hexactinellid sponges are common in the deep sea, but their functional integration into those ecosystems remains poorly understood. The phylogenetically related species Schaudinnia rosea and Vazella pourtalesii were herein ... -
Microbial winter and spring bloom dynamics in a high Arctic fjord
(Master thesis, 2014-06-02)Knowledge of the seasonal dynamics within the Arctic marine microbial network is scarce, particularly during the polar night period. The abundances of different microbial groups in Adventfjorden, Svalbard were investigated ... -
Microbiological aspects of fish handling and processing in the Norwegian pelagic sector
(Doctoral thesis, 2015-03-17)Most global marine fish resources seem to have reached their limit of sustainable exploitation, whereas the demand for high quality fish products is still increasing. The fish sector needs to comply with the growing market ... -
Microbiological assessment along the fish production chain of the Norwegian pelagic fisheries sector - Results from a spot sampling programme
(Peer reviewed; Journal article, 2015-10)Microbes play an important role in the degradation of fish products, thus better knowledge of the microbiological conditions throughout the fish production chain may help to optimise product quality and resource utilisation. ... -
The Microbiome and Occurrence of Methanotrophy in Carnivorous Sponges
(Peer reviewed; Journal article, 2016-11-09)As shown by recent studies, filter-feeding sponges are known to host a wide variety of microorganisms. However, the microbial community of the non-filtering carnivorous sponges (Porifera, Cladorhizidae) has been the subject ... -
Microbiome dataset from a marine recirculating aquaculture system (RAS) for salmon post-smolt production in Norway
(Journal article; Peer reviewed, 2022)A marine aquaculture recycling system (RAS) for the production of post-smolt was monitored for microbial community structures during the first year of operation. Sample material was obtained monthly from the biofilter ... -
Microbiomes of Hadal Fishes across Trench Habitats Contain Similar Taxa and Known Piezophiles
(Journal article; Peer reviewed, 2022)Hadal snailfishes are the deepest-living fishes in the ocean, inhabiting trenches from depths of ∼6,000 to 8,000 m. While the microbial communities in trench environments have begun to be characterized, the microbes ... -
Micromonas versus virus: New experimental insights challenge viral impact
(Peer reviewed; Journal article, 2017-05)Viruses have recurrently been hypothesized as instrumental in driving microbial population diversity. Nonetheless, viral mediated co-existence of r/kstrategists, predicted in the Killing-the-Winner (KtW) hypothesis, remains ... -
Micronekton biomass distribution, improved estimates across four north Atlantic basins
(Peer reviewed; Journal article, 2019)Distribution of micronekton was investigated during early summer of 2013, using data from a cruise covering the central parts of four north Atlantic basins, the Norwegian Sea (NS), Iceland Sea (ICS), Irminger Sea (IRS), ... -
Microplastic variability in subsurface water from the Arctic to Antarctica
(Journal article; Peer reviewed, 2022)Comparative investigations of microplastic (MP) occurrence in the global ocean are often hampered by the application of different methods. In this study, the same sampling and analytical approach was applied during five ... -
Microplastics in arctic invertebrates- Status on occurrence and recommendations for future monitoring
(Journal article; Peer reviewed, 2022)Few studies have been published on occurrence and distribution on microplastics (MPs) in invertebrates from the Arctic. We still need to develop harmonised methods to enable good comparison between studies taking into ... -
Microrefugia and shifts of Hippophae tibetana (Elaeagnaceae) on the north side of Mt. Qomolangma (Mt. Everest) during the last 25000 years
(Peer reviewed; Journal article, 2014-05-19)Microrefugia at high altitudes or high latitudes are thought to play an important role in the post-glacial colonization of species. However, how populations in such microrefugia have responded to climate changes in alternating ... -
Microsomal triglyceride transfer protein in the ectoparasitic crustacean salmon louse (Lepeophtheirus salmonis)
(Peer reviewed; Journal article, 2017-08)The salmon louse, Lepeophtheirus salmonis, is an endemic ectoparasite on salmonid fish that is challenging for the salmon farming industry and wild fish. Salmon lice produce high numbers of offspring, necessitating ... -
Migration of Atlantic salmon post-smolts in a fjord with high infestation pressure of salmon lice
(Peer reviewed; Journal article, 2018)Understanding Atlantic salmon Salmo salar post-smolt coastal migration behaviour is crucial for predicting their exposure to ecological challenges such as the parasite salmon louse Lepeophtheirus salmonis. We compared the ... -
