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 ... -
Miljø-DNA påvisning av Pasteurella atlantica gv. salmonicida
(Master thesis, 2022-05-16)Pasteurellose forårsaket av Pasteurella atlantica gv. salmonicida hos atlantisk laks (Salmo salar L.) har de siste årene etablert seg som en bakteriesykdom som truer fiskevelferd og bærekraftig produksjon i den norske ... -
Miljøundersøking av Tveitevatnet og Fjøsangervassdraget i Bergen, med fokus på abbor (Perca fluviatilis) som indikatororganisme
(Master thesis, 2015-01-28)Tveitevatnet (Årstad bydel, Bergen kommune) har lenge vore påverka av forureina sigevatn fra eit gammalt deponi på Slettebakken i tillegg til industri i næromradet, noko som har gjort at miljøgifter som PCB og tungmetall ... -
Mining Lepeophtheirus salmonis RNA-Seq data for qPCR reference genes and their application in Caligus elongatus
(Journal article; Peer reviewed, 2023)Lepeophtheirus salmonis and Caligus elongatus are two parasitic copepod species posing a significant threat to salmonid aquaculture. Consequently, several gene expression studies are executed each year to gain new knowledge ... -
The Miocene: The Future of the Past
(Journal article; Peer reviewed, 2021)The Miocene epoch (23.03–5.33 Ma) was a time interval of global warmth, relative to today. Continental configurations and mountain topography transitioned toward modern conditions, and many flora and fauna evolved into the ... -
Mitigation of oxygen decline in fjords by freshwater injection
(Journal article; Peer reviewed, 2023)The exchange of water masses between deep fjords and the open ocean is commonly constrained by a topographical barrier called the sill. While fjord water above the sill depth communicates relatively freely with the open ... -
Mitochondrial aquaporin-8-mediated hydrogen peroxide transport is essential for teleost spermatozoon motility
(Peer reviewed; Journal article, 2015-01-14)Reactive oxygen species (ROS), particularly hydrogen peroxide (H2O2), cause oxidative cell damage and inhibit sperm function. In most oviparous fishes that spawn in seawater (SW), spermatozoa may be exposed to harmful ROS ... -
Mitogenomics of the suborder Cottoidei (Teleostei: Perciformes): Improved assemblies, mitogenome features, phylogeny, and ecological implications
(Journal article; Peer reviewed, 2022)We determined the mitogenome of Cyclopterus lumpus using a hybrid sequencing approach, and another four closely related species in the Liparidae based on available next-generation sequence data. We found that the mitogenome ... -
Mixed-stock analysis of Atlantic herring (Clupea harengus): a tool for identifying management units and complex migration dynamics
(Journal article; Peer reviewed, 2023)We developed and validated a mixed-stock analysis (MSA) method with 59 single-nucleotide polymorphisms selected from genome-wide data to assign individuals to populations in mixed-stock samples of Atlantic herring from the ... -
Mixture effects of environmental contaminants in Atlantic cod (Gadus morhua) : Combining experimental approaches to study contaminant-induced biological responses
(Doctoral thesis, 2022-01-15)Release of chemicals from anthropogenic activities is considered a substantial threat to the global environment. Marine ecosystems are sinks for accumulation of contaminants, therefore marine organisms are highly susceptible ... -
MLVA genotyping of Moritella viscosa reveals serial emergence of novel, host-specific clonal complexes in Norwegian salmon farming
(Journal article; Peer reviewed, 2023)A Multi-Locus Variable number of tandem repeat Analysis (MLVA) genotyping scheme was developed for the epidemiological study of Moritella viscosa, which causes ‘winter ulcer’ predominantly in sea-reared Atlantic salmon ... -
Mn/Fe reduction in sandy soil during degradation of de-icing chemical: Respiration kinetics and prokaryotic community composition
(Master thesis, 2017-08-29)At Oslo airport, Gardermoen, Norway, large quantities of propylene glycol (PG) are used as de-icing fluid during winter, causing high loads of this chemical to infiltrate in surrounding soil during snow melt and increasing ... -
A model for hydrophobic protrusions on peripheral membrane proteins
(Peer reviewed; Journal article, 2018-07-26)With remarkable spatial and temporal specificities, peripheral membrane proteins bind to biological membranes. They do this without compromising solubility of the protein, and their binding sites are not easily distinguished. ... -
Model of mesopelagic fish predation on eggs and larvae shows benefits of tuna spawning under full moon
(Journal article; Peer reviewed, 2023)Most mesopelagic fish are small planktivores that migrate up at nightfall to feed in the safety of darkness and descend to depth at dawn to escape visual predators. However, the trophic roles can reverse since mesopelagic ... -
Model-informed classification of broadband acoustic backscatter from zooplankton in an in situ mesocosm
(Journal article; Peer reviewed, 2023)Classification of zooplankton to species with broadband echosounder data could increase the taxonomic resolution of acoustic surveys and reduce the dependence on net and trawl samples for ‘ground truthing’. Supervised ... -
