The transcriptomic response of adult salmon lice (Lepeophtheirus salmonis) to reduced salinity
(Journal article; Peer reviewed, 2021)Salmon lice (Lepeophtheirus salmonis) are marine parasitic copepods living on salmonids and are challenging for salmon aquaculture. One of several treatment methods is the application of freshwater to the fish which can ... -
Transient photoreception in the hindbrain is permissive to the life history transition of hatching in Atlantic halibut
(Journal article; Peer reviewed, 2018)In nonmammalian vertebrates, photoreception takes place in the deep brain already early in development, but knowledge is lacking about the functions of these nonvisual photoreceptive systems. Prior to hatching, Atlantic ... -
Transition from heathland to scrub in south-eastern Tasmania: extent of change since the 1970s, floristic depletion and management implications
(Peer reviewed; Journal article, 2015-02)Heathland is a speciose and floriferous vegetation type, defined by its stature (<2 m) and dominance by scleromorphic shrubs. Heathland has been in decline globally, and much of its loss has been due to less frequent fire, ... -
Translocation and de novo synthesis of eicosapentaenoic acid (EPA) during nitrogen starvation in Nannochloropsis gaditana
(Peer reviewed; Journal article, 2019-01)The microalga Nannochloropsis gaditana is known for accumulating fatty acids, including the commercially interesting eicosapentaenoic acid (EPA) within the polar lipids (PL) and neutral lipids (NL). During microalgal growth ... -
Treeline and vegetation dynamics in response to environmental changes in Nepal, the central Himalaya
(Doctoral thesis, 2013-05-31)Aims: To describe and evaluate patterns of vegetation response to ongoing environmental changes across climate-limited (alpine treeline ecotone) and humanmodified (temperate Himalayan oak forests) ecosystems in Nepal, ... -
Trichlorfon, a salmon lice pesticide, and the effect on metabolism and inflammation in Atlantic salmon (Salmo salar, L.)
(Master thesis, 2020-06-26)Since the beginning of the salmon farming industry in Norway, the substantial fish health and welfare and economic costs caused by the parasitic salmon lice (Lepeophtheirus salmonis) has increased in tandem with the expanding ... -
Triploid atlantic salmon (Salmo salar L.) postsmolts accumulate prevalence more slowly than diploid salmon following bath challenge with salmonid alphavirus subtype 3
(Peer reviewed; Journal article, 2017-04-12)Triploid Atlantic salmon (Salmo salar L.) may play an important role in the sustainable expansion of the Norwegian aquaculture industry. Therefore, the susceptibility of triploid salmon to common infections such as salmonid ... -
Triploid Atlantic salmon and triploid Atlantic salmon × brown trout hybrids have better freshwater and early seawater growth than diploid counterparts
(Journal article; Peer reviewed, 2021)The use of reproductively sterile triploid salmonids would enhance the environmental sustainability of the aquaculture industry by preventing genetic exchange between escapees and wild conspecifics. To this end, we assessed ... -
Triploid induction in Atlantic cod (Gadus morhua L.) by the use of different pressure levels
(Master thesis, 2011-10-31)In the present experiment, different levels of pressure were investigated to see if it was possible to induce triploidy at a lower pressure level than previously used for Atlantic cod (Gadus morhua). Newly fertilized eggs ... -
Triploidisering av Atlantisk torsk (Gadus morhua); effekt av varierende hydrostatisk trykk og trykktidspunkt på triploiditet, samt konsekvenser for utvikling.
(Master thesis, 2013-10-31)Flere av utfordringene i norsk torskeoppdrett, er direkte eller delvis knyttet opp mot fiskens kjønnsmodningsfase. Kjønnsmodning fører blant annet til redusert appetitt og vekt, dårligere filetkvalitet samt høyere dødelighet. ... -
Triploidy leads to a mismatch of smoltification biomarkers in the gill and differences in the optimal salinity for post-smolt growth in Atlantic salmon
(Journal article; Peer reviewed, 2022)Sterile triploid Atlantic salmon (Salmo salar) show inconsistent seawater grow-out, but the reason why remains unclear. The purpose of this study was to determine the salinity optima of triploid post-smolts. Diploids and ... -
Trofiske interaksjoner mellom appendicularia (halesekkdyr) og marine virus – konsekvens for virus diversitet, spredning og persistens.
(Master thesis, 2018-09-01)The appendicularian Oikopleura dioica (Chordata:Tunicata) is a mesozooplanktonic marine organism that utilizes a gelatinous house to effectively trap microscopic particles from seawater. Earlier observations of the ... -
Trophic interactions and abiotic factors drive functional and phylogenetic structure of vertebrate herbivore communities across the Arctic tundra biome
(Peer reviewed; Journal article, 2019)Communities are assembled from species that evolve or colonise a given geographic region, and persist in the face of abiotic conditions and interactions with other species. The evolutionary and colonisation histories of ... -
Trophic structure of mesopelagic species in the Northeast Atlantic Ocean based on stable isotopes of carbon and nitrogen
(Master thesis, 2021-09-03)The mesopelagic zone is one of the largest, yet among the least explored habitats of the planet. Possible estimates of fish living in this zone range from around 1 to 15 billon tones of biomass which is 10 to 15 times that ... -
Tsv-N1: A novel DNA algal virus that infects tetraselmis striata
(Peer reviewed; Journal article, 2015-07-17)Numbering in excess of 10 million per milliliter of water, it is now undisputed that aquatic viruses are one of the major factors shaping the ecology and evolution of Earth’s microbial world. Nonetheless, environmental ... -
Tuning and Development of an Individual-Based Model of the Herring Spawning Migration
(Journal article; Peer reviewed, 2022-01-13)Norwegian spring spawning herring is a migratory pelagic fish stock that seasonally navigates between distant locations in the Norwegian Sea. The spawning migration takes place between late winter and early spring. In this ... -
