Traits help explain species' performance away from their climate niche centre
(Journal article; Peer reviewed, 2023)Aim: Climate change impacts on biota are variable across sites, among species and throughout individual species' ranges. Niche theory predicts that population performance should decline as site climate becomes increasingly ... -
Transcriptome responses in copepods Calanus finmarchicus, Calanus glacialis and Calanus hyperboreus exposed to phenanthrene and benzo[a]pyrene
(Journal article; Peer reviewed, 2022)Arctic and sub-arctic pelagic organisms can be exposed to effluents and spills from offshore petroleum-related activities and thus it is important to understand how they respond to crude oil related contaminants such as ... -
Transcriptome responses in polar cod (Boreogadus saida) liver slice culture exposed to benzo[a]pyrene and ethynylestradiol: insights into anti-estrogenic effects
(Journal article; Peer reviewed, 2021)Polar cod (Boreogadus saida) is a key species in the arctic marine ecosystem vulnerable to effects of pollution, particularly from petroleum related activities. To facilitate studying the effects of those pollutants, we ... -
Transcriptome sequencing of Atlantic salmon ( Salmo salar L.) notochord prior to development of the vertebrae provides clues to regulation of positional fate, chordoblast lineage and mineralisation
(Peer reviewed; Journal article, 2014-02-19)Background In teleosts such as Atlantic salmon (Salmo salar L.), segmentation and subsequent mineralisation of the notochord during embryonic stages are essential for normal vertebrae formation. However, the molecular ... -
Transcriptome-wide analyses of early immune responses in lumpfish leukocytes upon stimulation with poly(I:C)
(Journal article; Peer reviewed, 2023)Background: Both bacterial and viral diseases are a major threat to farmed fish. As the antiviral immune mechanisms in lumpfish (Cyclopterus lumpus L.) are poorly understood, lumpfish leukocytes were stimulated with ... -
A transcriptomic analysis of diploid and triploid Atlantic salmon lenses with and without cataracts
(Journal article; Peer reviewed, 2020)To avoid negative environmental impacts of escapees and potential inter-breeding with wild populations, the Atlantic salmon farming industry has and continues to extensively test triploid fish that are sterile. However, ... -
Transcriptomic and targeted immune transcript analyses confirm localized skin immune responses in Atlantic salmon towards the salmon louse
(Journal article; Peer reviewed, 2023)Atlantic salmon (Salmo salar) are highly susceptible to infestations with the ectoparasite Lepeophtheirus salmonis, the salmon louse. Infestations elicit an immune response in the fish, but the response does not lead to ... -
Transcriptomic comparison of communally reared wild, domesticated and hybrid Atlantic salmon fry under stress and control conditions
(Journal article; Peer reviewed, 2020)Background Domestication is the process by which organisms become adapted to the human-controlled environment. Since the selection pressures that act upon cultured and natural populations differ, adaptations that favour ... -
Transcriptomic profiling of Methylococcus capsulatus (Bath)during growth with two different methane monooxygenases
(Peer reviewed; Journal article, 2016-04)Methylococcus capsulatus (Bath) is a methanotroph that possesses both a membrane-embedded (pMMO) and a soluble methane monooxygenase (sMMO). The expression of these two MMO's is tightly controlled by the availability of ... -
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 ... -
Transduser med stabil åpningsvinkel over et stort frekvensområde. Design, konstruksjon og eksperimentelle målinger
(Master thesis, 2009-11-14)Denne oppgaven tar sikte på å finne en mulig transduserkonstruksjon hvis hensikt er å lette arbeidet ved klassifisering av fiskesorter. Mer vil bli sagt om bakgrunn og motivasjon, men hovedmålet i denne oppgaven er å lage ... -
Transfer entropy computation using the Perron-Frobenius operator
(Peer reviewed; Journal article, 2019)We propose a method for computing the transfer entropy between time series using Ulam's approximation of the Perron-Frobenius (transfer) operator associated with the map generating the dynamics. Our method differs from ... -
Transferring model structures to operads
(Master thesis, 2023-06-01)The thesis defines symmetric operads in some symmetric monoidal category, and gives sufficient conditions for there to be a model category structure on them. -

Transgressive development of coal-bearing coastal plain to shallow marine setting in a flexural compressional basin, Paleocene, Svalbard, Arctic Norway
(Doctoral thesis, 2008-09-08)The most extensive Paleogene succession on Svalbard, in the Arctic north of Norway, is found in the Central Tertiary Basin of Spitsbergen. It consists of a clastic basin fill of mudstone, sandstone, coal and rare conglomerate ... -
Transient Deep Ocean Cooling in the Eastern Equatorial Pacific Ocean at the Eocene-Oligocene Transition
(Journal article; Peer reviewed, 2023)At the Eocene-Oligocene Transition (EOT), approximately 34 million years ago, Earth abruptly transitioned to a climate state sufficiently cool for Antarctica to sustain large ice sheets for the first time in tens to hundreds ... -
Transient high latitude geomagnetic response to rapid increases in solar wind dynamic pressure
(Journal article; Peer reviewed, 2022-08-16)Rapid changes in solar wind dynamic pressure can produce a transient geomagnetic response in the high latitude ionosphere. In this study we carry out a superposed epoch analysis of the geomagnetic response based on 2,058 ... -
Transient Increase in Arctic Deep-Water Formation and Ocean Circulation under Sea Ice Retreat
(Journal article; Peer reviewed, 2021)While a rapid sea ice retreat in the Arctic has become ubiquitous, the potential weakening of the Atlantic meridional overturning circulation (AMOC) in response to global warming is still under debate. As deep mixing occurs ... -
Transient landscape and stratigraphic responses to drainage integration in the actively extending central Italian Apennines
(Journal article; Peer reviewed, 2020)Drainage networks in continental rifts are generally reported as dynamic features that produce transitions between endorheic and exorheic conditions. While this is of major importance for landscape development, sediment ... -
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 ...
