Theoretical and experimental studies of Atlantic cod (Gadus morhua L.) egg buoyancy within a metapopulation framework
(Doctoral thesis, 2012-11-02)Marine fishes are subdivided into genetically separated units at various geographical scales. The mechanisms contributing to distinct populations may include year-round site fidelity or natal homing of juvenile and adult ... -
Thermal plasticity in farmed, wild and hybrid Atlantic salmon during early development: Has domestication caused divergence in low temperature tolerance?
(Peer reviewed; Journal article, 2016-02-16)Background: In the past three decades, millions of domesticated Atlantic salmon Salmo salar L. have escaped from farms into the wild. Their offspring display reduced survival in the natural environment, which demonstrates ... -
Thermal stratification influences maturation and timing of spawning in a local Clupea harengus population
(Peer reviewed; Journal article, 2013) -
Thermal transgenerational effects remain after two generations
(Journal article; Peer reviewed, 2020)Transgenerational plasticity (TGP) is increasingly recognized as a mechanism by which organisms can respond to environments that change across generations. Although recent empirical and theoretical studies have explored ... -
Thermococcus bergensis sp. nov., a Novel Hyperthermophilic Starch-Degrading Archaeon
(Journal article; Peer reviewed, 2021)A novel hyperthermophilic archaeon, termed strain T7324T, was isolated from a mixed sulfate-reducing consortium recovered from hot water produced from a deep North Sea oil reservoir. The isolate is a strict anaerobic ... -
Thermoplasma acidophilum Cdc6 protein stimulates MCM helicase activity by regulating its ATPase activity
(Peer reviewed; Journal article, 2008-08-30)The minichromosome maintenance (MCM) proteins are thought to function as the replicative helicases in archaea. In most archaeal species studied, the interaction between MCM and the initiator protein, Cdc6, inhibits helicase ... -
Think globally, measure locally: The MIREN standardized protocol for monitoring plant species distributions along elevation gradients
(Journal article; Peer reviewed, 2022)Climate change and other global change drivers threaten plant diversity in mountains worldwide. A widely documented response to such environmental modifications is for plant species to change their elevational ranges. Range ... -
Three decades of environmental change studies at alpine Finse, Norway: climate trends and responses across ecological scales
(Journal article; Peer reviewed, 2022)The International Tundra Experiment (ITEX) was established to understand how environmental change impacts Arctic and alpine ecosystems. The success of the ITEX network has allowed for several important across-site syntheses, ... -
Three-dimensional zooplankton distributions seen through the lens of fish in the Barents Sea
(Doctoral thesis, 2019-04-08)My aim with this dissertation is to enhance our knowledge of food availability and foraging opportunities for planktivorous fish over the Barents Sea bathymetry. The Barents Sea is a highly productive sub-Arcic shelf sea ... -
Thyasira ockelmanni (Mollusca: Bivalvia: Veneroidea), A new species of Thyasiridae from the Norwegian Sea
(Peer reviewed; Journal article, 2010)A new species of Thyasiridae, Thyasira ockelmanni n.sp. is described from the abyssal depths of the Norwegian Sea. The generic assignment is tentative and possible alternatives are discussed. The new species has some ... -
The thymus and T-cell ontogeny in ballan wrasse (Labrus bergylta) is nutritionally modelled
(Journal article; Peer reviewed, 2023-05-01)Marine fish larvae often experience high mortality unrelated to predation during early life stages, and farmed ballan wrasse (Labrus bergylta) is no exception. Knowing when the adaptive immune system is developed and fully ... -
Tidleg utvikling av svømmeblæra hjå torskelarvar (Gadus morhua L.) frå intensivt oppdrett
(Master thesis, 2005) -
Time series covering up to four decades reveals major changes and drivers of marine growth and proportion of repeat spawners in an Atlantic salmon population
(Journal article; Peer reviewed, 2022)Wild Atlantic salmon populations have declined in many regions and are affected by diverse natural and anthropogenic factors. To facilitate management guidelines, precise knowledge of mechanisms driving population changes ... -
Time to better integrate paleoecological research infrastructures with neoecology to improve understanding of biodiversity long-term dynamics and to inform future conservation
(Journal article; Peer reviewed, 2021)Anthropogenic pressures are causing a global decline in biodiversity. Successful attempts at biodiversity conservation requires an understanding of biodiversity patterns as well as the drivers and processes that determine ... -
Time-lapse characterization of hydrothermal seawater and microbial interactions with basaltic tephra at Surtsey volcano
(Peer reviewed; Journal article, 2015-12-17)A new International Continental Drilling Program (ICDP) project will drill through the 50-year-old edifice of Surtsey Volcano, the youngest of the Vestmannaeyjar Islands along the south coast of Iceland, to perform ... -
Timeline of Epigenetic Changes Induced by Ethanol (EtOH) in HepG2 and HL60
(Master thesis, 2019-12-14) -
Timing and selectivity of mortality in reared Atlantic cod revealed by otolith analysis
(Peer reviewed; Journal article, 2010-11-03)In juvenile fish production, large samples of known-aged material can be sampled at pre-determined time intervals from the same population. This enables an accurate determination of size-selective mortality by means of ... -
Timing is everything: Fishing-season placement may represent the most important angling-induced evolutionary pressure on Atlantic salmon populations
(Peer reviewed; Journal article, 2017)Fisheries-induced evolution can change the trajectory of wild fish populations by selectively targeting certain phenotypes. For important fish species like Atlantic salmon, this could have large implications for their ... -
Timing of Calanus finmarchicus diapause in stochastic environments
(Journal article; Peer reviewed, 2021)In environments with strong seasonality, many herbivorous zooplankton remain active only during the productive season and undergo a period of inactivity and suppressed development termed ‘diapause’ during the unproductive ... -
Tissue tropism and non-lethal detection of Nucleospora cyclopteri (Microsporidia) in lumpfish (Cyclopterus lumpus L.)
(Master thesis, 2018-06-13)In the present study, wild-caught mature lumpfish (Cyclopterus lumpus) from a brood fish fishery in Norway were examined for the microsporidian parasite Nucleospora cyclopteri. This was done in order to reveal the tissue ...
