Traditional plant functional groups explain variation in economic but not size‐related traits across the tundra biome
(Peer reviewed; Journal article, 2019-01)Aim : Plant functional groups are widely used in community ecology and earth system modelling to describe trait variation within and across plant communities. However, this approach rests on the assumption that functional ... -
Traditional prescribed burning of coastal heathland provides niches for xerophilous and sun‑loving beetles
(Journal article; Peer reviewed, 2023)In Western Norway, farmers have traditionally used fire as a management tool in coastal heathlands to enhance the fodder quality for livestock. Rotational prescribed burning increases landscape heterogeneity by creating a ... -
Trait-based approaches as ecological time machines: Developing tools for reconstructing long-term variation in ecosystems
(Journal article; Peer reviewed, 2023)Research over the past decade has shown that quantifying spatial variation in ecosystem properties is an effective approach to investigating the effects of environmental change on ecosystems. Yet, current consensus among ... -
Trait-based responses to land use and canopy dynamics modify long-term diversity changes in forest understories
(Journal article; Peer reviewed, 2021)Aim: Land use is the foremost cause of global biodiversity decline, but species do not respond equally to land-use practices. Instead, it is suggested that responses vary with species traits, but long-term data on the ... -
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 ... -
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 ...
