Towards more efficient longline fisheries: fish feeding behaviour, bait characteristics and development of alternative baits
(Peer reviewed; Journal article, 2014-12)Better knowledge of food search behavior in fish is essential for studies that aim to improve longline fishing, particularly through bait development. This review provides an overview of our understanding of how fish detect ... -
Toxicity assessment of urban marine sediments from Western Norway using a battery of stress-activated receptors and cell-based bioassays from fish
(Journal article; Peer reviewed, 2021)A luciferase reporter gene-based bioassay battery consisting of stress-activated receptors from fish, complemented with traditional fish cell-based bioassays, were used to assess the toxicity of marine sediment samples ... -
Tracing recovery from acidification in the Western Norwegian nausta watershed
(Journal article; Peer reviewed, 2003)A novel method, redundancy analysis (RDA), has been used to examine whether chemical recovery from acidification in the western Norwegian Nausta watershed produces detectable recovery within the community structure of the ... -
Tracing simultaneous cadmium accumulation from different uptake routes in brown crab Cancer pagurus by the use of stable isotopes
(Peer reviewed; Journal article, 2018-05-24)High concentrations of cadmium in brown crab are an issue of food safety, and large variations between different areas have been found. To investigate the relative importance of dietary and aqueous uptake regarding the ... -
Tracking freshwater browning and coastal water darkening from boreal forests to the Arctic Ocean
(Journal article; Peer reviewed, 2023)The forest cover of Northern Europe has been steadily expanding during the last 120 years. More terrestrial vegetation and carbon fixation leads to more export to surface waters. This may cause freshwater browning, as more ... -
Tracking integrated ecosystem assessments in the ICES network: a social network analysis of the ICES expert groups
(Journal article; Peer reviewed, 2023)The advice the International Council for the Exploration of the Sea (ICES) provides to its member countries is crucial for the sustainable management of shared marine resources, and the conservation of relevant marine ... -
Tracking oocyte development and the timing of skipped spawning for north-east Arctic haddock (Melanogrammus aeglefinus)
(Journal article; Peer reviewed, 2022)The present study tracked oocyte development over 9 months and noted incidences of ‘skipping’, i.e., adults terminating their upcoming reproductive cycle, in field-caught north-east Arctic (NEA) haddock (Melanogrammus ... -
Tracking the time course of reproductive events in the Northeast Arctic haddock (Melanogrammus aeglefinus)
(Master thesis, 2021-06-15)An important objective of fisheries management is to ensure harvest rates that allows the population to maintain its reproductive potential over time. Reproductive biology is thus of key importance when managing a fish ... -
Trade-off between mate choice speed and decision accuracy under mating competition in female sand gobies
(Journal article; Peer reviewed, 2020)Variation in female mating performance can affect the direction and rate of evolution through sexual selection. The social environment determines the availability of mates and the competitive situation, and hence can ... -
Trade-offs between growth and reproduction in wild Atlantic cod
(Peer reviewed; Journal article, 2014-04-08)Animals partition and trade off their resources between competing needs such as growth, maintenance, and reproduction. Over a lifetime, allocation strategies should result in distinct trajectories for growth, survival, and ... -
Traditional nomadic tending of trees in the Red Sea Hills
(Peer reviewed; Journal article, 2014-04-12)There are recurring questions about the ecological sustainability of indigenous resource management and what traditional ecological knowledge and rationale underlie such practices. Pastoral nomads from the Hadandawa, Amar ... -
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 ...
