The vgll3 Locus Controls Age at Maturity in Wild and Domesticated Atlantic Salmon(Salmo salar L.) Males
(Journal article; Peer reviewed, 2015-11-09)Wild and domesticated Atlantic salmon males display large variation for sea age at sexual maturation, which varies between 1–5 years. Previous studies have uncovered a genetic predisposition for variation of age at maturity ... -
The β-oxidation pathway is downregulated during diapause termination in Calanus copepods
(Journal article; Peer reviewed, 2019)Calanus copepods are keystone species in marine ecosystems, mainly due to their high lipid content, which is a nutritious food source for e.g. juvenile fish. Accumulated lipids are catabolized to meet energy requirements ... -
The “Discard Ban Package”: Experiences in efforts to improve the exploitation patterns in Norwegian fisheries
(Journal article; Peer reviewed, 2015-01-09)A source to long-term increased catches and profitability for the fishing fleet is the reduction of discards and improvements in exploitation patterns. This article details the development of Norwegian regulatory measures ... -
Thermal dynamics of ovarian maturation in Atlantic cod (Gadus Morhua)
(Journal article; Peer reviewed, 2010-03)The timing and success of spawning in marine fish are of fundamental importance to population persistence and distribution and, for commercial species, sustainability. Their physiological processes of reproduction are ... -
Thermal injuries in Atlantic salmon in a pilot Laboratory trial
(Peer reviewed; Journal article, 2019)Thermal delousing is a new method for removing sea lice from farmed Atlantic salmon (Salmo salar L). We investigated thermally-related tissue injuries in Atlantic salmon in a pilot laboratory trial to describe the acute ... -
Thermal niche of Atlantic cod Gadus morhua: limits, tolerance and optima
(Journal article; Peer reviewed, 2010)Recent studies in the marine environment have suggested that the limited phenotypic plasticity of cold-adapted species such as Atlantic cod Gadus morhua L. will cause distributions to shift toward the poles in response to ... -
Thermal plasticity in farmed, wild and hybrid Atlantic salmon during early development: Has domestication caused divergence in low temperature tolerance?
(Journal article; Peer reviewed, 2016-02-16) -
Thermal variability induces sex-specific morphometric changes in zebrafish (Danio rerio)
(Peer reviewed; Journal article, 2023)In nature, organisms are exposed to variable environmental conditions that impact their performance and fitness. Despite the ubiquity of environmental variability, substantial knowledge gaps in our understanding of organismal ... -
Thin and transient meltwater layers and false bottoms in the Arctic sea ice pack-Recent insights on these historically overlooked features
(Peer reviewed; Journal article, 2023)The rapid melt of snow and sea ice during the Arctic summer provides a significant source of low-salinity meltwater to the surface ocean on the local scale. The accumulation of this meltwater on, under, and around sea ice ... -
Thirty years of nutrients and biogeochemistry in the Norwegian, Greenland and Iceland Seas, 1990-2019
(Peer reviewed; Journal article, 2023)This dataset contains biogeochemical samples analyzed by the Plankton Chemistry Laboratory at the Institute of Marine Research (IMR), from the Norwegian, Greenland and Iceland Seas. Number of surveys and stations have ... -
Three chromosomal rearrangements promote genomic divergence between migratory and stationary ecotypes of Atlantic cod
(Journal article; Peer reviewed, 2016-03-17)Identification of genome-wide patterns of divergence provides insight on how genomes are influenced by selection and can reveal the potential for local adaptation in spatially structured populations. In Atlantic cod – ... -
Three decades of change in the Skagerrak coastal ecosystem, shaped by eutrophication and coastal darkening
(Peer reviewed; Journal article, 2023)Global coastal ecosystems are under accelerating pressure from human activities and climate change. In this study we explore a long-term time series (mostly 1990–2016) from major Norwegian rivers, together with coastal ... -
Three Decades of Farmed Escapees in the Wild: A Spatio- Temporal Analysis of Atlantic Salmon Population Genetic Structure throughout Norway
(Journal article; Peer reviewed, 2012-08-15)Each year, hundreds of thousands of domesticated farmed Atlantic salmon escape into the wild. In Norway, which is the world’s largest commercial producer, many native Atlantic salmon populations have experienced large ... -
Three new goatfishes of the genus Upeneus (Mullidae) from the Indo-Pacific, with a redescription of colour patterns in U. margarethae
(Journal article; Peer reviewed, 2019)For the goatfish genus Upeneus Cuvier 1829 (Mullidae), a new taxonomic species group called the “margarethae group” is established which can be distinguished from the six species of the most similar “tragula group” by a ... -
Three new goatfishes of the genus Upeneus from the Eastern Indian Ocean and Western Pacific, with an updated taxonomic account for U. itoui (Mullidae: japonicus-species group)
(Peer reviewed; Journal article, 2021)Coastal marine fish diversity from E India and Indonesia to S Japan is still insufficiently investigated. Of the 42 species of goatfishes (Mullidae) recorded from this area, 12 were described only since 2010 and ten of ... -
Three-dimensional maturation reaction norms for North Sea plaice
(Journal article; Peer reviewed, 2007-03-26)Probabilistic maturation reaction norms (PMRNs) with up to 3 explanatory dimensions were estimated for female North Sea plaice Pleuronectes platessa. The 3-dimensional PMRNs reported here (1) are the first to be obtained ... -
The three-dimensional prey field of the northern krill, Meganyctiphanes norvegica, and the escape responses of their copepod prey
(Journal article; Peer reviewed, 2010-02-24)In the north Atlantic, Meganyctiphanes norvegica feeds predominantly on copepods, including Calanus spp. To quantify its perceptual field for prey, and the sensory systems underlying prey detection, the responses of tethered ... -
The thymus and T-cell ontogeny in ballan wrasse (Labrus bergylta) is nutritionally modelled
(Peer reviewed; Journal article, 2023)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 ... -
Thyroid function and urinary concentrations of iodine, selenium, and arsenic in vegans, lacto-ovo vegetarians and pescatarians
(Peer reviewed; Journal article, 2023)Populations following a plant-based diet may be at particular risk of thyroid dysfunction due to low iodine and selenium intakes. The main purpose was to assess thyroid function and urinary concentration of iodine, selenium, ...
