The exorhodopsin and melanopsin systems in the pineal complex and brain at early developmental stages of Atlantic halibut (Hippoglossus hippoglossus)
(Journal article; Peer reviewed, 2014)The complexity of the nonvisual photoreception systems in teleosts has just started to be appreciated, with colocalization of multiple photoreceptor types with unresolved functions. Here we describe an intricate expression ... -
An expanded calibration model for inferring lakewater and air temperatures from fossil chironomid assemblages in northern Fennoscandia
(Peer reviewed; Journal article, 1999)Chironomid-temperature inference models based on an expanded data set of surface-sediment and limnological data from 53 Subarctic lakes in northern Fennoscandia have been developed using eight different numerical techniques, ... -
Expansion of the barnacle Austrominius modestus (Darwin, 1854) (cirripedia, Thoracica, Balanidae) into Scandinavian waters based on collection data and niche distribution modeling
(Journal article; Peer reviewed, 2021)The barnacle Austrominius modestus, native of New Zealand and Australia was introduced to the South of England around 1943 and has since spread to most coastal waters in Western Europe, including the southern North Sea. ... -
Experiment design and bacterial abundance control extracellular H2O2 concentrations during four series of mesocosm experiments
(Journal article; Peer reviewed, 2020)The extracellular concentration of H2O2 in surface aquatic environments is controlled by a balance between photochemical production and the microbial synthesis of catalase and peroxidase enzymes to remove H2O2 from solution. ... -
Experimental challenge of Atlantic salmon Salmo salar using clones of Paramoeba perurans, P. pemaquidensis and Tetramitus sp.
(Journal article; Peer reviewed, 2021)Salmon gill disease in Norway is in most cases associated with a range of different pathogens, stress and environmental factors. Paramoeba perurans and other amoebae have been isolated during such disease outbreaks. Other ... -
Experimental induction of mouthrot in Atlantic salmon smolts using Tenacibaculum maritimum from Western Canada
(Peer reviewed; Journal article, 2018-08)Mouthrot, or bacterial stomatitis, is a disease which mainly affects farmed Atlantic salmon, (Salmo salar, L.), smolts recently transferred into salt water in both British Columbia (BC), Canada, and Washington State, USA. ... -
Experimental parameterisation of principal physics in buoyancy variations of marine teleost eggs
(Peer reviewed; Journal article, 2014-08-14)It is generally accepted that the high buoyancy of pelagic marine eggs is due to substantial influx of water across the cell membrane just before ovulation. Here we further develop the theoretical basis by applying laboratory ... -
Experimental warming differentially affects vegetative and reproductive phenology of tundra plants
(Journal article; Peer reviewed, 2021)Rapid climate warming is altering Arctic and alpine tundra ecosystem structure and function, including shifts in plant phenology. While the advancement of green up and flowering are well-documented, it remains unclear ... -
Exploring balanced harvesting by using an Atlantis ecosystem model for the Nordic and Barents seas
(Journal article; Peer reviewed, 2020)“Balanced Harvesting” (BH) has been suggested as a possible strategy to meet the objectives of the Ecosystem Approach to Fisheries, ensuring a high sustainable yield while maintaining ecosystem structure and function. BH ... -
Exploring balanced harvesting by using an Atlantis ecosystem model for the Nordic and Barents Seas
(Master thesis, 2018-06-20)To meet the objectives of the Ecosystem Approach to Fisheries, “Balanced Harvesting” (BH) has been suggested as a possible strategy to ensure a high sustainable yield while maintaining ecosystem structure and function. BH ... -
Exploring codon adjustment strategies towards Escherichia coli-based production of viral proteins encoded by HTH1, a novel prophage of the marine bacterium Hypnocyclicus thermotrophus
(Journal article; Peer reviewed, 2021)Marine viral sequence space is immense and presents a promising resource for the discovery of new enzymes interesting for research and biotechnology. However, bottlenecks in the functional annotation of viral genes and ... -
Exploring spatio-temporal patterns of palynological changes in Asia during the Holocene
(Journal article; Peer reviewed, 2023-05-05)Historical legacies influence present-day ecosystem composition and dynamics. It is therefore important to understand the long-term dynamics of ecosystems and their properties. Analysis of ecosystem properties during the ... -
Exposure to cold temperatures differentially modulates neural plasticity and stress responses in post-smolt Atlantic salmon (Salmo salar)
(Journal article; Peer reviewed, 2022)The transfer success of farmed post-smolt Atlantic salmon (Salmo salar) to sea-cages rely on neural adaptions to promote stress resilience. As low temperatures impact physiology, this suggests that off-season transfer to ... -
Expression and function of the transcription factor Rx in Nematostella vectensis
(Master thesis, 2023-06-02)The development of the central nervous system is highly studied and a comparatively well understood field of neurogenesis. The fundamental aspects of neurogenesis have however mostly been studied in a select few bilaterian ... -
Expression and localization of the aryl hydrocarbon receptors and cytochrome P450 1A during early development of Atlantic cod (Gadus morhua)
(Journal article; Peer reviewed, 2020)The aryl hydrocarbon receptor (Ahr) is a ligand-activated transcription factor that mediates the toxicity of dioxins and dioxin-like compounds (DLCs) in vertebrates. Two clades of the Ahr family exist in teleosts (Ahr1 and ... -
Expression of visual opsins in the retina of Atlantic salmon (Salmo salar L.) during smoltification
(Master thesis, 2020-06-24)Abstract: The visual system of Atlantic salmon is highly adapted to their migratory and dynamic life-history, where the profound transformational process of smoltification is crucial. The retina contain both rod- and cone ... -
An extensive common‐garden study with domesticated and wild Atlantic salmon in the wild reveals impact on smolt production and shifts in fitness traits
(Peer reviewed; Journal article, 2019-02-19)Interactions between domesticated escapees and wild conspecifics represent a threat to the genetic integrity and fitness of native populations. For Atlantic salmon, the recurrent presence of large numbers of domesticated ... -
Extra-pair mating and evolution of cooperative neighbourhoods
(Peer reviewed; Journal article, 2014-07-02)A striking but unexplained pattern in biology is the promiscuous mating behaviour in socially monogamous species. Although females commonly solicit extra-pair copulations, the adaptive reason has remained elusive. We use ... -
Extra-pair paternity explains cooperation in a bird species
(Journal article; Peer reviewed, 2022)In many social animals, females mate with multiple males, but the adaptive value of female extra-pair mating is not fully understood. Here, we tested whether male pied flycatchers (Ficedula hypoleuca) engaging in extra-pair ...
