Egg buoyancy variability in local populations of Atlantic cod (Gadus morhua)
(Peer reviewed; Journal article, 2012)Previous studies have found strong evidences for Atlantic cod (Gadus morhua) egg retention in fjords, which are caused by the combination of vertical salinity structure, estuarine circulation, and egg specific gravity, ... -
Egg size and density estimates for three gadoids in Icelandic waters and their implications for the vertical distribution of eggs along a stratified water column
(Journal article; Peer reviewed, 2020)The vertical distribution of fish eggs can have important consequences for recruitment through its influence on dispersal trajectories and thus connectivity between spawning and nursery locations. Egg density and size are ... -
Eight decades of adaptive changes in herring reproductive investment: the joint effect of environment and exploitation
(Journal article; Peer reviewed, 2021)Reproductive investment is a central trait for population dynamics and productivity. Fishing and environmental variations are major drivers affecting population structure, dynamics, and adaptation of life-history and ... -
Eight Recommendations to Promote Effective Study Habits for Biology Students Enrolled in Online Courses
(Journal article; Peer reviewed, 2022)To achieve meaningful learning experiences in online classrooms, students must become self-regulated learners through the development of effective study habits. Currently, there is no set of recommendations to promote study ... -
Eksperimentell eksponering av laksefiskyngel for salmonid alphavirus (SAV3) – Sammenligning av mottakelighet og konsekvens hos brunørret (Salmo trutta L.) og atlantisk laks (Salmo salar L.)
(Master thesis, 2018-12)Salmonid alfavirus (SAV) forårsaker pankreassyke (PD) hos laksefisk i oppdrett. PD er utbredt i Norge og var den mest rapporterte virussykdommen i 2017. Det er en bekymring at rømt oppdrettsfisk som er infisert med viruset ... -
Eksperimentell smitte av grønngylt, Symphodus melops, med V.tapetis - isolatene CECT 4600, LP2 og NRP45
(Master thesis, 2011-08-30)The use of wrasse (Labridae) as cleanerfish in salmonid aquaculture is the only method for removal of salmon lice that does not have any negative impact on the environment. The use of wild-caught wrasse has increased during ... -
Electrical Stunning of Edible Crabs
(Research report, 2013)In the project StunCrab, kindly supported by the Norwegian Research Council, SeaSide AS, Hitramat AS and Nofima has successfully developed and implemented electrical stunning of edible crab. The research has shown highest ... -
Elemental composition of illicia and otoliths and their potential application to age validation in white anglerfish (Lophius piscatorius linnaeus, 1758)
(Journal article; Peer reviewed, 2021)The incorporation of trace elements into the calcified structures of fish can vary seasonally. Interpretation of these seasonal signals can provide information about fish age. This approach offers great promise for objectively ... -
Elevated sea temperature combined with dietary methionine levels affect feed intake and appetite-related neuropeptide expression in the brains of juvenile cobia (Rachycentron canadum)
(Journal article; Peer reviewed, 2023-07-04)This study aimed to determine the impact of elevated temperature combined with different levels of dietary methionine concentrations on feed intake (FI) and brain expression of selected neuropeptides and one receptor ... -
ELM: the status of the 2010 eukaryotic linear motif resource
(Peer reviewed; Journal article, 2009-11-17)Linear motifs are short segments of multidomain proteins that provide regulatory functions independently of protein tertiary structure. Much of intracellular signalling passes through protein modifications at linear motifs. ... -
Emergence of games from ecological trade-offs: longevity changes strategies for extra-pair mating in birds
(Journal article; Peer reviewed, 2023)Each member of a breeding pair benefits if the other does more of the parental investment, so there is scope for behaviours that can be interpreted as both cooperative and competitive games between males and females. ... -
Emerging interaction patterns in the Emiliania huxleyi-EhV system
(Journal article, 2017-03-22)Viruses are thought to be fundamental in driving microbial diversity in the oceanic planktonic realm. That role and associated emerging infection patterns remain particularly elusive for eukaryotic phytoplankton and their ... -
The emotion system promotes diversity and evolvability
(Peer reviewed; Journal article, 2014-08-06)Studies on the relationship between the optimal phenotype and its environment have had limited focus on genotype-to-phenotype pathways and their evolutionary consequences. Here, we study how multi-layered trait architecture ... -
Empirical Support for Optimal Virulence in a Castrating Parasite
(Peer reviewed; Journal article, 2006-05-30)The trade-off hypothesis for the evolution of virulence predicts that parasite transmission stage production and host exploitation are balanced such that lifetime transmission success (LTS) is maximised. However, the ... -
En analyse av læreverk i biologi sett i lys av Læreplanverket for Kunnskapsløftet
(Master thesis, 2015-01-30)Den kompetanseorientere læreplanen, LK06, og lærebokens sentrale rolle i undervisningen gav utspring til denne masteroppgaven. Her presenteres resultatene av en analyse utført på to læreverk i biologi, med fokus på hvordan ... -
En tverrfaglig tilnærming til ulike perspektiver på verdier og verdisetting av to kulturlandskaper på Osterøy
(Master thesis, 2016-10-03)Biodiversitet blir brukt som et numerisk mål på verdisetting av natur under vurdering om bevaring av ulike naturtyper og kulturlandskap i naturvernforvaltningen i Norge. I forskning er biodiversitet et begrep med mange ... -
Endometrial cancer cells exhibit high expression of p110β and its selective inhibition induces variable responses on PI3K signaling, cell survival and proliferation
(Peer reviewed; Journal article, 2017-12-16)PTEN loss and constitutive activation of the class I phosphoinositide 3-kinase (PI3K) pathway are key drivers of endometrial tumorigenesis. In some cancer types, PTEN-deficient tumors are reliant on class I PI3K p110β ... -
Endoplasmic reticulum stress as a key mechanism in stunted growth of seawater rainbow trout (Oncorhynchus mykiss)
(Journal article; Peer reviewed, 2021)Background Rainbow trout (Oncorhynchus mykiss) is a salmonid species with a complex life-history. Wild populations are naturally divided into freshwater residents and sea-run migrants. Migrants undergo an energy-demanding ... -
