The C-terminal domain of eukaryotic initiation factor 5 promotes start codon recognition by its dynamic interplay with eIF1 and eIF2 beta
(Peer reviewed; Journal article, 2012-06-28)Recognition of the proper start codon on mRNAs is essential for protein synthesis, which requires scanning and involves eukaryotic initiation factors (eIFs) eIF1, eIF1A, eIF2, and eIF5. The carboxyl terminal domain (CTD) ... -
Ca^2+-signalling in C. intestinalis notochord cells during embryonic development
(Master thesis, 2018-05-10)C. intestinalis notochord is an essential structure during embryonic development, conveying position and fate information, in addition to serving as a structural support and enabling locomotion during larval stage. Researchers ... -
Cadmium in Brown Crab Cancer pagurus in Norwegian Waters
(Doctoral thesis, 2018-05-23)The Brown crab Cancer pagurus is appreciated as seafood and its fishery is of importance in several European countries. However, findings of high levels of cadmium have increased concern about food safety, and spatial ... -
Cadmium in brown crab Cancer pagurus. Effects of location, season, cooking and multiple physiological factors and consequences for food safety
(Journal article; Peer reviewed, 2020)Brown crab Cancer pagurus is appreciated as seafood in several European countries. However, cadmium levels in crabs can be elevated and their consumption may pose a hazard for human health. To assess if cadmium poses a ... -
Cadmium in the shore crab Carcinus maenas along the Norwegian coast: geographical and seasonal variation and correlation to physiological parameters
(Peer reviewed; Journal article, 2018-04)Previously, high concentrations of cadmium have been found in the hepatopancreas of the edible or brown crab (Cancer pagurus) sampled from positions north of about 67° N, compared to regions further south along the Norwegian ... -
CAGEr: Precise TSS data retrieval and high-resolution promoterome mining for integrative analyses
(Peer reviewed; Journal article, 2015)Cap analysis of gene expression (CAGE) is a high-throughput method for transcriptome analysis that provides a single base-pair resolution map of transcription start sites (TSS) and their relative usage. Despite their high ... -
Can an old alien benefit from rising ocean temperatures? An experimental and field study on the growth and local distribution of Codium fragile subsp. fragile (Chlorophyta)
(Peer reviewed; Journal article, 2017-06)Codium fragile subsp. fragile (hereafter C. fragile) is a widespread non-native chlorophyte. Experimental and observational approaches were used to examine the influence of temperature on its growth and local distribution ... -
Can enrichment improve the post-release survival of hatchery-reared Atlantic salmon fry (Salmo salar)? – A field experiment
(Master thesis, 2018-06-26)Release of captive-reared fish to supplement reduced, wild populations has become a common tool for conservation and management. Such attempted population enhancements have, however, had limited success, and several previous ... -
Can fresh water diets influence recovery in Atlantic salmon post-smolts after SAV3 challenge in sea water?
(Master thesis, 2020-07-08)Pankreas sykdom (PD) forårsaket av salmonid alfavirus (SAV) er en betydelig utfordring i norsk oppdrettsnæring. Å undersøke om forskjeller i fôrsammensetning før overføring til sjøvann kan påvirke sykdommens progresjon og ... -
Can less be more? Effects of reduced frequency of surveys and stock assessments
(Peer reviewed; Journal article, 2016)Uncertain and inaccurate estimates are a prevailing problem in stock assessment, despite increasingly sophisticated estimation methods and substantial usage of scientific and financial resources. Annual scientific surveys ... -
Can snow depth be used to predict the distribution of the high Arctic aphid Acyrthosiphon svalbardicum (Hemiptera: Aphididae) on Spitsbergen?
(Peer reviewed; Journal article, 2011-10-13)Background: The Svalbard endemic aphid Acyrthosiphon svalbardicum (Heikinheimo, 1968) is host specific to Dryas octopetala L. ssp octopetala (Rosaceae). It has been hypothesized that the aphid is present on those areas ... -
Carbohydrate metabolism during vertebrate appendage regeneration: What is its role? How is it regulated? A postulation that regenerating vertebrate appendages facilitate glycolytic and pentose phosphate pathways to fuel macromolecule biosynthesis
(Peer reviewed; Journal article, 2014-01)We recently examined gene expression during Xenopus tadpole tail appendage regeneration and found that carbohydrate regulatory genes were dramatically altered during the regeneration process. In this essay, we speculate ... -
Carbon Bioavailability in a High Arctic Fjord Influenced by Glacial Meltwater, NE Greenland
(Peer reviewed; Journal article, 2017-06-08)The land-to-ocean flux of organic carbon is increasing in glacierized regions in response to increasing temperatures in the Arctic (Hood et al., 2015). In order to understand the response of the coastal ecosystem metabolism ... -
CarboSchools - et utvannet klimaprosjekt eller et forbilde for gode feltstudier i biologi. En casestudie av en biologiklasses erfaringer og utbytte knyttet til CarboSchools prosjektet.
(Master thesis, 2010-12-20)Sammendrag Internasjonale undersøkelser som TIMMS og PISA, samt søkertallene til høyere utdannelser har vist en negativ utvikling for realfagene både kunnskapsmessig og rekrutteringsmessig i løpet av 90-tallet og begynnelsen ... -
Carnivorous sponges of the Atlantic and Arctic Oceans. Phylogeny, taxonomy, distribution and microbial associations of the Cladorhizidae (Demospongiae, Poecilosclerida)
(Doctoral thesis, 2016-11-29)The sponges (phylum Porifera) are defined by the presence of an aquiferous system in which choanoflagellate cells create a current and filter water flowing through the sponge body. The carnivorous sponges represent the ... -
A case study of biofilter activation and microbial nitrification in a marine recirculation aquaculture system for rearing Atlantic salmon (Salmo salar L.)
(Peer reviewed; Journal article, 2020-09)Marine recirculation aquaculture system (RAS) is a prominent technology within fish farming. However, the nitrifying bacteria in the biofilter have low growth rates, which can make the biofilter activation a long and ... -
Catastrophic dynamics limit Atlantic cod recovery
