(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 ... -
Caligus elongatus and other sea lice of the genus Caligus as parasites of farmed salmonids: A review
(Journal article; Peer reviewed, 2020)This review was prompted by reports of unusually large numbers of sea lice tentatively identified as Caligus elongatus infesting farmed salmon in northern Norway. Following a brief introduction to the sea lice problem in ... -
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 bryophyte groups increase functional resolution in tundra ecosystems?
(Journal article; Peer reviewed, 2021)The relative contribution of bryophytes to plant diversity, primary productivity, and ecosystem functioning increases towards colder climates. Bryophytes respond to environmental changes at the species level, but because ... -
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 ... -
“Candidatus Ethanoperedens,” a thermophilic genus of archaea mediating the anaerobic oxidation of ethane
(Journal article; Peer reviewed, 2020)Cold seeps and hydrothermal vents deliver large amounts of methane and other gaseous alkanes into marine surface sediments. Consortia of archaea and partner bacteria thrive on the oxidation of these alkanes and its coupling ... -
Captive breeding of European freshwater mussels as aconservation tool: A review
(Journal article; Peer reviewed, 2023)1. Freshwater mussels are declining throughout their range. Their importantecological functions along with insufficient levels of natural recruitment haveprompted captive breeding for population augmentation and questions ... -
