Biochemical composition of Rhodomonas baltica as a function of the dilution rate during steady rate of growth
(Master thesis, 2013)The algae Rhodomonas baltica, Karsten was cultured in Guillard f-medium with the phosphate concentration reduced to 5 µmol/L. The cultures were diluted at seven different dilution rates corresponding approximately to growth ... -
Biodegradation of oil spill dispersant surfactants in cold seawater
(Journal article; Peer reviewed, 2018)While biodegradation of chemically dispersed oil has been well documented, only a few studies have focused on the degradation of the dispersant compounds themselves. The objective of this study was to determine the ... -
Biodegradation-mediated alterations in acute toxicity of water-accommodated fraction and single crude oil components in cold seawater
(Journal article; Peer reviewed, 2018)Hydrocarbon biodegradation may be slower in cold Arctic than in temperate seawater, and this will affect the toxicity time window of the hydrocarbons. In this study, the acute toxicities of water-soluble phases of ... -
Biodiversity dynamics in urban areas under changing land-uses
(Doctoral theses at NTNU;2021:107, Doctoral thesis, 2021)Ecology goes to town Urbanisation is increasing worldwide, but as urban expansion inevitably happens at the cost of other ecosystems, understanding how this will affect biodiversity is crucial. Especially if we wish to ... -
Biodiversity of benthic invertebrates in regulated and unregulated lakes
(Master thesis, 2024)Menneskelige påvirkninger på økosystemer, særlig endring i arealbruk og tilknyttet habitatødeleggelse og fragmentering, er i ferd med å skape globale tap i biodiversitet. Ferskvannssystemer er spesielt utsatt, siden de har ... -
Biodiversity Revisited: Impacts of Hydropower Activities on Aquatic Insect Fauna on Decadal Timescales
(Master thesis, 2022)Økosystemer globalt er under stort press fra menneskelige aktiviteter, og ferskvannsøkosystemer er spesielt sårbare. En viktig kilde til påvirkning av ferskvann er vannkraft, som påvirker biologisk mangfold gjennom ... -
Biofouling in the Norwegian Salmon Farming Industry
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:320, Doctoral thesis, 2013)Biofouling, the unwanted growth of organisms on submerged artificial surfaces, is ubiquitous in the marine environment and a particular problem in the salmon farming industry. In Norway, one of the most common and problematic ... -
Biofouling on salmon pen nets and cleaner fish shelters does not harbor planktonic stages of sea lice
(Peer reviewed; Journal article, 2020)The objective of the current study was to determine the extent to which planktonic sea lice (Lepeophtheirus salmonis Krøyer, 1838 and Caligus elongatus Nordmann, 1832) were present in the biofouling on open-sea net pens ... -
BioGateway: A Semantic Systems Biology Tool for the Life Sciences
(Journal article; Peer reviewed, 2009)Background: Life scientists need help in coping with the plethora of fast growing and scattered knowledge resources. Ideally, this knowledge should be integrated in a form that allows them to pose complex questions that ... -
Biokonvertering av tungolje kombinert med løsemiddelekstraksjon
(Master thesis, 2011)Bitumen er en svært viskøs råolje som er vanskelig å utvinne. Selv om verdens tungoljereserver er store er det utvunnet svært lite tungolje ved bruk av tradisjonelle utvinningsmetoder. Behovet for drivstoff øker behovet ... -
Biologiske undersøkelser i Altaelva 1981-2006. Oppsummering av kraftreguleringens konsekvenser for laksebestanden
(NINA rapport;, Research report, 2007)Nøkkelord : kraftregulering, Altaelva, Finnmark, laks, laksefangster, ungfisktetthet, vinterdødelighet, smoltproduksjon, bunnfauna, begroing -
Biologiske undersøkelser i Altaelva 2004
(NINA-rapport;43, Research report, 2005)Altaelva er ei av Norges beste elver for sportsfiske etter laks. Elva har en storvokst laksestamme, og en unik kultur og historie knyttet til laksefisket. Stortinget vedtok å utbygge og regulere elva for kraftproduksjon i ... -
Bioluminescence as an ecological factor during high Arctic polar night
(Journal article; Peer reviewed, 2016)Bioluminescence commonly influences pelagic trophic interactions at mesopelagic depths. Here we characterize a vertical gradient in structure of a generally low species diversity bioluminescent community at shallower ... -
Biomarkers of oxidative stress in Calanus finmarchicus exposed to a water accommodated fraction of a naphthenic North Atlantic crude oil
(Master thesis, 2018)Calanus finmarchicus is an ecologically important species in the North, Norwegian and Barents Seas, periodically constituting up to 90% of the standing stock of zooplankton. Due to continued development of areas for oil ... -
Biomonitoring of rare earth elements in Southern Norway: Distribution, fractionation, and accumulation patterns in the marine bivalves Mytilus spp. and Tapes spp.
(Peer reviewed; Journal article, 2023)Growing extraction and usage of rare earth elements and yttrium (REY) for medical and industrial applications has resulted in increased discharges into the marine environment. Using Mytilus spp. Mussels and Tapes spp. clams ... -
Biomorphogenic Feedbacks and the Spatial Organization of a Dominant Grass Steer Dune Development
(Peer reviewed; Journal article, 2021)Nature-based solutions to mitigate the impact of future climate change depend on restoring biological diversity and natural processes. Coastal foredunes represent the most important natural flood barriers along coastlines ... -
Bionic flapping pectoral fin with controllable spatial deformation
(Journal article; Peer reviewed, 2019)This paper presents the design of a bionic pectoral fin with fin rays driven by multi-joint mechanism. Inspired by the cownose ray, the bionic pectoral fin is modeled and simplified based on the key structure and movement ... -
Bioremediation of aquaculture sludge by cultivation of Hediste diversicolor (O.F. Müller, 1776)
(Master thesis, 2021)Oppdrett av Atlantisk laks (Salmo salar) produserer store mengder organisk partikulært avfall. I motsetning til åpne havmerder, samles det partikulære avfallet som slam ved landbaserte oppdrettsanlegg. Bioremediering av ... -
