Effects of elevated water temperatures and microalgae diet on prosome size, fat sac development, egg production and hatching success in Calanus finmarchicus.
Sæther, Simen (Master thesis, 2021)Raudåta (Calanus finmarchicus, Gunnerus) er en nøkkelart i Barents- og Norskehavet på grunn av sin tallrikhet og betydning knyttet til energioverføring mellom primærprodusenter og kommersielle fiskearter. Slik som mange ... -
Effects of produced water components on the early life stages of Calanus finmarchicus and Calanus hyperboreus reared at different temperatures
Utne, Katarina (Master thesis, 2017)Receding sea ice, as a result global warming, increases the marine access to the petroleum resources in the Arctic. Due to the increasing global energy demand, more oil and gas activity is likely to occur. Petroleum ... -
Effects of produced water on growth and development of Calanus finmarchicus and Calanus hyperboreus early life stages at different temperatures
Jørgensen, Ingrid Kvinge (Master thesis, 2017)The temperature in the Arctic is increasing, which causes the sea ice to retreat. This opens for more offshore activity and longer shipping season for transportation vessels. The Arctic region is thought to contain large ... -
Effekter av Tekstilfibre på den Marine Mikroalgen Isochrysis galbana (T-ISO)
Rogstad, Dina Tevik (Master thesis, 2019)Tekstilmikrofibre (MF) er i økende grad en bekymring i marine økosystemer, ettersom store mengder av MF ender i havet hvert år via avfall og avløpsvann. Til tross for høy persistens og biotilgjengeligheten av MF i marine ... -
Experimental weathering of microplastic under simulated environmental conditions - Method development and characterization of pristine, photodegraded and mechanically weathered microplastic
Hepsø, Marion Olsen (Master thesis, 2018)The aim of this master thesis was to investigate the physico-chemical changes of microplastic (MP) weathered under simulated environmental conditions: floating on the ocean surface and in the intertidal zone. Polyethylene ... -
Modelling the dynamics of growth, development and lipid storage in the marine copepod Calanus finmarchicus
Jager, Tjalling; Salaverria-Zabalegui, Iurgi Imanol; Altin, Dag; Nordtug, Trond; Hansen, Bjørn Henrik (Journal article; Peer reviewed, 2017)Mechanistic models are essential tools for interpreting and predicting the consequences of a changing environment and stressors such as pollution on the life histories of marine organisms. Here, we apply the simple and ... -
Multigenerational exposure to ocean acidification during food limitation reveals consequences for copepod scope for growth and vital rates
Pedersen, Sindre Andre; Håkedal, Ole Jakob; Salaverria-Zabalegui, Iurgi Imanol; Tagliati, Alice; Gustavson, Liv Marie; Jenssen, Bjørn Munro; Olsen, Anders Johny; Altin, Dag (Journal article; Peer reviewed, 2014)The copepod Calanus finmarchicus is a key component of northern Atlantic food webs, linking energy-transfer from phytoplankton to higher trophic levels. We examined the effect of different ocean acidification (OA) scenarios ... -
Produced water components: uptake kinetics and effects on the metabolism of the Arctic copepod Calanus glacialis
Bergentz, Sara Hanna Amalia (Master thesis, 2016)The oil exploration and search for new oil production fields is expanding further north and has reached the Arctic. Oil drilling activities release large amounts of produced water (PW) to the marine environment and sub-lethal ... -
The effects of textile microfibres on essential physiological processes in Calanus finmarchicus
Erichsen, Ingrid (Master thesis, 2021)Mikroplast (1–5000 µm) er et utbredt problem i det marine økosystemet som kan påvirke helsen til marine biota. Forskjellige marine arter spiser mikroplast, og dette har vist seg å kunne påvirke flere viktige fysiologiske ... -
The impact of TiO2 nanoparticles on uptake and toxicity of benzo(a)pyrene in the blue mussel (Mytilus edulis)
Farkas, Julia; Bergum, Signe; Nilsen, Emil Wear; Olsen, Anders Johny; Salaverria-Zabalegui, Iurgi Imanol; Ciesielski, Tomasz Maciej; Baczek, Tomasz; Konieczna, Lucyna; Salvenmoser, Willi; Jenssen, Bjørn Munro (Journal article; Peer reviewed, 2015)Nanoparticles are emerging contaminants of concern. Knowledge on their environmental impacts is scarce, especially on their interactive effects with other contaminants. In this study we investigated effects of titanium ... -
Uptake and effects of microplastic particles in selected marine microalgae species; Oxyrrhis marina and Rhodomonas baltica
Lyakurwa, Dionis Joachim (Master thesis, 2017)It is estimated that large numbers of microplastics are present in the marine environment and their concentrations are expected to rise in a foreseeable future. Interactions, uptake, and excretion rates as well as effects ... -
Uptake and excretion of polystyrene microplastics in the marine copepod Calanus finmarchicus
Halland, Gunhild Rogne (Master thesis, 2017)Studier av opptak og utskillelse av polystyren mikroplast i den marine kopepoden Calanus finmarchicus
