Formålet med denne oppgaven var å få en forståelse for hvilke påvirkninger to grupper studenter ved Universitetet i Tromsø opplever på sitt matvalg omkring sushi på restaurant. De to gruppene var studenter som spiser sushi og studenter som ikke spiser sushi. I tillegg til dette ville jeg i oppgaven forsøke å besvare følgende spørsmål: 1.Hvilke holdninger og preferanser har studenter ved Universitetet ...

Bioaktive forbindelser påvist hos marine invertebrater ses ofte å ha strukturelle likheter med bakterielle sekundærmetabolitter og antas derfor å være produsert av mikrobielle symbionter. Målet med oppgaven var å screene småskala kulturfiltrater fra marine bakterieisolater fra svamper og sjøpungen Synoicum pulmonaria for å identifisere mulige produsenter av sekundærmetabolitter ved sammenligning ...

In a paper in this journal entitled “Fear and loathing of the deep sea: why don’t people care about the deep sea?”, Jamieson et al. (2020) pose this question and answer it with many interesting perspectives from psychology, ocean literacy and philosophy. However, there is an inherent assumption in the question they ask that people do not care about the deep sea. In order to assess this assumption, ...

Nicotinic acetylcholine receptors (nAChRs) play an important role in the functioning of the central and peripheral nervous systems, and other organs of living creatures. There are several subtypes of nAChRs, and almost all of them are considered as pharmacological targets in different pathological states. The crude venom of the sea anemone Metridium senile showed the ability to interact with ...

Lake Victoria in East Africa provides fishery resources to fishing communities and governments. The dynamics of these fish resources are variable, complex and poorly understood. The perspectives of different scientists, users and stakeholders are in disagreements on the state of Lake Victoria’s ecosystem and fisheries, thus creating a problem to constructive discussion regarding the fisheries future. ...

The introduction of the Nordmøre grid to shrimp trawls has reduced the issue of bycatch to that of small-sized species and juveniles that are able to pass through the grid and enter the small-meshed cod end together with the targeted shrimp. This study estimated the size- and species-selective performance of the Nordmøre grid in the configuration most often applied by fishermen and made a preliminary ...

Hovedmålet med prosjektet er å dokumentere effekten av Permaskjørt i forhold til å redusere luspåslag, i tillegg til å dokumentere hvordan innretningen påvirker miljøet i merden, fiskens biologiske forhold og merdens hovedkomponenter i forhold til en merd uten Permaskj¢rt. <br> I prosjektet har det blitt gjennomført ulike forskningsaktiviteter, som modellforsøk, fullskalaforsøk, numeriske ...

Offshore drilling operations result in the generation of drill cuttings and localized smothering of the benthic habitats. This study explores bacterial community changes in the in the upper layers of the seafloor resulting from an exploratory drilling operation at 1400 m water depth on the Barents Sea continental slope. Significant restructurings of the sediment microbiota were restricted to the ...

Microalgae are grown in different habitats and conditions, such as high salinity, extreme temperatures, and variable pH. Cold-adapted microalgae may have the capacity of generating high biomass production, which can potentially be produced under cold and light-limited conditions in the Arctic. Most microalgae are obligated photoautotrophs; however, few species have been found living in complete ...

Rapid warming in the Arctic is drastically impacting marine ecosystems, affecting species communities and food-web structure. Pelagic Themisto amphipods are a major component of the Arctic zooplankton community and represent a key link between secondary producers and marine vertebrates at higher trophic levels. Two co-existing species dominate in the region: the larger Themisto libellula, considered ...
