Climate trends, weather fluctuations and calving phenology in Svalbard reindeer (Rangifer tarandus platyrhynchus)
(Master thesis, 2016)Reproduction is known to be one of the most energetically demanding processes in the life of an organism, and in seasonal environments, vertebrate offspring production is therefore timed to coincide with the annual peak ... -
Community structure and biodiversity of the benthic megafauna at the inactive hydrothermal site Mohn's Treasure, on the Mohn's Ridge, Arctic Mid-Ocean Ridge (AMOR)
(Master thesis, 2017)This thesis aims to describe the deep sea benthic megafauna communities of the geologically inactive vent site of Mohn's Treasure, situated on the Mohn's Ridge, a part of the Arctic Mid-Ocean Ridge (AMOR). The data was ... -
Cultivation of Haematococcus lacustris for Production of Astaxanthin and Chl a. - Utilization of Processed Water from Paper Industry for Microalgae Cultivation.
(Master thesis, 2018)Microalgae such as Haematococcus lacustris are rich sources for pigments such as astaxanthin and chlorophyll, and are attractive organisms of both commercial and scientific interest. Processed water from several industries ... -
Ex vivo analyse av interleukin-6 fra humant helblod og forslag til optimalisering av metoden
(Master thesis, 2017)Cytokiner er små signalmolekyler som er viktige i kommunikasjonen mellom celler og i reguleringen av immunresponser [1]. Produksjonen av cytokiner er nøye kontrollert, og det er mange signalkaskader som ender med syntetisering ... -
Eyes beneath the surface - using a miniROV to reveal the habitat and dietary choices of the European shag
(Master thesis, 2018)The population of sea birds in Norway is drastically declining, and numbers of breeding European shag (Phalacrocorax aristotelis) in the nesting colony in Runde, Norway, has declined with ~96% in the last 40 years. Mapping ... -
From gene lists to interaction networks for biological interpretation - Reinterpretation of the results from a diet intervention study in light of a new statistical analysis
(Master thesis, 2017)The results of a diet intervention study aiming to enlighten dietary carbohydrates role in proinflammatory responses have been reviewed in light of a new statistical analyses conducted on the microarray data. Two diets, a ... -
Growth of the Polychaete Hediste diversicolor (O. F. Müller, 1776) fed on Smolt Sludge and Biogas Residues - Evaluation of RNA/DNA Ratio as growth indicator
(Master thesis, 2018)The last decades have seen decimation of several fish stocks, leading to increased governmental restrictions on the worlds wild fish catch. In contrast, the consumption demand of marine food has increased greatly. To meet ... -
Life-history Effects of Metal contamination in Arctic snow buntings (Plectrophenax nivalis) breeding in Adventdalen, Svalbard.
(Master thesis, 2016)The present study was the first to investigate element concentrations in feathers of both nestling and adult snow buntings in the Arctic environment of Adventdalen. Significant differences in concentrations between nestling- ... -
Molecular quantification of sea lice in and around sea cages - A study comparing the molecular quantification method qPCR against a conventional method
(Master thesis, 2017)The aquaculture production of atlantic salmon (Salmo salar) have been growing in a steady pace, but for further expansion of the industry it is necessary to solve environmental challanges, including those related to sea ... -
Phylogenetic Diversity of Arctic Vertebrate Herbivores
(Master thesis, 2017)Understanding spatial diversity patterns, and factors shaping these patterns, is crucial for conservation planning, and is particularly important in areas undergoing severe climatic change. Traditionally, spatial diversity ... -
Physical activity tracking - Personal activity intelligence (PAI) versus 10000 steps per day and the effects on cardiorespiratory fitness, body composition and blood pressure in inactive overweight and obese
(Master thesis, 2018)Increased amounts of sedentary time, and less physical activity (PA) have become a global concern, and may result in increased risk of cardiovascular disease (CVD). Thus, it has become an important task to increase PA in ... -
Possible Anthropogenic Sources of Toxic Elements in Snow Bunting Nestlings (Plectrophenax nivalis) in Adventdalen, Svalbard.
(Master thesis, 2017)The Arctic environment is exposed to natural and anthropogenic contamination as a result of local, regional and global pollution. Contaminants accumulating in the Arctic may influence both biotic and abiotic factors. ... -
Saccharina latissima, effekt av utskiftningsintervall av medium for vegetative gametofytter og utsåingstetthet på vekst, samt stresstester av kimplanter.
(Master thesis, 2016)Norge er et land som har et stort potensiale for å drive tareoppdrett med sin langstrakte kystlinje. For at denne næringen skal bli konkurransedyktig, må næringen gjøres kostnadseffektiv. For økt produksjon av kimplanter ... -
Spatiotemporal Variation and Fitness Consequences of Blood Hemoglobin Concentration in free-living House Sparrow (Passer domesticus) Nestlings
(Master thesis, 2018)Studies have suggested that variation in hemoglobin concentration among individuals can be used as an indicator of individual condition as it reflects the amount of oxygen that is supplied to the tissues. Thus, it is ...
