The taxonomy and molecular phylogeny of Potentilla L. (Rosaceae) : An investigation of generic delimitation and reticulate evolution, using low-copy nuclear markers
(Doctoral thesis, 2021-01-15)The process of polyploidization (genome duplication) is a common mechanism in plant speciation. Autopolyploidy arises within one species, and allopolyploidy arises after hybridization. Ploidy levels in the genus Potentilla ... -
Microplastic in the Urban Environment - Concentrations and Sources in Streets and Sand Traps
(Master thesis, 2021-01-19) -
Palm fruit colours are linked to the broad-scale distribution and diversification of primate colour vision systems
(Journal article; Peer reviewed, 2020)A long-standing hypothesis in ecology and evolution is that trichromatic colour vision (the ability to distinguish red from green) in frugivorous primates has evolved as an adaptation to detect conspicuous (reddish) fruits. ... -
Interactions between marine nutrients and 2, 3, 7, 8 – Tetrachlorodibenzo-p-dioxin toxicity on reproduction of male wistar han rats
(Master thesis, 2020-12-23)Dioxins and dioxin-like polychlorinated biphenyls (dl-PCBs) are chemical congeners formed as by-products from incomplete thermic reactions, found in the environment because of improper disposal from industrial processes ... -
Early studies on a novel phosphoinositide 3-kinase p110β isoform, and its localisation
(Master thesis, 2020-12-23)Phosphoionositide 3-kinase (PI3K) is a family of enzymes that are part of the PI3K signalling pathway, which is one of the most often altered pathways in human cancer. The PI3K family is divided into three classes, where ... -
Refilling behaviour of Atlantic salmon (Salmo salar) in submerged sea cages with air-dome
(Master thesis, 2020-12-19)Production of Atlantic salmon in submerged sea cages may solve surface related challenges like sea lice and toxic algae blooms but previous trials have faced problems linked to buoyancy. Korsøen et al. (2012) showed that ... -
The developmental basis for the evolution of new morphologies in Spiralia
(Doctoral thesis, 2020-11-20)Spiralia is a clade of bilaterally symmetrical animals, which display an extreme diversity of divergent body plans accompanied by the presence of multiple subclades- specific morphological and developmental characters. ... -
The role of acetylation of histone H3 lysine 27 in enhancer function
(Doctoral thesis, 2020-12-09)The histone modification H3K27ac is a hallmark of active enhancers. However, its role in enhance-specific activity remains obscure. We applied mass spectrometry-based quantitative interaction proteomics to determine proteins ... -
Lithistid demosponges of the North Atlantic : Taxonomy, Diversity and Biogeographic Patterns
(Doctoral thesis, 2020-11-27)Sponges, phylum Porifera Grant, 1836, comprise a group of benthic filter-feeding organisms, which are one of the oldest living groups of metazoans on Earth. Currently, four classes are recognized within the Phylum, of which ... -
Sår og sårheling hos atlantisk laks (Salmo salar L.) i RAS med sjøvannstilsetning og i tradisjonelle sjømerder
(Master thesis, 2020-12-12)Produksjon av postsmolt atlantisk laks (Salmo salar) i resirkulerende akvakultursystemer (RAS) med sjøvannstilsetning er tatt i bruk for å forkorte produksjonstiden i sjø. Dette er som følge av store utfordringer knyttet ... -
Bacteriophages targeting pathogenic bacteria isolated from lumpfish (Cyclopterus lumpus L.) and Atlantic salmon (Salmo salar L.)
(Master thesis, 2020-12-03)Bacterial diseases in aquaculture lead to reduced health and mortality of fish as well as economic consequences for the producer. Antibiotics are an important antimicrobial to control bacterial diseases, however, concerns ... -
Does Brownification and Iron Affect Microbial Communities and Mixotrophic Activities? Experiences From a Mesocosm Experiment
(Master thesis, 2020-11-13)In one millilitre of seawater there is on average approximately a million microbial cells, and these are largely responsible for nearly half of all primary production on Earth. Mixotrophic microorganisms are ubiquitous in ... -
Er BIO 101 studentene anvendelsesorienterte? En kvantitativ studie om biologistudentenes læringsstrategier basert på Vermunts læringsmønster
(Master thesis, 2020-11-11)Bakgrunn: Denne biologididaktiske mastergraden tar for seg Vermunts lærings- mønstre (ILS ), som er bygget på SAL og SRL tradisjonen. Basert på dette fant Vermunt (1996) fire læringsstrategier (læringsorienteringer) som ... -
Viral-host interactions: from strain to natural planktonic communities
(Doctoral thesis, 2017-10-13)Being the most abundant and diverse entities in planet Earth, viruses are thought to play a relevant role in controlling the composition and diversity in phytoplanktonic microbial communities. Microbial communities sustain ... -
Systematic revision of the genus Jorunna (Nudibranchia: Discodorididae) in Europe with a focus on the J. tomentosa species complex
(Master thesis, 2020-09-01)Jorunna is a genus of Nudibranchia in the family Discodorididae, currently comprising 21 recognized valid species with a worldwide coastal distribution in the four main biogeographical regions Eastern and Western Atlantic, ... -
Conformational selection mechanism of ASHH2 methyltransferase CW domain recognising H3K4me1 histone modification
(Doctoral thesis, 2020-10-26)From simple double-stranded molecule DNA is packed in the nucleus via different intermediate structures with help of various proteins organizing a complex structure referred to as chromatin. A subunit of chromatin is a ... -
Biological and ecological effects of Ligula intestinalis (Linnaeus, 1758) in a fish host Engraulicypris sardella (Gütter, 1868) from Tanzanian side of Lake Nyasa
(Doctoral thesis, 2020-10-23)The current thesis investigates the epidemiological, behavioral and evolutionary effects of the tapeworm Ligula intestinalis in the ‘Nyasa sardine’ (Engraulicypris sardella), an intermediate fish host, endemic to Lake ...
