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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
Comparative analysis of acoel embryonic development
(Doctoral thesis, 2020-10-02)Acoels are bilaterally symmetric aquatic worms, that lack a through gut and have a single body opening to their digestive syncytium. Although they were initially placed within spiralians, because of their morphological ... -
Micronekton biomass distribution, improved estimates across four north Atlantic basins
(Peer reviewed; Journal article, 2019)Distribution of micronekton was investigated during early summer of 2013, using data from a cruise covering the central parts of four north Atlantic basins, the Norwegian Sea (NS), Iceland Sea (ICS), Irminger Sea (IRS), ... -
Contaminant accumulation and biological responses in Atlantic cod (Gadus morhua) caged at a capped waste disposal site in Kollevåg, Western Norway
(Peer reviewed; Journal article, 2019)The aim of this study was to assess whether fish in Kollevåg, a sheltered bay on the western coast of Norway, previously utilized as a waste disposal site, could be affected by environmental contaminants leaking from the ... -
Associated bacteria of Botryococcus braunii (Chlorophyta)
(Peer reviewed; Journal article, 2019-03-27)Botryococcus braunii (Chlorophyta) is a green microalga known for producing hydrocarbons and exopolysaccharides (EPS). Improving the biomass productivity of B. braunii and hence, the productivity of the hydrocarbons and ... -
Anticancer activity in Planctomycetes
(Peer reviewed; Journal article, 2019-01-07)There is a strong need to develop new drugs against many severe diseases. Therapy resistance is a major problem, for instance, in infectious diseases and cancer. Drug discovery has again turned to nature to search for ... -
Intramuscular vaccination of Atlantic lumpfish (Cyclopterus lumpus L.) induces inflammatory reactions and local immunoglobulin M production at the vaccine administration site
(Peer reviewed; Journal article, 2019)Atlantic lumpfish were vaccinated by intramuscular (im) or intraperitoneal (ip) injection with a multivalent oil‐based vaccine, while control fish were injected with phosphate‐buffered saline. Four lumpfish per group were ... -
Is habituation measurable in lumpfish cyclopterus lumpus when used as cleaner fish in Atlantic salmon Salmo salar aquaculture?
(Peer reviewed; Journal article, 2019)To investigate how lumpfish interact in Atlantic salmon aquaculture, physiological stress responses and changes in behaviour were analysed in experienced and naive lumpfish. Experienced lumpfish (30.2 ± 7.93 g, mean ± SD) ... -
Light comfort zone in a mesopelagic fish emerges from adaptive behaviour along a latitudinal gradient
(Peer reviewed; Journal article, 2019)Throughout the oceans, small fish and other micronekton migrate between daytime depths of several hundred meters and near-surface waters at night. These diel vertical migrations of mesopelagic organisms structure pelagic ... -
Lipid production in nannochloropsis gaditana during nitrogen starvation
(Peer reviewed; Journal article, 2019)The microalga Nannochloropsis gaditana is a natural producer of triacylglycerol (TAG) and the omega-3 fatty acid eicosapentaenoic acid (EPA). TAG accumulation is induced by nitrogen starvation. The biomass-specific photon ... -
Inferring Atlantic salmon post-smolt migration patterns using genetic assignment
(Peer reviewed; Journal article, 2019)Understanding migratory patterns is important for predicting and mitigating unwanted consequences of environmental change or anthropogenic challenges on vulnerable species. Wild Atlantic salmon undergo challenging migrations ...
