A genomic delimitation of European Sphagnum subgenus Subsecunda with particular emphasis on the taxonomically difficult allodiploids Sphagnum auriculatum Schimp. and Sphagnum inundatum Russow
(Master thesis, 2021)Allopolyploidi er en viktig faktor for artsdannelse i planter. Det er et utbredt fenomen blant moser og bidrar til den taksonomiske forvirringen i mange underslekter i den morfologisk og økologisk mangfoldige moseslekten ... -
A global compilation of coccolithophore calcification rates
(Journal article; Peer reviewed, 2018)The biological production of calcium carbonate (CaCO3), a process termed calcification, is a key term in the marine carbon cycle. A major planktonic group responsible for such pelagic CaCO3 production (CP) is the ... -
A high density linkage map enables a second generation collared flycatcher genome assembly and reveals the pattern of avian recombination rate variation and chromosomal evolution.
(Journal article; Peer reviewed, 2014-06-17)Detailed linkage and recombination rate maps are necessary to use the full potential of genome sequencing and population genomic analyses. We used a custom collared flycatcher 50 K SNP array to develop a high-density linkage ... -
A high local species richness and biodiversity within high-latitude calcareous aggregates of tube-building polychaetes
(Journal article; Peer reviewed, 2011) -
A Histological Analysis of the Arm and Sucker Cup Nervous System in the Curled Octopus (Eledone cirrhosa)
(Master thesis, 2024)Spesialiserte sansesystemer og anatomiske strukturer allokert til å prosessere informasjonen de samler er kritiske for dyrs overlevelse og reproduksjon. Den åttearmede blekkspruten er en sansespesialist, som benytter sine ... -
A Hybrid Flow Cytometric Approach to the Mussel Micronucleus Cytome Assay
(Master thesis, 2023)Til tross for den utbredte bruken av musling mikronukleus cytom-assayet innen akvatisk økotoksikologi(Bolognesi and Fenech, 2012), så har denne protokollen flere begrensninger og utfordringer ved seg; hvorav de fleste kan ... -
A miniature world in decline: European Red List of Mosses, Liverworts and Hornworts
(Book, 2019)This publication has been prepared by IUCN (International Union for Conservation of Nature) as a deliverable of the LIFE European Red Lists project (LIFE14 PRE BE 001). A miniature world in decline: The European Red List ... -
A mixture model approach to sample size estimation in two- sample comparative microarray experiments
(Journal article; Peer reviewed, 2008)Background: Choosing the appropriate sample size is an important step in the design of a microarray experiment, and recently methods have been proposed that estimate sample sizes for control of the False Discovery Rate ... -
A molecular and morphological study of Bivalvia (Phylum: Mollusca) in Norwegian waters, with emphasis on Pectinidae Rafinesque, 1815
(Master thesis, 2019)Art regnes for å være den grunnleggende enheten innenfor biologi. Dette understreker viktigheten av både avgrensning av arter, å finne antall arter og grensen mellom disse, og taksonomi, å navngi, beskrive og klassifisere ... -
A multi-marker metabarcoding approach to study tardigrade diversity in forest ecosystems.
(Master thesis, 2019)Som annen mikroskopisk fauna blir bjørnedyr ofte oversett i økologiske undersøkelser. Med sin kosmopolitiske utbredelse i alt fra sedimenter på havets dyp til høyalpine fjellområder, spiller bjørnedyr viktige roller i mange ... -
A new NDVI measure that overcomes data sparsity in cloud-covered regions predicts annual variation in ground-based estimates of high arctic plant productivity
(Journal article; Peer reviewed, 2018)Efforts to estimate plant productivity using satellite data can be frustrated by the presence of cloud cover. We developed a new method to overcome this problem, focussing on the high-arctic archipelago of Svalbard where ... -
A new Norwegian bioeconomy based on cultivation and processing of seaweeds: Opportunities and R&D needs
(Research report, 2014) -
A novel compound isolated from Sclerochloa dura has anti-inflammatory effects
(Journal article; Peer reviewed, 2016)The activation of phospholipase A2 (PLA2) by means of pro-inflammatory cytokines results in the subsequent release of arachidonic acid (AA) and generates eicosanoids, which further propagate inflammation. Through cyclooxygenases ... -
A physiological understanding of organismal responses to fire
(Journal article; Peer reviewed, 2019)Devastation of both natural and human habitats due to wildfires is becoming an increasingly prevalent global issue. Fire-adapted and fire-prone regions, such as California and parts of Australia, are experiencing more ... -
A pilot study assessing drones for mapping and monitoring of European shags
(Master thesis, 2019)Sjøfuglpopulasjoner er sensitive til forandringer i sitt miljø. De kan derfor studeres som indikatorer for endringer i økosystemer. I mellomtiden har droneteknologier økt i viktighet som verktøy i økologistudier og de har ... -
A review of ecological impacts of global climate change on persistent organic pollutant and mercury pathways and exposures in arctic marine ecosystems
(Journal article; Peer reviewed, 2015)Bioaccumulative and biomagnifying contaminants, such as persistent organic pollutants (POPs) and mercury (Hg), have for decades been recognized as a health concern in arctic marine biota. In recent years, global climate ... -
A Review of Fennoscandian Stictochironomus (Diptera: Chironomidae), with the description of a species new to science
(Master thesis, 2023)Chironomidae, eller fjærmygg på norsk, er en av de mest artsrike og utbredte familiene av ferskvannsinsekter i verden. Under slekten Stictochironomus Kieffer, 1919 finnes det seks beskrevne arter i Fennoskandia, men DNA ... -
A sex-inducing pheromone triggers cell cycle arrest and mate attraction in the diatom Seminavis robusta
(Journal article; Peer reviewed, 2016)Although sexual reproduction is believed to play a major role in the high diversification rates and species richness of diatoms, a mechanistic understanding of diatom life cycle control is virtually lacking. Diatom sexual ... -
A shift in the thermoregulatory curve as a result of selection for high activity-related aerobic metabolism
(Journal article; Peer reviewed, 2017)According to the “aerobic capacity model,” endothermy in birds and mammals evolved as a result of natural selection favoring increased persistent locomotor activity, fuelled by aerobic metabolism. However, this also increased ... -
A spatio-temporally explicit random encounter model for large-scale population surveys
(Journal article; Peer reviewed, 2016)Random encounter models can be used to estimate population abundance from indirect data collected by non-invasive sampling methods, such as track counts or camera-trap data. The classical Formozov–Malyshev–Pereleshin (FMP) ...
