Desnity dependent habitat use of Atlantic salmon, Salmo salar L.- stranding in hydropower rivers
(Master thesis, 2011)An experiment was performed in four artificial stream channels during summer and autumn to investigate the effects of biotic and abiotic factors on habitat choice of juvenile Atlantic salmon (Salmo salar). To investigate ... -
Detecting climate signals in populations across life histories
(Peer reviewed; Journal article, 2021)Climate impacts are not always easily discerned in wild populations as detecting climate change signals in populations is challenged by stochastic noise associated with natural climate variability, variability in biotic ... -
Detection and differentiation of breast cancer sub-types using a cPLA2a activatable fluorophore
(Journal article; Peer reviewed, 2019)Cytosolic phospholipase A2α (cPLA2α) has been shown to be elevated in breast cancer and is a potential biomarker in the differentiation of molecular sub-types. Using a cPLA2α activatable fluorophore, DDAO arachidonate, we ... -
Detection of Pso p27 in Prostate Cancer
(Master thesis, 2012)AbstractThe mechanisms causing psoriasis and other autoimmune diseases are not known with certainty, although it has been indicated that the factors behind them are similar. These similarities are, among others, heredity ... -
Detection of trace elements in Svalbard reindeer (Rangifer tarandus platyrhynchus) faeces in Longyearbyen, Adventdalen and Kapp Linné
(Master thesis, 2018)The Arctic is considered a deposition and accumulation region for several possible toxic pollutions, including toxic non-essential elements, that can enter the Arctic environment via long-range transport from other ... -
Deteksjon og kvantifisering av lipofile algetoksiner i skjell ved LC-MS/LC-MSMS
(Master thesis, 2013)Mikroskopiske plantealger kan danne marine algetoksiner i svært lave konsentrasjoner, og disse algetoksinene kan under gitte forhold akkumulere i skjell. I næringsmiddelsammenheng kan inntak av giftige skjell føre til ... -
Determinants of age at first reproduction and lifetime breeding success revealed by full paternity assignment in a male ungulate
(Journal article; Peer reviewed, 2018)Age at first reproduction is an important determinant of individual variation in reproductive success in ungulates, but few studies have examined its relationship with later fitness‐related traits in males. We used a ... -
Determinants of Conservation Support in Local Communities: A Case Study of Indawgyi Wildlife Sanctuary, Myanmar
(Master thesis, 2020)Local communities living adjacent to Protected Areas (PA) play a vital role in biodiversity conservation. Depending on their positive and negative associations with the PA, they can either be conservation allies or ... -
Determinants of tree seedling establishment in alpine tundra
(Peer reviewed; Journal article, 2020)Questions Changes in climate and herbivory pressure affect northern alpine ecosystems through woody plant encroachment, altering their composition, structure and functioning. The encroachment often occurs at unequal rates ... -
Determination of steroid hormones in grey seal (Halichoerus grypus) blood plasma using convergence chromatography tandem mass spectrometry
(Peer reviewed; Journal article, 2023)A hybrid solid phase extraction (HybridSPE) protocol tailored to ultra-performance convergence chromatography tandem mass spectrometry (UPC2-MS/MS) was developed for the determination of 19 steroid hormones in grey seal ... -
Developing a laboratory cultivation protocol for local species of Porphyra spp.
(Master thesis, 2016)The cultivation of Porphyra for use in food has a long tradition in Asian countries, and with recent food trends and nutritional awareness, macroalgae has become a popular ingredient throughout the rest of the world as ... -
Developing common protocols to measure tundra herbivory across spatial scales
(Peer reviewed; Journal article, 2021)Understanding and predicting large-scale ecological responses to global environmental change requires comparative studies across geographic scales with coordinated efforts and standardized methodologies. We designed, ... -
Development and application of a health-based framework for informing regulatory action in relation to exposure of microplastic particles in California drinking water
(Peer reviewed; Journal article, 2022)Microplastics have been documented in drinking water, but their effects on human health from ingestion, or the concentrations at which those effects begin to manifest, are not established. Here, we report on the outcome ... -
Development and behavior of Plaintive Cuckoo (Cacomantis merulinus) nestlings and their Common Tailorbird (Orthotomus sutorius) hosts
(Journal article; Peer reviewed, 2019)Background Our knowledge of avian brood parasitism is primarily based on studies of a few selected species. Recently, researchers have targeted a wider range of host–parasite systems, which has allowed further evaluation ... -
Development and calibration of a high dynamic range and autonomous ocean-light instrument to measure sub-surface profiles in ice-covered waters
(Journal article; Peer reviewed, 2023)The optical chain and logger (OptiCAL) is an autonomous ice-tethered observatory equipped with multiple light sensors for mapping the variation of light with depth. We describe the instrument and present an ensemble ... -
