Winters are changing: snow effects on Arctic and alpine tundra ecosystems
(Journal article; Peer reviewed, 2022)Snow is an important driver of ecosystem processes in cold biomes. Snow accumulation determines ground temperature, light conditions and moisture availability during winter. It also affects the growing season’s start and ... -
Engaging students in SDG 14 by placing them at the centre of their own learning: SDG214 at the University of Bergen as an example
(Chapter, 2021)Educating students on the sustainable development goals (SDGs) calls for teaching where students are at the centre of their own learning. Sustainability questions are ‘wicked problems’, where no single, correct answer ... -
Vegetation- memory effects and their association with vegetation resilience in global drylands
(Journal article, 2022)Vegetation memory describes the effect of antecedent environmental and ecological conditions on the present ecosystem state and has been proposed as an important proxy for vegetation resilience. In particular, strong ... -
Fishes in a changing world: learning from the past to promote sustainability of fish populations
(Journal article; Peer reviewed, 2018)Populations of fishes provide valuable services for billions of people, but face diverse and interacting threats that jeopardize their sustainability. Human population growth and intensifying resource use for food, water, ... -
Accumulation and distribution of microplastics in coastal sediments from the inner Oslofjord, Norway
(Journal article; Peer reviewed, 2021)Microplastic presence in benthic marine systems is a widely discussed topic. The influence of the natural matrix on microplastic distribution within the sedimentary matrix is often overlooked. Marine sediments from the ... -
Sex differences in the early life stages of the salmon louse Lepeophtheirus salmonis (Copepoda: Caligidae)
(Journal article; Peer reviewed, 2022)Salmon lice are ectoparasites on salmonids and feed on blood, mucus, and skin from their hosts. This causes high annual costs for treatment and control for the aquaculture industry. Salmon lice have a life cycle consisting ... -
A paleoecological context to assess the development of oak forest in Colombia: A comment on Zorilla-Azcué, S., Gonzalez-Rodríguez, A., Oyama, K., González, M.A., & Rodríguez-Correa, H., The DNA history of a lonely oak: Quercus humboldtii phylogeography in the Colombian Andes. Ecology and Evolution 2021, doi: 10.100-2/ ece3.7529
(Journal article; Peer reviewed, 2022)The present “comment” on Zorilla-Azcué et al.’s paper “The DNA history of a lonely oak: Quercus humboldtii phylogeography in the Colombian Andes. Ecology and Evolution 2021, doi:10.100-2/ece3.7529” provides the paleoecological ... -
Anoxybacillus karvacharensis sp. nov., a novel thermophilic bacterium isolated from the Karvachar geothermal spring in Nagorno-Karabakh
(Journal article; Peer reviewed, 2021)Twelve thermophilic Anoxybacillus strains were isolated from sediment and water samples from a Karvachar hot spring located in the northern part of Nagorno-Karabakh. Based on phenotypic, chemotaxonomic and phylogenetic ... -
Daily rhythms of intestinal cholecystokinin and pancreatic proteases activity in Senegalese sole juveniles with diurnal and nocturnal feeding
(Journal article; Peer reviewed, 2021)The influence of diurnal and nocturnal feeding on daily rhythms of gut levels of cholecystokinin (CCK) and the activity of two key pancreatic proteases, trypsin and chymotrypsin, were examined in juveniles of Senegalese ... -
Linking dispersal connectivity to population structure and management boundaries for saithe in the Northeast Atlantic
(Journal article; Peer reviewed, 2021)Population connectivity is an increasingly important focal area for the understanding of how marine fish populations respond to anthropogenic pressures like climate change and fisheries. Our model species, the saithe ... -
Nutrient fuxes from an Arctic seabird colony to the adjacent coastal marine ecosystem
(Journal article; Peer reviewed, 2022)Seabirds are important vectors for nutrient transfer across ecosystem boundaries. In this seasonal study, we evaluate the impact of an Arctic colony (Alkhornet, Svalbard) of Black-legged Kittiwakes (Rissa tridactyla) and ... -
Anthropogenically impacted lake catchments in Denmark reveal low microplastic pollution
(Journal article; Peer reviewed, 2022)Microplastics have been detected in lake environments globally, including in remote regions. Agricultural and populated areas are known to congregate several inputs and release pathways for microplastic. This study ... -
Higher mortality of the less suitable brown trout host compared to the principal Atlantic salmon host when infested with freshwater pearl mussel (Margaritifera margaritifera) glochidia
(Journal article; Peer reviewed, 2021)The freshwater pearl mussel (Margaritifera margaritifera) is a highly host-specific parasite, with an obligate parasitic stage on salmonid fish. Atlantic salmon (Salmo salar) and brown trout (Salmo trutta f. trutta and ... -
Endozoicomonadaceae symbiont in gills of Acesta clam encodes genes for essential nutrients and polysaccharide degradation
(Journal article; Peer reviewed, 2021)Gammaproteobacteria from the family Endozoicomonadaceae have emerged as widespread associates of dense marine animal communities. Their abundance in coral reefs involves symbiotic relationships and possibly host nutrition. ... -
Neural activation in photosensitive brain regions of Atlantic salmon (Salmo salar) after light stimulation
(Journal article; Peer reviewed, 2021)Photoreceptive inputs to the teleost brain are perceived as image of the visual world and as photo-modulation of neuroendocrine and neuronal signals. The retina and pineal organ are major receptive organs with projections ... -
An automated approach for fringe frequency estimation and removal in infrared spectroscopy and hyperspectral imaging of biological samples
(Journal article; Peer reviewed, 2021)In infrared spectroscopy of thin film samples, interference introduces distortions in spectra, commonly referred to as fringes. Fringes may alter absorbance peak ratios, which hampers the spectral analysis. We have previously ... -
Ontogenetic niche shifts in a locally endangered tree species (Olea europaea subsp. cuspidata) in a disturbed forest in Northern Ethiopia: Implications for conservation
(Journal article; Peer reviewed, 2021)Understanding the responses of different ontogenetic stages to environmental and human disturbance factors is essential for developing efficient conservation strategies for endangered plant species. We examined how three ... -
Thermococcus bergensis sp. nov., a Novel Hyperthermophilic Starch-Degrading Archaeon
(Journal article; Peer reviewed, 2021)A novel hyperthermophilic archaeon, termed strain T7324T, was isolated from a mixed sulfate-reducing consortium recovered from hot water produced from a deep North Sea oil reservoir. The isolate is a strict anaerobic ... -
Vital rates in early life history underlie shifts in biotic interactions along bioclimatic gradients: An experimental test of the Stress Gradient Hypothesis
(Journal article; Peer reviewed, 2021)Question The Stress Gradient Hypothesis (SGH) predicts that competition and facilitation shift along stress gradients. We ask if the underlying mechanisms operate at specific points in plant life history, and if patterns ... -
