Pattern and process in Norwegian upland grasslands: a functional analysis
(Peer reviewed; Journal article, 2002)Four classes of functional and morphological plant traits (FMT) – established strategies (the CSR scheme sensu Grime 1979), life-forms (sensu Raunkiaer 1934), morphology, and regenerative strategies – are used as tools for ... -
Pattern and process in Norwegian upland grasslands: an integrated ecological approach.
(Doctoral thesis, 2002-06-04)In this thesis I examine community patterns and the effects of disturbances on these patterns within successional subalpine grasslands at summer farms in Norway. On a broad scale, I investigate how environment, land-use ... -
Patterns of psychiatric comorbidity and genetic correlations provide new insights into differences between attention-deficit/hyperactivity disorder and autism spectrum disorder
(Peer reviewed; Journal article, 2019-04-28)Background Attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) share common genetic factors but seem to have specific patterns of psychiatric comorbidities. There are few systematic studies ... -
Påvirker tidspunktet for beriking av oppvekstmiljøet romlig læring hos unglaks (Salmo salar)?
(Master thesis, 2016-06-01)Å forflytte seg mellom biologisk viktige områder er en viktig del av hverdagen til en rekke dyr. Dette krever evnen til å sanse, prosessere og memorere informasjon fra omverdenen, som er fylt med enorme mengder potensielle ... -
PCB-126 spiked to polyethylene microplastic ingested by juvenile Atlantic cod (Gadus morhua) accumulates in liver and muscle tissues
(Journal article; Peer reviewed, 2023)In the present study, polyethylene (PE) microplastics (150–300 μm) were added to Atlantic cod (Gadus morhua) feeds at 1 %, either in their present form (Virgin PE) or spiked with PCB-126 (Spiked PE). The feeds were given ... -
A pedigree-based experiment reveals variation in salinity and thermal tolerance in the salmon louse, Lepeophtheirus salmonis
(Peer reviewed; Journal article, 2017-12)The salmon louse is a highly abundant ectoparasitic copepod of salmonids in the North Pacific and Atlantic. Widespread and rapid development of resistance to chemical agents used to delouse salmonids on marine farms is now ... -
Pelagic organisms avoid white, blue, and red artificial light from scientific instruments
(Journal article; Peer reviewed, 2021)In situ observations of pelagic fish and zooplankton with optical instruments usually rely on external light sources. However, artificial light may attract or repulse marine organisms, which results in biased measurements. ... -
The peptide transporter 1a of the zebrafish Danio rerio, an emerging model in nutrigenomics and nutrition research: Molecular characterization, functional properties, and expression analysis
(Peer reviewed; Journal article, 2019-12-19)Background: Peptide transporter 1 (PepT1, alias Slc15a1) mediates the uptake of dietary di/tripeptides in all vertebrates. However, in teleost fish, more than one PepT1-type transporter might function, due to specific whole ... -
Peptide-Based Coacervate-Core Vesicles with Semipermeable Membranes
(Journal article; Peer reviewed, 2022)Coacervates droplets have long been considered as potential protocells to mimic living cells. However, these droplets lack a membrane and are prone to coalescence, limiting their ability to survive, interact, and organize ... -
Performance and welfare of Atlantic salmon, Salmo salar L. post-smolts in recirculating aquaculture systems: Importance of salinity and water velocity
(Journal article; Peer reviewed, 2020)Producing a larger post‐smolt in recirculating aquaculture systems (RAS) could shorten the production time in sea cages and potentially reduce mortality. Knowledge of the biological requirements of post‐smolts in ... -
Period lenght in cyclic animal populations
(Peer reviewed; Journal article, 2005)Although cyclic animal dynamics have long been a focus of scientific interest, the variable cycle lengths are poorly understood. Based on a review of the literature, we suggest that period length in animals showing multiannual ... -
Periodic changes in the zooplankton of the North Sea during the twentieth century linked to oceanic inflow
(Journal article, 2003)Oceanic inflow is estimated to contribute more than 90% of the nutrient input into the North Sea. Variability in the volume, chemical properties, biological content and source of the inflowing water is thus likely to have ... -
Periodicity of otolith check formation in the juvenile plaice Pleuronectes platessa
(Belle W.Baruch Library in Marine Science; 19, Chapter; Peer reviewed, 1995)Juvenile (Pleuronectes platessa L.) were sampled in the intertidal zone of Port Erin Bay (Isle of Man, Irish Sea) by push-net in the summers of 1990 and 1992. Check formation on the sagittal otoliths was examined to test ... -
Peripheral and central employment of acid-sensing ion channels during early bilaterian evolution
(Journal article; Peer reviewed, 2023)Nervous systems are endowed with rapid chemosensation and intercellular signaling by ligand-gated ion channels (LGICs). While a complex, bilaterally symmetrical nervous system is a major innovation of bilaterian animals, ... -
Peroxisome Proliferator-Activated Receptors (PPARs) As Tools For Studying Effects Of Contaminants On The Lipid Metabolism In Atlantic Cod (Gadus morhua)
(Master thesis, 2017-11-09)Due to its habitats near offshore oil platforms, petroleum recovery facilities, as well as coastal industries and municipal wastewater treatment plants, Atlantic cod (Gadus morhua) must cope with both legacy and emerging ... -
Persist in place or shift in space? Evaluating the adaptive capacity of species to climate change
(Journal article; Peer reviewed, 2020)Assessing the vulnerability of species to climate change serves as the basis for climate-adaptation planning and climate-smart conservation, and typically involves an evaluation of exposure, sensitivity, and adaptive ... -
Pest science in Pasteur’s Quadrant
(Journal article; Peer reviewed, 2023)More than 25 years ago, Donald Stokes argued that we must move beyond the false dichotomy of basic or applied research and suggested that when considering a program of scientific research it is important to ask whether (i) ... -
Pesticides Induce Oxidative Stress in Zebrafish Embryo
(Master thesis, 2014-06-02)Aquaculture is an industry in rapid global growth. The increased demand and therefore production of aquacultural goods is bound to drain natural marine resources if fish are to continue being fed feeds based solely on ... -
The pH sensitivity of Aqp0 channels in tetraploid and diploid teleosts
(Peer reviewed; Journal article, 2015)Water homeostasis and the structural integrity of the vertebrate lens is partially mediated by AQP0 channels. Emerging evidence indicates that external pH may be involved in channel gating. Here we show that a tetraploid ...
