Phylogeography of Phycodrys rubens (Linnaeus) batters from mainland Norway and Svalbard based on nuclear and mtDNA sequences and microsatellites
(Master thesis, 2014-04-01)Phycodrys rubens is a common cold temperate red macroalga in the North Atlantic, a region with a diverse natural history that has shaped the phylogeography for many species. In this study microsatellite loci as well as ... -
Physical and nutrient stimuli differentially modulate gut motility patterns, gut transit rate, and transcriptome in an agastric fish, the ballan wrasse
(Journal article; Peer reviewed, 2021-02-11)The effects of nutrient and mechanical sensing on gut motility and intestinal metabolism in lower vertebrates remains largely unknown. Here we present the transcriptome response to luminal stimulation by nutrients and an ... -
The physical damage of climbing activity on sandstone lichen cover
(Journal article; Peer reviewed, 2021)Climbing activities affect cliff site species. With cliff sites harbouring unique species communities, the rise in popularity of outdoor climbing activities is a major threat. In this study, we assessed a previously unclimbed ... -
Physical enrichment research for captive fish: Time to focus on the DETAILS
(Journal article; Peer reviewed, 2021)Growing research effort has shown that physical enrichment (PE) can improve fish welfare and research validity. However, the inclusion of PE does not always result in positive effects and conflicting findings have highlighted ... -
Physiological and flesh quality consequences of pre-mortem crowding stress in Atlantic mackerel (Scomber scombrus)
(Journal article; Peer reviewed, 2020-02-13)In commercial wild capture pelagic fisheries it is common practice to crowd catches to high densities to allow efficient pumping onboard. Crowding during the final stages of purse seine capture for small pelagic species ... -
Physiological and molecular mechanisms of oocyte hydration in an evolutionary old teleost, Atlantic herring (Clupea harengus)
(Doctoral thesis, 2008-04-11)This work investigated physiological and molecular mechanisms of oocyte hydration in Atlantic herring (Clupea harengus). Both inorganic and organic solutes were found to be important solutes involved in the hydration ... -
Physiological and molecular responses to environmental pollutants in Atlantic cod (Gadus morhua) : Characterization of the aryl hydrocarbon receptor signaling pathway and underlying mechanisms of crude oil toxicity
(Doctoral thesis, 2021-03-05)Environmental pollutants are harmful substances that can interfere and disrupt numerous physiological processes. Different cellular defence mechanisms are therefore crucial for both detecting pollutants and coordinate the ... -
Physiological characterization of a novel strain within Rhodobacteraceae, isolated from a biofilm sample on a barite chimney at the Loki´s Castle Vent Field.
(Master thesis, 2016-10-03)Strain M was isolated from a biofilm found on top of one of the barite chimney at Loki´s Castle Vent Field (73°30´N and 8°E) in the Norwegian-Greenland Sea. A polyphasic characterization, including physical and phylogenetic ... -
Physiological effects of recapture and transport from net-cages in lumpfish
(Journal article; Peer reviewed, 2022)Lumpfish are widely used for removing sea lice in salmonid sea-based aquaculture. If these fish are to be harvested and used for human consumption, it is necessary to know how the physical strain associated with removing ... -
Physiological response of temperature shocks in turbot and sole
(Peer reviewed; Journal article, 2019)In the present study, selected temperature drops were examined to investigate the effects of live chilling on stress and welfare in turbot and sole. This study demonstrated that rapid temperature drops from 11°C–12°C and ... -
Phytoplankton dynamics in contrasting early stage North Atlantic spring blooms: composition, succession, and potential drivers
(Peer reviewed; Journal article, 2015-04-24)The spring bloom is a key annual event in the phenology of pelagic ecosystems, making a major contribution to the oceanic biological carbon pump through the production and export of organic carbon. However, there is little ... -

Planctomycetes as a Source for Cytotoxic Activity Towards Cancer Cells
(Master thesis, 2021-06-01)Planctomycetes are a ubiquitous phylum in the bacterial domain. They are known to possess unique traits distinguishing them from other bacteria, such as the formation of rosette aggregates, the lack of FtsZ-protein used ... -
Planctomycetes as a Vital Constituent of the Microbial Communities Inhabiting Different Layers of the Meromictic Lake Sælenvannet (Norway)
(Journal article; Peer reviewed, 2020)Meromictic lakes are permanently stratified lakes that display steep gradients in salinity, oxygen and sulphur compounds tightly linked to bacterial community structure and diversity. Lake Sælenvannet is a meromictic lake ... -
Planctomycetes dominate biofilms on surfaces of the kelp Laminaria hyperborea
(Peer reviewed; Journal article, 2010)Background: Bacteria belonging to Planctomycetes display several unique morphological and genetic features and are found in a wide variety of habitats on earth. Their ecological roles in these habitats are still poorly ... -
The planetary biology of cytochrome P450 aromatases
(Peer reviewed; Journal article, 2004-08-17)Background: Joining a model for the molecular evolution of a protein family to the paleontological and geological records (geobiology), and then to the chemical structures of substrates, products, and protein folds, is ... -
Planktivorous fish and environmental change: using mechanistic modelling to explore the underpinnings and general validity of expected responses
(Doctoral thesis, 2020-03-13)The living conditions of marine and terrestrial organisms are currently changing at a rapid pace due to human activities. To predict how this will affect them, and hence to develop appropriate management and conservation ... -
Plant dispersal characteristics shape the relationship of diversity with area and isolation
(Journal article; Peer reviewed, 2022)Aim The relation of plant dispersal syndromes with insular species richness patters remains one of the challenges in island biogeography, especially as people have affected species distribution patterns. This study ... -
Plant dispersal in a changing climate. A seed-rain study along climate gradients in Southern Norway
(Master thesis, 2012-10-14)Seed dispersal is a key event in a plant's life, affecting the outcomes of many ecological processes ranging from species reproduction to population and community dynamics. It is influenced by various environmental and ... -
Plant macrofossil evidence for an early onset of the Holocene summer thermal maximum in northernmost Europe
(Peer reviewed; Journal article, 2015-04-10)Holocene summer temperature reconstructions from northern Europe based on sedimentary pollen records suggest an onset of peak summer warmth around 9,000 years ago. However, pollen-based temperature reconstructions are ...
