Pan-genome survey of the fish pathogen Yersinia ruckeri links accessory- and amplified genes to virulence
(Journal article; Peer reviewed, 2023)While both virulent and putatively avirulent Yersinia ruckeri strains exist in aquaculture environments, the relationship between the distribution of virulence-associated factors and de facto pathogenicity in fish remains ... -
A pan-Himalayan test of predictions on plant species richness based on primary production and water-energy dynamics
(Journal article; Peer reviewed, 2021)Spatial variation in plant species diversity is well-documented but an overarching first-principles theory for diversity variation is lacking. Chemical energy expressed as Net Primary Production (NPP) is related to a ... -
Pancrustacean Evolution Illuminated by Taxon-Rich Genomic-Scale Data Sets with an Expanded Remipede Sampling
(Peer reviewed; Journal article, 2019-07-04)The relationships of crustaceans and hexapods (Pancrustacea) have been much discussed and partially elucidated following the emergence of phylogenomic data sets. However, major uncertainties still remain regarding the ... -
Pankreassykdom; en gjennomgang av dagens kunnskaper, rapporter, tiltak og forvaltning.
(Master thesis, 2013-10-16)Pankreassykdom (PD) er en svært smittsom virussykdom som opptrer hos Atlantisk laks (Salmo salar L.) og regnbueørret (Oncorhynchus mykiss) i oppdrett. PD forårsakes av salmonid alphavirus (SAV). Hensikten med denne oppgaven ... -
The pantophysin gene and its relationship with survival in early life stages of Atlantic cod: Pantophysin in Atlantic cod
(Journal article; Peer reviewed, 2020)Genetic markers are widely used in fisheries management around the world. While the genetic structure and markers selected are usually based on samples from the wild, very few controlled experiments have been carried out ... -
Parasite development affect dispersal dynamics; infectivity, activity and energetic status in cohorts of salmon louse copepodids
(Journal article; Peer reviewed, 2020)The salmon louse, Lepeophtheirus salmonis, is a parasitic copepod infecting wild and farmed salmonid fishes in the northern hemisphere. It has a direct lifecycle with a planktonic dispersal phase and an infective copepodid ... -
Parasite intensity is driven by temperature in a wild bird
(Peer reviewed; Journal article, 2019)Increasing awareness that parasitism is an essential component of nearly all aspects of ecosystem functioning, as well as a driver of biodiversity, has led to rising interest in the consequences of climate change in terms ... -
Parasites Found in Pink Salmon (Oncorhynchus gorbuscha) Caught in the Feeding Areas in the Norwegian Sea
(Master thesis, 2021-06-01)The pink salmon (Oncorhynchus gorbuscha) is native to the North Pacific but has repeatedly been introduced to the North Atlantic by Russian researchers since 1956. This has resulted in the establishment of populations in ... -
Parent-offspring conflict over reproductive timing: ecological dynamics far away and at other times may explain spawning variability in Pacific herring
(Peer reviewed; Journal article, 2019)Timing of reproduction may be of crucial importance for fitness, particularly in environments that vary seasonally in food availability or predation risk. However, for animals with spatially separated feeding and breeding ... -
Parma consensus statement on metabolic disruptors
(Peer reviewed; Journal article, 2015-06-20)A multidisciplinary group of experts gathered in Parma Italy for a workshop hosted by the University of Parma, May 16–18, 2014 to address concerns about the potential relationship between environmental metabolic disrupting ... -
PARP-1: A novel polyphosphoinositide effector protein
(Master thesis, 2020-06-19)Polyphosphoinositides (PPIns) are a family of seven signalling lipids that are important for many cellular processes. While their functional roles in the cytoplasm have been extensively studied, their roles in the nucleus ... -
Participatory mapping reveals biocultural and nature values in the shared landscape of a Nordic UNESCO Biosphere Reserve
(Journal article; Peer reviewed, 2022)Making the right decisions for sustainable development requires sound knowledge of the values and spatial distribution of the services co-produced by ecosystems and people. UNESCO's Man and the Biosphere programme and ... -
Particle detection and tracking with DNA
(Journal article; Peer reviewed, 2022)We present the first proof-of-concept simulations of detectors using biomaterials to detect particle interactions. The essential idea behind a “DNA detector” involves the attachment of a forest of precisely-sequenced single ... -
Pasteurella atlantica in Norwegian lumpsuckers : Characterisation, pathogenicity, vaccine development and immune responses
(Doctoral thesis, 2021-12-16)Lumpsuckers (Cyclopterus lumpus L.) have gained popularity as a cleaner fish to biologically control salmon lice infestations in farmed Atlantic salmon in Norway. Starting in 2012, most producers in Norway have been raising ... -
Pasteurella spp. Infections in Atlantic salmon and lumpsucker
(Journal article; Peer reviewed, 2021)The use of cleaner fish as a delousing method in Norwegian salmonid aquaculture has increased tremendously over the last few years. This has led to the emergence of a new large industry of farming lumpsuckers (Cyclopterus ... -
Pathogen screening in Semi Closed Containment Systems and open net pens with emphasis on the presence of Tenacibaculum spp. and development of Real Time RT- PCR assays for Tenacibaculum spp.
(Master thesis, 2021-06-07)Tenacibaculosis, caused by Tenacibaculum spp., has been an increasing problem in Norwegian Salmon farming causing reduced fish welfare and significant economic losses. Semi Closed Containment System (SCCS) is a rather new ... -
