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 ... -
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 ... -
Pathology of experimentally induced mouthrot caused by Tenacibaculum maritimum in Atlantic salmon smolts
(Peer reviewed; Journal article, 2018-11-01)Mouthrot, caused by Tenacibaculum maritimum is a significant disease of farmed Atlantic salmon, Salmo salar on the West Coast of North America. Smolts recently transferred into saltwater are the most susceptible and affected ... -
Pathways of Carbon Assimilation and Ammonia Oxidation Suggested by Environmental Genomic Analyses of Marine Crenarchaeota
(Peer reviewed; Journal article, 2006-03-21)Marine Crenarchaeota represent an abundant component of oceanic microbiota with potential to significantly influence biogeochemical cycling in marine ecosystems. Prior studies using specific archaeal lipid biomarkers and ... -
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 ... -
