A pain-causing and paralytic ant venom glycopeptide
(Journal article; Peer reviewed, 2021)Ants (Hymenoptera: Formicidae) are familiar inhabitants of most terrestrial environments. Although we are aware of the ability of many species to sting, knowledge of ant venom chemistry remains limited. Herein, we describe ... -
A paleogenomic investigation of overharvest implications in an endemic wild reindeer subspecies
(Peer reviewed; Journal article, 2024)Overharvest can severely reduce the abundance and distribution of a species and thereby impact its genetic diversity and threaten its future viability. Overharvest remains an ongoing issue for Arctic mammals, which due to ... -
PAMP-INDUCED SECRETED PEPTIDE 3 (PIP3) modulates immunity in Arabidopsis thaliana
(Journal article; Peer reviewed, 2019)Small post-translationally modified peptides are important signalling components of plant defence responses against phytopathogens, acting both as positive and negative modulators. PAMP-INDUCED SECRETED PEPTIDE (PIP) 1 and ... -
Paper product production identified as the main source of per- and polyfluoroalkyl substances (PFAS) in a Norwegian lake: Source and historic emission tracking
(Peer reviewed; Journal article, 2020)The entirety of the sediment bed in lake Tyrifjorden, Norway, is contaminated by per- and polyfluoroalkyl substances (PFAS). A factory producing paper products and a fire station were investigated as possible sources. Fire ... -
Paraprobiotics and postbiotics of probiotic lactobacilli, their positive effects on the host and action mechanisms: A review
(Peer reviewed; Journal article, 2020)Lactobacilli comprise an important group of probiotics for both human and animals. The emerging concern regarding safety problems associated with live microbial cells is enhancing the interest in using cell components and ... -
Parasite escape through trophic specialization in a species flock
(Journal article, 2017)Adaptive radiation occurs when species diversify rapidly to occupy an array of ecological niches. As opportunities for parasite infection and transmission may greatly vary among these niches, adaptive radiation is expected ... -
Parasite prevalence increases with temperature in an avian metapopulation in northern Norway
(Peer reviewed; Journal article, 2019)Climate and weather conditions may have substantial effects on the ecology of both parasites and hosts in natural populations. The strength and shape of the effects of weather on parasites and hosts are likely to change ... -
Parasite–copepod interactions in Svalbard: diversity, host specificity, and seasonal patterns
(Peer reviewed; Journal article, 2022)Copepods of the genera Calanus and Pseudocalanus are important components of Arctic marine ecosystems. Despite the key roles of these zooplankters, little is known about the organisms they interact with most intimately, ... -
Participatory monitoring drives biodiversity knowledge in global protected areas
(Peer reviewed; Journal article, 2023)Protected areas are central in strategies to conserve biodiversity. Effective area-based conservation relies on biodiversity data, but the current biodiversity knowledge base is insufficient and limited by geographic and ... -
Particle characterization and influence on the nauplii and egg production of calanoid copepod (Acartia tonsa Dana) in water treatment systems with and without membrane filtration
(Master thesis, 2014)The calanoid copepod Acartia tonsa has been demonstrated to be able to replace the Artemia or rotifer for marine fish larvae due to its excellent nutrient, wide range of temperature and salinity tolerance and capability ... -
Partikkelutslipp fra skiferindustri i Drivavassdraget. Undersøkelser av påvirkning på fisk og bunndyr.
(NINA rapport;1040, Research report, 2014)Drivavassdraget har bestander av sjøvandrende laksefisk på en om lag 85 kilometer lang elvestrekning mellom Sunndalsøra og absolutt vandringshinder 580 meter over havet i Drivdalen. Etter at lakseparasitten Gyrodactylus ... -
Paths towards greater consensus building in experimental biology
(Peer reviewed; Journal article, 2022)In a recent editorial, the Editors-in-Chief of Journal of Experimental Biology argued that consensus building, data sharing, and better integration across disciplines are needed to address the urgent scientific challenges ... -
Pathways of Lipid Metabolism in Marine Algae, Co-Expression Network, Bottlenecks and Candidate Genes for Enhanced Production of EPA and DHA in Species of Chromista
(Journal article; Peer reviewed, 2013)The importance of n-3 long chain polyunsaturated fatty acids (LC-PUFAs) for human health has received more focus the last decades, and the global consumption of n-3 LC-PUFA has increased. Seafood, the natural n-3 LC-PUFA ... -
Pattern and distribution of human-elephant conflicts in three conflict-prone landscapes in Myanmar
(Peer reviewed; Journal article, 2021)Human-elephant conflicts (HEC) are detrimental for both humans and elephants. A better understanding of HEC enhances effective mitigation strategies and promotes the wellbeing of humans and wild elephants. This study ... -
Patterns and Drivers of Phylogenetic Diversity and Endemism in the Norwegian Vascular Flora
(Master thesis, 2018)Biodiversity is commonly measured as the local abundance of discrete species. This approach fails to incorporate evolutionary relationships among species and gives an incomplete picture of the diversity in a given region. ... -
Patterns and relationships of the distribution of arctic and boreal forest herbivores: A three-dimensional approach.
(Master thesis, 2019)Biodiversity is a complex concept that presents three primary facets: genetic, species and ecological diversity. However, biodiversity is usually viewed and valued in terms of the number of discrete species present. This ... -
Patterns in spatial and temporal variation in population abundances of vertebrates
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:163, Doctoral thesis, 2013)In this thesis I investigate the heterogeneity of population abundance by using the Taylor’s power law relationship of mean and variance, in time and space. Within the framework of stochastic population dynamics, the ... -
