Pollen-based quantitative reconstructions of Holocene regional vegetation cover (plant-functional types and land-cover types) in Europe suitable for climate modelling.
(Peer reviewed; Journal article, 2014-10-22)We present quantitative reconstructions of regional vegetation cover in north-western Europe, western Europe north of the Alps, and eastern Europe for five time windows in the Holocene [around 6k, 3k, 0.5k, 0.2k, and 0.05k ... -
Pollen-chemistry variations along elevation gradients and their implications for a proxy for UV-B radiation in the plant-fossil record
(Journal article; Peer reviewed, 2021)Research indicates that phenolic compounds (e.g. para-coumaric acid) found within pollen grains may be useful as a proxy to reconstruct the UV-B radiation received at the Earth's surface in the geological past. However, ... -
Pollination as an ecosystem service in Lofthus, Norway: A study on the distribution of wild and managed pollinators on apple crops and how they are affected by the surrounding landscape
(Master thesis, 2014-09-04)Pollination is an important ecosystem service that benefits human welfare by increasing the quantity and quality of fruit and seed set of many crops. The decline in bee abundance and diversity in recent years may result ... -
A polybasic motif in ErbB3-binding protein 1 (EBP1) has key functions in nucleolar localization and polyphosphoinositide interaction
(Peer reviewed; Journal article, 2016-07)Polyphosphoinositides (PPIns) are present in the nucleus where they participate in crucial nuclear processes, such as chromatin remodelling, transcription and mRNA processing. In a previous interactomics study, aimed to ... -
Polycyclic aromatic hydrocarbons modulate the activity of Atlantic cod (Gadus morhua) vitamin D receptor paralogs in vitro
(Journal article; Peer reviewed, 2021)Vitamin D receptor (VDR) mediates the biological function of the steroid hormone calcitriol, which is the metabolically active version of vitamin D. Calcitriol is important for a wide array of physiological functions, ... -
Polymastiidae (Demospongiae: Hadromerida) with ornamented exotyles: a review of morphological affinities and description of a new genus and three new species
(Peer reviewed; Journal article, 2016)All polymastiid sponges displaying ornamented exotyles are reviewed and their morphological affinities are reconsidered. The study embraces all known species of Proteleia, Sphaerotylus, Trachyteleia and Tylexocladus as ... -
Polyphosphoinositides in the nucleus: Roadmap of their effectors and mechanisms of interaction
(Peer reviewed; Journal article, 2019)Biomolecular interactions between proteins and polyphosphoinositides (PPIn) are essential in the regulation of the vast majority of cellular processes. Consequently, alteration of these interactions is implicated in the ... -
Polystyrene nanoplastics enhance the toxicological effects of DDE in zebrafish (Danio rerio) larvae
(Journal article; Peer reviewed, 2023)Anthropogenic releases of plastics, persistent organic pollutants (POPs), and heavy metals can impact the environment, including aquatic ecosystems. Nanoplastics (NPs) have recently emerged as pervasive environmental ... -
Pond greenhouse gas emissions controlled by duckweed coverage
(Journal article; Peer reviewed, 2022-10-05)Freshwaters are significant contributors of greenhouse gases to the atmosphere, including carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). Small waterbodies such as ponds are now recognized to have disproportionate ... -
Population dynamics and characteristics of Klebsiella pneumoniae from healthy poultry in Norway
(Journal article; Peer reviewed, 2023-05-18)Klebsiella pneumoniae is an important opportunistic pathogen widely studied in relation to human infection and colonization. However, there is a lack of knowledge regarding other niches that K. pneumoniae may inhabit. K. ... -
Population genetic structure of the glacier lanternfish, Benthosema glaciale (Myctophidae) in Norwegian waters
(Peer reviewed; Journal article, 2001)It is hypothesised that the fjords with restricted water circulation may partially isolate fish populations living there. The pelagic life history stages of the mesopelagic lanternfish may potentially subject to dispersal ... -
Population Genetic Structure of the Spotted Wolffish, Anarhichas minor, in the North Atlantic
(Peer reviewed; Journal article, 2008) -
Population genetics of Saccharina latissima (sugar kelp) in Norway
(Master thesis, 2019-05-01)The interest in cultivating sugar kelp, Saccharina latissima in Norway is increasing and therefore knowledge about the population genetics of this species is important. A total of 345 samples were genotyped from sixteen ... -
Population processes in cyber system variability
(Journal article; Peer reviewed, 2022)Variability is inherent to cyber systems. Here, we introduce ideas from stochastic population biology to describe the properties of two broad kinds of cyber systems. First, we assume that each of N0 components can be in ... -
Population structure and dynamics of Atlantic herring. A case study of herring inhabiting marginal habitats in Landvikvannet and its vicinity
(Doctoral thesis, 2018-05-04)Knowledge about the structure and dynamics of marine fish populations is essential for their conservation and management to maintain biodiversity and population complexity. Atlantic herring (Clupea harengus) is one of the ... -
Population structure of European sprat (Sprattus sprattus) in the Greater North Sea ecoregion revealed by otolith shape analysis
(Journal article; Peer reviewed, 2022)A successful discrimination of fish populations is essential for sustainable management and assessment. Otolith shape analysis has been used on several species to reveal their population structure. Our aim was to use the ... -
The population structure of roundnose grenadier (Coryphaenoides rupestris) in southwestern Norway
(Master thesis, 2017-05-30)Ocean circulation, bathymetric barriers, and ecological processes can hinder the dispersal of marine fishes and thus generate sub-populations. The present study investigated the population structure of a benthopelagic fish, ... -
