Pollen evidence of variations in Holocene climate and Southern Hemisphere Westerly Wind strength on sub- Antarctic South Georgia
(Journal article; Peer reviewed, 2021)The Southern Hemisphere Westerlies (SHW) play a major role in the global climate system. The winds drive ocean circulation and affect the Southern Oceans’ ability to take up atmospheric CO2. Recently, the SHW core belt has ... -
Pollen-based climate reconstruction techniques for late Quaternary studies
(Journal article; Peer reviewed, 2020)Fossil pollen records are well-established indicators of past vegetation changes. The prevalence of pollen across environmental settings including lakes, wetlands, and marine sediments, has made palynology one of the most ... -
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, ... -

Pollinating bees in fruit orchards of Western Norway: 1. Where the Wild Bees Are: Exploring how the landscape context influences the abundance and diversity of wild bees visiting apple orchards 2.The foraging preference and behavior of managed and wild bees in apple and pear orchards
(Master thesis, 2022-03-14)1) Abstract. Several studies have found that the presence of natural and semi-natural habitats is beneficial, particularly for wild bees visiting crops. These relatively undisturbed areas provide essential foraging and ... -
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 ... -
Pollination, wild bee communities and seed development in apple orchards of Sogn and Hardanger in Western Norway
(Master thesis, 2022-09-06)Human progression has led to and is still creating massive land use changes. This is the main driver of biodiversity loss, and we are currently living in the sixth mass extinction. Increased human populations need increased ... -
Pollinator conservation requires a stronger and broader application of the precautionary principle
(Journal article; Peer reviewed, 2021)The accumulating scientific evidence on global insect and pollinator decline is fuelling calls for pollinator conservation policies. A broad range of regulating and incentivising policies is undoubtedly needed to address ... -
Polske foreldre i norsk skole: en kvalitativ studie av hjem-skolesamarbeid
(Master thesis, 2013-11-15)As a result of the EU expansion in 2004, a number of Polish labour-immigrants have migrated to Norway. Poles currently make up the largest group of immigrants in the country. In this thesis I have focused on collaboration ... -
Poly-ADP-ribose assisted protein localization resolves that DJ-1, but not LRRK2 or α-synuclein, is localized to the mitochondrial matrix
(Peer reviewed; Journal article, 2019)Several proteins linked to familial Parkinson disease have been associated with mitochondrial (dys-)function and have been described to reside within mitochondria. The putative mitochondrial and sub-mitochondrial localization ... -
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 ... -
Polybios to Pausanias: Arkadian Identity in the Roman Empire
(Papers of the Norwegian Institute at Athens, Chapter, 2005)Many ancient statements about Arkadia date from the Roman period, and most of what we hear from Arkadians themselves, directly from Polybios, and indirectly via Pausanias, belongs in this context. This source material ... -
Polychaetes from Jan Mayen (Annelida, Polychaeta)
(Peer reviewed; Journal article, 2010)A thorough literature review has been undertaken to establish the first complete account of polychaetes recorded from the area around the volcanic island of Jan Mayen. The annotated checklist lists 121 species-level taxa, ... -
Polycrystalline Diamond Coating on Orthopedic Implants: Realization and Role of Surface Topology and Chemistry in Adsorption of Proteins and Cell Proliferation
(Journal article; Peer reviewed, 2022)Polycrystalline diamond has the potential to improve the osseointegration of orthopedic implants compared to conventional materials such as titanium. However, despite the excellent biocompatibility and superior mechanical ... -
Polycyclic aromatic hydrocarbons (PAHs) and their nitrated and oxygenated derivatives in the Arctic boundary layer: Seasonal trends and local anthropogenic influence
(Journal article; Peer reviewed, 2021)A total of 22 polycyclic aromatic hydrocarbons (PAHs), 29 oxy-PAHs, and 35 nitro-PAHs (polycyclic aromatic compounds, PACs) were measured in gaseous and particulate phases in the ambient air of Longyearbyen, the most ... -
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, ... -

Polygenic overlap and shared genetic loci between loneliness, severe mental disorders, and cardiovascular disease risk factors suggest shared molecular mechanisms
(Journal article; Peer reviewed, 2021)Clinical and epidemiological evidence suggest that loneliness is associated with severe mental disorders (SMDs) and increases the risk of cardiovascular disease (CVD). However, the mechanisms underlying the relationship ... -
Polygenic overlap between C-reactive protein, plasma lipids, and Alzheimer disease
(Peer reviewed; Journal article, 2015-06)Background—Epidemiological findings suggest a relationship between Alzheimer disease (AD), inflammation, and dyslipidemia, although the nature of this relationship is not well understood. We investigated whether this ...
