Mass spectrometry reveals the presence of specific set of epigenetic DNA modifications in the Norway spruce genome
(Journal article; Peer reviewed, 2019-12-17)5-Methylcytosine (5mC) is an epigenetic modification involved in regulation of gene expression in metazoans and plants. Iron-(II)/α-ketoglutarate-dependent dioxygenases can oxidize 5mC to 5-hydroxymethylcytosine (5hmC), ... -
In vitro therapies for virus elimination of potato-valuable germplasm in Norway
(Journal article; Peer reviewed, 2019-01-25)Potato (Solanum tuberosum L.) is one of the most important crops grown in Norway, and virus-free plants are required for commercial potato production and for preservation of potato germplasm. The present study evaluates ... -
Entomopathogenic fungal conidia marginally affect the behavior of the predators Orius majusculus (Hemiptera: Anthocoridae) and Phytoseiulus persimilis (Acari: Phytoseiidae) foraging for healthy Tetranychus urticae (Acari: Tetranychidae)
(Journal article; Peer reviewed, 2019-11-20)We determined how conidia of arthropod-pathogenic fungi on leaves affected the behavior of two predators—Orius majusculus (Hemiptera: Anthocoridae) and Phytoseiulus persimilis (Acari: Phytoseiidae)—when offered a choice ... -
Belowground Biodiversity Relates Positively to Ecosystem Services of European Forests
(Journal article; Peer reviewed, 2019-03-19)Biodiversity of ecosystems is an important driver for the supply of ecosystem services to people. Soils often have a larger biodiversity per unit surface area than what can be observed aboveground. Here, we present what ... -
Effects of mild drought on the morphology of sun and shade needles in 20-year-old Norway spruce trees
(Journal article; Peer reviewed, 2019-02-28)Several studies have looked at how individual environmental factors influence needle morphology in conifer trees, but interacting effects between drought and canopy position have received little attention. In this study, ... -
Forewarned is forearmed: harmonized approaches for early detection of potentially invasive pests and pathogens in sentinel plantings
(Journal article; Peer reviewed, 2019-06-21)The number of invasive alien pest and pathogen species affecting ecosystem functioning, human health and economies has increased dramatically over the last decades. Discoveries of invasive pests and pathogens previously ... -
A Dual-Permeability Approach for Modeling Soil Water Flow and Heat Transport during Freezing and Thawing
(Journal article; Peer reviewed, 2019-08-22)Preferential flow may become significant in partially frozen soils because infiltration can occur through large, initially air-filled pores surrounded by a soil matrix with limited infiltration capacity. The objectives of ... -
Can aphids be controlled by fungus? A mathematical model
(Journal article; Peer reviewed, 2019-06-21)The control of insect pests in agriculture is essential for food security. Chemical controls typically damage the environment and harm beneficial insects such as pollinators, so it is advantageous to identify targetted ... -
A comprehensive phylogeographic study of Arion vulgaris Moquin-Tandon, 1855 (Gastropoda: Pulmonata: Arionidae) in Europe
(Journal article; Peer reviewed, 2019-12-17)Arion vulgaris Moquin-Tandon, 1855 is regarded as one of the 100 most invasive species in Europe. The native distribution range of this species is uncertain, but for many years, the Iberian Peninsula has been considered ... -
Identification of QTLs for powdery mildew (Podosphaera aphanis; syn. Sphaerotheca macularis f. sp. fragariae) susceptibility in cultivated strawberry (Fragaria ×ananassa)
(Journal article; Peer reviewed, 2019-09-19)Strawberry powdery mildew (Podosphaera aphanis Wallr.) is a pathogen which infects the leaves, fruit, stolon and flowers of the cultivated strawberry (Fragaria ×ananassa), causing major yield losses, primarily through ... -
Impacts of soil moisture level and organic matter content on growth of two Juncus species and Poa pratensis grown under acid soil conditions
(Journal article; Peer reviewed, 2019)The abundance of Juncus effusus (soft rush) and Juncus conglomeratus (compact rush) has increased in coastal grasslands in Norway over recent decades, and their spread has coincided with increased precipitation in the ... -
Skogskader – en kunnskapssammenstilling
(NIBIO Rapport;, Research report, 2019-12)I Europa er det registrert økende omfang av skogskader de siste hundre år, og klimaendringer er identifisert som en viktig driver bak økningene i for eksempel vindskader, barkbilleangrep og skogbranner. Det er likevel store ... -
Effect of three isolates of Pandora neoaphidis from a single population of Sitobion avenae on mortality, speed of kill and fecundity of S. avenae and Rhopalosiphum padi at different temperatures
(Journal article; Peer reviewed, 2019)We studied the effect of three Pandora neoaphidis isolates from one Sitobion avenae population, three temperatures, and two aphid species namely S. avenae and Rhopalosiphum padi on (i) aphid mortality, (ii) time needed to ... -

Leaching of Five Pesticides of Contrasting Mobility through Frozen and Unfrozen Soil
(Journal article; Peer reviewed, 2019)Field and laboratory studies show increased leaching of pesticides through macropores in frozen soil. Fast macropore flow has been shown to reduce the influence of pesticide properties on leaching, but data on these processes ... -
Metabolic cold acclimation of 'Polka' and 'Honeoye' strawberries under natural field conditions
(Journal article; Peer reviewed, 2014)The winter hardiness of strawberry varieties used in perennial production systems varies greatly. Still, little information is available on how plant metabolism adapts to cold and freezing temperatures under natural ... -
