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 ... -
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 ... -
Acetylation of Pinus radiata delays hydrolytic depolymerisation by the brown-rot fungus Rhondonia placenta
(Journal article; Peer reviewed, 2018-11-01)Acetylation of wood can provide protection against wood deteriorating fungi, but the exact degradation me- chanism remains unclear. The aim of this study was to determine the effect of acetylation of Pinus radiata wood ... -
Adjusting the scent ratio: using genetically modified Vitis vinifera plants to manipulate European grapevine moth behaviour
(Journal article; Peer reviewed, 2017-06-02)Herbivorous insects use olfactory cues to locate their host plant within a complex olfactory landscape. One such example is the European grapevine moth Lobesia botrana, a key pest of the grape in the Palearctic region, ... -
Authorization of microbial plant protection products in the Scandinavian countries: a comparative analysis
(Peer reviewed; Journal article, 2020-02-05)The EU has developed a Directive on Sustainable Use of Chemical Pesticides (2009/128/EC) (SUD) that aims to enhance the use of non-chemical alternatives to pesticides like microbial plant protection products (PPP). The ... -
Autumn growth of three perennial weeds at high latitude benefits from climate change
(Peer reviewed; Journal article, 2019)In autumn, agricultural perennial weeds prepare for winter and can store reserves into creeping roots or rhizomes. Little is known about influence of climate change in this period. We tested the effect of simulated climate ... -
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 ... -
Bioinformatic characterisation of the effector repertoire of the strawberry pathogen Phytophthora cactorum
(Journal article; Peer reviewed, 2018-10-02)The oomycete pathogen Phytophthora cactorum causes crown rot, a major disease of cultivated strawberry. We report the draft genome of P. cactorum isolate 10300, isolated from symptomatic Fragaria x ananassa tissue. Our ... -
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 ... -
Chemical characterization of 21 species of marine macroalgae common in Norwegian waters: benefits of and limitations to their potential use in food and feed
(Journal article, 2018-01-18)BACKGROUND: In the past few years, much effort has been invested into developing a new blue economy based on harvesting, cultivating and processing marine macroalgae in Norway. Macroalgae have high potential for a wide ... -
Consistency of impact assessment protocols for non-native species
(Journal article; Peer reviewed, 2019-04-01)Standardized tools are needed to identify and prioritize the most harmful non-native species (NNS). A plethora of assessment protocols have been developed to evaluate the current and potential impacts of non-native species, ... -
Cryopreservation of shallot (Allium cepa var. aggregatum) shoot tips by droplet-vitrification
(Journal article; Peer reviewed, 2019)Shallot (Allium cepa var. aggregatum) is an important vegetable crop belonging to the genus Allium. The present study attempted to develop an efficient droplet-vitrification cryopreservation method for shallot ‘10603’ shoot ... -
Distribution of the Infection Time of Ascospores of Venturia inaequalis
(Journal article; Peer reviewed, 2019-02)In many areas where spring is wet, fungicides are applied in relation to rain events that trigger ejection of ascospores of Venturia inaequalis, which cause primary infections of apple scab. Past studies established the ... -
Effects of bean seed treatment by the entomopathogenic fungi Metarhizium robertsii and Beauveria bassiana on plant growth, spider mite populations and behavior of predatory mites
(Journal article; Peer reviewed, 2019-02-06)The fungal genera Metarhizium and Beauveria are considered as both entomopathogens and endophytes; they are able to colonize a wide variety of plants and can cause increased plant growth and protect plants against pests. ... -
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, ... -
Effects of renewal time, taproot cutting, ploughing practice, false seedbed and companion crop on docks (Rumex spp.) when renewing grassland
(Journal article; Peer reviewed, 2018-12-05)Docks (Rumex spp.) are a considerable problem in grassland production worldwide. We investigated how different cultural management techniques affected dock populations during grassland renewal: (I) renewal time, (II) ... -
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 ... -
Fungal associates of the tree-killing bark beetle, Ips typographus, vary in virulence, ability to degrade conifer phenolics and influence bark beetle tunneling behavior
(Journal article; Peer reviewed, 2018-07-20)The bark beetle Ips typographus carries numerous fungi that could be assisting the beetle in colonizing live Norway spruce (Picea abies) trees. Phenolic defenses in spruce phloem are degraded by the beetle's major tree-killing ... -
