Varied diets, including broadleaved forage, are important for a large herbivore species inhabiting highly modified landscapes
(Peer reviewed; Journal article, 2020-02-05)Diet quality is an important determinant of animal survival and reproduction, and can be described as the combination of different food items ingested, and their nutritional composition. For large herbivores, human landscape ... -
Vegetables and social relations in Norway and the Netherlands: A comparative analysis of urban allotment gardeners
(Journal article; Peer reviewed, 2018-03-01)This article aims to explore differences in motivation for and actual use of allotment gardens. Results from questionnaire surveys and semistructured interviews in two Norwegian and one Dutch garden show that growing ... -
Vegetation modulates the impact of climate extremes on gross primary production
(Peer reviewed; Journal article, 2021-01-05)Drought and heat events affect the uptake and sequestration of carbon in terrestrial ecosystems. Factors such as the duration, timing, and intensity of extreme events influence the magnitude of impacts on ecosystem processes ... -
Vernalization Requirement and the Chromosomal VRN1-Region can Affect Freezing Tolerance and Expression of Cold-Regulated Genes in Festuca pratensis
(Journal article; Peer reviewed, 2016-02-25)Plants adapted to cold winters go through annual cycles of gain followed by loss of freezing tolerance (cold acclimation and deacclimation). Warm spells during winter and early spring can cause deacclimation, and if ... -
Vertically divergent responses of SOC decomposition to soil moisture in a changing climate
(Peer reviewed; Journal article, 2022-01-09)The role of soil moisture for organic matter decomposition rates remains poorly understood and underrepresented in Earth System Models (ESMs). We apply the Dual Arrhenius Michaelis-Menten (DAMM) model to a selection of ESM ... -
Viability of Embryo Sacs and Fruit Set in Different Plum (Prunus domestica L.) Cultivars Grown under Norwegian Climatic Conditions
(Peer reviewed; Journal article, 2022-01-14)Compatibility and synchrony between specialized tissues of the pistil, female gametophytes and male gametophytes, are necessary for successful pollination, fertilization, and fruit set in angiosperms. The aim of the present ... -
Vitality and in vitro pollen germination of different ‘Oblačinska’ sour cherry clones
(Journal article; Peer reviewed, 2017)Vitality of pollen, in vitro pollen germination and pollen tube growth (pollen tube length and pollen tube growth rate) were investigated in Oblačinska sour cherry in order to determine the differences between clones which ... -
Volatile Organic Compound Profiles From Wheat Diseases Are Pathogen-Specific and Can Be Exploited for Disease Classification
(Peer reviewed; Journal article, 2022-01-07)Plants and fungi emit volatile organic compounds (VOCs) that are either constitutively produced or are produced in response to changes in their physico-chemical status. We hypothesized that these chemical signals could be ... -
Vulnerability and resilience of the carbon exchange of a subarctic peatland to an extreme winter event
(Journal article; Peer reviewed, 2018-06-01)Extreme winter events that damage vegetation are considered an important climatic cause of arctic browning—a reversal of the greening trend of the region—and possibly reduce the carbon uptake of northern ecosystems. ... -

Warmer temperature during asexual reproduction induce methylome, transcriptomic, and lasting phenotypic changes in Fragaria vesca ecotypes
(Peer reviewed; Journal article, 2023-07-31)Plants must adapt with increasing speed to global warming to maintain their fitness. One rapid adaptation mechanism is epigenetic memory, which may provide organisms sufficient time to adapt to climate change. We studied ... -
Wastewater-aged silver nanoparticles in single and combined exposures with titanium dioxide affect the early development of the marine copepod Tisbe battagliai
(Peer reviewed; Journal article, 2020-08-27)In this study, the effects of aged Ag and TiO2 NPs, individually and as a mixture, in wastewater relative to their pristine counterparts on the development of the copepod nauplii (Tisbe battagliai) were investigated. NP ... -
Water sorption in wood cell walls–data exploration of the infuential physicochemical characteristics
(Peer reviewed; Journal article, 2022-12-07)The material properties of wood are intimately tied to the amount of moisture contained in the wood cell walls. The moisture content depends on the environmental conditions, i.e. temperature and relative humidity, but also ... -
Water up-take in fuel pellets studied by Dynamic Vapour Sorption (DVS) analysis and its potential role in self-heating during storage
(Journal article; Peer reviewed, 2018-10-11)The self-heating of wood fuel pellets is a well-recognised problem causing fire incidents in the storage of the pellets as well as severe intoxication of workers by elevated carbon monoxide and carbon dioxide levels and ... -
Weather Patterns Associated with DON Levels in Norwegian Spring Oat Grain: A Functional Data Approach
(Peer reviewed; Journal article, 2021-12-27)Fusarium graminearum is regarded as the main deoxynivalenol (DON) producer in Norwegian oats, and high levels of DON are occasionally recorded in oat grains. Weather conditions in the period around flowering are reported ... -
Weathering kinetics of thin wood veneers assessed with near infrared spectroscopy
(Journal article; Peer reviewed, 2016)Wooden elements may be subjected to mechanical, environmental or biological alterations during their service life. The most susceptible parts of wood structural members are the exposed surfaces since they are subjected to ... -
Weed suppression greatly increased by plant diversity in intensively managed grasslands: A continental-scale experiment
(Journal article; Peer reviewed, 2018-03)1. Grassland diversity can support sustainable intensification of grassland production through increased yields, reduced inputs and limited weed invasion. We report the effects of diversity on weed suppression from 3 years ... -
Weed-Competitive Ability of Teff (Eragrostis tef (Zucc.) Trotter) Varieties
