Elevational treeline and forest line dynamics in Norwegian mountain areas - a review
(Journal article; Peer reviewed, 2018)Purpose Treelines and forest lines (TFLs) have received growing interest in recent decades, due to their potential role as indicators of climate change. However, the understanding of TFL dynamics is challenged by the complex ... -
Elucidation of the molecular responses during the primary infection of wild blueberry phenotypes with Monilinia vaccinii-corymbosi under field conditions
(Peer reviewed; Journal article, 2021-10-27)Background Monilinia blight caused by Monilinia vaccinii-corymbosi (Reade) Honey (M.vc) is a major disease of wild blueberry that can result in severe crop losses in the absence of an integrated disease management programme. ... -
Emerging stability of forest productivity by mixing two species buffers temperature destabilizing effect
(Peer reviewed; Journal article, 2022-08-06)The increasing disturbances in monocultures around the world are testimony to their instability under global change. Many studies have claimed that temporal stability of productivity increases with species richness, although ... -
Endogeneity, heterogeneity, and determinants of inefficiency in Norwegian crop-producing farms
(Journal article; Peer reviewed, 2018-04-27)This paper addresses the endogeneity of inputs and output (which is mostly ignored in the stochastic frontier (SF) literature) in the SF panel data model under the behavioural assumption that firms maximize returns to the ... -
Endophytic fungi improve management of the burrowing nematode in banana (Musa spp.) through enhanced expression of defence-related genes
(Peer reviewed; Journal article, 2023-03-02)The root-burrowing nematode, Radopholus similis, is reputedly the most damaging nematode pest of banana and responsible for major production losses. In this study, the endophytic potential of 13 fungal isolates was assessed ... -
Endophytic Non-Pathogenic Fusarium oxysporum-Derived Dual Benefit for Nematode Management and Improved Banana (Musa spp.) Productivity
(Peer reviewed; Journal article, 2022-01-18)The banana weevil (Cosmopolites sordidus) and the burrowing nematode Radopholus similis represent two of the most important pests of bananas. Previously, colonization of banana plants by the non-pathogenic Fusarium oxysporum ... -
Enhancing plant N uptake with biochar-based fertilizers: limitation of sorption and prospects
(Peer reviewed; Journal article, 2022-03-24)Background Biochar-based fertilizer products (BCF) have been reported to increase both crop yield and N-use efficiency. Such positive effects are often assumed to result from the slow-release of N adsorbed on BCF structures. ... -
Enhancing pollination is more effective than increased conventional agriculture inputs for improving watermelon yields
(Peer reviewed; Journal article, 2020-04-23)Agricultural practices to improve yields in small‐scale farms in Africa usually focus on improving growing conditions for the crops by applying fertilizers, irrigation, and/or pesticides. This may, however, have limited ... -
Enrichment of the protein content of the macroalgae Saccharina latissima and Palmaria palmata
(Peer reviewed; Journal article, 2022-04-30)The large brown seaweeds (kelps) are potential sources of protein for animal feed. They have lower protein contents than most red and green algae, but due to potential for large-scale production, they may represent a ... -
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 ... -
Entreprenørskap i Norge - mest for menn?
(Journal article; Peer reviewed, 2013)I Norge er bare én av fire entreprenører kvinner. I denne artikkelen benytter vi administrative registerdata til å lete etter årsaker til dette kjønnsgapet. Vi finner at ulikhet i kvinners og menns bransjetilhørighet kan ... -
