(Peer reviewed; Journal article, 2022-12-22)Cattle production is constantly threatened by diseases like East Coast fever, also known as theileriosis, caused by the protozoan parasite Theileria parva which is transmitted by ticks such as the brown ear tick, Rhipicephalus ... -
Links between profitability, nitrogen surplus, greenhouse gas emissions, and energy intensity on organic and conventional dairy farms
(Journal article; Peer reviewed, 2018-11-18)This study examines the relationships between profitability, nitrogen (N) surplus, greenhouse gas emissions (GHG), and energy intensity and factors influencing these relationships in dairy farming. In-depth data from 10 ... -
Linoleic Acid Promotes Emission of Bark Beetle Semiochemicals by Fungal Symbionts
(Peer reviewed; Journal article, 2022-12-30)Tree-killing bark beetles in conifer forests vector symbiotic fungi that are thought to help the beetles kill trees. Fungal symbionts emit diverse volatile blends that include bark beetle semiochemicals involved in mating ... -
Living inside termites: an overview of symbiotic interac-tions, with emphasis on flagellate protists
(Journal article; Peer reviewed, 2017)To degrade lignocellulose efficiently, lower termites rely on their digestive tract’s specific features (i.e., hysiological properties and enzymes) and on the network of symbiotic fauna harboured in their hindgut. This ... -
Local resources, linear elements and mass-flowering crops determine bumblebee occurrences in moderately intensified farmlands
(Journal article; Peer reviewed, 2017)There is consensus that land-use change is a main driver behind the recent declines of many pollinator populations in Europe. However, it is still not adequately understood how the local resource quality and landscape ... -
Localized Agri-Food Systems and Biodiversity
(Journal article; Peer reviewed, 2018-02-02)Interest in localized agri-food systems has grown significantly in recent years. They are associated with several benefits and are seen as important for rural development. An important share of the academic debate addresses ... -
Long term effects of ionising radiation in the Chernobyl Exclusion zone on DNA integrity and chemical defence systems of Scots pine (Pinus sylvestris)
(Peer reviewed; Journal article, 2023-12-15)The Chernobyl Nuclear Power Plant (ChNPP) accident in 1986 resulted in extremely high levels of acute ionising radiation, that killed or damaged Scots pine (Pinus sylvestris) trees in the surrounding areas. Dead trees were ... -
Long-term changes (1990–2015) in the atmospheric deposition and runoff water chemistry of sulphate, inorganic nitrogen and acidity for forested catchments in Europe in relation to changes in emissions and hydrometeorological conditions
(Journal article; Peer reviewed, 2018-01-12)The international Long-Term Ecological Research Network (ILTER) encompasses hundreds of long-term research/monitoring sites located in a wide array of ecosystems that can help us understand environmental change across the ... -
Long-term effects of environmentally relevant doses of 2,2 ',4,4 ',5,5 ' hexachlorobiphenyl (PCB153) on neurobehavioural development, health and spontaneous behaviour in maternally exposed mice
(Journal article; Peer reviewed, 2011-01-13)Background: Polychlorinated biphenyls (PCBs) are widespread in the environment, human food and breast milk. Seafood is known to contain nutrients beneficial for the normal development and function of the brain, but also ... -
The long-term fate of deposited nitrogen in temperate forest soils
(Peer reviewed; Journal article, 2020-06-20)Increased anthropogenic nitrogen (N) inputs can alter the N cycle and affect forest ecosystem functions. The impact of increased N deposition depends among others on the ultimate fate of N in plant and soil N pools. ... -
Long-term monitoring of protected Cultural Heritage Environments in Norway: Development of methods and first-time application
(Journal article; Peer reviewed, 2019-04-27)Norway has a political goal to minimize the loss of cultural heritage due to removal, destruction or decay. On behalf of the national Directorate for Cultural Heritage, we have developed methods to monitor Cultural Heritage ... -
Long-term preservation of potato leafroll virus, potato virus S, and potato spindle tuber viroid in cryopreserved shoot tips
(Journal article; Peer reviewed, 2018-10-06)Availability of and easy access to diverse plant viruses and viroids is a prerequisite in applied and basic studies related to viruses and viroids. Long-term preservation of viruses and viroids is difficult. A protocol was ... -
Long-term spatiotemporal dynamics in a mountain birch (Betula pubescens ssp. czerepanovii) forest in south-east Norway
