The look of agricultural landscapes – How do non-crop landscape elements contribute to visual preferences in a large-scale agricultural landscape?
(Peer reviewed; Journal article, 2020-04-27)Efficiency in agricultural food production has long been in focus and this has affected the spatial structure of agricultural land use. One outcome has been extensive criticism based on a wide range of negative consequences, ... -
Lophodermium spp.
(Grønn kunnskap e;7(101R) 2003, Research report, 2003)Lophodermium spp. fører til nålefall på fleire bartreartar. På furu er L. seditiosum (ekte furuskytte) den viktigaste årsaka til at furunåler fell av for tidleg. -
Loss of species and genetic diversity during colonization: Insights from acanthocephalan parasites in northern European seals
(Peer reviewed; Journal article, 2023-10-19)Studies on host–parasite systems that have experienced distributional shifts, range fragmentation, and population declines in the past can provide information regarding how parasite community richness and genetic diversity ... -
Losses and grass silage quality in bunker silos compacted by tractor versus wheel loader
(Peer reviewed; Journal article, 2020-04-27)The study aimed to explore whether an increase in bunker silage density obtained by turning to a heavier packing machine than a farm size tractor would reduce losses and improve grass silage quality and aerobic stability. ... -
Low genetic variation of invasive Fallopia spp. in their northernmost European distribution range
(Journal article; Peer reviewed, 2017)Knowledge about the reproduction strategies of invasive species is fundamental for effective control. The invasive Fallopia taxa (Japanese knotweed s.l.) reproduce mainly clonally in Europe, and preventing spread of ... -
Low precipitation due to climate change consistently reduces multifunctionality of urban grasslands in mesocosms
(Peer reviewed; Journal article, 2023-02-03)Urban grasslands are crucial for biodiversity and ecosystem services in cities, while little is known about their multifunctionality under climate change. Thus, we investigated the effects of simulated climate change, i.e., ... -
Low temperature treatment affects concentration and distribution of Chrysanthemum stunt viroid in Argyranthemum
(Journal article; Peer reviewed, 2016)Chrysanthemum stunt viroid (CSVd) can infect Argyranthemum and cause serious economic loss. Low temperature treatment combined with meristem culture has been applied to eradicate viroids from their hosts, but without success ... -
Low-cost investment with high quality performance. Bleaching earths for phosphorus reduction in the low-temperature bleaching process of rapeseed oil
(Peer reviewed; Journal article, 2020-05-08)Rapeseed oils are a valuable component of the diet. Mostly, there are refined oils deprived of valuable nutrients in the market, hence in recent times cold-pressed and unrefined oils have been available and popular among ... -
Luftegård til økologiske okser - anbefalinger for utforming og bruk
(Bioforsk TEMA;5(24) 2010, Research report, 2010-12)Innen økologisk landbruk er man generelt opptatt av dyrevelferd og å gi dyrene mulighet til naturlig atferd. Det er derfor et krav i det økologiske regelverket at alle storfe inkludert okser skal ha permanent tilgang på ... -
