Late-Autumn Ramet Sprouting of Three Arable Creeping Perennial Weed Species
(Peer reviewed; Journal article, 2022-09-13)Elymus repens (L.) Gould), Cirsium arvense (L.) Scop. and Sonchus arvensis L. are important arable creeping perennial weeds in Europe. These are clonal plants with subterranean reproductive organs (E. repens, rhizomes, the ... -
Leachability and Decay Resistance of Wood Polyesterified with Sorbitol and Citric Acid
(Peer reviewed; Journal article, 2020-06-06)Research Highlights: Polyesterification of wood with sorbitol and citric acid (SCA) increases decay resistance against brown-rot and white-rot fungi without reducing cell wall moisture content but the SCA polymer is susceptible ... -
Leachate emissions of short- and long-chain perand polyfluoralkyl substances (PFASs) from various Norwegian landfills
(Journal article; Peer reviewed, 2019)Restrictions on the use of long-chain per- and polyfluoralkyl substances (PFASs) has led to substitutions with short-chain PFASs. This study investigated the presence of four short-chain PFASs and twenty-four long-chain ... -
Leaching and surface runoff after fall application of fungicides on putting greens
(Peer reviewed; Journal article, 2020-12-08)Many greenkeepers and authorities are concerned about the environmental risks resulting from pesticide use on golf courses. We studied leaching and surface runoff of fungicides and metabolites during two winter seasons ... -
Leaching of Five Pesticides of Contrasting Mobility through Frozen and Unfrozen Soil
(Journal article; Peer reviewed, 2019)Field and laboratory studies show increased leaching of pesticides through macropores in frozen soil. Fast macropore flow has been shown to reduce the influence of pesticide properties on leaching, but data on these processes ... -
Learning for Sustainability in Horticultural Production in Arctic Norway
(Peer reviewed; Journal article, 2021-09-20)Sustainability learning is gaining popularity as an important field within sustainability research, where farm sustainability can be understood as a learning process. In this study, we seek to reveal the sustainability ... -
Learning science during teatime: Using a citizen science approach to collect data on litter decomposition in Sweden and Austria
(Peer reviewed; Journal article, 2020-09-18)The decay of organic material—litter decomposition—is a critical process for life on Earth and an essential part of the global carbon cycle. Yet, this basic process remains unknown to many citizens. The Tea Bag Index (TBI) ... -
Legacy of agrochemicals in the circular food economy: Glyphosate-based herbicides introduced via manure fertilizer affect the yield and biochemistry of perennial crop plants during the following year
(Peer reviewed; Journal article, 2022-09-13)Conventional agricultural practices favoring the use of glyphosate-based herbicides (GBHs) increase the risk of GBH residues ending up in animal feed, feces, and, eventually, manure. The use of poultry manure as organic ... -
Lettuce-produced hepatitis C virus E1E2 heterodimer triggers immune responses in mice and antibody production after oral vaccination
(Journal article; Peer reviewed, 2017)The hepatitis C virus (HCV) is a major etiologic agent for severe liver diseases ( e.g . cirrhosis, fibrosis and hepatocellular carcinoma). Approximately 140 million people have chronic HCV infections and about 500 000 die ... -
Life cycle assessment of tomato production for different production strategies in Norway
(Peer reviewed; Journal article, 2022-08-30)The availability of fresh vegetables grown in greenhouses under controlled conditions throughout the year has given rise to concerns about their impact on the environment. In high latitude countries such as Norway, greenhouse ... -
Life-cycle assessment to unravel co-benefits and trade-offs of large-scale biochar deployment in Norwegian agriculture
(Peer reviewed; Journal article, 2022-01-20)Limiting temperature rise below 2 °C requires large deployment of Negative Emission Technologies (NET) to capture and store atmospheric CO2. Compared to other types of NETs, biochar has emerged as a mature option to store ... -
Light exposure of roots in aeroponics enhances the accumulation of phytochemicals in aboveground parts of the medicinal plants Artemisia annua and Hypericum perforatum
(Peer reviewed; Journal article, 2023-01-19)Light acts as a trigger to enhance the accumulation of secondary compounds in the aboveground part of plants; however, whether a similar triggering effect occurs in roots is unclear. Using an aeroponic setup, we investigated ... -
Light-controlled flavonoid biosynthesis in fruits
(Journal article; Peer reviewed, 2014)Light is one of the most important environmental factors affecting flavonoid biosynthesis in plants. The absolute dependency of light to the plant development has driven evolvement of sophisticated mechanisms to sense and ... -
Lignification and cell wall thickening of ray parenchyma cells in Scots pine sapwood
(Peer reviewed; Journal article, 2021-05-26)Scots pine exhibits variations in ray anatomy, which are poorly understood. Some ray parenchyma cells develop thick and lignified cell walls before heartwood formation. We hypothesized that some stands and trees show high ... -
Limits in reaching the anhydrous state of wood and cellulose
(Peer reviewed; Journal article, 2023-06-01)Water-sorption studies and certain organic chemistry reactions require water removal from cellulosic samples. This is hindered by the strong interaction of cellulosic materials with water, and it remains uncertain if a ... -
Linking spatial distribution of Rhipicephalus appendiculatus to climatic variables important for the successful biocontrol by Metarhizium anisopliae in Eastern Africa
(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 ... -
