Long-term dynamics, population structure and connectivity of the helmet jellyfish Periphylla periphylla in a Norwegian fjord and adjacent waters
(Journal article; Peer reviewed, 2023)Mass occurrences of Periphylla periphylla in Norwegian fjords cause major concerns related to potential regime shifts that could affect ecosystem stability. 15 years of trawl data (2006–2015), complemented with comprehensive ... -
Long-term Effects of Seeding in an Alpine Environment: and a comparison of the effect of native Festuca ovina and non-native Festuca rubra on the establishment of native Betula nana
(Master thesis, 2011)As human induced disturbance in alpine ecosystems have increased, more knowledge is needed about the long-term effects of restoration efforts in such environments. There are benefits with using native species in restoration ... -
Long-term Effects of Shifts in Grazing Pressure on Alpine Plant Species along an Elevational Gradient
(Master thesis, 2015)Sheep (Ovis aries) are the main large herbivore in Norwegian mountains during summer and these herbivores have shaped alpine plant communities over a long land-use history. Sheep are selective feeders, and increased livestock ... -
Long-term exposure to elevated carbon dioxide does not alter activity levels of a coral reef fish in response to predator chemical cues
(Journal article; Peer reviewed, 2017)Levels of dissolved carbon dioxide (CO2) projected to occur in the world’s oceans in the near future have been reported to increase swimming activity and impair predator recognition in coral reef fishes. These behavioral ... -
Long-term herbivore removal experiments reveal how geese and reindeer shape vegetation and ecosystem CO2-fluxes in high-Arctic tundra
(Peer reviewed; Journal article, 2023)1. Given the current rates of climate change, with associated shifts in herbivore population densities, understanding the role of different herbivores in ecosystem functioning is critical for predicting ecosystem responses. ... -
Long-term microbial community structures and dynamics in a commercial RAS during seven production batches of Atlantic salmon fry (Salmo salar)
(Peer reviewed; Journal article, 2023)The microbiota of recirculating aquaculture systems (RAS) is of major importance for optimal fish health. However, the microbial communities in commercial RAS are highly complex and more knowledge is needed to potentially ... -
Long-term performance of highly selective carbon hollow fiber membranes for biogas upgrading in the presence of H<inf>2</inf>S and water vapor
(Peer reviewed; Journal article, 2022)Biogas is an increasingly attractive renewable resource that needs to be upgraded to meet either the natural gas pipeline quality or the biomethane requirement. The use of carbon membranes is a promising alternative to ... -
Long-term prediction of fish growth under varying ambient temperature using a multiscale dynamic model
(Journal article; Peer reviewed, 2009)Background: Feed composition has a large impact on the growth of animals, particularly marine fish. We have developed a quantitative dynamic model that can predict the growth and body composition of marine fish for a ... -
Long-term stability of screen-printed pseudo-reference electrodes for electrochemical biosensors
(Journal article; Peer reviewed, 2018)Pseudo reference electrodes forms an essential part of electrochemical transducers, where they are used to maintain a reference potential for the system. Yet, little is known about their long-term stability, and any drift ... -
Long-term trends in elephant mortality and their causes in Kenya
(Peer reviewed; Journal article, 2022)High mortality poses a serious threat to sustainable conservation of the African elephant (Loxodonta africana). Using detected carcass data collected by the Kenya Wildlife Service (KWS) during 1992-2017, we analyze temporal ... -
Longitudinal and secular trends in total cholesterol levels and impact of lipid-lowering drug use among Norwegian women and men born in 1905–1977 in the population-based Tromsø Study 1979–2016
(Journal article; Peer reviewed, 2017)Objectives Elevated blood cholesterol is a modifiable risk factor for cardiovascular disease. Cholesterol level surveillance is necessary to study population disease burden, consider priorities for prevention and intervention ... -
Longitudinal telomere dynamics within natural lifespans of a wild bird
(Peer reviewed; Journal article, 2023)Telomeres, the nucleotide sequences that protect the ends of eukaryotic chromosomes, shorten with each cell division and telomere loss may be influenced by environmental factors. Telomere length (TL) decreases with age in ... -
Looking for alien invertebrates in Norwegian ports, extensive sampling, and precise identification
(Master thesis, 2020)Fremmedarter er sammen med klimaendringer, tap av habitat, overhøsting og forurensning de mest alvorlige truslene globalt mot biologisk mangfold. I det marine miljø spres arter blant annet gjennom internasjonal skipstrafikk ... -
Looking for the Big Picture:Genome-Based Approaches to Improve Alginate Production in Azotobacter vinelandii
(Doktoravhandlinger ved NTNU, 1503-8181; 2014:18, Doctoral thesis, 2014)Alginates are commercially important polysaccharides with a wide range of industrial and technological applications. Polymer chain length and monomer distribution greatly affect the material properties, which makes different ... -

Losing the 'arms race': Multiresistant salmon lice are dispersed throughout the North Atlantic Ocean
(Journal article; Peer reviewed, 2021)Nothing lasts forever, including the effect of chemicals aimed to control pests in food production. As old pesticides have been compromised by emerging resistance, new ones have been introduced and turned the odds back in ... -
Loss Measurements in Silicon Core Optical Waveguides
(Master thesis, 2013)Silicon core fibers have, because of their non-linear optical properties and transmission in the IR, recently been the focus of several different research groups. At NTNU, a new method for production of silicon fibers has ... -
Loss of ALBINO3b insertase results in truncated light-harvesting antenna in diatoms
(Journal article; Peer reviewed, 2019)The family of chloroplast ALBINO3 (ALB3) proteins function in the insertion and assembly of thylakoid membrane protein complexes. Loss of ALB3b in the marine diatom Phaeodactylum tricornutum leads to a striking change of ... -
