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 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 ... -
Lophozia lantratovae Bakalin new to northern Europe

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 ... -
Loss of CpFTSY Reduces Photosynthetic Performance and Affects Insertion of PsaC of PSI in Diatoms
(Peer reviewed; Journal article, 2023)The chloroplast signal recognition particle (CpSRP) receptor (CpFTSY) is a component of the CpSRP pathway that post-translationally targets light-harvesting complex proteins (LHCPs) to the thylakoid membranes in plants and ... -
Loss of the arabidopsis protein kinases ANPs affects root cell wall composition, and triggers the cell wall damage syndrome
(Journal article; Peer reviewed, 2018)The Arabidopsis NPK1-related Protein kinases ANP1, ANP2 and ANP3 belong to the MAP kinase kinase kinase (MAPKKK) superfamily and were previously described to be crucial for cytokinesis, elicitor-induced immunity and ... -
Low genetic diversity despite multiple introductions of the invasive plant species Impatiens glandulifera in Europe
(Journal article; Peer reviewed, 2015)Background Invasive species can be a major threat to native biodiversity and the number of invasive plant species is increasing across the globe. Population genetic studies of invasive species can provide key insights ... -
Low impact of first-time spawners on population growth in a brown trout population
(Peer reviewed; Journal article, 2021)For species with individual variation in reproductive success, experience in breeding and the distribution of different breeders is important for population productivity and viability. Human impacts, such as climate change ... -
Low intestinal inflammation model (HP48) in Atlantic salmon (Salmo salar) and inflammatory mitigation by Bactocell
(Peer reviewed; Journal article, 2022)Moderate levels of intestinal damage and inflammation are often seen in intensive fish aquaculture. The causes may be due to antinutrients from plant meals, stress or other causes. There is currently a lack of good models ... -
Low- and High-Volume of Intensive Endurance Training Significantly Improves Maximal Oxygen Uptake after 10-Weeks of Training in Healthy Men
(Journal article; Peer reviewed, 2013)Regular exercise training improves maximal oxygen uptake (VO2max), but the optimal intensity and volume necessary to obtain maximal benefit remains to be defined. A growing body of evidence suggests that exercise training ... -
Lower survival probability of house sparrows severely infected by the gapeworm parasite
(Journal article; Peer reviewed, 2014)The effect of parasites in natural populations has received increasing attention in recent years. Studies have shown that parasites may play an important part in population ecology due to their potential effects on host ... -
Lower trophic level mixed fishery (LOTROMIX) - Implications for ecosystem and management
