Carbon cycle feedbacks in an idealized simulation and a scenario simulation of negative emissions in CMIP6 Earth system models
(Journal article; Peer reviewed, 2024)Limiting global warming to well below 2 ∘C by the end of the century is an ambitious target that requires immediate and unprecedented emission reductions. In the absence of sufficient near-term mitigation, this target will ... -
Effects of different live feeding regimes on the development and lipid composition of ballan wrasse (Labrus bergylta) larvae
(Master thesis, 2024)Lakselus (Lepeophtheirus salmonis) utgjør en av de største utfordringene for utvidelsen av norsk lakseoppdrett, og påvirker produksjonen, fiskevelferden og villaksbestandene negativt. Effektiviteten til både kjemiske og ... -
Evaluating hyperspectral Secchi depth retrieval through hybrid modeling and regression
(Peer reviewed; Journal article, 2023)This work compares different regression models combined with hybrid modeling to estimate water clarity using hyper-spectral remote sensing data. The Secchi depth, a proxy of water clarity, can be modeled using first ... -
Towards a circular phosphorus economy in Norway - Strategies for integrating agriculture and aquaculture at multiple scales
(Research report, 2023)Phosphorus is a building block for all life and therefore plays an essential role in food production. Currently, large amounts of phosphorus enter the Norwegian food system from abroad in the form of mineral fertilizer, ... -
Radiative forcing geoengineering causes higher risk of wildfires and permafrost thawing over the Arctic regions
(Journal article; Peer reviewed, 2024)Radiative forcing geoengineering is discussed as an intermediate solution to partially offset greenhouse gas-driven warming by altering the Earth’s energy budget. Here we use an Earth System Model to analyse the response ... -
Life history traits and demography of a mountain bird under climatic variation
(Doctoral theses at NTNU;2024:90, Doctoral thesis, 2024)Ongoing climate change can be expected to have major consequences for many species and ecosystems. Effects have been reported on reproduction, survival and movement ecology, with potential impacts for population dynamics ... -
The effect of salmon protein hydrolysate on palatability for Atlantic salmon smolts
(Master thesis, 2024)Krav om bedre fiskevelferd og mer bærekraftig akvakultur gjør det nødvendig å finne nye og bedre fôrressurser. Når man vurderer nye ingredienser til fôr, kan valg av strategi ha stor innvirkning på tolkningen av kvaliteten ... -
Expanding the coverage of regulons from high-confidence prior knowledge for accurate estimation of transcription factor activities
(Peer reviewed; Journal article, 2023)Gene regulation plays a critical role in the cellular processes that underlie human health and disease. The regulatory relationship between transcription factors (TFs), key regulators of gene expression, and their target ... -
Tracing the footprints of Arctic pollution: Spatial variations in toxic and essential elements in Svalbard reindeer (Rangifer tarandus platyrhynchus) faeces
(Journal article; Peer reviewed, 2023)The Arctic is an accumulation zone of long-range transported pollution. In addition, local anthropogenic activities further contribute to regional pollution levels. The Svalbard reindeer (Rangifer tarandus platyrhynchus) ... -
A comprehensive evaluation of predictive performance of 33 species distribution models at species and community levels
(Journal article; Peer reviewed, 2019)A large array of species distribution model (SDM) approaches has been developed for explaining and predicting the occurrences of individual species or species assemblages. Given the wealth of existing models, it is unclear ... -
Per- and poly-fluoroalkyl substances in Tawny Owl (Strix aluco) feathers from Trøndelag, Norway
(Journal article; Peer reviewed, 2023)Per- and polyfluoroalkyl substances (PFASs) are contaminants of global concern due to their ubiquitous occurrence in the environment, bioaccumulation and the adverse effects on organisms. Tawny Owls (Strix aluco) are ... -
Species distributions models may predict accurately future distributions but poorly how distributions change: A critical perspective on model validation
(Journal article; Peer reviewed, 2023)Aim: Species distribution models (SDMs) are widely used to make predictions on how species distributions may change as a response to climatic change. To assess the reli-ability of those predictions, they need to be critically ... -
Subclinical thiamine deficiency results in failed reproduction in Arctic foxes
(Peer reviewed; Journal article, 2024)Thiamine deficiency can result in life-threatening physiological and neurological complications. While a thiamine-deficient diet may result in the onset of such symptoms, the presence of thiaminase – an enzyme that breaks ... -
Multi-generation genetic and fitness effects of immigration in a natural meta-population of song sparrows (Melospiza melodia)
(Doctoral theses at NTNU;2024:105, Doctoral thesis, 2024)Fragmentation leads to smaller habitat patches and population sizes, endangering population fitness and persistence, including through inbreeding depression and loss of genetic diversity. These effects can be mitigated ... -
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 ... -
Notes on Early Land Plants Today. 84. Cheilolejeunea solariae, nom. nov. for Strepsilejeunea subcrenulata Herzog
(Peer reviewed; Journal article, 2023)Grolle (1989) united Strepsilejeunea subcrenulata Herzog with the younger name Cheilolejeunea papillata Solari. However, transferring the former name to Cheilolejeunea was blocked by the existence of the earlier name ... -
Notes on Early Land Plants Today. 83. Re-instatement of Lejeunea parvisaccata
(Peer reviewed; Journal article, 2023)Mizutani (1970) introduced a new name, Lejeunea micholitzii Mizut., when transferring Hygrolejeunea parvisaccata Steph. to Lejeunea Lib. since Lejeunea parvisaccata (Steph.) Steph. was blocking the name in Lejeunea. The ... -
Ecological signals of arctic plant-microbe associations are consistent across eDNA and vegetation surveys
(Peer reviewed; Journal article, 2023)Understanding how different taxa respond to abiotic characteristics of the environment is of key interest for understanding the assembly of communities. Yet, whether eDNA data will suffice to accurately capture environmental ... -
