Robustness of linear mixed-effects models to violations of distributional assumptions
(Peer reviewed; Journal article, 2020)Linear mixed-effects models are powerful tools for analysing complex datasets with repeated or clustered observations, a common data structure in ecology and evolution. Mixed-effects models involve complex fitting procedures ... -
Meeting the challenges of wild boar hunting in a modern society: The case of France
(Peer reviewed; Journal article, 2023)Modern hunting is an ambivalent practice, torn between leisure and labor. Nowhere are these conflicting dimensions better manifested than for wild boar—a simultaneous game and pest species in many countries. Here, we ... -
Direct georeferencing for Hyperspectral Imaging of ocean surface
(Peer reviewed; Journal article, 2023)This paper presents a low-cost, low-weight setup for aerial imaging spectroscopy and an effective methodology for direct georeferencing onto the sea surface. The algorithm and the miniaturized payload described in this ... -
Unmanned vehicle and hyperspectral imager for a more rapid microplastics sampling and analysis.
(Journal article, 2023)In this paper, we present a proof-of-concept study aiming to improve the sampling and analysis of microplastics (MPs) by implementing a novel methodology combining an autonomous surface vehicle and a near-infrared hyperspectral ... -
Advancing Methods for Sampling and Analysis of Microplastics in the Marine Environment
(Doctoral theses at NTNU;2024:24, Doctoral thesis, 2024)Plastic pollution is one of many growing anthropogenic stressors in the marine environment, and its proliferation and effects are not fully understood. Research reporting abundance of plastic debris in the environment is ... -
Effects of gadolinium (Gd) and a Gd-based contrast agent (GBCA) on early life stages of zebrafish (Danio rerio)
(Peer reviewed; Journal article, 2023)Gadolinium (Gd) is one of the rare earth elements (REY) and is widely used in magnetic resonance imaging (MRI) contrast agents. Anthropogenic Gd enrichment has frequently been found in wastewater treatment plant effluents ... -
Recommendations for quantitative uncertainty consideration in ecology and evolution
(Peer reviewed; Journal article, 2023)Ecological and evolutionary studies are currently failing to achieve complete and consistent reporting of model-related uncertainty. We identify three key barriers – a focus on parameter-related uncertainty, obscure ... -
The role of seasonal migration in spatial population synchrony
(Peer reviewed; Journal article, 2023)Spatially synchronized population dynamics are common in nature, and understanding their causes is key for predicting species persistence. A main driver of synchrony between populations of the same species is shared ... -
Data for characterization of the optical properties of Atlantic salmon (Salmo salar) blood
(Peer reviewed; Journal article, 2023)Photoplethysmography is a recent addition to physio-logging in Atlantic salmon which can be used for pulse oximetry provided that the properties for light propagation in salmon tissues are known. In this work, optical ... -
Modellering av heildekkande utbreiingskart for arter: Bakgrunn, konsept og arbeidsflyt
(NTNU Gjærevollsenteret;1/2024, Research report, 2024)Ei heilskapleg kartlegging av naturverdiar er avgjerande for ei kunnskapsbasert forvalting av natur. Avvegingar mellom naturverdiar og andre samfunnsinteresser kan ikkje gjerast verken på internasjonalt, nasjonalt, regionalt ... -
A paleogenomic investigation of overharvest implications in an endemic wild reindeer subspecies
(Peer reviewed; Journal article, 2024)Overharvest can severely reduce the abundance and distribution of a species and thereby impact its genetic diversity and threaten its future viability. Overharvest remains an ongoing issue for Arctic mammals, which due to ... -
Photophysiologically active green, red, and brown macroalgae living in the Arctic Polar Night
(Peer reviewed; Journal article, 2023)Abstract: Arctic macroalgae species have developed different growth strategies to survive extreme seasonal changes in irradiance in polar regions. We compared photophysiological parameters such as the light saturation ... -
Targeting Cytosolic Phospholipase A2 alpha (cPLA2α) in Hematological Cancers and Inflammation
(Doctoral theses at NTNU;2023:409, Doctoral thesis, 2023)Cytosolic phospholipase A2 alpha (cPLA2α) is an enzyme that plays a crucial role in regulating the balance between cellular growth and death by releasing the unsaturated fatty acid arachidonic acid from membrane lipids. ... -
Mechanisms and evolution of thermal tolerance in fish
(Doctoral theses at NTNU;2023:392, Doctoral thesis, 2023)Global temperatures are rising and heat waves are becoming more frequent, reaching higher temperatures, and lasting longer. Many animals are living close to their limits for warming tolerance and mass mortality events are ... -
Experimental Assessment of the Environmental Impact of Ethanolamine
(Chapter, 2021)The environmental impact of ethanolamine, a common amine for carbon dioxide capture, was experimentally investigated in laboratory scale microcosms. By exposing the plant-soil systems to varying amounts of ethanolamine, ... -
Describing posterior distributions of variance components: Problems and the use of null distributions to aid interpretation
(Peer reviewed; Journal article, 2023)1. Assessing the biological relevance of variance components estimated using Markov chain Monte Carlo (MCMC)-based mixed-effects models is not straightforward. Variance estimates are constrained to be greater than zero and ... -
Moon phase and season alter road use by lions
(Peer reviewed; Journal article, 2023)Roads within protected areas facilitate management and tourism but can also alter animal movements and foraging opportunities. Animal tracks observed along roads are also used to index species distributions and abundance. ... -
A species-level trait dataset of bats in Europe and beyond
(Peer reviewed; Journal article, 2023)Knowledge of species’ functional traits is essential for understanding biodiversity patterns, predicting the impacts of global environmental changes, and assessing the efficiency of conservation measures. Bats are major ... -
Circular economy for aquatic food systems: insights from a multiscale phosphorus flow analysis in Norway
(Peer reviewed; Journal article, 2023)As wild-caught fish become scarce, feed ingredients for farming fish, such as salmon, are increasingly sourced from agricultural plants that depend on mineral fertilizers. Since these fish are naturally carnivorous, they ... -
Notes on Early Land Plants Today. 82. Frullanoides chinantlana (Gottsche) comb. nov., an older name for Frullanoides tristis (Steph.) van Slageren
(Peer reviewed; Journal article, 2023)Frullanoides tristis (Steph.) van Slageren is a well-established taxon and the name has been used frequently since the revision of the genus by van Slageren (1985). But there is a nomenclature problem with the name as van ...
