A data-derived reference mixture representative of European wastewater treatment plant effluents to complement mixture assessment
(Journal article; Peer reviewed, 2023)Aquatic environments are polluted with a multitude of organic micropollutants, which challenges risk assessment due the complexity and diversity of pollutant mixtures. The recognition that certain source-specific background ... -
Spatial cumulant models enable spatially informed treatment strategies and analysis of local interactions in cancer systems
(Peer reviewed; Journal article, 2023)Theoretical and applied cancer studies that use individual-based models (IBMs) have been limited by the lack of a mathematical formulation that enables rigorous analysis of these models. However, spatial cumulant models ... -
Biomonitoring of rare earth elements in Southern Norway: Distribution, fractionation, and accumulation patterns in the marine bivalves Mytilus spp. and Tapes spp.
(Peer reviewed; Journal article, 2023)Growing extraction and usage of rare earth elements and yttrium (REY) for medical and industrial applications has resulted in increased discharges into the marine environment. Using Mytilus spp. Mussels and Tapes spp. clams ... -
Neural representation of goal direction in the monarch butterfly brain
(Peer reviewed; Journal article, 2023)Neural processing of a desired moving direction requires the continuous comparison between the current heading and the goal direction. While the neural basis underlying the current heading is well-studied, the coding of ... -
Acclimation capacity of critical thermal maximum varies among populations: Consequences for estimates of vulnerability
(Peer reviewed; Journal article, 2023)Adaptive plasticity in thermal tolerance traits may buffer organisms against changing temperatures, making such responses of particular interest in the face of global climate change. Although population variation is integral ... -
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. ... -
