European pollen reanalysis, 1980–2022, for alder, birch, and olive
(Journal article; Peer reviewed, 2024)The dataset presents a 43 year-long reanalysis of pollen seasons for three major allergenic genera of trees in Europe: alder (Alnus), birch (Betula), and olive (Olea). Driven by the meteorological reanalysis ERA5, the ... -
Metals and other trace elements in plasma and feathers of seabirds breeding in Svalbard
(Peer reviewed; Journal article, 2024)We assessed the concentrations of metals and other trace elements in two of the most common seabird species breeding on Svalbard, the black-legged kittiwake (Rissa tridactyla) and the Brünnich's guillemot (Uria lomvia). ... -
Next Generation Thiazolyl Ketone Inhibitors of Cytosolic Phospholipase A2 α: from Synthesis to Chemotherapeutic Mechanism of Action
(Journal article; Peer reviewed, 2025)Eicosanoids regulate the pathologies of inflammation and carcinogenesis and limiting their production by inhibiting group IVA cytosolic phospholipase A2 (cPLA2α) is a potential approach to cancer treatment. Here we report ... -
Genetic Regulation of Diatom Photosynthesis
(Chapter, 2024)Diatoms (Bacillariophyceae) are considered to be the most diverse class of algae, including as many as 250 genera and having possibly as many as 200,000 species. Because of their complex evolutionary history, they are ... -
Rare earth elements and yttrium (REY) in fjord waters: Comparison between seawater in the Trondheimfjord (Norway), its local riverine REY sources and the North Atlantic
(Journal article; Peer reviewed, 2024)The rare earth elements and yttrium (REY) are critical resources increasingly released into the environment due to their pivotal role for an ever-growing number of high-tech products and processes. Fjords, worldwide and ... -
High Capacity for Physiological Plasticity Occurs at a Slow Rate in Ectotherms
(Journal article; Peer reviewed, 2025)Phenotypic plasticity enables organisms to express a phenotype that is optimal in their current environment. The ability of organisms to obtain the optimum phenotype is determined by their (i) capacity for plasticity, which ... -
“Influence of short-to-continuous and continuous photoperiods combined with elevated temperatures on sexual maturation in lumpfish (Cyclopterus lumpus, L. 1758)”
(Journal article; Peer reviewed, 2025)We tested the photothermal effects on sexual maturation in the broodstock of lumpfish (Cyclopterus lumpus) using short-to-continuous (LDL) and continuous (LL) photoperiods for 24 weeks, with temperature elevation during ... -
Bayesian marker-based principal component ridge regression – a flexible multipurpose framework for quantitative genetics in wild study systems
(Journal article, 2024)As larger genomic data sets become available for wild study populations, the need for flexible and efficient methods to estimate and predict quantitative genetic parameters, such as the adaptive potential and measures for ... -
On the importance of scale in evolutionary quantitative genetics
(Peer reviewed; Journal article, 2024)The informed use of scales and units in evolutionary quantitative genetics is often neglected, and naïve standardizations can cause misinterpretations of empirical results. A potentially influential example of such neglect ... -
Occurrence, bioaccumulation and trophic dynamics of per- and polyfluoroalkyl substances in two tropical freshwater lakes
(Journal article; Peer reviewed, 2024)We have investigated the occurrence, distribution, and biomagnification of per- and polyfluoroalkyl substances (PFAS) in two tropical lakes (Asejire and Eleyele) of Southwestern Nigeria, with contrasting urban intensities. ... -
Get it while it's hot: Benefits of a large herbivore exploiting stochastic resource pulses in a time of food scarcity
(Peer reviewed; Journal article, 2024)To persist in seasonal environments, animals track, exploit, and store energy when food is plentiful. Seasonal changes in plant phenology that are predictable allow animals to track abundant food resources. However, little ... -
Modelling heterogeneity in the classification process in multi-species distribution models can improve predictive performance
(Journal article; Peer reviewed, 2024)Species distribution models and maps from large-scale biodiversity data are necessary for conservation management. One current issue is that biodiversity data are prone to taxonomic misclassifications. Methods to account ... -
Ancient reindeer mitogenomes reveal island-hopping colonisation of the Arctic archipelagos
(Peer reviewed; Journal article, 2024)Climate warming at the end of the last glacial period had profound effects on the distribution of cold-adapted species. As their range shifted towards northern latitudes, they were able to colonise previously glaciated ... -
The role of indirect interspecific effects in the stochastic dynamics of a simple trophic system
(Journal article; Peer reviewed, 2024)Indirect interspecific effects (IIEs) occur when one species affects another through a third intermediary species. Understanding the role of IIEs in population dynamics is key for predicting community-level impacts of ... -
Zeaxanthin epoxidase 3 Knockout Mutants of the Model Diatom Phaeodactylum tricornutum Enable Commercial Production of the Bioactive Carotenoid Diatoxanthin
(Peer reviewed; Journal article, 2024)Carotenoids are pigments that have a range of functions in human health. The carotenoid diatoxanthin is suggested to have antioxidant, anti-inflammatory and chemo-preventive properties. Diatoxanthin is only produced by a ... -
The Genetic Architecture of Recombination Rates is Polygenic and Differs between the Sexes in Wild House Sparrows (Passer domesticus)
(Journal article; Peer reviewed, 2024)Meiotic recombination through chromosomal crossing-over is a fundamental feature of sex and an important driver of genomic diversity. It ensures proper disjunction, allows increased selection responses, and prevents mutation ... -
Role of niche and micro-habitat preferences in per- and polyfluoroalkyl substances occurrence in the gills of tropical lake fish species
(Peer reviewed; Journal article, 2024)The present study has investigated per- and poly-fluoroalkyl substances (PFAS) in the gill tissues of various fish species inhabiting different trophic levels within Eleyele Lake, a tropical freshwater lake in Nigeria. The ... -
Biomass estimations of cultivated kelp using underwater RGB images from a mini-ROV and computer vision approaches
(Peer reviewed; Journal article, 2024)Seaweed farming is the fastest-growing aquaculture sector worldwide. As farms continue to expand, automated methods for monitoring growth and biomass become increasingly important. Imaging techniques, such as Computer ... -
Toxic and Genotoxic Effects of Ibuprofen and PFOS, singly and in combination. Evaluated in Allium cepa Root Chromosomal Aberration Assay
(Master thesis, 2024)Vannforurensning er i dag en alvorlig miljøtrussel. Til tross for sterk regulering, slippes millioner av tonn giftige stoffer ut i naturlige vannkilder hver dag, noe som forårsaker massiv vannforurensning. De mest relevante ... -
Evaluation of stress in farmed Atlantic salmon (Salmo salar) using different biological matrices
(Journal article; Peer reviewed, 2024)Atlantic salmon were subjected to an acute crowding scenario, and their subsequent stress responses were observed under three distinct swimming speed/water flow (WF) conditions: 0.5, 1, and 1.5 body lengths per second ...
