Arenicolidae (Annelida) in Norwegian waters: Species occurrence, bathymetric distribution and identification of juvenile specimens
(Journal article; Peer reviewed, 2024)The two species of Arenicolidae, Arenicola marina and Arenicolides ecaudata, are common along the Norwegian coast. Juveniles and anterior fragments are often encountered when grab sampling, making traditional morphological ... -
A holo-omics analysis shows how sugar kelp can boost gut health in Atlantic salmon
(Peer reviewed; Journal article, 2024)The projected growth of Aquaculture requires continuous optimisation of feeding regimes, especially in enhancing disease resilience through immunostimulating feed supplements. Seaweed has been introduced as a promising ... -
Corroborating written history with ancient DNA: The case of the Well-man described in an Old Norse saga
(Journal article; Peer reviewed, 2024)The potential of ancient DNA analyses to provide independent sources of information about events in the historical record remains to be demonstrated. Here we apply palaeogenomic analysis to human remains excavated from a ... -
Host-gut microbiota interactions shape parasite infections in farmed Atlantic salmon
(Journal article; Peer reviewed, 2024)Animals and their associated microbiota share long evolutionary histories. However, it is not always clear how host genotype and microbiota interact to affect phenotype. We applied a hologenomic approach to explore how ... -
Lebertia litoralis sp. nov. a new water mite described on morphological and molecular characters (Acariformes, Hydrachnidia, Lebertiidae)
(Peer reviewed; Journal article, 2024)An integrative taxonomic approach, combining new morphological data with the analysis of partial COI sequences (DNA-barcodes) is used to describe Lebertia litoralis Zawal & Szenejko sp. nov. from lake habitats in Poland ... -
Effectiveness of conservation measures to support biodiversity in boreal timber-production forests
(Journal article; Peer reviewed, 2024)Large parts of the boreal forest ecosystems have been greatly affected by human use, and the current timber-oriented forest management practice that dominates boreal forests is proven to cause biodiversity and ecosystem ... -
Future of DNA-based insect monitoring
(Journal article, 2023)Insects are crucial for ecosystem health but climate change and pesticide use are driving massive insect decline. To mitigate this loss, we need new and effective monitoring techniques. Over the past decade there has been ... -
Marine migration, thermal habitat use and feeding habits of Arctic charr (Salvelinus alpinus (L. 1758)) in SW Greenland
(Peer reviewed; Journal article, 2024)Climate change is altering northern coastal aquatic habitats, especially in fjords. Data on current ecosystem structure and biodiversity in many northern fjord and coastal ecosystems, especially for Greenland, are lacking. ... -
Cryptic species diversity and eDNA metabarcoding in marine ecosystem monitoring
(Doctoral theses at NTNU;2024:343, Doctoral thesis, 2024)English summary Marine sediments constitute the largest ecosystem on Earth, yet they remain poorly studied. With increasing human activities in the coastal zone, these understudied environments face unprecedented pressures ... -
Environmental drivers of food webs in charr and trout-dominated cold-water lakes
(Peer reviewed; Journal article, 2024) -
Climate change vulnerability of Arctic char across Scandinavia
(Journal article; Peer reviewed, 2024)Climate change is anticipated to cause species to shift their ranges upward and poleward, yet space for tracking suitable habitat conditions may be limited for range-restricted species at the highest elevations and latitudes ... -
Effects of cattle and cervids on plants and flower-visiting insects in young spruce plantations
(Peer reviewed; Journal article, 2024) -
Linked Selection and Gene Density Shape Genome-Wide Patterns of Diversification in Peatmosses
(Journal article; Peer reviewed, 2024)Genome evolution under speciation is poorly understood in nonmodel and nonvascular plants, such as bryophytes—the largest group of nonvascular land plants. Their genomes are structurally different from angiosperms and ... -
Genomic context determines the effect of DNA methylation on gene expression in the gut epithelium of Atlantic salmon (Salmo salar)
(Peer reviewed; Journal article, 2024)The canonical view of DNA methylation, a pivotal epigenetic regulation mechanism in eukaryotes, dictates its role as a suppressor of gene activity, particularly within promoter regions. However, this view is being challenged ... -
Social and genetic connectivity despite ecological variation in a killer whale network
(Peer reviewed; Journal article, 2024)Philopatric kin-based societies encourage a narrow breadth of conservative behaviours owing to individuals primarily learning from close kin, promoting behavioural homogeneity. However, weaker social ties beyond kin, and ... -
The oral microbiota of wild bears in Sweden reflects the history of antibiotic use by humans
(Peer reviewed; Journal article, 2021)Following the advent of industrial-scale antibiotic production in the 1940s,1 antimicrobial resistance (AMR) has been on the rise and now poses a major global health threat in terms of mortality, morbidity, and economic ... -
Typification of Jungermannia pinguis L. (Marchantiophyta, Aneuraceae)

National records of 3000 European bee and hoverfly species: A contribution to pollinator conservation
(Peer reviewed; Journal article, 2023)1. Pollinators play a crucial role in ecosystems globally, ensuring the seed production of most flowering plants. They are threatened by global changes and knowledge of their distribution at the national and continental ... -
Genomic analyses show extremely perilous conservation status of African and Asiatic cheetahs (Acinonyx jubatus)
(Peer reviewed; Journal article, 2022)We live in a world characterized by biodiversity loss and global environmental change. The extinction of large carnivores can have ramifying effects on ecosystems like an uncontrolled increase in wild herbivores, which in ... -
The effect of surveillance fishing on migration distance of Atlantic Salmon during the spawning period
(Peer reviewed; Journal article, 2024)Objective Surveillance fishing surveys can be performed to estimate the proportion of farmed salmon represented in the spawning stock of native Atlantic Salmon Salmo salar populations. These surveys take place after the ...
