Digestive contents and food webs record the advent of dinosaur supremacy
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-11-27)The early radiation of dinosaurs remains a complex and poorly understood evolutionary event<sup>1–4</sup> . Here we use hundreds of fossils with direct evidence of feeding to compare trophic dynamics across five vertebrate assemblages that record this event in the Triassic–Jurassic succession of the Polish Basin (central Europe). Bromalites, fossil digestive products, increase in size and diversity ... -
Insights into early animal evolution from the genome of the xenacoelomorph worm Xenoturbella bocki
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-10-29)The evolutionary origins of Bilateria remain enigmatic. One of the more enduring proposals highlights similarities between a cnidarian-like planula larva and simple acoel-like flatworms. This idea is based in part on the view of the Xenacoelomorpha as an outgroup to all other bilaterians which are themselves designated the Nephrozoa (protostomes and deuterostomes). Genome data can provide important ... -

Drivers of Interspecific Spatial Segregation in Two Closely-Related Seabird Species at a Pan-Atlantic Scale
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-11-11)Aim - Ecologically similar species living in sympatry are expected to segregate to reduce the effects of competition where resources are limiting. Segregation from heterospecifics commonly occurs in space, but it is often unknown whether such segregation has underlying environmental causes. Indeed, species could segregate because of different fundamental environmental requirements (i.e., ‘niche ... -
Holocene summer temperature reconstruction from plant sedaDNA and chironomids from the northern boreal forest
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-10-30)Climate-induced ecotonal shifts are expected to occur in the (sub)arctic and boreal zones in the coming decades. Understanding how these ecosystems have previously responded to climate change can provide greater insight into how ecosystems may develop under existing and future pressures. Here we present a Holocene record from Lake Horntjernet, a lake on the northern edge of the boreal forest in ... -
Dealing with Nordic Colonialism: Agency and Othering in Two Art Projects Invoking Living Ethnographic Displays
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-11-08)In this article we explore two art projects that each, in their own way, thematise Nordic European colonialism and exhibition culture, and the relationship between the two. European Attraction Limited, by the Swedish-Norwegian artist Lars Cuzner and the Sudanese-Norwegian artist Mohamed Ali Fadlabi, was presented in the context of the Bicentenary of the Norwegian Constitution in Oslo in 2014. The ... -
Dynamic home range of the grey-sided vole Craseomys rufocanus: a pilot study

Home ranges have been mapped for some species of voles (subfamily Microtinae) but remain virtually unknown for many species, including the grey-sided vole Craseomys rufocanus. <p>Results A small pilot study was carried out ... -
This Drum Is Not the Devil's Instrument: The Development and Performance of Drum Tunes in Norwegian Folk Music
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-09-18)Trommeslåtter (drum tunes) have played a vital role in Norwegian traditional music for several hundred years. This article examines the development and performance of drum tunes in Norway, with a special focus on the work of Johannes Sundvor in transcribing drum music. We present several examples and analyse tunes from Sundvor’s collection. We also demonstrate how this Norwegian drum tradition ... -
Diversity, toxicity, and distribution of potentially toxic diatoms in Antarctic waters––With description of Pseudo-nitzschia meridionalis sp. nov. and P. glacialis sp. nov.
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-09-12)Diatoms of the genus Pseudo-nitzschia, known for their potential toxicity, are integral to the phytoplankton community of the Southern Ocean, which surrounds Antarctica. Despite their ecological importance, the diversity and toxicity of Pseudo-nitzschia in this region remain underexplored. Globally, these diatoms are notorious for forming harmful algal blooms in temperate and tropical waters, causing ... -

A renaissance of microRNAs as taxonomic and phylogenetic markers in animals
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-06-21)Molecular markers for tracing animal sample origins and compositions are critical for applications such as parasite detection, contamination screening, and sample authentication. Among these, microRNAs have emerged as promising candidates due to their deep conservation, near-hierarchical evolution, and sta bility. I here review the suitability of microRNAs as taxonomic and also phylo genetic ... -
Microbial community composition unaffected by mycorrhizal plant removal in sub-arctic tundra
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-03-11)Vegetation changes in a warming Arctic may affect plant-associated soil microbial communities with possible consequences for the biogeochemical cycling of carbon (C) and nitrogen (N). In a sub-arctic tundra heath, we factorially removed plant species with ecto- and ericoid mycorrhizal associations. After two years, we explored how mycorrhizal type-specific plant removal influences microbial ... -
Extra-pair paternity and sperm length variation in a far northern Great Tit (Parus major) population
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-07-25)Extra-pair paternity is common among socially monogamous bird species and considered an important driver of post-copulatory sexual selection on ejaculate traits including sperm traits. Patterns of extra-pair paternity and sperm size both show substantial variation among populations, yet we know little about the expression of these key reproductive traits at high latitudes. Here we report patterns ... -
