Past and future effects of climate on the metapopulation dynamics of a Northeast Atlantic seabird across two centuries
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-12-31)Forecasting population responses to rapidly changing marine ecosystems requires mechanistic models integrating complex demographic processes, fitted to long time series, across large spatial scales. We used a Bayesian metapopulation model fit to colony census data and climatic covariates spanning 1900–2100 for all Northeast Atlantic colonies of an exemplar seabird, the Northern gannet (Morus bassanus) ... -
Norske navn på alle karplantefamilier og -ordener
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024)Over time, Norwegian vernacular names have been coined for all vascular plant species, genera, families and orders represented in Norway. Imported, economically important species (used as food, medicine etc.) have also frequently acquired Norwegian names. This still leaves numerous exotic plant families and plant orders without a Norwegian name, albeit sometimes requested e.g. by translators. ... -

Refining Holocene sea-level variations for the Lofoten and Vesterålen archipelagos, northern Norway: implications for prehistoric human–environment interactions
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-03-04)The Lofoten and Vesterålen archipelagos are located off the outer coast of northern Norway far from the center of the former Fennoscandian Ice Sheet and near the continental shelf edge. Existing relative sea‐level (RSL) data indicate a pronounced mid‐Holocene transgression and interesting connections with the region's prehistoric human settlement history. Here we present seven new sea‐level index ... -
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 ... -

Argumentet er at en økobevisst holdning kommer til uttrykk i kunsten og i den omsorgspolitikken og fellesskapsfølelsen som ligger grunn for forbundet. ... -
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 ... -

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 ...
