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.

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 ... -

Hagfish genome elucidates vertebrate whole-genome duplication events and their evolutionary consequences
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-01-12)Polyploidy or whole-genome duplication (WGD) is a major event that drastically reshapes genome architecture and is often assumed to be causally associated with organismal innovations and radiations. The 2R hypothesis suggests that two WGD events (1R and 2R) occurred during early vertebrate evolution. However, the timing of the 2R event relative to the divergence of gnathostomes ( jawed vertebrates) ... -
Ancient DNA and osteological analyses of a unique paleo-archive reveal Early Holocene faunal expansion into the Scandinavian Arctic
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-03-29)Paleo-archives are essential for our understanding of species responses to climate warming, yet such archives are extremely rare in the Arctic. Here, we combine morphological analyses and bulk-bone metabarcoding to investigate a unique chronology of bone deposits sealed in the high-latitude Storsteinhola cave system (68°50′ N 16°22′ E) in Norway. This deposit dates to a period of climate warming ...
