"Kle av serken og dans spille naken". Betydninga av kjønn i tradisjonsmusikken.
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03-07)
This article attempts to investigate how Norwegian traditional music is gendered. There have been few such investigations in the past. Some songs are work songs and function as a tool to lighten the work itself. Each song is created for either men's work, or women's. Other songs describe the actual conditions for men or women. There exist, for example, some songs which illustrate how women had to ...
Scented grasses in Norway - Identity and uses
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-12-23)
Background: Some grass species are richer in coumarin and thus more sweetly scented than others. These have
been eagerly sought after in parts of Norway, but the tradition has been weakly documented, both in terms of the
species collected, their vernacular names, and uses.
<p>Methods: Based on literature data and a substantial body of information collected during my own ethnobotanical
field work, ...
Minimizing polymerase biases in metabarcoding
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-24)
DNA metabarcoding is an increasingly popular method to characterize and quantify biodiversity in environmental samples. Metabarcoding approaches simultaneously amplify a short, variable genomic region, or “barcode,” from a broad taxonomic group via the polymerase chain reaction (PCR), using universal primers that anneal to flanking conserved regions. Results of these experiments are reported as ...
Natural selection shaped the rise and fall of passenger pigeon genomic diversity
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-11-17)
The extinct passenger pigeon was once the most abundant bird in North America, and possibly the world. Although theory predicts that large populations will be more genetically diverse, passenger pigeon genetic diversity was surprisingly low. To investigate this disconnect, we analyzed 41 mitochondrial and 4 nuclear genomes from passenger pigeons and 2 genomes from band-tailed pigeons, which are ...
Population genomics of Mesolithic Scandinavia: Investigating early postglacial migration routes and high-latitude adaptation
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-01-09)
Scandinavia was one of the last geographic areas in Europe to become habitable for humans after the Last Glacial Maximum (LGM). However, the routes and genetic composition of these postglacial migrants remain unclear. We sequenced the genomes, up to 57× coverage, of seven hunter-gatherers excavated across Scandinavia and dated from 9,500–6,000 years before present (BP). Surprisingly, among the ...
The lichen Allocetraria madreporiformis in high-arctic steppes on Svalbard: a result of out-of-Tibet migration?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-01-29)
<i>Allocetraria madreporiformis</i> is a small, finger-like, fruticose lichen with isolated occurrences in the inner fiord section of the long, straight fiord Wijdefjorden in Svalbard. Several new localities are added and mapped here, and we show that the species is confined to exclusive high-arctic steppe habitats on finetextured, moderately alkaline soil, exposed to wind erosion and aeolian transport ...
Scratch circles from the Ediacaran and Cambrian of Arctic Norway and the Republic of South Africa, with a review of scratch circle ocurrences
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-07-13)
Scratch circles - bedding plane parallel sedimentary structures formed by the passive rotation of a tethered organism into the surrounding sediment - are relatively rare in the geological record. Here new occurrences of scratch circles are described from the Ediacaran-Cambrian Stáhpogieddi Formation, Digermulen Peninsula, Arctic Norway, and from the Ediacaran Nudaus and Urusis formations, Nama Group, ...
The taxonomic status of two species of predaceous midges in the genera Bezzia and Palpomyia described by STÆGER (1839) in the genus Ceratopogon (Diptera: Ceratopogonidae: Palpomyiini)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-12-28)
Lectotypes are designated for the predaceous midges, <i>Ceratopogon circumdatus</i> Stæger, 1839, and <i<Ceratopogon binotatus</i> Stæger, 1839 housed in the Copenhagen Zoological Museum, Denmark, and both species are redescribed and photographed. <i>Ceratopogon circumdatus</i> is removed from synonymy with <i>Bezzia solstitialis</i> (Winnertz, 1852) and recognized as a new synonym of <i>Bezzia ...
Bryophytes facilitate outcrossing of Mitella by functioning as larval food for pollinating fungus gnats
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-06-11)
The dependence of long-distance migration to North Norway on environmental conditions in the wintering area and en route
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017)
The onset of bird migration may be under partial endogenous control whereas the timing of movement is flexible with weather and conditions faced by the moving birds being the ultimate cause of variability of arrival dates. This study shows that the early arrival dates of two of three long-distance passerine spring migrants (Willow Warblers Phylloscopus trochilus and Chiffchaffs P. collybita) in North ...
