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 ... -

Alt eller ingenting: Annerledesgjøren og agens i to (post)koloniale kunstprosjekter
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-22)Artikkelen tar utgangspunkt i to kunstprosjekter som på ulike måter tematiserer europeisk utstillingskultur og nordisk kolonialisme i fortid og nåtid; «European Attraction Limited» av Lars Cuzner og Cassius Fadlabi (2011–14) og Joar Nangos «European Everything» (2017). Prosjektene diskuteres i lys av en historisk utstillingspraksis som prosjektene påkaller på en direkte eller indirekte måte, nemlig ... -
Narratives of Sámi School History in Finland: The Histories of Assimilation Made Visible
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018)This article analyses narratives that have been produced about the Sámi school experience in Finland. The sources consist of studies in Sámi school history and history of education in Finland, as well as in pedagogical studies made since the 1980s, comparing the narratives found in each case. The narrative of assimilation dominates the field for good, historically verifiable reasons. This genre of ... -
Sámi natural resource exploitation in a markebygd and its significance today?
(Journal article; Tidsskriftartikkel; Peer reviewed, 1993)<i>Introduction</i>: In my investigation (Storm 1990) of the markebygd of Rásmirvuovdi/Gressmyrskogen on the island of Sážžá/Senja in the province of Romssa/Troms, I have reconstructed the settlement process from 1700 to 1900 AD. The focus was on the practice of Sámi resource exploitation – which resources and resource areas were used, and how the land was exploited – and what kind of Sámi settlements ... -

Global phenological insensitivity to shifting ocean temperatures among seabirds
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-04-02)Reproductive timing in many taxa plays a key role in determining breeding productivity, and is often sensitive to climatic conditions. Current climate change may alter the timing of breeding at different rates across trophic levels, potentially resulting in temporal mismatch between the resource requirements of predators and their prey. This is of particular concern for higher-trophic-level organisms, ... -
