Changes in Onset of Vegetation Growth on Svalbard, 2000–2020
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-12-15)The global temperature is increasing, and this is affecting the vegetation phenology in many parts of the world. The most prominent changes occur at northern latitudes such as our study area, which is Svalbard, located between 76300N and 80500N. A cloud-free time series of MODIS-NDVI data was processed. The dataset was interpolated to daily data during the 2000–2020 period with a 231.65 m pixel ... -

(Research report; Forskningsrapport, 2019)I 2012-2013 ble et chertbrudd fra steinalderen undersøkt utenfor Alta i Finnmark. Undersøkelsen omfattet 1000 m2 av steinbruddet, og 3500 m2 av bosetingsområdene som lå like ved. I tillegg til utgravning ble det gjort eksperimenter med utvinning av chert i bruddet. Resultatene viser at bruddet ble brukt allerede 8400 f.Kr., og at fyrsetting var den viktigste metoden for å bryte chert fra berget. ... -
Choices and omissions of knowledge and social impact in Finnish committee reports on Sámi policies
(Chapter; Bokkapittel, 2021)In Finland, the involvement of scholars in politics has been particularly strong: scholars and professors have occupied positions in high politics, produced research that was meant as a direct comment on topical political debates, and been active in civil society (Häggman, 2012). In addition to advising high politics and acting in civil society, the Finnish committee institution, a third emerging ... -
The Church, Pietist Mission and The Sámi. - An Account of a Northern Norwegian Mission District in the Early Eighteenth Century.
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017)The indigenous religion of the Sámi population came under strong pressure through the Pietist mission effort, which occurred during the first decades of the 18th century in Denmark-Norway. This study focuses on the complex religious situation in the areas of the Northern Norwegian counties of Nordland and Troms. The study uses a spatial approach to map the positions of the different institutions ... -
Circumpolar Arctic vegetation: a hierarchic review and roadmap toward an internationally consistent approach to survey, archive and classify tundra plot data
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-05-10)Satellite-derived remote-sensing products are providing a modern circumpolar perspective of Arctic vegetation and its changes, but this new view is dependent on a long heritage of ground-based observations in the Arctic. Several products of the Conservation of Arctic Flora and Fauna are key to our current understanding.Wereview aspects of the PanArctic Flora, the Circumpolar Arctic Vegetation ... -
Circumpolar dynamics of a marine top-predator track ocean warming rates.
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-04-07)Global warming is a nonlinear process, and temperature may increase in a stepwise manner. Periods of abrupt warming can trigger persistent changes in the state of ecosystems, also called regime shifts. The responses of organisms to abrupt warming and associated regime shifts can be unlike responses to periods of slow or moderate change. Understanding of nonlinearity in the biological responses to ... -
Climate change, non-indigenous species and shipping: assessing the risk of species introduction to a high-Arctic archipelago
(Journal article; Tidsskriftartikkel; Peer reviewed, 2013)Aim: Anticipated changes in the global ocean climate will affect the vulnerability of marine ecosystems to the negative effects of non-indigenous species (NIS). In the Arctic, there is a need to better characterize present and future marine biological introduction patterns and processes. We use a vector-based assessment to estimate changes in the vulnerability of a high-Arctic archipelago to marine ... -
Climate fluctuations and differential survival of bridled and non-bridled Common Guillemots Uria aalge
(Journal article; Tidsskriftartikkel; Peer reviewed, 2012-06-22)Climate fluctuations and its effects on ecological processes are evident in most areas worldwide but whether such climatic effects are induced phenotypic plasticity or whether animals adapt to the new environment through micro‐evolutionary processes is poorly known. In this study we have analyzed long‐term data (22 years) on the relationship between climatic fluctuations and the adult survival of ... -
Climate-Driven Ichthyoplankton Drift Model Predicts Growth of Top Predator Young
(Journal article; Tidsskriftartikkel; Peer reviewed, 2013-11-12)Climate variability influences seabird population dynamics in several ways including access to prey near colonies during the critical chick-rearing period. This study addresses breeding success in a Barents Sea colony of common guillemots Uria aalge where trophic conditions vary according to changes in the northward transport of warm Atlantic Water. A drift model was used to simulate interannual ... -
Clitellate worms (Annelida) in late-glacial and Holocene sedimentary DNA records from the Polar Urals and northern Norway
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-26)While there are extensive macro‐ and microfossil records of a range of plants and animals from the Quaternary, earthworms and their close relatives amongst annelids are not preserved as fossils and therefore the knowledge of their past distributions is limited. This lack of fossils means that clitellate worms (Annelida) are currently underused in palaeoecological research, even though they can provide ... -
Comprehensive coverage of human last meal components revealed by a forensic DNA metabarcoding approach
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-23)Stomach content analyses are a valuable tool in human forensic science to interpret perimortem events. While the identifcation of food components of plant and animal origin has traditionally been conducted by macro- and microscopical approaches in case of incomplete digestion, molecular methods provide the potential to increase sensitivity and taxonomic resolution. In particular, DNA metabarcoding ... -
A comprehensive framework for analysis of microRNA sequencing data in metastatic colorectal cancer
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-14)Although microRNAs (miRNAs) contribute to all hallmarks of cancer, miRNA dysregulation in metastasis remains poorly understood. The aim of this work was to reliably identify miRNAs associated with metastatic progression of colorectal cancer (CRC) using novel and previously published nextgeneration sequencing (NGS) datasets generated from 268 samples of primary (pCRC) and metastatic CRC (mCRC; ... -
Considerations and consequences of allowing DNA sequence data as types of fungal taxa
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-24)Nomenclatural type definitions are one of the most important concepts in biological nomenclature. Being physical objects that can be re-studied by other researchers, types permanently link taxonomy (an artificial agreement to classify biological diversity) with nomenclature (an artificial agreement to name biological diversity). Two proposals to amend the International Code of Nomenclature for algae, ... -
A cosmopolitan, Sami-friendly scholar? Väinö Tanner on the best way to treat the Sami
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016)The topic of this article is Väinö Tanner’s views on Sami policies, which are searched from numerous contexts, including his personal career and Nordic Sami policies. Also the discur-sive resources, which he re-produced, are charted. Of the contemporaneous Sami policies, he ad-vocated the Swedish variant, which suited better his agendas in his scholarly production on the Skolt Sami. The origin of ... -
