  • Amphipods and sea anemones, an update 

    Vader, Wim; Tandberg, Anne Helene Solberg (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-02)
    We present an updated survey of the Amphipoda that live in association with sea anemones. These amphipods can be divided into four groups: 1) symbiotic amphipods using sea anemones mainly for protection, but feeding largely independently; 2) amphipods feeding on sea anemones, but not permanently associated; 3) symbiotic amphipods living permanently among the tentacles of the sea anemones; and 4) ...
  • Ti momenter til en (g)lokal kunstkritikk 

    Stien, Hanne Hammer (Journal article; Tidsskriftartikkel, 2020-11-27)
    «Ti momenter til en (g)lokal kunstkritikk» er et forsøk på å gjentenke Dag Solhjells «Ti teser om kunstkritikk i et regionalt perspektiv», publisert på ArtScene Trondheim i 2009. De ti momentene er basert på kunsthistoriker Ruth B. Phillips argumentasjon i artikkelen «Taking the local seriously», publisert i World Art i 2014, og forskning gjort i forbindelse med arbeidet med boken Kunst som deling, ...
  • Onisimus turgidus (Sars, 1879) (Amphipoda, Uristidae), an overlooked amphipod from sea anemones in Northern Norway 

    Vader, Wim; Johnsen, Jan Roger; Tandberg, Anne Helene S. (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-18)
    Two Norwegian uristid amphipods, obligate associates of sea anemones, have for a long time been confused sub nomine <i>Onisimus normani</i> Sars, 1890. In reality this species only occurs in south Norway, while the north-Norwegian material belongs to <i>O. turgidus</i> (Sars, 1879), described from the Barents Sea and for a long time forgotten. This paper fully illustrates both species, gives a key, ...
  • The lichen Allocetraria madreporiformis in high-arctic steppes on Svalbard: a result of out-of-Tibet migration? 

    Elvebakk, Arve; Bjerke, Jarle W.; Nilsen, Lennart (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 ...
  • Genomic Evidence of Widespread Admixture from Polar Bears into Brown Bears during the Last Ice Age 

    Cahill, James A.; Heintzman, Peter D.; Harris, Kelley; Teasdale, Matthew D.; Kapp, Joshua D.; Soares, Andre, E. R.; Stirling, Ian; Bradley, Daniel; Edwards, Ceiridwen J.; Graim, Kiley; Kisleika, Aliaksandr A.; Malev, Alexander V.; Monaghan, Nigel; Green, Richard E.; Shapiro, Beth (Journal article; Tidsskriftartikkel; Preprint; Manuskript, 2018-02-20)
    Recent genomic analyses have provided substantial evidence for past periods of gene flow from polar bears (<i>Ursus maritimus</i>) into Alaskan brown bears (<i>Ursus arctos</i>), with some analyses suggesting a link between climate change and genomic introgression. However, because it has mainly been possible to sample bears from the present day, the timing, frequency, and evolutionary significance ...
  • Sápmi100? Saamelaishistorian vastanarratiivejä Suomi100-tapahtumassa Sajoksessa 

    Nyyssönen, Jukka; Keskitalo, Pigga Päivi Kristiina; Kinnunen, Tiina (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-19)

  • Hr. Kaptein Jacobsen og hans arbeid for Bergens national-ethnografiske forening 

    Baglo, Cathrine (Journal article; Tidsskriftartikkel, 2017)
    I mars 1892 ble Bergens national-ethnografiske forening dannet med formål om å opprette et norsk folkemuseum i byen, enten som egen institusjon eller tilknyttet Bergens Museum. Museet hadde da en mindre samling norske "bondegjenstande". Nå ønsket man å sette i gang et større samlingsarbeid, med vekt på Vestlandet. Allerede fra starten var foreningen tydelig på hvem de ønsket skulle utføre arbeidet, ...
  • New information on the Ediacaran-Cambrian transition in the Vestertana Group, Finnmark, northern Norway, from trace fossils and organic-walled microfossils 

    Högström, Anette; Jensen, Sören; Palacios, Teodoro; Ebbestad, Jan Ove R. (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
    The Vestertana Group on the Digermul Peninsula, Finnmark, northern Norway, presents one of the few, potentially continuous Ediacaran– Cambrian sections in Scandinavia. Trace fossils provide the main age constraint, with the boundary traditionally placed at the base of the Breidvika Formation. Here, we provide trace-fossil evidence to show that this boundary is at least as low as the third cycle of ...
  • Miljø-DNA: Tar pulsen på naturen 

    Mellegård, Hilde (Journal article; Tidsskriftartikkel; Peer reviewed, 2019)
    DNA i vannprøver og jordprøver kan gi verdifull informasjon om hvilke organismer som er til stede i økosystemene i dag, og hvordan livet har utviklet seg over tid.
  • Paradulichia spinifera gurjanova, 1946 (Amphipoda, dulichiidae), a valid species? 

    Johansen, Per-Otto; Vader, Wim (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-11)
    Examination of Paradulichia-material collected from the Barents Sea during the Mareano cruises indicated that there are clear morphological differences between Paradulichia typica Boeck, 1871 from the Hardangerfjord, W. Norway and Paradulichia spinifera Gurjanova, 1946 from the Arctic. Based on our material and the original descriptions, these differences are the acute ventral parts of the body ...
  • Clitellate worms (Annelida) in late-glacial and Holocene sedimentary DNA records from the Polar Urals and northern Norway 

    Lammers, Youri; Clarke, Charlotte; Erséus, Christer; Brown, Antony Gavin; Edwards, Mary Elizabeth; Gielly, Ludovic; Haflidason, Haflidi; Mangerud, Jan; Rota, E; Svendsen, John-Inge; Alsos, Inger Greve (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 ...
  • Evenskjer Syd, Skånland k. Dokumentasjon av dyrkingslag fra Førromersk Jernalder og Vikingtid 

    Sjøgren, Per Johan E; Oppvang, Janne; Kjellman, Erik; Kirchhefer, Andreas; Lind, Keth Elisabeth (Research report; Forskningsrapport, 2018)
    De arkeologiske undersøkelsene fant sted i slutten av mai og varte i to dager. Det ble sjaktet maskinelt for å få fram profiler av dyrkningslagene. To arkeologer og en gravemaskinfører åpnet sjaktene. Paleobotaniker var én dag i felt og stod for prøveuttakning. I profilen identifiseres tre dyrkingslager. Et ble datert til førromersk jernalder, 400–150 f.Kr., et til vikingtida / tidlig middelalder ...

    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, ...
  • Prevention of microbial species introductions to the arctic: The efficacy of footwear disinfection measures on cruise ships 

    Rumpf, Sabine Bettina; Alsos, Inger Greve; Ware, Christopher (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03-06)
    Biosecurity measures are commonly used to prevent the introduction of non-native species to natural environments globally, yet the efficacy of practices is rarely tested under operational conditions. A voluntary biosecurity measure was trialled in the Norwegian high Arctic following concern that non-native species might be transferred to the region on the footwear of travellers. Passengers aboard ...
  • Gammarid amphipods (Crustacea) in Norway, with a key to the species 

    Vader, Wim; Tandberg, Anne Helene Solberg (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-02-28)
    Thirteen species in the amphipod family Gammaridae have been reported from Norway. This paper gives a survey of the distribution and habitat of all 13 species of the family Gammaridae occurring or expected to occur in Norwegian waters: both marine, brackish and fresh, including Svalbard, in addition to four species found in close neighbouring waters. It also provides a short history of the study of ...
  • Vuolmmašjohka i Porsanger. Undersøkelse av tidlig-mesolittisk boplass og samiske kulturminner. Porsanger k., Finnmark f. 

    Oppvang, Janne; Kjellman, Erik (Research report; Forskningsrapport, 2019)
    I 2017 undersøkte Tromsø Museum en boplass fra eldre steinalder, ett árran fra middelalder og skyteskjul antatt å være samiske, men som viste seg å være av moderne karakter. Boplassen fra steinalder besto av ulike funnkonsentrasjoner og kunne dateres til perioden 8500-8200 f. Kr. Gjenstandsmaterialet var innholdsrikt med kjerner, tangespisser, eneggete spisser, mikrolitter og veldokumentert ...
  • Chertbruddet i Melsvik. Undersøkelse av chertbrudd, utvinningsteknologi og bosetningsspor fra tidlig eldre steinalder i Melsvik, Alta k., Finnmark f. 

    Niemi, Anja Roth; Cerbing, Mikael; Nergaard, Ragnhild Holten; Oppvang, Janne; Storemyr, Per (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. ...
  • Prospects and challenges of environmental DNA (eDNA) monitoring in freshwater ponds 

    Harper, Lynsey R.; Buxton, Andrew S.; Rees, Helen C.; Bruce, Kat; Brys, Rein; Halfmaerten, David; Read, Daniel S.; Watson, Hayley V.; Sayer, Carl D.; Jones, Elanor P.; Priestley, Victoria; Mächler, Elvira; Múrria, Cesc; Garcès-Pastor, Sandra; Medupin, Cecilia; Burgess, Katherine; Benson, Gillian; Boonham, Neil; Griffiths, Richard A.; Handley, Lori Lawson; Hänfling, Bernd (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-03)
    Environmental DNA (eDNA) analysis is a rapid, non-invasive, cost-efficient biodiversity monitoring tool with enormous potential to inform aquatic conservation and management. Development is ongoing, with strong commercial interest, and new uses are continually being discovered. General applications of eDNA and guidelines for best practice in freshwater systems have been established, but ...
  • Holocene vegetation change in northernmost Fennoscandia and the impact on prehistoric foragers 12 000–2000 cal. a BP – A review 

    Sjøgren, Per Johan E; Damm, Charlotte Brysting (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-14)
    While single pollen records are widely used in reconstructing the environment for nearby prehistoric settlements, they are less helpful when addressing large‐scale issues of variation in human settlement patterns. In order to assess the impact of vegetation change on regional prehistoric settlement and subsistence patterns in an ecotone sensitive area, we inferred the general change in main vegetation ...
  • Scratch circles from the Ediacaran and Cambrian of Arctic Norway and the Republic of South Africa, with a review of scratch circle ocurrences 

    Jensen, Sören; Högström, Anette; Almond, John E.; Taylor, Wendy L.; Meinhold, Guido; Høyberget, Magne; Ebbestad, Jan Ove R.; Agic, Heda; Palacios, Teodoro (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, ...
