    • Failure of two consecutive annual treatments with ivermectin to eradicate the reindeer parasites (Hypoderma tarandi, Cephenemyia trompe and Linguatula arctica) from an island in northern Norway. 

      Nilssen, Arne C.; Hemmingsen, Willy; Haugerud, Rolf E. (Journal article; Tidsskriftartikkel; Peer reviewed, 2002)
      The highly efficient endectocide ivermectin is used to reduce the burden of parasites in many semidomestic reindeer herds in northern Fennoscandia. In the autumn of 1995 and 1996 all reindeer on the island of Silda (42 km2) were treated with ivermectin in an attempt to eradicate the warble fly (Hypoderma (=Oedemagena) tarandi (L.)), the nose bot fly (Cephenemyia trompe (Modeer)) (Diptera: Oestridae) ...
    • Fear and Fascination: Anti-Landscapes between Material Resistance and Material Transcendence 

      Bigell, Werner (Chapter; Bokkapittel, 2014-11-01)
      This article examines the mechanisms that turn landscapes into anti-landscapes: projection, material interference, and ideological contradiction. Landscape and anti-landscape are dialectical twins; whereas landscape affirms cultural and aesthetic values, anti-landscape negates them through material resistance. This negation creates a sense of material transcendence, the aesthetic appeal through ...
    • Fern rhizomes as fodder in Norway 

      Alm, Torbjørn (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-09-06)
      Background: Although ferns are often known under collective names in Norway, e.g. blom, a substantial number of vernacular names for individual fern species are known, in particular for useful or poisonous taxa. In the past, the rhizomes (Norwegian: moldfôr) of selected species were collected for fodder. Only scattered records of such use are available from southern Norway, and the tradition’s ...
    • Fiskerbonden i Nord-Troms 1300-1700 : belyst ved tuftegravninger 

      Simonsen, Povl (Research report; Forskningsrapport, 1980)
    • Fjern undervisning? 

      Fliflet, Andreas (Journal article; Tidsskriftartikkel, 2013)
      Fra fortidens kassett i polstret konvolutt til dagens online-kurs med tusenvis av elever og jazzlærer i USA; fjernundervisning i musikk er kommet for å bli.
    • FlexiNet - QoS Investigation 

      Hanssen, Øyvind (Research report; Forskningsrapport, 1997)
      In this report we investigate what are the main concepts and issues in the support of Quality of Service, focusing at open distributed computing and middleware platforms. We study how these issues are being addressed in research on QoS support related to middleware. QoS is about non-functional properties in general, but research has been centred around communication protocols and multimedia. The ...
    • Fra steinalder til jernalder på Skålbunes : RV 17-prosjektet på Tverlandet, Bodø kommune, Nordland 

      Arntzen, Johan Eilertsen; Olsen, Morten; Grydeland, Sven Erik; Hole, Johan Terje (Research report; Forskningsrapport, 2008-05)
      RV 17 – prosjektet på Tverlandet har vært gjennomført av Tromsø museum, Universitetsmuseet – Seksjon for kulturvitenskap. Forberedelser, de arkeologiske undersøkelsene og etterarbeidet har tatt rundt to år, hvor utgravningene foregikk somrene 2006 og 2007. Det ble funnet to større boplasser fra steinalder. I tid ligger disse i siste del av boreal og første del av atlantisk tid. Tidligere er det ...

    • 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 ...
    • Gamnes, Sør-Varanger k. Forvaltningsutgravning av en lokalitet fra eldre steinalder, id. 158956 og en gammetuft id. 158949 

      Oppvang, Janne; Kjellman, Erik; Niemi, Anja Roth; Lind, Keth Elisabeth (Research report; Forskningsrapport, 2017)
      I løpet av 5 uker i august-september 2015 ble det undersøkt en registrert gammetuft, id.158949 og en åpen steinalderboplass,id.158956 på Gamnes i Sør-Varanger. Gammetufta viste seg å være et ishus/laksegamme fra nyere tid. Steinalderboplassen er en åpen sadellokalitet med aktivitetsområder og materiale som knyttes til første del av eldre steinalder. Dateringer fra lokaliteten vitner om en bruk også ...
    • The genetic basis and enigmatic origin of melanic polymorphism in the pomarine skua (Stercorarius pomarinus) 

      Janssen, Kirstin; Mundy, Nicholas I. (Journal article; Tidsskriftartikkel, 2017-12-06)
      A key outstanding issue in adaptive evolution is the relationship between the genetics of intraspecific polymorphism and interspecific evolution. Here, we show that the pale/dark ventral plumage polymorphism that occurs in both the pomarine skua (Stercorarius pomarinus) and Arctic skua (S. parasiticus) is the result of convergent evolution at the same locus (MC1R), involving some of the same amino ...
    • A genetic fingerprint of Amphipoda from Icelandic waters – the baseline for further biodiversity and biogeography studies 

      Jażdżewska, Anna M.; Corbari, Laure; Driskell, Amy; Frutos, Inmaculada; Havermans, Charlotte; Hendrycks, Ed; Hughes, Lauren E.; Lörz, Anne-Nina; Stransky, Bente; Tandberg, Anne Helene S.; Vader, Wim; Brix, Saskia (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-01-23)
      Amphipods constitute an abundant part of Icelandic deep-sea zoobenthos yet knowledge of the diversity of this fauna, particularly at the molecular level, is scarce. The present work aims to use molecular methods to investigate genetic variation of the Amphipoda sampled during two IceAGE collecting expeditions. The mitochondrial cytochrome oxidase subunit 1 (COI) of 167 individuals originally assigned ...

      Myhr, Anne Ingeborg; Traavik, Terje (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
    • Geographic mode of speciation in a mountain specialist avian family endemic to the Palearctic 

      Drovetski, Sergei V.; Semenov, Georgy; Drovetskaya, Sofya S.; Fadeev, Igor V.; Red'kin, Yaroslav A.; Voelker, Gary (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      Mountains host greater avian diversity than lowlands at the same latitude due to their greater diversity of habitats stratified along an elevation gradient. Here we test whether this greater ecological heterogeneity promotes sympatric speciation. We selected accentors (Prunellidae), an avian family associated with mountains of the Palearctic, as a model system. Accentors differ in their habitat/elevation ...
    • Germinating seeds or bulbils in 87 of 113 tested Arctic species indicate potential for ex situ seed bank storage 

      Alsos, Inger Greve; Müller, Eike; Eidesen, Pernille Bronken (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      Arctic plant species are expected to lose range due to climate change. One approach to preserve the genetic and species diversity for the future is to store propagules in seed vaults. However, germinability of seeds is assumed to be low for Arctic species. We evaluated ex situ storage potential of 113 of the 161 native angiosperms of Svalbard by studying seed ripening and germination. Seeds or bulbils ...
    • Giant invasive Heracleum persicum: Friend or foe of plant diversity? 

      Rijal, Dilli Prasad; Alm, Torbjørn; Nilsen, Lennart; Alsos, Inger Greve (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-05-30)
      The impact of invasion on diversity varies widely and remains elusive. Despite the con- siderable attempts to understand mechanisms of biological invasion, it is largely un- known whether some communities’ characteristics promote biological invasion, or whether some inherent characteristics of invaders enable them to ...

      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, ...
