    • Later at higher latitudes: large-scale variability in seabird breeding timing and synchronicity 

      Burr, Zofia M.; Varpe, Øystein; Anker-Nilssen, Tycho; Erikstad, Kjell E; Descamps, Sébastien; Barrett, Robert T.; Bech, Claus; Christensen-Dalsgaard, Signe; Lorentsen, Svein-Håkon; Moe, Børge; Reiertsen, Tone Kristin; Strøm, Hallvard (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-05-28)
      In seasonal environments, organisms are expected to optimally schedule reproduction within an annual range of environmental conditions. Latitudinal gradients generate a range of seasonality to which we can expect adaptations to have evolved, and can be used to explore drivers of timing strategies across species’ distribution ranges. This study compares the timing of egg hatching in four seabird ...
    • Sedimentary ancient DNA from Lake Skartjørna, Svalbard: Assessing the resilience of arctic flora to Holocene climate change 

      Alsos, Inger Greve; Sjögren, Per Johan E.; Edwards, Mary E.; Landvik, Jon Y.; Gielly, Ludovic; Forwick, Matthias; Coissac, Eric; Brown, Antony G; Jakobsen, Leif Vidar; Merkel, Marie Kristine Føreid; Pedersen, Mikkel Winter (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-11-11)
    • Tønsnes Havn, Tromsø kommune, Troms. Rapport fra de arkeologiske undersøkelsene 2014 

      Nergaard, Ragnhild Holten; Oppvang, Janne; Cerbing, Mikael; Kjellman, Erik; Sommerseth, Ingrid; Niemi, Anja Roth (Research report; Forskningsrapport, 2016)
      I 2014 ble den sørvestlige delen av Skarpeneset undersøkt ved arkeologiske utgravinger. Her ble lokaliteter fra eldre og yngre steinalder og tidlig metalltid undersøkte. Det ble blant annet gravd flere hustufter, ildsteder, knakkeplasser, og aktivitetsområder. Funnene var varierte, og besto av blant annet skiferredskaper, flatehugde gjenstander og asbestkeramikk. Undersøkelsene viser en utstrakt ...

      Aarekol, Lena (Chronicle; Kronikk, 2015-09-23)
    • Past Arctic aliens have passed away, current ones may stay 

      Alsos, Inger Greve; Ware, Christopher; Elven, Reidar (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-07-04)
      Increased human activity and climate change are expected to increase the numbers and impact of alien species in the Arctic, but knowledge of alien species is poor in most Arctic regions. Through field investigations over the last 10 years, and review of alien vascular plant records for the high Arctic Archipelago Svalbard over the past 130 years, we explored long term trends in persistence and ...

      Haugen, Marit S.; Brandth, Berit; Kramvig, Britt (Research report; Forskningsrapport, 2010)
    • Characterization of 14 microsatellite markers for Silene acaulis (Caryophyllaceae) 

      Müller, Eike; Hlavackova, Iva; Svoen, Mildrid Elvik; Alsos, Inger Greve; Eidesen, Pernille Bronken (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-09-08)
      Premise of the study: Fifty candidate microsatellite markers, generated using 454 shotgun sequencing, were tested for the widespread arctic/alpine herb Silene acaulis (Caryophyllaceae). Methods and Results: Fourteen out of 50 markers resulted in polymorphic products with profiles that enabled interpretation. The numbers of alleles per locus ranged from two to six, and the expected heterozygosity ...
    • En sen vikingtids våpengrav med østlige trekk fra Løding, Bodø k. 

      Arntzen, Johan Eilertsen (Research report; Forskningsrapport, 2015-12)
      Som følge av amatørinngrep i ei vikingtids våpengrav på Østre Løding i Bodø kommune gjennomførte Tromsø Museum ei sikringsutgravning i 2014. Undersøkelsene viste at grava var anlagt på et svaberg med ei naturlig bergrenne som gravkammer. Den gravlagte var utstyrt med et våpensett (øks, sverd og spyd), syv perler av glass, rav og glassfluss og hadde med seg ei hesteskoforma ringspenne med østlig ...
    • Biological introduction risks from shipping in a warming Arctic 

      Ware, Christopher; Berge, Jørgen; Jelmert, Anders; Olsen, Steffen M.; Pellisier, Loic; Wisz, Mary S.; Kriticos, Darren J.; Semenov, Georgy; Kwasniewski, Sawomir; Alsos, Inger Greve (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-12-14)
      Several decades of research on invasive marine species have yielded a broad understanding of the nature of species invasion mechanisms and associated threats globally. However, this is not true of the Arctic, a region where ongoing climatic changes may promote species invasion. Here, we evaluated risks associated with non-indigenous propagule loads discharged with ships' ballast water to the high-Arctic ...
    • Reindrift, hushold og kjønn: Sør-Troms på 1700-tallet, i historisk kildemateriale. 

      Storm, Dikka (Journal article; Tidsskriftartikkel; Peer reviewed, 2015)
      Focusing on women’s and men’s participation, this article sheds light on the reindeer herding on the island of Hinnøya and in the southern areas of the county of Troms, Northern Norway, during the 18th and 19th centuries. In this region the Sámi and the Norwegian populations have been living side by side for a long period. In addition to hunting and gathering, the economy of the Sámi population was ...
    • Maskulinitet og trofejakt i Arktis 

      Aarekol, Lena (Journal article; Tidsskriftartikkel; Peer reviewed, 2015)
      From the late 1800s and until the protection of polar bears came into force in 1973, there were regular private hunting expeditions to the Arctic by boat, including several from Tromsø. In this article, I investigate how masculinity is manifested in specific empirical evidence: a trophy hunting expedition with the Sutton family that left from Tromsø in the summer of 1932. Using masculinity as a lens ...
    • Effects of asymmetric nuclear introgression, introgressive mitochondrial sweep, and purifying selection on phylogenetic reconstruction and divergence estimates in the pacific clade of Locustella Warblers 

      Drovetski, Sergei V.; Semenov, Georgy; Red'kin, Yaroslav A.; Fadeev, Igor V.; Koblik, Eugeniy A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-04-07)
      When isolated but reproductively compatible populations expand geographically and meet, simulations predict asymmetric introgression of neutral loci from a local to invading taxon. Genetic introgression may affect phylogenetic reconstruction by obscuring topology and divergence estimates. We combined phylogenetic analysis of sequences from one mtDNA and 12 nuDNA loci with analysis of gene flow ...
    • Reconstruction as trope of cultural display. Rethinking the role of “living exhibitions” 

      Baglo, Cathrine (Journal article; Tidsskriftartikkel; Peer reviewed, 2015)
      During the nineteenth and early twentieth century, a new and particularly widespread type of exhibition practice occurred all over the Western World, namely “living exhibitions”. They were characterized by the display of indigenous and exotic-looking peoples in zoological gardens, circuses, amusement parks, various industrial expositions, and major international expositions where representatives ...
    • Scented grasses in Norway - Identity and uses 

      Alm, Torbjørn (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, ...
    • Birch (Betula, Betulacae) bark horns and similar instruments in Norway. 

      Alm, Torbjørn (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-11-30)
      Wooden horns wrapped in coiled birch bark (Norwegian: lur) have a long history in Norway, dating back at least to the 7th century AD. By the Vikings, they were used for various signalling purposes, e.g. during battles. More recent uses are generally peaceful—to celebrate the opening of fairs, announce bishop visitations etc. In the 19th century, playing such instruments was as a popular past-time ...
    • Plant species introduced by foreigners according to folk tradition in Norway and some other European countries: Xenophobic tales or not? 

      Alm, Torbjørn (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-10-05)
      Background In their quest to understand and interpret nature, people have frequently sought religious or divine origins for plant species and their characteristics. Less often, historical events or persons are involved. This study comprises eleven cases of the latter kind, all claiming that plant species have been introduced by foreigners or at least from foreign lands. Methods Based on literature ...
