    • Range shifts and global warming: ecological responses of Empetrum nigrum L. to experimental warming at its northern (high Arctic) and southern (Atlantic) geographical range margin 

      Buizer, B; Weijers, S; van Bodegom, PM; Alsos, Inger Greve; Eidesen, Pernille Bronken; van Breda, J; de Korte, M; van Rijckevorsel, J; Rozema, J (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      Global change is expected to lead to range shifts of plant species. The ecological mechanisms underpinning these shifts are currently not well understood. Here, we compared ecological responses possibly underlying southern range contraction and northern range expansion of Empetrum nigrum, a key species in northern heathlands, which may be related to global change. We hypothesized a negative ...

      The Digermulen Peninsula in northeastern Finnmark, Arctic Norway, comprises one of the most complete Ediacaran–Cambrian transitions worldwide with a nearly continuous record of micro- and macrofossils from the interval of the diversification of complex life. Here, we report on the provenance and post-depositional alteration of argillaceous mudstones from the Digermulen Peninsula using rare earth ...
    • A Rarely Seen Taxonomic Revision with Immense Value for 41 Years and Counting: Reflections on the 1981 Monograph of Trichonta Winnertz, 1864 (Diptera: Mycetophilidae) by Raymond Gagné, with an Integrative Revision of the Trichonta Vulcani (Dziedzicki, 1889) Species Complex. 

      Kjærandsen, Jostein; Jakovlev, Jevgeni; Polevoi, Alexei; Salmela, Jukka; Kurina, Olavi (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-12-08)
      We celebrate Raymond J. Gagné for his contributions to taxonomy of the Mycetophilidae (Diptera), specifically for his forty-one-years-old monograph of Holarctic Trichonta Winnertz, 1864 that is still the primary source used for species identification in the genus. We briefly reflect on his monograph´s impact and demonstrate by use of recent DNA barcode data extracted from BOLD Systems (BOLD) ...
    • Recent decline in body condition of departing Common Guillemots Uria aalge at Hornøya, North Norway 

      Barrett, Robert T. (Journal article; Tidsskriftartikkel; Peer reviewed, 2010)
      Since 1980, there has been large variation and a recent decline in the mass and body condition of Common Guillemot Uria aalge chicks departing from the nest site in NE Norway. This may be related to deterioration in the feeding conditions off the colony and is alarming considering the critically endangered status of the species in Norway. To measure body condition, earlier studies have caught, weighed ...
    • Reconstructing the invasion history of Heracleum persicum (Apiaceae) into Europe 

      Rijal, Dilli Prasad; Alm, Torbjørn; Jahodová, Šárka; Stenøien, Hans K.; Alsos, Inger Greve (Journal article; Tidsskriftartikkel, 2015-11-06)
      Sparse, incomplete and inappropriate historical records of invasive species often hamper invasive species management interventions. Population genetic analyses of invaders might provide a suitable context for the identification of their source populations and possible introduction routes. Here, we describe the population genetics of Heracleum persicum Desf. ex Fisch and trace its route of introduction ...
    • 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 ...

      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 ...
    • Resident bird species track inter-annual variation in spring phenology better than long-distance migrants in a subalpine habitat 

      Søraker, Jørgen Skavdal; Stokke, Bård Gunnar; Kleven, Oddmund; Moksnes, Arne; Rudolfsen, Geir; Skjærvø, Gine Roll; Vaagland, Henriette; Røskaft, Eivin; Ranke, Peter Sjolte (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-11)
      The ability to track variation in climate is important for species to persist in a given environment. Lack of responses to both long-term changes and inter-annual variation in climate parameters can result in reduced fitness and population decline. Furthermore, migration strategy can influence the ability to track climatic variation due to the potential to use reliable environmental cues. Here, ...
    • Resilient communities? Collapse and recovery of a social-ecological system in Arctic Norway 

      Broderstad, Else Grete; Eythórsson, Einar (Journal article; Tidsskriftartikkel; Peer reviewed, 2014)
      Fisheries-dependent Sami communities in the Norwegian Arctic face major challenges adapting and responding to socialecological changes. On a local scale, communities and households continually adapt and respond to interacting changes in natural conditions and governance frameworks. Degradation of the marine environment and decline in coastal settlements can move socialecological systems beyond ...
    • Rethinking Sami Agency during Living Exhibitions: From the Age of Empire to the Postwar World 

      Baglo, Cathrine (Chapter; Bokkapittel, 2014)
      In the fall of 2008, the state-owned Norwegian Broadcasting Company (NRK), a noncommercial and highly-regarded channel, presented its new Saturday night show: „The Great Travel‟. The plot was simple. Three Norwegian families were sent into the „bush‟ to live for three weeks with three different indigenous groups around the World. One of the groups, the Waorani in the Ecuadorian Amazon, appeared more ...

    • Rocetelion humerale (Zetterstedt, 1850) (Diptera, Keroplatidae) rediscovered in Norway after more than 100 years, with description of the larva and its habitat. 

      Kjærandsen, Jostein (Journal article; Tidsskriftartikkel; Peer reviewed, 2022)
      The large and conspicuous keroplatid species Rocetelion humerale (Zetterstedt, 1850) was previously documented with a single record from Norway only, a more than one hundred-year-old record of a male from Erfjord in Rogaland County, published in 1914, for which the voucher specimen has been searched for in vain in museum collections. In the summer of 2020, a new record of an adult male was ...
    • The role of sea ice for vascular plant dispersal in the Arctic 

      Alsos, Inger Greve; Ehrich, Dorothee; Seidenkrantz, Marit-Solveig; Bennike, Ole; Kirchhefer, Andreas; Geirsdottir, Aslaug (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-09)
      Sea ice has been suggested to be an important factor for dispersal of vascular plants in the Arctic. To assess its role for postglacial colonization in the North Atlantic region, we compiled data on the first Late Glacial to Holocene occurrence of vascular plant species in East Greenland, Iceland, the Faroe Islands and Svalbard. For each record, we reconstructed likely past dispersal events ...

      Nyyssönen, Jukka; Keskitalo, Pigga Päivi Kristiina; Linkola, Inker-Anni; Paksuniemi, Merja; Turunen, Tuija; McIntosh, Leonie (Journal article; Tidsskriftartikkel; Peer reviewed, 2016)
    • Sameleire i Tromsø som turistmål, fotomotiv og møteplass 

      Baglo, Cathrine (Journal article; Tidsskriftartikkel, 2015)
      Sameleiren i Tromsdalen var lenge det mest besøkte turistmålet i Tromsø. Betydningen Tromsdalen og andre sameleire fikk som fotomotiv og møteplass i siste del av 1800-tallet, og hvordan dette skulle bidra til å bygge opp om interessen for reindriftssamenes levesett, er mindre kjent. Et resultat av den økte interessen var at sameleire ble gjenskapt i kommersiell og folkeopplysende øyemed, både nasjonalt ...
