    • 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 ...
    • Rapid laminated clastic alluviation associated with increased Little Ice Age flooding co-driven by climate variability and historic land-use in the middle Severn catchment, UK 

      Pears, Ben; Brown, Antony Gavin; Toms, Phillip S; Wood, Jamie; Pennington, Benjamin T; Jones, Richard (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-06)
      The analysis of exceptionally well-preserved visible clastic laminations in deep alluvial sediments at Kempsey, Worcestershire (UK), allows a new highresolution analysis of late-Holocene flood-history in the largest UK catchment, as well as local human response. At the sample site over 4.5m of sandy-silt overbank-alluvium accumulated on the floodplain and optically stimulated luminescence (OSL) ...

      Aspaas, Per Pippin (Journal article; Tidsskriftartikkel, 2015)
    • Rare earth elements and neodymium and strontium isotopic constraints on provenance switch and post-depositional alteration of fossiliferous Ediacaran and lowermost Cambrian strata from Arctic Norway. 

      Meinhold, Guido; Willbold, Matthias; Karius, Volker; Jensen, Sören; Agić, Heda; Ebbestad, Jan Ove R.; Palacios, Teodoro; Högström, Anette; Høyberget, Magne; Taylor, Wendy L. (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-16)
      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 ...
    • REFRESH RATE: ON THE AGE OF FLUX AND AFTER AFFECT 

      Kovalevskij, Vsevolod (Master thesis; Mastergradsoppgave, 2017-11-28)
      This essay is about constantly refreshing hyperobjective human conditions - the after affects of posthumanist thinking in the age of constant flux. I use the term constant flux to describe the intensity of change in the technological world where one feels somewhat dysfunctional or like a misplaced object, who can’t process all of the incoming data. This is an essay about one day as a hyperobject ...

    • Research Funding is Critical to Societally Relevant Research 

      Benneworth, Paul; Maxwell, Kate (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-13)
      There has been increasing concern recently in ensuring that public funding for science and innovation creates truly public benefits. This has emerged at a time of an uneasy feeling emerging in society that it is private corporations and patent holders that reap the rewards, particularly in new drugs which may be generally unaffordable despite being ‘discovered’ by public funding (Gronde et ...
    • 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 ...

      Aarekol, Lena (Chapter; Bokkapittel, 2018)
      14. desember 1911 ble Sydpolen erobret! Da Roald Amundsen og hans mannskap på fire nådde klodens sydligste punkt som de aller første, var det en verdensbegivenhet. <p> <p>Nordmenns beundring for vågemot, styrke og overlevelsesevne gjorde denne ekspedisjonen til en nasjonal stolthet, og den ble viktig for norsk identitetsbygging (Fulsås 2004, 222). Etter at Fridtjof Nansen hadde krysset Grønland ...

    • 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 ...
