      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 ...

    • 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 ...

      Keogan, Katharine; Daunt, Francis; Wanless, Sarah; Phillips, Richard A.; Walling, Craig A.; Agnew, Philippa; Ainley, David G.; Anker-Nilssen, Tycho; Ballard, Grant; Barrett, Robert T; Barton, Kerry J.; Bech, Claus; Becker, Peter; Berglund, Per-Arvid; Bollache, Loïc; Bond, Alexander L.; Bouwhuis, Sandra; Bradley, Russell W.; Burr, Zofia; Camphuysen, Kees; Catry, Paulo; Chiaradia, Andre; Christensen-Dalsgaard, Signe; Cuthbert, Richard; Dehnhard, Nina; Descamps, Sébastien; Diamond, Tony; Divoky, George; Drummond, Hugh; Dugger, Katie M.; Dunn, Michael J.; Emmerson, Louise; Erikstad, Kjell Einar; Fort, Jérôme; Fraser, William; Genovart, Meritxell; Gilg, Olivier; González-Solís, Jacob; Granadeiro, José Pedro; Grémillet, David; Hansen, Jannik; Hanssen, Sveinn Are; Harris, Mike; Hedd, April; Hinke, Jefferson; Igual, José Manuel; Jahncke, Jaime; Jones, Ian; Kappes, Peter J.; Lang, Johannes; Langset, Magdalene; Lescroël, Amélie; Lorentsen, Svein-Håkon; Lyver, Phil O’B.; Mallory, Mark; Moe, Børge; Montevecchi, William A.; Monticelli, David; Mostello, Carolyn; Newell, Mark; Nicholson, Lisa; Nisbet, Ian; Olsson, Olof; Oro, Daniel; Pattison, Vivian; Poisbleau, Maud; Pyk, Tanya; Quintana, Flavio; Ramos, Jaime A.; Ramos, Raül; Reiertsen, Tone Kirstin; Rodríguez, Cristina; Ryan, Peter; Sanz-Aguilar, Ana; Schmidt, Niels M.; Shannon, Paula; Sittler, Benoit; Southwell, Colin; Surman, Christopher; Svagelj, Walter S.; Trivelpiece, Wayne; Warzybok, Pete; Watanuki, Yutaka; Weimerskirch, Henri; Wilson, Peter R.; Wood, Andrew G.; Philimore, Albert B.; Lewis, Sue (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-04-02)
      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, ...
    • Gravrøys med spor etter gravlegging i eldre og yngre jernalder. Arkeologisk undersøkelse på Vestnes på Bjarkøy, Harstad k. 

      Niemi, Anja Roth (Research report; Forskningsrapport, 2016-05-30)
      I 2012 ble det foretatt en sikringsundersøkelse i en gravrøys som var sterkt skadet på Vestnes på Bjarkøy. Omtrent halve gravrøysa var bevart. Røysa har opprinnelig hatt en diameter på rundt 8 meter, og var rundt 80 cm høy. Det ble dokumentert et brannlag bestående av trekull og brente bein i bunnen av røysa, som ble datert til eldre førromersk jernalder. Noe høyere i røysa ble det funnet ...

    • Has climate change resulted in a mismatch between the spring arrival of the Common Cuckoo Cuculus canorus and its hosts in North Norway? 

      Barrett, Robert T. (Journal article; Tidsskriftartikkel; Peer reviewed, 2014)
      Analysis of spring arrival dates in North Norway showed advanced arrival of the Common Cuckoo Cuculus canorus but not of four of its most frequently used hosts. No evidence was found of a climate-driven mismatch that might contribute to the decline in the Norwegian Cuckoo population.

    • High-throughput sequencing of African chikanda cake highlights conservation challenges in orchids 

      Veldman, Sarina; Gravendeel, Barbara; Otieno, Joseph; Lammers, Youri; Duijm, Elza; Nieman, Aline; Bytebier, Benny; Ngugi, Grace; Martos, Florent; van Andel, TR; de Boer, Hugo (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-04-01)
      Chikanda is a traditional dish made with wild-harvested ground orchid tubers belonging to three orchidioid genera, Disa, Satyrium and Habenaria, all of which are CITES appendix II-listed. Identification of collected orchid tubers is very difficult and documentation of constituent species in prepared chikanda has hitherto been impossible. Here amplicon metabarcoding was used in samples of six prepared ...
    • Holocene floristic diversity and richness in northeast Norway revealed by sedimentary ancient DNA (sedaDNA) and pollen 

      Clarke, Charlotte; Edwards, Mary Elizabeth; Brown, Antony Gavin; Gielly, Ludovic; Lammers, Youri; Heintzman, Peter D.; Murguzur, Francisco Javier Ancin; Bråthen, Kari Anne; Goslar, Tomasz; Alsos, Inger Greve (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-30)
      We present a Holocene record of floristic diversity and environmental change for the central Varanger Peninsula, Finnmark, based on ancient DNA extracted from the sediments of a small lake (<i>sed</i>aDNA). The record covers the period c. 10 700 to 3300 cal. a BP and is complemented by pollen data. Measures of species richness, sample evenness and beta diversity were calculated based on <i>sed</i>aDNA ...
    • 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 ...
    • Human–environment dynamics during the Iron Age in the Lofoten Islands, Norway 

      Balascio, Nicholas L.; Wickler, Stephen (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-01)
      Integrated archaeological and paleoenvironmental investigations provide long-term perspectives on human–environment interactions. In the North Atlantic region, early human settlements were established in marginal agricultural environments and were susceptible to various environmental stressors. The Lofoten Islands have had an important role in the history of this region, particularly during the ...

    • Hva gjør vi med reindriften? 

      Bjørklund, Ivar (Chronicle; Kronikk, 2013)
      Den samiske reindriften står i dag ved en skillevei – sammen med norske myndigheter. Veivalget handler om man fortsatt vil opprettholde den siste samiske kulturbærende næring eller om man vil handle på tvers av folkerettslige forpliktelser, lovfestede rettigheter og allmenn politisk anstendighet. Reindriftens skjebne er at den alltid har vært forvaltet og forstått gjennom de ideologiske oppfatninger ...
