    • Borrelia burgdorferi sensu lato-infected Ixodes ricinus collected from vegetation near the Arctic Circle 

      Hvidsten, Dag; Stordal, Frode; Lager, Malin; Rognerud, Bjørg; Kristiansen, Bjørn Erik; Matussek, Andreas; Gray, Jeremy; Stuen, Snorre (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-07-06)
      This is the first study to determine the density of questing Ixodes ricinus in northern Norway. It was performed at two sites in Brønnøy, which has been known for its tick permissive habitats for decades and is one of the northernmost habitats with an abundant I. ricinus population in the world. From April to November 2011, all stages of host-seeking I. ricinus were collected from the two sites. ...

    • Complexity revealed in the greening of the Arctic 

      Myers-Smith, Isla H.; Kerby, Jeffrey T.; Phoenix, Gareth K.; Bjerke, Jarle W.; Epstein, Howard E.; Assmann, Jakob J.; John, Christian; Andreu-Hayles, Laia; Angers-Blondin, Sandra; Beck, Pieter S. A.; Berner, Logan T.; Bhatt, Uma S.; Bjorkman, Anne D.; Blok, Daan; Bryn, Anders; Christiansen, Casper Tai; Cornelissen, J. Hans C.; Cunliffe, Andrew M.; Elmendorf, Sarah C.; Forbes, Bruce C.; Goetz, Scott J.; Hollister, Robert D.; de Jong, Rogier; Loranty, Michael M.; Macias-Fauria, Marc; Maseyk, Kadmiel; Normand, Signe; Olofsson, Johan; Parker, Thomas C.; Parmentier, Frans-Jan W.; Post, Eric; Schaepman-Strub, Gabriela; Stordal, Frode; Sullivan, Patrick F.; Thomas, Haydn J.D.; Tømmervik, Hans; Treharne, Rachael; Tweedie, Craig E.; Walker, Donald A.; Wilmking, Martin; Wipf, Sonja (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-01-31)
      As the Arctic warms, vegetation is responding, and satellite measures indicate widespread greening at high latitudes. This ‘greening of the Arctic’ is among the world’s most important large-scale ecological responses to global climate change. However, a consensus is emerging that the underlying causes and future dynamics of so-called Arctic greening and browning trends are more complex, variable ...

    • Direct and indirect impacts of climate change on wheat yield in the Indo-Gangetic plain in India 

      Daloz, Anne Sophie; Rydsaa, Johanne Hope; Hodnebrog, Øivind; Sillmann, Jana; Oort, Bob Eric Helmuth van; Mohr, Christian Wilhelm; Agrawal, M.; Emberson, L.; Stordal, Frode; Zhang, T. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-28)
      The Indo-Gangetic Plain (IGP) is one of the main wheat-production regions in India and the world. With climate change, wheat yields in this region will be affected through changes in temperature and precipitation and decreased water availability for irrigation, raising major concerns for national and international food security. Here we use a regional climate model and a crop model to better understand ...

    • The distribution limit of the common tick, Ixodes ricinus, and some associated pathogens in north-western Europe 

      Hvidsten, Dag; Frafjord, Karl; Gray, Jeremy S.; Henningsson, Anna Jonsson; Jenkins, Andrew; Kristiansen, Bjørn Erik; Lager, Malin; Rognerud, Bjørg; Slåtsve, Arne Martin; Stordal, Frode; Stuen, Snorre; Wilhelmsson, Peter (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-02-03)
      In north-western Europe, the common tick, <i>Ixodes ricinus</i>, is widely established, its distribution appears to be increasing and the spread of tick-borne diseases is of increasing concern. The project <i>‘Flått i Nord’</i> (Ticks in northern Norway) commenced in spring 2009 with the intention of studying the tick’s distribution and that of its pathogens in northern Norway. Several methods were ...
