• Stochastic rain events increase NDVI through moss water content: a High-Arctic field experiment 

      Valøen, Kristine (Master thesis, 2019)
      Målinger av ”Normalized Difference Vegetation Index” (NDVI) gjennom fjernmålinger blir brukt til å indikere produktiviteten til vegetasjonen i Høyarktis, og hvordan den påvirkes av klimaendringer. Tolkningen av observerte ...
    • Strengthening the evidence base for temperature-mediated phenological asynchrony and its impacts 

      Samplonius, Jelmer; Atkinson, Angus; Hassall, Christopher; Keogan, Katherine; Thackeray, Stephen J.; Assmann, Jakob J.; Burgess, Malcolm D.; Macphie, Kirsty H; Pearce-Higgins, James W.; Simmonds, Emily Grace; Johansson, Jacob; Varpe, Øystein; Weir, James C; Childs, Dylan Z.; Cole, Ella F.; Daunt, Francis; Hart, Tom; Lewis, Owen T.; Pettorelli, Nathalie; Sheldon, Ben C.; Phillimore, Albert B. (Journal article; Peer reviewed, 2020)
      Climate warming has caused the seasonal timing of many components of ecological food chains to advance. In the context of trophic interactions, the match–mismatch hypothesis postulates that differential shifts can lead to ...
    • The Role of the Arctic Fox in the Breeding Success of the Snow Bunting 

      Lenz, Kay Banu (Master thesis, 2022)
      The reproductive success of breeding birds can be determined by many different factors. One factor often associated with the failure of a brood is nest depredation. To avoid depredation, different bird species implement ...
    • Towards rainy Arctic winters: effects of experimental icing on tundra plants and their soil conditions 

      Le Moullec, Mathilde; Isaksen, Ketil; Petit Bon, Matteo; Jónsdóttir, Ingibjörg Svala; Varpe, Øystein; Hendel, Anna-Lena; Beumer, Larissa Teresa; Hansen, Brage Bremset (MET report;, Research report, 2019)
      Global warming comes with more frequent extreme climate events. In the Arctic, extreme warm spells with heavy rain-on-snow events in winter can cause dramatic changes to the snow-pack and encapsulate the vegetation in thick ...
    • Variation and correlation in the timing of breeding of North Atlantic seabirds across multiple scales 

      Keogan, Katharine; Daunt, Francis; Wanless, Sarah; Phillips, Richard A.; Alvarez, David; Anker-Nilssen, Tycho; Barrett, Robert; Bech, Claus; Becker, Peter H.; Berglund, Per-Arvid; Bouwhuis, Sandra; Burr, Zofia M.; Chastel, Olivier; Christensen-Dalsgaard, S*; Christensen-Dalsgaard, Signe; Descamps, Sebastien; Diamond, Tony; Elliott, Kyle; Erikstad, Kjell E.; Harris, Mike; Hentati-Sundberg, Jonas; Heubeck, Martin; Kress, Stephen W.; Langset, Magdalene; Lorentsen, Svein-Håkon; Major, Heather L.; Mallory, Mark; Mellor, Mick; Miles, Will T.S.; Moe, Børge; Mostello, Carolyn; Newell, Mark; Nisbet, Ian; Reiertsen, Tone Kristin; Rock, Jennifer; Shannon, Paula; Varpe, Øystein; Lewis, Sue; Phillimore, Albert B. (Peer reviewed; Journal article, 2022)
      1. Timing of breeding, an important driver of fitness in many populations, is widely studied in the context of global change, yet despite considerable efforts to identify environmental drivers of seabird nesting phenology, ...
    • Warmer and wetter winters: characteristics and implications of an extreme weather event in the High Arctic 

      Hansen, Brage Bremset; Isaksen, Ketil; Benestad, Rasmus E.; Kohler, Jack; Pedersen, Åshild Ø.; Loe, Leif Egil; Coulson, Stephen James; Larsen, Jan Otto; Varpe, Øystein (Journal article; Peer reviewed, 2014)
      One predicted consequence of global warming is an increased frequency of extreme weather events, such as heat waves, droughts, or heavy rainfalls. In parts of the Arctic, extreme warm spells and heavy rain-on-snow (ROS) ...
