    • Growth rings show limited evidence for ungulates’ potential to suppress shrubs across the Arctic 

      Vuorinen, Katariina Elsa Maria; Austrheim, Gunnar; Tremblay, Jean-Pierre; Myers-Smith, Isla H.; Hortman, Hans Ivar; Frank, Peter; Barrio, Isabel C.; Dalerum, Fredrik; Björkman, Mats Peter; Björk, Robert G.; Ehrich, Dorothee; Sokolov, Aleksandr; Sokolova, Natalya; Ropars, Pascale; Boudreau, Stephane; Normand, Signe; Prendin, Angela L.; Schmidt, Niels Martin; Pacheco-Solana, Arturo; Post, Eric; John, Christian; Kerby, Jeff; Sullivan, Patrick F.; Le Moullec, Mathilde; Hansen, Brage Bremset; van der Wal, René; Pedersen, Åshild Ønvik; Sandal, Lisa; Gough, Laura; Young, Amanda; Li, Bingxi; Magnusson, Runa I.; Sass-Klaassen, Ute; Buchwal, Agata; Welker, Jeffrey; Grogan, Paul; Andruko, Rhett; Volkovitskiy, Alexander; Terekhina, Alexandra; Speed, James David Mervyn (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-02-22)
      Global warming has pronounced effects on tundra vegetation, and rising mean temperatures increase plant growth potential across the Arctic biome. Herbivores may counteract the warming impacts by reducing plant growth, but the strength of this effect may depend on prevailing regional climatic conditions. To study how ungulates interact with temperature to influence growth of tundra shrubs across ...

    • High Arctic ecosystem states: Conceptual models of vegetation change to guide long-term monitoring and research 

      Ravolainen, Virve; Soininen, Eeva Marjatta; Jónsdóttir, Ingibjörg Svala; Eischeid, Isabell; Forchhammer, Mads C.; van der Wal, René; Pedersen, Åshild Ønvik (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-01-18)
      Vegetation change has consequences for terrestrial ecosystem structure and functioning and may involve climate feedbacks. Hence, when monitoring ecosystem states and changes thereof, the vegetation is often a primary monitoring target. Here, we summarize current understanding of vegetation change in the High Arctic—the World’s most rapidly warming region—in the context of ecosystem monitoring. To ...

    • Mapping species distributions: a comparison of skilled naturalist and lay citizen science recording 

      van der Wal, René; Anderson, Helen; Robinson, Annie; Sharma, Nirwan; Mellish, Chris; Roberts, Stuart; Darvill, Ben; Siddharthan, Advaith (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-10-27)
      To assess the ability of traditional biological recording schemes and lay citizen science approaches to gather data on species distributions and changes therein, we examined bumblebee records from the UK’s national repository (National Biodiversity Network) and from BeeWatch. The two recording approaches revealed similar relative abundances of bumblebee species but different geographical distributions. ...

    • Rich local knowledge despite high transience in an Arctic community experiencing rapid environmental change 

      Lennert, Ann Eileen; van der Wal, René; Zhang, Jasmine; Hausner, Vera Helene; Ancin Murguzur, Francisco Javier; Miles, Martin (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-11-04)
      Environmental monitoring and long-term research produce detailed understanding, but its collective effort does not add up to ‘the environment’ and therefore may be difficult to relate to. Local knowledge, by contrast, is multifaceted and relational and therefore can help ground and complement scientific knowledge to reach a more complete and holistic understanding of the environment and changes ...

    • Waters that matter: How human-environment relations are changing in high-Arctic Svalbard 

      Sokolickova, Zdenka; Ramirez Hincapié, Esteban; Zhang, Jasmine; Lennert, Ann Eileen; Löf, Annette; van der Wal, René (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-12-20)
      There is scientific consensus that the archipelago of Svalbard is warming up faster than other parts of the planet. People who live in or regularly visit this part of the European high Arctic observe and experience these changes in a subjective and relational manner. This article illustrates how perceptions of environmental change are enmeshed with our ways of interacting with water(s) and dwelling ...
