Joshua; Lock, Janine G.; Kuoppamaa, Mari S.; Kristensen, Jeppe A.; Bjorkman, Anne D.; Myers-Smith, Isla; Lecomte, Nicolas; Axmacher, Jan C.; Den Herder, Michael; Pagneux, Emmanuel P.; Skarin, Anna; Sokolova, Natalia; Windirsch, Torben; Wheeler, Helen Claire; Serrano, Emmanuel; Virtanen, Tarmo; Hik, David S.; Kaarlejärvi, Elina; Speed, James David Mervyn; Soininen, Eeva M; Gilg, Olivier (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-03-25)
      Background Northern ecosystems are strongly influenced by herbivores that differ in their impacts on the eco‑ system. Yet the role of herbivore diversity in shaping the structure and functioning of tundra ecosystems has been overlooked. With climate and land-use changes causing rapid shifts in Arctic species assemblages, a better under‑ standing of the consequences of herbivore diversity changes for ...

(Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
      Recent research using repeat photography, long-term ecological monitoring and dendrochronology has documented shrub expansion in arctic, high-latitude and alpine tundra ecosystems. Here, we (1) synthesize these findings, (2) present a conceptual framework that identifies mechanisms and constraints on shrub increase, (3) explore causes, feedbacks and implications of the increased shrub cover in tundra ...

      Snow is an important driver of ecosystem processes in cold biomes. Snow accumulation determines ground temperature, light conditions and moisture availability during winter. It also affects the growing season’s start and end, and plant access to moisture and nutrients. Here, we review the current knowledge of the snow cover’s role for vegetation, plant-animal interactions, permafrost conditions, ...
