    • Background invertebrate herbivory on dwarf birch (Betula glandulosa-nana complex) increases with temperature and precipitation across the tundra biome 

      Barrio, Isabel C.; Lindén, Elin; Te Beest, Mariska; Olofsson, Johan; Rocha, Adrian; ... more authors ( Springer Verlag , 2017 , Article)
      Chronic, low intensity herbivory by invertebrates, termed background herbivory, has been understudied in tundra, yet its impacts are likely to increase in a warmer Arctic. The magnitude of these changes is however hard to ...

    • Can bryophyte groups increase functional resolution in tundra ecosystems? 

      Lett, Signe; Jónsdóttir, Ingibjörg S.; Becker-Scarpitta, Antoine; Christiansen, Casper T.; During, Heinjo; ... more authors ( Canadian Science Publishing , 2022 , Article Review)
      The relative contribution of bryophytes to plant diversity, primary productivity, and ecosystem functioning increases towards colder climates. Bryophytes respond to environmental changes at the species level, but because ...

    • Early stage litter decomposition across biomes 

      Ika, Djukic; Kepfer-Rojas, Sebastian; Schmidt, Inger Kappel; Larsen, Klaus Steenberg; Beier, Claus; ... more authors ( Elsevier , 2018 , Article)
      Through litter decomposition enormous amounts of carbon is emitted to the atmosphere. Numerous large-scale decomposition experiments have been conducted focusing on this fundamental soil process in order to understand the ...

    • Effects of Climate and Atmospheric Nitrogen Deposition on Early to Mid-Term Stage Litter Decomposition Across Biomes 

      Kwon, Taeoh; Shibata, Hideaki; Kepfer-Rojas, Sebastian; Schmidt, Inger K.; Larsen, Klaus S.; ... more authors ( Frontiers Media , 2021 , Article)
      Litter decomposition is a key process for carbon and nutrient cycling in terrestrial ecosystems and is mainly controlled by environmental conditions, substrate quantity and quality as well as microbial community abundance ...

    • Plant traits poorly predict winner and loser shrub species in a warming tundra biome 

      García Criado, Mariana; Myers-Smith, Isla H.; Bjorkman, Anne D.; Normand, Signe; Blach-Overgaard, Anne; ... more authors ( Springer , 2023 , Article)
      Climate change is leading to species redistributions. In the tundra biome, shrubs are generally expanding, but not all tundra shrub species will benefit from warming. Winner and loser species, and the characteristics that ...

    • The tundra phenology database: More than two decades of tundra phenology responses to climate change 

      Prevéy, Janet; Elmendorf, Sarah; Bjorkman, Anne; Alatalo, Juha; Ashton, Isabel; ... more authors ( NRC Research Press , 2021 , Article)
      Observations of changes in phenology have provided some of the strongest signals of the effects of climate change on terrestrial ecosystems. The International Tundra Experiment (ITEX), initiated in the early 1990s, established ...
