    • Changes in plant composition and diversity in an alpine heath and meadow after 18 years of experimental warming 

      Alatalo, Juha M.; Erfanian, Mohammad Bagher; Molau, Ulf; Chen, Shengbin; Bai, Yang; ... more authors ( Springer , 2021 , Article)
      Global warming is expected to have large impacts on high alpine and Arctic ecosystems in the future. Here we report effects of 18 years of experimental warming on two contrasting high alpine plant communities in subarctic ...

    • Decomposition rate and stabilization across six tundra vegetation types exposed to >20 years of warming 

      Sarneel, Judith M.; Sundqvist, Maja K.; Molau, Ulf; Björkman, Mats P.; Alatalo, Juha M. ( Elsevier , 2020 , Article)
      © 2020 The Authors Aims: Litter decomposition is an important driver of soil carbon and nutrient cycling in nutrient-limited Arctic ecosystems. However, climate change is expected to induce changes that directly or indirectly ...

    • Impact of ambient temperature, precipitation and seven years of experimental warming and nutrient 

      Alatalo, Juha; Dai, Junhu; Pandey, Rajiv; Erfanian, Mohammad Bagher; Ahmed, Talaat; ... more authors ( Elsevier , 2021 , Article)
      Global change is causing changes in temperature, precipitation, and nutrient availability. Alpine and polar regions are predicted to be among the most vulnerable for these changes. We applied a seven-year factorial experiment ...

    • Impact of ambient temperature, precipitation and seven years of experimental warming and nutrient addition on fruit production in an alpine heath and meadow community 

      Juha M., Alatalo; Dai, Junhu; Pandey, Rajiv; Erfanian, Mohammad Bagher; Ahmed, Talaat; ... more authors ( Elsevier , 2022 , Article)
      Alpine and polar regions are predicted to be among the most vulnerable to changes in temperature, precipitation, and nutrient availability. We carried out a seven-year factorial experiment with warming and nutrient addition ...

    • Responses of lichen communities to 18 years of natural and experimental warming 

      Alatalo, Juha M.; Jägerbrand, Annika K.; Chen, Shengbin; Molau, Ulf ( Oxford University Press , 2017 , Article)
      Background and Aims Climate change is expected to have major impacts on high alpine and arctic ecosystems in the future, but empirical data on the impact of long-term warming on lichen diversity and richness are sparse. ...

    • 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 ...

    • Tundra Trait Team: A database of plant traits spanning the tundra biome 

      Bjorkman A.D.; Myers-Smith I.H.; Elmendorf S.C.; Normand S.; Thomas H.J.D.; ... more authors ( Blackwell Publishing Ltd , 2018 , Article)
      Motivation: The Tundra Trait Team (TTT) database includes field-based measurements of key traits related to plant form and function at multiple sites across the tundra biome. This dataset can be used to address theoretical ...
