    • 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 ...

    • Experimental warming differentially affects vegetative and reproductive phenology of tundra plants 

      Collins, Courtney G.; Elmendorf, Sarah C.; Hollister, Robert D.; Henry, Greg H.R.; Clark, Karin; ... more authors ( Nature Research , 2021 , Article)
      Rapid climate warming is altering Arctic and alpine tundra ecosystem structure and function, including shifts in plant phenology. While the advancement of green up and flowering are well-documented, it remains unclear ...

    • Global maps of soil temperature 

      Lembrechts, Jonas J.; van den Hoogen, Johan; Aalto, Juha; Ashcroft, Michael B.; De Frenne, Pieter; ... more authors ( Wiley , 2022 , Article)
      Research in global change ecology relies heavily on global climatic grids derived from estimates of air temperature in open areas at around 2 m above the ground. These climatic grids do not reflect conditions below vegetation ...

    • Short-term herbivory has long-term consequences in warmed and ambient high Arctic tundra 

      Little, Chelsea J; Cutting, Helen; Alatalo, Juha; Cooper, Elisabeth J ( Institute of Physics Publishing , 2017 , Article)
      Climate change is occurring across the world, with effects varying by ecosystem and region but already occurring quickly in high-latitude and high-altitude regions. Biotic interactions are important in determining ecosystem ...

    • 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 ...

    • Winters are changing: snow effects on Arctic and alpine tundra ecosystems 

      Rixen, Christian; Høye, Toke Thomas; Macek, Petr; Aerts, Rien; Alatalo, Juha; ... more authors ( Canadian Science Publishing , 2022 , Article)
      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 ...
