    • 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 ...

    • 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 ...

    • 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 ...
