      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 bryophyte species are relatively difficult to identify, they are often lumped into one functional group. Consequently, bryophyte function remains poorly resolved. Here, we explore ...

      Collins, Courtney G.; Elmendorf, Sarah C.; Hollister, Robert D.; Henry, Greg H. R.; Clark, Karin; Bjorkman, Anne D.; Myers-Smith, Isla H.; Prevéy, Janet S.; Ashton, Isabel W.; Assmann, Jakob J.; Alatalo, Juha M.; Carbognani, Michele; Chisholm, Chelsea L.; Cooper, Elisabeth J.; Forrester, Chiara; Jónsdóttir, Ingibjörg Svala; Klanderud, Kari; Kopp, Christopher W.; Livensperger, Carolyn; Mauritz, Marguerite; May, Jeremy L.; Molau, Ulf; Oberbauer, Steven F.; Ogburn, Emily; Panchen, Zoe A.; Petraglia, Alessandro; Post, Eric; Rixen, Christian; Rodenhizer, Heidi; Schuur, Edward A.G.; Semenchuk, Philipp; Smith, Jane G.; Steltzer, Heidi; Totland, Ørjan; Walker, Marilyn D.; Welker, Jeffrey M.; Suding, Katharine N. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-11)
      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 whether all phenophases, particularly those later in the season, will shift in unison or respond divergently to warming. Here, we present the largest synthesis to our knowledge of ...

    • Long-term herbivore removal experiments reveal how geese and reindeer shape vegetation and ecosystem CO2-fluxes in high-Arctic tundra 

      Petit Bon, Matteo; Hansen, Brage Bremset; Loonen, M. J. J. E; Petraglia, Alessandro; Bråthen, Kari Anne; Böhner, Hanna; Layton-Matthews, Kate; Beard, Karen H.; Le Moullec, Mathilde; Jonsdottir, Ingibjorg Svala; Van der Wal, René (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-23)
      1. Given the current rates of climate change, with associated shifts in herbivore population densities, understanding the role of different herbivores in ecosystem functioning is critical for predicting ecosystem responses. Here, we examined how migratory geese and resident, non-migratory reindeer—two dominating yet functionally contrasting herbivores—control vegetation and ecosystem processes in ...

      The tundra is warming more rapidly than any other biome on Earth, and the potential ramifications are far-reaching because of global feedback effects between vegetation and climate. A better understanding of how environmental factors shape plant structure and function is crucial for predicting the consequences of environmental change for ecosystem functioning. Here we explore the biome-wide relationships ...

(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-10-19)
      Open top chambers (OTCs) were adopted as the recommended warming mechanism by the International Tundra Experiment (ITEX) network in the early 1990’s. Since then, OTCs have been deployed across the globe. Hundreds of papers have reported the impacts of OTCs on the abiotic environment and the biota. Here we review the impacts of the OTC on the physical environment, with comments on the appropriateness ...

      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 a common protocol to measure plant phenology in tundra study areas across the globe. Today, this valuable collection of phenology measurements depicts the responses of ...

      <p><i>Motivation</i>: 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 questions about plant strategy and trade‐offs, trait–environment relationships and environmental filtering, and trait variation across spatial scales, to validate satellite ...
