      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 ...

    • A review of open top chamber (OTC) performance across the ITEX Network 

      Hollister, Robert D.; Elphinstone, Cassandra; Henry, Greg H.R.; Bjorkman, Anne D.; Klanderud, Kari; Björk, Robert G.; Björkman, Mats P.; Bokhorst, Stef; Carbognani, Michele; Cooper, Elisabeth; Dorrepaal, Ellen; Elmendorf, Sarah C.; Fetcher, Ned; Gallois, Elise C.; Gudmundsson, Jon Steinar; Healey, Nathan C.; Jonsdottir, Ingibjorg Svala; Klarenberg, Ingeborg J.; Oberbauer, Steven F.; Macek, Petr; May, Jeremy L.; Mereghetti, Alessandro; Molau, Ulf; Petraglia, Alessandro; Rinnan, Riikka; Rixen, Christian; Wookey, Philip A. (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 ...

    • Site-specific responses of fungal and bacterial abundances to experimental warming in litter and soil across arctic and alpine tundra 

      Jeanbille, Mathilde; Clemmensen, Karina E; Juhanson, Jaanis; Michelsen, Anders; Cooper, Elisabeth J.; Henry, Greg H.R.; Hofgaard, Annika; Hollister, Robert D.; Jónsdóttir, Ingibjörg Svala; Klanderud, Kari; Tolvanen, Anne; Hallin, Sara (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-01)
      Vegetation change of the Arctic tundra due to global warming is a well-known process, but the implication for the belowground microbial communities, key in nutrient cycling and decomposition, is poorly understood. We characterized the fungal and bacterial abundances in litter and soil layers across 16 warming experimental sites at 12 circumpolar locations. We investigated the relationship between ...

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

      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 end, and plant access to moisture and nutrients. Here, we review the current knowledge of the snow cover’s role for vegetation, plant-animal interactions, permafrost conditions, ...
