Intraspecific trait variability is a key feature underlying high Arctic plant community resistance to climate warming
Jonsdottir, Ingibjørg; Halbritter Rechsteiner, Aud Helen; Christiansen, Casper Tai; Althuizen, Inge; Haugum, Siri Vatsø; Henn, Jonathan J.; Björnsdóttir, Katrín; Maitner, Brian Salvin; Malhi, Yadvinder; Michaletz, Sean T.; Roos, Ruben Erik; Klanderud, Kari; Lee, Hanna; Enquist, Brian J.; Vandvik, Vigdis (Journal article; Peer reviewed, 2022)In the high Arctic, plant community species composition generally responds slowly to climate warming, whereas less is known about the community functional trait responses and consequences for ecosystem functioning. The ... -
Multiscale mapping of plant functional groups and plant traits in the High Arctic using field spectroscopy, UAV imagery and Sentinel-2A data
Thomson, Eleanor R.; Spiegel, Marcus P.; Althuizen, Inge; Bass, Polly; Chen, Shuli; Chmurzynski, Adam; Rechsteiner, Aud Helen Halbritter; Henn, Jonathan J.; Jónsdóttir, Ingibjörg S.; Klanderud, Kari; Li, Yaoqi; Maitner, Brian S.; Michaletz, Sean T.; Niittynen, Pekka; Roos, Ruben Erik; Telford, Richard James; Enquist, Brian J.; Vandvik, Vigdis; Macias-Fauria, Marc; Malhi, Yadvinder (Journal article; Peer reviewed, 2021)The Arctic is warming twice as fast as the rest of the planet, leading to rapid changes in species composition and plant functional trait variation. Landscape-level maps of vegetation composition and trait distributions ... -
Plant traits and associated data from a warming experiment, a seabird colony, and along elevation in Svalbard
Vandvik, Vigdis; Halbritter, Aud Helen; Althuizen, Inge; Christiansen, Casper Tai; Henn, Jonathan Jeffrey; Jonsdottir, Ingibjorg Svala; Klanderud, Kari; Macias-Fauria, Marc; Malhi, Yadvinder; Maitner, Brian Salvin; Michaletz, Sean T.; Roos, Ruben Erik; Telford, Richard James; Bass, Polly; Björnsdóttir, Katrin; Bustamante, Lucely Lucero Vilca; Chmurzynski, Adam; Chen, Shuli; Haugum, Siri Vatsø; Kemppinen, Julia; Lepley, Kai; Li, Yaoqi; Linabury, Mary; Matos, Ilaine Silveira; Neto-Bradley, Barbara M.; Ng, Molly; Niittynen, Pekka; Hjortland Östman, Silje Andrea; Pankova, Karolina; Roth, Nina; Castorena, Matiss; Spiegel, Marcus P.; Thomson, Eleanor R.; Vågenes, Alexander Sæle; Enquist, Brian J. (Journal article; Peer reviewed, 2023)The Arctic is warming at a rate four times the global average, while also being exposed to other global environmental changes, resulting in widespread vegetation and ecosystem change. Integrating functional trait-based ... -
Three decades of environmental change studies at alpine Finse, Norway: climate trends and responses across ecological scales
Roos, Ruben Erik; Asplund, Johan; Birkemoe, Tone; Halbritter Rechsteiner, Aud Helen; Olsen, Siri Lie; Vassvik, Linn; van Zuijlen, Kristel; Klanderud, Kari (Journal article; Peer reviewed, 2022)The International Tundra Experiment (ITEX) was established to understand how environmental change impacts Arctic and alpine ecosystems. The success of the ITEX network has allowed for several important across-site syntheses, ...
