    • Consistent trait-environment relationships within and across tundra plant communities 

      Kemppinen, Julia; Niittynen, Pekka; le Roux, Peter C.; Momberg, Mia; Happonen, Konsta; Aalto, Juha; Rautakoski, Helena; Enquist, Brian J.; Vandvik, Vigdis; Rechsteiner, Aud Helen Halbritter; Maitner, Brian S.; Luoto, Miska (Journal article; Peer reviewed, 2021)
      A fundamental assumption in trait-based ecology is that relationships between traits and environmental conditions are globally consistent. We use field-quantified microclimate and soil data to explore if trait–environment ...

    • Geomorphological processes shape plant community traits in the Arctic 

      Kemppinen, Julia; Niittynen, Pekka; Happonen, Konsta; le Roux, Peter C.; Aalto, Juha; Hjort, Jan; Maliniemi, Tuija; Karjalainen, Olli; Rautakoski, Helena; Luoto, Miska (Journal article; Peer reviewed, 2022)
      Aim Geomorphological processes profoundly affect plant establishment and distributions, but their influence on functional traits is insufficiently understood. Here, we unveil trait–geomorphology relationships in Arctic ...

    • Global maps of soil temperature 

      Lembrechts, Jonas J.; van den Hoogen, Johan; Aalto, Juha; Ashcroft, Michael B.; De Frenne, Pieter; Kemppinen, Julia; Kopecký, Martin; Luoto, Miska; Maclean, Ilya M. D.; Crowther, Thomas W.; Bailey, Joseph J.; Haesen, Stef; Klinges, David H.; Niittynen, Pekka; Scheffers, Brett R.; Van Meerbeek, Koenraad; Aartsma, Peter; Abdalaze, Otar; Abedi, Mehdi; Aerts, Rien; Ahmadian, Negar; Ahrends, Antje; Alatalo, Juha M.; Alexander, Jake M.; Altman, Jan; Allonsius, Camille Nina; Ammann, Christof; Andres, Christian; Andrews, Christopher; Ardö, Jonas; Arriga, Nicola; Arzac, Alberto; Aschero, Valeria; Leandro de Assis, Rafael; Bjerke, Jarle W.; Cooper, Elisabeth J.; Graae, Bente Jessen; Rechsteiner, Aud Helen Halbritter; Haugum, Siri Vatsø; Lang, Simone; Lynn, Joshua Scott; Moriana Armendariz, Mikel; Petit Bon, Matteo; Smith, Stuart; Sørensen, Mia Vedel; Speed, James David Mervyn; Vandvik, Vigdis; Wedegärtner, Ronja Elisabeth Magdalene; Nijs, Ivan; Lenoir, Jonathan (Journal article; Peer reviewed, 2021)
      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 ...

    • 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 ...
