Intraspecific trait variability is a key feature underlying high Arctic plant community resistance to climate warming
Ingibjörg S. Jónsdóttir,Aud H. Halbritter,Casper T. Christiansen,Inge H. J. Althuizen,Siri V. Haugum,Jonathan J. Henn,Katrín Björnsdóttir,Brian S. Maitner,Yadvinder Malhi,Sean T. Michaletz,Ruben E. Roos,Kari Klanderud,Hanna Lee,Brian J. Enquist,Vigdis Vandvik +14 more
TL;DR: 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 as discussed by the authors , which suggests a significant role of intraspecific trait variability in functional responses to climate change.

- 01 May 2018
TL;DR: In this article, Útdráttur et al. studied the response to climate warming in high and sub-Arctic habitats, focusing on the Arctic in a warming world.

TL;DR: The dataset contains 1,962 plant records and 16,160 trait measurements from 34 vascular plant taxa, for 9 of which these are the first published trait data, which can offer insights into ecosystem functioning and provide baselines to assess climate and environmental change impacts.

TL;DR: As the Arctic warms, boreal species are expanding into tundra ecosystems, a process called tundra borealization, driven by climate and land-use change, with implications for food webs, ecosystem functions, and northern livelihoods.
