Definitions and taxonomyThe tundra is defined as the region beyond the elevational and latitudinal treeline116. We consider shrubs as multi-stemmed woody plants under 5–6 m in height117. We followed the taxonomy outlined in The Plant List (http://www.theplantlist.org/) at the species level and standardised synonyms according to this reference. Definitions of the three traits follow Kattge et al.118 which in turn follow Garnier et al.119.

Editor’s summaryArctic tundra is experiencing rapid climate change, including warming temperatures and loss of sea ice. Plants and herbivores are both affected by these abiotic changes. Post et al. examined the effects of climate change and herbivory on the diversity of tundra plants, fungi, and lichens using a 15-year warming and herbivore exclusion experiment. They found that diversity decreased over time across all treatments, which was mainly explained by losses of sea ice with ambient warming.
