TL;DR: Warming increased height and cover of deciduous shrubs and graminoids, decreased cover of mosses and lichens, and decreased species diversity and evenness, which predict that warming will cause a decline in biodiversity across a wide variety of tundra, at least in the short term.

TL;DR: Results indicate that key phenological events such as leaf bud burst and flowering occurred earlier in warmed plots throughout the study period; however, there was little impact on growth cessation at the end of the season.
Journal ArticleDOI
Global assessment of experimental climate warming on tundra vegetation: heterogeneity over space and time.

TL;DR: In this article, a synthesis of 61 experimental warming studies, of up to 20 years duration, in tundra sites worldwide, was used to understand the sensitivity of tundras vegetation to climate warming and to forecast future biodiversity and vegetation feedbacks to climate.

TL;DR: In this paper, remote sensing data indicate that contemporary climate warming has already resulted in increased productivity and increased productivity in the tundra biome (Tundra Tundra Bi biome).

TL;DR: It is demonstrated that longer-term, large-scale changes to leaf litter decomposition will be driven primarily by both direct warming effects and concomitant shifts in plant growth form composition, with a much smaller role for changes in litter quality within species.
