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: 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.

TL;DR: Biome-wide relationships between temperature, moisture and seven key plant functional traits across the tundra and over time show that community height increased with warming across all sites, whereas other traits lagged behind predicted rates of change.

TL;DR: In this paper, the sensitivity of Icelandic tundra communities to climate warming varies greatly depending on initial conditions in terms of species diversity, dominant species, soil and climate conditions as well as land-use history.
