Plant community responses to experimental warming across the tundra biome
Marilyn D. Walker,C. Henrik Wahren,Robert D. Hollister,Greg H. R. Henry,Lorraine E. Ahlquist,Juha M. Alatalo,M. Syndonia Bret-Harte,Monika P. Calef,Terry V. Callaghan,Amy B Carroll,Howard E.

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.
Journal ArticleDOI

A. M. Arft,Marilyn D. Walker,Jessica Gurevitch,Juha M. Alatalo,M. S. Bret-Harte,Mark R. T. Dale,M. Diemer,Felix Gugerli,Gregory H. R. Henry,Michael H. Jones,Robert D. Hollister,Ingibjörg S.

Walker,P. J. Webber,Jeffrey M. Welker,Philip A. Wookey +28 more
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 change and arctic ecosystems: is lichen decline a function of increases in vascular plant biomass?
Johannes H. C. Cornelissen,Johannes H. C. Cornelissen,Terry V. Callaghan,Juha M. Alatalo,Anders Michelsen,Enrico Graglia,Anne E. Hartley,David S. Hik,Sarah E. Hobbie,Malcolm C. Press,Clare H. Robinson,Gregory H. R. Henry,Gus Shaver,Gareth K. Phoenix,D. Gwynn Jones,Sven Jonasson,F. S. Chapin,Ulf Molau,Christopher Neill,John A. Lee,Jerry M. Melillo,B. Sveinbjörnsson,Rien Aerts +22 more
TL;DR: Cornelissen et al. as discussed by the authors showed that lichen decline in arctic ecosystems is a function of increases in vascular plant biomass, and proposed a global change and arctic ecology model.
Journal ArticleDOI
Global negative vegetation feedback to climate warming responses of leaf litter decomposition rates in cold biomes

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.
