Global negative vegetation feedback to climate warming responses of leaf litter decomposition rates in cold biomes
Johannes H. C. Cornelissen,Peter M. van Bodegom,Rien Aerts,Terry V. Callaghan,Richard S. P. van Logtestijn,Juha M. Alatalo,F. Stuart Chapin,Renato Gerdol,Jon Tomas Gudmundsson,Dylan Gwynn-Jones,Anne E. Hartley,David S. Hik,Annika Hofgaard,Ingibjörg S. Jónsdóttir,Staffan Karlsson,Julia A. Klein,James A.

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.

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.

Biomass and co2 flux in wet sedge tundras: responses to nutrients, temperature, and light
Gus Shaver,Loretta C. Johnson,Deb H. Cades,G. L. Murray,James A. Laundre,Edward B. Rastetter,Knute J. Nadelhoffer,Anne E. Giblin +7 more
TL;DR: In this paper, the effects of increased N or P availability, increased air temperature, and decreased light intensity on wet sedge tundra in northern Alaska were analyzed for six growing seasons, using plastic greenhouses at two sites, both with and without N + P fertilizer.

Effects on the structure of arctic ecosystems in the short- and long-term perspectives
Terry V. Callaghan,Lars Olof Björn,Yuri Chernov,Terry Chapin,Torben R. Christensen,Brian Huntley,Rolf A. Ims,Margareta Johansson,Dyanna Jolly,Sven Jonasson,Nadya Matveyeva,Nicolai Panikov,Walter C. Oechel,Gus Shaver,Heikki Henttonen +14 more
TL;DR: For example, this paper found that increased plant productivity due to warmer summers may dominate food-web dynamics in tundra and sub-Arctic forest ecosystems, but the effects vary regionally, with the greatest response of plant and invertebrate communities being observed at the coldest locations.
