Global Warming and Terrestrial Ecosystems: A Conceptual Framework for Analysis
Gaius R. Shaver,Josep G. Canadell,F. S. Chapin,Jessica Gurevitch,John Harte,Greg H. R. Henry,Phil Ineson,Sven Jonasson,Jerry M. Melillo,Louis F. Pitelka,Llindsey Rustad +10 more
TL;DR: Schulze et al. as discussed by the authors presented a conceptual framework for interpreting experimental results and predicting effects of global warming on ecosystems, both in the temporal and spatial patterns of change and in how they affect ecosystems.
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
Evaluation of the point intercept method for the estimation of plant biomass
TL;DR: In this paper, the authors used the point intercept method to estimate the mass of both stems and leaves in plant stands and showed that the number of contacts between plants and the tips of narrow pins passed into the vegetation correlates highly with biomass.
Journal ArticleDOI
Responses in microbes and plants to changed temperature, nutrient, and light regimes in the arctic
TL;DR: In this article, the authors measured simultaneous responses in biomass, nitrogen (N), and phosphorus (P) incorporation in plants and microorganisms after five years of factorial fertilizer addition, air warming, and shading.
Journal ArticleDOI
Long‐term ecosystem level experiments at Toolik Lake, Alaska, and at Abisko, Northern Sweden: generalizations and differences in ecosystem and plant type responses to global change
M.T. van Wijk,M.T. van Wijk,Karina E. Clemmensen,Gaius R. Shaver,Mathew Williams,Terry V. Callaghan,Terry V. Callaghan,F. S. Chapin,J. H. C. Cornelissen,Laura Gough,Sarah E. Hobbie,Sven Jonasson,John A. Lee,Anders Michelsen,Malcolm C. Press,Stanley Richardson,H. Rueth +16 more
TL;DR: In this paper, a meta-analysis performed on the results of long-term ecosystem-level experiments near Toolik Lake, Alaska, and Abisko, Sweden was performed to quantified aboveground biomass responses of different arctic and subarctic ecosystems to experimental fertilization, warming and shading.
