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.

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.

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.

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.

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.
