Plant community responses to experimental warming across the tundra biome
Recent observations of changes in some tundra ecosystems appear to be responses to a warming climate. Several experimental studies have shown that tundra plants and ecosystems can respond strongly toExpand

Recent Plant Diversity Changes on Europe’s Mountain Summits
Climb Every Mountain Mountaintop floras across Europe appear to be responding to climatic change in terms of upslope species range shifts. Pauli et al. (p. 353) systematically analyzed data gatheredExpand

Global negative vegetation feedback to climate warming responses of leaf litter decomposition rates in cold biomes.
Whether climate change will turn cold biomes from large long-term carbon sinks into sources is hotly debated because of the great potential for ecosystem-mediated feedbacks to global climate.Expand

Responses of Dryas octopetala to ITEX environmental manipulations : a synthesis with circumpolar comparisons
We have examined organismic responses of Dryas octopetala to simulated changes in the summer climate at four tundra sites as part of the International Tundra Experiment (ITEX). Our study sites areExpand
