Global negative vegetation feedback to climate warming responses of leaf litter decomposition rates in cold biomes.

abstract：:Understanding the sensitivity of tundra vegetation to climate warming is critical to forecasting future biodiversity and vegetation feedbacks to climate. In situ warming experiments accelerate climate change on a small scale to forecast responses of local plant communities. Limitations of this approach include the app...
