Global change: Translating plant ecophysiological responses to ecosystems.

The physiological responses of plants to elevated CO(2) have not been incorporated into most models of ecosystem function under changed climate. These responses are now well documented, and recent work demonstrates that they can be readily included in ecosystem models. Simulations show that the effects of elevated CO(2) levels on transpiration and gas exchange will increase the sensitivity of community structure (particularly of forests) to climate change.
