By «ecosystem change», we mean changes in some or all of the following: the number and types of organisms present; the ecosystem's physical appearance (e.g., tall or short, open or dense vegetation); the functioning of the system and all its interactive parts, including the cycling of nutrients and productivity.
Altogether, therefore, common sense suggests that with the plant productivity gains that result from the aerial fertilization effect of the ongoing rise in atmospheric CO2, plus its transpiration - reducing effect that boosts plant water use efficiency, along with its stress - alleviating effect that lessens the negative growth impacts of resource limitations and environmental constraints, the world's vegetation possesses an ideal set of abilities to reap a tremendous benefit from what the President inaccurately terms «carbon pollution» in the years and decades to come.
Climate is a major factor in controlling global patterns of vegetation structure and productivity, as well as plant and animal species composition.
What will be the next effects of increased CO2 on agricultural and forest productivity, and other vegetation?
Impacts of large - scale and persistent changes in the MOC are likely to include changes to marine ecosystem productivity, fisheries, ocean carbon dioxide uptake, oceanic oxygen concentrations and terrestrial vegetation [Working Group I Fourth Assessment 10.3, 10.7; Working Group II Fourth Assessment 12.6, 19.3].

For example, it has been proposed that the vegetation of the Amazon basin is highly dependent on Saharan dust deposition, which provides phosphorus, necessary for maintenance of long - term productivity (Okin et al., 2004; Section 7.3).
Satellite measures of vegetation greenness, together with animal stocking data and key climatic factors, reveal interannual precipitation variability to be a significant constraint on global pasture productivity.
Rainfall change and variability is very likely to affect vegetation in tropical grassland and savanna systems with, for example, a reduction in cover and productivity simulated along an aridity gradient in southern African savanna in response to the observed drying trend of about 8 mm / yr since 1970 (Woodward and Lomas, 2004a).
Studies also suggest there could be impacts on the carbon cycle (Zickfeld et al, 2008) and on soil moisture and primary productivity of the terrestrial vegetation (Vellinga and Wood, 2002).»
