Thomesmes and freshwater ecosystems, and were based on global scenarios of changes in the environment and current understanding about the specific biome sensitivity to global change. The first step was to identify the major drivers of biodiversity change at the global scale: changes in land use, climate,

At regional-to-global scales climate exerts a dominant influence over the distribution of these plant functional types (Woodward 1987). Smaller-scale variations in distribution may be controlled by smaller-scale features of the environment (e.g., soils and topography). Specific climatic cont

Tropical Savanna,wet summers and cool dry winters, and (2) a mixed life-form vegetation in which both woody and herbaceous plants play a significant ecological role. In tropical and subtropical savannas the herbaceous layer is dominated by C. grasses, whereas the woody plants are C. trees and shrubs. In temperate sa
