https://doi.org/10.1007/978-3-662-47331-3 forests have also been implicated as the “missing sink” for atmospheric carbon dioxide (Ciais et al. 1995). For these reasons, there has been considerable interest and speculation about future changes in the extent, structure, and functioning of the boreal forest.

Modeling the Response of Vegetation Distribution and Biodiversity to Climate Change,tition mediated by the effects of climate. Ecophysiological constraints on individual plant functional types account for the gross qualitative features of biome distribution, and such constraints have been incorporated into a number of rule-based vegetation models (Woodward 1987); (Neilson et al. 1992); (Prentice et al. 1992).

The Use of Global-Change Scenarios to Determine Changes in Species and Habitats,ecomes degraded. Resource management ultimately thus defines the fate of biodiversity. Such degradation could also increase the vulnerability of biodiversity to other stresses (e.g., environmental change).

Mediterranean-Climate Ecosystems, 1995), each region has a unique history of human habitation and use. There is a long history of comparative biotic studies among these regions upon which we draw; however, there are no comparisons of the social drivers of land-use change among these areas. Our analyses are therefore less complete than we would like.

Temperate Forests of North and South America,rate trees provide an invaluable and irreplaceable record of climatic changes during the last millenium. In addition, temperate forests are currently the major source of timber and related wood products worldwide. Thus, their long-term sustainability is of utmost economic importance, both regionally and globally.

Tropical Savanna,n tropical and subtropical savannas the herbaceous layer is dominated by C. grasses, whereas the woody plants are C. trees and shrubs. In temperate savannas the grasses are generally also C.. Because of their greater extent this chapter will focus on the tropical/subtropical savannas.
