Mediterranean-type climates, which are characterized by a predominantly winter rainfall regime, exist in five regions of the world: parts of California, South Africa, Chile, southern Australia, and the Mediterranean

Tropical Forests,forests generally occur in frost-free regions between the tropics of Cancer and Capricorn, in areas of relatively high precipitation. Holdridge’s life zones system (Holdridge 1967), which is a commonly used vegetation classification protocol, distinguishes numerous kinds of tropical forests based on

Lakes,to that goal, much of the chapter will be devoted to an examination of the responses of lake biodiversity to past and ongoing global changes. Related reviews have emphasized the response of freshwaters to changes in climate alone (Carpenter et al. 1992; Firth and Fisher 1992; Arnell et al. 1996; Cus

Their value derives, to some degree, from their biological diversity, including genetic, species, and community diversity (Angermeier and Schlosser 1995). Of the many components of biodiversity, species diversity is the best documented and provides the focus for this chapter.

The first step was to identify the major drivers of biodiversity change at the global scale: changes in land use, climate,
