Biodiversity and Savanna Ecosystem Processes

Savannas are the most widespread ecosystem in the tropics and as such are subjected to great human pressure that may result in massive soil degradation.
The book addresses the role of species in the function of savanna ecosystems. It is shown that savannas are enormously diverse and that four factors determine the function of savanna ecosystems: Plant Available Moisture; Plant Available Nutrients; Fire; Herbivores.
