Places the scientific and management experience in Kruger within the framework of modern ecological theory and its practical applications. The book uses a cross-cutting theme of ecological heterogeneity - the idea that ecological systems function across a full hierarchy of physical and biological components, processes, and scales, in a dynamic space-time mosaic. Contributors, who include many distinguished ecologists who have worked in Kruger in recent years, examine a range of topics covering broad taxonomic groupings and ecological processes.
