The aim of this text is to provide an up-to-date understanding of the Serengeti-Mara ecosystem in East Africa, home to one of the largest and most diverse populations of animals in the world. Building on the groundwork laid by "Serengeti: Dynamics of an Ecosystem", published in 1979 by the University of Chicago Press, this work integrates studies of the ecosystem at every level, from the plants at the bottom of the visible food chain to the many species of herbivores and predators, as well as the system as a whole. Drawing on data from long-term studies, the contributors examine the processes that have produced the Serengeti's biological diversity, with its species-species and species-environment interactions. The book also discusses computer modelling as a tool for exploring these interactions, employing it to test and anticipate the effects of social, political and economic changes on the entire ecosystem and on particular species, with the aim of assisting the development of future conservation and management strategies.
