The Biology Of African Savannahs

Savannah habitats comprise an ecologically important, but ultimately fragile, ecosystem. They constitute one of the largest biomes on Earth, covering almost 20% of the land surface, and can be simply described as tropical and subtropical grasslands with scattered bushes and trees. Most savannahs occur in Africa, although smaller areas can be found in South America, India, and Australia. They form a rich mosaic of diverse ecosystems, and this book offers a concise but comprehensive introduction to their ecology, biodiversity, and conservation. The Biology of African Savannahs describes the major plants (grasses, and trees such as Acacia) and animals (mainly large mammals) that live in this habitat, and examines the biological and ecological factors that influence their population size, interactions (such as predation), and community composition. Conservation issues such as climate change, hunting, and conflict between wildlife and domestic animals are also discussed. This new edition has been updated throughout with the latest research in the field, and contains new technique boxes which introduce readers to some of the analytical methods used to study African savannahs. This accessible text is suitable for both senior undergraduate and graduate students taking courses in savannah and tropical ecology as part of a wider ecology and/or conservation biology degree programme. It will also be of relevance and use to the many professional ecologists and conservation practitioners requiring a concise but authoritative overview of the topic.

This book tells the sweeping story of the role that East African savannas played in human evolution, how people, livestock, and wildlife interact in the region today, and how these relationships might shift as the climate warms, the world globalizes, and human populations grow. Our ancient human ancestors were nurtured by African savannas, which today support pastoral peoples and the last remnants of great Pleistocene herds of large mammals. Why has this wildlife thrived best where they live side-by-side with humans? Ecologist Robin S. Reid delves into the evidence to find that herding is often compatible with wildlife, and that pastoral land use sometimes enriches savanna landscapes and encourages biodiversity. Her balanced, scientific, and accessible examination of the current state of the relationships among the region’s wildlife and people holds critical lessons for the future of conservation around the world.

Introductory textbook using the entire range of tropical ecosystems - terrestrial, freshwater and marine - to illustrate and explain major ecological concepts.

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.

Insights on current research and recent developments in understanding global savanna systems Increasingly recognized as synonymous with tropical grassy biomes, savannas are found in tropical and sub-tropical climates as well as warm, temperate regions of North America. Savanna Woody Plants and Large Herbivores examines the interactions between woody plants and browsing mammals in global savannas—focusing primarily on the C4 grassy ecosystems with woody components that constitute the majority of global savannas—and discusses contemporary savanna management models and applications. This much-needed addition to current research examines topics including the varying behavior of browsing mammals, the response to browsing by woody species, and the factors that inhibit forage intake. Contributions from an international team of active researchers and experts compare and contrast different savanna ecosystems, offering a global perspective on savanna functioning, the roles of soil and climate in resource availability and organism interaction, and the possible impacts of climate change across global savannas. Fills a gap in literature on savanna management issues, including biodiversity conservation and animal production Applies concepts developed in other biomes to future savanna research Complements contemporary books on savanna or large herbivore ecology Focuses on the woody component of savanna ecosystems and large herbivore interactions in savannas Compares tree-mammal systems of savannas and other eco-systems of temperate and boreal regions Provides numerous case studies of plant-mammal interactions from various savanna ecosystems Savanna Woody Plants and Large Herbivores is a valuable addition to those in fields such as ecology, wildlife and conservation biology, natural resource management, and environmental science.

An ordered and scientific study of the ecology of all African carnivores larger than jackals. Numerous colour photographs taken by both authors, and excellent sketches by the internationally renowned wildlife artist Clive Walker, depict the life and habitat of these carnivores.

This book develops a unified vision of the ecology of dry savannas, a little studied ecosystem.

"Ultimately, we can all trace our origins back to the savannas of Africa. Robin Reid's book provides an eloquent introduction into the biology of the savannas that shaped us as humans; simultaneously, she provides an insightful and comprehensive overview of current and future threats to East African savannas and the steps that need to be taken to conserve the world we first lived in. Don't go to East Africa without first reading this book; it will enhance your safari and empower your research."–Andrew P. Dobson, author of Conservation and Biodiversity "Savannas of Our Birth provides a balanced, scientific, and accessible examination of the current state of East African savannas and the relationships among the wildlife and people who live there. Reid examines how savannas came to be and what alternative futures may be possible by trying to chart a middle ground in contentious debates about conservation and local rights."–J. Terrence McCabe, author of Cattle Bring Us to Our Enemies: Turkana Ecology, History, and Raiding in a Disequilibrium System "Reid's research focusing on pastoralists has reminded me that wildlife and domestic livestock co-existed to their mutual benefit for the last 2000 years. With reopened eyes, I've even seen it for myself in the case of the Masai and the savanna wildlife I study. There is an extraordinary wealth of information in this book."–Richard D. Estes, author of The Behavior Guide to African Mammals
