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.

"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""

Peatlands form important landscape elements in many parts of the world and play significant roles for biodiversity and global carbon balance. This new edition has been fully revised and updated, documenting the latest advances in areas such as microbial processes and relations between biological processes and hydrology. As well as thoroughly referencing the latest research, the authors expose a rich older literature where an immense repository of natural history has accumulated. The Biology of Peatlands starts with an overview of the main peatland types (marsh, swamp, fen, and bog), before examining the entire range of biota present (microbes, invertebrates, plants, and vertebrates), together with their specific adaptations to peatland habitats. Detailed coverage is devoted to the genus Sphagnum, the most important functional plant group in northern peatlands, although tropical and southern hemisphere peatlands are also covered. Throughout the book the interactions between organisms and environmental conditions (especially wetness, availability of oxygen, and pH) are emphasized, with chapters on the physical and chemical characteristics of peat, the role of peat as an archive of past vegetation and climate, and peatland succession and development. Several other key factors and processes are then examined, including hydrology and nutrient cycling. The fascinating peatland landforms in different parts of the world are described, together with theories on how they have developed. Human interactions with peatlands are considered in terms of management, conservation, and restoration. A final chapter, new to this edition, focuses on the role of peatlands as sources or sinks for the greenhouse gases carbon dioxide and methane, and the influences of climate change on peatlands. This timely and accessible text is suitable for students and researchers of peatland ecology, as well as providing an authoritative overview for professional ecologists and conservation biologists.

This volume presents new theoretical approaches, methodologies, subject pools, and topics in the field of environmental anthropology. Environmental anthropologists are increasingly focusing on self-reflection - not just on themselves and their impacts on environmental research, but also on the reflexive qualities of their subjects, and the extent to which these individuals are questioning their own environmental behavior. Here, contributors confront the very notion of "natural resources" in granting non-human species their subjectivity and arguing for deeper understanding of "nature," and "wilderness" beyond the label of "ecosystem services." By engaging in interdisciplinary efforts, these anthropologists present new ways for their colleagues, subjects, peers and communities to understand the causes of, and alternatives to environmental destruction. This book demonstrates that environmental anthropology has moved beyond the construction of rural, small group theory, entering into a mode of solution-based methodologies and interdisciplinary theories for understanding human-environmental interactions. It is focused on post-rural existence, health and environmental risk assessment, on the realm of alternative actions, and emphasizes the necessary steps towards preventing environmental crisis.

Scholars and policymakers alike agree that innovation in the biosciences is key to future growth. The field continues to shift and expand, and it is certainly changing the way people live their lives in a variety of ways. With a large share of federal research dollars devoted to the biosciences, the field is just beginning to live up to its billing as a source of innovation, economic productivity and growth. Vast untapped potential to imagine and innovate exists in the biosciences given new tools now widely available. In The Biologist's Imagination, William Hoffman and Leo Furcht examine the history of innovation in the biosciences, tracing technological innovation from the late eighteenth century to the present and placing special emphasis on how and where technology evolves. Place is often key to innovation, from the early industrial age to the rise of the biotechnology industry in the second half of the twentieth century. The book uses the distinct history of bioinnovation to discuss current trends as they relate to medicine, agriculture, energy, industry, ecosystems, and climate. Fast-moving research fields like genomics, synthetic biology, stem cell research, neuroscience, bioautomation and bioprinting are accelerating these trends. Hoffman and Furcht argue that our system of bioscience innovation is itself in need of innovation. It needs to adapt to the massive changes brought about by converging technologies and the globalization of higher education, workforce skills, and entrepreneurship. The Biologist's Imagination is both a review of past models for bioscience innovation and a forward-looking, original argument for what future models should take into account.

What are the impacts of population growth? Can our planet support the demands of the ten billion people anticipated to be the world's population by the middle of this century? While it is common to hear about the problems of overpopulation, might there be unexplored benefits of increasing numbers of people in the world? How can we both consider and harness the potential benefits brought by a healthier, wealthier and larger population? May more people mean more scientists to discover how our world works, more inventors and thinkers to help solve the world's problems, more skilled people to put these ideas into practice? In this book, leading academics with a wide range of expertise in demography, philosophy, biology, climate science, economics and environmental sustainability explore the contexts, costs and benefits of a burgeoning population on our economic, social and environmental systems.

In a lively, personal style, Savannah Lives offers an introduction to the African savannahs as home to a unique wildlife and as the context for the origin and evolution of the human species. After briefly explaining the geology of the African continent and the climatic changes that have shapedits vegetation, Staffan Ulfstrand describes how the savannah is constantly modified by fire, water, elephants - and people. Much of the book is taken up with describing the lives of some of the most charismatic savannah species and how they have evolved to cope with the environment they lived in.Ulfstrand goes on to explain how our knowledge of animals' behaviour and evolution can provide insights into much of our behaviour and modern life-style. The book is written for everyone who is interested in the natural history of savannahs, in their animal inhabitants, and in the human species.Most of all, it will appeal to anyone who has visited or hopes to visit the fabulous scenery and spectacular animal diversity of Africa's savannahs.

East Africa is one of the most diverse and interesting tropical area on the planet. It is home not only to the last great megafaunal assemblage, but also to human populations with the highest growth rates. This book draws on the expertise of leading ecologists, each intimately familiar with a particular set of East African ecosystems, to provide the first in-depth and integrated account of the ecology, management, threats, and conservation of these diverse ecosystems. Summarizing the tremendous wealth of scientific research that has come out of East Africa in the last few decades, each chapter analyzes a given ecosystem type, taking the reader through the basics of its ecology, its historical use (and misuse) by humans, and its prospects for conservation. Throughout the book, linkages and similarities among ecosystems are emphasized, the historical and contemporary role of humans in shaping these ecosystems is considered, fundamental principles of ecology are considered, and interesting case studies are highlighted. Students and researchers in ecology, conservation biology, and environmental sciences will find this book useful in their work.

There is now an increased awareness of the importance of polar regions in the Earth system, as well as their vulnerability to anthropogenic derived change, including of course global climate change. This new edition offers a concise but comprehensive introduction to polar ecology and has been thoroughly revised and updated throughout, providing expanded coverage of marine ecosystems and the impact of humans. It incorporates a detailed comparison of the Arctic and Antarctic systems, with a particular emphasis on the effects of climate change, and describes marine, freshwater, glacial, and terrestrial habitats. This breadth of coverage is unique in the polar biology literature. As with other titles in the Biology of Habitats Series, particular emphasis is placed on the organisms that dominate these extreme environments although pollution, conservation and experimental aspects are also considered. This accessible text is suitable for both senior undergraduate and graduate students taking courses in polar ecology, often as part of a wider marine biology degree programme. It will also be of value and use to the many professional ecologists and conservation biologists requiring a concise overview of the topic.

As atmospheric concentrations of greenhouse gases continue to increase, so does the potential for atmospheric warming and associated climate change. In an effort to address the threat of global climate change, 155 countries signed the UN Framework Convention on Climate Change at the Earth Summit in Rio de Janeiro in June 1992. As of the first session of the Conference of the Parties, 128 nations had ratified the Convention. Among their other commitments, Parties to the Convention must develop and periodically update national inventories of net anthropogenic greenhouse gas emissions using comparable methodologies, and must develop and implement national programs to mitigate greenhouse gas emissions. To further the development of emission inventories and mitigation options within the African context, 64 governmental and non-governmental scientists and policy analysts from 23 nations gathered at a workshop near Johannesburg, South Africa from 29 May to 2 June 1995. The workshop focused on forestry, land-use change, and agriculture, because these sectors not only are responsible for the majority of emissions from the continent and provide promising opportunities for emissions mitigation, but also are a vital component of African economic growth and development. This book presents the workshop's major conclusions and findings, as well as individual papers that were prepared for the workshop, each of which was peer-reviewed and accepted for publication as part of the workshop process. The papers cover four areas: (1) issues are associated with data collection and emission factor determination; (2) problems associated with applying the IPCC inventory methodologies in Africa; (3) results of national inventory assessments in Africa; and (4) possible emissions mitigation options and methods for evaluating their potential viability. As the first book dedicated solely to greenhouse gas emissions and mitigation options in Africa, this will be an invaluable resource to scientists, policymakers, and development specialists interested in global climate change and Africa.

Although most antelope species still exist in large numbers in sub-Saharan Africa (some in hundreds of thousands), up to three-quarters of the species are in decline. Threats to their survival arise from the rapid growth of human and livestock populations, with consequent degradation and destruction of natural habitats, and excessive offtake by meat hunters. In addition, some parts of Africa are mow almost completely devoid of large wild animals because of uncontrolled slaughter during recent civil wars. This report presents the information currently held by the IUCN/SSC Antelope Specialist Group on the conservation status of each antelope species (and selected subspecies) in sub-Saharan Africa. Key areas have been identified for the conservation of representative antelope communities. While external donors make the greatest contributions to the conservation of antelopes, greater recognition of wildlife conservation in national and regional development plans is often a critically important requirement.
