Devoted to birds and wildlife since childhood, Mark's early scientific research at Oxford, Aberdeen and the RSPB provided a solid background for his management, ambassadorial, and political lobbying activities which were to follow - and his larger than life, yet quietly humane personality has provided the final tools in his own, unique, nature conservationists' toolbox. In this book, Mark mixes a great many stories from his professional life at the RSPB with personal anecdotes and passionate arguments on past and present issues in bird and nature conservation. He shows us something of the many scientists whose work paves the way for conservation action, places domestic conservation into an international context, takes us behind the scenes to glimpse the politicians who have worked with him, or against him, along the way. Mark leaves us armed with practical tips and a guiding philosophy to take wildlife conservation though the troubled years that lie ahead. A personal, philosophical and political history of 25 years of bird conservation, this book provides an instructive and amusing read for all those who would like a glimpse into the birds and wildlife conservation world - what the issues are, what must be done, how it can be done, and the challenges, highs and lows involved.

Sir Arthur George Tansley (1871 1955) was an English botanist who made significant contributions to the development of ecology and the conservation movement. In this volume, which was first published in 1945, Tansley discusses the ways in which English natural habitats might be preserved in the face of post-war modernisation processes. The book puts forward the thesis that English rural beauty can only be protected through 'the deliberate conservation of much of our native vegetation', a process that must be achieved through a proper understanding of plant ecology. This process, of course, runs in tandem with the aim of protecting the various forms of animal life which find their homes within a diversity of habitats. The text also contains numerous photographic figures and a detailed index. This is a fascinating book that will be of value to anyone with an interest in ecology and botany.

One of the greatest unmet challenges in conservation biology is the genetic management of fragmented populations of threatened animal and plant species. More than a million small, isolated, population fragments of threatened species are likely suffering inbreeding depression and loss of evolutionary potential, resulting in elevated extinction risks. Although these effects can often be reversed by re-establishing gene flow between population fragments, managers very rarely do this. On the contrary, genetic methods are used mainly to document genetic differentiation among populations, with most studies concluding that genetically differentiated populations should be managed separately, thereby isolating them yet further and dooming many to eventual extinction! Many small population fragments are going extinct principally for genetic reasons. Although the rapidly advancing field of molecular genetics is continually providing new tools to measure the extent of population fragmentation and its genetic consequences, adequate guidance on how to use these data for effective conservation is still lacking. This accessible, authoritative text is aimed at senior undergraduate and graduate students interested in conservation biology, conservation genetics, and wildlife management. It will also be of particular relevance to conservation practitioners and natural resource managers, as well as a broader academic audience of conservation biologists and evolutionary ecologists.

Twice declared extinct, North America’s most endangered mammal species, the black-footed ferret (BFF), is making a comeback thanks to an evolving conservation regimen at more than thirty reintroduction sites across the continent. Lawrence Lenhart lingers at one such site in his proverbial backyard, the Aubrey Valley in northern Arizona. He clocks hundreds of hours behind the wheel, rolling over ranch ruts as he shines a spotlight over dusky sage steppe in the hopes of catching a fleck of emerald eyeshine. The beguiling weasel at the center of this book is more than a charismatic minifauna; it is the covert ambassador of a critical ecosystem that has dwindled to 1 percent of its former size. In a landscape menaced by habitat fragmentation, bacterial plague, settler colonialism, and soil death, a ferret must be resilient. Lenhart investigates the human efforts to sustain the species through monitoring, vaccination, captive breeding, and even cloning. Lenhart balances this lens of environmental witness with personal essaying that captures the parallel story of his wife’s pregnancy as he realizes the ferret’s conservation story is dramatically synchronized with her trimesters. In preparing to raise a child in the Anthropocene, Lenhart takes stock of his own ecosystem and finds something is amiss. Through an ethic of "deeper ecology," Lenhart must hone his ecological interest in the black-footed ferret to assure it isn’t overshadowed by his own paternal interests.

Extinction Studies focuses on the entangled ecological and social dimensions of extinction, exploring the ways in which extinction catastrophically interrupts life-giving processes of time, death, and generations. The volume opens up important philosophical questions about our place in, and obligations to, a more-than-human world. Drawing on fieldwork, philosophy, literature, history, and a range of other perspectives, each of the chapters in this book tells a unique extinction story that explores what extinction is, what it means, why it matters-and to whom.

The Amazon Basin's rivers, estuaries and tributaries are home to as many as 1000 species of catfish. In this work, two scientists offer a natural history of the Amazon giant catfish and its central place as a source of food and income within the ecology and economy of the Amazon Basin. While focusing primarily on two species of giant catfish - known locally as Dourada and Piramutaba - the authors also present illustrated accounts of 13 distinct large fish. Their research yields strong statistical data and field observations that illustrate the catfishes' extensive migratory range and presents solid evidence of animal species requiring or using a large part of the basin for their ecological needs. This text also proposes techniques for the careful management of this resource to ensure its survival for future generations. This study should be a useful reference for marine and conservation biologists in the field, ecologists, resource management professionals and development workers.

"Yendegaia National Park" offers a visually spectacular tour of one of Earth's most remote and scenic national parks. In Chilean Patagonia on the grand island of Tierra del Fuego, the new park -- designated in 2014 -- was prompted by a donation of private land to the Chilean park system. When combined with adjacent federal land, the new protected area covers some 372,000 acres, and forms a habitat linkage between existing national parks in Chile and Argentina. Thus the new Yendegaia National Park has helped establish one of the planet's most significant trans-boundary protected areas, or "peace parks." During expeditions to Yendegaia in various seasons, renowned nature photographer Antonio Vizcaino captured the harsh beauty of a remote land at the end of the world where glacier-carved peaks, untamed rivers, windblown steppe, and Earth's southernmost forests combine to create a unique and stunningly beautiful landscape. For both armchair adventurers who dream of Patagonia and intrepid travelers planning a trip to Chile's national parks, "Yendegaia National Park" is a must-have.

From foraging patterns in a single tree to social interactions across a home range, how primates use space is a key question in the field of primate behavioral ecology. Drawing on the latest advances in spatial analysis tools, this book offers practical guidance on applying geographic information systems (GIS) to central questions in primatology. An initial methodological section discusses niche modelling, home range analysis and agent-based modelling, with a focus on remote data collection. Research-based chapters demonstrate how ecologists apply this technology to a suite of topics including: calculating the intensity of use of both range and travel routes, assessing the impacts of logging, mining and hunting, and informing conservation strategies.

Thoroughly researched and finely crafted, After the Grizzly traces the history of endangered species and habitat in California, from the time of the Gold Rush to the present. Peter S. Alagona shows how scientists and conservationists came to view the fates of endangered species as inextricable from ecological conditions and human activities in the places where those species lived. Focusing on the stories of four high-profile endangered species-the California condor, desert tortoise, Delta smelt, and San Joaquin kit fox-Alagona offers an absorbing account of how Americans developed a political system capable of producing and sustaining debates in which imperiled species serve as proxies for broader conflicts about the politics of place. The challenge for conservationists in the twenty-first century, this book claims, will be to redefine habitat conservation beyond protected wildlands to build more diverse and sustainable landscapes.

Waking up to roaring lions near her doorless dung hut; encountering elephants while walking with other women to fetch water from a distant spring; realising that older Himba people saw themselves as part of nature, not as separated from it nor at its apex ... These were just some of the experiences that would change the way Margaret Jacobsohn thought about wildlife conservation – and our modern deficiency in ecological intelligence. So, the Capetonian journalist and environmental writer turned researcher became a Namibian and helped pioneer an African way of doing conservation and tourism.

Famed for its spectacular landscapes and gloriously unclad geology, Namibia is a country that wears its skeleton on the outside, the author says.

Similarly, her story is as gritty and real as Namib sand. The conflicts and mishaps, the triumphs and breakthroughs – what it takes to break paradigms and do decades of community based conservation in remote and inaccessible places, earning some of the top international environmental awards along the way.

A book that will make you think.

For all persons seriously concerned about the destruction of natural environments in the contemporary world, this book presents a comprehensive rationale for preserving wild species and ecosystems. Bryan G. Norton appeals most centrally to "transformative value," the power of human contacts with wild species to transform and uplift the human spirit. Until now species preservationists have found a theoretical basis for their policies in the "demand" value of wild species for fulfilling certain narrowly defined human needs or in controversial and badly understood proposals about the "intrinsic" values of species. This work examines such rationales and diverges from them by pointing to new sources of value for wild species: they have worth because they can transform human values. Because of the central role of biological diversity in environmental concerns, the book also provides a fresh perspective on environmental ethics more generally. Why Preserve Natural Variety? is sponsored by the Center for Philosophy and Public Policy at the University of Maryland, as was The Preservation of Species: The Value of Biological Diversity, which was edited by Professor Norton. Originally published in 1986. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

With up to a quarter of all insect species heading towards extinction over the next few decades, there is now a pressing need to summarize the techniques available for measuring insect diversity in order to develop effective conservation strategies.
Insect Conservation outlines the main methods and techniques available to entomologists, providing a comprehensive synthesis for use by graduate students, researchers and practising conservationists worldwide. Both modern and more 'traditional' methodologies are described, backed up by practical background information and a global range of examples. Many newer techniques are included which have not yet been described in the existing book literature.
This book will be particularly relevant to postgraduate and advanced undergraduate students taking courses in insect ecology, conservation biology and environmental management, as well as established researchers in these fields. It will also be a valuable reference for nature conservation practitioners and professional entomologists worldwide.

The management and conservation of natural populations relies heavily on concepts and results generated from models of population dynamics. Yet this is the first book to present a unified and coherent explanation of the underlying theory. This novel text begins with a consideration of what makes a good state variable, progressing from the simplest models (those with a single variable such as abundance or biomass) to more complex models with other key variables of population structure (including age, size, life history stage, and space). Throughout the book, attention is paid to concepts such as population variability, population stability, population viability/persistence, and harvest yield. Later chapters address specific applications to conservation such as recovery planning for species at risk, fishery management, and the spatial management of marine resources. Population Dynamics for Conservation is suitable for graduate-level students. It will also be valuable to academic and applied researchers in population biology. This overview of population dynamic theory can serve to further their population research, as well as to improve their understanding of population management.

Allee effects are (broadly) defined as a decline in individual fitness at low population size or density. They can result in critical population thresholds below which populations crash to extinction. As such, they are very relevant to many conservation programmes, where scientists and managers are often working with populations that have been reduced to low densities or small numbers. There are a variety of mechanisms that can create Allee effects including mating systems, predation, environmental modification, and social interactions. The abrupt and unpredicted collapses of many exploited populations is just one illustration of the need to bring Allee effects to the forefront of conservation and management strategies.
Allee Effects in Ecology and Conservation provides a concise yet authoritative overview of the topic, collating and integrating a widely dispersed literature from various fields - marine and terrestrial, plant and animal, theoretical and empirical, academic and applied. This accessible text, with its clear and simple explanations of both empirical observations and theoretical predications is particularly suitable for professional and academic ecologists requiring an overview of the state-of-the-art in Allee effect research, as well as for graduate students in population ecology and conservation biology. It will also be of relevance to a wide readership of professionals in conservation and management requiring a concise summary of the topic.

A brilliant writer and gifted "big picture" thinker, David Ehrenfeld is one of America's leading conservation biologists. Becoming Good Ancestors unites in a single, up-to-date framework pieces written over two decades, spanning politics, ecology, and culture, and illuminating the forces in modern society that thwart our efforts to solve today's hard questions about society and the environment.
The book focuses on our present-day retreat from reality, our alienation from nature, our unthinking acceptance of new technology and rejection of the old, the loss of our ability to discriminate between events we can control and those we cannot, the denial of non-economic values, and the decline of local communities. If we are aware of what we are losing and why we are losing it, the author notes, all of these patterns are reversible. Through down-to-earth examples, ranging from a family canoe trip in the wilderness to the novels of Jane Austen to Chinese turtle and tiger farms, Ehrenfeld shows how we can use what we learn to move ourselves and our society towards a more stable, less frantic, and far more satisfying life, a life in which we are no longer compelled to damage ourselves and our environment, in which our children have a future, and in which fewer species are endangered and more rivers run clean. In the final chapter, he offers a dramatic view of the possibilities inherent in a fusion of the best elements of conservatism and liberalism.
Our society has an inherent sense of what is right, says Ehrenfeld, and the creativity and persistence to make good things happen. It is now time to apply our intelligence, guided by our moral judgment, to the very large problems we all face. This book is an important first step.

The two volumes of this handbook provide a comprehensive account of the emerging and vibrant science of the ecological restoration of both habitats and species. Ecological restoration aims to achieve complete structural and functional, self-maintaining biological integrity following disturbance. In practice, any theoretical model is modified by a number of economic, social and ecological constraints. Consequently, material that might be considered as rehabilitation, enhancement, re-construction or re-creation is also included. Principles of Restoration defines the underlying principles of restoration ecology, in relation to manipulations and management of the biological, geophysical and chemical framework. The accompanying volume, Restoration in Practice, provides details of state-of-the-art restoration practice in a range of biomes within terrestrial and aquatic ecosystems. The Handbook of Ecological Restoration will be an invaluable resource to anyone concerned with the restoration, rehabilitation, enhancement or creation of habitats in aquatic or terrestrial systems, throughout the world.

Modern zoos and aquaria are playing an increasingly active and important role in protecting and managing global biodiversity. Many zoos include wildlife conservation in their mission and have started changing the focus of their institutions in order to increase even further the benefits of their activities for in situ wildlife conservation. With these developments, the following searching questions are now being asked: What is the true role of zoos in conservation? How can they contribute more significantly to global conservation efforts? What are the unique attributes of zoos that can be applied in the conservation landscape? And should zoos be doing more? In parallel with this voluntary movement, legal requirements for zoos to support conservation in the wild are also becoming more stringent. This 2007 book defines a conservation vision for zoos and aquaria that will be of interest to those working in zoos, alongside practitioners and researchers in conservation.

Reintroduction of Fish and Wildlife Populations provides a practical step-by-step guide to successfully planning, implementing, and evaluating the re-establishment of animal populations in former habitats or their introduction in new environments. In each chapter, experts in reintroduction biology outline a comprehensive synthesis of core concepts, issues, techniques, and perspectives. This manual and reference supports scientists and managers from fisheries and wildlife professions as they plan reintroductions, initiate releases of individuals, and manage restored populations over time. Covering a broad range of taxonomic groups, ecosystems, and global regions, this edited volume is an essential guide for academics, students, and professionals in natural resource management.

A valuable and unique contribution both to environmental ethics and public policy analysis of the preservation of species question. Norton provides a critical overview of the range of thought on the issue, presents a new and comprehensive rationale for preservation of both species and ecosystems, and addresses policy issues.

As our closest primate relatives, chimpanzees offer tantalizing clues about the behavior of early human ancestors. This book provides a rich and detailed portrait of chimpanzee social life in the wild, synthesizing hundreds of thousands of hours of research at seven long-term field sites. Why are the social lives of males and females so different? Why do groups of males sometimes seek out and kill neighboring individuals? Do chimpanzees cooperate when they hunt monkeys? Is their vocal behaviour like human speech? Are there different chimpanzee 'cultures'? Addressing these questions and more, Adam Arcadi presents a fascinating introduction to the chimpanzee social universe and the challenges we face in trying to save this species from extinction. With extensive notes organized by field site and an appendix describing field methods, this book is indispensable for students, researchers, and anyone else interested in the remarkable and complex world of these intelligent apes.
