Checkerspot butterflies have been used as an extraordinarily successful model system for more than four decades. This volume presents the first synthesis of the broad range of studies of that system as conducted in Ehrlich's research group in Stanford, in Hanski's research group in Helsinki and elsewhere. Ehrlich's long - term research project on Edith's checkerspot helped establish an intergrated disipline of population biology in the 1960s and ever since has contributed many fundamental insights into the ecological and evolutionary dynamics of populations. Hanski's and his associates' work an the Glanville fritillary for the past 14 years has been instrumental in establishing the field of metapopulation biology and showing how theoretical and empirical work can be effectively combined in the same project.

Conservation Biology for All provides cutting-edge but basic conservation science to a global readership. A series of authoritative chapters have been written by the top names in conservation biology with the principal aim of disseminating cutting-edge conservation knowledge as widely as possible. Important topics such as balancing conversion and human needs, climate change, conservation planning, designing and analyzing conservation research, ecosystem services, endangered species management, extinctions, fire, habitat loss, and invasive species are covered. Numerous textboxes describing additional relevant material or case studies are also included. The global biodiversity crisis is now unstoppable; what can be saved in the developing world will require an educated constituency in both the developing and developed world. Habitat loss is particularly acute in developing countries, which is of special concern because it tends to be these locations where the greatest species diversity and richest centres of endemism are to be found. Sadly, developing world conservation scientists have found it difficult to access an authoritative textbook, which is particularly ironic since it is these countries where the potential benefits of knowledge application are greatest. There is now an urgent need to educate the next generation of scientists in developing countries, so that they are in a better position to protect their natural resources.

Though separated by thousands of miles, the United States and Australia have much in common. Geographically both countries are expansive-the United States is the fourth largest in land mass and Australia the sixth-and both possess a vast amount of natural biodiversity. At the same time, both nations are on a crash course toward environmental destruction. Highly developed super consumers with enormous energy footprints and high rates of greenhouse-gas emissions, they are two of the biggest drivers of climate change per capita. As renowned ecologists Corey J. A. Bradshaw and Paul R. Ehrlich make clear in Killing the Koala and Poisoning the Prairie, both of these countries must confront the urgent question of how to stem this devastation and turn back from the brink. In this book, Bradshaw and Ehrlich provide a spirited exploration of the ways in which the United States and Australia can learn from their shared problems and combine their most successful solutions in order to find and develop new resources, lower energy consumption and waste, and grapple with the dynamic effects of climate change.Peppering the book with humor, irreverence, and extensive scientific knowledge, the authors examine how residents of both countries have irrevocably altered their natural environments, detailing the most pressing ecological issues of our time, including the continuing resource depletion caused by overpopulation. They then turn their discussion to the politics behind the failures of environmental policies in both nations and offer a blueprint for what must be dramatically changed to prevent worsening the environmental crisis. Although focused on two nations, Killing the Koala and Poisoning the Prairie clearly has global implications-the problems facing the United States and Australia are not theirs alone, and the solutions to come will benefit by being crafted in coalition. This book provides a vital opportunity to learn from both countries' leading environmental thinkers and to heed their call for a way forward together.

In this provocative book, the authors look at the interaction between population and food supply and offer a powerful and radical strategy for balancing human numbers with nutritional needs. Their proposals include improving the status of women, reducing racism and religious prejudice, reforming the agricultural system, and shrinking the growing gap between rich and poor.“This ambitious, enlightened handbook is a cornucopia of strategies and ideas for concerned citizens and policymakers.”—Publishers Weekly“Give equal education and power to women throughout the world, argue the authors: when that happens, birth rates fall and food supplies go up.”—San Francisco Chronicle (Best Bets of 1995)“[The book] can help us understand the past and possible future of the meals most Westerners take for granted.”—Bill McKibben, New York Review of Books“A well-reasoned account of how poverty forces unsustainable use of natural resources . . . a careful and balanced treatment of developments in agriculture . . . that may help food production to stay ahead of population growth.”—Basia Zaba, Nature“This generation faces a set of challenges unprecedented in their scope and severity and in the shortness of time left to resolve them. . . . The Stork and the Plow sets these out thoughtfully [and] accurately. . . . We can all hope this urgent message is carefully heeded.”—Henry W. Kendall, Nobel laureate and Julius A. Stratton Professor of Physics, MIT“A wonderful piece of work.”—Partha Dasgupta, American Scientist

We live on an unexplored planet, ignorant of more than eighty percent of the species that share our world. In this fascinating and abundantly illustrated book, two eminent ecologists discuss the biological diversity of the Earth, showing how the natural systems that surround us play an essential role in protecting our basic life-support systems.Andrew Beattie and Paul Ehrlich tell us about the millions of species providing ecosystem services that maintain the quality of our air and water and the fertility of the soil, dispose of domestic, industrial, and agricultural waste, and protect crops from pests. The authors also describe how biological diversity opens the way for new medicines, pharmaceuticals, construction materials and designs, and manufactured goods. They point to innovative industries that harness species for the biological repair of damaged landscapes, biological mining, biological pest control, and biomonitoring of the environment. The organisms upon which these activities are founded—although often microscopic, obscure, or bizarre—provide natural capital that is worth infinitely more than anyone has previously guessed. The authors urge us to protect the biological wealth of our Earth and keep it from being destroyed by human activity.

A renowned scientist and environmental advocate looks back on a life that has straddled the worlds of science and politics  “Compelling. . . . [Ehrlich’s] memoir includes remarkable stories of his research, travels, friends, colleagues, and scientific controversies that still roil today.”—Peter Gleick, Science  Acclaimed as a public scientist and as a spokesperson on pressing environmental and equity issues, delivering his message from the classroom to 60 Minutes, Paul R. Ehrlich reflects on his life, including his love affair with his wife, Anne, his scientific research, his public advocacy, and his concern for global issues. Interweaving the range of his experiences—as an airplane pilot, a desegregationist, a proud parent—Ehrlich’s insights are priceless on pressing issues such as biodiversity loss, overpopulation, depletion of resources, and deterioration of the environment. A lifelong advocate for women’s reproductive rights, Ehrlich also helped to debunk scientific bias associating skin color and intelligence and warned some fifty years ago about a possible pandemic and the likely ecological consequences of a nuclear war.  This book is a vital contribution to literature focused on the human predicament, including problems of governance and democracy in the twenty-first century, and insight into the ecological and evolutionary science of our day. It is a must-read for anyone interested in understanding global change, our planet’s wonders, and a scientific approach to the present existential threats to civilization.

The Cold and the Dark is the record of the Conference on the Long-Term Worldwide Biological Consequences of Nuclear War, held in Washington, D.C., on October 31 to November 1, 1983. The conference involved over 200 scientists from many nations and drew together the best available scientific information. Its central finding was the phenomenon of nuclear winter: a much more profound and long-lasting devastation of the earth and atmosphere than had been believed possible before. In the two principal papers, Carl Sagan presents the atmospheric and climatic consequences of nuclear war and Paul Ehrlich summarizes its biological implications. Also included is the text of the “Moscow Link” —a dialogue between Soviet and American scientists on nuclear winter—and the technical papers providing the scientific evidence for the book’s conclusions.

Legendary conservationists show us that we still have the power to prevent critical consequences of the sixth extinction in this game-changing book.Can we save threatened animals and ecosystems in the midst of a mass extinction? The answer is a resounding yes! Before They Vanish shows us how. In this wise and impassioned book, renowned conservation scientists Paul R. Ehrlich, Gerardo Ceballos, and Rodolfo Dirzo urge us to shift our thinking rather than succumb to grief over the losses that humanity faces. This comprehensive look at a crucial but often overlooked aspect of conservation—population extinction, or the loss of a species within a specific geographic location—guides us onto a new, hopeful path. The authors argue that conservationists have placed too much emphasis on the extinction of entire species, which occurs gradually enough that we only detect it in the direst of cases. By that time, meaningful action may be impossible. By shifting our focus to identifying extinction threats at the more localized population level, we can intervene more rapidly and effectively to prevent broader declines before it's too late. This change in perspective represents a critical step in saving these vanishing species; early detection and intervention may be our last, best hope for stemming the tide of this global crisis. Using examples from the worlds of vertebrates, invertebrates, plants, fungi, and microorganisms, the authors explain the concept of population extinction, its causes and consequences, and how to prevent the mass destruction of the amazing and unique creatures with whom we share our planet. This call to action is a must-read for anyone concerned with saving endangered and threatened species, our natural world—and ourselves.

When we think of family, we most often think of our sisters and brothers, our cousins and grandparents, rather than our world family or even our community connections. We still identify with our differences more than our similarities, unless it's convenient to do otherwise. Here, two seasoned authors tackle the question of family and what it means to us now and how it might change to help us address the problems that affect us all. Using specific examples throughout the work, they present a unique approach to what it means to belong to one human family. Beginning with a consideration of how the family unit has begun to be defined by allegiances, by common ties and empathy, the authors then discuss the evolution of the family unit and how the "us" vs. "them" mentality gave way to a way of life that separated peoples rather than brought them together. They consider family values, how they arose, developed, were perverted or perfected to suit the family unit's needs, and the confusion that followed. Humanity on a Tightrope focuses on what families and family values are, and how they often create an "us versus them" mentality that is at the root of many of today's most crucial problems from terrorism, racism, and war to the failure of humanity to come to grips with potentially lethal global environmental problems. The book underlines a basic element for solving the human predicament — quickly spreading the domain of empathy. It takes a close look at how we can do that, building on the findings of both social and natural science and using tools ranging from brain imaging to the internet. It explains how civilization is unlikely to persist unless many more people learn to put themselves in the shoes of others to keep society balancing on the tightrope to sustainability - a tightrope suspended over the collapse of civilization.

There's a silent epidemic in western civilization, and it is right under our noses. Our jaws are getting smaller and our teeth crooked and crowded, creating not only aesthetic challenges but also difficulties with breathing. Modern orthodontics has persuaded us that braces and oral devices can correct these problems. While teeth can certainly be straightened, what about the underlying causes of this rapid shift in oral evolution and the health risks posed by obstructed airways?Sandra Kahn and Paul R. Ehrlich, a pioneering orthodontist and a world-renowned evolutionist, respectively, present the biological, dietary, and cultural changes that have driven us toward this major health challenge. They propose simple adjustments that can alleviate this developing crisis, as well as a major alternative to orthodontics that promises more significant long-term relief. Jaws will change your life. Every parent should read this book.
