This book was released on 1993-08-15 with total page 583 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inbreeding, the mating of close kin, and outbreeding, the mating of distant relatives or unrelated organisms, have long been important subjects to evolutionary biologists. Inbreeding reduces genetic diversity in a population, increasing the likelihood that genetic defects will become widespread and deprive a population of the diversity it may need to cope with its environment. Most plants and animals have evolved behavioral and morphological mechanisms to avoid inbreeding. However, today many endangered species exist only in small, very isolated populations where inbreeding is unavoidable, so it has become a concern for conservationists. In this volume, twenty-six experts in evolution, behavior, and genetics examine the causes and consequences of inbreeding. The authors ask whether inbreeding is as problematic as biologists have thought, under what ecological conditions inbreeding occurs, and whether organisms that inbreed have mechanisms to dampen the anticipated problems of reduced genetic variation. The studies, including theoretical and empirical work on wild and captive populations, demonstrate that many plants and animals inbreed to a greater extent than biologists have thought, with variable effects on individual fitness. Graduate students and researchers in evolutionary biology, animal behavior, ecology, and conservation biology will welcome this wide-ranging collection.

Download or read book The Human Tide written by Paul Morland and published by PublicAffairs. This book was released on 2019-03-05 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: A dazzling new history of the irrepressible demographic changes and mass migrations that have made and unmade nations, continents, and empires The rise and fall of the British Empire; the emergence of America as a superpower; the ebb and flow of global challenges from Nazi Germany, Imperial Japan, and Soviet Russia. These are the headlines of history, but they cannot be properly grasped without understanding the role that population has played. The Human Tide shows how periods of rapid population transition -- a phenomenon that first emerged in the British Isles but gradually spread across the globe--shaped the course of world history. Demography -- the study of population -- is the key to unlocking an understanding of the world we live in and how we got here. Demographic changes explain why the Arab Spring came and went, how China rose so meteorically, and why Britain voted for Brexit and America for Donald Trump. Sweeping from Europe to the Americas, China, East Asia, the Middle East, and North Africa, The Human Tide is a panoramic view of the sheer power of numbers.

Download or read book A Pivotal Moment written by Laurie Ann Mazur and published by Island Press. This book was released on 2012-09-26 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: With contributions by leading demographers, environmentalists, and reproductive health advocates, A Pivotal Moment offers a new perspective on the complex connection between population dynamics and environmental quality. It presents the latest research on the relationship between population growth and climate change, ecosystem health, and other environmental issues. It surveys the new demographic landscape—in which population growth rates have fallen, but human numbers continue to increase. It looks back at the lessons of the last half century while looking forward to population policies that are sustainable and just. A Pivotal Moment embraces the concept of “population justice,” which holds that inequality is a root cause of both rapid population growth and environmental degradation. By addressing inequality—both gender and economic—we can reduce growth rates and build a sustainable future.
Download or read book A Short History of Mathematical Population Dynamics written by Nicolas Bacaër and published by Springer Science & Business Media. This book was released on 2011-02-01 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: As Eugene Wigner stressed, mathematics has proven unreasonably effective in the physical sciences and their technological applications. The role of mathematics in the biological, medical and social sciences has been much more modest but has recently grown thanks to the simulation capacity offered by modern computers. This book traces the history of population dynamics---a theoretical subject closely connected to genetics, ecology, epidemiology and demography---where mathematics has brought significant insights. It presents an overview of the genesis of several important themes: exponential growth, from Euler and Malthus to the Chinese one-child policy; the development of stochastic models, from Mendel's laws and the question of extinction of family names to percolation theory for the spread of epidemics, and chaotic populations, where determinism and randomness intertwine. The reader of this book will see, from a different perspective, the problems that scientists face when governments ask for reliable predictions to help control epidemics (AIDS, SARS, swine flu), manage renewable resources (fishing quotas, spread of genetically modified organisms) or anticipate demographic evolutions such as aging.

Available in PDF, EPUB and Kindle. Book excerpt: October 31, 2011, marked an uneasy milestone for Planet Earth. On this day, the global population surpassed seven billion. What does that mean for a world that, until the nineteenth century, was home to less than one billion people? Experts say it means the planet is in trouble. Some wonder if Earth will even be able to sustain human life at its current rate of growth. Will there be enough food for everyone? Will conflicts over land increase? How will the environment be affected? Can humanity survive the predicted disasters? More than a simple case of running out of space, the population crisis is interwoven with a host of other issues?from climate change and resource management to war, disease, and poverty. Discover how all these factors converge to place an entire planet in crisis mode?and explore what sort of responses that crisis may require.
Download or read book Fatal Misconception written by Matthew Connelly and published by Harvard University Press. This book was released on 2010-03-30 with total page 538 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fatal Misconception is the disturbing story of our quest to remake humanity by policing national borders and breeding better people. As the population of the world doubled once, and then again, well-meaning people concluded that only population control could preserve the “quality of life.” This movement eventually spanned the globe and carried out a series of astonishing experiments, from banning Asian immigration to paying poor people to be sterilized. Supported by affluent countries, foundations, and non-governmental organizations, the population control movement experimented with ways to limit population growth. But it had to contend with the Catholic Church’s ban on contraception and nationalist leaders who warned of “race suicide.” The ensuing struggle caused untold suffering for those caught in the middle—particularly women and children. It culminated in the horrors of sterilization camps in India and the one-child policy in China. Matthew Connelly offers the first global history of a movement that changed how people regard their children and ultimately the face of humankind. It was the most ambitious social engineering project of the twentieth century, one that continues to alarm the global community. Though promoted as a way to lift people out of poverty—perhaps even to save the earth—family planning became a means to plan other people‘s families. With its transnational scope and exhaustive research into such archives as Planned Parenthood and the newly opened Vatican Secret Archives, Connelly’s withering critique uncovers the cost inflicted by a humanitarian movement gone terribly awry and urges renewed commitment to the reproductive rights of all people.
Download or read book Global Population written by Alison Bashford and published by Columbia University Press. This book was released on 2014-02-11 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concern about the size of the world’s population did not begin with the Baby Boomers. Overpopulation as a conceptual problem originated after World War I and was understood as an issue with far-reaching ecological, agricultural, economic, and geopolitical consequences. This study traces the idea of a world population problem as it developed from the 1920s through the 1950s, long before the late-1960s notion of a postwar “population bomb.” Drawing on international conference transcripts, the volume reconstructs the twentieth-century discourse on population as an international issue concerned with migration, colonial expansion, sovereignty, and globalization. It connects the genealogy of population discourse to the rise of economically and demographically defined global regions, the characterization of “civilizations” with different standards of living, global attitudes toward “development,” and first- and third-world designations.

This book was released on 2003-02-01 with total page 536 pages. Available in PDF, EPUB and Kindle. Book excerpt: The anthrax incidents following the 9/11 terrorist attacks put the spotlight on the nation's public health agencies, placing it under an unprecedented scrutiny that added new dimensions to the complex issues considered in this report. The Future of the Public's Health in the 21st Century reaffirms the vision of Healthy People 2010, and outlines a systems approach to assuring the nation's health in practice, research, and policy. This approach focuses on joining the unique resources and perspectives of diverse sectors and entities and challenges these groups to work in a concerted, strategic way to promote and protect the public's health. Focusing on diverse partnerships as the framework for public health, the book discusses: The need for a shift from an individual to a population-based approach in practice, research, policy, and community engagement. The status of the governmental public health infrastructure and what needs to be improved, including its interface with the health care delivery system. The roles nongovernment actors, such as academia, business, local communities and the media can play in creating a healthy nation. Providing an accessible analysis, this book will be important to public health policy-makers and practitioners, business and community leaders, health advocates, educators and journalists.
Download or read book An Essay on the Principle of Population and Other Writings written by Thomas Malthus and published by Penguin UK. This book was released on 2015-06-04 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Malthus' life's work on human population and its dependency on food production and the environment was highly controversial on publication in 1798. He predicted what is known as the Malthusian catastrophe, in which humans would disregard the limits of natural resources and the world would be plagued by famine and disease. He significantly influenced the thinking of Darwin and Alfred Russel Wallace and his theories continue to raise important questions today in the fields of social theory, economics and the environment. With an introduction by Robert Mayhew.
Download or read book Plague and Empire in the Early Modern Mediterranean World written by Nükhet Varlik and published by Cambridge University Press. This book was released on 2015-07-22 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first systematic scholarly study of the Ottoman experience of plague during the Black Death pandemic and the centuries that followed. Using a wealth of archival and narrative sources, including medical treatises, hagiographies, and travelers' accounts, as well as recent scientific research, Nükhet Varlik demonstrates how plague interacted with the environmental, social, and political structures of the Ottoman Empire from the late medieval through the early modern era. The book argues that the empire's growth transformed the epidemiological patterns of plague by bringing diverse ecological zones into interaction and by intensifying the mobilities of exchange among both human and non-human agents. Varlik maintains that persistent plagues elicited new forms of cultural imagination and expression, as well as a new body of knowledge about the disease. In turn, this new consciousness sharpened the Ottoman administrative response to the plague, while contributing to the makings of an early modern state.

Download or read book Empty Planet written by Darrell Bricker and published by Signal. This book was released on 2019-02-05 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the authors of the bestselling The Big Shift, a provocative argument that the global population will soon begin to decline, dramatically reshaping the social, political, and economic landscape. For half a century, statisticians, pundits, and politicians have warned that a burgeoning planetary population will soon overwhelm the earth's resources. But a growing number of experts are sounding a different kind of alarm. Rather than growing exponentially, they argue, the global population is headed for a steep decline. Throughout history, depopulation was the product of catastrophe: ice ages, plagues, the collapse of civilizations. This time, however, we're thinning ourselves deliberately, by choosing to have fewer babies than we need to replace ourselves. In much of the developed and developing world, that decline is already underway, as urbanization, women's empowerment, and waning religiosity lead to smaller and smaller families. In Empty Planet, Ibbitson and Bricker travel from South Florida to Sao Paulo, Seoul to Nairobi, Brussels to Delhi to Beijing, drawing on a wealth of research and firsthand reporting to illustrate the dramatic consequences of this population decline--and to show us why the rest of the developing world will soon join in. They find that a smaller global population will bring with it a number of benefits: fewer workers will command higher wages; good jobs will prompt innovation; the environment will improve; the risk of famine will wane; and falling birthrates in the developing world will bring greater affluence and autonomy for women. But enormous disruption lies ahead, too. We can already see the effects in Europe and parts of Asia, as aging populations and worker shortages weaken the economy and impose crippling demands on healthcare and social security. The United States is well-positioned to successfully navigate these coming demographic shifts--that is, unless growing isolationism and anti-immigrant backlash lead us to close ourselves off just as openness becomes more critical to our survival than ever before. Rigorously researched and deeply compelling, Empty Planet offers a vision of a future that we can no longer prevent--but one that we can shape, if we choose.
