Book Description
This book focuses on the links between population dynamics and environment. Demographic changes, e.g. population growth and decline, urbanization and migration are analyzed by researchers from different natural and social sciences, focusing on complex interactions between population dynamics and transformations of water and food supply systems. Empirical case studies in selected regions in Europe, Southeast Asia, the Middle East, and Africa from prehistory to present permit to identify specific problem constellations. Solutions are presented in order to enhance the capability of supply systems to adapt to demographic changes.

Book Description
Using Science to Improve the BLM Wild Horse and Burro Program: A Way Forward reviews the science that underpins the Bureau of Land Management's oversight of free-ranging horses and burros on federal public lands in the western United States, concluding that constructive changes could be implemented. The Wild Horse and Burro Program has not used scientifically rigorous methods to estimate the population sizes of horses and burros, to model the effects of management actions on the animals, or to assess the availability and use of forage on rangelands. Evidence suggests that horse populations are growing by 15 to 20 percent each year, a level that is unsustainable for maintaining healthy horse populations as well as healthy ecosystems. Promising fertility-control methods are available to help limit this population growth, however. In addition, science-based methods exist for improving population estimates, predicting the effects of management practices in order to maintain genetically diverse, healthy populations, and estimating the productivity of rangelands. Greater transparency in how science-based methods are used to inform management decisions may help increase public confidence in the Wild Horse and Burro Program.

Book Description
This book broadens and deepens understanding of a wide range of population-climate change linkages. Incorporating population dynamics into research, policymaking and advocacy around climate change is critical for understanding trajectory of global greenhouse gas emissions, for developing and implementing adaptation plans and thus for global and national efforts to curtail this threat. The papers in this volume provide a substantive and methodological guide to the current state of knowledge on issues such as population growth and size and emissions; population vulnerability and adaptation linked to health, gender disparities and children; migration and urbanization; and the data and analytical needs for the next stages of policy-relevant research.

Book Description
Dr. Timothy Schowalter has succeeded in creating a unique, updated treatment of insect ecology. This revised and expanded text looks at how insects adapt to environmental conditions while maintaining the ability to substantially alter their environment. It covers a range of topics- from individual insects that respond to local changes in the environment and affect resource distribution, to entire insect communities that have the capacity to modify ecosystem conditions.Insect Ecology, Second Edition, synthesizes the latest research in the field and has been produced in full color throughout. It is ideal for students in both entomology and ecology-focused programs.NEW TO THIS EDITION:* New topics such as elemental defense by plants, chaotic models, molecular methods to measure disperson, food web relationships, and more* Expanded sections on plant defenses, insect learning, evolutionary tradeoffs, conservation biology and more* Includes more than 350 new references* More than 40 new full-color figures

Book Description
Over the next 20 years, most low-income countries will, for the first time, become more urban than rural. Understanding demographic trends in the cities of the developing world is critical to those countries - their societies, economies, and environments. The benefits from urbanization cannot be overlooked, but the speed and sheer scale of this transformation presents many challenges. In this uniquely thorough and authoritative volume, 16 of the world's leading scholars on urban population and development have worked together to produce the most comprehensive and detailed analysis of the changes taking place in cities and their implications and impacts. They focus on population dynamics, social and economic differentiation, fertility and reproductive health, mortality and morbidity, labor force, and urban governance. As many national governments decentralize and devolve their functions, the nature of urban management and governance is undergoing fundamental transformation, with programs in poverty alleviation, health, education, and public services increasingly being deposited in the hands of untested municipal and regional governments. Cities Transformed identifies a new class of policy maker emerging to take up the growing responsibilities. Drawing from a wide variety of data sources, many of them previously inaccessible, this essential text will become the benchmark for all involved in city-level research, policy, planning, and investment decisions. The National Research Council is a private, non-profit institution based in Washington, DC, providing services to the US government, the public, and the scientific and engineering communities. The editors are members of the Council's Panel on Urban Population Dynamics.

Book Description
Spatial Ecology addresses the fundamental effects of space on the dynamics of individual species and on the structure, dynamics, diversity, and stability of multispecies communities. Although the ecological world is unavoidably spatial, there have been few attempts to determine how explicit considerations of space may alter the predictions of ecological models, or what insights it may give into the causes of broad-scale ecological patterns. As this book demonstrates, the spatial structure of a habitat can fundamentally alter both the qualitative and quantitative dynamics and outcomes of ecological processes. Spatial Ecology highlights the importance of space to five topical areas: stability, patterns of diversity, invasions, coexistence, and pattern generation. It illustrates both the diversity of approaches used to study spatial ecology and the underlying similarities of these approaches. Over twenty contributors address issues ranging from the persistence of endangered species, to the maintenance of biodiversity, to the dynamics of hosts and their parasitoids, to disease dynamics, multispecies competition, population genetics, and fundamental processes relevant to all these cases. There have been many recent advances in our understanding of the influence of spatially explicit processes on individual species and on multispecies communities. This book synthesizes these advances, shows the limitations of traditional, non-spatial approaches, and offers a variety of new approaches to spatial ecology that should stimulate ecological research.

Book Description
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.

Book Description
From the author of the critically acclaimed, award-winning bestseller Ishmael and its sequel, My Ishmael, comes a powerful novel with one of the most profound spiritual testaments of our time “A compelling ‘humantale’ that will unglue, stun, shock, and rearrange everything you’ve learned and assume about Western civilization and our future.”—Paul Hawken, author of The Ecology of Commerce Father Jared Osborne has received an extraordinary assignment from his superiors: Investigate an itinerant preacher stirring up deep trouble in central Europe. His followers call him B, but his enemies say he’s something else: the Antichrist. However, the man Osborne tracks across a landscape of bars, cabarets, and seedy meeting halls is no blasphemous monster—though an earlier era would undoubtedly have rushed him to the burning stake. For B claims to be enunciating a gospel written not on any stone or parchment but in our very genes, opening up a spiritual direction for humanity that would have been unimaginable to any of the prophets or saviors of traditional religion. Pressed by his superiors for a judgement, Osborne is driven to penetrate B’s inner circle, where he soon finds himself an anguished collaborator in the dismantling of his own religious foundations. More than a masterful novel of adventure and suspense, The Story of B is a rich source of compelling ideas from an author who challenges us to rethink our most cherished beliefs.
