Download or read book Using Science to Improve the BLM Wild Horse and Burro Program written by National Research Council and published by National Academies Press. This book was released on 2013-10-04 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

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 Nursing Staff in Hospitals and Nursing Homes written by Institute of Medicine and published by National Academies Press. This book was released on 1996-03-27 with total page 558 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hospitals and nursing homes are responding to changes in the health care system by modifying staffing levels and the mix of nursing personnel. But do these changes endanger the quality of patient care? Do nursing staff suffer increased rates of injury, illness, or stress because of changing workplace demands? These questions are addressed in Nursing Staff in Hospitals and Nursing Homes, a thorough and authoritative look at today's health care system that also takes a long-term view of staffing needs for nursing as the nation moves into the next century. The committee draws fundamental conclusions about the evolving role of nurses in hospitals and nursing homes and presents recommendations about staffing decisions, nursing training, measurement of quality, reimbursement, and other areas. The volume also discusses work-related injuries, violence toward and abuse of nursing staffs, and stress among nursing personnelâ€"and examines whether these problems are related to staffing levels. Included is a readable overview of the underlying trends in health care that have given rise to urgent questions about nurse staffing: population changes, budget pressures, and the introduction of new technologies. Nursing Staff in Hospitals and Nursing Homes provides a straightforward examination of complex and sensitive issues surround the role and value of nursing on our health care system.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Spatial Ecology written by David Tilman and published by Princeton University Press. This book was released on 2018-06-05 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Population Dynamics written by Ralph Thomlinson and published by . This book was released on 1965 with total page 616 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is divided into four parts. Part 1 supplies the historical setting, a brief survey of research procedures, and a theoretical context - all useful before setting out to analyze the dynamics of population. Part II exposes the heart of demography and is organized around the three basic variables. Part III branches out to consider various ramifications of demographic phenomena: cities, food, industrial products, power politics, and instruments of population control. Part IV abstracts information concerning demographic attributes of individuals and nations. The book as a whole attempts to trace world and local changes in human population, especially during the last two centuries. Its purpose is implicit in its title: namely, to explain the changing population situation and the processes and agencies which produce demographic alterations.
Download or read book Theory of Populations written by Alexandr N Tetearing and published by Lulu.com. This book was released on 2016-11-29 with total page 614 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book is devoted to the theory of development of the biological systems. The fundamental equation of life of a biological population, based on the general physical principles, allows us to get all the basic equations of population dynamics, describing the development of the populations under various environmental conditions. The equations describe the population transition that occurred in our human population in the late 20-th century. This transition may indicate the fact that the human population consists of two super-races - the old "slow" race, and new fast-growing human race that appeared on Earth relatively recently. The separate chapter presents the base classification of predator-prey systems. The classification consists of ninety-six different equation systems. The book is addressed to a broad auditorium of biologists, ecologists, and demographers, as well as readers, interested in the development of the biological populations. Translated from Russian.
Download or read book Complex Population Dynamics written by Peter Turchin and published by Princeton University Press. This book was released on 2013-02-15 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: Why do organisms become extremely abundant one year and then seem to disappear a few years later? Why do population outbreaks in particular species happen more or less regularly in certain locations, but only irregularly (or never at all) in other locations? Complex population dynamics have fascinated biologists for decades. By bringing together mathematical models, statistical analyses, and field experiments, this book offers a comprehensive new synthesis of the theory of population oscillations. Peter Turchin first reviews the conceptual tools that ecologists use to investigate population oscillations, introducing population modeling and the statistical analysis of time series data. He then provides an in-depth discussion of several case studies--including the larch budmoth, southern pine beetle, red grouse, voles and lemmings, snowshoe hare, and ungulates--to develop a new analysis of the mechanisms that drive population oscillations in nature. Through such work, the author argues, ecologists can develop general laws of population dynamics that will help turn ecology into a truly quantitative and predictive science. Complex Population Dynamics integrates theoretical and empirical studies into a major new synthesis of current knowledge about population dynamics. It is also a pioneering work that sets the course for ecology's future as a predictive science.

Download or read book Complex Population Dynamics written by Bernd Blasius and published by World Scientific. This book was released on 2007 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: This collection of review articles is devoted to the modeling of ecological, epidemiological and evolutionary systems. Theoretical mathematical models are perhaps one of the most powerful approaches available for increasing our understanding of the complex population dynamics in these natural systems. Exciting new techniques are currently being developed to meet this challenge, such as generalized or structural modeling, adaptive dynamics or multiplicative processes. Many of these new techniques stem from the field of nonlinear dynamics and chaos theory, where even the simplest mathematical rule can generate a rich variety of dynamical behaviors that bear a strong analogy to biological populations.

Download or read book Population Dynamics written by T. N. E. Greville and published by Elsevier. This book was released on 2014-05-12 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Population Dynamics covers the proceedings of a symposium conducted by the Mathematics Research Center, The University of Wisconsin, Madison on June 19-21, 1972. The book focuses on the application of mathematics to the study of human population growth. The selection first offers information on population waves and the properties of a stochastic attraction model. Discussions focus on social distance, limiting behavior of the model, mathematical development, population increase and retirement pensions, natural periodicity in the demographic system, trends in generational stability, mobility in unstable populations, and the Easterlin effect. The text then takes a look at the sampling frame as a determinant of observed distributions of duration variables and comparison of alternative marriage models, including plausible marriage models, axioms for marriage functions, birth intervals, and computer simulation of prospective and interior birth interval lengths. The manuscript ponders on contraceptive impact over several generations, estimation of the risk of conception from censored data, and influence of cause of death structure on age-patterns of mortality. Topics include distributions of conception times, simulation of experiments, potential fertility of users, and length of protection. The selection is a valuable reference for researchers interested in population dynamics.
