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.
Download or read book The Origins of Vowel Systems written by Bart De Boer and published by Oxford University Press, USA. This book was released on 2001 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses universal tendencies of human vowel systems from the point of view of self-organization. It uses computer simulations to show that the same universal tendencies found in human languages can be reproduced in a population of artificial agents. These agents learn and use vowels with human-like perception and production, using a learning algorithm that is cognitively plausible. The implications of these results for the evolution of language are then explored.
Download or read book Systems Analysis and Simulation in Ecology written by Bernard C. Patten and published by Elsevier. This book was released on 2013-09-17 with total page 609 pages. Available in PDF, EPUB and Kindle. Book excerpt: Systems Analysis and Simulation in Ecology, Volume II, concludes the original concept for Systems Analysis and Simulation in Ecology, and at the same time initiates a continuing series under the same title. The original idea, in 1968, was to draw together a collection of systems ecology articles as a convenient benchmark to the state of this emerging new field and as a stimulus to broader interest. These purposes will continue to motivate the series in highlighting, from time to time, accomplishments, trends, and prospects. The present volume is organized into four parts. Part I outlines for ecologists the concepts upon which systems science as a discipline is built. Part II presents example applications of systems analysis methods to ecosystems. Part III is devoted to new theory, including an investigation into the feasibility of several nonlinear formulations for use in compartment modeling of ecosystems; and the important topic of connectivity in systems. Part IV presents a sampling of systems ecology applications. It provides a reasonably balanced and accurate picture of the practical capability of ecological systems analysis and simulation. Performance does not come up to publicity, but prospects for rapid improvement are good given a willingness to let pragmatism guide sound scientific development without demanding unrealistic short-term successes.

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 Structured Population Models in Biology and Epidemiology written by Pierre Magal and published by Springer. This book was released on 2008-04-12 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this new century mankind faces ever more challenging environmental and publichealthproblems,suchaspollution,invasionbyexoticspecies,theem- gence of new diseases or the emergence of diseases into new regions (West Nile virus,SARS,Anthrax,etc.),andtheresurgenceofexistingdiseases(in?uenza, malaria, TB, HIV/AIDS, etc.). Mathematical models have been successfully used to study many biological, epidemiological and medical problems, and nonlinear and complex dynamics have been observed in all of those contexts. Mathematical studies have helped us not only to better understand these problems but also to ?nd solutions in some cases, such as the prediction and control of SARS outbreaks, understanding HIV infection, and the investi- tion of antibiotic-resistant infections in hospitals. Structuredpopulationmodelsdistinguishindividualsfromoneanother- cording to characteristics such as age, size, location, status, and movement, to determine the birth, growth and death rates, interaction with each other and with environment, infectivity, etc. The goal of structured population models is to understand how these characteristics a?ect the dynamics of these models and thus the outcomes and consequences of the biological and epidemiolo- cal processes. There is a very large and growing body of literature on these topics. This book deals with the recent and important advances in the study of structured population models in biology and epidemiology. There are six chapters in this book, written by leading researchers in these areas.
Download or read book The Emergence of Civilization written by Charles Keith Maisels and published by Routledge. This book was released on 2003-12-16 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Emergence of Civilisation is a major contribution to our understanding of the development of urban culture and social stratification in the Near Eastern region. Charles Maisels argues that our present assumptions about state formation, based on nineteenth century speculations, are wrong. His investigation illuminates the changes in scale, complexity and hierarchy which accompany the development of civilisation. The book draws conclusions about the dynamics of social change and the processes of social evolution in general, applying those concepts to the rise of Greece and Rome, and to the collapse of the classical Mediterranean world.
Download or read book Second Promised Land written by Harry H. Hiller and published by McGill-Queen's Press - MQUP. This book was released on 2009-05-01 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: Combining statistical analysis and ethnographic study, Harry Hiller uncovers two waves of in-migration to Alberta. His innovative approach begins with the individual migrant and analyzes the relocation experience from origin to destination. Through interviews with hundreds of migrants, Hiller shows that migration is complex and dynamic, shaped not just by what Alberta offers but also prompted by a process that begins in the region of origin which makes migration possible, and helps determine whether migrants stay or return home. By combining a social psychological approach with structural factors such as Alberta’s transition from a regional hinterland province to its emerging role the global system, discussions of gender, the internet, and folk culture, Second Promised Land provides a multi-dimensional and deeply human account of a contemporary Canadian phenomenon.
Download or read book Large Mammals and a Brave People written by Stuart A. Marks and published by Routledge. This book was released on 2017-07-12 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Valley Bisa people inhabit the Luangwa Valley in central Zambia. Among them, the hunter, who tracks such large game as the lion, elephant, and buffalo, commands great respect and esteem from the other members of the lineage who traditionally rely on him for their subsistence and protection. Although the social organization and technology of the Bisa people have undergone tremendous change in the last one hundred years, the role of hunter retains its social importance, and the legitimizing hunting rituals have their roots in local history. Drawing on data collected during his fieldwork among the Bisa continuing since the 1960s, Stuart Marks describes the changes that have occurred in hunting patterns, the sociological variables that govern an individual's decision to become a hunter, and the common cosmological convictions that hunters bring to their profession. Available for the first time in paperback, the new introduction and afterword to this edition reflect on methodological and ideological changes in the anthropological study of African peoples as well as updating the circumstances of the Bisa people since the book's first appearance in 1976. Through the interventions of the larger national society the Bisa have lost much of their land and access to important portions of their resources while experiencing repression in their struggles to maintain livelihoods with what local assets are left. Nevertheless, Marks notes that they face their hardships with tolerance, integrity, persistence, and humility. The general reader, as well as prehistorians and anthropologists concerned with human evolution and hunting societies, will find this volume useful. It will also be of interest to wildlife managers and ecologists.

Download or read book Econophysics and Data Driven Modelling of Market Dynamics written by Frédéric Abergel and published by Springer. This book was released on 2015-01-27 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the works and research findings of physicists, economists, mathematicians, statisticians, and financial engineers who have undertaken data-driven modelling of market dynamics and other empirical studies in the field of Econophysics. During recent decades, the financial market landscape has changed dramatically with the deregulation of markets and the growing complexity of products. The ever-increasing speed and decreasing costs of computational power and networks have led to the emergence of huge databases. The availability of these data should permit the development of models that are better founded empirically, and econophysicists have accordingly been advocating that one should rely primarily on the empirical observations in order to construct models and validate them. The recent turmoil in financial markets and the 2008 crash appear to offer a strong rationale for new models and approaches. The Econophysics community accordingly has an important future role to play in market modelling. The Econophys-Kolkata VIII conference proceedings are devoted to the presentation of many such modelling efforts and address recent developments. A number of leading researchers from across the globe report on their recent work, comment on the latest issues, and review the contemporary literature.
