Book Description
Antelope herds numbering in the tens of thousands formerly occurred across the steppes and semideserts of Eurasia and India, but these have nearly all been reduced to fractions of their earlier size; antelope populations are now fragmented across the region, and during recent decades several species have disappeared altogether. Threats include hunting, loss of habitat, population fragmentation, inadequate protected area coverage, poorly-developed administrative structures, under-resourcing of conservation programmes, and lack of enforcement of existing legislation. Rising human population growth and economic development constantly increases pressure on land and natural resources. There is a consequent need for integrated rural development, and community-based conservation projects, which have the full participation of local people at the planning and execution stages.This publication, Part 4 of the Global Antelope Survey, covers 37 countries in the region, and actions to conserve antelope populations are listed in each country report.

Book Description
This book presents an overview study about plant biogeography and vegetation of the high mountains of Central and South-West Asia, by a group of specialists familiar with its area and plant growth and ecology. This book discusses its ecological and evolutionary drivers and also its conservation priorities. Central and South-West Asia is one of the most diverse areas in the northern hemisphere and several biodiversity hotspots are concentrated in this region. Most of the biodiversity hotspots are associated with high mountain ranges of the region. Moreover, these mountains have been immigration corridors for the Central Asian flora to reach Euro-Siberian and Mediterranean regions. Despite its importance, there is no overview publication to present the plant biogeography and vegetation of these mountains and most of the publications are local or rather imprecise

Book Description
The 7-volume Encyclopedia of Biodiversity, Second Edition maintains the reputation of the highly regarded original, presenting the most current information available in this globally crucial area of research and study. It brings together the dimensions of biodiversity and examines both the services it provides and the measures to protect it. Major themes of the work include the evolution of biodiversity, systems for classifying and defining biodiversity, ecological patterns and theories of biodiversity, and an assessment of contemporary patterns and trends in biodiversity. The science of biodiversity has become the science of our future. It is an interdisciplinary field spanning areas of both physical and life sciences. Our awareness of the loss of biodiversity has brought a long overdue appreciation of the magnitude of this loss and a determination to develop the tools to protect our future. Second edition includes over 100 new articles and 226 updated articles covering this multidisciplinary field— from evolution to habits to economics, in 7 volumes The editors of this edition are all well respected, instantly recognizable academics operating at the top of their respective fields in biodiversity research; readers can be assured that they are reading material that has been meticulously checked and reviewed by experts Approximately 1,800 figures and 350 tables complement the text, and more than 3,000 glossary entries explain key terms

Book Description
The first complete history of Central Eurasia from ancient times to the present day, Empires of the Silk Road represents a fundamental rethinking of the origins, history, and significance of this major world region. Christopher Beckwith describes the rise and fall of the great Central Eurasian empires, including those of the Scythians, Attila the Hun, the Turks and Tibetans, and Genghis Khan and the Mongols. In addition, he explains why the heartland of Central Eurasia led the world economically, scientifically, and artistically for many centuries despite invasions by Persians, Greeks, Arabs, Chinese, and others. In retelling the story of the Old World from the perspective of Central Eurasia, Beckwith provides a new understanding of the internal and external dynamics of the Central Eurasian states and shows how their people repeatedly revolutionized Eurasian civilization. Beckwith recounts the Indo-Europeans' migration out of Central Eurasia, their mixture with local peoples, and the resulting development of the Graeco-Roman, Persian, Indian, and Chinese civilizations; he details the basis for the thriving economy of premodern Central Eurasia, the economy's disintegration following the region's partition by the Chinese and Russians in the eighteenth and nineteenth centuries, and the damaging of Central Eurasian culture by Modernism; and he discusses the significance for world history of the partial reemergence of Central Eurasian nations after the collapse of the Soviet Union. Empires of the Silk Road places Central Eurasia within a world historical framework and demonstrates why the region is central to understanding the history of civilization.

Book Description
Humans is a concise, jargon-free introduction to four-field anthropology. This book outlines and breaks down a complex discipline to identify some of the most important and relevant questions in anthropology. It provides students with an understanding of the unity of the human species, the adaptation of societies to their environments (physical and political), and an appreciation of the power of socialization into a culture. The authors ensure that the book takes a balanced approach to all four fields, covering topics such as cultural relativism, humans as a biological species, primates, communicating, economics, and religion. Pedagogical features include a study guide and notes for instructors. This second edition is fully updated with brand new material on evolution, genetics, and archaeology to reflect the latest research and recent changes in the field. This book is an ideal introduction for students embarking on an anthropology course for the first time.

Book Description
This book explains forest and woody biomass harvest, harvesting machines, systems, logistics, supply chain management, best management practices, harvest scheduling and carbon sequestration. It also covers applications of harvesting principles in forest and biomass management practices. The book provides an in-depth understanding of functions and applications of current and future harvesting technologies, the unique characteristics of harvesting machine with respect to cost, productivity, and environmental impacts. Special features include harvest machine illustrations and images of field operations, tabular presentations of filed studies of forest operations and detailed modelling processes for forest and biomass harvest logistics and supply chain management. Specifically, the book is designed for students, researchers, educators, and practitioners in the field of forest and biomass harvest and logistics. The book’s contents have been tested in teaching as the Harvesting Forest Product class for undergraduates and graduates in the Division of Forestry and Natural Resources at West Virginia University since 2000. The information contained in this book is a robust reference resource for students who would be future forest and biomass managers, timber contractors, entrepreneurs, researchers, and educators in the fields of forest and biomass operations, engineering, and resource management.
