David Macdonald - Böcker

The badgers of Wytham Woods (Oxford, UK) have been studied continuously and intensively by David Macdonald for almost 50 years (25 of them with his former student and co-author Chris Newman), generating a wealth of data pertaining to every facet of their ecology and evolution. Through a mix of accessible, highly readable prose and cutting-edge science, the authors weave a riveting scientific story of the lives of these intriguing creatures, highlighting the insights offered to science more broadly through badgers as a model system. They provide a paradigm - from population down to molecule - for a deeper understanding of mammalian behaviour, ecology, epidemiology, evolutionary biology, and conservation. The real value of this long-term study is particularly apparent with current and globally relevant challenges such as climate change, disease epidemics, and senescence. This unique dataset enables us to examine these issues in a context that only a half-century experiment can reveal.The Badgers of Wytham Woods will appeal to a broad audience of professional academics (especially carnivore and mammalian biologists), researchers and students at all levels, governmental and non-governmental wildlife bodies, and to the natural historian fascinated by wild animals and the remarkable processes of nature they exemplify.

The editors utilize their 50 years of combined experience in professional engagement with the behaviour and ecology of wild felids to draw together a unique network of the world's most respected and knowledgeable experts. For the first time, this inter-disciplinary research programme is brought together within a single volume. Beginning with a complete account of all 36 felid species, there follow 8 comprehensive review chapters that span all the topics most relevant to felid conservation science, including evolution and systematics, felid form and function, genetic applications, behavioural ecology, management of species that come into conflict with people and control of international trade in felid species, conservation tools/techniques, ex situ management, and felid diseases. 19 detailed case studies then delve deeply into syntheses of the very best species investigations worldwide, written by all the leading figures in the field. These chapters portray the unique attributes of the wild felids, describe their fascinating (and conflicting) relationship with humans, and create an unparalleled platform for future research and conservation measures. A final chapter analyses the requirements of, and inter-disciplinary approaches to, practical conservation with cutting-edge examples of conservation science and action that go far beyond the cat family.

'Afghanistan is seen as a major drug producer, but its own people are becoming the victims. ... David Macdonald not only explores [the reasons for this] but also tells an addictive tale that is difficult to resist.' Shirazuddin Siddiqi, BBC'This stunning book provides a first hand account of the Afghan drug problem. David Macdonald has written the definitive text on drugs in Afghanistan.' Professor Gerry Stimson, Executive Director, International Harm Reduction Association 'David Macdonald tells a story about the diversity of drug use in Afghanistan that no one has ever told before.' Ethan Nadelmann, Executive Director, Drug Policy Alliance, New YorkAfghanistan is the world's largest producer of opium and heroin. This book explores the devastating impact that the drugs trade has had on the Afghan people. Author David Macdonald has worked as a drugs advisor to the UN. Based on his extensive experience, this book breaks down the myths surrounding the cultivation and consumption of drugs, providing a detailed analysis of the history of drug use within the country. He examines the impact of over 25 years of continuous conflict, and shows how poverty and instability has led to an increase in drugs consumption. He also considers the recent rise in the use of pharmaceutical drugs, resulting in dangerous chemical cocktails and analyses the effect of Afghanistan's drug trade on neighbouring countries.

Practical Machinery Safety aims to provide you with the knowledge to tackle machinery safety control problems at a practical level whilst achieving compliance with national and international standards.The book highlights the major international standards that are used to support compliance with EU regulations and uses these standards as a basis for the design procedures. It looks at the risk assessment processes used to identify hazards and to quantify the risks inherent in a machine. It introduces the concepts of safety categories as defined by standard EN954-1 (Safety of Machinery) and illustrates the principles of failsafe design, fault tolerance and self-testing.It also provides an introduction to machinery protection devices such as guards, enclosures with interlocks and guard-monitoring relays, locking systems, safety mats, photo-electric and electro-sensitive principles and the application of light curtains, a study of Safety Control System techniques, and introduces the principles of safety-certified PLCs.

Since 2001, when the previous edition of this award-winning encyclopedia was published, new advances in molecular evolution and changes in how scientists view the classification of mammals resulted in a restructuring of the older classification system. This new approach means that certain animals, such as moles, shrews, and insectivores, are now reclassed based on molecular and other biological evidence that has been collected over the last five years. In three comprehensive, beautifully illustrated volumes, ""The Encyclopedia of Mammals, Second Edition"" brings the extensive research on this topic up to date as it reflects the latest thinking on mammalian evolution. All information in this set has been reviewed, updated, and expanded from the first edition, including six new special feature sections and an abundance of full-color photographs and illustrations. With the emergence of new archaeological evidence, the discussion of the age and evolution of man has been reopened, and this set addresses the role and development of mammalian evolution in the 21st century. Written by a team of advisory editors and some of the world's leading biologists, ""The Encyclopedia of Mammals, Second Edition"" remains unparalleled in scope and authority. New features include: current information on various threats to endangered species during the 21st century; two new essays covering recent developments in mammalian conservation; a completely new essay in the Primates section on the evolution of hominids; and a featured essay on man as a single species.

How European settlers learned of the vast North American continent was often through the accounts of men who individually or in groups trekked into the wilderness. Their chief motivation was ascertaining or obtaining natural resources for commerce, such as beaver pelts and other hides, which took them from the eastern forests, across the Great Plains, into the Rocky Mountains, or to the Pacific Ocean—years before the celebrated Lewis and Clark Expedition. Their information about Indigenous Peoples, the landscape, and the waterways influenced the course of North American history. While a few frontiersmen, such as Daniel Boone, are well known, most—predominantly Canadian and French—are forgotten, their activities recalled only by scholars. Encountering North America: Profiles of Frontiersmen, 1650–1820 by David MacDonald and Raine Waters presents men whose far-reaching explorations opened the continent to further settlements and trade routes. One was torn between the French and British, while another between Indigenous and white societies. One was Spanish. One was an administrator, a force for order in an unsettled world. Two were certainly homicidal. As with the authors’ previous volumes on failed European attempts to colonize both North and South America, each narrative is supported by discursive commentary on the primary source materials available.
