Very Short Introductions: Brilliant, Sharp, Inspiring Extinction is a natural process. In geological time there have been several periods of mass extinction. One of these periods is unfolding right now but all the evidence suggests that current extinction rates are between a hundred and a thousand times greater than the background rate. To put this in to context, a quarter of all known mammalian species is at risk. The current extinction crisis is unique, because it is caused by the impact of one species, humans, on all others. This acceleration of species loss, and the much more widespread reductions in the populations of many species, is not merely a tragedy in aesthetics, it is also a threat to the quality of human life, indeed to the entire human enterprise. Biodiversity, the diversity of life, is not only fascinating and beautiful, it is the engine of all the world's natural cycles, and the source of many of the resources on which humanity depends. Concern about biodiversity conservation is, therefore, not merely the preoccupation of a few enthusiastic naturalists - it is the lifeline business of everybody. In this Very Short Introduction, David Macdonald introduces the concept of biodiversity and the basic biological processes that it involves - evolutionary, ecological, and behavioral. He considers the various threats to biodiversity, their impacts, and some of the solutions to the problems; concluding by considering the future of biodiversity conservation. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

The most numerous of the world's invasive species, rodent pests have a devastating impact on agriculture, food, health and the environment. In the last two decades, the science and practice of rodent control has faced new legislation on rodenticides, the pests' increasing resistance to chemical control and the impact on non-target species, bringing a new dimension to this updated 2nd edition and making essential reading for all those involved in rodent pest control, including researchers, conservationists, practitioners and public health specialists.

The capybara is the neotropical mammal with the highest potential for production and domestication. Amongst the favorable characteristics for domestication we can list its high prolificacy, rapid growth rate, a herbivorous diet, social behavior and relative tameness. The genus (with only two species) is found from the Panama Canal to the north of Argentina on the east of the Andes. Chile is the only country in South America where the capybara is not found. The species is eaten all over its range, especially by poor, rural and traditional communities engaged in subsistence hunting. On the other hand, in large urban settlements wildlife is consumed by city dwellers as a delicacy. The sustainable management of capybara in the wild has been adopted by some South American countries, while others have encouraged capybara rearing in captivity.

As the rates of lifestyle diseases such as obesity, diabetes, and heart disease continue to rise, the development of effective tools that can help people adopt and sustain healthier habits is becoming ever more important. Mobile computing holds great promise for providing effective support for helping people manage their health in everyday life. Yet, for this promise to be realized, mobile wellness systems need to be well designed, not only in terms of how they implement specific behavior-change techniques but also, among other factors, in terms of how much burden they put on the user, how well they integrate into the user's daily life, and how they address the user's privacy concerns. Designing for all of these constraints is difficult, and it is often not clear what tradeoffs particular design decisions have on how a wellness application is experienced and used. Designing for Healthy Lifestyles: Design Considerations for Mobile Technologies to Encourage Consumer Health and Wellness assesses different design approaches to common features of mobile wellness applications, and discusses the tradeoffs that are inherent in those approaches. It also outlines the key challenges that human-computer interaction researchers and designers will need to address to move the state of the art for mobile wellness technologies forward.

This is a definitive book on the dog family, dealing with many aspects of the biology and conservation of wolves, dogs, jackals and foxes. It covers many topics relevant to modern conservation science, and features detailed case studies of many canid species across the globe. A must-have book for all scientists studying carnivores, predators, cooperative breeding, and social systems. A useful text for both undergraduate and graduate courses in behavioural ecology and conservation biology. Wild canids are the ancestors of the domestic dog and there are a large number of wolf and domestic dog enthusiasts who will be engaged by the contents of this book.

Because carnivores are at the top of the food chain, it is often argued that protecting them will afford adequate protection to other taxa as well. In the past ten years, theoretical and empirical studies on carnivores have developed very quickly. This volume reviews and summarizes the current state of the field, describes limitations and opportunities for carnivore conservation, and offers a conceptual framework for future research and applied management. It will be of interest to students and researchers of conservation biology, mammalogy, animal behavior, ecology, and evolution.

Although they are highly intelligent, ruthless predators, carnivores are increasingly rare. From the dwarf mongoose to the polar bear, carnivores are at once respected and misunderstood, invoking both fear and curiosity in the humans with whom they share their world. Ronald M. Nowak celebrates these fascinating mammals in Walker's Carnivores of the World. This comprehensive guide, featuring 225 illustrations, covers the world's eight terrestrial families of carnivores. Each generic account comprises scientific and common names, number and distribution of species, physical attributes, measurements, hunting and social activity, reproduction, habitat, population dynamics, longevity, and status of threatened species. A thought-provoking overview by David W. Macdonald and Roland W. Kays is packed with results of the latest field and laboratory research on topics ranging from evolutionary history to the adaptive value of fur patterns. Emphasizing the interplay of social life, morphology, and predatory behavior, it provides an up-to-date panorama of the world's carnivores. Ernest P. Walker (1891-1969) began work on Mammals of the World in the early 1930s, when he became assistant director of the National Zoo in Washington. Ronald M. Nowak was senior author of the fourth edition and author of the fifth and sixth editions of Walker's Mammals of the World. He served as editorial consultant for four editions of National Geographic Society's Wild Animals of North America.
