Field naturalists have observed the activities of weasels for centuries. Their descriptions were often accurate but sometimes misinterpreted the animals' behaviors and underlying explanations for those behaviors. "Organized natural history" became one of the roots of the science of ecology in the 1920s and by the 1960s scientists had begun to study the biology of weasels with all the critical, objective advantages of modern theory and equipment. Until the first edition of this book appeared in 1989 no one had attempted to explain these results to non-specialist naturalists. Now thoroughly revised, this book will continue to be the main one-stop reference for professionals. But both kinds of knowledge are brought together here-- observations for the traditional naturalist and rigorous measurements and interpretations for modern scientists, integrated into a single, readable account.
This new edition provides a comprehensive summary of the extensive advances over the last 15 years in our knowledge of these fascinating animals. A new U.S.-based co-author reshapes the content to be more U.S.-centric. Stories about North America trappers and backwoodsmen interacting with weasels replace some (not all) of the previous stories about English gamekeepers. These changes permeate the book, so readers familiar with the first edition will recognize some material, but will find a lot that is new. Much less reliable European information quoted in the first edition was there at the time when no better information was available. Now a new NZ chapter focuses on predation problems of the species introduced to that country. This edition, much more than a simple update, is now truly an internationaltreatment and a more valuable resource.

Animals that must hunt and kill for at least part of their living are inherently interesting to many people and the role that carnivores play in biological communities attract interest from ecologists and conservation biologists. Conflicts with human activities stimulate continual debates about the management of carnivore populations, and throughout the world people seek workable solutions for human/carnivore coexistence. This concise yet authoritative handbook describes research methods and techniques for the study and conservation of all terrestrial carnivore species. Particular attention is paid to techniques for managing the human/carnivore interface. Descriptions of the latest methodologies are supported by references to case studies, whilst dedicated boxes are used to illustrate how a technique is applied to a specific land cover type, species, or particular socio-economic context. The book describes the most recent advances in modelling the patterns of animal distributions, movements, and use of land cover types, as well as including the most efficient methods to trap, handle, and mark carnivores. Carnivores are biogeographically diverse and whilst extensive scientific research has investigated many aspects of carnivore biology, not all species have been equally covered. This book is unique in its intention to provide practical guidance for carrying out research and conservation of carnivores across all species and areas of the world.
