Decline and Recovery of the Island Fox


Book Description

Native only to the California Channel Islands, the island fox is the smallest canid in North America. Populations on four of the islands were threatened to extinction in the 1990s due to human-mediated predation and disease. This is the first account of the natural history and ecology of the island fox, illustrating both the vulnerability of island ecosystems and the efficacy of cooperative conservation measures. It explains in detail the intense conservation actions required to recover fox populations, such as captive breeding and reintroduction, and large-scale ecosystem manipulation. These actions were successful due in large part to extraordinary collaboration among the scientists, managers and public advocates involved in the recovery effort. The book also examines the role of some aspects of island fox biology, characteristic of the 'island syndrome', in facilitating their recovery, including high productivity and an apparent adaptation to periodic genetic bottlenecks.




The Biology and Conservation of Wild Canids


Book Description

No group of wild mammals so universally captures the emotions of people world-wide than do wild canids. That emotion can be enchantment and fascination, but it can also be loathing, because the opportunism that is the hallmark of the dog family also leads them into conflict with humans. In the developed world at least, the fascination with wild canids doubtless stems from people's captivation with domestic dogs - everybody feels they are an expert on canids! While most people may be familiar with only the better known members of the dog family, such as the grey wolf and the red fox, there are in fact 36 species of wolves, dogs, jackals and foxes. They attract hugely disproportionate interest from academics, conservationists, veterinarians, wildlife managers and the general public. This book brings together in single volume an astonishing synthesis of research done in the last twenty years and is the first truly compendious synthesis on wild canids. Beginning with a complete account of all 36 canid species, there follow six review chapters that emphasise topics most relevant to canid conservation science, including evolution and systematics, behavioural ecology, population genetics, diseases, conflict/control of troublesome species, and conservation tools. Fifteen detailed case studies then delve deeply into the very best species investigations currently available written by all the leading figures in the field. Much of the material is previously unpublished and will make fascinating reading far beyond the confines of canid specialists. These chapters portray the unique attributes of wild canids, their fascinating (and conflictive) relationship with man, and suggestions for future research and conservation measures for the Canidae. While most canid species are widespread and thrive in human dominated landscapes, several are in severe jeopardy; habitat loss, illegal hunting, persecution by farmers and disease all imperil dwindling populations. A final chapter analyses the requirements of, and approaches to, practical conservation, with lessons that go far beyond the dog family. It concentrates particular attention on priorities for the protection of the most threatened canid species, including the red wolf, African wild dog, Ethiopian wolf, Island fox and Darwin's fox. The wild canids provide examples that will thrill the evolutionary biologists and theoretician, enthral the natural historian and challenge the conservationist and wildlife manager. Anybody interested in evolutionary and behavioural biology, in mammals, in the environment, or in conservation will find much that is new and enriching in this book.







Carnivore Behavior, Ecology, and Evolution


Book Description

Because carnivores are at the top of the food chain, their status is an important indicator of the health of the world ecosystem. They are intensely interesting to zoologists and uniquely intriguing to the general public. Devoted primarily to terrestrial carnivores, this volume focuses on such themes as carnivore reintroduction programs and the ethics of studying carnivores, drawing examples from a variety of species. The need to evaluate new conceptual ideas and empirical data inspired this volume of Carnivore Behavior, Ecology, and Evolution, a complement to the original book. In the eight years since publication of the first volume, conservation has emerged as a thematic imperative. The study of carnivores has become even more important in raising and resolving crucial biological problems. Differential rates of mortality in the giant panda and other endangered carnivores are now known to influence dispersal and life history patterns basic to these species' survival. Reintroduction efforts of the black-footed ferret and the red wolf are establishing essential guidelines for preservation and management of endangered species. Studies of the African lion and the dwarf mongoose illustrate the power of new genetic techniques of DNA fingerprinting for understanding the evolution of social behavior.







Animal Skulls


Book Description

This reference and guidebook offers illustrations, descriptions, and measurements for the skulls of some 275 animal species found throughout North America. The skull is the key anatomical feature used to identify an animal and understand many of its behaviors. This book describes in words and pictures the bones and regions of the skull important to identification, including illustrations of all the bones in the cranium, leading to a greater understanding of a creature's place in the natural world. With life-size drawings, this guide is a reference for wildlife professionals, trackers, and animal-lovers.
