This volume provides the first full description and analysis of the postcranial skeleton of the Tertiary canid subfamily Borophagine. Borophagines have been stereotyped as noncursorial, bone-crushing scavengers, but comparisons with Recent digitigrade carnivores reveal a surprising diversity of habit among borophagines. The author relates functional characteristics to various aspects of borophagine paleoecology, including habitat, diet, social organization, and extinction.
The Encyclopedia of Paleontology is designed to address the shortage of general reference works on both vertebrate and invertebrate paleontology and to serve the needs of students and lay persons interested in the field. As the encyclopedia aims to provide basic information, the majority of the 350 entries are devoted to explanations of paleontological concepts and techniques, examinations of the evolutionary development of particular organisms and biological features, profiles of major discoveries, and biographies of leading scientists. Each entry includes an essay and a further reading list. An international team of 200 leading experts in the field has prepared the illustrations and the essays, which range from concise descriptions to comprehensive discussions.
This book is designed as a source and reference for people interested in the history and fossil record of North American tertiary mammals. Each chapter covers a different family or order, and includes information on anatomical features, systematics, the distribution of the genera and species at different fossil localities, and a discussion of their paleobiology. Many of these groups have never been covered in this fashion before.
Xiaoming Wang and Richard H. Tedford combine their research with Mauricio Anton's impeccable reconstructions to present a remarkable portrait of canids over the past 40 million years. Wang and Tedford cull their history from the most recent scientific research conducted on the vast collections of the American Museum of Natural History and other leading institutions. With their rich fossil record, diverse adaptations to various environments, and different predatory specializations, canids are an ideal model organism for the mapping of predator behavior and morphological specializations. They also offer an excellent contrast to felids, which remain entrenched in extreme predatory specializations. The innovative illustrated approach of this book transforms the science of paleontology into a thrilling visual experience, and it forms the perfect accompaniment to an extremely important branch of animal and fossil study.
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.
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.
00 This study presents current data on vertebrate survival and extinction across the Cretaceous-Tertiary boundary in Montana. Nearly all the common taxa of reptiles (except dinosaurs), amphibians, and fish survived the end of the Cretaceous Period; extinctions were concentrated among rare groups and those found in near-shore habitats. The author concludes that ocean regression and climatic deterioration may explain these selective extinction patterns better than catastrophic hypotheses.
