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.

Modern biology is increasingly focused on the role of repetitive anatomical structures in the embryological construction of organisms. The discovery of the homeobox (Hox) genes by Edward Lewis in 1978 ushered in a series of stunning revelations such as the fundamental commonality of insect segments and mammalian vertebrae - a wild and ridiculed idea first proposed by Etienne Geoffroy Saint-Hilaire in 1822 that has now been proven correct. Axial Character Seriation in Mammals is an unabridged edition of the 1986 Harvard University PhD Thesis of Aaron G. Filler, MD, PhD that pioneered our modern reassessment of mammalian vertebrae in the light of the new homeotic biology. As Dr. Filler points out in fascinating detail, the leading explanations of similarity among animals before Darwin were arrayed around the vertebrae of the spine in works by Sir Richard Owen, Johann Wolfgang Goethe and Geoffroy Saint-Hilaire. This was the theoretical structure that was overturned and demolished by Darwin's ideas about similarity due to common descent. In a stunning reversal, modern homeotic genetics has shown that repeating structures are indeed critical to understanding animal similarity. This work is the first study of the modern era that views vertebrae as a key to unlocking the way in which Nature has organized repeating biological structures. For the 150 years since the Great Academy Debate of 1830 appeared to demolish Geoffroy Saint-Hilaire's ideas, vertebrae have been seen as no more than some bones in Vertebrate animals that are involved in support and locomotion. Axial Character Seriation in Mammals, however, explores the fascinating traces of how the morphogenetic genes sculpt and organize serially repeating structures, thus re-establishing the vertebrae as a legitimate and compelling subject of modern science.

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.

The mammalian order Carnivora is characterized by an incredible range of morphological, ecological, and behavioral variation. Carnivores can be as small as the 100-gram least weasel or as large as the 800-kilogram polar bear. Their reproductive rate can vary from one offspring every five years, as with some black bears, to three litters a year, as with the dwarf mongoose. Group sizes can be traced along a wide continuum, from the solitary ermine to the monogamous golden jackal to the large extended packs of as many as 80 spotted hyenas. Until recently the general habits of most wild carnivore species were inadequately understood. In the last decade, however, improved technologies, including the use of radiotelemetry and night-vision scopes, have led to many important discoveries. This book is at once a critical summary and an evaluation of current research on carnivores. A worthy successor to R.F. Ewer's monumental volume, The Carnivores (Cornell University Press), it is the work of 30 leading carnivore biologists, who here assemble comparative data on the basic anatomical, behavioral, ecological, physiological, reproductive, and evolutionary characteristics of this group. After a general introduction to the Carnivora, the volume is divided in three parts, each of which begins with a brief introduction outlining its main themes. Part I, Behavior, covers acoustic and olfactory communication, behavioral development, behavioral ecology of canids and hyaenids, modes of solitary living, and group living. In Part II, Ecology, topics include feeding ecology of the giant panda and Asiatic black bear, adatpations for aquatic living, ecological constraints on predation in felids, consequences of small size in mustelids, rate of basal metabolism and food habits, and reproductive output. Part III, Evolution, deals with the morphological approaches to phylogeny, and the fossil record. An appendix presents a complete classification of the Carnivora, including topics of continuing controversy. Highlighting recent developments in the study of the Carnivora and areas for further research, this broad synthesis will be of great value of students and researchers in animal behavior, behavioral ecology, wildlife ecology, mammalogy, paleontology, systematics, and evolution theory. It will also encourage realistic conservation programs to manage rapidly diminishing populations and will elucidate particular features of the carnivores for nonspecialist readers.
