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.

The Chang Tang, the vast, remote Tibetan steppe, is one of the most forbidding places on earth. Yet this harsh land is home to a unique assemblage of large mammals, including Tibetan antelope, gazelle, argali sheep, wild ass, wild yak, wolves, snow leopards, and others. Since 1985, George B. Schaller and his Chinese and Tibetan co-workers have surveyed the flora and fauna of the Chang Tang. Their research provides the first detailed look at the natural history of one of the world's least known ecosystems.

When the first field study of the Florida panther took place in 1973, so little was known about the animal that many scientists believed it was already extinct. During more extensive research conducted from 1981 to 1986, panthers were proven to exist, but the handful of senile, anemic, and parasite-infested specimens that were captured indicated a grim future. During those early years a remarkably enduring image of the panther was born, and despite voluminous data gathered over the next decade that showed the panther to be healthy, long-lived, and reproducing, that earlier image has yet to be dispelled. For nine years, biologist David S. Maehr served as project leader of the Florida Panther Study Project, helping to gather much of the later, surprisingly positive data. In The Florida Panther, he presents the first detailed portrait of the animal -- its biology, natural history, and current status -- and a realistic assessment of its prospects for survival. Maehr also provides an intriguing look at the life and work of a field biologist: how captures are made, the intricacies of radio-telemetry tracking, the roles of various team members. He describes the devastating intrusion of politics into scientific work, as he discusses the widespread problems caused by the failure of remote and ill-informed managers to provide needed support and to communicate effectively to the public the goals and accomplishments of the scientists. He examines controversial efforts to establish a captive breeding program and to manipulate the Florida panther's genetic stock with the introduction of relatives from west Texas. Protection of high-quality habitat, much of it in the hands of private landowners, is the key to the long-term survival of the Florida panther. Unless agency decisionmakers and the public are aware of the panther's true situation, little can be done to save it. This book will play a vital role in correcting widespread misconceptions about the panther's current condition and threats to its survival.

Developing countries in Africa, Asia, and Latin America are increasingly influenced by human-induced environmental changes. It is crucial that sustainable development be based on insights into these expanding processes--conservation as well as deterioration. Nature's Geography offers a new perspective on the geographical nature of these changes. The book reveals how human-environment relations must be understood at multiple scales and time frames. Editors Karl S. Zimmerer and Kenneth R. Young have forged an exciting group of case studies from distinguished geographers focusing on high mountains, tropical forests, and lowlands, as well as humid and arid-semiarid landscapes. Each chapter analyzes the implications for meshing environmental protection and sound resource use with development. The case studies evaluate three topics: spatial habitat fragmentation and forest dynamics; disturbances in mountain ecosystems; and the major activities of settled areas, chiefly farming, livestock-raising, and forestry. Included are analyses of interactions involving wildlife, such as primates and wild pandas; assessment of fire impacts and road-building; long-term forest management as well as recent techniques; and the role of environmental variation and ecosystem properties in agriculture and rangeland. Nature's Geography demonstrates the vital importance of advancing a new approach to geography. This definitive study of landscape change and environmental dynamics will have wide appeal for those interested in geography, ecology, environmental studies, conservation biology, and development studies.
