Proceedings of the 19th annual meeting of the International Society on Oxygen Transport to Tissues, held August 1991, in Willemstad, Curacao. Among the topics: the field of bioengineering; the oxygen molecule and its course from air to cell; the problem of diffusion in lung, blood, and tissue; patho"

Consolidates the information presented at the NATO Advanced Research Workshop held at the U. of Salamanca, Spain in September 1991, at which leading scientists working on the cochlear nucleus presented and discussed their recent results. The studies presented in this volume reemphasize the current k

The Natural History of the Doucs and Snub-nosed Monkeys provides a comprehensive introduction to the biology of some of the rarest and least-known nonhuman primates. Virtually unstudied and unknown until 20 years ago, the doucs and snub-nosed monkeys occupy some of the most remote habitats of eastern Asia and exhibit some of the most unusual adaptations of any nonhuman primates. The volume provides detailed information on these rare Asian primates that will be useful to practitioners of evolutionary biology, field and laboratory primatology, systematics, field ecology, and conservation biology.

Marine mammals are among the most interesting and threatened species on Earth. This CD-ROM gives a complete overview of all sea mammals of the world with detailed full-colour drawings and spectacular underwater photographs as well as sound recordings for most species. Included also are an interactive identification key and distribution maps, and an illustrated glossary defining more than 250 scientific terms; the entire text is hyperlinked. Marine Mammals of the World is a must for teachers, whale and dolphin watchers, environmentalists, and ocean lovers everywhere.

Based on actual data of Soviet whaling, and reliable methodologies that existed at the time when this monograph was written, it examines the distribution and migration patterns of whales of the Southern Ocean. It defines distinct populations on the basis of phenes, as well as whale breeding zones, which are located in the adjacent to the Southern Ocean waters at lower latitudes. The book records the presence of a new species of killer whale in the Southern Ocean - Orcinus nana. Prenatal growth patterns, pregnancy and lactation duration, mean sizes of new-born whales are determined. Methods for the graphic recording of registering structures are described, and an original method for their decoding is proposed to determine animal age. The age of sexual and physical maturity, life expectancy is determined. Earlier unknown "pair formations" on the lower jaw of baleen whales and sperm whales are described, together with their macro, histological and electronic microscopic structure. The impact of the extermination of whales on the Southern Ocean ecosystem is examined, recommendations for control of the current state of whale populations are given, and perspectives of whale population recovery are estimated. Regions that could be used as testing areas for whale registration method are defined. The book is intended for biologist-cytologists, ecologists and other specialists interested in cetaceans, and for biology students.

The bears of the world are among the most studied, and most loved, of all wild creatures. From the polar bear of the Arctic to the grizzlies of Yellowstone and the black bears that roam our woodlands, bears never fail to delight the amateur naturalist or fascinate the scientific observer. Here, in a single volume, THE GREAT BEAR ALMANAC collects what is known about the world's bears, presenting in words, pictures, maps, and charts a complete factual compendium of bear knowledge. Virtually everything known about bears is touched upon in this remarkably entertaining book. Part I, "Bears in Their World, " discusses where bears are found throughout the world, with notes on population estimates and detailed maps. A full section on anatomy and physiology discusses distinguishing features among bear species, details on the skull, teeth, claws and other bear parts, how well bears hear and see, and much more. Another section investigates hibernation, intelligence, feeding, play, and other behavioral traits. Part II, "Bears in the Human World, " examines the wide range of ways in which bears and human beings intersect: bears in myth and religion, in art, literature, and film, and above all, in real life - bear attacks, human encroachment on bear habitat, governmental regulations on bears, trafficking in bear parts by poachers, a summary of current bear research, and much more. A concluding chapter looks at future prospects for the bears of the world, and offers guidelines for how all those who admire bears can help protect these great and majestic creatures.

The word raccoon is drawn from the Native American Algonquian language. Their term arakun roughly translates to "he who scratches with his hands." Anyone who has found a raccoon rummaging around in a once securely closed trash container can attest to how skillful raccoons are with their front paws. In fact, they have four times as many sensory receptors in their forepaw skin as they do in their hind-paws -- a ratio similar to that of human hands and feet. Samuel Zeveloff explores this trait and much more in his accessible natural history of raccoons.

Written with the general reader in mind, Raccoons presents detailed information on raccoon evolution, physical characteristics, social behavior, habitats, food habits, reproduction, and conservation, as well as their relationship with humans and many other topics. The section on distribution and subspecies focuses on the raccoon's current range expansion and the material on their cultural significance demonstrates this mammal's unique status in different North American cultures.

Raccoons includes 28 illustrations and is sure to become the standard work on this wide-ranging species.

A vivid exploration of the reintroduction of the Mexican wolf to the American Southwest. Lobos, or Mexican wolves, once roamed freely throughout Arizona, New Mexico, and Texas until they were hunted to extinction when big cattle interests came to the Southwest. Now, a Mexican wolf introduction - similar to the Yellowstone efforts for its cousin the gray wolf - is underway in Arizona. But cattle have overgrazed the fragile land, damaging the ecosystem that barely sustains their vast numbers. With literary talent and a naturalist's sensibility, Rick Bass examines the circumstances of the Mexican wolves. Part meditation, part probing journalism, The New Wolves is an important new chapter in the drama of wolves and the American West.

No wild animal captures the spirit of North America quite so powerfully as the wild horse - nor has any faced such diverse and potent enemies. In this provocative account, Hope Ryden - who helped to ensure the passage of the Wild and Free-Roaming Horse and Burro Act, which grants mustangs special protection - combs the history of these proud and noble horses. Descended from the Spanish horses riden by the conquistadors, they evolved into the tough and intelligent ponies that Indians - and later, explorers and cowboys - learned to rely on. From the period when wholesale extermination of the buffalo was underway until recent times, commercial and political interests have sought to eliminate the wild horses as varmints. In the latest update to this classic story, Ryden tells of the successes and failures in the last ten years of regulation, and has added stunning new color photographs. The subject of a front-page article in The New York Times when it was first published, America's Last Wild Horses continues to be a compelling testament to the life of a uniquely American symbol of grace and wildness, and is a must read for horse lovers and Western history enthusiasts everywhere.
