The general interest and attention paid to the use of the renewable natural resources of the world have increased greatly during the last decades. This is due to the environmental dilemma into which mankind has got itself by the total disregard of ecological facts and laws, the underprizing of natural resources and the overemphasis on economic develop ment, coupled with unimpeded rapid population growth and the preponderance of material istic consumption-oriented attitudes. The management and use of natural resources such as forests, grasslands, rivers and lakes were formerly considered purely in a financial context, whereas latterly, a consciousness of their social function and the indirect economic benefits which can be derived from them has developed. Thus, as regards these traditional resources, multi-use concepts comprising eco nomically oriented utilisation as well as recreational, educational and social use have be come widely accepted. Conservation of natural resources for sustainable consumptive as well as non-consumptive uses has been recognised as a key element for maintaining eco nomic development all over the world. Fortunately, the industrialised countries have started to apply this principle themselves and in their technical and financial aid to the developing Third World countries. This is manifest from policy documents such as the World Bank Policy on Development of Wild Lands, issued in 1987.

The preeminent guide to the world’s mammals is now enhanced with a dramatically expanded volume covering 19 orders, including such creatures as elephants, armadillos, and manatees. Since its first publication in 1964, Walker's Mammals of the World has become a favorite guide to the natural world for general readers and professionals alike. This new Walker's volume is a completely revised and updated compendium of information on five of the earliest clades to diverge from ancient mammal stock. Uniquely comprehensive in inimitable Walker's style, it incorporates a full account of every genus that has lived in the past 5,000 years. Every named species of each genus is listed in systematic order and accompanied by detailed descriptions of past and present range. This new edition includes • 500+ full-color images throughout • citations to more than 2,200 new references • extensive bioconservation data, with discussion of every species in an IUCN Red List threatened category This volume's thorough updates reflect 20 years of advances in our knowledge of taxonomy, ecology, behavior, life history, and conservation. Substantive changes to 100% of previously existing generic accounts, plus the addition of 17 entirely new generic accounts, double the information in the last edition on the 19 orders covered. The black-and-white illustrations of earlier editions have been replaced by over 500 superb new color images. Remaining true to Ernest P. Walker's vision, the text smoothly combines in-depth scholarship with a popular, readable style to preserve and enhance what the Washington Post called a "landmark of zoological literature."

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 hindpaws, 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.

Authoritative yet easy to use, Handbook of Mammals of the South-Central States will be a close companion of field biologists and a ready reference for the naturally curious. Containing a wealth of information about mammalian wildlife in Alabama, Arkansas, Georgia, Kentucky, Louisiana, Mississippi, and Tennessee, the book describes in detail ninety-five native mammals and eight introduced species that live in that region. The south-central United States is both diverse and complex ecologically, including within its range coastal and inland swamps, mountain peaks, forests, grasslands, sand dunes, and rich agricultural lands. In the books' introduction, the authors describe those environments--their physiography, drainage patterns, climates ,soils and vegetation--and explain how they determine which species can exist there. They also discuss other facts--such as geographical history, competition between species, and the effects of man--that determine which species actually do occur in a particular area. The authors furnish a checklist of the 103 mammals, arranged in phylogenetic sequence, with keys to identifying the orders, families, and species. An up-to-date account of each species follows, supplying details about the animal's distribution throughout the seven states; its physical description, including seize, color pattern, and features distinguishing it from related species; and its natural history, including preferred habitat, diet, activity patterns, resting or nesting sites, reproduction, and population densities. A photograph, distribution map, and list of selected references complete each account. Handbook of Mammals of the South-Central States is the first comprehensive guide to focus on this region's mammalian fauna. Students will appreciate its accessible format, glossary of terms, index to scientific and vernacular names of the mammals, and selected bibliography. Amateurs and professional naturalists alike will rely on it to identify mammals in the field, laboratory, and classroom.

Authoritative and engaging, this volume from the Walker's Mammals series focuses on marsupials, pouched animals whose unusual method of reproduction—between egg laying and placental birth—places them in a unique category among mammals. A comprehensive guide to the biology and distribution of marsupials, this book includes common and scientific names, size and physical traits, habitat and ecology, behavior and social interactions, reproduction, life span, and conservation. The text is coupled with illustrations from the collections of leading photographers and the world's greatest museums. An introduction by marsupial expert Christopher R. Dickman describes the evolution and current status of marsupials and reveals why they add so much intrigue to the natural world.
