Book Description
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.

Book Description
Although they are highly intelligent, ruthless predators, carnivores are increasingly rare. From the dwarf mongoose to the polar bear, carnivores are at once respected and misunderstood, invoking both fear and curiosity in the humans with whom they share their world. Ronald M. Nowak celebrates these fascinating mammals in Walker's Carnivores of the World. This comprehensive guide, featuring 225 illustrations, covers the world's eight terrestrial families of carnivores. Each generic account comprises scientific and common names, number and distribution of species, physical attributes, measurements, hunting and social activity, reproduction, habitat, population dynamics, longevity, and status of threatened species. A thought-provoking overview by David W. Macdonald and Roland W. Kays is packed with results of the latest field and laboratory research on topics ranging from evolutionary history to the adaptive value of fur patterns. Emphasizing the interplay of social life, morphology, and predatory behavior, it provides an up-to-date panorama of the world's carnivores.

Book Description
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."

Book Description
Did you know . . . ? Michigan is seventeenth in oil production in the United States. The Great Lakes are said to be the only glacially produced structures that can be seen from the moon. Michigan was once part of a coral reef. The wood frog is one of the commonest true frogs of moist woodland floors in Michigan today and is able to freeze solid during the winter without harmful effects. These and many more amazing facts await the curious traveler in The Michigan Roadside Naturalist, J. Alan and Margaret B. Holman's captivating guide to the natural treasures of Michigan. A perfect accompaniment to the classic Michigan Trees and The Forests of Michigan, this user-friendly guide offers a Who's Who of the geology, biology, and archaeology of the Great Lakes State, as well as highway adventures along the state's major routes. The book begins with an educational yet accessible tour of important points in Michigan's natural and archaeological history, followed by seven road trips based on commonly traveled state routes, moving from south to north in the Lower Peninsula and east to west in the Upper Peninsula. Readers can proceed directly to the road trips or familiarize themselves with the state's treasure trove of fascinating features before embarking. Either way, an informative and fun odyssey awaits the passionate naturalist, amateur or otherwise. J. Alan Holman is Curator Emeritus of Vertebrate Paleontology at the Michigan State University Museum and Emeritus Professor of Geology and Zoology at Michigan State University. Margaret B. Holman is Research Associate at Michigan State University Museum and Department of Anthropology, Michigan State University.
