The best field guide to North American mammals The best-selling field guide that "sets new standards" (New Scientist) and "makes all other field guides for mammals of the United States. . . and Canada obsolete" (Journal of Mammalogy) is now even better. Covering 20 species recognized since 2002 and including 13 new color plates, this fully revised edition of Mammals of North America illustrates all 462 known mammal species in the United States and Canada—each in beautiful color and accurate detail. With a more up-to-date species list than any other guide, improved facing-page descriptions, easier-to-read distribution maps, updated common and scientific names, and track and scat illustrations, this slim, light, and easy-to-use volume is the must-have source for identifying North American mammals. Roland Kays and Don Wilson have scoured the technical literature to pull out the key differences between similar species, and illustrated these whenever possible, making the guide useful to amateur naturalists and professional zoologists alike. Casual animal watchers will appreciate the overview of mammal diversity and the tips on identifying animals they can spy in their binoculars, while scientists will appreciate the exacting detail needed to distinguish similar species, including illustrations of shrew teeth, bat toes, and whale dorsal fins. The best-illustrated and easiest-to-use field guide to North American mammals Beautiful and accurate color illustrations of all 462 mammals found in the United States and Canada—including 20 species recognized since 2002 112 color plates—including 13 new ones Key identification information—fully revised—on facing pages The most current taxonomy/species list Fully revised, easy-to-read range maps Illustrations of tracks, scat, and whale and dolphin dive sequences

From the calling macaw and the roaring lion to the dancing lyrebird, animals all around us can be heard and seen communicating with each other and, occasionally, with us. Why they do so, what their utterances mean, and how much we know about them are the subject of Songs, Roars, and Rituals. This is a concise, yet comprehensive, introduction to the complexities of communication in animals. Rogers and Kaplan take us on an exciting journey through communication in the animal world, offering insights on how animals communicate by sight, sound, smell, touch, and even electrical signaling. They explore a wide variety of communication patterns in many species of mammals and birds and discuss in detail how communication signals evolved, how they are learned, and what song and mimicry may mean. An up-to-date account of the science of animal communication, this book also considers modern concepts (such as that of deceptive communication) and modern controversies, primarily those surrounding the evolution of human language and the use of symbolic language by apes. It concludes with a thought-provoking look at the future of communication between humans and animals.

A groundbreaking argument on how endothermy--arguably the most important innovation in vertebrate evolution--developed in birds and mammals "Vividly narrated and illustrated. . . . Provocative and fascinating for specialists and lay readers alike."--Southeastern Naturalist This pioneering work investigates why endothermy, or "warm-bloodedness," evolved in birds and mammals, despite its enormous energetic costs. Arguing that single-cause hypotheses to explain the origins of endothermy have stalled research since the 1970s, Barry Gordon Lovegrove advances a novel conceptual framework that considers multiple potential causes and integrates data from the southern as well as the northern hemisphere. Drawing on paleontological data; research on extant species in places like the Karoo, Namaqualand, Madagascar, and Borneo; and novel physiological models, Lovegrove builds a compelling new explanation for the evolution of endothermy. Vividly narrated and illustrated, this book stages a groundbreaking argument that should prove provocative and fascinating for specialists and lay readers alike.

Hibernation and Torpor in Mammals and Birds explores the physiological factors that control hibernation and torpor in birds and mammals. This text covers topics ranging from metabolism in hibernation to the role of endocrines, respiration and acid-base state in hibernation, and theories of hibernation. This book is comprised of 14 chapters and begins with an overview of some clear-cut definitions and why mammals and birds hibernate. The reader is then introduced to the variations from euthermia that have been observed among birds and mammals. To give some structure to this listing, the approach is phylogenetic, starting with the birds and proceeding through the primitive to the more advanced mammals. Subsequent chapters explains the process of entering hibernation and the hibernating state, itself; capability of a species in natural hibernation to arouse from that state using self-generated heat; physiological changes at the start of a spontaneous arousal; and physiological mechanisms underlying the ability of hibernators to rewarm. Consideration is also given to intermediary metabolism in hibernation, cold adaptation of metabolism in hibernators, and the response of hibernators to various extrinsic influences such as neoplastic growth, radiation injury, and parasitism and symbionts. This book will be of interest to students and researchers in fields ranging from zoology to physiology and biophysics.

An indispensable color-illustrated field guide to the tracks and signs of Europe's animals and birds This beautifully illustrated field guide enables you to easily identify the tracks and signs left by a wide variety of mammal and bird species found in Britain and Europe, covering behaviors ranging from hunting, foraging, and feeding to courtship, breeding, and nesting. Introductory chapters offer detailed drawings of footprints and tracks of large and small mammals, which are followed by sections on mammal scat, bird droppings, and the feeding signs of animals on food sources such as nuts, cones, and rose hips. The book then describes specific mammal species, providing information on size, distribution, behavior, habitat, and similar species, as well as more specific detail on tracks and scat. Distribution maps are also included. This indispensable field guide covers 175 species of mammals and birds, and features a wealth of stunning color photos and artwork throughout. Helps you easily identify the tracks and signs of a variety of mammals and birds Covers 175 species Illustrated throughout with photos, drawings, and artwork Includes informative descriptions of mammal species along with distribution maps
