From one of the world's leading authorities on animal behavior, the astonishing story of how the female brain drives the evolution of beauty in animals and humans Darwin developed the theory of sexual selection to explain why the animal world abounds in stunning beauty, from the brilliant colors of butterflies and fishes to the songs of birds and frogs. He argued that animals have "a taste for the beautiful" that drives their potential mates to evolve features that make them more sexually attractive and reproductively successful. But if Darwin explained why sexual beauty evolved in animals, he struggled to understand how. In A Taste for the Beautiful, Michael Ryan, one of the world's leading authorities on animal behavior, tells the remarkable story of how he and other scientists have taken up where Darwin left off and transformed our understanding of sexual selection, shedding new light on human behavior in the process. Drawing on cutting-edge work in neuroscience and evolutionary biology, as well as his own important studies of the tiny Tungara frog deep in the jungles of Panama, Ryan explores the key questions: Why do animals perceive certain traits as beautiful and others not? Do animals have an inherent sexual aesthetic and, if so, where is it rooted? Ryan argues that the answers to these questions lie in the brain--particularly of females, who act as biological puppeteers, spurring the development of beautiful traits in males. This theory of how sexual beauty evolves explains its astonishing diversity and provides new insights about how much our own perception of beauty resembles that of other animals. Vividly written and filled with fascinating stories, A Taste for the Beautiful will change how you think about beauty and attraction.

Get outside! A hands-on lab manual for instructors incorporating fieldwork into their courses on mammalogy. Mammals inhabit nearly every continent and every sea. They have adapted to life underground, in the frozen Arctic, the hottest deserts, and every habitat in-between. In Mammalogy Techniques Lab Manual-the only field manual devoted to training the next generation of mammalogists-biologist and educator James M. Ryan details the modern research techniques today's professionals use to study mammals wherever they are found. Ideal for any mammalogy or wildlife biology course, this clear and practical guide aids students by getting them outside to study mammals in their natural environments. Twenty comprehensive chapters cover skull and tooth identification, radio and satellite GPS tracking, phylogeny construction, mark and recapture techniques, camera trapping, museum specimen preparation, optimal foraging, and DNA extraction, among other topics. Each chapter includes several exercises with step-by-step instructions for students to collect and analyze their own data, along with background information, downloadable sample data sets (to use when it is not practical to be out in the field), and detailed descriptions of useful open-source software tools. This pragmatic resource provides students with real-world experience practicing the complex techniques used by modern wildlife biologists. With more than 60 applied exercises to choose from in this unique manual, students will quickly acquire the scientific skills essential for a career working with mammals.

This volume brings together some of the best known and respected experts in the field of marine mammal biology to provide a cohesive and accessible text. A very broad scope of topics and examples are classified as marine mammals; the whales, dolphins and porpoises (cetaceans), seals, sea lions, fur seals and walruses (pinnipeds), manatees and dugongs (sirenians), and the sea otter and polar bear (carnivores). Topics covered include diversity, distribution and evolutionary patterns, anatomical and physiological adaptations, vocal and social behaviour, problem solving and memory, feeding ecology and energetics, life history and reproductive strategies, patterns of movement and population genetics, and conservation and management. Chapters are fully cross-referenced and illustrated, and the citations are numerous and current. All chapters are united by the theme of evolutionary context, addressing the question of how these diverse mammalian species have adapted to life in the oceans. The intended audience includes students of marine biology, ecology and evolution, as well as professionals with an interest in marine mammals, evolutionary pattern and process, zoology and ecology.

"Mammoths, Sabertooths, and Hominids" takes us on a journey through 65 million years, from the aftermath of the extinction of the dinosaurs to the glacial climax of the Pleistocene epoch; from the rain forests of the Paleocene and the Eocene, with their lemur-like primates, to the harsh landscape of the Pleistocene Steppes, home to the woolly mammoth. It is also a journey through space, following the migrations of mammal species that evolved on other continents and eventually met to compete or coexist in Cenozoic Europe. Finally, it is a journey through the complexity of mammalian evolution, a review of the changes and adaptations that have allowed mammals to flourish and become the dominant land vertebrates on Earth.

With the benefit of recent advances in geological and geophysical techniques, Jordi Agust? and Mauricio Ant?n are able to trace the processes of mammalian evolution as never before; events that hitherto appeared synchronous or at least closely related can now be distinguished on a scale of hundreds or even dozens of thousands of years, revealing the dramatic importance of climactic changes both major and minor. Evolutionary developments are rendered in magnificent illustrations of the many extraordinary species that once inhabited Europe, detailing their osteology, functional anatomy, and inferred patterns of locomotion and behavior. Based on the latest research and field work, "Mammoths, Sabertooths, and Hominids" transforms our understanding of how mammals evolved and changed the face of the planet.

A remarkable achievement that took over 30 years to construct, Keys for Identifying Mexican Mammals is the only complete identification guide to Mexico's mammalian fauna. Fully updated and revised, this bestselling book follows a bilingual arrangement, with identical information presented in Spanish and English on facing pages. The dichotomous presentation is both easy to follow and flawlessly compiled, including updated and expanded material that surpasses any previously available resource. Hundreds of diagnostic images are dispersed throughout the book, many showing minute details that differentiate one species from another, and introductory materials carefully explain the use of diagnostic features. The heart of the book, though, is the keys themselves, which cover every taxa-from artiodactyls and carnivores to primates and rodents-while allowing confident identification at the species level for both field and museum use. The book closes with appendices that cover preparation of specimens, a glossary, and a bibliography. Anyone with an interest in the mammalian fauna of Mexico, or mammals in general, will find this one-of-a-kind book an indispensable reference to Mexico's rich diversity of wildlife.

"The Deer and the Tiger" is Schaller's detailed account of the ecology and behavior of Bengal tigers and four species of the hoofed mammals on which they prey, based on his observations in India's Kanha National Park.
"This book is a treasure house of biological information and it is also a delight to read. . . . Excellent phoographs accompany the text."--Robert K. Enders, "American Scientist"

It reveals startling information on feeding habitats, territorial behaviour, and the nuances that make up the language of the forest; you become totally immersed in the world of the tiger. . . . For all of us who work in tiger conservation, this book is "the" bible."--Valmik Thapar, "BBC Wildlife"

With more than two hundred species distributed across most of mainland Mexico, Central and South America, and islands in the Caribbean Sea, the Phyllostomidae bat family (American leaf-nosed bats) is one of the world's most diverse mammalian families in terms of its trophic, or feeding, diversity. From an insectivorous ancestry, extant species have evolved into several dietary classes, including blood-feeding, vertebrate carnivory, and the consumption of nectar, pollen, and fruit, in a period of about 30 million years. Phyllostomidae's plant-visiting species are responsible for pollinating more than five hundred species of neotropical shrubs, trees, vines, and epiphytes--many of which are economically and ecologically important--and they also disperse the seeds of at least another five-hundred plant species. Fruit-eating and seed-dispersing members of this family thus play a crucial role in the regeneration of neotropical forests, and the fruit eaters are among the most abundant mammals in these habitats. Coauthored by leading experts in the field and synthesizing the latest advances in molecular biology and ecological methods, Phyllostomid Bats is the first overview in more than forty years of the evolution of the many morphological, behavioral, physiological, and ecological adaptations in this family. Featuring abundant illustrations as well as details on the current conservation status of phyllostomid species, it is both a comprehensive reference for these ecologically vital creatures and a fascinating exploration of the evolutionary process of adaptive radiation.

Because of its climatic and topographic variability, KwaZulu-Natal is extremely rich in fauna, containing over one half of all the smaller mammals of the entire southern African subregion. The scientific text covers the lesser known small mammals of this region including rodents, shrews, bats, elephant shrews, hares, primates, dassies and the aardvark and pangolin. The book includes 103 species accounts, 105 accompanying distribution maps and 48 color plates.

In this text, nine new species of small mammals are described from this province for the first time. This text is the definitive resource on the smaller mammals of KwaZulu-Natal.

In nature, the ability to defend against predators is fundamental to an animal's survival. From the giraffes that rely on their spotted coats to blend into the patchy light of their woodland habitats to the South American sea lions that pile themselves in heaps to ward off the killer whales that prey on them in the shallow surf, defense strategies in the animal kingdom are seemingly innumerable.
In "Antipredator Defenses in Birds and Mammals," Tim Caro ambitiously synthesizes predator defenses in birds and mammals and integrates all functional and evolutionary perspectives on antipredator defenses that have developed over the last century. Structured chronologically along a hypothetical sequence of predation--Caro evokes a gazelle fawn desperate to survive a cheetah attack to illustrate the continuum of the evolution of antipredator defenses--"Antipredator Defenses in Birds and Mammals" considers the defenses that prey use to avoid detection by predators; the benefits of living in groups; morphological and behavioral defenses in individuals and groups; and, finally, flight and adaptations of last resort.
"Antipredator Defenses in Birds and Mammals" will be of interest to both specialists and general readers interested in ecological issues.

The giant panda is one of the world's most recognized animals. With the environment undergoing unprecedented change at a rapid and accelerating rate, can such a highly specialized species survive? This 2006 book summarizes panda biology and encompasses topics such as reproduction, behaviour, nutrition, genetics and veterinary medicine. It also provides information on veterinary management, advances in neonatal care, disease detection and prevention and the use of 'assisted breeding' to promote reproduction and preserve genetic diversity, as the females are sexually receptive for only 3 days per year and generally produce twins, but often lose one due to maternal neglect. This book provides the scholarly knowledge that will help conserve this treasured species in nature, while there is still time.

The book ventures to look into eras bygone in order to chronicle the passage of three mega species-the rhinoceros, tiger, and elephant across millennia in early north India. It carefully sifts through an archive comprising faunal remains and visual depictions retrieved from the archaeological record as well as a gamut of Sanskrit, Pali, Prakrit, and classical Western accounts to document the presence of these big mammals in various cultural niches from hunter-gatherer societies to the first urban civilization of India and beyond. The narrative goes beyond treating these species as mere cultural icons to one that is also sensitive to their importance as markers of ecology. The focus is two-fold: to comprehend perceptions, attitudes, and sensibilities oscillating between veneration and persecution in order to reconstruct the cultural dimensions of human-megafaunal relations in the past, as also to use these species to understand the larger ecology of ancient India. At a time when the conservation of our megafaunal heritage is a major concern for biologists, ecologists as well as conservationists, this book underlines the need to historicize human interactions with these mega mammals keeping in mind that an animal's past is critical in thinking about its future.

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."

This book provides a comprehensive review of the evolution of traits associated with predation and predator defense for bats and all of their prey, both invertebrates (e.g. insects) and vertebrates (e.g. frogs), in the context of co-evolution. It reviews current knowledge of how echolocation and passive hearing are used by bats to hunt prey in complete darkness. Also it highlights how prey have evolved counter measures to bat echolocation to avoid detection and capture. This includes the whole range of prey responses from being active at times when bats are inactive to the use of acoustic signals of their own to interfere with the echolocation system of bats.

Edward G. Jones??? The Thalamus is one of the most cited publications in neuroscience. Now more than 20 years on from its first printing, the author has completely rewritten his landmark volume, incorporating the numerous developments in research and understanding of the mammalian thalamus. As a leading authority on thalamus biology and function, Edward G. Jones shows how knowledge of the thalamus has developed with the introduction of new technologies and ideas. The author's photographic skills are exhibited in brilliant preparations of thalamic structure in a wide range of common and uncommon species. The Thalamus is both an up-to-date scientific review of virtually all aspects of forebrain function and a work of immense neuroscientific scholarship. It forms an essential reference for neuroanatomists, neurophysiologists, molecular neurobiologists, developmental neurobiologists and clinicians its deep historical perspective will be of value to historians of science.

Humans share a long history with carnivores. We fear them as predators, revile them as competitors, exploit them for their fur, or admire them for their grace and beauty.

This book will be an important educational reference for the general public, schools, naturalists and wildlife biologists.

This atlas presents a series of photographic illustrations and line drawings that summarize the major developmental events that occur during organogenesis in the opossum (Didelphis virginiana).It will be of interest to General Biologists, Zoologists, Wildlife Biologists, Embryologists and Medical Scientists.

Since early on in the development of wind-energy production, concerns have arisen about the potential impacts of turbines to wildlife; these concerns have especially focused on the mortality of birds. Structural changes and improved turbine design have been instrumental in reducing mortality in birds. Despite the improvements to turbines that have resulted in reduced mortality of birds, there is clear evidence that bat mortality at wind turbines is of far greater conservation concern. Larger and taller turbines actually seem to be causing increased fatalities of bats. Numerous research opportunities exist that pertain to issues such as identifying the best and worst placement of sites for turbines; and mitigation strategies that would minimise impacts to wildlife (birds and bats). This book focuses on refereed journal publications and theses about bats and wind-energy development in North America.
