Bats are fascinating mammals about which we still have much to learn. As well as using ultrasonic echolocation calls for orientation and while foraging, they also have a complex array of vocalisations for communication. These are known as social calls and are an essential component of their colonial lifestyle. This book brings together the current state of knowledge of social calls relating to the bat species occurring within Britain and Ireland, with some additional examples from species represented elsewhere in Europe. It includes access to a downloadable library of calls to be used in conjunction with the book. Downloadable call library Social calls are complex and intriguing to listen to; they are after all produced with listeners in mind (other bats). To enjoy and fully appreciate social calls the reader must also have the opportunity to become a listener: each of the presented sonograms in the book is cross-referenced to downloadable 'time expanded' .wav sound files which are contained within a much wider library of calls for you to explore. Included in Social Calls of the Bats of Britain and Ireland The authors start with an overview of the species of bats in Britain and Ireland (Chapter 1), and then introduce us to communication within the social world of bats (Chapter 2). Referencing the latest research, the authors explore how these calls can be classified according to their structure, and in many cases the context in which the calls are thought to be emitted (Chapter 3). Chapter 4 addresses aspects of survey methodology to be considered by those studying social calls. This leads on to the analysis of calls (Chapter 5), detailing the specific methods used and parameters commonly measured by researchers. The final, and main chapter (Chapter 6) introduces the 23 species covered in the book giving each a detailed profile including: habitat preferences, typical roosting locations, roost emergence times, mating strategies and maternity behaviour. Each species profile includes what is known about the social calls for that species and this text is supported by colour sonograms (created using Pettersson BatSound V4.1) of most of the calls discussed. Each sonogram is linked to a .wav sound file (Time Expansion x10) within the downloadable library. The sound files allow the reader to hear, as well as see, the calls produced using any bat sound analysis software that supports the .wav format. The authors conclude with a bibliography and an extensive list of references directly cross-referenced throughout the book.

This valuable collection of essays presents and evaluates techniques of body-mass estimation and reviews current and potential applications of body-size estimates in paleobiology. Papers discuss explicitly the errors and biases of various regression techniques and predictor variables, and the identification of functionally similar groups of species for improving the accuracy of estimates. At the same time other chapters review and discuss the physiological, ecological, and behavioral correlates of body size in extant mammals; the significance of body-mass distributions in mammalian faunas; and the ecology and evolution of body size in particular paleofaunas. Coverage is particularly detailed for carnivores, primates, and ungulates, but information is also presented on marsupials, rodents, and proboscideans.

From the raucous mantled howler monkeys and the charismatic white-nosed coatis to the elusive jaguar, The Mammals of Costa Rica offers authoritative accounts of the fascinating creatures of the neotropics. With more than four hundred spectacular illustrations and a wealth of detailed information drawn from firsthand observation, new research, and synthesis of the scientific literature, this book describes all of Costa Rica's readily identifiable terrestrial and freshwater mammals. The clear and entertaining text is perfectly suited to meet the needs of naturalists, students, and researchers, as well as both experienced and first-time visitors to Costa Rica and the American tropics. The mammal descriptions include key identification features, range maps, vocalizations, local folklore and mythology, and comprehensive information about natural history and conservation. The color illustrations show not only the mammals themselves but also their tracks, foods, and skulls. Also included are illustrations of numerous other animals and plants with which the mammals have close ecological links. By presenting mammals in a broader context, The Mammals of Costa Rica provides an entry point into a general study of tropical ecology and conservation.

Growing human populations and higher demands for water impose increasing impacts and stresses upon freshwater biodiversity. Their combined effects have made these animals more endangered than their terrestrial and marine counterparts. Overuse and contamination of water, overexploitation and overfishing, introduction of alien species, and alteration of natural flow regimes have led to a 'great thinning' and declines in abundance of freshwater animals, a 'great shrinking' in body size with reductions in large species, and a 'great mixing' whereby the spread of introduced species has tended to homogenize previously dissimilar communities in different parts of the world. Climate change and warming temperatures will alter global water availability, and exacerbate the other threat factors. What conservation action is needed to halt or reverse these trends, and preserve freshwater biodiversity in a rapidly changing world? This book offers the tools and approaches that can be deployed to help conserve freshwater biodiversity.

What parent hasn't wondered "What do I do now?" as a baby cries or a teenager glares? Making babies may come naturally, but knowing how to raise them doesn't. As primatologist-turned-psychologist Harriet J. Smith shows in this lively safari through the world of primates, parenting by primates isn't instinctive, and that's just as true for monkeys and apes as it is for humans. In this natural history of primate parenting, Smith compares parenting by nonhuman and human primates. In a narrative rich with vivid anecdotes derived from interviews with primatologists, from her own experience breeding cotton-top tamarin monkeys for over thirty years, and from her clinical psychology practice, Smith describes the thousand and one ways that primate mothers, fathers, grandparents, siblings, and even babysitters care for their offspring, from infancy through young adulthood. Smith learned the hard way that hand-raised cotton-top tamarins often mature into incompetent parents. Her observation of inadequate parenting by cotton-tops plus her clinical work with troubled human families sparked her interest in the process of how primates become "good-enough" parents. The story of how she trained her tamarins to become adequate parents lays the foundation for discussions about the crucial role of early experience on parenting in primates, and how certain types of experiences, such as anxiety and social isolation, can trigger neglectful or abusive parenting. Smith reveals diverse strategies for parenting by primates, but she also identifies parenting behaviors crucial to the survival and development of primate youngsters that have stood the test of time.

Nearly half the world's primate species use flooded habitats at one time or another, from swamp-going Congo gorillas and mangrove-eating proboscis monkeys, to uacaris in Amazonian riverside forests. This first-ever volume on the subject brings together experts from around the world in a ground breaking volume spanning fossil history, current biology and future research and conservation priorities. Flooded habitats are a vital part of tropical biology, both for the diversity of the species they house, and the complexity of their ecological interactions, but are often completely overlooked. This book will set the stage for a new wave of research on primates in these extraordinarily productive and highly threatened areas, and is ideal for researchers and graduate students in primatology, zoology, ecology, and conservation.

Colombia is a one of the most biologically diverse countries in the world: although it takes up slightly less than one percent of the Earth's surface, it is home to approximately ten percent of the world's plants and animals, with a rich variety of flora and fauna and a diversity of primate species that is only superseded by Brazil and Peru in number. This vibrantly illustrated field guide is the result of a wealth of field work conducted on Colombian primates both in and out of the country.
The volume illustrates and describes twenty-eight primate species comprising forty-three taxa, of which fifteen taxa are only found in Colombia. The field guide also includes comprehensive chapters on primate classification, fossil history, and conservation, and each is augmented by a wealth of finely detailed drawings, photographs, and maps. "Primates of Colombia" will be an invaluable resource for primatologists and naturalists alike.
