The diminishing population of African and Asian elephants can be compared to the extinction of other elephant-like species, such as mammoths and mastodonts, which occurred more than ten thousand years ago. The purpose of this book is to use the ecology and behavior of modern elephants to create models for reconstructing the life and death of extinct mammoths and mastodonts. The source of the models is a long-term and continuing study of elephants in Zimbabwe, Africa. These models are clearly described with respect to the anatomical, behavioral, and ecological similarities between past and present proboscideans. The implications of these similarities on the life and death of mammoths and mastodonts is explored in detail. The importance of this book is primarily its unifying perspective on living and extinct proboscideans: the fossil record is closely examined and compared to the natural history of surviving elephants. Dr. Haynes's studies of the places where African elephants die (so-called elephant burial grounds) are unique.

The largest land mammals are constrained in their activities by their large body size, a theme that is emphasized in this account of their general ecology. The book begins by raising the question as to why these once abundant and widely distributed 'megaherbivores' - elephants, rhinos, hippos and giraffes - have all but gone extinct, and ends by considering the implications of the answer for the conservation of the remaining populations. Existing megaherbivores are placed in the context of the more numerous species which occurred worldwide until the end of the last Ice Age, and knowledge of the ecology of surviving species is used to analyse the cause of the extinctions. The information and ideas contained in this book are of crucial importance to all concerned with halting the rapidly worsening conservation status of remaining elephant and rhinoceros species, and carries a wider message for those concerned with the ramifying effects of man on ecosystem processes. Graduate students and research scientists in ecology, conservation biology and wildlife management will find this book of value.

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.

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.

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.
