How intelligent are dolphins? Is their communication system really as complex as human language? And are they as friendly and peaceful as they are made out to be? The Western world has had an enduring love affair with dolphins since the early 1960s, with fanciful claims of their 'healing powers' and 'super intelligence'. Myths and pseudoscience abound on the subject. Justin Gregg weighs up the claims made about dolphin intelligence and separates scientific fact from fiction. He puts our knowledge about dolphin behaviour and intelligence into perspective, with comparisons to scientific studies of other animals, especially the crow family and great apes. He gives fascinating accounts of the challenges of testing what an animal with flippers and no facial expressions might be animal behaviour, Gregg challenges many of the widespread beliefs about dolphins, while also inspiring the reader with the remarkable abilities common to many of the less glamorized animals around us - such as chickens.

Muntjac and water deer were introduced to Britain from East Asia. This book provides a comprehensive overview of their natural history and the management of their environmental impacts. In lowland England, muntjac deer are one of the drivers of changes in woodland structure and species composition, and many of the principles relating to such woodland impact are also applicable to the activities of other species of deer. Interest in environmental impacts of deer is not solely restricted to woodlands. The highest densities of water deer occur in wetlands, where there is potential for conflict, and considerable numbers are also found on agricultural land. Muntjac have also settled in suburbia and frequently cause impacts there. Conservationists and national decision makers are concerned both about invasive alien species and about increasing deer populations. The first section covers the natural history of both species including: breeding biology, deer in the field, colonisation of Britain, a detailed look at colonisation in a single county, methods for studying deer populations and a review of deer population numbers. The second section covers environmental impact: risk assessment, impact management, control of muntjac, effect of muntjac browsing and grazing, habitat recovery from muntjac impacts and a study on the impacts of water deer. The section concludes with an overview of management and monitoring. The costs and benefits of both species are discussed, and questions asked about whether we are getting on top of problems caused by muntjac (locally and nationally) and will water deer turn out to be similar to muntjac? Attitudes and approaches to these species are changing: with water deer we are actively studying whether it might be an environmental problem, not waiting until after it has obviously become one. What will happen to distribution, numbers, impacts and attitudes in the future? Will water deer ever become a suburban animal? What does the future hold for water deer in China and Korea - and how important is the English population as a global conservation resource?

Savannah habitats comprise an ecologically important, but ultimately fragile, ecosystem. They constitute one of the largest biomes on Earth, covering almost 20% of the land surface, and can be simply described as tropical and subtropical grasslands with scattered bushes and trees. Most savannahs occur in Africa, although smaller areas can be found in South America, India, and Australia. They form a rich mosaic of diverse ecosystems, and this book offers a concise but comprehensive introduction to their ecology, biodiversity, and conservation. The Biology of African Savannahs describes the major plants (grasses, and trees such as Acacia) and animals (mainly large mammals) that live in this habitat, and examines the biological and ecological factors that influence their population size, interactions (such as predation), and community composition. Conservation issues such as climate change, hunting, and conflict between wildlife and domestic animals are also discussed. This new edition has been updated throughout with the latest research in the field, and contains new technique boxes which introduce readers to some of the analytical methods used to study African savannahs. This accessible text is suitable for both senior undergraduate and graduate students taking courses in savannah and tropical ecology as part of a wider ecology and/or conservation biology degree programme. It will also be of relevance and use to the many professional ecologists and conservation practitioners requiring a concise but authoritative overview of the topic.

In The Vestibular System: A Sixth Sense, leading experts present an integrative, comprehensive and innovative look at the sense that Aristotle missed. The vestibular system plays a vital role in everyday life, contributing to a surprising range of functions from reflexes to the highest levels of perception and consciousness. This text not only offers a thorough and fresh review of the basic sensory transduction, the neurophysiology of peripheral and central pathways and how vestibular signals are processed in the control of gaze and posture; it significantly moves the discussion forward with its attention to the current research and the field's revolutionary advances, such as the understanding of neural correlates of self-motion and the basis of clinical disorders. In addition, the objective presentation of existing controversies is exciting reading and an extremely important contribution to the text's completeness. Dynamic, intellectually challenging, and unique in its level of integration of the material, this book is essential for anyone interested in understanding the vestibular system.

Covering the behavior and ecology of the northern fur seal, this book is a model long-term study of marine mammals, one that tests theory through both observation of undisturbed behavior and manipulative experiments on individuals. Here Roger Gentry draws on nearly two decades of research on three different islands to show how behavior among these seals changes with population size, sex ratio, and environment, to explain the behavior of the population beginning with individuals, and to generalize the results to other members of the eared seal family. In so doing, he offers one of the most comprehensive studies of its kind on any marine mammal species to date.

Gentry shows that the species is driven by very different behavioral traits than have been assumed for it in the past. His book analyzes behavior on scales of hours to lifetimes, investigates the mating system, considers processes that underlie the mating system (site fidelity, behavioral estrus, and the development of territoriality), and addresses specific aspects of maternal strategy (female attendance behavior, pup growth, seasonal influences, and the effects of continental shelf width). Gentry contributes to knowledge about marine mammals by providing a very specific basis for interspecies comparisons, and he suggests a link between population trend and environmental regime shifts. He also guides the debate over seal mating systems from an interpretive to an empirical or experimental basis.

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.

The cheetah, the fastest terrestrial animal, has widespread appeal amongst wildlife biologists and enthusiasts alike. However, like all all large carnivores, it is increasingly threatened by habitat loss and its status is now classified as 'Vulnerable' by the IUCN. This is the first comprehensive study of cheetah biology in an arid environment, a major component of its current distribution range. The book brings together results from an intensive six year study of the cheetah by the authors in the Kgalagadi Transfrontier Park in South Africa and Botswana. It documents a wealth of detailed and direct observations of cheetah population biology and behavioural ecology, adopting an evolutionary approach and providing a conceptual framework for future research and applied management in the context of global environmental change. Kalahari Cheetahs covers topics such as optimal foraging theory, hunting strategies and predator prey relations, mating systems and reproductive strategies and success, inter-specific competition, demography, social organisation, and population limitation. Comparisons with previous cheetah studies reveal the variability of ecological determinants on behaviour, and the behavioural flexibility and ability of these carnivores to adapt to different environments. This advanced textbook is suitable for graduate level students as well as professional researchers in felid behavioural ecology and conservation biology. It will also be of relevance and use to conservationists, wildlife managers, and African wildlife enthusiasts.

Monkey see, monkey do may sound simple, but how an individual perceives and processes the behavior of another is one of the most complex and fascinating questions related to the social life of humans and other primates. In "The Primate Mind," experts from around the world take a bottom-up approach to primate social behavior by investigating how the primate mind connects with other minds and exploring the shared neurological basis for imitation, joint action, cooperative behavior, and empathy.

In the past, there has been a tendency to ask all-or-nothing questions, such as whether primates possess a theory of mind, have self-awareness, or have culture. A bottom-up approach asks, rather, what are the underlying cognitive processes of such capacities, some of which may be rather basic and widespread. Prominent neuroscientists, psychologists, ethologists, and primatologists use methods ranging from developmental psychology to neurophysiology and neuroimaging to explore these evolutionary foundations.

A good example is mirror neurons, first discovered in monkeys but also assumed to be present in humans, that enable a fusing between one s own motor system and the perceived actions of others. This allows individuals to read body language and respond to the emotions of others, interpret their actions and intentions, synchronize and coordinate activities, anticipate the behavior of others, and learn from them. The remarkable social sophistication of primates rests on these basic processes, which are extensively discussed in the pages of this volume.

Providing a comprehensive account of marine conservation, this book examines human use and abuse of the world's seas and oceans and their marine life, and the various approaches to management and conservation. Healthy marine ecosystems - the goods and services that they provide - are of vital importance to human wellbeing. There is a pressing need for a global synthesis of marine conservation issues and approaches. This book covers conservation issues pertinent to major groups of marine organisms, such as sharks, marine turtles, seabirds and marine mammals; key habitats, from estuaries, wetlands and coral reefs to the deep sea; and from local and regional to international initiatives in marine conservation. An ideal resource for students, researchers and conservation professionals, the book pays appropriate attention to the underlying marine biology and oceanography and how human activities impact marine ecosystems, enabling the reader to fully understand the context of conservation action and its rationale.

Based on field studies spanning nearly 40 years, this reference book summarizes and integrates past research with new and previously unpublished information on the behavioral ecology of Africa's red colobus monkeys from study sites as diverse as Senegal, Uganda and Zanzibar. It provides an unparalleled compilation of information on taxonomy, genetics, vocalizations, demography, social organization, dispersal, social behavior, reproduction, mortality factors, diet, ranging patterns, interspecific relations, and conservation. Social relationships in red colobus are less rigidly structured than in other African monkeys, resulting in considerable variation in social organization and group composition, both within and between taxa. This provides a unique opportunity to examine the extent to which social variables correlate with differences in habitat quality, demography, and predation by chimpanzees and humans. Unfortunately, at least half of the 18 taxa of red colobus are now threatened with extinction. Conservation problems are described, causal factors identified, and solutions proposed. This volume is intended not only to serve as a reference book, but to stimulate and guide future long-term research and to encourage effective conservation action.

This book describes one of our closest relatives, the orangutan, and the only extant great ape in Asia. It is increasingly clear that orangutan populations show extensive variation in behavioural ecology, morphology, life history, and genes. Indeed, on the strength of the latest genetic and morphological evidence, it has been proposed that orangutans actually constitute two species which diverged more than a million years ago - one on the island of Sumatra the other on Borneo, with the latter comprising three subspecies.
This book has two main aims. The first is to carefully compare data from every orangutan research site, examining the differences and similarities between orangutan species, subspecies, and populations. The second is to develop a theoretical framework in which these differences and similarities can be explained. To achieve these goals the editors have assembled the world's leading orangutan experts to rigorously synthesize and compare the data, quantify the similarities or differences, and seek to explain them.
Orangutans is the first synthesis of orangutan biology to adopt this novel, comparative approach. It analyses and compares the latest data, developing a theoretical framework to explain morphological, life history, and behavioural variation. Intriguingly, not all behavioural differences can be attributed to ecological variation between and within the two islands; relative rates of social learning also appear to have been influential. The book also emphasizes the crucial impact of human settlement on orangutans and looks ahead to the future prospects for the survival of critically endangered natural populations.

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.

Analysing the physiological adaptations of marine mammals and seabirds, this book provides a comprehensive overview of what allows these species to overcome the challenges of diving to depth on a single breath of air. Through comparative reviews of texts on diving physiology and behaviour from the last seventy-five years, Ponganis combines this research into one succinct volume. Investigating the diving performance of marine mammals and seabirds, this book illustrates how physiological processes to extreme hypoxia and pressure are relevant to the advancement of our understanding of basic cellular processes and human pathologies. This book underscores the biomedical and ecological relevance of the anatomical, physiological and molecular/biophysical adaptations of these animals to enable further research in this area. An important resource for students and researchers, this text not only provides an essential overview of recent research in the field, but will stimulate further research into the behaviour and physiology of diving.

Despite an astonishing 100 million-fold range in adult body mass from bumblebee bat to blue whale, all mammals are formed of the same kinds of molecules, cells, tissues and organs and to the same overall body plan. A scaling approach investigates the principles of mammal design by examining the ways in which mammals of diverse size and taxonomy are quantitatively comparable. This book presents an extensive reanalysis of scaling data collected over a quarter of a century, including many rarely or never-cited sources. The result is an unparalleled contribution to understanding scaling in mammals, addressing a uniquely extensive range of mammal attributes and using substantially larger and more rigorously screened samples than in any prior works. An invaluable resource for all those interested in the 'design' of mammals, this is an ideal resource for postgraduates and researchers in a range of fields from comparative physiology to ecology.

A topic of perpetual fascination, the kangaroos of Australia have been the focus of myriad books and documentaries. "Kangaroos in Outback Australia" focuses on Yathong Nature Reserve, where three species of kangaroo -- red, eastern grey, and western grey -- overlap and create a unique opportunity for ecological study.

Dale and Yvette McCullough spent fifteen months in Yathong examining the comparative ecology and behavior of the different species. The McCulloughs used systematic counts, radio telemetry, direct observations, and other techniques to characterize and compare the different species' population sizes, home ranges and movements, activity patterns, habitat selection, feeding behavior, and social organization.

The researchers' previous work on the kangaroos' closest ecological counterparts in North America, the white-tailed and the mule deer, serves as a subject for comparison and enlarges the overall scope of the work.

Do you think identifying bats in Europe or in North America is difficult? Well, try it in the Amazon. The planet's green lung is home to the most diverse bat communities on the planet with more than 160 species currently described. Local species richness often surpasses 100 and for many, their identification in the field is, to say the least, challenging. This task will now become easier with the publication of the Field Guide to the Bats of the Amazon: a landmark handbook aimed at facilitating species identification in the field. The book, written and designed by an international bat research team mainly based in the University of Lisbon in collaboration with the National Institute of Amazonian Research (INPA), is a guide for anyone conducting field work on bats in the Amazon or interested in bat biodiversity. It is largely based on previous published keys with modifications derived from both personal observations and years of field experience in the Brazilian Amazon at the Biological Dynamics of Forest Fragments Project (BDFFP), as well as a thorough revision of available bat keys and species descriptions. The field guide also features the first acoustic key for Amazonian bats, illustrated with the echolocation spectrogram of most species. This represents a major step towards alleviating the daunting task of identifying the numerous species of aerial insectivorous bats that occur in the Amazon based on their echolocation calls. It further constitutes an important tool to improving the knowledge and optimizing surveys of aerial insectivorous Neotropical bats, a group which remains largely understudied. The field guide provides an essential tool, not only for researchers, but also for bat conservationists, consultancies and anyone interested in Neotropical bats in general, and Amazonian bats in particular.

Every three years a major international conference on bats draws the leading workers in the field to a carefully orchestrated presentation of the research and advances and current state of understanding of bat biology. Bats are the second most populous group of mammalia species, after rodents, and they are probably the most intensively studied group of mammals. Virtually all mammologists and a large proportion of organismic biologists are interested in bats. The earlier two edited books deriving from previous bat research conferences, as well as this one, have been rigorously edited by Tom Kunz and others, with all chapters subjected to peer review. The resulting volumes, published first by Academic Press and most recently by Smithsonian, have sold widely as the definitive synthetic treatments of current scientific understanding of bats.

From foraging patterns in a single tree to social interactions across a home range, how primates use space is a key question in the field of primate behavioral ecology. Drawing on the latest advances in spatial analysis tools, this book offers practical guidance on applying geographic information systems (GIS) to central questions in primatology. An initial methodological section discusses niche modelling, home range analysis and agent-based modelling, with a focus on remote data collection. Research-based chapters demonstrate how ecologists apply this technology to a suite of topics including: calculating the intensity of use of both range and travel routes, assessing the impacts of logging, mining and hunting, and informing conservation strategies.

Current dominant thinking and practice in the private and public sectors asserts that peoples' development needs are in conflict with, or mutually exclusive to, the need to conserve the biosphere on which we depend. Consequently, we are asked to either diminish development in the name of conservation or diminish conservation in the name of development. Efforts to identify complementary objectives, or mutually acceptable trade-offs and compromises indicate, however, that this does not always have to be the case. This first volume in the State of the Apes series draws attention to the evolving context within which great ape and gibbon habitats are increasingly interfacing with extractive industries. Intended for a broad range of policy makers, industry experts, decision makers, academics, researchers and NGOs, these publications aim to influence debate, practice and policy, seeking to reconcile ape conservation and welfare, and economic and social development, through objective and rigorous analysis.
