Primates communicate with each other using a wide range of signals: olfactory signals to mark territories, screams to recruit help while fighting, gestures to request food and facial expressions to initiate play. Primate Communication brings together research on all forms of interchange and discusses what we know about primate communication via vocal, gestural, facial, olfactory and integrated multimodal signals in relation to a number of central topics. It explores the morphological, neural and cognitive foundations of primate communication through discussion of cutting-edge research. By considering signals from multiple modalities and taking a unified multimodal approach, the authors offer a uniquely holistic overview of primate communication, discussing what we know, what we don't know and what we may currently misunderstand about communication across these different forms. It is essential reading for researchers interested in primate behaviour, communication and cognition, as well as students of primatology, psychology, anthropology and cognitive sciences.

Immunity studies in sharks over the past three decades have produced some remarkable discoveries. If one message rings true, it is that alternative animal model systems, such as sharks and their relatives, have contributed very substantially to a better understanding of the development evolution of our own immune system. Immunobiology of the Shark describes the cellular, genetic, and molecular specifics of immune systems in sharks. Diverse approaches were employed to study the immunobiology of the shark from basic microscopic observations to detailed genome annotation. The book also raises a series of fascinating questions, which can be addressed experimentally using today's technology. This book will be a valuable resource for mainstream immunologists, comparative immunologists, geneticists, ecologists, evolutionary biologists, and investigators engaged in shark research. The book also aims to illustrate the magnificence of these animals as model systems and underscores the importance of their study to further understand their complex, and often enigmatic, biology.

Arthur Shipley (1861-1927) was a British zoologist who held the position of Vice-Chancellor at the University of Cambridge from 1917 to 1919. First published in 1925, as the second edition of a 1923 original, this book was written by Shipley to provide students of elementary biology with an understanding of the unity and interconnectedness of life. The text attempts to bring out the fact that plants and animals are at one in being alive and makes clear the intimate association of both with their environment, whether it be the air, the soil or the sea. Numerous illustrative figures are included. This book will be of value to anyone with an interest in the history of education and Shipley's writings.

Thomas Bewick (1753-1828) is synonymous with finely crafted wood engravings of the natural world, and his instantly recognisable style influenced book illustration well into the nineteenth century. During his childhood in the Tyne valley, his two obsessions were art and nature. At fourteen, he was apprenticed to the engraver and businessman Ralph Beilby (1743-1817) with whom he later published A General History of Quadrupeds (also reissued in this series). The present work, with its text compiled from various sources, was the first practical field guide for the amateur ornithologist, inspiring also artists and writers. Each of the two volumes contains hundreds of illustrations of breathtaking beauty and precision: one for each species, neatly capturing its character in exquisite detail, interspersed with charming vignettes of country life. Volume 2, first published in 1804, covers water birds, including sandpipers, terns, grebes and guillemots.

Southern India is home to the greatest concentration of elephants in Asia. However, populations are fast diminishing and the Asian elephant is faced with extinction. In order to save this endangered creature we must increase our knowledge of this crucial population.

This is the broadest treatment of the subject yet,written by one of the leading workers in the field, Raman Sukumar, the book promises to bring the understanding of elephants to a new level, making it of interest not only to biologists but also a broader audience including field ecologists, wildlife administrators, historians, conservationists and all those interested in elephants and their future.

The Golden Eagle is generally thought to be a well-known and well-documented species. However, much of the available literature is not necessarily in a form that can readily be used in the field. In fact, although much existing information about Golden Eagles has little supporting evidence it is still largely accepted without question. This book addresses this important issue and in doing so the author queries numerous long-held beliefs about Golden Eagles. He suggests that failure to recognize the limitations of the available evidence is not only detrimental to understanding eagle ecology but that it can undermine conservation efforts. The Fieldworker's Guide questions the reliability of existing knowledge and promotes a better understanding of the species through improved fieldwork. With 37 years of active, year-round investigative fieldwork experience of the Golden Eagle, the author has vast knowledge enabling him to shed light on these matters. He has a history of undertaking novel research on post-fledging studies, territories and the impact of changes in land use.In this context he discusses how best to undertake fieldwork to produce objective results, avoiding the influence of expectations and recognizing the many pitfalls into which an unwary observer might stumble. The book objectively reviews all aspects of Golden Eagle ecology, taking examples from many different locations and from site-specific studies in Scotland to compare and contrast the reliability and relevance of the evidence, highlighting the differences between casual and intensive fieldwork. It reviews all the elements of Golden Eagle ecology, from the species status, through the activities and roles of eagles of different gender, age and status, via territories, food and breeding, to habitat preferences, usage and even the influence of weather and observer activity on behavior and observations. It also gives due consideration to the failed and non-breeding elements of the population, topics that are widely ignored despite such eagles forming the bulk of the population for most of the year.To provide a better understanding of what fieldworkers and birdwatchers are likely to encounter, the author reviews the month-by-month activity of all classes of Golden Eagle and the influences that affect how their ecology is understood.

'Full of wonder and forensic intelligence' Isabella Tree, author of Wilding A moving account of Madagascar told by a researcher who has spent over fifty years investigating the mysteries of this remarkable island. Madagascar is a place of change. A biodiversity hotspot and the fourth largest island on the planet, it has been home to a spectacular parade of animals, from giant flightless birds and giant tortoises on the ground, to agile lemurs leaping through the treetops. Some species live on; many have vanished in the distant or recent past. Over vast stretches of time, Madagascar's forests have expanded and contracted in response to shifting climates, and the hand of people is clear in changes during the last thousand years or so. Today, Madagascar is a microcosm of global trends. What happens there in the decades ahead can, perhaps, suggest ways to help turn the tide on the environmental crisis now sweeping the world. The Sloth Lemur's Song is a far-reaching account of Madagascar's past and present, led by an expert guide who has immersed herself in research and conservation activities with village communities on the island for nearly fifty years. Alison Richard accompanies the reader on a journey through space and time-from Madagascar's ancient origins as a landlocked region of Gondwana and its emergence as an island to the modern-day developments that make the survival of its array of plants and animals increasingly uncertain. Weaving together scientific evidence with Richard's own experiences and exploring the power of stories to shape our understanding of events, this book captures the magic as well as the tensions that swirl around this island nation.

Conservation Physiology for the Anthropocene: A Systems Approach, Volume 39A in the Fish Physiology series, is a comprehensive synthesis on the physiology of fish in the Anthropocene. This volume closes the knowledge gap by considering the many ways in which different physiological systems (e.g., sensory physiology, endocrine, cardio-respiratory, bioenergetics, water and ionic balance and homeostasis, locomotion/biomechanics, gene function) and physiological diversity are relevant to management and conservation. As the world is changing, with a dire need to identify solutions to the many environmental problems facing wild fish populations, this book comprehensively covers conservation physiology and its future techniques. Conservation physiology reveals the many ways in which environmental change and human activities can negatively influence wild fish populations. These tactics inform new management and conservation activities and help create the necessary conditions for fish to thrive.

Recent genetic data showing that Neanderthals interbred with modern humans have made it clear that deeper insight into the behavioral differences between these populations will be critical to understanding the rapid spread of modern humans and the demise of the Neanderthals. This volume, which brings together scholars who have worked with faunal assemblages from Europe, the Near East, and Africa, makes an important contribution to our broader understanding of Neanderthal extinction and modern human origins through its focus on variability in human hunting behavior between 70-25,000 years ago-a critical period in the later evolution of our species.

The neotropical primate family Pitheciidae consists of four genera Cacajao (uacaris), Callicebus (titis), Chiropotes (bearded sakis) and Pithecia (sakis), whose 40+ species display a range of sizes, social organisations, ecologies and habitats. Few are well known and the future survival of many is threatened, yet pitheciines have been little studied. This book is the first to review the biology of this fascinating and diverse group in full. It includes fossil history, reviews of the biology of each genus and, among others, specific treatments of vocalisations and foraging ecology. These studies are integrated into considerations of current status and future conservation requirements on a country-by-country basis for each species. A state-of-the-art summary of current knowledge, Evolutionary Biology and Conservation of Titis, Sakis and Uacaris is a collective effort from all the major researchers currently working on these remarkable animals.

The Multilingual Illustrated Dictionary of Aquatic Animals and Plants provides a unique reference to the names of 1532 species of fish, crustaceans, molluscs, seaweeds and other fishery products that are landed worldwide. The names of these species can vary significantly between neighbouring regions of a country, from the size of the fish, from the stage of its life cycle, from the season of the year, and from its degree of treatment after capture. Co--published by the European Commission and Fishing News Books, the Multilingual Illustrated Dictionary of Aquatic Animals and Plants seeks to address this problem and to eliminate much of the existing confusion. New to the Second Edition of this acclaimed Dictionary is the addition of Finnish and Swedish to each existing entry. The Dictionary has been expanded to include new species and illustrations. For each entry, the following information is given: Reference number (the number given to the species within the index); Scientific (Latin) name; Family name; English name; Dutch name; French name; Danish name; German name; Greek name; Italian name; Portuguese name; Spanish name; Finnish name; Swedish name. Comprehensively illustrated, the New Second Edition of the multilingual Illustrated Dictionary of Aquatic Animals and Plants is an essential reference for all involved in the commercial fishing industries both within and beyond the boundaries of the European Union

'Birds have been to me the solace, the recreation, the passion of a lifetime.' So wrote Reginald Bosworth Smith (1839 1908), former Classics master at Harrow School. As a young man, he published his first book on birds while teaching at Oxford, and he continued to combine his lifelong love of birds with classical and literary teaching and research. He retired to a country house in Dorset and in 1905 published this book, based on a series of articles written in his retirement. Recording his own observations, some of many years before, and peppered with scholarly references to birds in literature, the essays cover individual birds such as the owl, the raven and the magpie, as well as bird-watching in Dorset and beyond. Imparting a love and respect for wildlife that remains inspiring, this book will be of great interest to the bird-lover and scholar of today.

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 successful conservation of bird species relies upon our understanding of their habitat use and requirements. In the coming decades the importance of such knowledge will only grow as climate change, the development of new energy sources and the needs of a growing human population intensify the, already significant, pressure on the habitats that birds depend on. Drawing on valuable recent advances in our understanding of bird-habitat relationships, this book provides the first major review of avian habitat selection in over twenty years. It offers a synthesis of concepts, patterns and issues that will interest students, researchers and conservation practitioners. Spatial scales ranging from landscape to habitat patch are covered, and examples of responses to habitat change are examined. European landscapes are the main focus, but the book has far wider significance to similar habitats worldwide, with examples and relevant material also drawn from North America and Australia.

Speech has long been thought of as a uniquely defining characteristic of humans. Yet song birds, like humans, communicate using learned signals (song, speech) that are acquired from their parents by a process of vocal imitation. Both song and speech begin as amorphous vocalizations (subsong, babble) that are gradually transformed into an individualized version of the parents' speech, including dialects. With contributions from both the founding forefathers and younger researchers of this field, this book provides a comprehensive summary of birdsong neurobiology, and identifies the common brain mechanisms underlying this achievement in both birds and humans. Written primarily for advanced graduates and researchers, there is an introductory overview covering song learning, the parallels between language and birdsong and the relationship between the brains of birds and mammals; subsequent sections deal with producing, processing, learning and recognizing song, as well as with hormonal and genomic mechanisms.

Widespread in North American forest regions including the Rocky Mountains, the Boreal Owl (Aegolius funereus) was once the most numerous predatory bird in Eurasian boreal forests. Synthesising the results of unique long-term studies of Boreal Owls, this book explores hunting modes, habitats and foods, prey interactions, mating and parental care, reproduction, dispersal, survival and mortality, population regulation and conservation in boreal forests. Providing a detailed introduction to the species, the authors study the complex interactions of Boreal Owls with their prey species. They examine the inter-sexual tug-of-war over parental care, and the behavioural and demographic adaptations to environmental conditions that predictably and markedly fluctuate both seasonally and multi-annually. They also question whether Boreal Owls are able to time their reproductive effort to maximise lifetime reproductive success. Discussing the effect of modern forestry practices on owl populations, the book also examines how Boreal Owls could be managed to sustain viable populations.

How do chimpanzees say, 'I want to have sex with you?' By clipping a leaf or knocking on a tree trunk? How do they eat live aggressive ants? By using a short stick with one hand or long stick with both? Ivorian and Tanzanian chimpanzees answer these questions differently, as would humans from France and China if asked how they eat rice. Christophe Boesch takes readers into the lives of chimpanzees from different African regions, highlighting the debate about culture. His ethnography reveals how simple techniques have evolved into complex ones, how teaching styles differ, how material culture widens access to new food sources and how youngsters learn culture. This journey reveals many parallels between humans and chimpanzees and points to striking differences. Written in a vivid and accessible style, Wild Cultures places the reader in social and ecological contexts that shed light on our twin cultures.

These charismatic mammals, which include dogs, cats, hyenas, weasels, mongooses, seals, sea lions and bears, have always held special importance to humans throughout history and continue to do so today. In recent decades, the emergence of new technologies has completely transformed our knowledge of how carnivorans interact with their environments and consequently reshaped our view of carnivoran ecology. This unique synthesis uses examples from a diverse and expanding carnivoran literature, drawing from all carnivoran families and spanning the world's oceans and continents, to produce a clearly written and richly illustrated book that reviews our current state of knowledge of carnivoran ecology. It addresses all levels of biological organization and function, from genes to enzymes, organisms, populations, and ecosystems. Special attention is given to how carnivoran species interact with their prey, each other, and humans. There is an emphasis on community interactions and their importance in carnivoran evolution, showing how evolutionary constraints (morphological, physiological, and behavioral) structure communities today. The book's approach is strongly comparative, contrasting herbivores with carnivores, predators with scavengers, and cats with dogs. Carnivorans play important roles in many high-profile conservation cases, either as species of concern or agents of endangerment, and their importance is demonstrated in both contexts. Carnivoran Ecology is an accessible advanced textbook aimed principally at senior undergraduate and graduate students taking courses in carnivore ecology, as well as a broad audience of professional academics (especially carnivore and mammalian biologists), researchers, and practitioners working in both governmental and non-governmental organizations. A significant secondary market will exist amongst the large amateur naturalist community including those wishing to explore the ecological and evolutionary links between domestic carnivorans (dogs, cats, ferrets etc.) and their wild counterparts.
