Rory Putman addresses the question of how, in many temporate ecosystems, diverse and species-rich assemblies of ungulates manage to co-exist despite often quite extensive overlap in ecological requirements. Putman explores the potential for competition, competition tolerance and even positive facilitation amongst the members of such guilds of ungulates. As a central worked example, the author employs data resulting from over 20 years of personal research into the ecology and population dynamics of various large herbivores of the New Forest in Southern England. With these, he applies formal protocols in resource use, evidence for resource limitation and evidence for interaction between species in changing population size over the years.

In the century and a half since Charles Darwin first began formulating his theories on evolution much research has been conducted on primate cognition. In this book, Michael Tomasello and Josep Call set out to review all that is scientifically known about the cognitive skills of nonhuman primates and to assess the current state of our knowledge. The authors integrate empirical findings on the topic from the beginning of the century to the present, placing this work in theoretical perspective.

This book draws together, for the first time, the published research on the behaviour, ecology and welfare of elephants living in zoos, circuses, logging camps and other captive environments in a single comprehensive volume. It takes a multi-disciplinary approach, considering the work of zoo biologists, animal behaviour and welfare scientists, veterinarians, philosophers, zoo educators, tourism specialists, conservation biologists, lawyers and others with a professional interest in elephants. Elephants under Human Care: The Behaviour, Ecology, and Welfare of Elephants in Captivity is a valuable resource for zoo biology and animal welfare researchers. It is also useful for students and zoo professionals and managers looking for a comprehensive guide to current research on captive elephants. Although not intended as a husbandry manual, the book discusses some of the elephant welfare standards developed by the Association of Zoos and Aquariums (AZA) and the British and Irish Association of Zoos and Aquariums (BIAZA) and their relationship to current knowledge of captive elephants.

Neurobiology has undergone a revolution with many advances dependent on new techniques and approaches. This fully updated second edition reflects the recent growth areas in this subject. Its major themes are the fractionation and study of cellular and subcellular components of the nervous system, chemical neuroanatomy, and the measurement of neuronal metabolism in vivo and in vitro. Topics include the neuronal cytoskeleton; isolation of synaptosomes and their subcellular components; aspects of mitochondrial defects in neurones; and synaptic transport processes exemplified by the GABA transporter. This is an invaluable practical laboratory manual for all researchers in neurobiology; it contains step-by-step protocols and a troubleshooting guide, as well as examples of experimental data and their interpretation.

Over the past 30 years or so, research effort in behaviour and ecology has progressed from simple documentation of the habits or habitats of differ ent species to asking more searching questions about the adaptiveness of the patterns of behaviour observed; moved from documenting simply what occurs, to trying to understand why. Increasingly, studies of behav iour or ecology explore the function of particular responses or patterns of behaviour in individuals or populations - looking for the adaptiveness that has led to the adoption of such patterns either at a proximate level (what environmental circumstances have favoured the adoption of some particular strategy or response from within the animal's repertoire at that specific time) or at an evolutionary level (speculating upon what pres sures have led to the inclusion of a particular pattern of behaviour within the repertoire in the first place). Many common principles have been established - common to a wide diversity of animal groups, yet showing some precise relationship between a given aspect of behaviour or population dynamics and some particular ecological factor. In particular, tremendous advances have been made in understanding the foraging behaviour of animals - and the 'decision rules' by which they seek and select from the various resources on offer - and patterns of social organization and behaviour: the adap tiveness of different social structures, group sizes or reproductive tactics.

The remarkable story of a "talking" chimp, a leading scientist, and the profound insights they have uncovered about our species

He has been featured in cover stories in Time, Newsweek, and National Geographic, and has been the subject of a "NOVA" documentary. He is directly responsible for discoveries that have forced the scientific community to recast its thinking about the nature of the mind and the origins of language. He is Kanzi, an extraordinary bonobo chimpanzee who has overturned the idea that symbolic language is unique to our species. This is the moving story of how Kanzi learned to converse with humans and the profound lessons he has taught us about our animal cousins, and ourselves.

Experimental Hydrodynamics of Fast-Floating Aquatic Animals presents the latest research on the physiological, morphological and evolutionary factors in aquatic animal locomotion. Beginning with an overview on how to conduct experiments on swimming aquatic animals, assessing hydrodynamic forces, resistance and geometric parameters of animal bodies, the book then details how aquatic animals, such as fast-moving dolphins, can achieve high speeds without over-expelling their energy resources. It provides insights into investigations on how animals, including dolphins, sharks and swordfish can maneuver through water at high speeds, offering a natural model for improving human and technological underwater locomotion. This book is essential for researchers and practicing biologists interested in the study of aquatic animal locomotive physiology and its application to human technology. Advanced undergraduate and graduate students will also find this a helpful academic resource for further understanding animal hydrodynamics.

Since the initial description of techniques to immortalize anti body-producing B-lymphocytes by fusion with tissue culture-adapted myeloma cells, methods have been developed to produce monoclonal antibodies of defined specificity in multiple animal species. Stable hybrids can be readily produced in mice using a number of myeloma and hybridoma cell lines. To obviate the problem of identifying fusion partners in other animal species, xenohybrids have been produced using B-lymphocytes from the relevant species and mouse myeloma cells. The use of xenohybrids has minimized the problem of obtain ing stable antibody-producing hybrids in all species examined thus far. Although alternative techniques are being developed to produce monoclonal antibodies by molecular methods, hybridoma technol ogy will remain the technology of choice for producing monoclonal antibodies for a variety of applications in research and industry. The objective of Monoclonal Antibody Protocols is to provide investigators with a set of methods for producing and using mono clonal antibodies in biomedical, agricultural, and biological sciences. The book is not intended to provide methodology for all possible applications, but rather a series of methods presented in an easy-- follow format that can be used by new and established investiga tors, graduate and postgraduate fellows, and technical staff.

This book arrays recent research on the neural and behavioral lateralization of the brain relying heavily on animal modes. The authors employ the comparative method to enhance our understanding of behavior, specifically through hand use and "handedness" by drawing comparisons with studies involving primates. Topics discussed include Patterns of Lateralized Behavior in Prosimians; Behavioral Lateralization in Language-Trained Chimpanzees; Patterns of Handedness: Comparative Study of Nursery School Children and Captive Gorillas; and Rotational Behavior in Children and Adults. It is the first book of its kind devoted entirely to the question of behavioral asymmetries in all primates and thus presents a milestone as it recognizes the accumulating evidence of asymmetry and lateralized behavior in the non-human nervous system.

The woolly spider monkey, or muriqui, is one of the most endangered primate species in the world today. Because of deforestation pressures in its natural habitat-- the Atlantic coastal forests of southeastern Brazil--the muriquis are confined to less than three percent of their original range. There are now only a dozen forest fragments known to support a total muriqui population of about 500 individuals. This book traces the natural history of the muriqui from its scientific discovery in 1806 to its current, highly endangered status. The book provides a case study of this scientifically important primate species by balancing field research and ecological issues. Through Strier's accessible presentation, readers gain a broad understanding of primate behaviour and tropical conservation. The book also gives a practical account of how to set up and pursue an in-depth longitudinal study of an animal population, while describing the excitement of gaining first the muriquis' trust and then insights into their lives. The author offers the unique perspective of a highly committed anthropologist who has devoted years to the observation of this unique species, while working to train students and to protect the muriquis' remaining forest habitats. The book will interest biologists, primatologists, and zoologists, as well as anyone concerned with conservation, ecology, and animal behaviour.

This book describes the basic electrical properties of a variety of mammalian tissues in scientific terms that even a student who has had little formal training in the physics of electricity should find understandable. Familiarity with Ohm's Law is one of the few basic tenets of physics which a reader of this book is assumed to possess. Mathematical treatment is kept to a minimum and formal thermodynamic reasoning is avoided. Instead, reliance is placed upon intuitive ideas of energy with which any undergraduate student of biology who needs to study electric events should feel comfortable.

The North American opossum (Didelphis virginiana) generally is regarded as an important animal, phylogenetically. It is considered to represent a prototype marsupial and closely resembles fossil didelphids (Tyndale-Biscoe 1973). Numerous studies concerning the reproductive biology, embryology, and neurobiology of the opossum have been published. More recently, Didelphis has become popular as an animal model for gastroenterological studies because of the remarkable anatomical and physiological similarities of the esophagus as compared to that of man. Most of the studies of early development have concentrated on early cleavage stages and the formation of the three primary germ layers (Hartman 1916, 1919) and fetal membranes (Selenka 1887; McCrady 1938). The ova of Didelphis remain in the oviduct only for about 24 h before entering the uterus. A corona radiata is absent and each oocyte is surrounded only by a perivitel- line space and a zona pellucida (Talbot and DiCarlantonio 1984). During the short transit period, the egg is fertilized by a single spermatozoon (Rodger and Bedford 1982a,b).

The chimpanzee of all other living species is our closest relation, with whom we last shared a common ancestor about five million years ago. These African apes make and use a rich and varied kit of tools, and of the primates they are the only consistent and habitual tool-users and tool-makers. Chimpanzees meet the criteria of a culture as originally defined for human beings by socio-cultural anthropologists. They show sex differences in using tools to obtain and to process a variety of plant and animal foods. The technological gap between chimpanzees and human societies that live by foraging (hunter-gatherers) is surprisingly narrow at least for food-getting. Different communities of wild chimpanzees have different tool-kits and not all of this regional and local variation can be explained by the demands of the physical and biotic environments in which they live. Some differences are likely to be customs based on socially derived and symbolically encoded traditions. This book describes and analyzes the tool-use of humankind's nearest living relation. It focuses on field studies of these apes across Africa, comparing their customs to see if they can justifiably be termed cultural. It makes direct comparisons with the material culture of human foraging peoples. The book evaluates the chimpanzee as an evolutionary model, showing that chimpanzee behavior helps us to infer the origins of technology in human prehistory.

Throughout North America, non-native wild pigs have become an ecologically and economically destructive invasive species. Though they are regarded as a popular game species by some, provide economic benefits to others, and are even engrained into societal heritage in some areas, wild pigs are responsible for an extraordinary amount of damage in both natural and anthropogenic systems throughout North America. As the density and range of wild pig habitat have substantially increased over the last several decades, the magnitude and diversity of their negative impacts are not yet fully realized or quantified. With various conflicts continually emerging, wild pig management is difficult and expensive to achieve. As a result, wild pigs represent one of the greatest wildlife management challenges North America faces in the 21st century. Invasive Wild Pigs in North America: Ecology, Impacts, and Management addresses all aspects of wild pig biology, ecology, damage, and management in a single comprehensive volume. It assimilates and organizes information on the most destructive introduced vertebrate species in the United States, establishing a foundation from which managers, researchers, policy makers, and other stakeholders can build upon into the future. The book provides comprehensive coverage of wild pig biology and ecology, techniques for management and research, and regional chapters. It is an asset to readers interested in wild pigs, the resources they impact, and how to mitigate those impacts, and establishes a vision of the future of wild pigs in North America. Features: Compiles valuable knowledge for a broad audience including wild pig managers, researchers, adversaries, and enthusiasts from across North America Addresses taxonomy, morphology, genetics, physiology, spatial ecology, population dynamics, diseases and parasites, and the naturalized niche of wild pigs Includes chapters on damage to resources, management, research methods, human dimensions and education, and policy and legislation Contains full color images and case studies of interesting and informative situations being created by wild pigs throughout North America Includes a chapter on wild pigs at the wildland-urban interface, a more recent and especially challenging issue

Organized under broad ecological headings, this book provides a representative selection of present knowledge of mammal ecology with examples selected from a wide range of species and from all parts of the world.

The development of the breast-shoulder apparatus in the Marsupialia was inves tigated and compared with the conditions in Monotremata and Placentalia. The results were achieved by the investigation of material comprising altogether 109 histological serial sections of intrauterine embryos, neonates, and pouch young from 11 marsupial species. Additionally, 54 skeletons of subadult and adult marsupials from 25 species were included for comparison. The embryonic states show a strong similarity to the developmental stage of the breast-shoulder apparatus in the monotremes. In contrast, the adult breast-shoulder apparatus generally corresponds to that in placentals. The following elements can be observed in the marsupial breast-shoulder apparatus during embryogenesis: scapula, metacoracoid, procoracoid, first rib, paired sternal elements, unpaired sternal element, and clavicle. All the elements mentioned together form a compact, continuous arch in both the intrauterine embryos and the neonates. In the pouch young, this arch is reduced rather soon after birth, so that a compact connection between the left and the right half of the body no longer exists. All that remains is a loose connection via the clavicle. The metacoracoid becomes the processus coracoideus scapulae. The procoracoid becomes the praeclavium. The unpaired sternal element fuses with the paired sternal element, generating the uniform manubrium sterni. The first rib takes its usual position in the thorax. In the pouch young, the breast shoulder apparatus as a whole already shows all the typical characteristics that can be determined in adults.

Mammalian sociobiology is a rapidly advancing field which has made enormous strides in the last ten years. The last major monograph on the subject (Ewer, 1968) was published sixteen years ago, and there is a need for this information to be examined in terms of modern sociobiological theory. My approach throughout is evolutionary and is therefore directed strongly towards research which throws light on the ways in which mammals behave in their natural environments. I have tried to cover as wide a range of mammalian species as possible, although, in some cases, the only data available were obtained from captive individuals. The coverage of this book is not a reflection of the volume of literature published on different species, as I have tried to avoid undue emphasis on the social behaviour of primates and laboratory rodents. I have made scrupulous efforts throughout to avoid an anthropomorphic approach to mammalian behaviour. Terms such as 'strategy', 'evaluation' or 'choice' do not therefore imply conscious planning, but are used neutrally in the way in which they would be applied to a chess-playing computer. In the case of mammals, the programmer was natural selection. While I am fully aware that human beings are mammals, any detailed consideration of human social behaviour lies outside the scope of this book. However, the book may provide a complementary text to those interested in that subject.

The first ethnographic exploration of the contentious debate over whether nonhuman primates are capable of culture In the 1950s, Japanese zoologists took note when a number of macaques invented and passed on new food-washing behaviors within their troop. The discovery opened the door to a startling question: Could animals other than humans share social knowledge-and thus possess culture? The subsequent debate has rocked the scientific world, pitting cultural anthropologists against evolutionary anthropologists, field biologists against experimental psychologists, and scholars from Asia against their colleagues in Europe and North America. In Chimpanzee Culture Wars, the first ethnographic account of the battle, anthropologist Nicolas Langlitz presents first-hand observations gleaned from months spent among primatologists on different sides of the controversy. Langlitz travels across continents, from field stations in the Ivory Coast and Guinea to laboratories in Germany and Japan. As he compares the methods and arguments of the different researchers he meets, he also considers the plight of cultural primatologists as they seek to document chimpanzee cultural diversity during the Anthropocene, an era in which human culture is remaking the planet. How should we understand the chimpanzee culture wars in light of human-caused mass extinctions? Capturing the historical, anthropological, and philosophical nuances of the debate, Chimpanzee Culture Wars takes us on an exhilarating journey into high-tech laboratories and breathtaking wilderness, all in pursuit of an answer to the question of the human-animal divide.

Since 2013, an organization called the Nonhuman Rights Project has brought before the New York State courts an unusual request-asking for habeas corpus hearings to determine whether Kiko and Tommy, two captive chimpanzees, should be considered legal persons with the fundamental right to bodily liberty. While the courts have agreed that chimpanzees share emotional, behavioural, and cognitive similarities with humans, they have denied that chimpanzees are persons on superficial and sometimes conflicting grounds. Consequently, Kiko and Tommy remain confined as legal "things" with no rights. The major moral and legal question remains unanswered: are chimpanzees mere "things", as the law currently sees them, or can they be "persons" possessing fundamental rights? In Chimpanzee Rights: The Philosophers' Brief, a group of renowned philosophers considers these questions. Carefully and clearly, they examine the four lines of reasoning the courts have used to deny chimpanzee personhood: species, contract, community, and capacities. None of these, they argue, merits disqualifying chimpanzees from personhood. The authors conclude that when judges face the choice between seeing Kiko and Tommy as things and seeing them as persons-the only options under current law-they should conclude that Kiko and Tommy are persons who should therefore be protected from unlawful confinement "in keeping with the best philosophical standards of rational judgment and ethical standards of justice." Chimpanzee Rights: The Philosophers' Brief-an extended version of the amicus brief submitted to the New York Court of Appeals in Kiko's and Tommy's cases-goes to the heart of fundamental issues concerning animal rights, personhood, and the question of human and nonhuman nature. It is essential reading for anyone interested in these issues.

Whales and dolphins are icons for the conservation movement. They are the most conspicuous ambassadors for entire marine ecosystems and possibly even for the biosphere as a whole. Concurrent with our realisation of impending threats to their environment is a growing scientific understanding of the social and cognitive complexity of many of these species. This book brings together experts in the relevant diverse fields of cetacean research, to provide authoritative descriptions of our current knowledge of the complex behaviour and social organization of whales and dolphins. The authors consider this new information in the context of how different human cultures from around the world view cetaceans and their protection, including attitudes to whaling. They show how new information on issues such as cetacean intelligence, culture and the ability to suffer, warrants a significant shift in global perceptions of this group of animals and how these changes might be facilitated to improve conservation and welfare approaches.

Despite its remote and seemingly rigorous environment, the Antarctic is the world's most important habitat for seals, currently supporting more seals than all other parts of the world combined. As various national Antarctic programmes were established to study these animals, the need to standardize techniques became apparent. This book, arising from work by the Scientific Committee on Antarctic Research (Group of Specialists on Seals), gives a detailed account of well-tried and, where possible, agreed methodologies, techniques, procedures and rationale for the collection and initial analysis of data on the biology and population ecology of Antarctic seals. This volume will not only help facilitate comparisons between different regions of Antarctica, but will also provide a guide for those studying seals in other parts of the world and those carrying out research on other large mammal species.
