Despite many encouraging developments in the field of animal-free technologies, well-defined animal models are still needed to study fundamental properties of human diseases and to develop new prophylactic and therapeutic treatments against human diseases. Non-human primates (NHP) make up only a small, but important, part of the total number of animals used in biomedical and preclinical research. Due to their close phylogenetic relationship and the shared susceptibility to many human diseases, NHP can provide important research models to study these diseases and, as such, play a critical role in the advancement of various areas in the medical field. Studies in NHP have contributed to our understanding of various diseases and fundamental biological phenomena and they continue to be important in the development of new therapies, treatments, drugs and vaccines. Moreover, NHP models also contribute to our general knowledge of the processes that underlie non-disease and disease conditions. Important areas where NHP can provide important information include (emerging) infectious diseases, organ transplantation, neurological and aging-related disorders. Although not covered in this book due to time constraints, the need for, and benefits of, NHP models has been demonstrated most recently in the SARS-CoV-2 pandemic. The present book is the second of two volumes and covers important disease areas where NHP are used as model species. This volume includes different chapters on NHP models in infectious diseases, aging, neurodegenerative disorders, organ transplantation and cancer.

The New World primates have radiated widely in tropical America, evolving a variety of adaptations to cope with different ways of life. This comparative survey examines many species. Some are highly specialized in unique ways; others have paralleled the lemurs of Madagascar or the monkeys and apes of Africa and Asia. The author's emphasis is on natural history, behavior, and ecology. Topics include geographical distributions, habitat preferences, territorial arrangements, activity rhythms, feeding techniques, defense mechanisms, and competition and cooperation among individuals of the same species. Much of the material is new, based on recent research in the field. Social reactions and organizations, and communication systems, are discussed in order to consider their implications for the evolution of primates in general and the development of languages and intelligence.

Beavers are widely recognised as a keystone species which play a pivotal role in riparian ecology. Their tree felling and dam building behaviours coupled with a suite of other activities create a wealth of living opportunities that are exploited by a range of other species. Numerous scientific studies demonstrate that beaver-generated living environments that are much richer in terms of both biodiversity and biomass than wetland environments from which they are absent. Emerging contemporary studies indicate clearly that the landscapes they create can afford sustainable, cost-effective remedies for water retention, flood alleviation, silt and chemical capture. Beaver activities, especially in highly modified environments, may be challenging to certain land use activities and landowners. Many trialled and tested methods to mitigate against these impacts, including a wide range of non-lethal management techniques, are regularly implemented across Europe and North America. Many of these techniques will be new to people, especially in areas where beavers are newly re-establishing. This handbook serves to discuss both the benefits and challenges in living with this species, and collates the wide range of techniques that can be implemented to mitigate any negative impacts. The authors of this handbook are all beaver experts and together they have a broad range of scientific knowledge and practical experience regarding the ecology, captive husbandry, veterinary science, pathology, reintroduction and management of beavers in both continental Europe and Britain.

This book presents an alternative to conventional ideas about the evolution of the human intellect. Instead of placing top priority on the role of tools, the pressure for their skillful use, and the related importance of interpersonal communication as a means for enhanced cooperation, this volume explores quite a different idea-- that the driving force in the evolution of human intellect was social expertise--a force which enabled the manipulation of others within the social group, who themselves are seen as posing the most challenging problems faced by primitive humans. The need to outwit one's clever colleagues then produces an evolutionary spiraling of "Machiavellian intelligence." The book forms a complete and self-contained text on this fast-growing topic. It includes the origins of the basic premise and a wealth of exciting developments, described by an international team of authors from the fields of anthropology, psychology, and zoology. An evaluation of more traditional approaches is also undertaken, with a view to discovering to what extent Machiavellian intelligence represents a complementary concept or one that is truly an alternative. Readers and students will find this fascinating volume carries them to the frontiers of scientific work on the origin of human intellect.

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.

Beginning in 1984, Eric Dinerstein led a team directly responsible for the recovery of the greater one-horned rhinoceros in the Royal Chitwan National Park in Nepal, where the population had once declined to as few as 100 rhinos. The Return of the Unicorns is an account of what it takes to save endangered large mammals. In its pages, Dinerstein outlines the multifaceted recovery program-structured around targeted fieldwork and scientific research, effective protective measures, habitat planning and management, public-awareness campaigns, economic incentives to promote local guardianship, and bold, uncompromising leadership-that brought these extraordinary animals back from the brink of extinction. In an age when scientists must also become politicians, educators, fund-raisers, and activists to safeguard the subjects that they study, Dinerstein's inspiring story offers a successful model for large-mammal conservation that can be applied throughout Asia and across the globe.

Marsupials differ from most other mammals in their method of reproduction, in that they have chosen, in an evolutionary sense, to develop lactation rather than placentation for the nurture of their young. The neonate is therefore born with a mixture of advanced and embryonic characters, and yet is readily accessible within the pouch, providing a unique system for the study of the ontogeny of various physiological and endocrinological parameters. Marsupials are therefore ideal animals for research into mammalian reproductive physiology. The results of this exciting new research are summarized in this book by two of the foremost workers in the field. Individual chapters analyse the genetic and hormonal control of sexual differentiation, male and female reproductive structures and their functions, the role of the corpus luteum in the oestrous cycle and pregnancy, the hormonal control of embryonic diapause and the role of the marsupial placenta in the development of the embryo. This book is more than just a straightforward review of marsupial reproduction for its detailed analyses and broad comparative coverage will attract mammalogists and reproductive physiologists with a wide range of research interests.

Grizzly bears can climb trees; black bears can be brown - or even white, and some coastal bears will not hibernate at all. These facts, and the vibrant photographs of bears, underscore The Bear Man's true message, which is: learn how to behave around bears; know proper 'bear manners' and you - and the bear - will survive an encounter. Armed with just bear spray and the knowledge he has acquired in nearly forty years of studying bears in their natural habitat, Keith Scott hikes the wilds of Canada and Alaska, looking for bears, living where they live. His adventures and experience have made him a specialist on bear habitats and behaviour, and his commitment is to teach people about these misunderstood and magnificent animals.

The interactions between apex predators and their prey are some of the most awesome and meaningful in nature - displays of strength, endurance, and a deep coevolutionary history. And there is perhaps no apex predator more impressive and important in its hunting - or more infamous, more misjudged - than the wolf. Because of wolves' habitat, speed, and general success at evading humans, researchers have faced great obstacles in studying their natural hunting behaviors. The first book to focus explicitly on wolf hunting of wild prey, Wolves on the Hunt seeks to remedy these gaps in our knowledge and understanding. Combining behavioral data, thousands of hours of original field observations, research in the literature, a wealth of illustrations, and - in the e-book edition and online - video segments, the authors create a compelling and complex picture of these hunters. The wolf is indeed an adept killer, able to take down prey much larger than itself. While adapted to hunt primarily hoofed animals, a wolf - or especially a pack of wolves - can kill individuals of just about any species. But even as wolves help drive the underlying rhythms of the ecosystems they inhabit, their evolutionary prowess comes at a cost: wolves spend one third of their time hunting - the most time-consuming of all wolf activities - and success at the hunt only comes through traveling long distances, persisting in the face of regular failure, detecting and taking advantage of deficiencies in the physical condition of individual prey, and through ceaseless trial and error, all while risking injury or death. By describing and analyzing the behaviors wolves use to hunt and kill various wild prey - including deer, moose, caribou, elk, Dall sheep, mountain goats, bison, muskoxen, arctic hares, beavers, and others - Wolves on the Hunt provides a revelatory portrait of one of nature's greatest hunters.

The ecological literature on marsupials is dominated by descriptive natural history, and there has hitherto been little attempt at either synthesis or evolutionary interpretation. This book attempts to provide such a synthesis, by drawing on both the descriptive data base and predictions from the burgeoning literature on behavioural and evolutionary ecology. It documents the excellent potential the study of marsupials provides for resolution of theoretical questions of general importance in biology. It does this in three ways. First, by describing the impressive diversity of marsupial life history strategies and trophic roles. Second, by careful comparison with the eutherians, the scope of the marsupial radiation is used to analyse the role of developmental constraints and adaptive radiation in determining the diversification of higher taxa. Lastly, it is suggested that the accessibility of marsupial young during their obligatory pouch life facilitates measurement, manipulation and assessment of kinship not possible in other mammalian groups. Further special topics include marsupial/plant mutualism, marsupial competition and the empirical uses of mammals with simple life histories.

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. Originally published in 1997.

Our closest living relatives, the chimpanzees, are familiar enough--bright and ornery and promiscuous. But they also kill and eat their kin, in this case the red colobus monkey, which may say something about primate--even hominid--evolution. This book, the first long-term field study of a predator-prey relationship involving two wild primates, documents a six-year investigation into how the risk of predation molds primate society. Taking us to Gombe National Park in Tanzania, a place made famous by Jane Goodall's studies, the book offers a close look at how predation by wild chimpanzees--observable in the park as nowhere else--has influenced the behavior, ecology, and demography of a population of red colobus monkeys.

As he explores the effects of chimpanzees' hunting, Craig Stanford also asks why these creatures prey on the red colobus. Because chimpanzees are often used as models of how early humans may have lived, Stanford's findings offer insight into the possible role of early hominids as predators, a little understood aspect of human evolution.

The first book-length study in a newly emerging genre of primate field study, "Chimpanzee and Red Colobus "expands our understanding of not just these two primate societies, but also the evolutionary ecology of predators and prey in general.

In 1838 Charles Darwin jotted in a notebook, "He who understands baboon would do more towards metaphysics than Locke." "Baboon Metaphysics "is Dorothy L. Cheney and Robert M. Seyfarth's fascinating response to Darwin's challenge.
Cheney and Seyfarth set up camp in Botswana's Okavango Delta, where they could intimately observe baboons and their social world. Baboons live in groups of up to 150, including a handful of males and eight or nine matrilineal families of females. Such numbers force baboons to form a complicated mix of short-term bonds for mating and longer-term friendships based on careful calculations of status and individual need.
But "Baboon Metaphysics" is concerned with much more than just baboons' social organization--Cheney and Seyfarth aim to fully comprehend the intelligence that underlies it. Using innovative field experiments, the authors learn that for baboons, just as for humans, family and friends hold the key to mitigating the ill effects of grief, stress, and anxiety.
Written with a scientist's precision and a nature-lover's eye, "Baboon Metaphysics" gives us an unprecedented and compelling glimpse into the mind of another species.
"The vivid narrative is like a bush detective story."--Steven Poole, "Guardian"
""Baboon Metaphysics "is a distillation of a big chunk of academic lives. . . . It is exactly what such a book should be--full of imaginative experiments, meticulous scholarship, limpid literary style, and above all, truly important questions."--Alison Jolly, "Science"
"Cheney and Seyfarth found that for a baboon to get on in life involves a complicated blend of short-term relationships, friendships, and careful status calculations. . . . Needless to say, the ensuing political machinations and convenient romantic dalliances in the quest to become "numero uno" rival the bard himself."--"Science News" "Cheney and Seyfarth's enthusiasm is obvious, and their knowledge is vast and expressed with great clarity. All this makes "Baboon Metaphysics" a captivating read. It will get you thinking--and maybe spur you to travel to Africa to see it all for yourself."--Asif A. Ghazanfar, "Nature"
"Through ingenious playback experiments . . . Cheney and Seyfarth have worked out many aspects of what baboons used their minds for, along with their limitations. Reading a baboon's mind affords an excellent grasp of the dynamics of baboon society. But more than that, it bears on the evolution of the human mind and the nature of human existence."--Nicholas Wade, "New York"" Times"

The badgers of Wytham Woods (Oxford, UK) have been studied continuously and intensively by David Macdonald for almost 50 years (25 of them with his former student and co-author Chris Newman), generating a wealth of data pertaining to every facet of their ecology and evolution. Through a mix of accessible, highly readable prose and cutting-edge science, the authors weave a riveting scientific story of the lives of these intriguing creatures, highlighting the insights offered to science more broadly through badgers as a model system. They provide a paradigm - from population down to molecule - for a deeper understanding of mammalian behaviour, ecology, epidemiology, evolutionary biology, and conservation. The real value of this long-term study is particularly apparent with current and globally relevant challenges such as climate change, disease epidemics, and senescence. This unique dataset enables us to examine these issues in a context that only a half-century experiment can reveal. The Badgers of Wytham Woods will appeal to a broad audience of professional academics (especially carnivore and mammalian biologists), researchers and students at all levels, governmental and non-governmental wildlife bodies, and to the natural historian fascinated by wild animals and the remarkable processes of nature they exemplify.

What is animal welfare? Why has it proved so difficult to find a definition that everyone can agree on? This concise and accessible guide is for anyone who is interested in animals and who has wondered how we can assess their welfare scientifically. It defines animal welfare as 'health and animals having what they want', a definition that can be easily understood by scientists and non-scientists alike, expresses in simple words what underlies many existing definitions, and shows what evidence we need to collect to improve animal welfare in practice. Above all, it puts the animal's own point of view at the heart of an assessment of its welfare. But, can we really understand what animals want? A consistent theme running through the book is that not only is it possible to establish what animals want, but that this information is vital in helping us to make sense of the long and often confusing list of welfare measures that are now in use such as 'stress' and 'feel good hormones', expressive sounds and gestures, natural behaviour, cognitive bias, and stereotypies. Defining welfare as 'health and what animals want' allows us to distinguish between measures that are simply what an animal does when it is alert, aroused, or active and those measures that genuinely allow us to distinguish between situations the animals themselves see as positive or negative. Sentience (conscious feelings of pleasure, pain, and suffering) is for many people the essence of what is meant by welfare, but studying consciousness is notoriously difficult, particularly in non-human species. These difficulties are discussed in the context of our current - and as yet incomplete - knowledge of human and animal consciousness. Finally, the book highlights some key ideas in the relationship between animal welfare science and animal ethics and shows how closely the well-being of humans is linked to that of other animals. The Science of Animal Welfare is an ideal companion for undergraduate and graduate students taking courses in animal behaviour and welfare, as well as for professional researchers, practitioners and animal welfare consultants. At the same time, it is easily understandable to non-scientists and anyone without prior knowledge but with an interest in animals and the rapidly evolving science of animal welfare.

This book brings together scientific evidence and experience relevant to the practical conservation of bats. The authors worked with an international group of bat experts and conservationists to develop a global list of interventions that could benefit bats. For each intervention, the book summarises studies captured by the Conservation Evidence project, where that intervention has been tested and its effects on bats quantified. The result is a thorough guide to what is known, or not known, about the effectiveness of bat conservation actions throughout the world. Bat Conservation is the fifth in a series of Synopses that will cover different species groups and habitats, gradually building into a comprehensive summary of evidence on the effects of conservation interventions for all biodiversity throughout the world. By making evidence accessible in this way, we hope to enable a change in the practice of conservation, so it can become more evidence-based. We also aim to highlight where there are gaps in knowledge. Evidence from all around the world is included. If there appears to be a bias towards evidence from northern European or North American temperate environments, this reflects a current bias in the published research that is available to us. Conservation interventions are grouped primarily according to the relevant direct threats, as defined in the International Union for the Conservation of Nature (IUCN)'s Unified Classification of Direct Threats (www.iucnredlist.org/technical-documents/classification-schemes).

Robin Dunbar uses economic models to explore the social behavior of the gelada baboon (Theropithecus gelada), a unique species, whose social system is one of the most complex among the primates. His work illustrates the value of an approach that views social behavior as being ultimately concerned with reproduction and with the maximizing of an individual's contribution to its species' gene pool.

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.

We have long attributed man's violent, aggressive, competitive nature to his animal ancestry. But what if we are just as given to cooperation, empathy and morality by virtue of our genes? From a scientist and writer whom E. O. Wilson has called 'the world authority on primate social behavior' comes a lively look at the most provocative aspects of human nature - power, sex, violence, kindness, and morality - through our two closest cousins in the ape family. For nearly twenty years, Frans de Waal has worked with both the famously aggressive chimpanzee and the lesser-known egalitarian, erotic, matriarchal bonobo, two species whose DNA is nearly identical to that of humans. He brings these apes to life on every page, revealing their personalities, relationships and power struggles, creating an engrossing narrative that explores what their behaviour can teach us about ourselves and each other.

Amy Vedder leads a wild life. How many people can say they were once a member of a mountain gorilla family? Amy Vedder is a wildlife biologist, a scientist who studies animals and their behavior. She uses her knowledge to save animals whose lives and habitats are threatened. She once lived in a remote part of central Africa, where she helped rescue Rwanda's mountain gorillas from extinction. Amy did groundbreaking science in a beautiful rain forest environment, but it wasn't always easy. She had to face tough conditions in a country affected by conflict and war. In the process, she met unforgettable people and unforgettable gorillas. Today Amy travels the world, from her home base at New York's Bronx Zoo to the far reaches of Mongolia in Asia. Everywhere she goes, she teaches people how to appreciate and protect the precious wildlife that surrounds them. Gorilla Mountain is an exciting and inspiring story of true tale adventure. Young readers everywhere will be moved by the story of the young nature lover who became a powerful champion of great apes.

As our closest primate relatives, chimpanzees offer tantalizing clues about the behavior of early human ancestors. This book provides a rich and detailed portrait of chimpanzee social life in the wild, synthesizing hundreds of thousands of hours of research at seven long-term field sites. Why are the social lives of males and females so different? Why do groups of males sometimes seek out and kill neighboring individuals? Do chimpanzees cooperate when they hunt monkeys? Is their vocal behaviour like human speech? Are there different chimpanzee 'cultures'? Addressing these questions and more, Adam Arcadi presents a fascinating introduction to the chimpanzee social universe and the challenges we face in trying to save this species from extinction. With extensive notes organized by field site and an appendix describing field methods, this book is indispensable for students, researchers, and anyone else interested in the remarkable and complex world of these intelligent apes.
