The illegal trade in live apes, ape meat and body parts occurs across all ape range states and poses a significant and growing threat to the long-term survival of wild ape populations worldwide. What was once a purely subsistence and cultural activity, now encompasses a global multi-million-dollar trade run by sophisticated trans-boundary criminal networks. The challenge lies in teasing apart the complex and interrelated factors that drive the ape trade, while implementing strategies that do not exacerbate inequality. This volume of State of the Apes brings together original research and analysis with topical case studies and emerging best practices, to further the ape conservation agenda around killing, capture and trade. This title is also available as Open Access via Cambridge Core.

Although much is known about the anatomy of adult primates, particularly chimpanzees, the same cannot be said for the anatomy of young primates, especially non-hominoid primates such as lemurs and marmosets. This is the first book dedicated to newborn skeletal and dental anatomy and how it varies across primate species, which is important for interpreting adult primate skeletal form, as well as for comprehending primate and human evolution. Structured according to anatomical regions, the book includes hundreds of detailed anatomical illustrations, a color atlas illustrating entire skeletons in representative taxa, and boxes at the end of each chapter providing further detail on key aspects covered in the main text. Whilst the book is primarily a guide to comparative anatomy, it also highlights the links between development and behavior. An indispensable resource for students and researchers in the fields of biological anthropology, anatomy, primatology, growth and development, dental biology, and veterinary medicine.

Visitors cannot help but be enchanted by the sea lions of Los Islotes. They emanate finesse and charm without a hint of illusion or wizardry. There is no incantation or voodoo, just an abounding sense of play that inspires every visitor. When it comes to wild animal encounters, Los Islotes is almost nirvana. Few places so close to a city can truly offer such a convenient and accessible opportunity to interact with Mother Nature in her untamed state. California sea lions are the main residents, strangely thriving in a place so accessible to tourists. Initial introductions begin at the surface; encounters are then formalized below the water as Poseidon's ocean ambassadors exuberantly whiz towards and around diver and snorkeler alike. With vivid underwater photography throughout by a uniquely positioned author, The Sea Lions of Los Islotes takes readers straight into the world of these most charismatic marine mammals.

Nearly half the world's primate species use flooded habitats at one time or another, from swamp-going Congo gorillas and mangrove-eating proboscis monkeys, to uacaris in Amazonian riverside forests. This first-ever volume on the subject brings together experts from around the world in a ground breaking volume spanning fossil history, current biology and future research and conservation priorities. Flooded habitats are a vital part of tropical biology, both for the diversity of the species they house, and the complexity of their ecological interactions, but are often completely overlooked. This book will set the stage for a new wave of research on primates in these extraordinarily productive and highly threatened areas, and is ideal for researchers and graduate students in primatology, zoology, ecology, and conservation.

This volume brings together some of the best known and respected experts in the field of marine mammal biology to provide a cohesive and accessible text. A very broad scope of topics and examples are classified as marine mammals; the whales, dolphins and porpoises (cetaceans), seals, sea lions, fur seals and walruses (pinnipeds), manatees and dugongs (sirenians), and the sea otter and polar bear (carnivores). Topics covered include diversity, distribution and evolutionary patterns, anatomical and physiological adaptations, vocal and social behaviour, problem solving and memory, feeding ecology and energetics, life history and reproductive strategies, patterns of movement and population genetics, and conservation and management. Chapters are fully cross-referenced and illustrated, and the citations are numerous and current. All chapters are united by the theme of evolutionary context, addressing the question of how these diverse mammalian species have adapted to life in the oceans. The intended audience includes students of marine biology, ecology and evolution, as well as professionals with an interest in marine mammals, evolutionary pattern and process, zoology and ecology.

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.
