This booklet will not only enable you to identify what you find in the pellets of British owls but also shows how the data may be usefully presented and how to estimate the actual weight of food the birds have eaten.
Dolphins have become one of the ocean's most sought-after creatures. Since antiquity, Dolphins have possessed an undeniable, mysterious and compelling allure for humankind, which in recent years has intensified, inspiring everything from New Age fervour to multi-million dollar theme parks. In our profit-driven age, suppliers are never far behind demand, and having discovered people will eagerly pay exorbitant sums for the opportunity to get close, lucrative captive "Dolphin-swim" attractions have sprung up in many tropical vacation destinations. A recent BBC poll found "Swimming with Dolphins" topping the list of "50 Things To Do Before You Die." Rekindling the Waters: The Truth About Swimming with Dolphins is an intimate expos of this popular phenomenon, illuminating the little-known dark side of this increasingly controversial activity. What really lies behind the dolphins' smile may surprise you. Dolphins are among the world's most beloved and beleaguered creatures and a closer look reveals the shocking truth: how a whimsical or well-earned holiday excursion to swim with captive Dolphins can support horrendous suffering. An examination of the latest scientific research regarding Dolphin behaviour, intelligence, self-awareness and culture is presented, and this rich and diverse evidence raises dynamic ethical questions, eliciting a call for change in the way we regard and treat our fellow beings. Hope lies in shifting the underlying attitudes responsible for our participation in such harmful activities. As people realize the detrimental reality, it is hoped these harmful activities will cease. Rekindling the Waters: The Truth About Swimming with Dolphins is essential reading for anyone who loves dolphins. With Dolphins as a symbol for Nature, this book shows us that by rekindling a wiser and more respectful relationship with them, we take a vital step toward a better, kinder world.
Dolphins are smart. They are so smart that they can talk to each other. Dolphins communicate underwater for the same reason people talk on land: to let others know who they are, where they are, and maybe even how to feel. Also included are activities that explore how dolphins talk to each other.

The water shrew is one of our least known but most intriguing mammals. The Water Shrew Handbook is the first guide to British water shrews and covers their biology, ecology and conservation. It includes the latest national distribution maps from the Mammal Society's water shrew survey, and advice on carrying our local studies.
From familiar terrapins basking on a log to the majestic long-lived giant tortoises, turtles are among the most fascinating animals on the planet. In this complete guide to the world's 300 species of turtles, the authors reveal intimate, little-known details of these intriguing reptiles in their native habitats: what they eat, where they live, how they behave, and when and where they lay their eggs. The authors have travelled the world extensively together to study turtles in their natural habitats and have produced a comprehensive and beautifully written book that will appeal to all turtle lovers and nature enthusiasts. It is magnificently illustrated with over 300 colour photographs and each species has a colour distribution map. This book will be the standard reference on the subject for years to come.
For over thirty years, rodents have been used in the study of many human and animal diseases. The rat in particular continues to serve as an experimental model for drug safety and efficacy tests for the treatment of neurological disorders, heart disease, diabetes, breast, liver and other cancers. With the more recent advent of transgenic technology, an impressive amount of new knowledge about transmissible spongiform encephalopathies has been accumulated. It is likely that the principles learned from the study of these prion diseases will be applicable to elucidating the causes of more common neurodegenerative disorders such as Alzheimerís and Parkinsonís diseases. As a result of this and, more importantly, because of increasingly complicated legislation governing the use of animals in regulated procedures, there is a need for experimenters (both experienced and those new to the laboratory) to improve their skills continuously and to become au fait with all aspects of preparatory techniques. The Rat Nervous System provides an accessible guide to the dissection and perfusion of rats, placing particular emphasis on the preparation of nervous tissue for further study in the laboratory including biochemical analysis and microscopic study. Logically structured with highly illustrated chapters covering gross anatomy, anatomy of the nervous system, anaesthesia, biological fixation and tissue extraction, the book provides a comprehensive introduction to those techniques required to provide consistent, high-quality tissues for subsequent investigation. Animal husbandry of a high standard, together with minimisation of discomfort, is essential if the information sought by the investigator is to be valid and reproducible; an overview of these topics is therefore also incorporated in this volume.
The Teeth of Non-Mammalian Vertebrates is the first comprehensive publication devoted to the teeth and dentitions of living fishes, amphibians and reptiles. The book presents a comprehensive survey of the amazing variety of tooth forms among non-mammalian vertebrates, based on descriptions of approximately 400 species belonging to about 160 families. The text is lavishly illustrated with more than 600 high-quality color and monochrome photographs of specimens gathered from top museums and research workers from around the world, supplemented by radiographs and micro-CT images. This stimulating work discusses the functional morphology of feeding, the attachment of teeth, and the relationship of tooth form to function, with each chapter accompanied by a comprehensive, up-to-date reference list. Following the descriptions of the teeth and dentitions in each class, four chapters review current topics with considerable research activity: tooth development; tooth replacement; and the structure, formation and evolution of the dental hard tissues. This timely book, authored by internationally recognized teachers and researchers in the field, also reflects the resurgence of interest in the dentitions of non-mammalian vertebrates as experimental systems to help understand genetic changes in evolution of teeth and jaws.
This groundbreaking book on shorebirds examines the taxonomy, appearance, behavior, ecology, and conservation of Golden and Grey Plovers, and compares and contrasts their natural history and biogeography. It gives detailed accounts on all aspects of their lifestyle including feeding, mating, parental care, moults, migration, and avoidance of predators. The authors' first hand experiences add to its value. "Tundra Plovers explores the differences in plumage, vocalizations, habitat use, breeding, movements, and food. The connections between phylogeny, biogeography, and behavior will be of interest because the authors have focussed on the differences between the sexes as well as the four species. Byrkjedal has also contributed all of the wonderful color and line illustrations. More than 40 photographs, 150 tables and figures, and many other embellishments complete this definitive book.

From "one of the world's greatest experts on primate behavior" (Desmond Morris) comes a look at the most provocative aspects of human nature-power, sex, violence, kindness, and morality-through our closest cousins. For nearly twenty years, Frans De Waal has studied both the famously aggressive chimpanzee and the egalitarian, matriarchal bonobo, two species whose DNA is nearly identical to ours. The result is an engrossing narrative that reveals what their behavior can teach us about ourselves.
