The object of this book is to introduce ethology to agricultural and veterinary students. Today ethology covers many approaches to the study of animal behaviour which are connected by one unifying concept: all behaviour must be considered in relation to the ecology and evolutionary history of the species under investigation. This may seem to some to put domesticated animals beyond the scope of classical ethology but, while domestication has involved some behavioural changes, we shall see that much of the behaviour of our species of farm livestock differs little from that of their putative ancestors. It is assumed that students using this book will already have studied some physiology. It is also assumed that they are, essentially, practically minded and with this factor in mind I have discussed behaviour in terms of its function, introducing the principles of ethology within functional categories of behaviour. In order to best illustrate these principles I have taken examples from a variety of species and not confmed myself to farm livestock and domestic animals, for fundamental ethological research with these species has been patchy. However at the end of each chapter I have given a list of papers pertaining to farm livestock so that the principles of ethology can be seen in a more practical context and to develop this approach further I have also added some practical problems for discussion at the end of each chapter.

This book is a contribution to the history of ethology-not a definitive history, but the personal view of a major figure in that story. It is all the more welcome because such a grand theme as ethology calls for a range of perspectives. One reason is the overarching scope of the subject. Two great questions about life that constitute much of biology are "How does it work (structure and function)?" and "How did it get that way (evolu tion and ontogeny)?" Ethology addresses the antecedent of "it. " Of what are we trying to explain the mechanism and development? Surely behav ior, in all its wealth of detail, variation, causation, and control, is the main achievement of animal evolution, the essential consequence of animal structure and function, the raison d' etre of all the rest. Ethology thus spans between and overlaps with the ever-widening circles of ecol ogy over the eons and the ever-narrowing focus of physiology of the neurons. Another reason why the history of ethology needs perspectives is the recency of its acceptance. For such an obviously major aspect of animal biology, it is curious how short a time-less than three decades-has seen the excitement of an active field and a substantial fraternity of work ers, the addition of professors and courses to departments and curricula in biology (still far from universal}, and the normal complement of spe cial journals, symposia, and sessions at congresses.

Conceptual Breakthroughs in Ethology and Animal Behavior highlights, through concise summaries, the most important discoveries and scientific revolutions in animal behavior. These are assessed for their relative impact on the field and their significance to the forward motion of the science of animal behavior. Eighty short essays capture the moment when a new concept emerged or a publication signaled a paradigm shift. How the new understanding came about is explained, and any continuing controversy or scientific conversation on the issue is highlighted. Behavior is a rich and varied field, drawing on genetics, evolution, physiology, and ecology to inform its principles, and this book embraces the wealth of knowledge that comes from the unification of these fields around the study of animals in motion. The chronological organization of the essays makes this an excellent overview of the history of animal behavior, ethology, and behavioral ecology. The work includes such topics as Darwin's role in shaping the study of animal behavior, the logic of animal contests, cognition, empathy in animals, and animal personalities. Succinct accounts of new revelations about behavior through scientific investigation and scrutiny reveal the fascinating story of this field. Similar to Dr. John Avise's Contemporary Breakthroughs in Evolutionary Genetics, the work is structured into vignettes that describe the conceptual revolution and assess the impact of the conceptual change, with a score, which ranges from 1-10, providing an assessment of the impact of the new findings on contemporary science. - Features a lively, brisk writing style and brief entries to enable easy, enjoyable access to this essential information - Includes topics that cover the range of behavioral biology from mechanism to behavioral ecology - Can also be used as supplemental material for an undergraduate animal behavior course, or as the foundational text for an upper level or graduate discussion course in advanced animal behavior

Principles of Animal Behavior has long been considered the most current and engaging introduction to animal behavior. The Third Edition is now also the most comprehensive and balanced in its approach to the theoretical framework behind how biologists study behavior.

'A book rich and various in ideas and substance...It belongs on the shelf of anyone wanting to keep up with what is happening in ethology.'-Bioscience, from a review of an earlier volume Beginning with Volume 11, Nicholas S. Thompson takes over the editorship of this remarkable series. For this volume, contributors bring fresh perspectives to the subject of natural design.

With the discovery of conditioned reflexes by I. P. Pavlov, the possibilities for experimenting, following the example set by the classical, exact sciences, were made available to the behavioral sciences. Many psychologists hoped that the component parts of behavior had also been found from which the entire, multifaceted cosmos of behavior could then be constructed. An experimentally oriented psychology subsequently developed including the influential school of behaviorism.This first text on human ethology presents itself as a unified work, even though not every area could be treated with equal depth. For example, a branch of ethology has developed in the past decade which places particular emphasis on ecology and population genetics. This field, known as sociobiology, has enriched discussion beyond the boundaries of behavioral biology through its stimulating, and often provocative, theses.After vigorous debates between behaviorists, anthropologists, and sociologists, we have entered a period of exchange of thoughts and a mutual approach, which in many instances has led to cooperative projects of researchers from different disciplines. This work offers a biological point of view for discussion and includes data from the author's cross-cultural work and research from the staff of his institute. It confirms, above all else, the astonishing unity of mankind and paints a basically positive picture of how we are moved by the same passions, jealousies, friendliness, and active curiosity.The need to understand ourselves has never been as great as it is today. An ideologically torn humanity struggles for its survival. Our species, does not know how it should compensate its workers, and it experiments with various economic systems, constitutions, and forms of government. It struggles for freedom and stumbles into newer conflicts. Population growth is apparently completely out of hand, and at the same time many resources are being depleted. We must consider our existence rati

Ethology, the study of the biology of behavior, has grown tremendously during the last few decades. The large number of accumulated facts is difficult to survey, understanding and an appreciation of the ethological approach to the study of behavior have grown, and the number of attempts at holistic explanations for certain behavioral phenomena has increased. Because of this development it has become more difficult to gain an overview of the field, to keep up with new developments, and to update the subject matter by the inclusion of new facts in the proper place. The nonspecialist is unable to evaluate the more general statements in the popular literature, especially when such works are aimed at a broader audience. Hence, this book has a dual purpose: (1) to lend some order to the dizzying array of information and thus simplify inquiry into ethology; and (2) to present relevant facts and knowledge that will help the reader confronted with numerous studies and articles in the ethological literature.

Chickens are by far the world’s most widely farmed animal, kept for both meat and egg production. They are at the centre of many debates regarding housing and production systems, causing significant interest in what lies behind chicken behaviour. This accessible book covers sensory biology, behavioural development, preferences and aversions, social behaviour, learning and cognition, behavioural issues in different systems and solutions for behavioural problems. Authored by an authority on chicken ethology, it brings together the fields of animal behaviour, neuroscience, psychology and epidemiology to provide a comprehensive understanding of chicken behaviour and help improve the lives of farmed chickens around the world.
