This collection of essays was written by former students, associates, admirers, critics and friends of Donald R. Griffin -- the creator of cognitive ethology. Stimulated by his work, this volume presents ideas and experiments in the field of cognitive ethology -- the exploration of the mental experiences of animals as they behave in their natural environment during the course of their normal lives. Cognitive Ethology discusses the possibility that animals may have abilities to experience, communicate, reason, and plan beyond those usually ascribed to them in a "black box" or "stimulus-response" interpretation of their behavior. Contributions from scientists who have been associated with or influenced by Griffin offer a lively array of views, some disparate from one another and some especially selected to present approaches contrary to his.

Genetics and the Behavior of Domestic Animals, Third Edition offers the latest and most valuable information on animal science and behavioral genetics, carrying on the book's legacy since its original publication in 1998. This book synthesizes research from behavioral genetics and animal and veterinary science, bridging the gap between these fields. The objective is to show that principles of behavioral genetics have practical applications to agricultural and companion animals. The continuing domestication of animals is a complex process whose myriad impacts on animal behavior are commonly under-appreciated. Genetic factors play a significant role in both species-specific behaviors and behavioral differences exhibited by individuals in the same species. Leading authorities explore the impact of increased intensities of selection on domestic animal behavior. Rodents, cattle, pigs, sheep, horses, herding and guard dogs, and poultry are all included in these discussions of genetics and behavior, making this book useful to veterinarians, livestock producers, laboratory animal researchers and technicians, animal trainers and breeders, and any researcher interested in animal behavior. Genetics and the Behavior of Domestic Animals, Third Edition is the most valuable resource for researchers and practitioners in animal and veterinary science, animal behavior, genetics, ethology, and similar fields. Advanced undergraduate and graduate students in these disciplines will also benefit from the global expertise featured in this newest edition. - Provides full and thorough updates to all chapters, ensuring dissemination of the latest data and research - Synthesizes research from behavioral genetics, animal science, and veterinary literature - Broaches fields of behavior genetics and behavioral research - Includes practical applications of principles discovered by behavioral genetics researchers - Covers many species ranging from pigs, dogs, foxes, rodents, cattle, horses, and cats

In these classic experiments, quail chicks were selectively bred for the behavioral traits of fear and social reinstatement. Over a period of 20 generations, four separate genetic lines were created. They were high and low fear and high and low social re-instatement. The duration of tonic immobility was used as a measure of fear and social reinstatement was measured with a treadmill test. In this test, the time that a bird will walk on a treadmill to stay close to its flockmates is measured. Since the publication of this chapter in 1998, many scientists have carried out with these genetic lines. Duration of tonic immobility does not all measure all types of fear. Fear maybe multidimensional because selection for tonic immobility has little effect on behavioral reactions to novelty. More recent research has also discovered linked traits such as low social reinstatement birds have stronger ultradiam rhythms.
