Book Description
Thirteen years have gone by since the first international meet ing on Animal Sonar Systems was held in Frascati, Italy, in 1966. Since that time, almost 900 papers have been published on its theme. The first symposium was vital as it was the starting point for new research lines whose goal was to design and develop technological systems with properties approaching optimal biological systems. There have been highly significant developments since then in all domains related to biological sonar systems and in their appli cations to the engineering field. The time had therefore come for a multidisciplinary integration of the information gathered, not only on the evolution of systems used in animal echolocation, but on systems theory, behavior and neurobiology, signal-to-noise ratio, masking, signal processing, and measures observed in certain species against animal sonar systems. Modern electronics technology and systems theory which have been developed only since 1974 now allow designing sophisticated sonar and radar systems applying principles derived from biological systems. At the time of the Frascati meeting, integrated circuits and technol ogies exploiting computer science were not well enough developed to yield advantages now possible through use of real-time analysis, leading to, among other things, a definition of target temporal char acteristics, as biological sonar systems are able to do. All of these new technical developments necessitate close co operation between engineers and biologists within the framework of new experiments which have been designed, particularly in the past five years.

Book Description
Cetaceans (whales, dolphins, and porpoises) have fascinated and bewildered humans throughout history. Their mammalian affinities have been long recognized, but exactly which group of terrestrial mammals they descend from has, until recently, remained in the dark. Recent decades have produced a flurry of new fossil cetaceans, extending their fossil history to over 50 million years ago. Along with new insights from genetics and developmental studies, these discoveries have helped to clarify the place of cetaceans among mammals, and enriched our understanding of their unique adaptations for feeding, locomotion and sensory systems. Their continuously improving fossil record and successive transformation into highly specialized marine mammals have made cetaceans a textbook case of evolution - as iconic in its own way as the origin of birds from dinosaurs. This book aims to summarize our current understanding of cetacean evolution for the serious student and interested amateur using photographs, drawings, charts and illustrations.

Book Description
In folktales told throughout much of the Brazilian Amazon, dolphins take human form, attend raucous dances and festivals, seduce men and women, and carry them away to a city beneath the river. They are encantados, or Enchanted Beings, capable of provoking death or madness, but also called upon to help shamanic healers. Male dolphins—accomplished dancers who appear dressed in dapper straw hats, white suits, and with shiny black shoes—reportedly father numerous children. The females are said to lure away solitary fishermen. Both sinister and charming, these characters resist definition and thus domination; greedy and lascivious outsiders, they are increasingly symbolic of a distinctly Amazonian culture politically, socially, economically, and environmentally under seige. Candace Slater examines these stories in Dance of the Dolphin, both as folk narratives and as representations of culture and conflict in Amazonia. Her engaging study discusses the tales from the viewpoints of genre, performance, and gender, but centers on them as responses to the great changes sweeping the Amazon today. According to Slater, these surprisingly widespread tales reflect Amazonians' own mixed reactions to the ongoing destruction of the rainforest and the resulting transformations in the social as well as physical landscape. Offering an informed view of Brazilian culture, this book crosses the boundaries of folklore, literature, anthropology, and Latin American studies. It is one of the very few studies to offer an overview of the changes taking place in Amazonia through the eyes of ordinary people. "This book is a rich collection of stories about the transformation of dolphins in the city of enchantment. . . . The joy in this book is not just its vibrant analysis and careful relating of tradition and lore, but also its uncanny accurateness in capturing the very essence of Amazonia."-Darrell Posey, Journal of Latin American Studies "Slater's fluid prose reads like a novel for those interested in Amazonian culture and folklore, while her integrated approach makes this a must read for those interested in innovative methodology."-Lisa Gabbert, Western Folklore
