Download or read book Echolocation in Bats and Dolphins written by Jeanette A. Thomas and published by University of Chicago Press. This book was released on 2004 with total page 636 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although bats and dolphins live in very different environments, are vastly different in size, and hunt different kinds of prey, both groups have evolved similar sonar systems, known as echolocation, to locate food and navigate the skies and seas. While much research has been conducted over the past thirty years on echolocation in bats and dolphins, this volume is the first to compare what is known about echolocation in each group, to point out what information is missing, and to identify future areas of research. Echolocation in Bats and Dolphins consists of six sections: mechanisms of echolocation signal production; the anatomy and physiology of signal reception and interpretation; performance and cognition; ecological and evolutionary aspects of echolocation mammals; theoretical and methodological topics; and possible echolocation capabilities in other mammals, including shrews, seals, and baleen whales. Animal behaviorists, ecologists, physiologists, and both scientists and engineers who work in the field of bioacoustics will benefit from this book.
Download or read book Animal Sonar written by Paul E. Nachtigall and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 822 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first meeting on biosonar that I had the opportunity to attend was held in 1978 on the Island of Jersey in the English Channel. That meeting, organized by Professor R.G. Busne1 and Dr. Jim Fish, was my introduction to an exciting and varied group of hard-working and dedicated scientists studying animal echolocation. They are, by nature, a very diverse group. They tend to publish in different journals and rarely interact despite the fact that they all work on echolocation. When they do interact as a group, as they did in Frascati Italy in 1966, in Jersey i~ 1978, and during the meeting reported in this volume, the meetings are intense, interesting, and exciting. This volume is a composition of a series of contributed papers written to foster an interdisciplinary understanding of the echolocation systems of animals. The echolocation pulse production studies in bats and dolphins have recently been concentrated on the ontogeny of infant pulses, other studies, with three-dimensional computer graphics and x-ray computed tomography, have concentrated on finally resolving the old controversy concerning the site of dolphin echolocation click production. Much has been accomplished on the analysis of bat neural structure and function. The intense effort directed toward understanding the structure, connections, and functional properties of parallel auditory pathways and the parallel and hierarchical processing of information by the mustached bat, has lead to dramatic breakthroughs in understanding brain function.
Download or read book Biosonar written by Annemarie Surlykke and published by Springer. This book was released on 2014-07-19 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two groups of animals, bats and odontocetes (toothed whales), have independently developed the ability to orient and detect prey by biosonar (echolocation). This active mechanism of orientation allows these animals to operate under low light conditions. Biosonar is a conceptual overview of what is known about biosonar in bats and odontocetes. Chapters are written by bat and odontocetes experts, resulting in collaborations that not only examine data on both animals, but also compare and contrast mechanisms. This book provides a unique insight that will help improve our understanding of biosonar in both animal groups.

Download or read book Animal Sonar Systems written by R. Busnel and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 1097 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Voices in the Ocean written by Susan Casey and published by Anchor. This book was released on 2015-08-04 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: NEW YORK TIMES BESTSELLER • Inspired by a profound experience swimming with wild dolphins off the coast of Maui, the bestselling author of The Wave set out on a quest to learn everything she could about dolphins—the other intelligent life on the planet. “Part science, part memoir, part impassioned plea for change.” —People Susan Casey’s journey takes her from a community in Hawaii known as “Dolphinville,” where the animals are seen as the key to spiritual enlightenment, to the dark side of the human-cetacean relationship at marine parks and dolphin-hunting grounds in Japan and the Solomon Islands, to the island of Crete, where the Minoan civilization lived in harmony with dolphins, providing a millennia-old example of a more enlightened coexistence with the natural world. Along the way, Casey recounts the history of dolphin research and introduces us to the leading marine scientists and activists who have made it their life’s work to increase humans’ understanding and appreciation of the wonder of dolphins.
Download or read book Dolphin Mysteries written by Kathleen M. Dudzinski and published by Yale University Press. This book was released on 2008-10-14 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dolphins have fascinated humans for millennia, giving rise to an abundance of stories and myths about them, yet the actual details of their lives in the sea have remained elusive. In this enthralling book, Kathleen M. Dudzinski and Toni Frohoff take us into the dolphins' aquatic world to witness firsthand how they live their lives, communicate, and interact with one another and with other species, including people. Kathleen M. Dudzinski and Toni Frohoff are scientists who have collectively dedicated more than 40 years to studying dolphins beneath the ocean's surface, frequently through a close-up underwater lens. Drawing on their own experiences and on up-to-the-minute research, the authors show that dolphins are decidedly not just members of a group but distinct individuals, able to communicate with one another and with humans. Dudzinski and Frohoff introduce a new way of looking at, and listening to, the vocabulary of dolphins in the sea, and they even provide an introductory "dolphin dictionary," listing complex social signals that dolphins use to share information among themselves and with people. Unveiling an intimate and scientifically accurate portrait of dolphins, this book will appeal to everyone who has wanted a closer glimpse into the hearts and minds of these amazing creatures.

Download or read book Souls in the Sea written by Scott Taylor and published by North Atlantic Books. This book was released on 2003-02-21 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dolphins have long been attributed with intelligence, but do they have souls? Self-awareness? Compassion? Scott Taylor, Director of the Cetacean Studies Institute, investigates the history, mythology, and science surrounding these creatures and emerges with a resounding yes. And not only do whales and dolphins merit our attention and respect in their own right: they are an index to what our future as a species can be. In this multi-faceted cetology compendium, Taylor surveys the portrayal of dolphins and whales in works of literature as disparate as Moby Dick and Sumerian legend, examines biologist John Lilly's research on interspecies communication, and explores the benefits of dolphin-assisted swimming therapy for disabled children and adults. Looking at the world from the perspective of one of these "souls in the sea," Taylor suggests that cetaceans are an ideal bridge between humanity and nature. Poetically written and thoughtfully illustrated with photos and drawings, Souls in the Sea is a comprehensive celebration of the biology, history, and mystique of dolphins and whales.
Download or read book War of the Whales written by Joshua Horwitz and published by Simon and Schuster. This book was released on 2014-07-01 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Winner of the 2015 PEN/E.O. Wilson Literary Science Writing Award: “Horwitz’s dogged reporting…combined with crisp, cinematic writing, produces a powerful narrative…. He has written a book that is instructive and passionate and deserving a wide audience” (PEN Award Citation). Six years in the making, War of the Whales is the “gripping detective tale” (Publishers Weekly) of a crusading attorney, Joel Reynolds, who stumbles on one of the US Navy’s best-kept secrets: a submarine detection system that floods entire ocean basins with high-intensity sound—and drives whales onto beaches. As Joel Reynolds launches a legal fight to expose and challenge the Navy program, marine biologist Ken Balcomb witnesses a mysterious mass stranding of whales near his research station in the Bahamas. Investigating this calamity, Balcomb is forced to choose between his conscience and an oath of secrecy he swore to the Navy in his youth. “War of the Whales reads like the best investigative journalism, with cinematic scenes of strandings and dramatic David-and-Goliath courtroom dramas as activists diligently hold the Navy accountable” (The Huffington Post). When Balcomb and Reynolds team up to expose the truth behind an epidemic of mass strandings, the stage is set for an epic battle that pits admirals against activists, rogue submarines against weaponized dolphins, and national security against the need to safeguard the ocean environment. “Strong and valuable” (The Washington Post), “brilliantly told” (Bob Woodward), author Joshua Horwitz combines the best of legal drama, natural history, and military intrigue to “raise serious questions about the unchecked use of secrecy by the military to advance its institutional power” (Kirkus Reviews, starred review).

Download or read book To Free a Dolphin written by Keith Coulbourn and published by Renaissance Books. This book was released on 2015-10-06 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this memorable first book, Behind the Dolphin Smile, Richard O'Barry told the inspiring story of his personal transformation from world-famous dolphin trainer (Flipper was his pupil) to dolphin liberator. Now, in To Free a Dolphin, he passionately recounts the dramatic story of his heart-breaking campaign to release captive dolphins back into the wild. With wit and insight he chronicles the extreme opposition he has faced from bureaucrats, major players in the captive-dolphin industry, rival wildlife groups, and well-meaning sentimentalists. He introduces readers to famous show animals he has helped, including Bogie and Bacall of Key Largo. And, most fascinating, he describes his struggles to deprogram and rehabilitate dolphins emotionally scarred from years of captivity--struggles that become battles for the animals' souls.

Download or read book Before We Leave You written by Patricia Cori and published by North Atlantic Books. This book was released on 2011-04-26 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: What if whales and dolphins truly do have a superior intellect, as many believe, and can speak to the human race? What would their message be? In November 2008, gifted clairvoyant Patricia Cori was in Jordan teaching a workshop when a life-changing event occurred. A community of Cetaceans—“a choir of whales and dolphins,” as she describes it—interrupted her talk with a frantic plea for help. Cori was suddenly witness to a devastating scene of suffering, a communal grieving of scores of whales and dolphins “frenzied, lost, and dying.” This was the first of several terrifying calls for help, all of which were immediately followed by mass suicide events as these majestic creatures collectively chose to leave us and our planet. These troubling incidents evolved into the stream of messages for humanity that Cori reveals in this extremely timely work. The whales and dolphins present their deep understanding of our urgent global situation, calling for the human race to restore balance to our ecosystems—especially our dying oceans. For the first time, we read the communications of the Cetaceans and their story of devotion and celebration of life on the Great Planet Earth. We are also given a glimpse of their role in the unfolding of galactic events throughout our solar system, and the message is clear: We must wake up and realize that our continued abuse of the environment is altering the course of Gaia’s progression to the next dimension. Without the whale and dolphin song—without these musicians who hold the oceans in balance—we risk our advancement through the ascension process for which our entire solar system is destined. Before We Leave You is a roadmap to that higher future and a pathway to global transformation. ***NOTE: ELECTRONIC VERSION OF THIS TITLE DOES NOT INCLUDE THE CETACEAN MEDITATIONS CARDS INCLUDED IN THE REGULAR PRINTED VERSION.
