This book was released on 2003 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: The focus of this thesis is the use of sound for communication by the North Atlantic right whale (Eubalaena glacialis). The surface active group (SAG) is the predominant social interaction in this species for which use of sound has been documented. Different group compositions in SAGs indicate that both potentially reproductive and non-reproductive groups have been combined under one label. Sound production in SAGs suggests that females form and maintain the groups by producing Scream calls. Males produce Upcalls to advertise their presence as they come into a group or when the female is on a dive. Males may use Gunshot sounds as threat signals to other males in the group or potentially as reproductive advertisement signals to the female. Some calves produce Warble sounds in SAGs. This may be limited to female calves. This description of acoustic activity in the groups adds to the picture of the SAGs as complex interactions between individuals, rather than simple groups with only one whale producing all the sounds to attract other whales to the group. Playback experiments demonstrate that right whales can use sounds from SAGs to locate the groups. Male right whales approached both North Atlantic and Southern right whale SAG playbacks. Female right whales only approached Southern right whale playbacks. Anatomical modeling resulted in a frequency range of hearing for the right whale (10 Hz - 22 kHz) that is consistent with the sounds that they produce and overlaps the frequency range of most anthropogenic noise sources. This combination of research provides a thorough description how North Atlantic right whales use sound in SAGs and how increasing levels of noise in the oceans may impact right whales in these groups.

Download or read book Conservation Physiology written by Christine L. Madliger and published by Oxford University Press. This book was released on 2020-11-30 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conservation physiology is a rapidly expanding, multidisciplinary field that utilizes physiological knowledge and tools to understand and solve conservation challenges. This novel text provides the first consolidated overview of its scope, purpose, and applications, with a focus on wildlife. It outlines the major avenues and advances by which conservation physiology is contributing to the monitoring, management, and restoration of wild animal populations. This book also defines opportunities for further growth in the field and identifies critical areas for future investigation. By using a series of global case studies, contributors illustrate how approaches from the conservation physiology toolbox can tackle a diverse range of conservation issues including the monitoring of environmental stress, predicting the impact of climate change, understanding disease dynamics, improving captive breeding, and reducing human-wildlife conflict. Moreover, by acting as practical road maps across a diversity of sub-disciplines, these case studies serve to increase the accessibility of this discipline to new researchers. The diversity of taxa, biological scales, and ecosystems highlighted illustrate the far-reaching nature of the discipline and allow readers to gain an appreciation for the purpose, value, applicability, and status of the field of conservation physiology. Conservation Physiology is an accessible supplementary textbook suitable for graduate students, researchers, and practitioners in the fields of conservation science, eco-physiology, evolutionary and comparative physiology, natural resources management, ecosystem health, veterinary medicine, animal physiology, and ecology.

Available in PDF, EPUB and Kindle. Book excerpt: "Marine scientist Michael J. Moore says we are all whalers, but we don't have to be. Eating fish leads to North Atlantic right whales' entanglement and death. Buying goods made around the world requires global shipping routes, which do not accurately consider right whale breeding and feeding sites, leading to collision. To explain this, Moore conveys to readers scenes from over thirty years' worth of fieldwork, performing whale necropsies for animals stranded on beaches, working as an independent researcher alongside whalers using explosive harpoons, and tracking injured pregnant whales to deliver antibiotics. Despite these sometimes disturbing experiences, Moore has written a hopeful book. He uses these stories to show we can change and to tell us how; the technology for rope-less fishing and tracking whale migrations already exist to protect both right whales and the people who depend on shipping and fishing for their livelihoods"--

Available in PDF, EPUB and Kindle. Book excerpt: In this book, an international team of leading marine mammal scientists, with a remarkably diverse set of backgrounds and areas of expertise, lead you through a synthesis of current knowledge on baleen whales. Baleen whales are the largest animals ever to have lived on this planet. They also have the lowest and most intense voices on Earth, most likely evolved to take advantage of ocean acoustic transmission conditions so as to be detectable across ocean basins. Some baleen whales can live to be 150-200 years old. They migrate many thousands of kilometers between feeding and breeding areas. They produce songs and calls that serve as behavioral foundations for establishing, maintaining and expanding their cultural identities. To conclude that we know the behavioral limits of these large brained, long-lived animals would be naïve. As baleen whale scientists, we are still beginning to comprehend the enormous complexities and natural histories of these remarkable animals. Today, the fact that whales sing is known throughout much of the world. This awareness started 50 years ago with the publication and popularization of a collection of humpback song recordings that motivated research into baleen whale behavioral ethology. In this book’s chapters, a reader’s experiences will stretch from learning about baleen whale laryngeal anatomy associated with their different voices to learning about the vast ocean areas over which their voices can be heard and the emerging complexities of their culturally defined societies. These are accompanied by chapters on the fundamental ethological contexts of socializing, migrating, and foraging. Two common themes permeate the book. One theme highlights the phenomenal increase in scientific knowledge achieved through technological advancements. The other theme recognizes the impacts of human-made activities on ocean acoustic environments and the resultant influences on the health and survival of individual whales and their populations. Although the book is intentionally ambitious in its scope, as scientists, we fully recognize that baleen whale science is still in its infancy. Many profound revelations await discovery by cohorts of young, multi-talented explorers, some of whom are stretching their wings in this volume and some of whom are reading these scientific stories for the first time.
Download or read book North Atlantic Right Whales written by David W. Laist and published by JHU Press. This book was released on 2017-03-29 with total page 461 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fascinating story of North Atlantic right whales—from their evolutionary origin, through a thousand-year history of relentless pursuit by whalers, to ongoing efforts to rescue them from the brink of extinction. In the cold waters of the unforgiving North Atlantic Ocean, some of the heartiest humans of medieval days ventured out in search of whales. Through the centuries, people on both sides of the Atlantic became increasingly dependent on whale oil and other cetacean products. To meet this growing demand, whaling became ever more sophisticated and intense, leading to the collapse of what was once a seemingly inexhaustible supply of large cetaceans. Central to the whale's subsequent struggle for existence has been one species—the North Atlantic right whale. Conservationist David W. Laist now provides the first complete history of the North Atlantic right whale, from its earliest encounters with humans to its close brush with extinction, to its currently precarious yet hopeful status as a conservation icon. Favored by whalers because of their high yields of oil and superior baleen, these giants became known as "the right whale to hunt," and their numbers dwindled to a mere 100 individuals worldwide. Their dire status encouraged the adoption of a ban on hunting and a treaty that formed the International Whaling Commission. Recovery of the species, however, has proven elusive. Ship strikes and entanglement in commercial fishing gear have hampered herculean efforts to restore the population. Today, only about 500 right whales live along the US and Canadian Atlantic coasts—an improvement from the early twentieth century, but still a far cry from the thousands that once graced Atlantic waters. Laist's masterpiece features an incredible collection of photographs and artwork that give life to the fascinating history that unfolds in its pages. The result is a single volume that offers a comprehensive understanding of North Atlantic right whales, the role they played in the many cultures that hunted them, and our modern attempts to help them recover.
