This book was released on 2007 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Ship strike mortality remains one of the two primary causes of lack of recovery of the North Atlantic population of northern right whales (Eubalaena glacialis). As a result, NOAA fisheries has identified a number of actions to reduce interactions between ships and whales. Central to this approach is the concept that ship strike mortality can be reduced either by slowing ships or by separating vessels and whales." p.1.

Download or read book Physiology of Marine Mammals written by Michael Castellini and published by CRC Press. This book was released on 2023-07-05 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: Suppose you were designing a marine mammal. What would they need to live in the ocean? How would you keep them warm? What design features would allow them to dive for very long periods to extreme depths? Do they need water to drink? How would they minimize the cost of swimming, and how would they find their prey in the deep and dark? These questions and more are examined in detail throughout Marine Mammal Physiology, which explores how marine mammals live in the sea from a physiological point of view. This undergraduate textbook considers the essential aspects of what makes a marine mammal different from terrestrial mammals, beyond just their environment. It focuses on the physiological and biochemical traits that have allowed this group of mammals to effectively exploit the marine environment that is so hostile to humans. The content of this book is organised around common student questions, taking the undergraduate's point of view as the starting point. Each chapter provides a set of PowerPoint slides for instructors to use in teaching and students to use as study guides. New "Study Questions" and "Critical Thinking Points" conclude each chapter, which are each motivated by a "Driving Question" such as "How do mammals stay warm in a cold ocean?" or "How do mammals survive the crushing pressures of the deep sea?" Full-colour images and comprehensive, accessible content make this the definitive textbook for marine mammal physiology.
Download or read book The Urban Whale written by Scott D. Kraus and published by Harvard University Press. This book was released on 2007-02-15 with total page 624 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1980 a group of scientists censusing marine mammals in the Bay of Fundy was astonished by the sight of 25 right whales. Until that time, scientists believed the North Atlantic right whale was extinct or nearly so. The sightings electrified the research community, spurring a quarter century of exploration, which is documented here.

Download or read book Acoustic Communication in the North Atlantic Right Whale Eubalaena Glacialis written by Susan Elizabeth Parks and published by . 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 We Are All Whalers written by Michael J. Moore and published by University of Chicago Press. This book was released on 2021-11-12 with total page 234 pages. 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: 'Erich Hoyt's handbook is an admirable, timely and highly welcome contribution.'Michael Stachowitsch, Marine EcologyWhat does it mean to save the whales if their habitat is left unprotected? Marine Protected Areas for Whales, Dolphins and Porpoises is the definitive handbook on this pressing issue and the first to bridge the gap between the disciplines of marine protected areas and cetacean conservation. It launches a new chapter in cetacean conservation with its investigation into the crucial habitat needs and protection requirements of some 84 species.The author, one of the world's foremost experts in this field, takes you around the world to investigate the promising results of the latest conservation research and the strategies for obtaining marine protected areas in coastal waters and on the high seas, using national legislation and regional and international conventions. This is an essential introduction, guide and reference work for those working to ensure a future for whales and dolphins.

Download or read book Marine Mammal Welfare written by Andy Butterworth and published by Springer. This book was released on 2017-06-19 with total page 625 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine mammals attract human interest – sometimes this interest is benign or positive – whale watching, conservation programmes for whales, seals, otters, and efforts to clear beaches of marine debris are seen as proactive steps to support these animals. However, there are many forces operating to affect adversely the lives of whales, seals, manatees, otters and polar bears – and this book explores how the welfare of marine mammals has been affected and how they have adapted, moved, responded and sometimes suffered as a result of the changing marine and human world around them. Marine mammal welfare addresses the welfare effects of marine debris, of human traffic in the oceans, of noise, of hunting, of whale watching and tourism, and of some of the less obvious impacts on marine mammals – on their social structures, on their behaviours and migration, and also of the effects on captivity for animals kept in zoos and aquaria. There is much to think and talk about – how marine mammals respond in a world dramatically influenced by man, how are their social structures affected and how is their welfare impacted?

Download or read book Marine Mammal Populations and Ocean Noise written by National Research Council and published by National Academies Press. This book was released on 2005-01-24 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: Attention has been drawn to the subject of how ocean noise affects marine mammals by a series of marine mammal strandings, lawsuits, and legislative hearings, and most recently, the report from the U.S. Commission on Ocean Policy. One way to assess the impact of ocean noise is to consider whether it causes changes in animal behavior that are "biologically significant," that is, those that affect an animal's ability to grow, survive, and reproduce. This report offers a conceptual model designed to clarify which marine mammal behaviors are biologically significant for conservation purposes. The report is intended to help scientists and policymakers interpret provisions of the federal Marine Mammal Protection Act.
