Book excerpt: The purpose of the peer review meeting summarized in this report was to proceed with a recovery potential assessment for 4 beluga populations designated as at risk under the Species at Risk Act (SARA). The 4 beluga populations are the Cumberland Sound, the Saint Lawrence Estuary, the Ungava Bay and the Eastern Hudson Bay populations. The 1st part of the meeting focussed on the development of interim descriptions of the biological properties of suitable recovery targets and recovery times that could be applied to beluga populations of concern. The 2nd part of the meeting addressed the recovery potential assessment for each beluga population.

Download or read book Biology of Marine Mammals written by John E. Reynolds and published by Smithsonian Institution. This book was released on 1999-09-17 with total page 589 pages. Available in PDF, EPUB and Kindle. Book excerpt: Taking an integrated approach to the biology of marine carnivores, cetaceans, and sirenians, twenty-two prominent researchers compare marine mammals with one another and with terrestrial mammals, providing a framework for fundamental biological and ecological concepts. They describe functional morphology, sensory systems, energetics, reproduction, communication and cognition, behavior, distribution, population biology, and feeding ecology. They also detail the physiological adaptations—for such activities and processes as diving, thermo-regulation, osmoregulation, and orientation—that enable marine mammals to exploit their aquatic environment.

Book excerpt: The Atlantic Walrus: Multidisciplinary insights into human-animal interactions addresses the key dimensions of long-term human walrus interactions across the Atlantic Arctic and subarctic regions, over the past millennia. This book brings together research from across the social and natural sciences to explore walrus biology, human culture, environmental conditions and their reciprocal effects. Together, 13 chapters of this book reconstruct the early evolution of walruses, walrus biology, the cultural significance and ecological impact of prehistoric and indigenous hunting practices, as well as the effects of commercial hunting and international trade. This book also examines historic and ongoing management strategies and, the importance of new research methodologies in revealing hitherto unknown details of the past, and concludes by discussing the future for Atlantic walruses in the face of climate change and increased human activities in the Arctic. This volume is an ideal resource for those who are seeking to understand an iconic Arctic species and its long and complex relationship with humans. This includes individuals and researchers with a personal or professional connection to walruses or the Arctic, as well as marine biologists, zoologists, conservationists, paleontologists, archaeologists, anthropologists, historians, indigenous communities, natural resource managers and government agencies. - Provides succinct overviews of the biology of the Atlantic Walrus (Odobenus rosmarus rosmarus) as well as human cultures within the North Atlantic Arctic and the surrounding region by consolidating research which until now has been scattered across fields and academic publications - Editorial team of inter-disciplinary researchers ensuring the breadth, depth and integration of material covered throughout the volume - Thirteen chapters, each authored by leading international researchers and experts on the Atlantic Walrus - Considers the inter-relatedness and complexity of species biology, ecological change, human culture, and anthropogenic pressures onto the Atlantic Walrus, all while remaining accessible to readers from different disciplines or a more generalist audience - Draws upon the latest methods in marine mammal and archaeological research - Assesses historical management of the species, while also considering current and future conservation efforts in light of human activities and climate change - Text supported by striking and insightful new maps and scientific illustrations, ideal for teaching and outreach
Download or read book Marine Mammals and Noise written by W. John Richardson and published by Academic Press. This book was released on 2013-10-22 with total page 593 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many marine mammals communicate by emitting sounds that pass through water. Such sounds can be received across great distances and can influence the behavior of these undersea creatures. In the past few decades, the oceans have become increasingly noisy, as underwater sounds from propellers, sonars, and other human activities make it difficult for marine mammals to communicate. This book discusses, among many other topics, just how well marine mammals hear, how noisy the oceans have become, and what effects these new sounds have on marine mammals. The baseline of ambient noise, the sounds produced by machines and mammals, the sensitivity of marine mammal hearing, and the reactions of marine mammals are also examined. An essential addition to any marine biologist's library, Marine Mammals and Noise will be especially appealing to marine mammalogists, researchers, policy makers and regulators, and marine biologists and oceanographers using sound in their research.

Available in PDF, EPUB and Kindle. Book excerpt: The Bering Sea, which lies between the United States and Russia, is one of the most productive ecosystems in the world and has prolific fishing grounds. Yet there have been significant unexplained population fluctuations in marine mammals and birds in the region. The book examines the Bering Sea ecosystem's dynamics and the relationship between man and the ecosystem, in order to identify potential reasons for the population fluctuations as well as identify ways the Sea's living resources can be better managed by government.
Download or read book A Little Less Arctic written by Steven H. Ferguson and published by Springer Science & Business Media. This book was released on 2010-05-30 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Arctic Canada, Hudson Bay is a site of great exploration history, aboriginal culture, and a vast marine wilderness supporting large populations of marine mammals and birds. These include some of the most iconic Arctic animals like beluga, narwhal, bowhead whales, and polar bears. Due to the challenges of conducting field research in this region, some of the mysteries of where these animals move, and how they are able to survive in such seemingly inhospitable, ice-choked habitats are just now being unlocked. For example, are polar bears being replaced by killer whales? This new information could not be more salient, as the Hudson Bay Region is undergoing rapid environmental change due to global warming, as well as increased pressures from industrial development interests. A Little Less Arctic brings together some of the world’s leading Arctic scientists to present the current state of knowledge on the physical and biological characteristics of Hudson Bay.
