Book Synopsis Primates and Cetaceans by : Juichi Yamagiwa
Download or read book Primates and Cetaceans written by Juichi Yamagiwa and published by Springer Science & Business Media. This book was released on 2013-11-20 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, the editors present a view of the socioecology of primates and cetaceans in a comparative perspective to elucidate the social evolution of highly intellectual mammals in terrestrial and aquatic environments. Despite obvious differences in morphology and eco-physiology, there are many cases of comparable, sometimes strikingly similar patterns of sociobehavioral complexity. A number of long-term field studies have accumulated a substantial amount of data on the life history of various taxa, foraging ecology, social and sexual relationships, demography, and various patterns of behavior: from dynamic fission–fusion to long-term stable societies; from male-bonded to bisexually bonded to matrilineal groups. Primatologists and cetologists have come together to provide four evolutionary themes: (1) social complexity and behavioral plasticity, (2) life history strategies and social evolution, (3) the interface between behavior, demography, and conservation, and (4) selected topics in comparative behavior. These comparisons of taxa that are evolutionarily distant but live in comparable complex sociocognitive environments boost our appreciation of their sophisticated mammalian societies and can advance our understanding of the ecological factors that have shaped their social evolution. This knowledge also facilitates a better understanding of the day-to-day challenges these animals face in the human-dominated world and may improve the capacity and effectiveness of our conservation efforts.

Book Synopsis Swimming with Orca by : Ingrid Visser
Download or read book Swimming with Orca written by Ingrid Visser and published by Penguin Global. This book was released on 2005 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Meet the woman whose life revolves around orca, or killer whales. This book tells the fascinating story of Dr Ingrid Visser, a marine scientist who has spent the past ten years studying these creatures. During this time she has got to know many New Zealand orca intimately; she calls them her friends and can identify some by sight. Ingrid has a hands-on approach to her study - getting into the water with them, watching them hunt and interacting in any way she can. Ingrid is the only person to work with orca in the South Pacific and has discovered many differences between their behaviour here and in the northern hemisphere. The book is packed with interesting facts about orca in New Zealand and also tells Ingrid's own personal story and the inspiring encounters she has had with these intriguing animals.
Download or read book Transients written by John K.B. Ford and published by UBC Press. This book was released on 2011-11-01 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on transient killer whales. Enigmatic and elusive, these mammal-hunting whales are difficult animals to study. They travel in small groups, often moving unpredictably, which makes them less conspicuous than the larger resident pods. For these and other reasons, our understanding of the life history and ecology of transient killer whales has lagged behind that of residents. Transients contains the latest information on the natural history of transient killer whales, including their feeding habits, social lives, and distribution patterns. The catalogue section contains photographs of and notes on over 200 individual whales. Numerous sidebars contain interesting observations on encounters with transients as well as information on how and where to best watch them.

Book Synopsis Approaches to Understanding the Cumulative Effects of Stressors on Marine Mammals by : National Academies of Sciences, Engineering, and Medicine
Download or read book Approaches to Understanding the Cumulative Effects of Stressors on Marine Mammals written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2017-05-04 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine mammals face a large array of stressors, including loss of habitat, chemical and noise pollution, and bycatch in fishing, which alone kills hundreds of thousands of marine mammals per year globally. To discern the factors contributing to population trends, scientists must consider the full complement of threats faced by marine mammals. Once populations or ecosystems are found to be at risk of adverse impacts, it is critical to decide which combination of stressors to reduce to bring the population or ecosystem into a more favorable state. Assessing all stressors facing a marine mammal population also provides the environmental context for evaluating whether an additional activity could threaten it. Approaches to Understanding the Cumulative Effects of Stressors on Marine Mammals builds upon previous reports to assess current methodologies used for evaluating cumulative effects and identify new approaches that could improve these assessments. This review focuses on ways to quantify exposure-related changes in the behavior, health, or body condition of individual marine mammals and makes recommendations for future research initiatives.
Book Synopsis Global Change in Marine Systems by : Patrice Guillotreau
Download or read book Global Change in Marine Systems written by Patrice Guillotreau and published by Routledge. This book was released on 2017-11-13 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global Change in Marine Systems analyses and appraises societal and governing responses to change affecting marine social and ecological systems around the world. Acknowledging the stakes – local societies that depend on marine systems for food, livelihoods and wellbeing can suffer great hardship – this book highlights and explains similarities and distinctions between successful and unsuccessful responses. The book presents an analytical framework (‘I-ADApT’) that enables decision-makers to consider possible responses to global change based on experiences elsewhere. Here an international group of researchers from the natural and social sciences apply the ‘I-ADApT’ framework to twenty enlightening case studies, covering a wide range of marine systems challenged by critical global change issues around the world. The innovative research presented here guides marine system researchers, policymakers, decision-makers and practitioners in responding to global change in a timely and appropriate manner. It will appeal to students and researchers interested in environmental studies, natural resources, marine resources, environmental sociology, sustainability, and climate change.
Book Synopsis Marine Mammals and Noise by : W. John Richardson
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.

Book Synopsis Marine Mammal Populations and Ocean Noise by : National Research Council
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.
