Available in PDF, EPUB and Kindle. Book excerpt: "Part review, part testament to extraordinary dedication, and part call to get involved, Cetacean Societies highlights the achievements of behavioral ecologists inspired by the challenges of cetaceans and committed to the exploration of a new world."—from the preface by Richard Wrangham Long-lived, slow to reproduce, and often hidden beneath the water's surface, whales and dolphins (cetaceans) have remained elusive subjects for scientific study even though they have fascinated humans for centuries. Until recently, much of what we knew about cetaceans came from commercial sources such as whalers and trainers for dolphin acts. Innovative research methods and persistent efforts, however, have begun to penetrate the depths to reveal tantalizing glimpses of the lives of these mammals in their natural habitats. Cetacean Societies presents the first comprehensive synthesis and review of these new studies. Groups of chapters focus on the history of cetacean behavioral research and methodology; state-of-the-art reviews of information on four of the most-studied species: bottlenose dolphins, killer whales, sperm whales, and humpback whales; and summaries of major topics, including group living, male and female reproductive strategies, communication, and conservation drawn from comparative research on a wide range of species. Written by some of the world's leading cetacean scientists, this landmark volume will benefit not just students of cetology but also researchers in other areas of behavioral and conservation ecology as well as anyone with a serious interest in the world of whales and dolphins. Contributors are Robin Baird, Phillip Clapham, Jenny Christal, Richard Connor, Janet Mann, Andrew Read, Randall Reeves, Amy Samuels, Peter Tyack, Linda Weilgart, Hal Whitehead, Randall S. Wells, and Richard Wrangham.

This book was released on 2015 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cetacean populations are confronted by many anthropogenic threats, including commercial whaling, noise, vessel collisions, gear entanglement, exploitative competition, habitat disturbance, and global climate change. Evidence indicates that commercial fishing activities can have both direct (e.g., gear entanglement and bycatch) and indirect (e.g., prey reduction and noise) effects on cetaceans. However, few studies have addressed the potential vulnerability of a given cetacean species to an entire fishing fleet that operates over a large marine ecosystem. In this study, we overlaid spatially explicit multiyear predicted mean densities of 11 cetacean species and 1 species guild within the California Current Large Marine Ecosystem with data for commercial fishing effort of the fixed-gear, at-sea hake mid-water trawl, and bottom trawl fleets of the west coast groundfish fishery. We quantified the exposure of each species to each fleet type by multiplying the predicted mean cetacean density by the measured fishing fleet effort. We found large interspecific and interfleet variability in the overlap between cetaceans and fishing fleets. Although many of the species had relatively low overlap rates, others had substantial exposure to some of the fishing fleets, particularly those species with more nearshore distributions. Direct mortality from these fleets has been documented to be low, but our results indicate that there is opportunity for fisheries interactions with some cetacean species, particularly in the fixed-gear fleet. Our analyses make up an important first step in generating formal risk assessments for quantification of the impacts of various fishing fleets on populations of cetacean species that occur in the California Current.

The objective of this volume is to provide a snapshot of this explosion. The volume paints the scene with a broad brush. Taken together the chapters clearly indicate that cetacean origins is a field that is dynamic, multidisciplinary, and that the end of the explosive phase is not in sight.

Download or read book Whales Dolphins Porpoises written by Annalisa Berta and published by University of Chicago Press. This book was released on 2015-10-15 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: The eighty-nine cetacean species that swim our seas and rivers are as diverse as they are intelligent and elusive, from the hundred-foot-long, two-hundred-ton blue whale to the lesser-known tucuxi, ginkgo-toothed beaked whale, and diminutive, critically endangered vaquita. The huge distances these highly migratory creatures cover and the depths they dive mean we catch only the merest glimpses of their lives as they break the surface of the water. But thanks to the marriage of science and technology, we are now beginning to understand their anatomy, complex social structures, extraordinary communication abilities, and behavioral patterns. In this beautifully illustrated guide, renowned marine mammalogist Annalisa Berta draws on the contributions of a pod of fellow whale biologists to present the most comprehensive, authoritative overview ever published of these remarkable aquatic mammals. Opening with an accessible rundown of cetacean biology—including the most recent science on feeding, mating, and communication—Whales, Dolphins, and Porpoises then presents species-specific natural history on a range of topics, from anatomy and diet to distribution and conservation status. Each entry also includes original drawings of the species and its key identifiers, such as fin shape and color, tooth shape, and characteristic markings as they would appear both above and below water—a feature unique to this book. Figures of myth and—as the debate over hunting rages on—figures of conflict since long before the days of Moby-Dick, whales, dolphins, and porpoises are also ecologically important and, in many cases, threatened. Written for general enthusiasts, emergent cetacean fans, and biologists alike, this stunning, urgently needed book will serve as the definitive guide for years to come.

Book excerpt: Cetaceans are one of the most unknown groups in the animal kingdom. Their study is very difficult due to their scarcity, their flighty behavior, and their enormous displacements. In addition, some species feed in very deep waters and only emerge to breathe, or they live in hard to reach areas. However, few animals create so much wonder. What child or adult has not felt emotions when contemplating the spectacles of the killer whales, the pirouettes of the dolphins, or the immensity of the whales in the middle of the sea? Some of the authors of this book have been so moved to be surrounded by a group of fin whales that could not contain their tears. It is a difficult sensation to explain. One could try to summarize it by saying that these immense animals exhale peace. Seeing dolphins making capers around a boat or a group of fin whales suddenly emerging a few meters away is one of the greatest shows we can see in nature. In the presence of these animals, there is only a feeling of recollection. These are the moments when we see how small we humans are in this wonderful biosphere. Therefore, this book is a small tribute to these beautiful living beings. Something we owe them. We have to protect these animals, but we cannot do so without knowing them. In this text, the authors provide key information to understand the evolution of cetaceans, their patterns of movement and behavior, always under a conservation perspective.This book has been written by 15 leading specialists from three different countries and with different backgrounds ranging from biology to veterinary science. They are united by a common interest, a passion. The book does not focus on a single species, but covers studies with dolphins, sperm whales, and fin whales, as well as various methodological approaches that provide key data to understand the evolution of up to 50 different species. Many diverse aspects have been covered and, above all, new methodological approaches have been provided in areas such as acoustics, the study of spatial and feeding behavior, evolution, social interactions, and even blue economics. As if this were not enough, the authors wish to highlight the immense amount of data that has been used. The first chapter on fin whales is based on hundreds of sightings over several years, and dozens of satellite images on various environmental parameters. Chapter two covers hundreds of recordings of the sounds of humpback whales around the world. Chapter three has followed the sperm whale populations of the Strait of Gibraltar over several years with hundreds of sightings. Chapters four and five study the evolution of more than fifty species through hundreds of recordings using qualitative and quantitative approaches, respectively. The sixth chapter compares the behavior of two species of dolphins. Finally, chapter seven designs a new line of study for these animals: the blue economy.

Download or read book Marine Protected Areas for Whales Dolphins and Porpoises written by Erich Hoyt and published by Routledge. This book was released on 2012-10-02 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first edition of the widely praised Marine Protected Areas for Whales, Dolphins and Porpoises, published in 2005, led to numerous new marine protected area proposals and a number of notable conservation successes around the world. In this completely revised and expanded second edition, new developments in the Mediterranean, Caribbean and Pacific are described, as well as future directions for High Seas protection. New sections show how to design and manage MPAs in an ever noisier ocean subject to climate change, increased shipping and hydrocarbon exploration. The process of protected area creation for cetaceans has been accelerated and more than 200 exciting new places are detailed in this edition. This book provides a route map for MPA managers, as well as countries, to meet the ambitious targets for highly protected MPA networks by 2012 and 2020. This book is a key conservation tool and a springboard for worldwide change in human attitudes toward the world ocean where all life originated and where the majority of life on Earth still lives.
