Narwhals - Arctic Whales in a Melting World (Paperback): Todd McLeish Narwhals - Arctic Whales in a Melting World (Paperback)
Todd McLeish
R568 Discovery Miles 5 680 Ships in 12 - 17 working days

Among all the large whales on Earth, the most unusual and least studied is the narwhal, the northernmost whale on the planet and the one most threatened by global warming. Narwhals thrive in the fjords and inlets of northern Canada and Greenland. These elusive whales, whose long tusks were the stuff of medieval European myths and Inuit legends, are uniquely adapted to the Arctic ecosystem and are able to dive below thick sheets of ice to depths of up to 1,500 meters in search of their prey-halibut, cod, and squid. Join Todd McLeish as he travels high above the Arctic circle to meet: Teams of scientific researchers studying the narwhal's life cycle and the mysteries of its tusk Inuit storytellers and hunters Animals that share the narwhals' habitat: walruses, polar bears, bowhead and beluga whales, ivory gulls, and two kinds of seals McLeish consults logbooks kept by whalers and explorers and interviews folklorists and historians to tease out the relationship between the real narwhal and the mythical unicorn. In Colorado, he visits climatologists studying changes in the seasonal cycles of the Arctic ice. From a history of the trade in narwhal tusks to descriptions of narwhals' vocalizations as heard through hydrophones, Narwhals reveals the beauty and thrill of the narwhal and its habitat, and the threat it faces from a rapidly changing world.

Sperm Whales (Paperback, New): Hal Whitehead Sperm Whales (Paperback, New)
Hal Whitehead
R1,212 Discovery Miles 12 120 Ships in 12 - 17 working days

Famed in story as "the great leviathans," sperm whales are truly creatures of extremes. Giants among all whales, they also have the largest brains of any creature on Earth. Males can reach a length of sixty-two feet and can weigh upwards of fifty tons.
With this book, Hal Whitehead gives us a clearer picture of the ecology and social life of sperm whales than we have ever had before. Based on almost two decades of field research, Whitehead describes their biology, behavior, and habitat; how they organize their societies; and how their complex lifestyles may have evolved in this unique environment. Among the many fascinating topics he explores is the crucial role that culture plays in the life of the sperm whale, and he traces the consequences of this argument for both evolution and conservation. Finally, drawing on these findings, Whitehead builds a general model of how the ocean environment influences social behavior and cultural evolution among mammals as well as other animals.
The definitive portrait of a provocative creature, "Sperm Whales" will interest animal behaviorists, conservationists, ecologists, and evolutionary biologists as well as marine mammalogists.

Bernd Wursig
R5,421 Discovery Miles 54 210 Ships in 10 - 15 working days

This book concentrates on the marine mammalian group of Odontocetes, the toothed whales, dolphins, and porpoises. In 23 chapters, a total of 40 authors describe general patterns of ethological concepts of odontocetes in their natural environments, with a strong bent towards behavioral ecology. Examples are given of particularly well-studied species and species groups for which enough data exist, especially from the past 15 years. The aim is to give a modern flavor of present knowledge of ethology and behavior of generally large-brained behaviorally flexible mammals that have evolved quite separately from social mammals on land. As well, the plight of populations and species due to humans is described in multiple chapters, with the goal that an understanding of behavior can help to solve or alleviate at least some human-made problems.

Touching This Leviathan asks how we might come to know the unknowable--in this case, whales, these animals so large yet so elusive, revealing just a sliver of back, a glimpse of a fluke, or, if you're lucky, a split-second breach before diving away. It's a pressing question, given how frequently whales are in the news: Japan just withdrew from the International Whaling Commission's ban on whaling; the Makah Tribe seeks to resume hunts; in 2019 there was a rash of dead gray whales along the west coast (some 200 of them); in 2018, an orca attracted international attention when she pushed her dead calf through the water 17 days before finally letting go. But other whale books sit in disciplinary silos: the history books, the science books, the literary books. There's no conversation between them, which is where Touching This Leviathan intervenes. Drawing upon biology, theology, local history, literary studies, environmental studies, and composition theory, Touching This Leviathan is necessarily interdisciplinary: literary nonfiction that gestures toward science and literary criticism as it invites readers into the belly of the whale.

Vaquita - Science, Politics, and Crime in the Sea of Cortez (Hardcover, 2nd None ed.): Brooke Bessesen Vaquita - Science, Politics, and Crime in the Sea of Cortez (Hardcover, 2nd None ed.)
Brooke Bessesen
R862 Discovery Miles 8 620 Ships in 12 - 17 working days

In 2006, vaquita, a diminutive porpoise making its home in the Upper Gulf of California, inherited the dubious title of world’s most endangered marine mammal. Nicknamed “panda of the sea” for its small size and beguiling facial markings, vaquita have been in decline for decades, dying by the hundreds in gillnets intended for the commercially valuable fish, totoaba. When international crime cartels discovered a lucrative trade in the swim bladders of totoaba, illegal gillnetting went rampant, and now the lives of the few remaining vaquita hang in the balance. Author Brooke Bessesen takes us on a journey to Mexico’s Upper Gulf region to uncover the story. She interviewed townspeople, fishermen, politicians, scientists, and activists, teasing apart a complex story filled with villains and heroes, a story whose outcome is unclear. When diplomatic and political efforts to save the little porpoise failed, Bessesen traveled with a team of veterinary experts in a binational effort to capture the remaining ten vaquita and breed them in captivity—the only hope for their survival. In this fast-paced, soul-searing tale, she learned that there are no easy answers when extinction is profitable. Whether the rescue attempt succeeds or fails, the world must ask itself hard questions. When vaquita and the totoaba are gone, the black market will turn to the next vulnerable species. What will we do then?

The Walking Whales - From Land to Water in Eight Million Years (Paperback): J. G. M. "Hans" Thewissen The Walking Whales - From Land to Water in Eight Million Years (Paperback)
J. G. M. "Hans" Thewissen
R841 R692 Discovery Miles 6 920 Save R149 (18%) Ships in 12 - 17 working days

Hans Thewissen, a leading researcher in the field of whale paleontology and anatomy, gives a sweeping first-person account of the discoveries that brought to light the early fossil record of whales. As evidenced in the record, whales evolved from herbivorous forest-dwelling ancestors that resembled tiny deer to carnivorous monsters stalking lakes and rivers and to serpentlike denizens of the coast. Thewissen reports on his discoveries in the wilds of India and Pakistan, weaving a narrative that reveals the day-to-day adventures of fossil collection, enriching it with local flavors from South Asian culture and society. The reader senses the excitement of the digs as well as the rigors faced by scientific researchers, for whom each new insight gives rise to even more questions, and for whom at times the logistics of just staying alive may trump all science. In his search for an understanding of how modern whales live their lives, Thewissen also journeys to Japan and Alaska to study whales and wild dolphins. He finds answers to his questions about fossils by studying the anatomy of otters and porpoises and examining whale embryos under the microscope. In the book's final chapter, Thewissen argues for approaching whale evolution with the most powerful tools we have and for combining all the fields of science in pursuit of knowledge.

Freshwater Biodiversity - Status, Threats and Conservation (Paperback): David Dudgeon Freshwater Biodiversity - Status, Threats and Conservation (Paperback)
David Dudgeon
R1,309 Discovery Miles 13 090 Ships in 12 - 17 working days

Growing human populations and higher demands for water impose increasing impacts and stresses upon freshwater biodiversity. Their combined effects have made these animals more endangered than their terrestrial and marine counterparts. Overuse and contamination of water, overexploitation and overfishing, introduction of alien species, and alteration of natural flow regimes have led to a 'great thinning' and declines in abundance of freshwater animals, a 'great shrinking' in body size with reductions in large species, and a 'great mixing' whereby the spread of introduced species has tended to homogenize previously dissimilar communities in different parts of the world. Climate change and warming temperatures will alter global water availability, and exacerbate the other threat factors. What conservation action is needed to halt or reverse these trends, and preserve freshwater biodiversity in a rapidly changing world? This book offers the tools and approaches that can be deployed to help conserve freshwater biodiversity.

Passive Acoustic Monitoring of Cetaceans (Paperback): Walter M. X. Zimmer Passive Acoustic Monitoring of Cetaceans (Paperback)
Walter M. X. Zimmer
R1,466 Discovery Miles 14 660 Ships in 12 - 17 working days

Passive acoustic monitoring is increasingly used by the scientific community to study, survey and census marine mammals, especially cetaceans, many of which are easier to hear than to see. PAM is also used to support efforts to mitigate potential negative effects of human activities such as ship traffic, military and civilian sonar and offshore exploration. Walter Zimmer provides an integrated approach to PAM, combining physical principles, discussion of technical tools and application-oriented concepts of operations. Additionally, relevant information and tools necessary to assess existing and future PAM systems are presented, with Matlab code used to generate figures and results so readers can reproduce data and modify code to analyse the impact of changes. This allows the principles to be studied whilst discovering potential difficulties and side effects. Aimed at graduate students and researchers, the book provides all information and tools necessary to gain a comprehensive understanding of this interdisciplinary subject.

R3,095 Discovery Miles 30 950 Ships in 12 - 17 working days

Within little more than a generation, whale-watching has been subject to global industrial development. It has been portrayed by destinations and business operators, and advocated by environmental groups, as a sustainable activity and an alternative to whaling. However, in recent years the sustainability of these activities has increasingly been questioned, as research shows that repeated disturbance by boat traffic can severely disrupt critical behaviours of cetaceans in the wild. Bringing together contributions by international experts, this volume addresses complex issues associated with commercial whale-watching, sustainable development and conservation of the global marine environment. It highlights widely expressed concerns for the failure of policy, planning and management and pinpoints both long-standing and emerging barriers to sustainable practice. Featuring numerous case studies, the book provides critical insights into the diverse socio-cultural, political, economic and ecological contexts of this global industry, highlighting the challenges and opportunities that arise along the pathways to sustainability.

In the songs and bubble feeding of humpback whales; in young killer whales learning to knock a seal from an ice floe in the same way their mother does; and in the use of sea sponges by the dolphins of Shark Bay, Australia, to protect their beaks while foraging for fish, we find clear examples of the transmission of information among cetaceans. Just as human cultures pass on languages and turns of phrase, tastes in food (and in how it is acquired), and modes of dress, could whales and dolphins have developed a culture of their very own? Unequivocally: yes. In The Cultural Lives of Whales and Dolphins, cetacean biologists Hal Whitehead, who has spent much of his life on the ocean trying to understand whales, and Luke Rendell, whose research focuses on the evolution of social learning, open an astounding porthole onto the fascinating culture beneath the waves. As Whitehead and Rendell show, cetacean culture and its transmission are shaped by a blend of adaptations, innate sociality, and the unique environment in which whales and dolphins live: a watery world in which a hundred-and-fifty-ton blue whale can move with utter grace, and where the vertical expanse is as vital, and almost as vast, as the horizontal. Drawing on their own research as well as a scientific literature as immense as the sea--including evolutionary biology, animal behavior, ecology, anthropology, psychology, and neuroscience--Whitehead and Rendell dive into realms both humbling and enlightening as they seek to define what cetacean culture is, why it exists, and what it means for the future of whales and dolphins. And, ultimately, what it means for our future, as well.

True river dolphins as well as marine dolphins that frequent freshwater systems are large animals that have traditionally gone unnoticed by the general public and, in a certain sense, by marine mammal specialists as well. In fact, only a limited number of researchers have investigated the biology of these dolphin species. This is quite surprising given that these species are commonly the top predators in their habitats. Now for the first time, revolutionary molecular techniques are being applied to answer evolutionary reconstruction questions of many animals, including river dolphins. In addition, new paleontological records are dramatically changing our perspective about the relationships of these dolphins with each other and with other cetaceans. In this book, new census information and important ecological characteristics are provided of the river dolphins Inia, Sotalia, Pontoporia, Lioptes, and Orcaella. For the first time, molecular and genetic results of theses dolphin species are presented. A compilation of these data is essential if we are to present a strategic conservation plan for these animals. Upon being informed of critical evolutionary historical data, conservation biologists will now be able to tailor their conservation efforts for each threatened river dolphin species. Additionally, new morphological data and the new discoveries in the fossil record for river dolphins are examined. The major dolphin specialists in Colombia, Brazil, Bolivia, Argentina, the United States of America, China, and India present their newest results within a single book that graduate students, professors, scientists, evolutionary ecologists, aquatic mammalogists, population ecologists, conservation ecologists, and marine biologists will all find valuable for the foreseeable future.

The synthesis of the Aquatic Biodiversity and Ecosystems Conference (ABEC) 2015, which was held to assess scientific progress over the past twnety-five years, this book provides a comprehensive and global review of work since the 1992 publication of Plant-Animal Interactions in the Marine Benthos. Taking a regional and, where appropriate, habitat perspective, it considers sites of coastal biodiversity from around the world to incorporate a global approach. The volume analyses abiotic and biotic interactions, and the factors determining distribution patterns, community structure and ecosystem functioning of coastal systems. It explores themes of how phylogeography and biogeographic process influence assemblage composition, and hence drive community structure and the respective roles of environmental factors and biological interactions, with the overall goal to establish how general are the processes in different regions and habitats. For researchers, graduate students and academics studying coastal ecosystems, with interest for conservation practitioners managing areas of high biodiversity.

Looking to the vast human history of water worship, a crucial study of our broken relationship with all things aquatic - and how we might mend it. Early human relationships with water were expressed through beliefs in serpentine aquatic deities: rainbow-coloured, feathered or horned serpents, giant anacondas and dragons. Representing the powers of water, these beings were bringers of life and sustenance, world creators, ancestors, guardian spirits and law makers. Worshipped and appeased, they embodied people's respect for water and its vital role in sustaining all living things. Yet today, though we still recognise that 'water is life', fresh- and saltwater ecosystems have been critically compromised by human activities. This major study of water beings, and what has happened to them in different cultural and historical contexts, demonstrates how and why some - but not all - societies have moved from worshipping water to wreaking havoc upon it, and asks what we can do to turn the tide. 'A far-ranging and gorgeously illustrated study, Water Beings explores humanity's enduring but always transforming connections to the wellsprings of life. A profound and entertaining book for a time when reimagining humanity's future has never been more vital.' - Caspar Henderson, author of The Book of Barely Imagined Beings 'With passion, rigor and creative depth, Strang eloquently takes readers across the world to further our understanding of water's natural, cultural, and symbolic qualities. Water beings are brought to life alongside relational beliefs and practices. This is a magnificent work that reflects a rich human/water/culture relationship, and explores possibilities to avoid a climate crisis future.' - Sandy Toussaint, University of Western Australia 'A spellbinding anthropological itinerary through the winding ways of serpentine water beings as they have manifested through history and across cultures. Luminously illustrated, ingeniously researched, and beautifully narrated, Strang's book is a treasure, a store of revelatory stories about how materiality, meaning, and myth have intertwined to create the aqueous spirits and deities that have accompanied human being and becoming.' - Stefan Helmreich, Elting E.

"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.
