Small Cetaceans of Japan - Exploitation and Biology (Paperback): Toshio Kasuya Small Cetaceans of Japan - Exploitation and Biology (Paperback)
Toshio Kasuya; Edited by William Perrin
R1,520 Discovery Miles 15 200 Ships in 10 - 15 working days

This book summarizes and analyzes the biology, ecology, exploitation and management of small cetaceans in Japan. It describes the various types of cetacean fisheries in Japan and their historical development, the life histories and ecologies of the main species involved, and the history and problems of conservation and management. The data show that in some cases the number of small cetaceans harvested exceed sustainable limits and have led to depletion of populations. The book provides a case study of what can go wrong when the needs of industry and conservation collide. The descriptions of life history and ecology are relevant to issues of conservation and management, not just for cetaceans, but for all fisheries around the world.

Florida Manatees - Biology, Behavior, and Conservation (Hardcover): John E. Reynolds Florida Manatees - Biology, Behavior, and Conservation (Hardcover)
John E. Reynolds; Photographs by Wayne Lynch
R947 Discovery Miles 9 470 Ships in 10 - 15 working days

Manatees, the gentle giants of Florida's lagoons and coastal habitats, can bring a smile to the face of anybody lucky enough to spy one. As manatees dip and roll through the water, crowds gather to watch them feed on aquatic vegetation. Whether they are congregating by the hundreds or resting or feeding alone, viewing these sea cows can provide anyone interested in nature with hours of tranquil pleasure. Having survived for eons, today's manatees are now under constant threat due to our rapidly swelling human population. Their habitats are often devastated by development and pollution. The slow-moving manatees also live at the mercy of chance, for they occupy waters filled with fast-moving boats powered by razor-sharp propellers-a new form of predator from which they have no protection. Boat speed limits have been put in place to protect manatees, but there is a constant push to lift them so that people can once again zip across the waters that manatees call home. For this reason, manatees are often a subject of controversy that pits their lives against the rights of boat owners. In this book, manatee expert John E. Reynolds III and famed photographer Wayne Lynch join forces to reveal the clearest portrait of manatees ever published. Florida Manatees is a song for the manatee, a celebration of the lives of these majestic creatures. Reynolds's concise, informative text shares what scientists know about manatees, while Lynch's beautiful photographs instantly demonstrate how special these "potatoes with whiskers" really are. By encouraging an appreciation of manatees, the authors hope to help ensure a future in which Floridians can find ways to coexist with and continue to enjoy these uniquely wonderful sirenian inhabitants of their state. Included in this book:* How manatees first came to Florida waters* How manatees fit into the ecosystems of Florida* What and how much manatees eat* How manatees behave and communicate with one another* Why manatees look the way they do* Why manatees have whiskers* How manatee mothers feed their young and much more

Introducing the Manatee (Hardcover): Warren Zeiller Introducing the Manatee (Hardcover)
Warren Zeiller
R833 Discovery Miles 8 330 Ships in 18 - 22 working days

This work is about the first manatee ever conceived and born in captivity. The pregnancy was long (about 13 months), the mother was huge (over 900 pounds), and baby Lorelei was regarded by Zeiller and his coworkers at the Miami Seaquarium as a truly blessed event. Even one addition to the dwindling number of this endangered species was reason to rejoice. Zeiller's knowledge of the history and plight of this docile sea mammal is based on his work at the Seaquarium, where he helped develop the only extant breeding herd of manatees (including Lorelei's parents, Romeo and Juliet), the only gene pool of the animal in captivity at that time. With more than 100 photographs that help to document his personal experiences, Zeiller describes ""mercy"" missions with the Mermaid Rescue Squad to liberate animals caught in drainage ditches or to care for animals injured by boat propellers. He relates his efforts and adventures with Captain Jacques Cousteau to return ""Sewer Sam"" to the freedom of Crystal River. In uncomplicated language he presents scientific information on the habitat, distribution, physiology, and feeding and breeding habits of the manatee and its relatives. Manatees are nearing extinction not because of public insensitivity, he believes, but because of a lack of knowledge. His intention throughout the book is to increase public awareness of the crises. ""Destroying or saving 60,000,000 years of evolution is in our hands"", he writes. And, from the Epilogue: ""We have named Lorelei's son (Juliet's grandson) Hugh.

RSPB Spotlight Seals (Paperback): Frances Dipper RSPB Spotlight Seals (Paperback)
Frances Dipper
R347 Discovery Miles 3 470 Ships in 10 - 15 working days

Seals are the sleekest and most agile of all marine mammals, and they are superbly adapted to the watery world in which they spend most of their time. With their whiskery dog-like faces, curious nature and vulnerable pups, they are enduringly appealing animals. Although air-breathing, seals are superbly tuned to hunt, sleep, mate and keep warm while out at sea, but they remain inextricably linked to land. In Spotlight Seals, Frances Dipper explores the intricate lives of the UK's native Grey and Common Seals and their amazing physical and behavioural adaptations to a life split between land and sea. She reveals the complex physiology that allows seals to dive deep and for long periods without coming to any harm. Once exploited for their meat and skins, seals now have protection around the British Isles. Their numbers are increasing, but they still face the danger of plastic litter in their environment. Dipper also explores age-old legends, interactions between humans and seals, and the best places to watch them in the UK. The Spotlight series introduces readers to the lives and behaviour of our favourite animals with eye-catching colour photographs and informative expert text.

Floating Gold - A Natural (and Unnatural) History of Ambergris (Paperback): Christopher Kemp Floating Gold - A Natural (and Unnatural) History of Ambergris (Paperback)
Christopher Kemp
R493 Discovery Miles 4 930 Ships in 9 - 17 working days

A fascinating natural history of an incredibly curious substance. "Preternaturally hardened whale dung" is not the first image that comes to mind when we think of perfume, otherwise a symbol of glamour and allure. But the key ingredient that makes the sophisticated scent linger on the skin is precisely this bizarre digestive by-product-ambergris. Despite being one of the world's most expensive substances (its value is nearly that of gold and has at times in history been triple it), ambergris is also one of the world's least known. But with this unusual and highly alluring book, Christopher Kemp promises to change that by uncovering the unique history of ambergris. A rare secretion produced only by sperm whales, which have a fondness for squid but an inability to digest their beaks, ambergris is expelled at sea and floats on ocean currents for years, slowly transforming, before it sometimes washes ashore looking like a nondescript waxy pebble. It can appear almost anywhere but is found so rarely, it might as well appear nowhere. Kemp's journey begins with an encounter on a New Zealand beach with a giant lump of faux ambergris-determined after much excitement to nothing more exotic than lard-that inspires a comprehensive quest to seek out ambergris and its story. He takes us from the wild, rocky New Zealand coastline to Stewart Island, a remote, windswept island in the southern seas, to Boston and Cape Cod, and back again. Along the way, he tracks down the secretive collectors and traders who populate the clandestine modern-day ambergris trade. Floating Gold is an entertaining and lively history that covers not only these precious gray lumps and those who covet them, but presents a highly informative account of the natural history of whales, squid, ocean ecology, and even a history of the perfume industry. Kemp's obsessive curiosity is infectious, and eager readers will feel as though they have stumbled upon a precious bounty of this intriguing substance.

Ripples on the River - Celebrating the Return of the Otter (Hardcover): Laurie Campbell, Anna Levin Ripples on the River - Celebrating the Return of the Otter (Hardcover)
Laurie Campbell, Anna Levin
R557 Discovery Miles 5 570 Ships in 10 - 15 working days

A photographic celebration of the return of otters to our rivers and freshwater wetlands after a drastic decline. Ripples of excitement are spreading through Europe's rivers and wetlands. A generation ago, otter watching was a wildlife highlight restricted to remote coastal areas - otter populations had been decimated over the previous century by pesticide poisoning and habitat disturbance. Now we are seeing the positive effect of determined conservation efforts over recent decades. As our waterways improve, otters are returning and spreading throughout their former habitats. One of the UK's leading natural history photographers, Laurie Campbell got to know otters while working in Scotland's Highlands and Islands, but he had never seen these elusive predators on his home beat. Then, in the early 1990s, he was delighted to find otters back on the Tweed and its tributaries, a river system he has lived close to for most of his life. The discovery launched him on a quest to create a photographic account of their lives on his home river. More than two decades later, otter numbers continue to increase, and new generations of otters have become more confident around people, sometimes appearing in broad daylight and in town centres. Laurie continues his long-standing study, still photographing the otters through the changing seasons - always with an eye on the bigger picture of the river itself and the plants and animals that share the otters' habitat. Wildlife journalist and writer Anna Levin accompanies Laurie to the riverbank and learns of his working philosophy and fieldcraft. Together they weave a wealth of information into the stories that the pictures tell. While extracts from Anna's notebooks offer a vivid glimpse of the photographer at work and the otters that enchant them both.

Marine Mammal Ecotoxicology: Impacts of Multiple Stressors on Population Health provides tactics on how to develop a comprehensive methodology for the study of existing threats to marine mammals. By presenting a conservation-biology approach and new and emerging technologies, this work helps provide crucial knowledge on the status of marine mammal populations that not only helps readers understand the ecosystem's health, but also instigate mitigation measures. This volume provides information that helps investigators unravel the relationships between exposure to environmental stressors (e.g., climate change, pollutants, marine litter, pathogens and biotoxins) and a range of endpoints in marine mammal species. The application of robust examination procedures and biochemical, immunological, and molecular techniques, combined with pathological examination and feeding ecology, has led to the development of health assessment methods at the individual and population levels in wild marine mammals.

R1,354 Discovery Miles 13 540 Ships in 10 - 15 working days

Archie Carr, one of the greatest biologists of the twentieth century, played a leading part in finding a new and critical role for natural history and systematics in a post-1950s world dominated by the glamorous science of molecular biology. With the rise of molecular biology came a growing popular awareness of species extinction. Carr championed endangered sea turtles, and his work reflects major shifts in the study of ecology and evolution. A gifted nature writer, his books on the natural history of sea turtles and their habitats in Florida, the Caribbean, and Africa entertained and educated a wide audience. Carr's conservation ethic grew from his field work as well as his friendships with the fishermen who supplied him with many of the stories he retold so engagingly. With Archie Carr as the focus, The Man Who Saved Sea Turtles explores the evolution of the naturalist tradition, biology, and conservation during the twentieth century.

R1,357 Discovery Miles 13 570 Ships in 10 - 15 working days

Whales and dolphins are icons for the conservation movement. They are the most conspicuous ambassadors for entire marine ecosystems and possibly even for the biosphere as a whole. Concurrent with our realisation of impending threats to their environment is a growing scientific understanding of the social and cognitive complexity of many of these species. This book brings together experts in the relevant diverse fields of cetacean research, to provide authoritative descriptions of our current knowledge of the complex behaviour and social organization of whales and dolphins. The authors consider this new information in the context of how different human cultures from around the world view cetaceans and their protection, including attitudes to whaling. They show how new information on issues such as cetacean intelligence, culture and the ability to suffer, warrants a significant shift in global perceptions of this group of animals and how these changes might be facilitated to improve conservation and welfare approaches.

R1,702 Discovery Miles 17 020 Ships in 10 - 15 working days

Marine mammals have long captured the attention of humans. Ancient peoples etched seals and dolphins on the walls of Paleolithic caves; today, engineers develop microprocessors to track these denizens of the deep. This groundbreaking book from highly respected marine mammal paleontologist Annalisa Berta delves into the story of the extraordinary adaptations that gave the world these amazing animals. The Rise of Marine Mammals reveals remarkable fossil record discoveries that shed light on the origins, relationships, and diversification of marine mammals. Focusing on evolution and paleobiology, Berta provides an overview of marine mammal species diversity, enhanced with gorgeous life restorations by Carl Buell, Robert Boessenecker, William Stout, and Ray Troll and extensive line drawings by graphics editor James L. Sumich. The book also considers ongoing conservation challenges, demonstrating how the fossil record of adaptation in response to past environmental shifts may illuminate the way that marine mammals respond to global climate change. This invaluable biological framework is essential for helping us understand how best to protect and conserve today's polar bears, whales, dolphins, seals, and fellow warm-blooded ocean dwellers. The Rise of Marine Mammals also describes exciting breakthroughs that rely on new techniques of study, including 3-D imaging, and molecular, finite element, and morphometric analyses, which have enhanced scientists' understanding of everything from the anatomy of fetal whales to the genes behind limb loss in cetaceans. Mammalogists, paleontologists, and marine scientists will find Berta's insights absorbing, while developmental and molecular biologists, geneticists, and ecologists exploring integrative research approaches will benefit from her fresh perspective.

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.

Interest in marine mammals has increased dramatically in the last few decades, as evidenced by the number of books, scientific papers, and conferences devoted to these animals. Nowadays, a conference on marine mammals can attract between one and two thousand scientists from around the world. This upsurge of interest has resulted in a body of knowledge which, in many cases, has identified major conservation problems facing particular species. At the same time, this knowledge and the associated activities of environmental organisations have served to introduce marine mammals to a receptive public, to the extent that they are now perceived by many as the living icons of biodiversity conservation. Much of the impetus for the current interest in marine mammal conservation comes from "Save the Whale" campaigns started in the 1960s by environmental groups around the world, in response to declining whale populations after over-exploitation by humans. This public pressure led to an international moratorium on whaling recommended in 1972 by the United Nations Conference on the Human Environment in Stockholm, Sweden, and eventually adopted by the International Whaling Commission ten years later. This moratorium largely holds sway to this day, and further protective measures have included the delimitation of extensive areas of the Indian Ocean (1979) and Southern Ocean (1994) as whale sanctuaries.

The rapid development of molecular biology and genetics has led to renewed interest in embryology, comparative embryology, and studies of the relations between ontogeny and phylogeny. In fact, genes have been identified which are involved in the formation of shapes and structures, and it is becoming apparent that their primary morphological expressions are conspicuously similar in different species. The primarily identical shapes do not become diversified until advanced individualization of embryos, and it is here that it is possible to employ the knowledge of comparative embryology, the branch of science engaged in the study of the development and differentiation of tridimensional structures in different animal groups. However, comparative embryology has been neglected during the past decades, as its development has appeared to have been completed. In our opinion, the decreased interest in comparative embryology has been caused by the fact that often the time factor was not or could not be respected. In fact, in the case of embryos of wild animals even their ontogenetic age and sometimes the duration of intrauterine development are unknown.

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.

This book brings together experts in the relevant diverse fields of cetacean research, to provide authoritative descriptions of our current knowledge of the complex behaviour and social organization of whales and dolphins. The authors consider this new information in the context of how different human cultures from around the world view cetaceans and their protection, including attitudes to whaling. They show how new information on issues such as cetacean intelligence, culture and the ability to suffer, warrants a significant shift in global perceptions of this group of animals and how these changes might be facilitated to improve conservation and welfare approaches.
