A book of evocative and atmospheric photographs taken by Dick Hawkes to create a representative record of this precious and ecologically unique habitat - before much of it is lost to the many threats it faces. Chalk streams have been described as England's "rainforest". Around 85% of the world's chalk streams are in England. They are beautiful, biologically distinct and amazingly rich in wildlife, but are under threat from man-made issues of abstraction, pollution from chemicals and effluent, development for housing, and climate change. Included in the book are images of typical habitats and species of wildlife found in chalk streams and water meadows, highlighting those that are rare or most under threat.

In collaboration with the Born Free Foundati on, Templar presents a series of true-life animal adventure stories, designed to bring some of today''s important wildlif e and conservation issues into the hearts and minds of a new generation of readers. '

Pinnipeds are marine mammals that include eared seals, true seals, and walruses. This book presents detailed reviews on the ecology and conservation of 10 pinniped species along the coasts and islands in Latin America, from Mexico to Chile and Argentina. Topics covered include their population dynamics, trophic ecology, reproduction, and behavior. In addition, the book addresses major conservation issues regarding climate change, interaction with fisheries, ecotourism, and other human activities.

The field of marine mammal science has made enormous strides in the last ten years of the 20th century, as well as attracting a large amount of interest, due no doubt to the public appeal of whales, dolphins, and seals, which are never out of media attention. The purpose of this book is to review key topics through chapters on the major disciplines from invited authorities around the world. Subjects covered include evolution and genetics, life histories, ecology, physiology, behaviour, medicine (diseases, parasitology), survey methodology, and all the main conservation issues (pollution, fisheries interactions, and sound disturbance). The book has an ecological and conservation emphasis since these are subject areas calling for the most attention in the modern world, but other areas such as evolution, physiology, and medicine are also given in-depth treatment. The book is written at the level of the undergraduate or above, although its style should appeal to anyone with a serious interest in marine mammal science.

This new edition - now with Nancy Jackson as a co-author - continues the themes of the first edition: the need to restore the biodiversity, ecosystem health, and ecosystem services provided by coastal landforms and habitats, especially in the light of climate change. The second edition reports on progress made on practices identified in the first edition, presents additional case studies, and addresses new and emerging issues. It analyzes the tradeoffs involved in restoring beaches and dunes - especially on developed coasts - the most effective approaches to use, and how stakeholders can play an active role. The concept of restoration is broad, and includes physical, ecological, economic, social, and ethical principles and ideals. The book will be valuable for coastal scientists, engineers, planners, and managers, as well as shorefront residents. It will also serve as a useful supplementary reference textbook in courses dealing with issues of coastal management and ecology.

'A must-read' New Scientist 'Fascinating' Greta Thunberg 'Enthralling' George Monbiot 'Brilliant' Philip Hoare A thrilling investigation into the pioneering world of animal communication, where big data and artificial intelligence are changing our relationship with animals forever In 2015, wildlife filmmaker Tom Mustill was whale watching when a humpback breached onto his kayak and nearly killed him. After a video clip of the event went viral, Tom found himself inundated with theories about what happened. He became obsessed with trying to find out what the whale had been thinking and sometimes wished he could just ask it. In the process of making a film about his experience, he discovered that might not be such a crazy idea. This is a story about the pioneers in a new age of discovery, whose cutting-edge developments in natural science and technology are taking us to the brink of decoding animal communication - and whales, with their giant mammalian brains and sophisticated vocalisations, offer one of the most realistic opportunities for us to do so. Using 'underwater ears,' robotic fish, big data and machine intelligence, leading scientists and tech-entrepreneurs across the world are working to turn the fantasy of Dr Dolittle into a reality, upending much of what we know about these mysterious creatures. But what would it mean if we were to make contact? And with climate change threatening ever more species with extinction, would doing so alter our approach to the natural world? Enormously original and hugely entertaining, How to Speak Whale is an unforgettable look at how close we truly are to communicating with another species - and how doing so might change our world beyond recognition.

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.

How intelligent are dolphins? Is their communication system really as complex as human language? And are they as friendly and peaceful as they are made out to be? The Western world has had an enduring love affair with dolphins since the early 1960s, with fanciful claims of their 'healing powers' and 'super intelligence'. Myths and pseudoscience abound on the subject. Justin Gregg weighs up the claims made about dolphin intelligence and separates scientific fact from fiction. He puts our knowledge about dolphin behaviour and intelligence into perspective, with comparisons to scientific studies of other animals, especially the crow family and great apes. He gives fascinating accounts of the challenges of testing what an animal with flippers and no facial expressions might be animal behaviour, Gregg challenges many of the widespread beliefs about dolphins, while also inspiring the reader with the remarkable abilities common to many of the less glamorized animals around us - such as chickens.

Research in whale origins is now in an explosive phase, with a cascade of discoveries adding to our understanding of the evolutionary pattern and a suite of new techniques being applied to address new questions. 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.

This book is a collection of original research papers given at a symposium entitled "Sensory Systems and Behavior of Aquatic Mammals", hosted by the USSR Academy of Sciences. The meeting was held in Moscow from 16 to 25 October, 1991 and involved nearly 100 scientists from around the world. The major headings of the book correspond to the session topics at the symposium. This meeting was not the first dedicated to problems of sensory systems in aquatic mammals. Experts in this field met several times previously to discuss important problems of sensory functions in echolocating animals. symposia on biosonar systems were held in Frascati, Italy in 1966, then in Jersey, France in 1978, and in Helsingor, Denmark in 1986. Papers presented at these meetings were pUblished in books that advanced significantly the understanding of sensory systems (Busnel and Fish, 1980; Nachtigall and Moore, 1988). Initially, echolocating bats were the main subjects of consideration. However, studies on echolocating aquatic mammals, whales and dolphins, increased from one meeting to the next. Indeed, aquatic mammals are of exceptional interest for studying the adaptation of sensory functions for echolocation in specific aquatic environments. As a natural consequence of these developments, the 1989 symposium in Rome was devoted specifically to the sensory systems of cetaceans (Thomas and Kastelein, 1990). This symposium was held within the Fifth International Theriological Congress and was attended by many scientists.

The seventh volume in the series "Ethology and Behavioral Ecology of Marine Mammals" describes aspects of the often-complex relationship between humans and marine mammals. From a primeval condition of occasional predators, during the last century humans have become a major factor negatively affecting the status of most marine mammals through over-hunting, habitat encroachment and environmental degradation. This has led to the extirpation of many marine mammal populations and even to the extinction of species. However, in parallel to this destructive drive, since antiquity humanity has been influenced by a strong fascination for marine mammals, which contributes today to an increased human appreciation of the natural world admixed with widespread concern for its degrading condition. The special status occupied by marine mammals in human imagination and affection stands in stark contrast with the current predicament of many populations still threatened by the doings of Homo sapiens: a condition emblematic of the relationship of humanity with nature, and key to understanding where humanity is heading.

The extraordinary ability of dolphins to echolocate has fascinated scientists and the public since its discovery in the late 1950's. This is the first book to summarize modern research in this area, and presents a broad synthesis of this very interdisciplinary subject. The author is an internationally-recognized expert on dolphin sonar and is thus in a unique position to bring together research on the physiological, mathematical and engineering aspects of the subject. Of interest to auditory researchers, electrical engineers, acoustical physicists, and mammalian physiologists.

How do whales experience environmental change? Has our connection to these animals been transformed by technology? What future awaits us, and them? Fathoms blends natural history, philosophy, and science to explore these questions. Giggs introduces us to whales so rare they have never been named and tells us of whale 'pop' songs that sweep across hemispheres. She takes us into the deeps to discover that one whale's death can spark a great flourishing of creatures. We travel to Japan to board whaling ships, examine the uncanny charisma of these magnificent mammals, and confront the plastic pollution now pervading their underwater environment.

Marine mammals include some of the most fascinating animals on Earth. Large, majestic whales and stunning, playful dolphins have provided mysterious companionship to humans at sea for hundreds of years.

The activities of modern society have unleashed a range of toxic chemicals into the global environment. Many of these toxicants are now being detected in increasing quantities in the tissues of marine mammals, most notably in top predators who acquire relatively large amounts of toxic chemicals by ingesting contaminated prey. Toxicology of Marine Mammals focuses on the effects of natural and introduced toxicants on organs and systems in marine mammals. It provides overviews on health status and contamination, with subsequent chapters devoted to whales, pinnipeds, dolphins, polar bears, manatees, and sea otters. Internationally renowned researchers assess the mounting evidence for adverse effects on reproduction and the chemically-induced increased susceptibility to death from infectious diseases. The concluding chapter addresses perspectives and issues for the future. This compelling book features research from a vast geographic landscape ranging from the tropics to the Arctic, with case studies on intriguing areas of contamination such as the St. Lawrence River and the Baltic Sea. It identifies the severe threats that environmental contaminants pose to the health and future of marine mammals. It also makes an urgent call for legislation to regulate the incessant pollution ravaging our seas and devastating the marine mammal population worldwide. Toxicologists working in marine biology and veterinary medicine, conservation scientists, fisheries scientists, environmental scientists, and wildlife managers will all benefit from this comprehensive resource.

There are fewer grey seals in the world than endangered African elephants, but the British Isles host almost half of this global population. Every year these charismatic animals, with their expressive eyes and whiskers more sensitive than our fingertips, haul out on our shores to breed and raise their pups. Susan Richardson has always been entranced by seals; they seem to have surfaced at key junctions throughout her life, comforting her as an anxious child, bringing joy as she began to spread her wings as a writer and helping her to find her way after the loss of her mother. Now she sets out to trace the rhythm of their lives, travelling the coasts clockwise from Cornwall to Norfolk, in line with the autumn pupping season. Along the way she explores the myths surrounding seals, from their shapeshifting selkie skins to the claims that they decimate fish populations, and she discovers that the greatest dangers they face come from co-existing with us. Brimming with vivid descriptions of the natural world, Where the Seals Sing is a lyrical tale of memory, rescue and rehabilitation. While loss, both personal and ecological, is a recurring theme, the human-seal connection that flows through the story is stirring and uplifting.

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.

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.
