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.

Much has been written about dolphins and whales, and excellent books exist especially on the charismatic bottlenose dolphins; and killer, humpback, and sperm whales. But detailed studies have been carried out on a handful of other species, and this book summarizes our state of knowledge of a little dolphin the southern hemisphere dusky, and compares its behavioral strategies in different environs. The editors, Bernd and Mel Wursig, began studying duskies in Patagonia Argentina in 1972. Although they have been to many parts of the Earth since then -- including work on Amazon and Yangtze river dolphins, Hawai i for the delicate lovely spinner dolphin, the Arctic for bowhead and gray whale work, and bottlenose dolphins in several milieus -- they have always returned to their first love of unraveling the social patterns and life strategies of duskies that exist in small groups in semi-enclosed bays and as herds of well over one thousand in the open ocean. This book documents the latest research, from their feeding patterns to their acrobatic skills. It is full of scientific facts, with a sense of poetry and wonder of the unknown.
- Only book fully devoted to the southern hemisphere "dusky" dolphin
- Heavily illustrated with charts, figures, tables, and all color photos
- Written by a cadre of experts intimately familiar with dolphin field work
- Written in an accurate yet accessible style for the scientist and natural historian alike"

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.

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.

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.

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.

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

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.

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.

Here, experts in different areas of the field provide an overview of the bioacoustics of whales and dolphins as well as a thorough introduction to the subject for investigators of hearing in other animals. Topics covered include the structure and function of cetacean auditory systems, the unique sound production system of odontocetes, acoustic communication, psychoacoustics, echolocation and models of sound propagation.

A multitude of direct and indirect human influences have significantly altered the environmental conditions, composition, and diversity of marine communities. However, understanding and predicting the combined impacts of single and multiple stressors is particularly challenging because observed ecological feedbacks are underpinned by a number of physiological and behavioural responses that reflect stressor type, severity, and timing. Furthermore, integration between the traditional domains of physiology and ecology tends to be fragmented and focused towards the effects of a specific stressor or set of circumstances. This novel volume summarises the latest research in the physiological and ecological responses of marine species to a comprehensive range of marine stressors, including chemical and noise pollution, ocean acidification, hypoxia, UV radiation, thermal and salinity stress before providing a perspective on future outcomes for some of the most pressing environmental issues facing society today. Stressors in the Marine Environment synthesises the combined expertise of a range of international researchers, providing a truly interdisciplinary and accessible summary of the field. It is essential reading for graduate students as well as professional researchers in environmental physiology, ecology, marine biology, conservation biology, and marine resource management. It will also be of particular relevance and use to the regulatory agencies and authorities tasked with managing the marine environment, including social scientists and environmental economists.

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.
