This book fully documents the natural history of Sirenia, the order of aquatic mammals including manatees of the Caribbean, West Africa, and the Amazon, as well as the Indo-Pacific dugong.

"An excellent introduction to the natural history of the four living species of sirenian, including the Florida and Antillean sub-species of the West Indian manatee, the Amazonian manatee, and the dugong, as well as the extinct Stellar's Sea Cow."--Jacket

A synthesis of the ecological and related knowledge pertinent to understanding the biology and conservation of dugongs and manatees.

This important scientific volume comprehensively explores the biology and ecological status of manatees and dugongs in all of the geographic regions where they can be found today, from the Caribbean to Eastern Africa, from Arabia to the Amazon, and from Japan through the South Pacific to Australia. Many of these dwindling populations are situated in developing countries--locales that have previously received little attention in the scientific literature. In these areas, people occupying rivers or coastlines still capture sirenians for food and other uses (oil, bones for carving, leather). In addition, disruption, erosion, or complete loss of sirenian habitat occurs because of dredge and fill, coastal run-off, chemical pollution, and damage from boat propellers. Sirenian Conservation features contributions from an international group of scientists who are working to address the many challenges to manatee and dugong food supply, environment, reproduction, and survival. They share stories of programs that rescue, rehabilitate, release, and monitor these animals; offer reports on practical, replicable, and cost-effective management techniques; and summarize current research strategies.

Marine mammals attract human interest – sometimes this interest is benign or positive – whale watching, conservation programmes for whales, seals, otters, and efforts to clear beaches of marine debris are seen as proactive steps to support these animals. However, there are many forces operating to affect adversely the lives of whales, seals, manatees, otters and polar bears – and this book explores how the welfare of marine mammals has been affected and how they have adapted, moved, responded and sometimes suffered as a result of the changing marine and human world around them. Marine mammal welfare addresses the welfare effects of marine debris, of human traffic in the oceans, of noise, of hunting, of whale watching and tourism, and of some of the less obvious impacts on marine mammals – on their social structures, on their behaviours and migration, and also of the effects on captivity for animals kept in zoos and aquaria. There is much to think and talk about – how marine mammals respond in a world dramatically influenced by man, how are their social structures affected and how is their welfare impacted?

A photographic journey into the secret world of Florida’s beloved manatee. Winner of the CHOICE Outstanding Academic Title of the Choice ACRL 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

The dugong (Dugong dugon) is the only herbivorous mammal that is strictly marine. It has a range spanning some 37 countries, including tropical and subtropical coastal and island waters. This plan presents a global overview of the status of the dugong and its management throughout its range. It contains information on dugong distribution and abundance, threatening processes, legislation, and existing and suggested research and management initiatives for the countries and territories in the dugong’s known range. It is hoped that the comparative information provided will enable individual countries to develop their own, more detailed, conservation plans.

This comprehensive book provides new insights into the morphological, metabolic, thermoregulatory, locomotory, diving, sensory, feeding, and sleep adaptations of Cetacea (whales and dolphins), Pinnipedia (seals, sea lions and walrus), Sirenia (manatees and dugongs) and sea otters for an aquatic life. Each chapter reviews the discoveries from previous studies and integrates recent research using new techniques and technology. Readers will gain an understanding of the remarkable adaptations that enable marine mammals to spend all or most of their lives at sea, often while hunting prey at depth.

Berta and Sumich have succeeded yet again in creating superior marine reading! This book is a succinct yet comprehensive text devoted to the systematics, evolution, morphology, ecology, physiology, and behavior of marine mammals. The first edition, considered the leading text in the field, is required reading for all marine biologists concerned with marine mammals. Revisions include updates of citations, expansion of nearly every chapter and full color photographs. This title continues the tradition by fully expanding and updating nearly all chapters. - Comprehensive, up-to-date coverage of the biology of all marine mammals - Provides a phylogenetic framework that integrates phylogeny with behavior and ecology - Features chapter summaries, further readings, an appendix, glossary and an extensive bibliography - Exciting new color photographs and additional distribution maps

Describes the physical characteristics, habitat, and behavior of manatees and dugongs--endangered, vegetarian mammals that live in the water.
