Book Description
Sea otters are good indicators of ocean health. In addition, they are a keystone species, offering a stabilizing effect on ecosystem, controlling sea urchin populations that would otherwise inflict damage to kelp forest ecosystems. The kelp forest ecosystem is crucial for marine organisms and contains coastal erosion. With the concerns about the imperiled status of sea otter populations in California, Aleutian Archipelago and coastal areas of Russia and Japan, the last several years have shown growth of interest culturally and politically in the status and preservation of sea otter populations. Sea Otter Conservation brings together the vast knowledge of well-respected leaders in the field, offering insight into the more than 100 years of conservation and research that have resulted in recovery from near extinction. This publication assesses the issues influencing prospects for continued conservation and recovery of the sea otter populations and provides insight into how to handle future global changes. - Covers scientific, cultural, economic and political components of sea otter conservation - Provides guidance on how to manage threats to the sea otter populations in the face of future global changes - Highlights the effects that interactions of coastal animals have with the marine ecosystem

Book Description
Sea otters once ruled the Pacific Ocean, but the fur trade of the eighteenth and nineteenth centuries brought this predator to near extinction. Today they’re slowly coming back from the brink, and scientists are learning more about their pivotal role as one of nature’s keystone species. This book looks at the history, biology, behavior and uncertain future of sea otters. Author and photojournalist Isabelle Groc takes us into the field: watching sea otter rafts off the British Columbia coast from a kayak, exploring what makes their fur coats so special, understanding how their voracious appetites are helping kelp forests thrive and, ultimately, learning how sea otters are leaving their mark (or paws) on every part of the ecosystem. They might be one of the most adorable creatures in the ocean, but kids will discover how their survival is key to a rich, complex and connected ecosystem.

Book Description
This book focuses on the European otter, describing its life history, including fresh information and providing details of survey methods and the state of populations throughout the range. Otters have decreased substantially in numbers and range during the present century through a combination of pollution, habitat destruction and direct persecution. The otter, at the top of the food chain, is a vulnerable animal in a vulnerable environment - the river - and can be seen as an indicator of a healthy environment; a good otter population indicates a properly functioning river ecosystem. The research of the authors highlights the fact that successful conservation of this familiar though elusive animal depends upon public education and sympathy as much as upon detailed ecological knowledge. This account will appeal to amateur naturalists, teachers of natural history and biological sciences and students of animal ecology and conservation. It also provides an important reference for professional conservationists and wildlife biologists.

Book Description
Although rarely seen in the wild, the otter is admired for its playful character and graceful aquatic agility, fixed in the popular imagination through books and films such as Tarka the Otter and Ring of Bright Water. This is just a small part of its story, however: throughout history, the otter has been hunted for its fur and to prevent it from killing fish. Featuring numerous images from nature and culture, as well as examples from folklore, sports, and literature, this wide-ranging book also explores the movement against otter hunting, and the ongoing efforts promoting otter conservation. A fittingly lively study of its subject, Otter offers a new way of thinking about this much-loved but endangered animal.

Book Description
"Captivating. . . . a full portrait of this adorable and ecologically important animal." —Publishers Weekly A science journalist travels the Pacific Coast in search of sea otters in this entertaining and inspiring book on the importance and history of this charismatic endangered species Sea otters—the adorable, furry marine mammals often seen floating on their backs holding hands—reveal the health of the coastal ecosystem along the Pacific Ocean. Once hunted for their prized fur in the 18th and 19th centuries, these animals nearly went extinct. Only now, nearly a century after hunting ceased, are populations showing stable growth in some places. Sea otters are a keystone species in coastal areas, feeding on sea urchins, clams, crab, and other crustaceans. When they are present, kelp beds are thick and healthy, providing homes for an array of sea life. When otters disappear, sea urchins take over, and the kelp disappears along with all the creatures that live in the beds. Now, thanks to their protected status, sea otters are making a comeback in California, Washington, and Alaska. In this hopeful book, science writer Todd McLeish embarks on an epic journey along the Pacific Coast—traveling from California to Alaska—to track the status, health, habits, personality, and viability of sea otters, and reveals how conservationists brought them back from the brink of extinction.

Book Description
“The bones recovered from the middens of the northeastern Pacific shorelines have important stories to tell biologists, marine mammalogists, and those concerned with marine conservation. This volume unearths a wealth of information about the historical ecology of seals, sea lions, and sea otters in the North Pacific that spans thousands of years. It provides fascinating insights into how the world once looked, and how it may one day look again as seals, sea lions, and sea otters reclaim and recolonize their former haunts.”—Andrew Trites, Director, Marine Mammal Research Unit, University of British Columbia “Braje and Rick have assembled a compelling set of case studies on the long-term and complex interactions between people, marine mammals, and environments in the Northeast Pacific. The promise of zooarchaeology as historical science is on full display, as researchers use geochemistry, aDNA, morphometrics, and traditional analytic methods to address questions of utmost importance to the long-term health of coastal ecosystems. If this book doesn't convince conservation biology about the need to take the long view of animal histories and ecosystems into account in developing conservation management plans, I'm not sure what will.”—Virginia L.

"Calling all sea otter fans!" - Kirkus On a sunny August morning in 2016, a baby sea otter was found washed up on the sand. Orphaned and sick, Rialto was taken to the Seattle Aquarium, where his dedicated caretakers nursed him back to health and taught him how to be an otter. Soon, the charming Rialto was stealing hearts as he played with toys made of ide, swam in his very own pool, ate tasty clams, and floated on his back. Learn about the rescue--and how you can help to save this endangered species--in Rescuing Rialto, from the Seattle Times reporter and photographer who chronicled this story as it happened. Just as he captured them, Rialto's sure to steal your heart, too.
