Available in PDF, EPUB and Kindle. Book excerpt: 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 excerpt: "Furry sea otters float through a kelp forest, munching on sea urchin snacks and dipping below the waves. All around them, the kelp forest is bursting with life-from fish and snails, to sea stars and crabs-that might not make it without the little otters. Sea Otters are vital to aquatic ecosystems, keeping the population of urchins in check so the kelp that houses so much life can flourish. Uncover the truth about this important keystone species, explore how sea otters shape entire ecosystems, and learn what's at risk if these hungry swimmers were to disappear. Approachable text and engaging images bring this timely topic to life"--

Available in PDF, EPUB and Kindle. Book excerpt: "Many of the findings in the book . . . are classics of ecology. . . . A rare and delightful insight into timely science."—Jane Lubchenco, Nature "Estes's refreshing narrative deftly weaves rigorous science with personal reflection to create an absorbing and introspective read that is equal parts memoir, ecological textbook, and motivational guidebook for young ecologists."—Science To newly minted biologist James Estes, the sea otters he was studying in the leafy kelp forests off the coast of Alaska appeared to have an unbalanced relationship with their greater environment. Gorging themselves on the sea urchins that grazed among the kelp, these small charismatic mammals seemed to give little back in return. But as Estes dug deeper, he unearthed a far more complex relationship between the otter and its underwater environment, discovering that otters play a critical role in driving positive ecosystem dynamics. While teasing out the connective threads, he began to question our assumptions about ecological relationships. These questions would ultimately inspire a lifelong quest to better understand the surprising complexity of our natural world and the unexpected ways we discover it. Serendipity tells the story of James Estes’s life as a naturalist and the concepts that have driven his interest in researching the ecological role of top-level predators. Using the relationships between sea otters, kelp, and sea urchins as a touchstone, Estes retraces his investigations of numerous other species, ecosystems, and ecological processes in an attempt to discover why ecologists can learn so many details about the systems in which they work and yet understand so little about the broader processes that influence these systems. Part memoir, part natural history, and deeply inquisitive, Serendipity will entertain and inform readers as it raises thoughtful questions about our relationship with the natural world.

Book excerpt: Audisee® eBooks with Audio combine professional narration and sentence highlighting for an engaging read aloud experience! A Robert F. Sibert Informational Honor Book A Green Earth Book Award Winner This up-close look at a fascinating scientific discovery highlights the critical role predators such as sea otters play in keeping ecosystems healthy. In Elkhorn Slough, an inlet on the California coast, seagrass grows healthy and strong in the shallow water. This healthy seagrass baffled marine biologist Brent Hughes. The scientist expected this estuary to be overrun with algae, causing the seagrass to die. Why was the seagrass thriving? As Brent investigated, signs pointed to an unexpected player helping to keep the seagrass healthy: sea otters! What do these top predators have to do with an aquatic grass at the opposite end of the food chain? Brent's amazing discovery gave scientists insight into the delicate balance of ecosystems. Follow science in action as Brent conducts the research that led to this major discovery.

Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Sea otters are a keystone species in their environment. If they were to disappear, the ripple effect on the plants and animals in the ecosystem would be profound. Kelp forests absorb carbon dioxide. Sea urchins feed on kelp and can deplete these forests if they are not kept in check. Sea otters prey on sea urchins, helping to maintain healthy kelp forests and thus, a healthy ecosystem. This dynamic text engages readers in an educational dialogue, examining the role of sea otters, the threats they face, and possible solutions to protect this fundamental species.

Available in PDF, EPUB and Kindle. Book excerpt: A science journalist's journey along the Pacific Coast from California to Alaska to track the status, health, habits, personality, and viability of sea otters--the appealing species unique to this coastline that was hunted to near extinction in the 18th and 19th centuries. These 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 during the 1700s and 1800s, 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 sealife. When otters disappear, sea urchins take over, and the kelp disappears along with all of the creatures that live in the beds. Now, thanks to their protected status, sea otters are making a comeback in California, Washington, and Alaska.

The first is scientific: by virtue of a preference for certain large benthic invertebrates as food, sea otters have interesting and significant effects on the structure and dynamics of nearshore communities in the North Pacific. The second is political: be cause of the precarious status of the sea otter population in coastal California, the U.S. Fish and Wildlife Service (USFWS) announced, in June 1984, a proposal to establish a new population of sea otters at San Nicolas Island, off southern California. The proposal is based on the premise that risks of catastrophic losses of sea otters, due to large oil spills, are greatly reduced by distributing the population among two geographically separate locations. The federal laws of the U.S. require that USFWS publish an Environmental Impact Statement (ElS) regarding the proposed translocation of sea otters to San Nicolas Island. The EIS is intended to be an assessment of likely bio logical, social, and economic effects of the proposal. In final form, the EIS has an important role in the decision of federal management authority (in this case, the Secretary of the Interior of the U.S.) to accept or reject the proposal.
