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

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.

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.

2019 Choice Outstanding Academic Title More than any other nonhuman species, it was the sea otter that defined the world's largest oceanscape prior to the California gold rush. In addition to the more conventional aspects of the sea otter trade, including Russian expansion in Alaska, British and American trading in the Pacific Northwest, and Spanish colonial ventures along the California coast, the global importance of the species can be seen in its impact on the East Asian maritime fur trade. This trade linked Imperial China, Japan, and indigenous Ainu peoples of the Kurile Islands as early as the fifteenth century. In Sea Otters: A History Richard Ravalli synthesizes anew the sea otter's complex history of interaction with humans by drawing on new histories of the species that consider international and global factors beyond the fur trade, including sea mammal conservation, Cold War nuclear testing, and environmental tourism. Examining sea otters in a Pacific World context, Ravalli weaves together the story of imperial ambition, greed, and an iconic sea mammal that left a determinative imprint on the modern world.

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.
