This book was released on 2012-12-06 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: The impetus for this volume comes from two sources. 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.

Book excerpt: Lounging atop a kelp bed, cradling a pup, or plucking morsels from a prickly urchin, sea otters are endearing creatures. SEA OTTERS captures them at their best, tracing their life cycle and behavior, and describing their brush with extinction. Including where to see them in the wild, this book is one of the most charming and complete on the subject. Color photos throughout.

This book was released on 2021-07-03 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sea otters and polar bears are carnivorous marine mammals that still resemble their terrestrial ancestors. Compared with Cetacea (whales and dolphins), Sirenia (dugongs and manatees), and Pinnipedia (seals, sea lions, and walrus), they are less adapted for an aquatic life and the most recently evolved among marine mammals. Sea otters are amphibious but seldom come ashore, and polar bears primarily occur on sea ice or along the shore. When at sea, both species spend most of their time swimming at the surface or making short, shallow dives when foraging or pursuing prey. Indeed, polar bears rarely pursue seals in water. Nevertheless, polar bears are powerful swimmers and will stalk seals from the water. As with many other large carnivores, they are solitary hunters. Although sea otters are gregarious and form aggregations at sea called rafts, they are primarily asocial. Except during mating, the principal interaction among sea otters occurs between a female and offspring during the six-month dependency period. In large carnivores (e.g., wolves and lions) that feed on ungulates, sociality and cooperation are favored because of the need to capture large prey and defend carcasses. Polar bears, which are the largest terrestrial carnivore, are solitary hunters of seals and are neither gregarious nor social. Males and females briefly associate during courtship and mating. During this time, males aggressively compete for females. At other times, males generally avoid each other except for aggregations of males that form while summering on land, and females with cubs avoid males, which are known for infanticide. As with sea otters, the interaction of polar bears outside of mating occurs between a female and her offspring during the 2-3 year dependency period. This interaction is critically important when altricial cubs are born in the winter den. This book provides new insight into the ethology and behavioral ecology of sea otters and polar bears. Each chapter reviews the discoveries of previous studies and integrates recent research using new techniques and technology. The authors also address historic and current anthropogenic challenges for their survival as climate change alters entire marine ecosystems.

Book excerpt: 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.
