Abstract

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 population

Abstract

";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.

Abstract

For more than ten thousand years, Native Americans from Alaska to southern California relied on aquatic animals such as seals, sea lions, and sea otters for food and raw materials. Archaeological research on the interactions between people and these marine mammals has made great advances recently and provides a unique lens for understanding the human and ecological past. Archaeological research is also emerging as a crucial source of information on contemporary environmental issues as we improve our understanding of the ancient abundance, ecology, and natural history of these species. This groundbreaking interdisciplinary volume brings together archaeologists, biologists, and other scientists to consider how archaeology can inform the conservation and management of pinnipeds and other marine mammals along the Pacific Coast.

Abstract

From gray whales giving birth in the lagoons of Baja California to sea otters nestled in kelp beds off California to killer whales living around Vancouver Island-this spectacular stretch of the Pacific Coast boasts one of the most abundant populations of sea mammals on earth. This handy interpretive field guide describes the 45 whales, dolphins, seals, and otters that are resident in, migrate through, or forage from Baja in Mexico to British Columbia in Canada. The guide's rich species accounts provide details on identification, natural history, distribution, and conservation. They also tell where and how these fascinating animals can best be viewed. Introductory chapters give general information on the ecology, evolution, and taxonomy of marine mammals; on the Pacific Coast's unique environment; and on the relationship between marine mammals and humans from native cultures to today. Featuring many color illustrations, photographs, drawings, and maps, this up-to-date guide illuminates a fascinating group of animals and reveals much about their mysterious lives in the ocean.
