Download or read book Keystone Species That Live in the Sea and Along the Coastline written by Bonnie Hinman and published by Mitchell Lane Publishers, Inc.. This book was released on 2015-09 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most arches built today contain a single building block at the top that is the most important piece. This special piece can be found in the arches of soaring cathedrals, doorways in temples, and even simple buildings made out of wooden blocks. It is called a keystone, and it holds everything else together. Remove the keystone and the building or doorway is likely to collapse.The same thing is true in nature. Certain species of animals and plants are so important to their ecosystems, that if they disappear, the whole system may collapse. They are called keystone species.Some keystone species are large, like white rhinos, while others are quite small, like honey bees. But size doesn't matter in an ecosystem. All living things rely on other species to survive. A keystone species plays an especially large role that affects many different species in an ecosystem. Some keystone species are at the top of a huge ecosystem like the Greater Yellowstone Ecosystem, while others may affect a tiny ecosystem in a river or forest. Whether the ecosystem is big or small, the result of a keystone species disappearing or being greatly reduced is the same. Just like one falling domino can cause many others to fall, the loss of a keystone species can lead to the extinction of many other species.Today scientists are focusing more attention on preserving the natural balance in ecosystems. Identifying and protecting keystone species is an important part of their work.

Available in PDF, EPUB and Kindle. Book excerpt: "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.
Download or read book Sea Otter Conservation written by Shawn Larson and published by Academic Press. This book was released on 2014-12-23 with total page 468 pages. 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
Download or read book The Community Ecology of Sea Otters written by Glenn R. VanBlaricom and published by Springer Science & Business Media. 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.

Available in PDF, EPUB and Kindle. Book excerpt: "Ocean Bestiary tells the history of our relationship with the sea, one animal at a time, from A to Z. From the earliest Polynesian navigators to the pilots of deep-sea submersibles today, humans have been exploring the globe's most dominant and inaccessible ecosystem and bringing home to those ashore breathtaking accounts of what they observed. Jumping off from the stories of whalemen, pirates, explorers, immigrants, naturalists, writers, painters, and cruiser-sailors-some famous, some entirely unknown and unpublished-this little book examines and shares what it was they saw. Ocean Bestiary crosses a range of geographies and oceanic environments, from shallows to depths and including coral reefs, upwelling zones, and more. It covers an equally wide range of organisms as well, from tiny zooplankton to immense whales. In playful prose, Richard J. King unfurls his stories and their relevance today for our understanding of environmental history, the history of marine biology, and our shifting perceptions of the ocean"--

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: 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.

Download or read book The Physics of Evolution written by Michael W. Roth and published by CRC Press. This book was released on 2023-06-06 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an introduction to the significant role of physics in evolution, based on the ideas of matter and energy resource flow, organism self-copying, and ecological change. The text employs these ideas to create quantitative models for important evolutionary processes. Many fields of science and engineering have come up against the problem of complex design—when details become so numerous that computer power alone cannot make progress. Nature solved the complex-design problem using evolution, yet how it did so has been a mystery. Both laboratory experiments and computer-simulation attempts eventually stopped evolving. Something more than Darwin’s ideas of heredity, variation, and selection was needed. The solution is that there is a fourth element to evolution: ecological change. When a new variation is selected, this can change the ecology, and the new ecology can create new opportunities for even more new variations to be selected. Through this endless cycle, complexity can grow automatically. This book uses the physics of resource flow to describe this process in detail, developing quantitative models for many evolutionary processes, including selection, multicellularity, coevolution, sexual reproduction, and the Serengeti Rules. The text demonstrates that these models are in conceptual agreement with numerous examples of biological phenomena, and reveals, through physics, how complex design can arise naturally. This will serve as a key text on the part physics plays in evolution, and will be of great interest to students at the university level and above studying biophysics, physics, systems biology, and related fields.
Download or read book Sea Change written by Ussif Rashid Sumaila and published by UBC Press. This book was released on 2024-04-01 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: As climate change, resource overexploitation, and pollution leave ever more visible marks, ocean ecosystems, economies, and people are all affected. With coasts on the Atlantic, Pacific, and Arctic, Canada faces a formidable challenge in building resilient, sustainable oceans and supporting the communities that rely on them. Sea Change reports on the OceanCanada Partnership, a multidisciplinary project to take stock of what we know about Canada’s oceans, construct possible scenarios for coastal regions, and create a national dialogue and vision. Three themes emerge from this impressive synthesis of social, cultural, economic, and environmental research: ocean change, access to ocean resources, and ocean governance. Indigenous and non-Indigenous scholars and practitioners focus on finding solutions to rapid environmental and social transformation, outlining the implications for legislation and offering policy recommendations. Increasingly, civil society will have to advocate for oceans, and Sea Change will empower the voices of those who take up that task.
Download or read book Sustainability and the Rights of Nature in Practice written by Cameron La Follette and published by CRC Press. This book was released on 2019-09-30 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainability and the Rights of Nature in Practice is the much-needed complementary volume to Sustainability and the Rights of Nature: An Introduction (CRC Press, May 2017). The first book laid out the international precursors for the Rights of Nature doctrine and described the changes required to create a Rights of Nature framework that supports Nature in a sustainable relationship rather than as an exploited resource. This follow-up work provides practitioners from diverse cultures around the world an opportunity to describe their own projects, successes, and challenges in moving toward a legal personhood for Nature. It includes contributions from Nepal, New Zealand, Canadian Native American cultures, Kiribati, the United States and Scotland, amongst others, by practitioners working on projects that can be integrated into a Rights of Nature framework. The authors also tackle required changes to shift the paradigm, such as thinking of Nature in a sacred manner, reorienting Nature’s rights and human rights, the conceptualization of restoration, and the removal of large-scale energy infrastructure. Curated by experts in the field, this expansive collection of papers will prove invaluable to a wide array of policymakers and administrators, environmental advocates and conservation groups, tribal land managers, and communities seeking to create or maintain a sustainable relationship with Nature. Features: Addresses existing projects that are successfully implementing a Rights of Nature legal framework, including the difference it makes in practice Presents the voices of practitioners not often recognized who are working in innovative ways towards sustainability and the need to grant a voice to Nature in human decision-making Explores new ideas from the insights of a diverse range of cultures on how to grant legal personhood to Nature, restrain damaging human activity, create true sustainability, and glimpse how a Rights of Nature paradigm can work in different societies Details the potential pitfalls to Rights of Nature governance and land use decisions from people doing the work, as well as their solutions Discusses the basic human needs for shelter, food, and community in entirely new ways: in relationship with Nature, rather than in conquest of it
