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.

Download or read book If You Take Away the Otter written by Susannah Buhrman-Deever and published by Candlewick. This book was released on 2020-05-26 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: When the sea otters disappear, why does their kelp forest habitat disappear, too? On the Pacific Coast of North America, sea otters play, dive, and hunt for sea urchins, crabs, abalone, and fish in the lush kelp forests beneath the waves. But there was a time when people hunted the otters almost to extinction. Without sea otters to eat them, an army of hungry sea urchins grew and destroyed entire kelp forests. Fish and other animals that depended on the kelp were lost, too. But when people protected the sea otters with new laws, their numbers began to recover, and so did the kelp forests. Susannah Buhrman-Deever offers a beautifully written account of a trophic cascade, which happens when the removal of a single element affects an entire habitat. Asides that dig deeper are woven throughout Matthew Trueman’s dynamic illustrations, starring a raft of charismatic sea otters. Back matter includes more information about sea otters and kelp forests, including their importance and current status, the effects of the international fur trade on indigenous peoples, and a list of books and websites for readers who wish to continue to explore.

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 Edible Sea Urchins Biology and Ecology written by John M. Lawrence and published by Elsevier. This book was released on 2001-05-21 with total page 429 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sea urchins are a major component of marine environments found throughout the world's oceans. A major model for research in developmental biology, they are also of major economic importance in many regions and interest in their management and aquaculture has increased greatly in recent years. This book provides a synthesis of biological and ecological characteristics of sea urchins that are of basic scientific interest and also essential for effective fisheries management and aquaculture. General chapters consider characteristics of sea urchins as a whole. In addition, specific chapters are devoted to the ecology of 17 species that are of major commercial interest and ecological importance. Features include: • A synthesis of what is known about the basic biological characteristics of the sea urchin, useful for the direction of future research. • Case histories of 17 species that illustrate their ecological role in a variety of environments. • With the catastrophic decline in fisheries resulting primarily from over-fishing, it is essential that the populations be managed effectively and that aquaculture be developed. This book provides knowledge of the biology and ecology of the commercially important sea urchins that will contribute to these goals. • The only book available in present literature devoted to sea urchins. With this new title experts provide a broad synthetic treatment and in depth analysis of the biology and ecology of sea urchins from around the world, designed to provide an understanding of the group and the basis for fisheries management and aquaculture.

Available in PDF, EPUB and Kindle. Book excerpt: 'Wise, challenging and offering some unexpected laughter in the dark, this is a rational and insightful account of the sixth great extinction event. Peter Marren is a brilliant writer and a national treasure.' PATRICK BARKHAM 'Thoughtful, fascinating and very timely.' STEPHEN MOSS 'Important and thought-provoking.' CAROLINE LUCAS, GREEN PARTY MP 'Essential reading. Marren makes a page-turner out of Armageddon.' SIMON BARNES 'In his characteristic style Peter Marren has humanised the story of wildlife losses with humour and wit but also with his enormous knowledge and deep love for the living world.' MARK COCKER We are in the midst of an extinction event: the sixth mass extinction on earth and one entirely caused by mankind. All species become extinct sooner or later, but we have accelerated that natural process several hundredfold and now, it is happening right in front of our eyes. Extinction has a terrifying finality to it. And many species have already been lost to us forever; there is little we can do about that. What we can do, however, is reflect, remember, and ultimately acknowledge the unvarnished truth. We must see the natural world as it is, and not as we might want it to be. Our trajectory is one that has benefited one species alone - humankind. For all other beings, from mammals to fish, from birds to insects and coral, from plants to lichens and fungi, the future, for better or worse, is in our hands.

Available in PDF, EPUB and Kindle. Book excerpt: Over the last two decades, the scientific and popular media have been bombarded by gloom and doom stories of the future of fisheries, the status of fish stocks, and the impact of fishing on marine ecosystems. Dozens of certification and labeling schemes have emerged to advise consumers on what seafood is sustainable. In recent years, an opposing narrative has emerged emphasizing the success of fisheries management in many places, the increasing abundance of fish stocks in those places, and the prescription for sustainable fisheries. However, there has been no comprehensive survey of what really constitutes sustainability in fisheries, fish stock status, success and failures of management, and consideration of the impacts of fishing on marine ecosystems. This book will explore very different perspectives on sustainability, and bring together the data from a large number of studies to show where fish stocks are increasing, where they are declining, the consequences of alternative fisheries management regimes, and what is known about a range of fisheries issues such as the impacts of trawling on marine ecosystems. Ocean Recovery is aimed principally at a general audience that is already interested in fisheries but seeks both a deeper understanding of what is known about specific issues and an impartial presentation of all the data rather than selected examples used to justify a particular perspective or agenda. It will also appeal to the scientific community eager to know more about marine fisheries and fishing data, and serve as the basis for graduate seminars on the sustainability of natural resources.

Book excerpt: “Blue Monday leaves readers with the promise of intriguing tales to come” —People (four-star review) Internationally bestselling authors Nicci Gerard and Sean French, writing as Nicci French, have sold more than eight million copies of their books worldwide. But nothing they’ve written written before has grabbed the attention of reviewers and readers like Blue Monday and its iconic heroine, Frieda Klein. In a starred review, Publishers Weekly called it a “superb psychological thriller . . . with brooding atmosphere, sustained suspense, a last-minute plot twist, and memorable cast of characters.” In Tuesday’s Gone, a London social worker makes a routine home visit only to discover her client, Michelle Doyce, serving afternoon tea to a naked, decomposing corpse. With no clues as to the dead man’s identity, Chief Inspector Karlsson again calls upon Frieda for help. She discovers that the body belongs to Robert Poole, con man extraordinaire. But Frieda can’t shake the feeling that the past isn’t done with her yet. Did someone kill Poole to embroil her in the investigation? And if so, is Frieda herself the next victim? A masterpiece of paranoia, Tuesday’s Gone draws readers inexorably into a fractured and faithless world as it brilliantly confirms Frieda Klein as a quintessential heroine for our times.

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.
