Available in PDF, EPUB and Kindle. Book excerpt: Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.

Available in PDF, EPUB and Kindle. Book excerpt: Series Editor: Peter Calow, Department of Zoology, University of Sheffield, England The main aim of this series will be to illustrate and to explain the way organisms 'make a living' in nature. At the heart of this - their functional biology - is the way organisms acquire and then make use of resources in metabolism, movement, growth, reproduction, and so on. These processes will form the fundamental framework of all the books in the series. Each book will concentrate on a particular taxon (species, family, class or even phylum) and will bring together information on the form, physiology, ecology and evolutionary biology of the group. The aim will be not only to describe how organisms work, but also to consider why they have come to work in that way. By concentration on taxa which are well known, it is hoped that the series will not only illustrate the success of selection, but also show the constraints imposed upon it by the physiological, morphological and developmental limitations of the groups. Another important feature of the series will be its organismic orientation. Each book will emphasize the importance of functional integration in the day to-day lives and the evolution of organisms. This is crucial since, though it may be true that organisms can be considered as collections of gene determined traits, they nevertheless interact with their environment as integrated wholes and it is in this context that individual traits have been subjected to natural selection and have evolved.

Download or read book After the Earth Quakes written by Susan Elizabeth Hough and published by Oxford University Press. This book was released on 2005-11-24 with total page 467 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earthquakes rank among the most terrifying natural disasters faced by mankind. Out of a clear blue sky-or worse, a jet black one-comes shaking strong enough to hurl furniture across the room, human bodies out of bed, and entire houses off of their foundations. When the dust settles, the immediate aftermath of an earthquake in an urbanized society can be profound. Phone and water supplies can be disrupted for days, fires erupt, and even a small number of overpass collapses can snarl traffic for months. However, when one examines the collective responses of developed societies to major earthquake disasters in recent historic times, a somewhat surprising theme emerges: not only determination, but resilience; not only resilience, but acceptance; not only acceptance, but astonishingly, humor. Elastic rebound is one of the most basic tenets of modern earthquake science, the term that scientists use to describe the build-up and release of energy along faults. It is also the best metaphor for societal responses to major earthquakes in recent historic times. After The Earth Quakes focuses on this theme, using a number of pivotal and intriguing historic earthquakes as illustration. The book concludes with a consideration of projected future losses on an increasingly urbanized planet, including the near-certainty that a future earthquake will someday claim over a million lives. This grim prediction impels us to take steps to mitigate earthquake risk, the innately human capacity for rebound notwithstanding.

Download or read book Four Months in a Sneak Box written by Nathaniel H. Bishop and published by Good Press. This book was released on 2019-11-27 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Four Months in a Sneak-Box" is the travel memoir of adventurer Nathaniel H. Bishop, about a boat voyage he undertook down the Ohio and Mississippi rivers, and along the gulf of Mexico. He had procured the smallest and most comfortable of boats—a purely American model, developed by the bay-men of the New Jersey coast of the United States, and recently introduced to the gunning fraternity as the 'Barnegat Sneak-Box'. This curious and stanch little craft, though only twelve feet in length, proved a most comfortable and serviceable home while the author rowed in it more than 2600 miles down the Ohio and Mississippi rivers, and along the coast of the Gulf of Mexico, until he reached the goal of his voyage—the mouth of the wild Suwanee River.

Available in PDF, EPUB and Kindle. Book excerpt: "The Freshwater Mussels of Tennessee . . . is indispensable to anyone, anywhere, working on this group. Parmalee and Bogan have written a work that sets the standard for future regional guides."--G. Thomas Watters, Ohio Biological Survey "The Freshwater Mussels of Tennessee documents a tremendously diverse and unique mussel fauna that is rapidly being destroyed by modern development. Parmalee and Bogan set a new standard for state mussel surveys in their authoritative, thorough, and and highly readable account. The book will be of interest to biologists and conservationists worldwide and will appeal to anyone who cares about the preservation of natural resources in the southeastern United States."--Robert E. Warren, Illinois State Museum With more than 150 species and subspecies recorded in the state, Tennessee has one of the most diverse freshwater mussel faunas in North America. Valuable as indicators of water quality, these mollusks have themselves become threatened as development encroaches on habitat--twenty-three are currently listed as endangered species and at least twelve have become extinct. This is the first book for Tennessee to deal with this biologically and commercially significant group of mollusks. Its authors have been studying and writing about the mussels of Tennessee for more than twenty years and have undertaken a systematic organization of a large and complex body of information to bring order to a difficult field. The book traces the long history of human exploitation of mussels, from aboriginal food gathering to the growth of the cultured pearl industry. It provides an interpretive context for its exhaustive species accounts with background material on biology, distribution, economic utilization, taxonomy, and conservation issues. The authors also review the life cycle of the mussel and describe its many remarkable traits, such as its shell formation and the strategies it employs during the larval stage in parasitizing fish. The species accounts comprise 128 members of Family Unionidae--from pigtoes and pocketbooks to lilliputs and spikes--plus four additional species. The authors cover classification and synonymy, range and distribution, life history and ecology, and survival status. Particular attention is paid to shell description and structure to assist the reader in identification. Each species account includes a distribution map and color photos of two specimens. The Freshwater Mussels of Tennessee is a major reference that encompasses historical and modern mussel collections and draws on conservation studies that span two centuries. It will stand as an authoritative guide to understanding Tennessee mollusks and as a benchmark in the study of these species worldwide. The Authors: Paul W. Parmalee is professor emeritus of zooarchaeology and director emeritus of the McClung Museum at the University of Tennessee, Knoxville. Arthur E. Bogan is curator of aquatic invertebrates at the North Carolina State Museum of Natural Sciences, Raleigh.

Download or read book Delta Empire written by Jeannie Whayne and published by LSU Press. This book was released on 2011-12-05 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Delta Empire: Lee Wilson and the Transformation of Agriculture in the New South Jeannie Whayne employs the fascinating history of a powerful plantation owner in the Arkansas delta to recount the evolution of southern agriculture from the late nineteenth century through World War II. After his father’s death in 1870, Robert E. “Lee” Wilson inherited 400 acres of land in Mississippi County, Arkansas. Over his lifetime, he transformed that inheritance into a 50,000-acre lumber operation and cotton plantation. Early on, Wilson saw an opportunity in the swampy local terrain, which sold for as little as fifty cents an acre, to satisfy an expanding national market for Arkansas forest reserves. He also led the fundamental transformation of the landscape, involving the drainage of tens of thousands of acres of land, in order to create the vast agricultural empire he envisioned. A consummate manager, Wilson employed the tenancy and sharecropping system to his advantage while earning a reputation for fair treatment of laborers, a reputation—Whayne suggests—not entirely deserved. He cultivated a cadre of relatives and employees from whom he expected absolute devotion. Leveraging every asset during his life and often deeply in debt, Wilson saved his company from bankruptcy several times, leaving it to the next generation to successfully steer the business through the challenges of the 1930s and World War II. Delta Empire traces the transition from the labor-intensive sharecropping and tenancy system to the capital-intensive neo-plantations of the post–World War II era to the portfolio plantation model. Through Wilson’s story Whayne provides a compelling case study of strategic innovation and the changing economy of the South in the late nineteenth century.

Download or read book Human Intestinal Flukes written by Jong-Yil Chai and published by Springer Nature. This book was released on 2019-08-22 with total page 555 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides up-to-date information on the characteristics of each species of intestinal fluke found in humans and on the management of infections caused by these trematodes. Biology, epidemiology, host-parasite relationships, pathogenicity, clinical aspects, diagnosis, and treatment are all reviewed in detail. The zoonotic intestinal flukes comprise 38 genera belonging to 16 families. They are morphologically diverse and each species has a characteristic life cycle and geographical distribution. Intestinal fluke infections are commonly considered as tropical endemic diseases in Asian countries, where 6 million people are infected, but the geographical limits and populations at risk are expanding and changing owing to a range of factors, including growing international markets, improved transportation systems, changes in eating habits, demographic trends, and climate change. While the pathogenicity of intestinal flukes is generally mild, the impact in immunocompromised individuals requires clarification and some diagnostic problems remain to be solved. In exploring all aspects of human intestinal fluke infections, this book will be invaluable for clinicians and researchers alike.
