View Rights PortalWith an estimated 35,000 species, terrestrial molluscs are one of the most successful and diverse animal groups in land-based ecosystems. These animals have long been of importance to human societies as food, medicine, crop pests, vectors of parasites, and as tools, personal ornamentation and currency in trade. This book presents a synthesis of current knowledge and research on the biology of terrestrial molluscs.
Mollusc species currently constitute a major threat to sustainable agriculture. This threat is associated with cultivation of new crops, intensification of agricultural production systems and the spread through human trade and travel of species adapted to these modified environments. In some crops their significance is only now becoming apparent with the decline in the importance of other pest groups which can be effectively controlled. The book focuses on: toxicology of chemicals; deployment of molluscicides in baits; specific crop situations worldwide; current pest status of mollusc species and progress towards development of solutions.
This book provides the first coherent examination of the vast literature on the diversity of organisms that constitute the natural enemies of terrestrial molluscs. In a series of review chapters, it provides an authoritative synthesis of current research on predators, parasites and pathogens and how they might be used to control mollusc pests.

Rivers constitute a major tourism resource, providing spectacular settings, recreation facilities, a means of transport, a sense of heritage and adventure, and links with the environment and natural world. River tourism accounts for a significant proportion of the world’s tourism consumption, with activities such as Nile cruises and rafting holidays making it an economically important area of tourism demanding in-depth analysis. This book explores river tourism from a range of perspectives including uses, heritage, management, environmental concerns, and marketing
From alpha-galactosidases to xylanases, Enzymes in Farm Animal Nutrition provides a comprehensive guide to all aspects associated with enzyme-supplemented animal feeds. It details the history and size of the feed enzyme market, before describing how feed enzymes are manufactured and employed in monogastric, aqua and ruminant diets. This new edition explores considerable advances such as the use of enzymes in fish and shrimp diets, new understanding of how phytases function in the animal, NSPase research and enzymes' extended use in ruminant markets. It also: - Provides comprehensive coverage of all topics relating to the production, use, and co-operativity and analysis of feed enzymes; - Is fully updated throughout, revealing significant developments such as new methods to deliver enzymes (formulations, encapsulations, and liquid spray systems) and advances in enzyme analysis; - Includes brand new chapters on combinations of enzymes, antibiotic free diets and how to measure response in feed enzyme trials. Covering biochemistry, enzymology and characteristics relevant to animal feed use, this book forms a valuable resource for academics and students of animal nutrition and production, as well as professionals in the animal feed industry.
In the past decade, a number of advances have been made in genetic engineering as applied to farmed animals. This book has been developed from invited presentations at a conference held in California in August 1997 to address this issue. It is written by representatives from the leading laboratories involved in attempts to improve agriculturally important mammals, poultry and fish. Current knowledge, methodology, technical improvements and successes in the applications of transgenic technology to a range of animals which are important in agriculture are brought together for the first time under one cover. This book is essential reading for research workers in animal genetics, breeding and biotechnology.
Dem Nobelpreisträger Eric R. Kandel gebührt das Verdienst, das bis dahin gänzlich unerkundete Gebiet der Beziehungen zwischen Neurobiologie und Psychoanalyse erschlossen zu haben. Heute ist es eines der spannendsten und zugleich innovativsten Felder der Wissenschaften überhaupt. Eric R. Kandel, der, in Österreich geboren und aufgewachsen, in der Zeit des Nationalsozialismus in die Vereinigten Staaten emigrierte, hat fraglos diesem Wissenschaftszweig die maßgeblichen Impulse gegeben. Kaum ein anderer Bereich hat derart spektakuläre Forschungsergebnisse vorzuweisen, die zugleich unser Bild des Menschen revolutionieren, wie etwa die aufsehenerregende Entdeckung eines funktionellen Wandels einzelner Gehirnareale nach einer Psychotherapie. Die vorliegende Sammlung von Aufsätzen Eric R. Kandels lädt den Leser zu "einer der wichtigsten, bedeutsamsten und aufregendsten Forschungsreisen unserer Zeit ein" (Stuart C.Yudofsky): zu einer Erkundung der Funktionsweise des menschlichen Gehirns und der Möglichkeiten, durch die Psychoanalyse und die Psychiatrie auf diese Einfluß zu nehmen. Die leitende Idee ist dabei, daß ein Verständnis der biologischen Prozesse, die unser Lernen und Verhalten begleiten, auch entscheidend zu unserem Verständnis des Verhaltens und seiner Störungen beitragen kann. Der Band, den der Protagonist der deutschen Hirnforschungsdebatte Gerhard Roth einleitet und der mit einer sehr persönlichen Einführung Eric R. Kandels beginnt, bietet einen konzisen Überblick dieser Revolution der psychiatrischen Forschung.

It contains essential information for policymakers, planners, researchers, managers and operators within the tourism industry.
As the longest canal in the world, the Grand Canal connects five rivers in the land of China. This human-made river not only witnessed history of several dynasties, but also made great contribution to the economic, cultural, and political unification of the southern and northern China. This title explores large amount of historical materials concerning the Grand Canal, picturing a complete record of the canal during 2000 years.
The world is about to hit a population level of EIGHT BILLION people on one small planet. Through Allen’s analysis of the situation, the realization sets in that the fights by environmental and world aid groups are all for naught as every gain is soon overwhelmed by the pressures of more growth. Our planet's greatest threat is of too many people depleting the Earth's resources and contributing to climate change. Allen offers a thorough analysis of our environmental, social, political, and economic crises; then offers a treasure trove of solutions and success stories that we can all take to heart.
