Hydrology and Water Supply for Pond Aquaculture

When water is in short supply, the transpiration stream cannot deliver enough
water to leaf cells to maintain high turgor pressure ... Many theories have been
advanced to explain how water moves within the xylem from roots to leaves of
plants.

In 1979, several graduate students in the Department of Fisheries and Allied Aquacultures at Auburn University met with one of the authors (CEB) and asked him to teach a new course on water supply for aqua culture. They felt that information on climatology, hydrology, water distribution systems, pumps, and wells would be valuable to them. Most of these students were planning to work in commercial aquaculture in the United States or abroad, and they thought that such a cdurse would better prepare them to plan aquaculture projects and to communicate with engineers, contractors, and other specialists who often become involved in the planning and construction phases of aquaculture en deavors. The course was developed, and after a few years it was decided that more effective presentation of some of the material could be made by an engineer. The other author (KHY) accepted the challenge, and three courses on the water supply aspects of aquaculture are now offered at Auburn University. A course providing background in hydrology is followed by courses on selected topics from water supply engineering. Most graduate programs in aquaculture at other universities will even tually include similar coursework, because students need a formal intro duction to this important, yet somewhat neglected, part of aquaculture. We have written this book to serve as a text for a course in water supply for aquaculture or for individual study. The book is divided into is concerned two parts.

No book before this one has rendered the story of cigarettes -- mankind's most common self-destructive instrument and its most profitable consumer product -- with such sweep and enlivening detail. Here for the first time, in a story full of the complexities and contradictions of human nature, all the strands of the historical process -- financial, social, psychological, medical, political, and legal -- are woven together in a riveting narrative. The key characters are the top corporate executives, public health investigators, and antismoking activists who have clashed ever more stridently as Americans debate whether smoking should be closely regulated as a major health menace. We see tobacco spread rapidly from its aboriginal sources in the New World 500 years ago, as it becomes increasingly viewed by some as sinful and some as alluring, and by government as a windfall source of tax revenue. With the arrival of the cigarette in the late-nineteenth century, smoking changes from a luxury and occasional pastime to an everyday -- to some, indispensable -- habit, aided markedly by the exuberance of the tobacco huskers. This free-enterprise success saga grows shadowed, from the middle of this century, as science begins to understand the cigarette's toxicity. Ironically the more detailed and persuasive the findings by medical investigators, the more cigarette makers prosper by seeming to modify their product with filters and reduced dosages of tar and nicotine. We see the tobacco manufacturers come under intensifying assault as a rogue industry for knowingly and callously plying their hazardous wares while insisting that the health charges against them (a) remain unproven, and (b) are universally understood, so smokers indulge at their own risk. Among the eye-opening disclosures here: outrageous pseudo-scientific claims made for cigarettes throughout the '30s and '40s, and the story of how the tobacco industry and the National Cancer Institute spent millions to develop a "safer" cigarette that was never brought to market. Dealing with an emotional subject that has generated more heat than light, this book is a dispassionate tour de force that examines the nature of the companies' culpability, the complicity of society as a whole, and the shaky moral ground claimed by smokers who are now demanding recompense From the Trade Paperback edition.

In the history of the International Plant Nutrition Colloquium from its first meeting in 1954, this meeting, the 13th Colloquium, is the first to be held in Asia and will be the last in the 20th century. The 20th century has seen huge changes in the number and activities of mankind. Our population has increased from around 1. 7 billion to more than 5. 8 billion and technological innovations have completely altered our way of living. As a consequence of such rapid change, we are facing many problems including changes in our environment of a global scale. But, while food shortage has been a serious concern to mankind throughout our history, serious food shortages in the 20th century have been confined to limited times and areas. As Lester Brown discusses in this volume, farmers have increased food production heroically on demand. We, the plant nutritionists should be proud of our support to the world's farmers which has helped them make their achievement possible. During the 20th century, the science of plant nutrition also has achieved great progress as described by Jack Loneragan; it became established as a discipline firmly based in science, defined the chemical elements supporting plant growth, and has contributed to improvements in plant production and environmental quality, as readers will find in many contributions in this volume.

Forages should be the basis of all diets in horse feeding. Therefore it is of major importance to determine which parameters will influence their quality. Changes on chemical composition along the vegetative cycle, nutrient losses during harvesting, preservation and storage are factors that could have an effect on nutritive value, as well on digestibility and palatability. A specific grazing and ingesting behaviour, linked to plant preferences and the selection of feeding sites will have an impact on biodiversity. This will determine the options on plant species and varieties and further management of pastures for horses. This book highlights the role of forages and grazing in horse nutrition and also gathers information about related topics, such as the contribution of local breeds for the sustainability and development of rural areas, their impact on landscape and relationships with environmental preservation. This book is the 6th volume in a scientific series conceived through the European Workshop on Equine Nutrition (EWEN) which falls under the umbrella of the Horse Commission of the European Federation of Animal Science (EAAP). All these materials provide an interesting basis for further discussion, not only in specialized forums, but also for those involved in horse production.

While environmentalists insist that lower rates of consumption of natural resources are essential for a sustainable future, many economists dismiss the notion that resource limits act to constrain modern, creative societies. The conflict between these views tinges political debate at all levels and hinders our ability to plan for the future. Supply-Side Sustainability offers a fresh approach to this dilemma by integrating ecological and social science approaches in an interdisciplinary treatment of sustainability. Written by two ecologists and an anthropologist, this book discusses organisms, landscapes, populations, communities, biomes, the biosphere, ecosystems and energy flows, as well as patterns of sustainability and collapse in human societies, from hunter-gatherer groups to empires to today's industrial world. These diverse topics are integrated within a new framework that translates the authors' advances in hierarchy and complexity theory into a form useful to professionals in science, government, and business. The result is a much-needed blueprint for a cost-effective management regime, one that makes problem-solving efforts themselves sustainable over time. The authors demonstrate that long-term, cost-effective resource management can be achieved by managing the contexts of productive systems, rather than by managing the commodities that natural systems produce.

Septoria leaf blotch has been the major disease of wheat in Britain and much of the rest of Europe. It has been reported that the disease causes serious yield losses to range from 31 to 53%. Mycosphaerella graminicola (anamorph: Septoria tritici) is the pathogen which causes Septoria leaf blotch. The disease can be controlled by various methods such as cultural practices, chemical control, using resistant varieties and biological control. In plant pathology, the term biological control leads to the introduction of microbial antagonists or host specific pathogens to suppress diseases and populations of one or more plant pathogens. This study investigated the microbial community on and within wheat leaves which can suppress Septoria leaf blotch by reducing the inoculum level of the causative pathogen M. graminicola. Plate count and DGGE analysis techniques were used to assess the microbial community. The changes in the microbial populations of healthy, senescent and M. graminicola infected i.e. diseased wheat leaves were investigated in vitro on agar plates using plate colony count method. It was found that method was successful in assessing both bacterial and fungal population sizes showing distinct colonies. DGGE is a rapid method which can analyze large number of samples simultaneously. The bands appearing in DGGE profile represent different species present in the microbial population. The DGGE technique was successfully used in this study to assess bacterial community. Bioinformatics tools have also played a vital role in this study for identifying bacterial and fungal species. A total of five bacterial species and five fungal species were identified by bioinformatics tools. The antagonistic abilities of identified bacterial and fungal species were tested against a Septoria isolate in vitro on dual culture PDA plates. Four microorganisms (Fusarium sp., Verticillium sp., Penicillium sp., Sporobolomyces sp. and Microbotryum sp.) in the dual cultures vary in their colony length, width, ratio of length and width and distance bwtween them. But after statistical analysis all the values are insignificant observations of dual culture plates indicated that the microorganisms might inhibit Septoria by competing for space. These microorganisms after testing might be good candidates for further in vivo testing of Septoria inhibition. A thorough knowledge of wheat leaf microbial communities is required for further use of biocontrol in the future.

The first edition of this book was the first to provide an integrated description of sap ascension from an anatomical and functional point of view. The second edition opens with the three-dimensional aspects of wood anatomy. The cohesion-tension theory and new evidence are introduced in response to recent controversies over the mechanism of sap ascent in plants. The physiology, anatomy and biophysics of xylem dysfunction are discussed and new insights into hydraulic architecture are reviewed with special emphasis on physiological limits on maximum transpiration and how hydraulic architecture limits gas exchange, carbon gain and growth of plants. The text concludes with a description of xylem failure and pathology. The book highlights fascinating areas of current research with the aim to stimulate more work in the future.
