    Description:  The book begins with an introduction to vegetative propagation, which includes growing plants from cuttings as well as from grafts. It provides a brief history of the subject, explains how grafting works and shows why it is now the preferred technique for propagating most commercial plants. The following chapter introduces the reader to the tools that are needed and the basics of budding, grafting and multi-grafting.

    It gives step-by-step instructions for making grafts, advice on selecting scion wood, production and preparation of rootstocks and after-care of grafted plants. Separate chapters on budding and grafting describe the complete range of methods that can be used. The budding chapter covers T-budding, chip budding, patch budding and V-budding. The chapter on grafting covers the splice graft, wedge graft, whip and tongue graft, side graft, approach graft, seed grafting, grafting of herbaceous plants, machine bench grafting and top working established trees. The remainder of the book has separate entries discussing the preferred method of propagation for each of the plant species.

    Description:  The second edition of this book is created to assist the clinician in the initial response to the needs of a child or adult exposed to a poisonous or injurious plant. It lists common plants that might lead to the development of the symptom complex and describes the mechanisms of action of the implicated toxin, additional clinical manifestations, and specific therapeutics for each presentation. It has methodically enhanced the previous edition’s botanical rigor with insights from both pharmacognosy and clinical medicine to make it a truly comprehensive source for anyone who has an interest in plants.

    Description:  The Handbook of Plant Nutrition provides a readily accessible source of highly current and reliable information on the nutritional requirements of the most significant crops being cultivated worldwide. With their introduction, the editors provide an overview of plant nutrients and beneficial elements, distinguishing the difference between the two, and explaining research approaches and diagnostic criteria currently being applied.

    What then follows are twenty chapters, each one dedicated to an essential macro or micronutrient or beneficial element. Written by eminent researchers from across the world, each of the chapters-
    Offers historical information on the specific nutrient, explaining why it is either essential or a beneficial element, giving demonstration of its essentiality and functions in plants
    Explains how appearance and composition of plants can be used to assess nutritional status
    Discusses the value of soil tests for assessing nutritional status
    Recommends fertilizers that can be applied to remedy nutritional deficiencies

    Description:  The astonishing biography of a mineral that can sustain our world- or destroy it

    Uranium occurs naturally in the earth's crust-yet holds the power to end all life on the planet. This is its fundamental paradox, and its story is a fascinating window into the valor, greed, genius, and folly of humanity. A problem for miners in the Middle Ages, an inspiration to novelists and a boon to medicine, a devastat­ing weapon at the end of World War II, and eventually a polluter, killer, excuse for war with Iraq, potential deliverer of Armageddon and a possible last defense against global warming-Uranium is the riveting story of the most powerful element on earth, and one which will shape our future, for better or worse.

    Description:  This is the first book to describe the ecology of high latitude lakes, rivers and glacial environments in both the North and South polar regions. From the lake-rich floodplains of the Arctic to the deep, enigmatic waters of Lake Vostok, Antarctica, these regions contain some of the most extraordinary aquatic ecosystems on Earth. They provide a fascinating diversity of habitats for plant, animal and microbial communities, and are proving to be valuable model systems for exploring many ecological themes including landscape-lake interactions, adaptation of life to environmental extremes, and controls on the structure and functioning of aquatic ecosystems.

    Some of these waters also have direct global implications, including permafrost thaw lakes as sources of greenhouse gases, subglacial aquatic environments as a storehouse of ancient microbes, and Arctic rivers as major inputs of freshwater and organic carbon to the World Ocean. Given that many polar areas are experiencing greater climate warming than at lower latitudes, these ecosystems can also be viewed as sentinels of global change.

    This timely volume brings together many of the world's leading researchers in polar limnology to describe these diverse aquatic environments and their ecology. It introduces each major ecosystem type, examines the similarities and differences between Arctic and Antarctic systems as well as their responses to environmental change, and describes new frontiers for future research. A glossary of terms is provided for non-specialists, and a set of colour plates introduces the ecosystems and their biota.

    Description:  Paleomagnetism is the study of the fossil magnetism in rocks. It has been paramount in determining that the continents have drifted over the surface of the Earth throughout geological time. The fossil magnetism preserved in the ocean floor has demonstrated how continental drift takes place through the process of sea-floor spreading. The methods and techniques used in paleomagnetic studies of continental rocks and of the ocean floor are described and then applied to determining horizontal movements of the Earth's crust over geological time. An up-to-date review of global paleomagnetic data enables 1000 million
    years of Earth history to be summarized in terms of the drift of the major crustal blocks over the surface of the Earth.

    * Details the theory and methodology of rock magnetism, with particular emphasis on intrepreting crustal movements from continental and oceanic measurements
    * Outlines Earth history for the past 1000 million years, from the Rodinia super-continent through its breakup and the formation of Gondwana to the formation and breakup of Pangea and the amalgamation of Eurasia
    * Provides a comprehensive treatment of oceanic paleomagnetism
    * Provides a set of color pateogeographic maps covering the past 250 million years
    * Written by two internationally recognized experts in the field
