Download or read book State of the World s Forests 2009 written by Food and Agriculture Organization of the United Nations and published by Fao. This book was released on 2009 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published biennially, this title offers a global view of major developments affecting forests. It places more emphasis on the 'demand side': What will be the impact on forests of future increases in global population, economic development and globalization? "State of the World's Forests", published biennially, provides a global view of major developments affecting forests. The theme for the 2009 edition is 'Society, forests and forestry: adapting for the future'. The 2007 issue reviewed 'Progress towards sustainable forest management' with an emphasis on the 'supply side', in particular forest resources. "State of the World's Forests 2009" places more emphasis on the 'demand side': What will be the impact on forests of future increases in global population, economic development and globalization? Is the explosion in global trade having positive or negative effects on the world's forests? Will the forest sector continue to have a major role in providing livelihoods for rural communities? This eighth edition looks forward. Part One summarizes the outlook for forests and forestry in each region of the world. FAO periodically carries out regional forest sector outlook studies in collaboration with countries and organizations in each region. The results of studies for all regions are summarized and presented here for the first time in a single publication. A main pattern that emerges is a strong correlation between economic development and the state of forests. Countries that are undergoing rapid economic growth tend to struggle with immense pressures on their forests. In contrast, regions that have already achieved a high level of economic development are usually able to stabilize or increase their forest area. However, the factors affecting forests are numerous and complex, making it difficult to draw simple conclusions or to make reliable projections. Part Two considers how forestry will have to adapt for the future. It begins with a global outlook for wood products demand to 2030, noting changing patterns in production, consumption and trade. Next, a chapter on environmental services of forests probes the various market and non-market mechanisms evolving to help forests and trees fulfill their environmental service functions of land, water and biodiversity protection, carbon storage and others. A look at progress in institutional adaptation notes that many forestry institutions are having difficulty in adapting to rapid changes in communications, globalisation and society's expectations. Those institutions that are willing and able to adapt are more likely to be successful in the future. Finally, Part Two examines developments in science and technology, which will continue to have an enormous impact on the future of forests and forestry. Imagine a world in which trees are a major source of fuel for cars, replacing oil. Only a few years ago this seemed like fantasy, but today the possibility must be seriously considered.

Download or read book Plants that Fight Cancer Second Edition written by Spyridon E. Kintzios and published by CRC Press. This book was released on 2019-06-26 with total page 519 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants that Fight Cancer, Second Edition, is a compilation that reviews cancer treatment and research-based information on the plant kingdom as the source of both known and novel chemical moieties and mixtures, many of them still under identification. This new edition follows the organization of the first book with a considerable expansion of content that more than doubles the volume of information. Divided into four segments, the first part is dedicated to a review of our current knowledge of cancer, the different types and incidence, the molecular pathways of the disease, and the various treatment protocols, with an emphasis on chemotherapy. The second part is a brief journey in pharmacognosy, with detailed information about each of the fourteen different chemical groups of plant secondary metabolites, their use in cancer chemotherapy, and updated information on the biotechnological production of the most representative compounds in clinical practice. The third part of the book comprises six chapters dedicated to either plant chemotherapeutical approaches to specific cancer types (e.g. bladder, prostate) or specific groups of plant secondary metabolites with novel and promising properties for cancer treatment (e.g. naphthoquinones, lectins, phenanthridone alkaloids). The fourth part, containing investigative information on almost 300 individual plant species with established anticancer properties, either on a clinical or in vitro level, is with no doubt the most analytical. This new edition contains chapters on cytotoxic phenanthridone alkaloid constituents of the Amaryllidaceae; naphthoquinone-contained anticancer terrestrial plants; polyphenols and cancer immunology; medicinal plant product-based fabrication nanoparticles (Au and Ag) and their anticancer effects; bladder and prostate cancer; and plant lectins in cancer treatment. FEATURES • Provides efficient information for all kinds of cancer and plant chemotherapeutical approaches to specific cancer types • Discusses specific groups of plant secondary metabolites with novel and promising properties for cancer treatment • Provides scientific information for medicinal uses of various plants • Contains analytical information on almost 300 individual plant species with established anticancer properties, either on a clinical or in vitro level • Focuses on plant genera and species that are either already used in cancer chemotherapy or have been identified with antitumor and antileukemic properties to a bigger or lesser extent

Book excerpt: This is a textbook providing basic data about the crop pests and the damage they inflict throughout the tropics and sub-tropics. Each major pest is illustrated by either a line drawing or a photograph, and sometimes the damage can also be seen. A world distribution map is provided for each species. Control measures tend to be general rather than very specific. Most of the pests are insects and mites, but some nematodes, molluscs, birds and mammals are included.
Download or read book Histological Techniques written by M. Gabe and published by Springer. This book was released on 2012-02-07 with total page 1108 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'Eyw rpwvry ~OiWTO~ EV Tli E(}'rllup JOHN, J, 23 A SURVEY OF THE PRINCIPAL WORKS on histological technique that have th appeared since the end of the 19 century shows such a diversity of concept and directive ideas, in spite of the fundamental unity of subject, that the choice of the underlying orientation was perhaps the most difficult problem facing me when MM. Masson & Cie, requested me to write this book. A classification of these works based on their particular orientation and carrying the excess inherent in all that is schematic would lead to the definition of three types of books. Some are handbooks or treatises on "microscopy". They are tacitly limited to the biological applications of the microscope, all of which are reviewed, and include in the same volume the techniques of histology proper along with those of bacteriology, botany and embryology. Such a work, on the scale of an encyclopaedic treatise contributed by specialists from a number of discip lines and meant to be consulted as a dictionary, may have a certain value if it is really exhaustive and periodically revised. But it is no longer possible on the scale of a handbook. A single person, however gifted, cannot have acquired sufficient mastery over all the techniques of the above disciplines to be able to speak from personal experience.

Book excerpt: Plants as Medicine.... A Natural Approach to Self-Health Medical Botany: Plants Affecting Man?s Health, Walter H. Lewis, Memory P.F. Elvin-Lewis Medical Botany is a fascinating look at the facts and fictions surrounding plants and man?not only which plants affect our bodies, but how they affect them. Authoritative, rich in anecdote and lore, lavishly illustrated, this encyclopedic reference brings within your reach the curative, healing, poisonous, allergenic, and psychoactive properties of thousands of plants. Its ready reference format allows you to turn instantly to information about a specific plant?s properties, its history, its use in orthodox medicine (where applicable) and its use in folk medicine. Discover a wealth of information on plants that have been used for such purposes as to treat peptic ulcers, to assist in the fight against cancer (in combination with chemotherapy), to help alleviate gout and diabetes, and to promote the healing of wounds. Each section begins with historical background of the plants discussed, with colorful stories ranging from Socrates? fatal hemlock to Timothy Leary?s experiments. There are informative discussions of how your body works, with sections covering heart and circulation, metabolism, nervous system, urogenital system, gastrointestinal tract, allergies, ear, internal poisons, and more. This intriguing compendium/reference will enlighten, entertain, and give you a healthier knowledge of plants. Praise for Medical Botany... "Skillfully organized, neatly written, highly informative, and well illustrated, this is a stimulating and useful reference volume. It is not a mere catalog of medicinal plants but a carefully prepared review of injurious, healing and nourishing, and psychoactive plants...should be a lasting joy for reference and a source of continued satisfaction..." ?American Scientist "I would recommend this text highly...useful for the layman who wishes an introduction to the topic. The authors have provided a fresh look at a classic subject and should be commended for their efforts." ?Economic Botany "...a vast compendium of information on medically important plants, both harmful and useful...commendable." ?New England Journal of Medicine
Download or read book Polyploidy written by Walter H. Lewis and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polyploidy as a dramatic mutational event in the process of evolution has wide implications in nature and for the generation of new and improved crops. The three day Conference on POLYPLOIDY: BIOLOGICAL RELEVANCE focused on three aspects of this natural phenomenon: the first emphasized the characteristics of polyploidy, the second described the occurrence of polyploidy among plants and animals, and the third considered past and future areas of both fundamental and pragmatic research that involve polyploidy. New information relative to origin, cytogenetics, ecology, physiology, biochemistry, and populational studies stress the need to reexamine current views on the origins of polyploidy and its significance among both plants and animals. There are major differences in the occurrence of polyploidy between. plant groups and it is proving a much more common event among bisexual vertebrates than heretofore considered possible. Crop development and improvement must utilize approaches based fundamentally on more natural systems; in fact future research should focus more on polyploidy as a natural phenomenon that needs study at all levels of endeavor from field-oriented populational aspects to sophisticated molecular analyses and genome manipulations. This volume provides a summary of current knowledge of polyploidy pertinent to botanists, zoologists, and agriculturists who are interested in the evolution o~natural systems and who are concerned with the contribution that crop improvement can make to human well-being. Walter H. Lewis St. Louis, Missouri October, 1979 v ACKNOWLEDGMENTS The Host Committee thanks all speakers and moderators for their generous contribution to the Conference and to this volume.
