Book excerpt: Excerpt from Effects of Ozone and Sulfur Dioxide on Height and Stem Specific Gravity of Populus Hybrids At the end of the treatment period, the height of each plant was measured and the specific gravity of the lower 10 cm of the stern was determined. Specific gravity is the ratio of the oven-dried weight of the stern section to the weight of the water that over flowed from a side-arrn test tube when the section was submerged. A one-way multivariate analysis of vari ance was performed on the data for each clone (morrison Where the union intersection test indicated rejection of the hypothesis of equal mean vectors, the de termination of whether both response vari ables were contributing to the rejection was made with a step-down analysis (kramer Simultaneous confidence intervals (95 percent) were calculated to compare the control mean to the fumigated means in each clone.

Download or read book Biodiversity and Human Health written by Francesca Grifo and published by Island Press. This book was released on 1997-02-01 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The implications of biodiversity loss for the global environment have been widely discussed, but only recently has attention been paid to its direct and serious effects on human health. Biodiversity loss affects the spread of human diseases, causes a loss of medical models, diminishes the supplies of raw materials for drug discovery and biotechnology, and threatens food production and water quality. Biodiversity and Human Health brings together leading thinkers on the global environment and biomedicine to explore the human health consequences of the loss of biological diversity. Based on a two-day conference sponsored by the National Institutes of Health, the National Science Foundation, and the Smithsonian Institution, the book opens a dialogue among experts from the fields of public health, biology, epidemiology, botany, ecology, demography, and pharmacology on this vital but often neglected concern. Contributors discuss the uses and significance of biodiversity to the practice of medicine today, and develop strategies for conservation of these critical resources. Topics examined include: the causes and consequences of biodiversity loss emerging infectious diseases and the loss of biodiversity the significance and use of both prescription and herbal biodiversity-derived remedies indigenous and local peoples and their health care systems sustainable use of biodiversity for medicine an agenda for the future In addition to the editors, contributors include Anthony Artuso, Byron Bailey, Jensa Bell, Bhaswati Bhattacharya, Michael Boyd, Mary S. Campbell, Eric Chivian, Paul Cox, Gordon Cragg, Andrew Dobson, Kate Duffy-Mazan, Robert Engelman, Paul Epstein, Alexandra S. Fairfield, John Grupenhoff, Daniel Janzen, Catherine A. Laughin, Katy Moran, Robert McCaleb, Thomas Mays, David Newman, Charles Peters, Walter Reid, and John Vandermeer. The book provides a common framework for physicians and biomedical researchers who wish to learn more about environmental concerns, and for members of the environmental community who desire a greater understanding of biomedical issues.

Download or read book Plant Aging written by Roberto Rodríguez and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: For many, the terms aging, maturation and senescence are synonymous and used interchangeably, but they should not be. Whereas senescence represents an endogenously controlled degenerative programme leading to plant or organ death, genetiC aging encompasses a wide array of passive degenerative genetiC processes driven primarily by exogenous factors (Leopold, 1975). Aging is therefore considered a consequence of genetiC lesions that accumulate over time, but by themselves do not necessarily cause death. These lesions are probably made more severe by the increase in size and complexity in trees and their attendant physiology. Thus while the withering of flower petals following pollination can be considered senescence, the loss of viability of stored seeds more clearly represents aging (Norden, 1988). The very recent book "Senescence and Aging in Plants" does not discuss trees, the most dominant group of plants on the earth. Yet both angiospermic and gymnospermic trees also undergo the above phenomena but less is known about them. Do woody plants senesce or do they just age? What is phase change? Is this synonymous with maturation? While it is now becoming recognized that there is no programmed senescence in trees, senescence of their parts, even in gymnosperms (e. g. , needles of temperate conifers las t an average of 3. 5 years), is common; but aging is a readily acknowledged phenomenon. In theory, at least, in the absence of any programmed senescence trees should -live forever, but in practice they do not.

Download or read book Trease and Evans' Pharmacognosy written by William Charles Evans and published by Elsevier Health Sciences. This book was released on 2009-05-27 with total page 3322 pages. Available in PDF, EPUB and Kindle. Book excerpt: This encyclopedic reference work on pharmacognosy covers the study of those natural substances, principally plants, that find a use in medicine. Its popularity and longevity stem from the book's balance between classical (crude and powdered drugs' characterization and examination) and modern (phytochemistry and pharmacology) aspects of this branch of science, as well as the editor's recognition in recent years of the growing importance of complementary medicines, including herbal, homeopathic and aromatherapy. No other book provides such a wealth of detail. A reservoir of knowledge in a field where there is a resurgence of interest - plants as a source of drugs are of growing interest both in complementary medicine fields and in the pharmaceutical industry in their search for new 'lead compounds'. Dr Evans has been associated with the book for over 20 years and is a recognised authority in all parts of the world where pharmacognosy is studied, his knowledge and grasp of the subject matter is unique. Meticulously referenced and kept up to date by the editor, new contributors brought in to cover new areas. New chapter on 'Neuroceuticals'. Addition of many new compounds recently added to British Pharmacopoeia as a result of European harmonisation. Considers development in legal control and standardisation of plant materials previously regarded as 'herbal medicines'. More on the study of safety and efficacy of Chinese and Asian drugs. Quality control issues updated in line with latest guidelines (BP 2007).

Available in PDF, EPUB and Kindle. Book excerpt: Chlorophyll a Fluorescence: A Signature of Photosynthesis highlights chlorophyll (Chl) a fluorescence as a convenient, non-invasive, highly sensitive, rapid and quantitative probe of oxygenic photosynthesis. Thirty-one chapters, authored by 58 international experts, provide a solid foundation of the basic theory, as well as of the application of the rich information contained in the Chl a fluorescence signal as it relates to photosynthesis and plant productivity. Although the primary photochemical reactions of photosynthesis are highly efficient, a small fraction of absorbed photons escapes as Chl fluorescence, and this fraction varies with metabolic state, providing a basis for monitoring quantitatively various processes of photosynthesis. The book explains the mechanisms with which plants defend themselves against environmental stresses (excessive light, extreme temperatures, drought, hyper-osmolarity, heavy metals and UV). It also includes discussion on fluorescence imaging of leaves and cells and the remote sensing of Chl fluorescence from terrestrial, airborne, and satellite bases. The book is intended for use by graduate students, beginning researchers and advanced undergraduates in the areas of integrative plant biology, cellular and molecular biology, plant biology, biochemistry, biophysics, plant physiology, global ecology and agriculture.
