Available in PDF, EPUB and Kindle. Book excerpt: The medicinal properties of plants have been of interest to society for centuries and continue to be a subject of modern research. Yet too often research has been predicated upon poorly identified plant material and secondary sources of information. Much of what we know about the use of plants as drugs, poisons, foods, and as instruments of magical or religious practice derives from lore inherited from the clay tablets and papyri of the ancients and from compilations of early Greek, Arabic, and Indian physicians. Meanwhile, information pertaining to plant parts used even now in the daily life of peoples far removed from the influence of modern medical and health practices has been largely overlooked. With the encroachment of civilized cultures on primitive societies, unique traditions—often unwritten—are being destroyed. In many instances, the very plants involved are disappearing. Not infrequently, the only record, where one exists at all, of these vanishing pools of knowledge is that of the botanical field worker. For no matter what chemical or biological investigations may follow, the botanist can affix to an actual specimen, as he collects it in the field, the local terms applied to the plant and a description of native medicinal or other uses. Dr. Altschul has compiled field notes of health and medical interest on over 5,000 species of plants, culled from some 2,500,000 specimens of higher plants collected by field botanists from all over the world and deposited in the combined collections of the Arnold Arboretum and Gray Herbarium of Harvard University. The resulting catalogue represents a unique approach to supplying new investigational leads to researchers seeking biologically active plant principles. Dr. Altschul's meticulous sheet&ndashby–sheet examination of the Harvard collections provides the pharmacognosist, pharmacologist, and others in the medical and health sciences with an extensive firsthand survey of the domestic medicines of many cultures. These previously unpublished botanists' notes are here made available in a comprehensive publication that should become an important resource for every investigation into the area of medicinal phytochemistry. Indexes to families and genera are provided, as well as a medical index referring to diseases and to therapeutic properties for researchers intent on locating plants with special medicinal capacities. The author is a Research Fellow at the Botanical Museum of Harvard University.

Download or read book Flora of the Marquesas Islands set of Volumes 1 And 2 written by David Lorence and published by . This book was released on 2019-12-30 with total page 1135 pages. Available in PDF, EPUB and Kindle. Book excerpt: A project spanning over three decades has come to fruition with the publication of the Flora of the Marquesas Islands authored by David H. Lorence (NTBG) and Warren L. Wagner (Smithsonian Institution). This two volume, 1135 page opus is a complete account of all of the vascular plants found in the Marquesas Islands and was developed and written on a web site format. The Marquesas are a volcanic archipelago of 12 islands and numerous islets situated within the eastern part of French Polynesia, making it one of the most isolated groups of oceanic islands. This collaborative project between the National Tropical Botanical Garden, the Smithsonian Institution, and the Délégation à la Recherche de la Polynésie française is intended to further knowledge of the flora of this remote archipelago.Volume 1 (411 pages, published in December 2019) includes introductory chapters covering the project's history, Marquesas geology and climate, history of plant collecting in the islands, flora and vegetation, plant communities, threats to the flora, conservation status of species including IUCN Red List recommendations, critical conservation considerations, and many other aspects, as well as taxonomic treatments of the native and naturalized lycophytes (fern allies), ferns, and monocots. Volume 1 is richly illustrated with 134 figures including 111 color plates, 21 elegant line drawings by Smithsonian illustrator Alice Tangerini, and two maps. A complete list of all exsiccatae (specimens studied) is given in the Exsiccatae section. Volume 2 (722 pages, published in September 2020) covers the dicots, dicot exsiccatae, a list of cultivated plants, a list of all literature cited, and an index to both volumes. Volume 2 comprises is richly illustrated with 252 color figures and line drawings.

Download or read book Nutrient Cycling and Limitation written by Peter M. Vitousek and published by Princeton University Press. This book was released on 2018-06-26 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: The availability or lack of nutrients shapes ecosystems in fundamental ways. From forest productivity to soil fertility, from the diversity of animals to the composition of microbial communities, nutrient cycling and limitation are the basic mechanisms underlying ecosystem ecology. In this book, Peter Vitousek builds on over twenty years of research in Hawai'i to evaluate the controls and consequences of variation in nutrient availability and limitation. Integrating research from geochemistry, pedology, atmospheric chemistry, ecophysiology, and ecology, Vitousek addresses fundamental questions: How do the cycles of different elements interact? How do biological processes operating in minutes or hours interact with geochemical processes operating over millions of years? How does biological diversity interact with nutrient cycling and limitation in ecosystems? The Hawaiian Islands provide the author with an excellent model system for answering these questions as he integrates across levels of biological organization. He evaluates the connections between plant nutrient use efficiency, nutrient cycling and limitation within ecosystems, and nutrient input-output budgets of ecosystems. This book makes use of the Hawaiian ecosystems to explore the mechanisms that shape productivity and diversity in ecosystems throughout the world. It will be essential reading for all ecologists and environmental scientists.
Download or read book Measuring Biological Diversity written by Anne E. Magurran and published by John Wiley & Sons. This book was released on 2013-04-18 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: This accessible and timely book provides a comprehensive overview of how to measure biodiversity. The book highlights new developments, including innovative approaches to measuring taxonomic distinctness and estimating species richness, and evaluates these alongside traditional methods such as species abundance distributions, and diversity and evenness statistics. Helps the reader quantify and interpret patterns of ecological diversity, focusing on the measurement and estimation of species richness and abundance. Explores the concept of ecological diversity, bringing new perspectives to a field beset by contradictory views and advice. Discussion spans issues such as the meaning of community in the context of ecological diversity, scales of diversity and distribution of diversity among taxa Highlights advances in measurement paying particular attention to new techniques such as species richness estimation, application of measures of diversity to conservation and environmental management and addressing sampling issues Includes worked examples of key methods in helping people to understand the techniques and use available computer packages more effectively

Download or read book Plants on Plants The Biology of Vascular Epiphytes written by Gerhard Zotz and published by Springer. This book was released on 2016-09-01 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book critically reviews advances in our understanding of the biology of vascular epiphytes since Andreas Schimper’s 1888 seminal work. It addresses all aspects of their biology, from anatomy and physiology to ecology and evolution, in the context of general biological principles. By comparing epiphytes with non-epiphytes throughout, it offers a valuable resource for researchers in plant sciences and related disciplines. A particular strength is the identification of research areas that have not received the attention they deserve, with conservation being a case in point. Scientists have tended to study pristine systems, but global developments call for information on epiphytes in human-disturbed systems and the response of epiphytes to global climate change.
