Download or read book The Fusarium Laboratory Manual written by John F. Leslie and published by John Wiley & Sons. This book was released on 2008-02-28 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the first time in over 20 years, a comprehensive collection of photographs and descriptions of species in the fungal genus Fusarium is available. This laboratory manual provides an overview of the biology of Fusarium and the techniques involved in the isolation, identification and characterization of individual species and the populations in which they occur. It is the first time that genetic, morphological and molecular approaches have been incorporated into a volume devoted to Fusarium identification. The authors include descriptions of species, both new and old, and provide protocols for genetic, morphological and molecular identification techniques. The Fusarium Laboratory Manual also includes some of the evolutionary biology and population genetics thinking that has begun to inform the understanding of agriculturally important fungal pathogens. In addition to practical “how-to” protocols it also provides guidance in formulating questions and obtaining answers about this very important group of fungi. The need for as many different techniques as possible to be used in the identification and characterization process has never been greater. These approaches have applications to fungi other than those in the genus Fusarium. This volume presents an introduction to the genus Fusarium, the toxins these fungi produce and the diseases they can cause. "The Fusarium Laboratory Manual is a milestone in the study of the genus Fusarium and will help bridge the gap between morphological and phylogenetic taxonomy. It will be used by everybody dealing with Fusarium in the Third Millenium." --W.F.O. Marasas, Medical Research Council, South Africa

Download or read book A Little Corner of Freedom written by Douglas R. Weiner and published by Univ of California Press. This book was released on 1999-02-26 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: While researching Russia's historical efforts to protect nature, Douglas Weiner unearthed unexpected findings: a trail of documents that raised fundamental questions about the Soviet political system. These surprising documents attested to the unlikely survival of a critical-minded, scientist-led movement through the Stalin years and beyond. It appeared that, within scientific societies, alternative visions of land use, resrouce exploitation, habitat protection, and development were sustained and even publicly advocated. In sharp contrast to known Soviet practices, these scientific societies prided themselves on their traditions of free elections, foreign contacts, and a pre-revolutionary heritage. Weiner portrays nature protection activists not as do-or-die resisters to the system, nor as inoffensive do-gooders. Rather, they took advantage of an unpoliced realm of speech and activity and of the patronage by middle-level Soviet officials to struggle for a softer path to development. In the process, they defended independent social and professional identities in the face of a system that sought to impose official models of behavior, ethics, and identity for all. Written in a lively style, this absorbing story tells for the first time how organized participation in nature protection provided an arena for affirming and perpetuating self-generated social identities in the USSR and preserving a counterculture whose legacy survives today.

Download or read book The Names of Plants written by D. Gledhill and published by Cambridge University Press. This book was released on 1989-06-15 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides both a handy reference to the scientific names of plants and a clearly written account of the ways in which the naming of plants has changed with time and why these changes were necessary. It deals with the problems of using common names for plants against the historical background of our increasing discrimination of kinds of plants. It then goes on to consider landmarks in the standardization of both common and 'scientific' names and the development of internationally agreed principles governing the format and use of names in botany, sylviculture, agriculture and horticulture. From the alphabetical list the reader may interpret the scientific names of plants from any part of the world. For this second edition a number of changes and corrections in both parts have been made. The author has attempted to keep the first part acceptable to the amateur gardener by resisting a temptation to make it a definite guide to the International Code of Botanical Nomenclature. Others have done this already and with great clarity. Revision has allowed the inclusion of a brief comment on both synonymous and illegitimate botanical names and reference to recent attempts to accommodate the various traits and interests in the naming and names of cultivated plants.

Download or read book The Awakening Desert written by Michael Evenari and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: Michael Evenari's biography unfolds his exciting, manifold life: his love for botany, the confrontation with political events as a youngster and his thrilling experience of helping in the development of Israel. Evenari takes us on his exciting expeditions in the company of his beloved wife. He tells us of his meetings with many personalities and about his farm in the Negev. The discovery of long forgotten floodwater irrigated farm systems from the times of King Salomon and their reconstruction became a successful experiment which lead him to teach this approach of runoff agriculture in many parts of the world, initializing progress in the development of various arid areas. As a tribute to his successful scientific life, Evenari was awarded the Balzan Prize in 1988. In April 1989, Michael Evenari died at the age of 84.

Download or read book The Century of the Gene written by Evelyn Fox KELLER and published by Harvard University Press. This book was released on 2009-06-30 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a book that promises to change the way we think and talk about genes and genetic determinism, Evelyn Fox Keller, one of our most gifted historians and philosophers of science, provides a powerful, profound analysis of the achievements of genetics and molecular biology in the twentieth century, the century of the gene. Not just a chronicle of biology’s progress from gene to genome in one hundred years, The Century of the Gene also calls our attention to the surprising ways these advances challenge the familiar picture of the gene most of us still entertain. Keller shows us that the very successes that have stirred our imagination have also radically undermined the primacy of the gene—word and object—as the core explanatory concept of heredity and development. She argues that we need a new vocabulary that includes concepts such as robustness, fidelity, and evolvability. But more than a new vocabulary, a new awareness is absolutely crucial: that understanding the components of a system (be they individual genes, proteins, or even molecules) may tell us little about the interactions among these components. With the Human Genome Project nearing its first and most publicized goal, biologists are coming to realize that they have reached not the end of biology but the beginning of a new era. Indeed, Keller predicts that in the new century we will witness another Cambrian era, this time in new forms of biological thought rather than in new forms of biological life.

Download or read book The Biology of Camel Spiders written by Fred Punzo and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: My initial interest in the Solifugae (camel-spiders) stems from an incident that occurred in the summer of 1986. I was studying the behavioral ecology of spider wasps of the genus Pepsis and their interactions with their large theraphosid (tarantula) spider hosts, in the Chihuahuan Desert near Big Bend National Park, Texas. I was monitoring a particular tarantula burrow one night when I noticed the resident female crawl up into the burrow entrance. Hoping to take some photographs of prey capture, I placed a cricket near the entrance and waited for the spider to pounce. Suddenly, out of the comer of my eye appeared a large, rapidly moving yellowish form which siezed the cricket and quickly ran off with it until it disappeared beneath a nearby mesquite bush. So suddenly and quickly had the sequence of events occurred, that I found myself momentarily startled. With the aid of a headlamp I soon located the intruder, a solifuge, who was already busy at work macerating the insect with its large chelicerae (jaws). When I attempted to nudge it with the edge of my forceps, it quickly moved to another location beneath the bush. When I repeated this maneuver, the solifuge dropped the cricket and lunged at the forceps, gripping them tightly in its jaws, refusing to release them until they were forcefully pulled away.

Download or read book Flower Seeds written by M. B. McDonald and published by Cabi. This book was released on 2005-01-01 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: The floral industry represents a significant proportion of agricultural income in several developed countries, particularly the USA, the Netherlands and Japan. Hitherto, the sheer diversity of flower seeds, in their form, function and biology, has hindered the production of a comprehensive treatment of the topic. This book provides a unique and much-needed resource of information on the biology and technology of flower seeds. It presents in-depth information on the history and evolution of the ornamental and wild flower seed industries followed by recommendations for successful breed and production programs. A comprehensive coverage of the biology of flower seeds is considered as well as appropriate technologies associated with germination, vigor and viability testing. In this volume, the first of its kind, international authorities from academia and industry have been brought together to provide a comprehensive reference resource for both practitioners and students of seed science and technology and of ornamental horticulture.

Download or read book Greek Science of the Hellenistic Era written by Georgia L. Irby-Massie and published by Routledge. This book was released on 2013-02-01 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: We all want to understand the world around us, and the ancient Greeks were the first to try and do so in a way we can properly call scientific. Their thought and writings laid the essential foundations for the revivals of science in medieval Baghdad and renaissance Europe. Now their work is accessible to all, with this invaluable introduction to c.100 scientific authors active from 320 BCE to 230 CE. The book begins with an outline of a new socio-political model for the development and decline of Greek science, followed by eleven chapters that cover the main disciplines: * the science which the Greeks saw as fundamental - mathematics * astronomy * astrology and geography * mechanics * optics and pneumatics * the non-mathematical sciences of alchemy, biology, medicine and 'psychology'. Each chapter contains an accessible introduction on the origins and development of the topic in question, and all the authors are set in context with brief biographies.
