Available in PDF, EPUB and Kindle. Book excerpt: I investigated the suspected polytypic nature of the green cascade frog, Rana livida, from southeast Asia with a multi-step approach. My initial anatomical study of specimens from Vietnam resulted in the recognition of three distinct species and five morphological groups. I tested the strength of these groupings with morphometrics and cellular DNA content analysis. Congruence among the results of morphology, morphometrics, and cellular DNA content, led me to suspect the presence of further cryptic species. I tested this hypothesis with allozyme electrophoresis, resolving 15 presumptive loci. Fixed allelic differences suggested the presence of four additional species. They also suggested that one of the new species may be two distinct species, but the evidence collected here is equivocal. I elucidated seven species of the Rana livida complex. I believe that much more cryptic diversity of this complex and other cascade ranids await discovery. This highlights the need for rigorous taxonomic and phylogenetic analyses of all cascade ranids.
Download or read book The Cerrados of Brazil written by Paulo S. and published by Columbia University Press. This book was released on 2013-02-05 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: The massive grasslands of Brazil -- known as the cerrados -- which cover roughly a quarter of its land surface and are among the most threatened regions in South America, have received little media attention. This book brings together leading researchers on the area to produce the first detailed account in English of the natural history and ecology of the cerrado/savanna ecosystem. Given their extent and threatened status, the richness of their flora and fauna, and the lack of familiarity with their unique ecology at the international level, the cerrados are badly in need of this important and timely work.
Download or read book Algae Based Polymers Blends and Composites written by Khalid Mahmood Zia and published by Elsevier. This book was released on 2017-06-19 with total page 740 pages. Available in PDF, EPUB and Kindle. Book excerpt: Algae Based Polymers, Blends, and Composites: Chemistry, Biotechnology and Material Sciences offers considerable detail on the origin of algae, extraction of useful metabolites and major compounds from algal bio-mass, and the production and future prospects of sustainable polymers derived from algae, blends of algae, and algae based composites. Characterization methods and processing techniques for algae-based polymers and composites are discussed in detail, enabling researchers to apply the latest techniques to their own work. The conversion of bio-mass into high value chemicals, energy, and materials has ample financial and ecological importance, particularly in the era of declining petroleum reserves and global warming. Algae are an important source of biomass since they flourish rapidly and can be cultivated almost everywhere. At present the majority of naturally produced algal biomass is an unused resource and normally is left to decompose. Similarly, the use of this enormous underexploited biomass is mainly limited to food consumption and as bio-fertilizer. However, there is an opportunity here for materials scientists to explore its potential as a feedstock for the production of sustainable materials. - Provides detailed information on the extraction of useful compounds from algal biomass - Highlights the development of a range of polymers, blends, and composites - Includes coverage of characterization and processing techniques, enabling research scientists and engineers to apply the information to their own research and development - Discusses potential applications and future prospects of algae-based biopolymers, giving the latest insight into the future of these sustainable materials

Download or read book Encyclopedia of Plant Viruses and Viroids written by K. Subramanya Sastry and published by Springer. This book was released on 2019-12-18 with total page 2936 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Encyclopedia of Plant Viruses and Viroids provides an up-to-date information on the viruses and viroids infecting all types of cultivated and weed plants at global level; and is unique among plant virology texts as it is organized alphabetically by the genus name of the host plant infected. It allows the reader to readily determine all of the different viruses currently reported naturally infecting the plant genus and species. Information is provided for each virus and viroids on common synonyms, current taxonomic status, geographical distribution, symptoms induced, other known hosts, means of transmission and properties of both the virus particles and the genome. Where ever the same virus is known to infect multiple hosts, host-specific information, biological properties and genome characters are presented under each host affected. The index can be utilized to identify other crops infected by the same virus, showing which other crops might be at risk of infection in the event of introduction of a virus that has not previously reported in an area, or which might serve as potential virus reservoirs for infection of more sensitive or economically important crops than the host in which it is initially identified. The taxonomy and nomenclature of the viruses and viroids are followed based on the current guidelines of the 10th ICTV Report, covering up to 2018 and also about many new viruses and viroids that have been reported but not yet recognized as species by ICTV, have been included in this Encyclopedia. The uniqueness of this Encyclopedia is that all the known viruses and viroids affecting more than 1010 plant species at global level are described and the plant species are arranged in alphabetical order of the scientific name of the plant along the relevant information on 1518 viruses and viroids and is the ready-reckoner of the global plant species and their viruses and viroids for students, scientists, teachers of Plant Pathology& Virology; and also for the crop protection professionals, agricultural policymakers, seed companies and quarantine agencies.

Download or read book Orchids as Aphrodisiac Medicine or Food written by Eng Soon Teoh and published by Springer. This book was released on 2019-07-17 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Did you know that Vanilla was formerly served as aphrodisiac by Cassanova and Madam Pompadour, and Elizabeth I loved its flavor? This is the first book that provides a complete worldwide coverage of orchids being employed as aphrodisiacs, medicine or charms and food. Opening with an in-depth historical account of orchids (orchis Greek testicle), the author describes how the Theory of Signatures influenced ancient herbalists to regard terrestrial orchid tubers as aphrodisiacs. Doctors and apothecaries promoted it during the Renaissance. Usage of orchids in Traditional Chinese Medicine, Indian Ayurvedic Medicine; by Tibetan yogins and Amchi healers for longevity pills, tonics and aphrodisiacs; by Africans to prepare 'health promoting' chikanda or as survival food when lost in the Australian bush are some highlights of the book. Early settlers in America and the East Indies often relied on native remedies and employment of orchids for such needs is described. Also covered are the search for medicinal compounds by scientists, attempts to prove the orchid's efficacy by experiment and the worry of conservationists.

Book excerpt: "César Vallejo is the greatest Catholic poet since Dante—and by Catholic I mean universal."—Thomas Merton, author of The Seven Storey Mountain "An astonishing accomplishment. Eshleman's translation is writhing with energy."—Forrest Gander, author of Eye Against Eye "Vallejo has emerged for us as the greatest of the great South American poets—a crucial figure in the making of the total body of twentieth-century world poetry. In Clayton Eshleman's spectacular translation, now complete, this most tangled and most rewarding of poets comes at us full blast and no holds barred. A tribute to the power of the imagination as it manifests through language in a world where meaning has always to be fought for and, as here, retrieved against the odds."—Jerome Rothenberg, co-editor of Poems for the Millennium "Every great poet should be so lucky as to have a translator as gifted and heroic as Clayton Eshleman, who seems to have gotten inside Vallejo's poems and translated them from the inside out. The result is spectacular, or as one poem says, 'green and happy and dangerous.'"—Ron Padgett, translator of Complete Poems by Blaise Cendrars "César Vallejo was one of the essential poets of the twentieth century, a heartbreaking and groundbreaking writer, and this gathering of the many years of imaginative work by Clayton Eshleman is one of Vallejo's essential locations in the English tongue."—Robert Hass, former Poet Laureate of the United States "This is a crucially important translation of one of the poetic geniuses of the twentieth century." —William Rowe, author of Poets of Contemporary Latin America: History and the Inner Life "Only the dauntless perseverance and the love with which the translator has dedicated so many years of his life to this task can explain why the English version conveys, in all its boldness and vigor, the unmistakable voice of César Vallejo."—Mario Vargas Llosa
