Download or read book Nematode Vectors of Plant Viruses written by Charles E. Taylor and published by . This book was released on 1997 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Viruses transmitted by nematodes are responsible for many economically important diseases of crops. Thus, when in the late 1950s, this mode of disease propagation was demonstrated by proof of the transmission of grapevine fanleaf disease by Xiphinema index, it marked the start of a significant and fruitful period of research. Since that time, however, numerous reviews have been published on different aspects of nematode transmission of plant viruses and the nematode transmitted viruses themselves. However, until now there has been a lack of any source which draws all of this research together. This book fills this need by providing a valuable overview of the last forty years of research into the transmission of viruses by nematodes, as well as setting the agenda for future investigations. This book is an important resource for all crop protectionists, nematologists, and plant virologists.

Download or read book Phytoplasmas Plant Pathogenic Bacteria I written by G.P. Rao and published by Springer. This book was released on 2018-08-02 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phytoplasma-associated diseases are a major limiting factor to quality and productivity of many ornamentals, horticultural and other economically important agriculture crops worldwide. Annual losses due to phytoplasma diseases in many crops vary, but under the pathogen favorable conditions they always lead to disastrous consequences to farming community. As there is no effective cure for phytoplasma diseases, the management options emphasize on their exclusion, minimizing their spread by insect vectors and propagation materials and on development of host plant resistance. The phytoplasma associated plant diseases have a history of more than 50 years. Phytoplasmas have undoubtedly infected plants and cause diseases for centuries before they are described and proven to be the causal agents. But important progress related to identification of phytoplasmas only began after 1980’s. Phytoplasmas have emerged as the most serious constraints in the production of several crops all around the world during last four decades. Phytoplasmas constitute a major limiting factor to quality and productivity of cereals, horticultural, ornamentals and many other economically important crops all over the world. Annual losses due to phytoplasma diseases may vary, but under the pathogen favorable condition, phytoplasma disease may lead to disastrous consequences for farming and industry community. The scientific literature concerning phytoplasma occurrence, characterization, diagnosis, detection, and management is growing at a fast pace. Significant advancement in the last decades on diagnostic, biological and molecular properties, epidemiology, host-pathogen-insect interactions as well as management of phytoplasmas has been made. Till date, no authentic compilation is available to know the progress of phytoplasmas characterization major crops all over the world. The planned book will compile all the updated information available information on phytoplasmas by distinguished experts in the form of edited book entitled “Characterization and epidemiology of phytoplasma associated diseases”. The book covers recent and update information on emerging and re-emerging phytoplasma diseases affecting important crops in tropics and subtropics. It provides comprehensive information on disease distribution, occurrence, and identification of the phytoplasmas including the recent approaches for diagnostics, transmission, and information about losses and geographical distribution along with and management aspects. This volume contains 11-12 chapters contributed by the experienced and recognized experts working on different group of phytoplasmas affecting major crops all over the world. The information on various topics is at advanced as well as comprehensive level and provides the period wise developments of phytoplasma research. The book covers major chapters on an up to date progress of phytoplasma research, and then phytoplasma diseases associated with vegetable, pulse, oils crops, cereals, sugar crops, fruit crops, ornamentals, medicinal plants, palms species, forest tress and weeds. We have covered historical background, geographical distribution, identification and characterization, genetic diversity, host pathogen interaction and management aspects of important phytoplasma diseases infecting our major agricultural crops. The information on various topics is advanced as well as comprehensive, and provides thought provoking ideas for planning novel research ideas for future. This book will be useful to everyone interested in mollicutes, phytoplasma, spiroplasmas, plant pathology, disease control and plant biology and serve as an exhaustive and up-to-date compendium of references on various aspects of different groups of phytoplasmas affecting important crops worldwide.

Download or read book Multitrophic Level Interactions written by Teja Tscharntke and published by Cambridge University Press. This book was released on 2002-03-21 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: The multitrophic level approach to ecology addresses the complexity of food webs much more realistically than the traditional focus on simple systems and interactions. Only in the last few decades have ecologists become interested in the nature of more complex systems including tritrophic interactions between plants, herbivores and natural enemies. Plants may directly influence the behaviour of their herbivores' natural enemies, ecological interactions between two species are often indirectly mediated by a third species, landscape structure directly affects local tritrophic interactions and below-ground food webs are vital to above-ground organisms. The relative importance of top-down effects (control by predators) and bottom-up effects (control by resources) must also be determined. These interactions are explored in this exciting volume by expert researchers from a variety of ecological fields. This book provides a much-needed synthesis of multitrophic level interactions and serves as a guide for future research for ecologists of all descriptions.

Download or read book The Runes of Evolution written by Simon Conway Morris and published by Templeton Foundation Press. This book was released on 2015-06-30 with total page 525 pages. Available in PDF, EPUB and Kindle. Book excerpt: How did human beings acquire imaginations that can conjure up untrue possibilities? How did the Universe become self-aware? In The Runes of Evolution, Simon Conway Morris revitalizes the study of evolution from the perspective of convergence, providing us with compelling new evidence to support the mounting scientific view that the history of life is far more predictable than once thought. A leading evolutionary biologist at the University of Cambridge, Conway Morris came into international prominence for his work on the Cambrian explosion (especially fossils of the Burgess Shale) and evolutionary convergence, which is the process whereby organisms not closely related (not monophyletic), independently evolve similar traits as a result of having to adapt to similar environments or ecological niches. In The Runes of Evolution, he illustrates how the ubiquity of convergence hints at an underlying framework whereby many outcomes, not least brains and intelligence, are virtually guaranteed on any Earth-like planet. Conway Morris also emphasizes how much of the complexity of advanced biological systems is inherent in microbial forms. By casting a wider net, The Runes of Evolution explores many neglected evolutionary questions. Some are remarkably general. Why, for example, are convergences such as parasitism, carnivory, and nitrogen fixation in plants concentrated in particular taxonomic hot spots? Why do certain groups have a particular propensity to evolve toward particular states? Some questions lead to unexpected evolutionary insights: If bees sleep (as they do), do they dream? Why is that insect copulating with an orchid? Why have sponges evolved a system of fiber optics? What do mantis shrimps and submarines have in common? If dinosaurs had not gone extinct what would have happened next? Will a saber-toothed cat ever re-evolve? Cona Morris observes: “Even amongst the mammals, let alone the entire tree of life, humans represent one minute twig of a vast (and largely fossilized) arborescence. Every living species is a linear descendant of an immense string of now-vanished ancestors, but evolution itself is the very reverse of linear. Rather it is endlessly exploratory, probing the vast spaces of biological hyperspace. Indeed this book is a celebration of how our world is (and was) populated by a riot of forms, a coruscating tapestry of life.” The Runes of Evolution is the most definitive synthesis of evolutionary convergence to be published to date.

Download or read book Saproxylic Insects written by Michael D. Ulyshen and published by Springer. This book was released on 2018-05-21 with total page 896 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume offers extensive information on insect life in dying and dead wood. Written and reviewed by leading experts from around the world, the twenty-five chapters included here provide the most global coverage possible and specifically address less-studied taxa and topics. An overarching goal of this work is to unite literature that has become fragmented along taxonomic and geographic lines. A particular effort was made to recognize the dominant roles that social insects (e.g., termites, ants and passalid beetles) play in saproxylic assemblages in many parts of the world without overlooking the non-social members of these communities. The book is divided into four parts: · Part I “Diversity” includes chapters addressing the major orders of saproxylic insects (Coleoptera, Diptera, Hymenoptera, Hemiptera, Lepidoptera and Blattodea), broadly organized in decreasing order of estimated global saproxylic diversity. In addition to order-level treatments, some chapters in this part discuss groups of particular interest, including pollinators, hymenopteran parasitoids, ants, stag and passalid beetles, and wood-feeding termites. · Part II “Ecology” discusses insect-fungal and insect-insect interactions, nutritional ecology, dispersal, seasonality, and vertical stratification. · Part III “Conservation” focuses on the importance of primary forests for saproxylic insects, offers recommendations for conserving these organisms in managed forests, discusses the relationships between saproxylic insects and fire, and addresses the value of tree hollows and highly-decomposed wood for saproxylic insects. Utilization of non-native wood by saproxylic insects and the suitability of urban environments for these organisms are also covered. · Lastly, Part IV “Methodological Advancements” highlights molecular tools for assessing saproxylic diversity. The book offers an accessible and insightful resource for natural historians of all kinds and will especially appeal to entomologists, ecologists, conservationists and foresters.
