Download or read book Vectors of Plant Pathogens written by Kerry F. Harris and published by Academic Press. This book was released on 2013-10-02 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vectors of Plant Pathogens is a collection of papers that discusses the interrelationship of plant pathogens with their vectors. This collection deals with the numerous vector groups associated with plant pathogens. One paper describes the biology, feeding behavior and distribution of aphids, leafhoppers, plant hoppers, mealy bugs, whiteflies, psyllids, membracids. Another paper addresses the virus transmission characteristics of the mealy bugs during preliminary fasting or feeding, acquisition access time, post-acquisition fasting or feeding, and the inoculation access time. Other papers also discuss the involvement of insects in transmitting bacterial and fungal pathogens; the authors list unresolved issues such as the role of insects in overwintering of bacterial pathogens or the association of the fungus with a particular vector. One author describes some suspected fungi transmission such as the pea stem necrosis virus, red clover necrotic mosaic virus, and the tomato bushy stunt virus. Another paper examines the fate of plant viruses in mite vectors and convectors particularly the viruses found in wheat, barley, or brome grass. Agriculturists, botanists, and researchers in the field of botany, conservation, and plant genealogy will find this book useful.

Download or read book Advances in Archaeological Method and Theory written by Michael B Schiffer and published by Academic Press. This book was released on 2014-06-30 with total page 479 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in Archaeological Method and Theory, Volume 9 is a collection of papers that describes protohuman culture, pastoralism, artifact classification, and the use of materials science techniques to study the construction of pottery. Some papers discuss contingency tables, geophysical methods of archaeological site surveying, and predictive models for archaeological resource location. One paper reviews the methodological and theoretical advances in the archaeological studies of human origins, particularly covering the Plio-Pleistocene period. Another paper explains the historic and prehistoric development of pastoralism through archaeological investigation. One paper traces the three phases of artifact classification, each being a representation of a different attitude and approach. Another paper evaluates pottery artifacts using a number of basic materials-science concepts and analytic approaches, toward the study of their mechanical strength; and also reviews their use in archaeological studies of pottery production and organization. To investigate archaeological intrasites, the archaeologist can use different specialized methods such as seismic, electromagnetic, resistivity, magnetometry, and radar. Another paper describes various empiric correlative models for locational prediction developed in both contexts of cultural resource management and academic research. Sociologists, anthropologist, ethnographers, museum curators, professional or amateur archaeologists will find the collection immensely valuable.

Book excerpt: Originally published in 1990 Tropical Resources presents in-depth coverage of the extremely diverse tropical environments, the resources to be found within the region and their production, and ecological management. The book discusses economic geography and ways of utilizing available resources, including those of tropical forests, wildlife, tidal wetlands and the sea. The book also include chapters on the development and land use of protected areas, the ecological aspects of pasture resources; and the impacts of economic development and population damage. In addition, studies are offered on tropical soils, including their distribution properties and management and the ecological processes at work in tropical forests. For geographers, economists and policymakers, the book provides a wealth of information on tropical resources and their potential development.
