Viral Ecology defines and explains the ecology of viruses by examining their interactions with their hosting species, including the types of transmission cycles that have evolved, encompassing principal and alternate hosts, vehicles, and vectors. It examines virology from an organismal biology approach, focusing on the concept that viral infections represent areas of overlap in the ecology of viruses, their hosts, and their vectors. Abstract. In recent decades ecology has become one of the dominant themes of the biological sciences. However, this has not always been so as the subject emerged from the specialiCited by: The genomes of viruses comprise a basic unit of replication-associated protein(s) and coat proteins to which are added modules including those that facilitate virus movement within the plant and between plants and defense against the host defense systems. An appreciation of the risks caused by emergent plant viruses is critical in tropical areas that rely heavily on agriculture for subsistence and rural livelihood. Molecular ecology, within 10 years, has unraveled the factors responsible for the emergence of several of the economically most important tropical plant viruses: (RYMV), Cassava mosaic geminiviruses (CMGs), Cited by:
The numerous photographs and line illustrations, and the large reference section, qualify this book as a field guide and reference for workers in tropical and temperate research. The fascinating ecology and natural history of these bees will also provide absorbing reading for other ecologists and naturalists. This book was first published in Reviews: 1. As plants make up over 80% of the biomass on Earth, plant viruses likely have a larger impact on ecosystem stability and function than viruses of other by: 9. Plant viruses follow one or more of the pathways shown when they spread between plants. A virus may be retained within a crop cultivar either by vegetative propagation (pathosystem 1; see) or by pollen or seed transmission (pathosystem 2); it may spread by mechanical transmission (pathosystem 3). Since the publication of the first edition of this book ten years ago, international research into the physiological ecology of plants in the tropics has increased enormously in quantity and quality. This brand new edition brings the story right up to date. New approaches have been developed in remote sensing while at the other end of the scale Format: Hardcover.
The current prominence and status of ecology is reflected in the series of Inaugural Lectures of which this is a part. It is concerned with the ecology of tropical plant viruses and Professor Cheke also adopted an ecological approach in his presentation on river : J. Michael Thresh. To cover these recent findings, a new text book in plant virology is most welcome. This book is a translated and updated version of a French book from (Principes de Virologie Végétale, INRA, Paris). It describes in 15 chapters different aspects of plant virology, comprising the three sections: the virus, the cell and the plant; the virus Author: Anders Kvarnheden. Ecology of Plants in the Tropics Daniel H. Janzen. 1 Vegetative Biology Introduction The vegetative parts of a tropical plant, just as with a tem- perate zone plant, are primarily adaptive in the context of gathering, storage, and manipulation of resources. These activities are carried outFile Size: KB. The epidemiology of plant virus diseases is concerned to the cyclical development of diseases within the plant populations in time and space. Aspects like disease gradients, progress curves, spatial dynamics and meta-populations, systems analysis and simulation models are also discussed in by: 1.
