Book Description
Small-scale fisheries are a major source of food and employment around the world. Yet, many small-scale fishers work in conditions that are neither safe nor secure. Millions of them are poor, and often they are socially and politically marginalized. Macro-economic and institutional mechanisms are essential to address these poverty and vulnerability problems; however, interventions at the local community level are also necessary. This requires deep understanding of what poverty means to the fishers, their families and communities; how they cope with it; and the challenges they face to increase resiliency and improve their lives for the better. This book provides a global perspective, situating small-scale fisheries within the broad academic discourse on poverty, fisheries management and development. In-depth case studies from fifteen countries in Latin America, Europe, South and Southeast Asia, and sub-Saharan Africa, demonstrate the enormously complex ecological, economic, social, cultural and political contexts of this sector. Conclusions for policy-making, formulated as a joint statement by the authors, argue that fisheries development, poverty alleviation, and resource management must be integrated within a comprehensive governance approach that also looks beyond fisheries. The scientific editors, Svein Jentoft and Arne Eide, are both with the Norwegian College of Fishery Science, Faculty of Biosciences, Fisheries and Economics, University of Tromsø, Norway.

Book Description
Alternative methods of disease control such as natural products and compounds derived from biological origins, provide an effective alternate to the use of chemical products or a means to minimize their use. It is imperative now to look for such sustainable crop disease management approaches, that include routine and alternative methods. Natural products for sustainable crop disease management is an effort in this direction, and deals with immediate concerns in the field of natural and alternative products for disease control, apart from using biocontrol organisms. This book presents up-to-date information on natural products and compounds derived from biological origins and thoroughly discusses their applicability, field use and prospects for adoption under different cropping conditions. This book also validates disease management strategies.

Book Description
Geminivirus: Detection, Diagnosis and Management focuses on the latest techniques for managing diseases caused by these circular, single-stranded (ss) DNA genomes. The most significant impact of plant diseases in host populations is often caused by emerging diseases, whose incidence in a plant host is increasing as a result of long-term changes in their underlying epidemiology. Genetic changes in pathogen and host populations, as well as changes in host ecology and environment, are major factors contributing to disease emergence. Understanding plant virus evolution is crucial for modeling the within-host and between-host dynamics and genetics of virus populations. The book presents a comprehensive review of how these viruses develop, including contributing factors such as population bottlenecks during cell-to-cell movement, systemic colonization, or between-host transmission by different procedures. Presented in five sections—Detection and Diagnosis, Emergence and Diversity, Vector and Transmission, Virus–Host Interaction, and Disease Management, the book includes host range determinant and virulence factors involved in pathogenesis, virus–vector interactions during acquisition, retention, and transmission and evaluating management strategies to control Geminivirus. The book is an essential reference for students and researchers interested in plant virology, particularly begomoviruses, geminiviruses, and vector transmission biology. - Introduces identification and characterization of geminiviruses that infect agricultural crops, their wild relatives, and weed hosts - Discusses recombination and reassortment mechanisms influencing viral genetic diversity, virulence, and vector transmission - Explores the origin, evolution, and bottlenecks of Geminiviruses - Introduces identification and characterization of geminiviruses that infect agricultural crops, their wild relatives, and weed hosts - Discusses recombination and reassortment mechanisms influencing viral genetic diversity, virulence, and vector transmission - Explores the origin, evolution, and bottlenecks of Geminiviruses

Book Description
The Mosaic of Autoimmunity: The Novel Factors of Autoimmune Diseases describes the multifactorial origin and diversity of expression of autoimmune diseases in humans. The term implies that different combinations of factors in autoimmunity produce varying and unique clinical pictures in a wide spectrum of autoimmune diseases. Most of the factors involved in autoimmunity can be categorized into four groups: genetic, immune defects, hormonal and environmental factors. In this book, the environmental factors are reviewed, including infectious agents, vaccines as triggers of autoimmunity, smoking and its relationship with rheumatoid arthritis, systemic lupus erythematosus, thyroid disease, multiple sclerosis and inflammatory bowel diseases. An entirely new syndrome, the autoimmune/inflammatory syndrome induced by adjuvants (ASIA), is also included, along with other diseases that are now recognized as having an autoimmune etiopathogenesis. Highlights the concept of the mosaic of autoimmune manifestations Includes new visions on unsuspected molecules Provides updated knowledge to physicians helping patients with autoimmune diseases Presents thorough, up-to-date information on specific diseases, along with clinical applications

Book Description
Healthy seeds and propagules are the basic requirement for producing good grains, fruits and vegetables needed for human survival and perpetuation. Dispersal of microbial plant pathogens via seeds and propagules has assumed more importance than other modes of dispersal, as infected seeds and propagules have the potential to become the primary sources of carrying pathogen inoculum for subsequent crops. Several diseases transmitted through seeds and propagules have been shown to have the potential to damage economies as a result of huge quantitative and qualitative losses in numerous crops. Hence, it is essential to rapidly detect, identify and differentiate the microbial plant pathogens present in seeds and propagules precisely and reliably, using sensitive techniques. Microbial Plant Pathogens: Detection and Management in Seeds and Propagules provides a comprehensive resource on seed-borne and propagule-borne pathogens. Information on the biology of microbial pathogens, including genetic diversity, infection process and survival mechanisms of pathogens and epidemiology of diseases caused by them, are discussed critically and in detail to highlight weak links in the life cycles of the pathogens. Development of effective disease management systems, based on the principles of exclusion and eradication of pathogens and immunization of crop plants to enhance the levels of resistance of cultivars to diseases, has been effective to keep the pathogens at bay. The need for production of disease-free seeds/propagules has been emphasized to prevent the carryover of the inoculum to the next crop or introduction of the pathogens to other locations. Effectiveness of adopting simple cultural practices and development of cultivars resistant to diseases through traditional breeding methods or biotechnological approach have resulted in reducing the pathogen inoculum and disease incidence. Although application of different chemicals may reduce the disease incidence effectively, biological management of crop diseases, employing potential biological control agents have to be preferred to preserve the agroecosystems. Greater efforts have to be made to integrate compatible strategies to enhance the effectiveness of diseases management systems. Protocols appended at the end of relevant chapters form a unique feature of this book to enable the researchers to fine-tune their projects. This 2 volume set provides comprehensive and updated information about the economically-important groups of microbial plant pathogens carried by seed and propagules. Graduate students, researchers and teachers of plant pathology, plant protection, microbiology, plant breeding and genetics, agriculture and horticulture, as well as certification and quarantine personnel will find the information presented in this book useful.

Book Description
The history of pathogens and vectors, unique symptoms of diseases and economic importance of important viral diseases have been dealt with in the introductory chapter of this book. While highlighting the role of arthropods, nematodes, and fungi; other agents of the spread of plant pathogens have also been included. Important aspects of insect vectors with direct bearing on transmission, i.e. vector identification, biology, feeding apparatus, and mechanism of spread including control of pathogens through vectors are covered comprehensively. As aphids and other hemipterous insects are major insect vectors, the book stresses on this order. There is a focus on the transmission of determinants under different categories of the transmission mechanism. The transmission determinant paradigm comprising coat protein and helper component has been expounded with recent cases. A brief description of new diseases at least one from each genus of plant viruses has been included in this compendium to elucidate the interaction of vector and virus. Phytoplasmal etiology of pathogens has been detailed separately on account of their importance. The transmission of plant viruses through insects with biting and chewing type of mouth parts has been discussed in detail as separate chapter. The latest research in the field of mites, nematodes, and fungi as vectors of plant viruses has been included. How the phytotoxemia is different from other crop disorders, has been critically explained with support from suitable and common examples of crop disorders. The book also highlights the effects of plant viruses on their vectors. An account of classification of plant viruses has also been given for better understanding of subject matter. Likewise, the information on the electron microscope along with its use has been included so as to define the procedure of examining sub-microscopic entities. The latest developments in the management of plant pathogens through vector management have been discussed with special reference to the use of biotechnology, crop protection, and plant resistance. The book will be of value to the teachers and to researchers. It will also be useful for extension workers in managing crop disorders. Students and researchers of entomology, plant pathology, plant protection and virology disciplines will obtain the latest in the field, through this book.
