Colloquium on Variation and Evolution in Plants and Microorganisms--Toward a New Synthesis--50 Years After Stebbins


Book Description

Annotation In 1950, Stebbins (d. 2000) published Variation and Evolution in Plants, which extended the synthetic theory of evolution or "the modern synthesis" to plants. These 17 papers are drawn from a National Academy of Sciences colloquium held in January 2000 on the 50th anniversary of the publication of Stebbins' classic. Following a Stebbins appreciation talk (originally slotted for his own words), papers branch into sections on: early evolution and the origin of cells, virus and bacterial models, protoctist models (having to do with RNA editing), population variation, and trends and patterns in plant evolution.

Variation and Evolution in Plants and Microorganisms


Book Description

"The present book is intended as a progress report on [the] synthetic approach to evolution as it applies to the plant kingdom." With this simple statement, G. Ledyard Stebbins formulated the objectives of Variation and Evolution in Plants, published in 1950, setting forth for plants what became known as the "synthetic theory of evolution" or "the modern synthesis." The pervading conceit of the book was the molding of Darwin's evolution by natural selection within the framework of rapidly advancing genetic knowledge. At the time, Variation and Evolution in Plants significantly extended the scope of the science of plants. Plants, with their unique genetic, physiological, and evolutionary features, had all but been left completely out of the synthesis until that point. Fifty years later, the National Academy of Sciences convened a colloquium to update the advances made by Stebbins. This collection of 17 papers marks the 50th anniversary of the publication of Stebbins' classic. Organized into five sections, the book covers: early evolution and the origin of cells, virus and bacterial models, protoctist models, population variation, and trends and patterns in plant evolution.




Understanding Food Insecurity


Book Description

This book provides a comprehensive overview of key aspects of food insecurity, including definitional and conceptual issues, information systems and data sources, indicators, and policies. The aim is to equip readers with a sound understanding of the subject that will assist in the recognition of food insecurity and the design of suitable responses. The early chapters discuss the evolution and limitations of the concept and provide a set of conceptual frameworks for the analysis of food security. Systems used to collect data and their evolution over time are then explained, and the most commonly adopted indicators for monitoring food security are presented. Approaches to food security are then thoroughly reviewed decade by decade. Specific attention is paid to the food insecurity challenge in the new millennium, focusing particularly on recent food crises and institutional and policy-related consequences. Finally, the specific terminology of food aid and assistance is examined, with discussion of the instruments recently adopted in the food aid system. This book will be an informative and stimulating resource for both students and professionals.
