All life is chemical. That fact underpins the developing field of ecological stoichiometry, the study of the balance of chemical elements in ecological interactions. This long-awaited book brings this field into its own as a unifying force in ecology and evolution. Synthesizing a wide range of knowledge, Robert Sterner and Jim Elser show how an understanding of the biochemical deployment of elements in organisms from microbes to metazoa provides the key to making sense of both aquatic and terrestrial ecosystems. After summarizing the chemistry of elements and their relative abundance in Earth's environment, the authors proceed along a line of increasing complexity and scale from molecules to cells, individuals, populations, communities, and ecosystems. The book examines fundamental chemical constraints on ecological phenomena such as competition, herbivory, symbiosis, energy flow in food webs, and organic matter sequestration. In accessible prose and with clear mathematical models, the authors show how ecological stoichiometry can illuminate diverse fields of study, from metabolism to global change. Set to be a classic in the field, Ecological Stoichiometry is an indispensable resource for researchers, instructors, and students of ecology, evolution, physiology, and biogeochemistry. From the foreword by Peter Vitousek: ? "[T]his book represents a significant milestone in the history of ecology. . . . Love it or argue with it--and I do both--most ecologists will be influenced by the framework developed in this book. . . . There are points to question here, and many more to test . . . And if we are both lucky and good, this questioning and testing will advance our field beyond the level achieved in this book. I can't wait to get on with it."

This book collates a wide spectrum of topics relevant to contemporary research achievement in sustainable utilization of plant genetic resources and conservation of plant genetic diversity within the framework of different crop systems. It introduces the status of crop genetic diversity and provides prospects for conservation of crop genetic diversity for sustainable agriculture. Plant genetic diversity is crucial for food security and agro-ecosystem maintenance paving ways to achieve sustainable agriculture development. This necessitates, consciously and judiciously, the conservation of all existing plant genetic resources for sustainable use in a variety of applications for human welfare. The wild and traditional landraces have generated an increased interest as a repertoire of valuable traits for breeding and improvement of cultivated germplasm. Internationally, concerted actions and policies toward for the conservation and management of plant genetic diversity are mounting, from the organization levels to national policies as deemed appropriate for the sustainable development goals. This needs an understanding of genetic diversity of different crops, ecological drivers and the structural changes within genetic diversity due to climate change. It is also equally important to evolve knowledge on what, how and where to conserve the existing plant genetic resources for present and future use. Assessment of the genetic diversity presents in a wild and traditional agro-ecosystem is another step towards effective utilization. In the past few years, advanced breeding tools have been developed which have offered great promise for efficient modification of targeted traits. This book consolidates current knowledge in the above core areas of plant genetic diversity and conservation. It is an essential reference for professionals, researchers, policy makers and commercial entrepreneurs concerned with plant genetic diversity and breeding to achieve enhanced agricultural productivity and sustainability of food resources to ensure food security. The book is also invaluable for graduate students involved in agriculture research. .

Microbial Symbionts: Functions and Molecular Interactions on Host focuses on microbial symbionts of plants, animals, insects and molecular methods in the identification of microbial symbionts. The book describes the molecular mechanism and interactions of symbiosis of microbiome in plants, animals and humans. It brings the latest techniques for identification, localization and functional characterization of host-associated microbes and explains the role/importance of microbial symbionts. This comprehensive reference covers a wide range of symbiotic microorganisms used for basic and advanced techniques associated with the isolation, characterization and identification of microbial symbiotic microorganisms and their functions and molecular interactions on the host. The book will also helps users plan and execute experiments with appropriate knowledge rather than experimental trial and error in a wide range of disciplines, including Microbiology, Biotechnology, Botany and Zoology.
