Book Description
IAU Symposium 265 presents a unified picture of nucleosynthesis, the production of chemical elements over cosmic time. It explains how this chemical evolution links together the early Universe of the first stars, through the formation of galaxies and their diverse populations of stars, to a Universe of heavy-element rich stars and planets. The first generation of massive stars that drove reionization left their chemical signatures imprinted in the oldest low-mass stars, which we observe today. Chemical evolution is a broad, diverse and rapidly evolving field, due to the ever-expanding capabilities delivered by new arrays of instruments on large telescopes, together with significant advances in modelling and increasing access to large and accurate nuclear, atomic, and molecular databases. Written for researchers and graduate students, the topics covered in this volume provide a comprehensive overview of the scientific progress achieved in recent years.

Book Description
The Transactions XXVIIA Reports on Astronomy 2006-2009 provides a comprehensive and authoritative review of what has been achieved in astronomy during the years 2006 to 2009. These insightful and up-to-date reviews have been written by the presidents and chairpersons of the IAU scientific bodies: the Divisions, the Commissions, and the Working Groups. Topics covered in this wide-ranging volume include: fundamental astronomy; the Sun and heliosphere; planetary sciences; stars; variable stars; interstellar matter; the Galactic system; galaxies and the Universe; optical and infrared techniques; radio astronomy; space and high-energy astrophysics; and other IAU activities. The reviews have been written at a level suitable for colleagues in the same fields, but will also be useful for students and researchers wishing to gain an overview of astronomical fields beyond their own research area.

Book Description
Our knowledge of the origin, evolution, nature, and distribution of organic matter in space has undergone a revolution in recent years. Insights into various aspects of this material can be found using a variety of different technical approaches. These range from telescopic measurements by observational astronomers over a wide range of wavelengths, to laboratory experiments and simulations by chemists, physicists, and spectroscopists, and analyses of actual extraterrestrial materials. IAU Symposium 251 brought together expertise of scientists from different disciplines, including observational astronomers, laboratory spectroscopists, and solar system scientists, to provide a synthesis of our current understanding of these organics and to identify areas in which additional work and new ideas are required to further our understanding.

Book Description
IAU Symposium 268 presents an overview of the most recent observational and theoretical research on the formation and evolution of light elements in the Universe: H, He, Li, Be, B, and their isotopes. Astrophysicists from a variety of subfields discuss recent developments that will improve our understanding of the light elements and provide important clues to stellar and galactic evolution, Big Bang nucleosynthesis, and cosmology. Striking observational progress has been achieved recently through the advent of next generation ground- and space-based telescopes, such as the cosmic microwave background experiments that allow the accurate determination of the baryon density of the Universe. New theoretical breakthroughs in describing stellar interiors and the chemical evolution of complex systems and the remaining challenges in this field are also addressed. This critical review is a useful resource for all those interested in the chemical evolution of the Universe.

Book Description
Astrochemistry, the study of molecules and their chemistry in astrophysical objects throughout the Universe, is experiencing a true golden age. Astronomical observations of molecules are crucial in contributing to our understanding of the physical conditions in many different astrophysical environments, from the Solar System and extrasolar planets to stars, interstellar clouds and galaxies. Concurrently, laboratory experiments and theoretical studies can provide basic information about the often exotic chemical processes taking place in the Universe. IAU Symposium 280 contains outstanding reviews on the advances in observational, laboratory, theoretical and modelling studies, carried out by leading scientists worldwide. This volume provides researchers and graduate students with an indispensable account of the current state of astrochemistry, its recent successes and the immense possibilities of this fascinating field for future growth.

Carbon Dioxide and Environmental Stress

Book Description
This book focuses on the interactive effects of environmental stresses with plant and ecosystem functions, especially with respect to changes in the abundance of carbon dioxide. The interaction of stresses with elevated carbon dioxide are presented from the cellular through whole plant ecosystem level. The book carefully considers not only the responses of the above-ground portion of the plant, but also emphasizes the critical role of below-ground (rhizosphere) components (e.g., roots, microbes, soil) in determining the nature and magnitude of these interactions. * Will rising CO2 alter the importance of environmental stress in natural and agricultural ecosystems?* Will environmental stress on plants reduce their capacity to remove CO2 from the atmosphere?* Are some stresses more important than others as we concern ourselves with global change?* Can we develop predictive models useful for scientists and policy-makers?* Where should future research efforts be focused?

Book Description
This book has been developed to provide a detailed discussion of probiotics, which have been evaluated for use predominantly in fish and shellfish aquaculture. This book highlights strengths and weaknesses in knowledge and discusses gaps that need to be addressed. There has been a great deal of research concerning the use of probiotics in aquaculture. To date, a wide range of Gram-positive and Gram-negative bacteria and some eukaryotes, i.e. yeasts and unicellular algae, has been reported to be beneficial to aquatic hosts. Following oral uptake, benefit includes improved growth performance and protection against many bacteria and some parasitic diseases. This book will be suitable for scientists, veterinarians, professionals, and senior students involved in aquaculture.
