Book Description
Through Katherine MacLean's artistry and imagination you'll soar through space, you'll touch the stars, you'll bask in the glow of other suns...and you will be one with - The long-legged lawyer who suspected that he was a Martian - The boy who became all he characters in his make-believe games - The sewing-circle ladies who took over the world - The alien spacemen adrift in a raindrop - The woman who discovered the terrible secret of immortality There are other stories in this remarkable collection, but merely to describe them might give away their plots, and that is a dastardly crime punishable by indefinite exile on mysterious, fog-shrouded Planet X!

Book Description
This book adopts an experimental approach to understanding the mechanisms of evolution and the nature of evolutionary processes, with examples drawn from microbial, plant and animal systems. It incorporates insights from remarkable recent advances in theoretical modelling, and the fields of molecular genetics and environmental genomics. Adaptation is caused by selection continually winnowing the genetic variation created by mutation. In the last decade, our knowledge of how selection operates on populations in the field and in the laboratory has increased enormously, and the principal aim of this book is to provide an up-to-date account of selection as the principal agent of evolution. In the classical Fisherian model, weak selection acting on many genes of small effect over long periods of time is responsible for driving slow and gradual change. However, it is now clear that adaptation in laboratory populations often involves strong selection acting on a few genes of large effect, while in the wild selection is often strong and highly variable in space and time. Indeed these results are changing our perception of how evolutionary change takes place. This book summarizes our current understanding of the causes and consequences of selection, with an emphasis on quantitative and experimental studies. It includes the latest research into experimental evolution, natural selection in the wild, artificial selection, selfish genetic elements, selection in social contexts, sexual selection, and speciation.

Book Description
The significance of Biotechnology in the field of fisheries and aquaculture is investigated in view of distributed writing. Aquaculture is the cultivating and farming of oceanic life forms and as it is the quickest developing sustenance area on the planet with its expanding part for economy and safe nourishment system of nations. Because of the proceeding with exhaustion of the fish stocks, cultivating of amphibian life forms, for example, angle, shellfish, mollusks and sea-going plants, is presently a considerable worldwide industry providing a critical extent of the oceanic items devoured. Deficiency in nourishment supply and high costs are the conceivable vital dangers later on, and sea-going items are the important wellsprings of protein and fundamental supplement segments for worldwide sustenance security and wiping out ailing health. Aquaculture additionally assumes an imperative part in country economies through the making of new occupations. In these cases, aquaculture yields should be improved a few overlay to meet the rising requests for angle and other sea-going items in coming years. Biotechnology choices appear to be great potential for expanding water social efficiency, nourishment security and ecological quality around the world. Therefore, this book talked about the significance of biotechnology in aquaculture, and arrangements for the ecologically stable utilize and administration of water social biotechnology in feasible improvement of fisheries.

Book Description
The production of doubled haploids has become a necessary tool in advanced plant breeding institutes and commercial companies for breeding many crop species. However, the development of new, more efficient and cheaper large scale production protocols has meant that doubled haploids are also recently being applied in less advanced breeding programmes. This Manual was prepared to stimulate the wider use of this technology for speeding and opening up new breeding possibilities for many crops including some woody tree species. Since the construction of genetic maps using molecular markers requires the development of segregating doubled haploid populations in numerous crop species, we hope that this Manual will also help molecular biologists in establishing such mapping populations. For many years, both the Food and Agriculture Organization of the United Nations (FAO) and the International Atomic Energy Agency (IAEA) have supported and coordinated research that focuses on development of more efficient doubled haploid production methods and their applications in breeding of new varieties and basic research through their Plant Breeding and Genetics Section of the Joint F AO/IAEA Division of Nuclear Techniques in Food and Agriculture. The first F AO/IAEA scientific network (Coordinated Research Programme - CRP) dealing with doubled haploids was initiated by the Plant Breeding and Genetics Section in 1986.

Book Description
This volume and its companion, Volume 351, are specifically designed to meet the needs of graduate students and postdoctoral students as well as researchers, by providing all the up-to-date methods necessary to study genes in yeast. Procedures are included that enable newcomers to set up a yeast laboratory and to master basic manipulations. Relevant background and reference information given for procedures can be used as a guide to developing protocols in a number of disciplines. Specific topics addressed in this book include basic techniques, making mutants, genomics, and proteomics.
