Book Synopsis Transitions Between Sexual Systems by : Janet L. Leonard
Download or read book Transitions Between Sexual Systems written by Janet L. Leonard and published by Springer. This book was released on 2019-05-21 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on explaining the distribution of sexual systems (simultaneous hermaphroditism, sequential hermaphroditism, environmental sex determination,dioecy, androdioecy, etc.) among taxa, which remains a major challenge in evolutionary biology. Although significant advances have been made for angiosperms, there is not yet a theory that predicts the sexual system for the majority of animal taxa, and other taxa of plants also remain poorly understood. The problem, particularly for animals, is that sexual systems can be very conservative, with whole phyla and classes being characterized by a single sexual system; for example essentially the whole phylum Platyhelminthes is simultaneously hermaphroditic, whereas the Insecta (Hexapoda) and the Tetrapoda among the vertebrates, are exclusively dioecious. Sex allocation theory on the other hand, suggests that sexual systems should be highly responsive to evolution, changing with population density, life span, patterns of resource availability, etc. The book provides an overview of the topic and then presents a series of chapters, each dealing with a taxon with substantial lability in sexual system in order to identify the factors associated with changes in sexual system in each case. By doing so, the authors reveal factors that have not been considered in formal theory but seem to have a major impact on transitions between sexual systems. This book appeals to a wide readership in fields from zoology and evolutionary biology to botany.

Book Synopsis Strontium Contamination in the Environment by : Pankaj Pathak
Download or read book Strontium Contamination in the Environment written by Pankaj Pathak and published by Springer. This book was released on 2019-06-04 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an authoritative review of the origin and extraction of strontium and its impact on the environment. It also presents the latest strontium decontamination and remediation strategies. Around the globe, nuclear power is being recognized as a major source of energy and is expected to play a crucial role in meeting the energy requirements of present day society. However, the pros and cons have to be considered, and the safe disposal of large amounts of radionuclide wastes is becoming a matter of great concern. These wastes encompass contaminants such as heavy metals and toxic substances, which may exist in solid, liquid or gaseous forms or a combination of these, and as such, their disposal requires particular attention. The book focuses on 90Sr, which is a predominant isotope of strontium and considered an intermediate level radioactive waste with a half-life of 28.8 years, average biological half-life of 18 years and 546 KeV decay energy. Written by expert contributors, it addresses occurrence, detection and extraction of strontium, the chemical and nuclear properties of strontium isotopes, the fate and migration of strontium in soil, its bioaccumulation, and its associated health impact, mechanistic toxicity response as well as related regulation and remediation. It appeals to scholars, scientists and environmental managers working with strontium contamination in the environment and its consequences.
Book Synopsis Transgenic Plants by : Jim M. Dunwell

Book excerpt: In 2010 the global area of transgenic crops reached 148 million hectares, an 87-fold increase since 1996, making it the most rapidly adopted technology in the history of modern agriculture. In Transgenic Plants: Methods and Protocols, Second Edition expert researchers in the field provide key techniques to investigate production and analysis of transgenic plants. Focusing on selection and detection methods, transformation technology, gene targeting, silencing and directed mutation, metabolic engineering and pharming, the book encompasses protocols relating to major crops and model plants being used for genomic analysis. Written in the highly successful Methods in Molecular BiologyTM series format, the chapters include the kind of detailed description and implementation advice that is crucial for getting optimal results in the laboratory. Thorough and intuitive, Transgenic Plants: Methods and Protocols, Second Edition aids scientists in the continuous improvements being made for the production and analysis of transgenic plants.
Book Synopsis Seed Endophytes by : Satish Kumar Verma
Download or read book Seed Endophytes written by Satish Kumar Verma and published by Springer. This book was released on 2019-04-05 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the importance and roles of seed microbiomes in sustainable agriculture by exploring the diversity of microbes vectored on and within seeds of both cultivated and non-cultivated plants. It provides essential insights into how seeds can be adapted to enhance microbiome vectoring, how damaged seed microbiomes can be assembled again and how seed microbiomes can be conserved. Plant seeds carry not only embryos and nutrients to fuel early seedling growth, but also microbes that modulate development, soil nutrient acquisition, and defense against pathogens and other stressors. Many of these microbes (bacteria and fungi) become endophytic, entering into the tissues of plants, and typically exist within plants without inducing negative effects. Although they have been reported in all plants examined to date, the extent to which plants rely on seed vectored microbiomes to enhance seedling competitiveness and survival is largely unappreciated. How microbes function to increase the fitness of seedlings is also little understood. The book is a unique and important resource for researchers and students in microbial ecology and biotechnology. Further, it appeals to applied academic and industrial agriculturists interested in increasing crop health and yield.

Download or read book Dinosaur Tracks written by T. Thulborn and published by Springer. This book was released on 2011-10-05 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ten years ago a book about dinosaur tracks would have appealed to a handful of specialists. Today, it is likely to attract wider interest, in the wake of some major controversies about the natural history of dinosaurs. Few readers will be completely unaware of those spirited debates about 'cold~blooded' versus 'warm~blooded' dinosaurs, and eyebrows are no longer raised at the suggestion that dinosaurs may still be alive and kicking - in the guise of birds. Issues such as these have prompted many biologists and palaeontologists to take a serious second look at the everyday lives and habits of dinosaurs, and in doing so they have begun to turn their attention to the long~neglected study of fossil tracks - the direct testimony of dinosaur behaviour. This resurgence of interest in dinosaur tracks might legitimately be described as a renaissance, and its extent may be gauged from the success of the First International Symposium on Dinosaur Tracks and Traces, held in May 1986 at the New Mexico Museum of Natural History, Albuquerque. The proceedings of that symposium, which attracted no fewer than 60 contributions from researchers in 14 coun~ tries, were published recently by Cambridge University Press under the title Dinosaur Tracks and Traces, edited by D.D. Gillette and M.G.
