Download or read book Variation written by Benedikt Hallgrímsson and published by Elsevier. This book was released on 2011-05-04 with total page 594 pages. Available in PDF, EPUB and Kindle. Book excerpt: Darwin's theory of evolution by natural selection was based on the observation that there is variation between individuals within the same species. This fundamental observation is a central concept in evolutionary biology. However, variation is only rarely treated directly. It has remained peripheral to the study of mechanisms of evolutionary change. The explosion of knowledge in genetics, developmental biology, and the ongoing synthesis of evolutionary and developmental biology has made it possible for us to study the factors that limit, enhance, or structure variation at the level of an animals' physical appearance and behavior. Knowledge of the significance of variability is crucial to this emerging synthesis. Variation situates the role of variability within this broad framework, bringing variation back to the center of the evolutionary stage. Provides an overview of current thinking on variation in evolutionary biology, functional morphology, and evolutionary developmental biology Written by a team of leading scholars specializing on the study of variation Reviews of statistical analysis of variation by leading authorities Key chapters focus on the role of the study of phenotypic variation for evolutionary, developmental, and post-genomic biology
Download or read book Types of Variation written by Terttu Nevalainen and published by John Benjamins Publishing. This book was released on 2006-01-01 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume interfaces three fields of linguistics rarely discussed in the same context. Its underlying theme is linguistic variation, and the ways in which historical linguists and dialectologists may learn from insights offered by typology, and vice versa. The aim of the contributions is to raise the awareness of these linguistic subdisciplines of each other and to encourage their cross-fertilization to their mutual benefit. If linguistic typology is to unify the study of all types of linguistic variation, this variation, both diatopic and diachronic, will enrich typological research itself. With the aim of capturing the relevant dimensions of variation, the studies in this volume make use of new methodologies, including electronic corpora and databases, which enable cross- and intralinguistic comparisons dialectally and across time. Based on original research and unified by an innovative theme, the volume will be of interest to both students and teachers of linguistics and Germanic languages.

Download or read book Applications of Toxicogenomic Technologies to Predictive Toxicology and Risk Assessment written by National Research Council and published by National Academies Press. This book was released on 2007-12-19 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: The new field of toxicogenomics presents a potentially powerful set of tools to better understand the health effects of exposures to toxicants in the environment. At the request of the National Institute of Environmental Health Sciences, the National Research Council assembled a committee to identify the benefits of toxicogenomics, the challenges to achieving them, and potential approaches to overcoming such challenges. The report concludes that realizing the potential of toxicogenomics to improve public health decisions will require a concerted effort to generate data, make use of existing data, and study data in new waysâ€"an effort requiring funding, interagency coordination, and data management strategies.

Available in PDF, EPUB and Kindle. Book excerpt: Genetic diversity is one of the measures of biodiversity and has consequences in biological variation. It is crucial to understand the evolutionary and adaptative processes in all living species. This book is an interdisciplinary and integrated work that will contribute to the knowledge of academics from different areas of biological sciences. This collection of scientific papers was chosen and analyzed to offer readers a broad and integrated view of the importance of genetic diversity in the evolution and adaptation of living beings, as well as practical applications of the information needed to analyze this diversity in different organisms. This book was edited by geneticist researchers and provides academics with up-to-date and quality information on the subject.

Download or read book Virus as Populations written by Esteban Domingo and published by Academic Press. This book was released on 2019-11-06 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: Virus as Composition, Complexity, Quasispecies, Dynamics, and Biological Implications, Second Edition, explains the fundamental concepts surrounding viruses as complex populations during replication in infected hosts. Fundamental phenomena in virus behavior, such as adaptation to changing environments, capacity to produce disease, and the probability to be transmitted or respond to treatment all depend on virus population numbers. Concepts such as quasispecies dynamics, mutations rates, viral fitness, the effect of bottleneck events, population numbers in virus transmission and disease emergence, and new antiviral strategies are included. The book's main concepts are framed by recent observations on general virus diversity derived from metagenomic studies and current views on the origin and role of viruses in the evolution of the biosphere. Features current views on key steps in the origin of life and origins of viruses Includes examples relating ancestral features of viruses with their current adaptive capacity Explains complex phenomena in an organized and coherent fashion that is easy to comprehend and enjoyable to read Considers quasispecies as a framework to understand virus adaptability and disease processes
Download or read book Variation in Linguistic Systems written by James A. Walker and published by Routledge. This book was released on 2012-07-26 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tying together work on a number of languages and linguistic varieties in different locales, this book provides students and researchers with a convenient, unified overview of variationist analysis in linguistics. Variation in Linguistic Systems takes a theoretical and quantitative approach to the study of variation in language, focusing on the role of language-internal constraints on variation and the relation of linguistic variation to linguistic theory. It introduces the basic concepts of variationist linguistics and includes key discussions on language change, language contact, the different types of variation, multivariate analysis with GoldVarb, and variation in sound and grammatical systems. Here is an ideal textbook for an introductory course on variation, as well as a useful resource for scholars with some background in linguistics who are interested in the study of language variation and its relation to the wider field of linguistics.

Download or read book Human Variation written by Stephen Molnar and published by Prentice Hall. This book was released on 1983 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Discarding race as misleading, Human Variation: Races, Types, and Ethnic Groups examines the biology of human variation at the population level. It argues that diversity is a reflection of humans' ability to adapt to environments, organize activities, and regulate breeding behavior. This book reviews the history, behavior, and demography of contemporary populations and the distribution of major distinctions of body form, size, and skin color. The book traces the concept of race and analyzes faulty perceptions of human differences and issues of racism on assumed inherited inequality. It incorporates the latest DNA technology into a discussion of genetic markers including their adaptive significance. It also reviews ongoing evolution. The fourth edition of Human Variation: Races, Types, and Ethnic Groups has been revised to include a reorganization of chapters to unite discussions of inherited traits with explanations of their adaptive significance. The book also includes the latest data and a glossary of the latest terminology. A valuable reference book for any reader interested in the biological diversity of the human species.
