Download or read book Drosophila Inversion Polymorphism written by Costas B. Krimbas and published by CRC Press. This book was released on 1992-08-21 with total page 680 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inversion polymorphism in Drosophila has long served as a research subject for a variety of evolutionary studies and continues to be extremely important in understanding evolutionary principles today. Until now, no single volume has ever been assembled as a summary of this work. Drosophila Inversion Polymorphism provides background information, explores new and rigorous approaches to reconstructing phylogenetic relationships from inversion variation, and discusses inversion polymorphism in the six most studied species groups. Some chapters examine general principles and conclusions, some present detailed data sets (many of which have never before been published), and others offer detailed chromosome maps for identification. The book is a one-of-a-kind source of summary discussions and data ripe for analysis. Geneticists, evolutionary biologists, biologists, and all investigators researching inversion polymorphisms should consider Drosophila Inversion Polymorphism a "must-have" volume.

This book was released on 2012-12-06 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: An overview of speciation theory reveals an increasingly held view that many events leading to the origin of new species occur in transient, unstable populations. A transient, unstable population should be under stood as a fast episodic phase in a population subjected to genetic and environmental factors that tend to disrupt its cohesive, balanced genome architecure, thus enhancing its probability to produce a new species. Striking the core of Darwinian thought, some authors claim that these· processes may be non-adaptive. Among the environmental factors one may cite biotic (e.g. resource availability) and abiotic (e.g. temperature) stress conditions that break up the population stability producing random, unpredictable changes in population size, population trait distribution, breeding structure, inter- and/or intrapopulational hybridization, etc. Genetic factors consist of those events that induce rapid changes in genetic expression and/or that determine reproductive isolation, such as substitutions, insertions, deletions, duplications, transpositions, gross chromosomal rearrangements, recombination and, in general, any mechanism that changes the regulatory pattern of the organism or the balance of its meiotic system. Both kinds of factors are often intertwined in a complex net and may influence each other.

Book excerpt: An accessible software package which allows individuals to develop models on the impact of climate in both plants and animals. CLIMEX is used in over 20 countries to examine the distribution of insects, plants, pathogens and vertebrates for a variety of purposes, including biogeography in quarantine, biological control strategies and impacts of changes in climate and climate variability. It can be used to compare climate at different locations, compare climate across a number of years and to match climates against pre-set criteria.

Download or read book Drosophila written by Therese A. Markow and published by Elsevier. This book was released on 2005-11-01 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anyone wishing to tap the research potential of the hundreds of Drosophila species in addition to D.melanogaster will finally have a single comprehensive resource for identifying, rearing and using this diverse group of insects. This is the only group of higher eukaryotes for which the genomes of 12 species have been sequenced.The fruitfly Drosophila melanogaster continues to be one of the greatest sources of information regarding the principles of heredity that apply to all animals, including humans. In reality, however, over a thousand different species of Drosophila exist, each with the potential to make their own unique contributions to the rapidly changing fields of genetics and evolution. This book, by providing basic information on how to identify and breed these other fruitflies, will allow investigators to take advantage, on a large scale, of the valuable qualities of these other Drosophila species and their newly developed genomic resources to address critical scientific questions.* Provides easy to use keys and illustrations to identify different Drosophila species* A guide to the life history differences of hundreds of species* Worldwide distribution maps of hundreds of species* Complete recipes for different Drosophila diets* Offers an analysis on how to account for species differences in designing and conducting experiments* Presents useful ideas of how to collect the many different Drosophila species in the wild

Download or read book Progress and Prospects in Evolutionary Biology written by Jeffrey R. Powell and published by Oxford University Press, USA. This book was released on 1997 with total page 577 pages. Available in PDF, EPUB and Kindle. Book excerpt: The common fruitfly, Drosophila, is the most extensively studied of all organisms in genetical research. Thus, it would appear to be the best model for achieving new insights. Its use in evolutionary studies has resulted in an explosion of knowledge which has never before been gathered into a single volume. This book spans the full range of evolutionary studies - population genetics, ecology, ecological genetics, speciation, phylogenetics, genome evolution, molecular; evolution, and development. In covering these topics, highlights of empirical research are emphasized and are put into the context of major issues in evolution.

Download or read book Mechanisms of Life History Evolution written by Thomas Flatt and published by OUP Oxford. This book was released on 2011-05-12 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: Life history theory seeks to explain the evolution of the major features of life cycles by analyzing the ecological factors that shape age-specific schedules of growth, reproduction, and survival and by investigating the trade-offs that constrain the evolution of these traits. Although life history theory has made enormous progress in explaining the diversity of life history strategies among species, it traditionally ignores the underlying proximate mechanisms. This novel book argues that many fundamental problems in life history evolution, including the nature of trade-offs, can only be fully resolved if we begin to integrate information on developmental, physiological, and genetic mechanisms into the classical life history framework. Each chapter is written by an established or up-and-coming leader in their respective field; they not only represent the state of the art but also offer fresh perspectives for future research. The text is divided into 7 sections that cover basic concepts (Part 1), the mechanisms that affect different parts of the life cycle (growth, development, and maturation; reproduction; and aging and somatic maintenance) (Parts 2-4), life history plasticity (Part 5), life history integration and trade-offs (Part 6), and concludes with a synthesis chapter written by a prominent leader in the field and an editorial postscript (Part 7).
