Available in PDF, EPUB and Kindle. Book excerpt: Traditionally, studies in ecological genetics have involved both field observations and laboratory genetic analyses. Comparisons and cor relations between these two kinds of data have provided valuable in formation on the genetic strategies behind the evolutionary adapta tions of species and their component local populations. Indeed, much of our current understanding of the dynamics of evolutionary pro cesses has come fro~ syntheses of ecological and genetic information. Since the recent discovery of abundant markers in the form of protein polymorphisms, scientific interest in the connections between genetics and ecology has quickened considerably. This volume contains the proceedings of the Society for the Study of Evolution's symposium, Genetics and Ecology: The Interface, held at Ithaca College, Ithaca, New York, June 12-15, 1977. This particular topic was selected because of a general feeling that a significant integration of genetics and ecology has developed in the last decade or so. Host ecologists no longer believe that each species has a characteristic and constant birth, death, and develonment rate, habitat preference, and so on, but that these para~eters vary a~ong populations and are at least partially under genetic control and sub ject to natural selection. Similarly, few population geneticists still view any species as infinitely large, panmictic, constant in numbers, and distributed evenly throughout its range.

Download or read book Drosophila melanogaster Drosophila simulans So Similar So Different written by Pierre Capy and published by Springer Science & Business Media. This book was released on 2004-03-31 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together most of the information available concerning two species that diverged 2-3 million years ago. The objective was to try to understand why two sibling species so similar in several characteristics can be so different in others. To this end, it was crucial to confront all data from their ecology and biogeography with their behavior and DNA polymorphism. Drosophila melanogaster and Drosophila simulans are among the two sibling species for which a large set of data is available. In this book, ecologists, physiologists, geneticists, behaviorists share their data on the two sibling species, and several scenarios of evolution are put forward to explain their similarities and divergences. This is the first collection of essays of its kind. It is not the final point of the analyses of these two species since several areas remain obscure. However, the recent publication of the complete genome of D. melanogaster opens new fields for research. This will probably help us explain why D. melanogaster and D. simulans are sibling species but false friends.

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 Drosophilidae Diptera written by Irina Brake and published by BRILL. This book was released on 2013-01-21 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concerns about global biodiversity are rising dramatically, yet we are lagging behind in the most basic prerequisite for its understanding and conservation: the inventory. Insect species may make up five or ten times the number of all other plant and animal species combined, and as such they represent one of the major challenges in biosystematic science. World Catalogue of Insects is an initiative aiming at compiling worldscale, authoritative catalogues of monophyletic insect taxa. Volumes in this series contain standard nomenclatoral information on all names pertaining to the taxon treated, including type locality and distribution to the extent this is relevant. Additional information is optional, e.g., location, status and condition of types; biology; bibliographical information; pest status; vector status; etc. This volume nine focuses on Drosophilidae (Diptera).

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.

Download or read book Epigenetic Principles of Evolution written by Nelson R Cabej and published by Elsevier. This book was released on 2011-11-22 with total page 847 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first and only book, so far, to deal with the causal basis of evolution from an epigenetic view. By revealing the epigenetic "user" of the "genetic toolkit", this book demonstrates the primacy of epigenetic mechanisms and epigenetic information in generating evolutionary novelties. The author convincingly supports his theory with a host of examples from the most varied fields of biology, by emphasizing changes in developmental pathways as the basic source of evolutionary change in metazoans. - Original and thought provoking--a radically new theory that overcomes the present difficulties of the theory of evolution - Is the first and only theory that uses epigenetic mechanisms and principles for explaining evolution of metazoans - Takes an integrative approach and shows a wide range of learning

Download or read book Ecological Speciation written by Patrik Nosil and published by OUP Oxford. This book was released on 2012-03-15 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: The origin of biological diversity, via the formation of new species, can be inextricably linked to adaptation to the ecological environment. Specifically, ecological processes are central to the formation of new species when barriers to gene flow (reproductive isolation) evolve between populations as a result of ecologically-based divergent natural selection. This process of 'ecological speciation' has seen a large body of particularly focused research in the last 10-15 years, and a review and synthesis of the theoretical and empirical literature is now timely. The book begins by clarifying what ecological speciation is, its alternatives, and the predictions that can be used to test for it. It then reviews the three components of ecological speciation and discusses the geography and genomic basis of the process. A final chapter highlights future research directions, describing the approaches and experiments which might be used to conduct that future work. The ecological and genetic literature is integrated throughout the text with the goal of shedding new insight into the speciation process, particularly when the empirical data is then further integrated with theory.

Download or read book Evolutionary Quantitative Genetics written by Derek A. Roff and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: The impetus for this book arose out of my previous book, The Evolution of Life Histories (Roff, 1992). In that book I presented a single chapter on quanti tative genetic theory. However, as the book was concerned with the evolution of life histories and traits connected to this, the presence of quantitative genetic variation was an underlying theme throughout. Much of the focus was placed on optimality theory, for it is this approach that has proven to be extremely successful in the analysis of life history variation. But quantitative genetics cannot be ig nored, because there are some questions for which optimality approaches are inappropriate; for example, although optimality modeling can address the ques tion of the maintenance of phenotypic variation, it cannot say anything about genetic variation, on which further evolution clearly depends. The present book is, thus, a natural extension of the first. I have approached the problem not from the point of view of an animal or plant breeder but from that of one interested in understanding the evolution of quantitative traits in wild populations. The subject is large with a considerable body of theory: I generally present the assumptions underlying the analysis and the results, giving the relevant references for those interested in the intervening mathematics. My interest is in what quantitative genetics tells me about evolutionary processes; therefore, I have concentrated on areas of research most relevant to field studies.

The combination of evolution and sperm is a potent mix, and this is the definitive account. - The first review survey of this emerging field - Written by experts from a broad array of disciplines from the physiological and biomedical to the ecological and evolutionary - Sheds light on the intricacies of reproduction and the coevolution of sperm, egg and reproductive behavior

Download or read book Speciation written by Pawel Michalak and published by Nova Science Publishers. This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The origin of species, or speciation, the "mystery of mysteries", as Charles Darwin called it, is an issue at the very heart of evolutionary biology, critical to understanding the mechanisms behind the great diversity of life around us. This book is centred around three major research areas: (1) biodiversity patterns in relation to speciation scenarios; (2) mechanisms that produce pre- and postzygotic reproductive isolation and adaptive divergence; as well as (3) genetics, epigenetics, and genomics of speciation. Being a mishmash of new ideas, reviews, conventional and nonconventional case studies, this collection demonstrates more than anything how research can benefit from integration of traditionally divergent disciplines, such as biogeography, paleontology, taxonomy, molecular genetics, proteomics, and genomics.
