This book was released on 2012-12-06 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two Symposia on speciation in insects held at the Fourteenth International Congress of Entomology (Canberra, Australia, August 22-30, 1972) are included in this volume. The first, on the more general topic of Genetic Analysis of Speciation Mechanisms, includes four papers on speciation in various groups of Diptera and Orthopteroid insects. The second symposium was devoted to the topic of Evolution in the Hawaiian Drosophilidae; it deals with the explosive speciation of a group of flies with specialized ecological requirements in the complex ecolOgical habitats provided by a recent tropical volcanic archipelago. The Hawaiian Symposium, organized by Professor D. Elmo Hardy, is the latest outcome of a major collaborative research project involving over 20 scientists and about 125 technical assistants over a period of ten years. Some recent books on evolution have taken the standpoint that the funda mental genetic mechanism of speciation is relatively uniform and stereotyped and, in particular, that the 'allopatric' model of its geographic component is universally valid. Certainly, this has been a rather generally accepted viewpoint on the part of students of vertebrate speciation. Workers on speciation in insects have tended, in general, to be less dogmatic and more willing to consider a variety of alternative models of speciation. Thus, in the present volume, several contributions adopt viewpoints which are unorthodox or novel. Only time will tell whether their conclusions will turn out to have been soundly based.

Download or read book Genetic Structure and Local Adaptation in Natural Insect Populations written by Susan Mopper and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: Providing an essential foundation for evolutionary theory, this comprehensive volume examines patterns of genetic variation within natural insect populations, and explores the underlying mechanisms that lead to the genetic divergence of coexisting organisms. In particular, the text investigates current research on finescale genetic structure in natural insect populations. Internationally renowned scientists offer a wealth of current information not previously published. Part I present case studies of adaptive genetic structure in natural insect populations, including a critical discussion of the strenghts and weaknesses of the experimental methods employed. Part II addresses the ecological mechanisms that produce adaptive genetic structure in natural insect populations. Part III describes how behavioral and life-history patterns influence genetic structure. Finally, Part IV combines theoretical and empirical approaches linking genetic structure at the population level with larger-scale patterns of variation, such as host race formation and speciation. This broad-ranging, interdisciplinary source of information supplies a thorough examination of the mechanisms that promote and impede genetic structure in natural insect populations. It is a book that will be of interest to undergraduate and graduate students, and to researchers in the fields of ecology, evolution, insect and plant systems, entomology, and population genetics.

Book excerpt: The Arthur M. Sackler Colloquia of the National Academy of Sciences address scientific topics of broad and current interest, cutting across the boundaries of traditional disciplines. Each year, four or five such colloquia are scheduled, typically two days in length and international in scope. Colloquia are organized by a member of the Academy, often with the assistance of an organizing committee, and feature presentations by leading scientists in the field and discussions with a hundred or more researchers with an interest in the topic. Colloquia presentations are recorded and posted on the National Academy of Sciences Sackler colloquia website and published on CD-ROM. These Colloquia are made possible by a generous gift from Mrs. Jill Sackler, in memory of her husband, Arthur M. Sackler.

Available in PDF, EPUB and Kindle. Book excerpt: Speciation is one of the great themes of evolutionary biology. It is the process through which new species are born and diversity generated. Yet for many years our understanding of the process consisted of little more than a perception that if populations are isolated geographically, they will diverge genetically and may come to form new species. This situation began to change in the 1960s as an increasing number of biologists challenged the exclusivity of allopatric speciation and began to probe more deeply into the actual process by which divergence occurs and reproductive isolation is acquired. This focus on process led to many new insights, but numerous questions remain and speciation is now one of the most dynamic areas of research in modern evolutionary biology. This volume presents the newest research findings on speciation bringing readers up to day on species concepts, modes of speciation, and the nature of reproductive barriers. It also discusses the forces that drive divergence of populations, the genetic control of reproductive isolation, and the role played by hybrid zones and hybridization in speciation.

Available in PDF, EPUB and Kindle. Book excerpt: "This volume captures the state-of-the-art in the study of insect-plant interactions, and marks the transformation of the field into evolutionary biology. The contributors present integrative reviews of uniformly high quality that will inform and inspire generations of academic and applied biologists. Their presentation together provides an invaluable synthesis of perspectives that is rare in any discipline."--Brian D. Farrell, Professor of Organismic and Evolutionary Biology, Harvard University "Tilmon has assembled a truly wonderful and rich volume, with contributions from the lion's share of fine minds in evolution and ecology of herbivorous insects. The topics comprise a fascinating and deep coverage of what has been discovered in the prolific recent decades of research with insects on plants. Fascinating chapters provide deep analyses of some of the most interesting research on these interactions. From insect plant chemistry, behavior, and host shifting to phylogenetics, co-evolution, life-history evolution, and invasive plant-insect interaction, one is hard pressed to name a substantial topic not included. This volume will launch a hundred graduate seminars and find itself on the shelf of everyone who is anyone working in this rich landscape of disciplines."--Donald R. Strong, Professor of Evolution and Ecology, University of California, Davis "Seldom have so many excellent authors been brought together to write so many good chapters on so many important topics in organismic evolutionary biology. Tom Wood, always unassuming and inspired by living nature, would have been amazed and pleased by this tribute."--Mary Jane West-Eberhard, Smithsonian Tropical Research Institute

Download or read book Genetics Speciation and the Founder Principle written by Luther Val Giddings and published by . This book was released on 1989 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the genetic mechanisms that govern the development and evolution of animals and plants. In particular, the book focuses on animal and plant species evolving in isolated habitats and species colonizing new territories. This approach--studying "founder" populations--enables geneticists to more readily identify some of the evolutionary pressures affecting the speciation process. The Founder Principle in population genetics was elucidated in large part by Hampton Carson in classic studies of Hawaiian fruit flies (Drosophila). The editors of this volume have commissioned seventeen chapters by an internationally recognized group of geneticists who discuss the principle in relation to plant speciation, chromosomal evolution, molecular evolution and development, sexual selection, and genetic changes in natural populations.
