Evolutionary Biology of Transient Unstable Populations by Antonio Fontdevila Pdf

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.

Evolutionary Biology of Transient Unstable Populations by Antonio Fontdevila Pdf

The biology of transient, unstable populations form the evolutionary stage used to describe events leading to the origin of new species, which is the theme of the present analysis. This problem is approached from different perspectives, ranging from population genetics, population ecology and developmental biology to the molecular level of evolution. Covering these main disciplines involved in the elucidation of evolutionary mechanisms, the present volume bridges the gap between molecularly orientated evolutionists and population biologists. Readers will find a high quality, well balanced set of theoretical and experimental articles authored by leading researchers in the field of evolutionary biology.

Transposable Elements and Evolution by J. F. McDonald Pdf

In the summer of 1992 a distinguished group of molecular, population and evolutionary geneticists assembled on the campus of the University of Georgia in Athens, USA to discuss the relevance of their research to the role played by transposable elements (TEs) in evolution. The meeting consisted of a series of informal discussions of issues brought up in papers written by the participants and distributed among them prior to the meeting. These papers and the transcripts of the ensuing discussions are presented in this volume.

Population Viability in Plants by Christy A. Brigham,Mark W. Schwartz Pdf

Providing a quantitative assessment of threatened plant populations, that holds for varying management scenarios, has become an essential part of conservation planning. Here, renowned plant ecologists provide information on: major threats to plants, when and where to conduct a plant viability assessment (PVA), what type of PVA to conduct, what alternative options to PVA are available, what information is required for which kind of viability assessment, what attributes of the population in question should be considered, and what the limits of the PVA would be. As such, this volume can be used as a training tool for the environmental manager or a teaching aid for reviewing the current state of knowledge on plant population viability.

Molecular Markers, Natural History and Evolution by J. C. Avise Pdf

Molecular approaches have opened new windows on a host of ecological and evolutionary disciplines, ranging from population genetics and behavioral ecology to conservation biology and systematics. Molecular Markers, Natural History and Evolution summarizes the multi-faceted discoveries about organisms in nature that have stemmed from analyses of genetic markers provided by polymorphic proteins and DNAs. The first part of the book introduces rationales for the use of molecular markers, provides a history of molecular phylogenetics, and describes a wide variety of laboratory methods and interpretative tools in the field. The second and major portion of the book provides a cornucopia of biological applications for molecular markers, organized along a scale from micro-evolutionary topics (such as forensics, parentage, kinship, population structure, and intra-specific phylogeny) to macro-evolutionary themes (including species relationships and the deeper phylogenetic structure in the tree of life). Unlike most prior books in molecular evolution, the focus is on organismal natural history and evolution, with the macromolecules being the means rather than the ends of scientific inquiry. Written as an intellectual stimulus for the advanced undergraduate, graduate student, or the practicing biologist desiring a wellspring of research ideas at the interface of molecular and organismal biology, this book presents material in a manner that is both technically straightforward, yet rich with concepts and with empirical examples from the world of nature.

The Biodemography of Human Reproduction and Fertility by Joseph Lee Rodgers,Hans-Peter Kohler Pdf

The book that you hold in your hands is the second in a series. The two titles in the series are the following: Genetic Influences on Human Fertility and Sexuality: Theoretical and Empirical Contributions from the Biological and Behavior Sciences Edited by Joseph Lee Rodgers, David C. Rowe, & Warren B. Miller Published by Kluwer Academic Press, 2000 The Biodemography of Human Reproduction and Fertility Edited by Joseph Lee Rodgers & Hans-Peter Kohler Published by Kluwer Academic Press, 2002 The series has published chapters by researchers who study human fertility, from a particular perspective: Biodemography. We welcome your interest and participation in this developing subfield. Or, perhaps, biodemography may be better referred to as a "superfield. " Because biodemography so naturally crosses interdisciplinary boundaries, and because its application draws together researchers from disparate disciplines, it may well be more appropriate to consider that biodemography subsumes a number of other disciplines, rather than the other way around. In this preface, we will describe our own efforts and those of many others to promote and develop the study of human fertility, using methods, models, and theories from both biological and demographic domains. In December, 1997, 25 participants from three different countries gathered in Tucson, Arizona for a small conference with the title "Genetic Influences on Fertility-Related Processes. " That conference represented a fascinating blending of research from two apparently separate domains.

Life Underground by Eileen A. Lacey Pdf

Many mammals like to dig in the dirt, but few call it home. Those that do, such as mole-rats, zokors, and tuco-tucos, have developed novel adaptations to their subterranean life, including bones and muscles modified for efficient digging and ways to "see" underground without using their eyes. These unusual traits, adopted independently by unrelated groups around the world, also make subterranean rodents fascinating subjects for biologists. Life Underground provides the first comprehensive review of the biology of subterranean rodents. Arranged by topic rather than by taxon to facilitate cross-species comparisons, chapters cover such subjects as morphology, physiology, social behavior, genetic variation, and evolutionary diversification. Two main questions run throughout the book. First, to what extent has subterranean life shaped the biology of these animals, leading to similar adaptations among otherwise dissimilar species? Second, how have the distinct evolutionary histories of these groups led to different solutions to the challenges posed by life underground?

Experimental Evolution by Theodore Garland,Michael R. Rose Pdf

Experimental approaches to evolution provide indisputable evidence of evolution by directly observing the process at work. Experimental evolution deliberately duplicates evolutionary processes—forcing life histories to evolve, producing adaptations to stressful environmental conditions, and generating lineage splitting to create incipient species. This unique volume summarizes studies in experimental evolution, outlining current techniques and applications, and presenting the field’s full range of research—from selection in the laboratory to the manipulation of populations in the wild. It provides work on such key biological problems as the evolution of Darwinian fitness, sexual reproduction, life history, athletic performance, and learning.

Macroecology by James H. Brown Pdf

In Macroecology, James H. Brown proposes a radical new research agenda designed to broaden the scope of ecology to encompass vast geographical areas and very long time spans. While much ecological research is narrowly focused and experimental, providing detailed information that cannot be used to generalize from one ecological community or time period to another, macroecology draws on data from many disciplines to create a less detailed but much broader picture with greater potential for generalization. Integrating data from ecology, systematics, evolutionary biology, paleobiology, and biogeography to investigate problems that could only be addressed on a much smaller scale by traditional approaches, macroecology provides a richer, more complete understanding of how patterns of life have moved across the earth over time. Brown also demonstrates the advantages of macroecology for conservation, showing how it allows scientists to look beyond endangered species and ecological communities to consider the long history and large geographic scale of human impacts. An important reassessment of the direction of ecology by one of the most influential thinkers in the field, this work will shape future research in ecology and other disciplines. "This approach may well mark a major new turn in the road in the history of ecology, and I find it extremely exciting. The scope of Macroecology is tremendous and the book makes use of its author's exceptionally broad experience and knowledge. An excellent and important book."—Lawrence R. Heaney, Center for Environmental and Evolutionary Biology, the Field Museum
