Book Synopsis Mating Systems and Strategies by : Stephen M. Shuster
Download or read book Mating Systems and Strategies written by Stephen M. Shuster and published by Princeton University Press. This book was released on 2003-05-26 with total page 546 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the first unified conceptual and statistical framework for understanding the evolution of reproductive strategies. Using the concept of the opportunity for sexual selection, the authors illustrate how and why sexual selection, though restricted to one sex and opposed in the other, is one of the strongest and fastest of all evolutionary forces. They offer a statistical framework for studying mating system evolution and apply it to patterns of alternative mating strategies. In doing so, they provide a method for quantifying how the strength of sexual selection is affected by the ecological and life history processes that influence females' spatial and temporal clustering and reproductive schedules. Directly challenging verbal evolutionary models that attempt to explain reproductive behavior without quantitative reference to evolutionary genetics, this book establishes a more solid theoretical foundation for the field. Among the weaknesses the authors find in the existing data is the apparent ubiquity of condition-dependent mating tactics. They identify factors likely to contribute to the evolution of alternative mating strategies--which they argue are more common than generally believed--and illustrate how to measure the strength of selection acting on them. Lastly, they offer predictions on the covariation of mating systems and strategies, consider the underlying developmental biology behind male polyphenism, and propose directions for future research. Informed by genetics, this is a comprehensive and rigorous new approach to explaining mating systems and strategies that will influence a wide swath of evolutionary biology.
Book Synopsis Alternative Reproductive Tactics by : Rui F. Oliveira
Download or read book Alternative Reproductive Tactics written by Rui F. Oliveira and published by Cambridge University Press. This book was released on 2008-03-13 with total page 490 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of alternative reproductive tactics (the behavioural strategies used by individuals to increase their reproductive success) is an evolutionary puzzle, and one of great interest to researchers. For instance, why do some males guard both nest and eggs, while others sneak into nests while pairs are spawning and fertilise those eggs? The field offers a special opportunity to study the evolution and functional causes of phenotypic variation, which is a general problem in the field of evolutionary biology. By integrating both mechanistic (psychological) and evolutionary (behavioural ecology) perspectives and by covering a great diversity of species, Alternative Reproductive Tactics addresses this integrated topic of longstanding interest, bringing together a multitude of otherwise scattered information in an accessible form that is ideal for graduate students and researchers.

Book Synopsis The Evolution of Sex by : John Maynard Smith
Download or read book The Evolution of Sex written by John Maynard Smith and published by Cambridge University Press. This book was released on 1978-08-24 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: The question of why organisms reproduce sexually is still a matter of controversy. In this account, Professor Maynard Smith considers the selective forces responsible for the origin and evolution of sexual reproduction and genetic recombination, using quantitative population genetics arguments to support his ideas. The relative importance of individual and group selection processes are also considered. the aim is to give a clear statement of the theoretical issues, and present enough of the evidence to show what kinds of facts are relevant. It is hoped that where crucial evidence is missing, experimentalists and field workers may be encouraged to collect the relevant data. The author does not claim to solve all the problems he raises, but this clear and well-argued account should provide stimulating reading for advanced undergraduate students and research workers in evolutionary theory.
Book Synopsis Genotype-by-Environment Interactions and Sexual Selection by : John Hunt
Download or read book Genotype-by-Environment Interactions and Sexual Selection written by John Hunt and published by John Wiley & Sons. This book was released on 2014-10-20 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sexual selection is recognized as being responsible for some of the most extravagant morphologies and behaviors in the natural world, as well as a driver of some of the most rapid evolution. While Charles Darwin’s theory is now a fundamental component of modern evolutionary biology, the impact of genotype-by-environment interactions on sexual selection has thus far received little attention. This book represents the first comprehensive analysis of the role genotype-by-environment interactions play in sexual selection and the potential implications that they have for the evolutionary process. The Editors have identified 13 topics that currently define the field and shed light on the impacts of these interactions on sexual selection. This includes key topics, such as resolving the lek paradox and how genotype-by-environmental interactions can compromise the honesty of sexual signals. The volume also outlines key questions that remain unanswered and provides a comprehensive guide to analyzing genotype-by-environment interactions. The mix of theory, empirical studies, and practical instructions from world leading experts make this book a particularly potent and definitive guide on the topic. It will be of interest to evolutionary biologists, spanning from genomicists to behaviorists. “This is a very timely book, covering a topic that should change the way we think about sexual selection. The contributors are all leaders and the topics should provide guidance to many PhD projects in the years to come. GEI is increasingly shown to be important, and it seems likely that it is critical in species where sexual selection is operating. This book is likely to help revitalize the study of sexual selection.” Professor Allen Moore, The University of Georgia “GEIs fascinate evolutionary biologists, but the unique consequences for sexually selected traits have been neglected - until now. This multi-authored book comprehensively explains key theoretical concepts, handles practical ‘how to’ issues and uses classic case studies to illustrate the value of studying GEIs. It is a must read for everyone interested in sexual selection.” Professor Michael Jennions, The Australian National University

Book Synopsis Adaptive Genetic Variation in the Wild by : Timothy A. Mousseau
Download or read book Adaptive Genetic Variation in the Wild written by Timothy A. Mousseau and published by Oxford University Press. This book was released on 2000-01-13 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two of the great mysteries of biology yet to be explored concern the distribution and abundance of genetic variation in natural populations and the genetic architecture of complex traits. These are tied together by their relationship to natural selection and evolutionary history, and some of the keys to disclosing these secrets lie in the study of wild organisms in their natural environments. This book, featuring a superb selection of papers from leading authors, summarizes the state of current understanding about the extent of genetic variation within wild populations and the ways to monitor such variation. It proposes the idea that a fundamental objective of evolutionary ecology is necessary to predict organism, population, community, and ecosystem response to environmental change. In fact, the overall theme of the papers centers around the expression of genetic variation and how it is shaped by the action of natural selection in the natural environment. Patterns of adaptation in the past and the genetic basis of traits likely to be under selection in a dynamically changing environment is discussed along with a wide variety of techniques to test for genetic variation and its consequences, ranging from classical demography to the use of molecular markers. This book is perfect for professionals and graduate students in genetics, biology, ecology, conservation biology, and evolution.

Book Synopsis Sexual Selection by : Regina H. Macedo
Download or read book Sexual Selection written by Regina H. Macedo and published by Academic Press. This book was released on 2013-09-25 with total page 479 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sexual Selection: Perspectives and Models from the Neotropics presents new sexual selection research based upon neotropical species. As neotropical regions are destroyed at an alarming rate, with an estimated 140 species of rainforest plants and animals going extinct every day, it is important to bring neotropical research to the fore now. Sexual selection occurs when the male or female of a species is attracted by certain characteristics such as form, color or behavior. When those features lead to a greater probability of successful mating, they become more prominent in the species. Although most theoretical concepts concerning sexual selection and reproductive strategies are based upon North American and European fauna, the Neotropical region encompasses much more biodiversity, with as many as 15,000 plant and animal species in a single acre of rain forest. This book illustrates concepts in sexual selection through themes ranging from female cryptic choice in insects, sexual conflict in fish, interaction between sexual selection and the immune system, nuptial gifts, visual and acoustic sexual signaling, parental investment, to alternative mating strategies, among others. These approaches distinguish Sexual Selection from current publications in sexual selection, mainly because of the latitudinal and taxonomic focus, so that readers will be introduced to systems mostly unknown outside the tropics, several of which bring into question some well-established patterns for temperate regions. Synthesizes sexual selection research on species from the Neotropics Combines different perspectives and levels of analysis using a broad taxonomic basis, introducing readers to systems mostly unknown outside the tropics and bringing into question well-established patterns for temperate regions Includes contributions exploring concepts and theory as well as discussions on a variety of Neotropical vertebrates and invertebrates, such as insects, fish, arthropods and birds
Book Synopsis Sociobiology: Beyond Nature/nurture? by : George W Barlow
Download or read book Sociobiology: Beyond Nature/nurture? written by George W Barlow and published by Routledge. This book was released on 2019-06-26 with total page 513 pages. Available in PDF, EPUB and Kindle. Book excerpt: To most biologists, sociobiology represents the concept of strict Darwinian individual selection married to an analytical application of ecological principles and brought to bear on social behavior in an unusually exciting and productive way. Joining the biologists are a small number of social scientists. But there are radically divergent views as to how the field should be delimited, and sociobiology is one of the most widely discussed fields in biology and anthropology today. The symposium on which this book is based was arranged by a biologist and an anthropologist. The participants, leaders in their fields, ably present contrasting and responsible views on current issues. This is the first collection of essays on sociobiology in which opposing views are aired. It is an exciting, timely book and an important historical document.
Book Synopsis Offspring by : National Research Council
Download or read book Offspring written by National Research Council and published by National Academies Press. This book was released on 2003-05-04 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite recent advances in our understanding of the genetic basis of human behavior, little of this work has penetrated into formal demography. Very few demographers worry about how biological processes might affect voluntary behavior choices that have demographic consequences even though behavioral geneticists have documented genetics effects on variables such as parenting and divorce. Offspring: Human Fertility Behavior in Demographic Perspective brings together leading researchers from a wide variety of disciplines to review the state of research in this emerging field and to identify promising research directions for the future.
Book Synopsis The Evolution of Anisogamy by : Tatsuya Togashi
Download or read book The Evolution of Anisogamy written by Tatsuya Togashi and published by Cambridge University Press. This book was released on 2011-04-14 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: Darwin identified the existence of separate male and female gametes as one of the central mysteries of evolutionary biology. 150 years later, the question of why male gametes exist remains an intriguing puzzle. In this, the first book solely devoted to the evolution of anisogamy, top theorists in the field explore why gamete dimorphism characterizes nearly all plants and animals. Did separate male and female gametes evolve as a result of competition, or does anisogamy instead represent selection for cooperation? If disruptive selection drove the evolution of anisogamy, with male gametes focused on search and fusion, and female gametes provisioning the new zygote, why do some algal species continue to produce gametes of a single size? Does sperm limitation, or escape from infection, better explain the need for extremely small, highly mobile sperm? Written by leaders in the field, this volume offers an authoritative and cutting-edge overview of evolutionary theory.
Download or read book Lost Sex written by Isa Schön and published by Springer Science & Business Media. This book was released on 2009-09-22 with total page 617 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sex is the queen of problems in evolutionary biology. Generations of researchers have investigated one of the last remaining evolutionary paradoxes: why sex exists at all. Given that sexual reproduction is costly from an evolutionary point of view, one could wonder why not all animals and plants reproduce asexually. Dozens of contemporary hypotheses attempt to explain the prevalence of sex and its advantages and predict the early extinction of fully asexual lineages. The major theme of this book is: what is the fate of animal and plant groups in which sex is lost? Initial chapters discuss theory behind asexual life: what major disadvantages do asexual groups have to face, what are the genetic and ecological consequences and what does this theory predict for more applied aspects of asexual life, for example in agricultural pests, diseases as well as in cultural crops such as grapes. Cases studies in many animals (focusing on both invertebrates and vertebrates) and plants reveal parallel, but also singularly novel adaptations to the absence of meiosis and syngamy. And last but not least, are asexuals really doomed to early extinction or do genuine ancient asexuals exist? This book assembles contributions from the most important research groups dealing with asexual evolution in eukaryotes. It is a milestone in research on parthenogenesis and will be useful to undergraduate as well as graduate students and to senior researchers in all fields of evolutionary biology, as the paradox of sex remains its queen of problems.
Book Synopsis Life History Evolution by : Derek A. Roff
Download or read book Life History Evolution written by Derek A. Roff and published by Sinauer Associates Incorporated. This book was released on 2002 with total page 527 pages. Available in PDF, EPUB and Kindle. Book excerpt: Life History Evolution represents a synthetic approach to the understanding of the evolution of life history variation using the three types of environment (constant, stochastic, predictable) as the focus under which the theory is developed and tested. First, the author outlines a general framework for the study and analysis of life history variation, bringing together the approaches of quantitative genetic modeling and optimality analysis. Using this framework, he then discusses how life histories evolve in the three different types of environments, each of which presents unique characteristics. The theme of the book is that an understanding of evolutionary change requires analysis at both the genetic and phenotypic levels, and that the environment plays a central role in such analyses. Intended for graduate students and researchers, the book's emphasis is on assumptions and testing of models. Mathematical processes are described, but mathematical derivations are kept to a minimum. Each chapter includes a summary, and boxes provide supplementary material.
