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 2014-09-03 with total page 375 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 Genotype-by-environment Interactions and Sexual Selection by : Fiona Caroline Ingleby

Available in PDF, EPUB and Kindle. Book excerpt: Genotype-by-environment interactions (G x Es) describe genetic variation for phenotypic plasticity, such that the relative performance of genotypes varies across environments. These interactions have been studied in the context of natural selection for decades, but research interest in the evolutionary consequences of G x Es in sexual traits is more recent. Theory suggests that G x Es in sexual traits could be of fundamental importance to the operation of sexual selection across heterogeneous environments, but empirical research lags behind the theory. In this thesis, I review the current literature on the role of G x Es in sexual selection and identify areas for further research. Using cuticular hydrocarbons (CHCs) in the fruit fly Drosophila simulans as a model system for sexual selection, I examine G x Es in trait expression and quantify the effect of these G x Es in terms of sexual signal reliability and the coevolution of male and female sexual traits. To do so, I use a combination of quantitative genetics and laboratory environmental manipulations. First, I demonstrate that male CHC profile is subject to sexual selection through female mate choice and find some variation in patterns of mate choice across diets and temperatures (Chapter 3). Next, I identify G x Es in male and female CHC expression across diets and temperatures, although G x Es in male CHC profile across temperatures are weak (Chapter 4). I find that G x Es in male CHC expression can cause sexual signal unreliability, as predicted by theory, since male CHCs do not reliably signal heritable aspects of male attractiveness across diets and temperatures (Chapter 5). I also find G x Es in some aspects of female mate choice across temperatures (Chapter 6). In spite of the evidence for signal unreliability and variation in female mate choice across environments, I show that the overall outcome of mate choice is unaffected by G x Es, such that the same male genotypes are attractive across diets and temperatures (Chapters 5 and 6). From my results, it seems likely that females assess male attractiveness based on multiple male sexual signals, so that whilst male CHCs influence mate choice, CHC profile does not necessarily correlate well with overall male attractiveness. I discuss the implications of these results for the evolution of sexual traits and the genetic covariance between male and female sexual traits across environments. The research in this thesis highlights the importance of multivariate studies of sexual selection across environments for a more complete understanding of the evolution of sexual traits.

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 Maternal Effects in Mammals by : Dario Maestripieri
Download or read book Maternal Effects in Mammals written by Dario Maestripieri and published by University of Chicago Press. This book was released on 2009-08-01 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evolutionary maternal effects occur whenever a mother’s phenotypic traits directly affect her offspring’s phenotype, independent of the offspring’s genotype. Some of the phenotypic traits that result in maternal effects have a genetic basis, whereas others are environmentally determined. For example, the size of a litter produced by a mammalian mother—a trait with a strong genetic basis—can affect the growth rate of her offspring, while a mother’s dominance rank—an environmentally determined trait—can affect the dominance rank of her offspring. The first volume published on the subject in more than a decade, Maternal Effects in Mammals reflects advances in genomic, ecological, and behavioral research, as well new understandings of the evolutionary interplay between mothers and their offspring. Dario Maestripieri and Jill M. Mateo bring together a learned group of contributors to synthesize the vast literature on a range of species, highlight evolutionary processes that were previously overlooked, and propose new avenues of research. Maternal Effects in Mammals will serve as the most comprehensive compendium on and stimulus for interdisciplinary treatments of mammalian maternal effects.

Book Synopsis Adaptation and Fitness in Animal Populations by : Julius van der Werf
Download or read book Adaptation and Fitness in Animal Populations written by Julius van der Werf and published by Springer Science & Business Media. This book was released on 2008-10-17 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fitness and adaptation are fundamental characteristics of plant and animal species, enabling them to survive in their environment and to adapt to the inevitable changes in this environment. This is true for both the genetic resources of natural ecosystems as well as those used in agricultural production. Extensive genetic variation exists between varieties/breeds in a species and amongst individuals within breeds. This variation has developed over very long periods of time. A major ongoing challenge is how to best utilize this variation to meet short-term demands whilst also conserving it for longer-term possible use. Many animal breeding programs have led to increased performance for production traits but this has often been accompanied by reduced fitness. In addition, the global use of genetic resources prompts the question whether introduced genotypes are adapted to local production systems. Understanding the genetic nature of fitness and adaptation will enable us to better manage genetic resources allowing us to make efficient and sustainable decisions for the improvement or breeding of these resources. This book had an ambitious goal in bringing together a sample of the world’s leading scientists in animal breeding and evolutionary genetics to exchange knowledge to advance our understanding of these vital issues.
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
Download or read book Mate Choice written by Gil G. Rosenthal and published by Princeton University Press. This book was released on 2017-07-18 with total page 646 pages. Available in PDF, EPUB and Kindle. Book excerpt: A major new look at the evolution of mating decisions in organisms from protozoans to humans The popular consensus on mate choice has long been that females select mates likely to pass good genes to offspring. In Mate Choice, Gil Rosenthal overturns much of this conventional wisdom. Providing the first synthesis of the topic in more than three decades, and drawing from a wide range of fields, including animal behavior, evolutionary biology, social psychology, neuroscience, and economics, Rosenthal argues that "good genes" play a relatively minor role in shaping mate choice decisions and demonstrates how mate choice is influenced by genetic factors, environmental effects, and social interactions. Looking at diverse organisms, from protozoans to humans, Rosenthal explores how factors beyond the hunt for good genes combine to produce an endless array of preferences among species and individuals. He explains how mating decisions originate from structural constraints on perception and from nonsexual functions, and how single organisms benefit or lose from their choices. Both the origin of species and their fusion through hybridization are strongly influenced by direct selection on preferences in sexual and nonsexual contexts. Rosenthal broadens the traditional scope of mate choice research to encompass not just animal behavior and behavioral ecology but also neurobiology, the social sciences, and other areas. Focusing on mate choice mechanisms, rather than the traits they target, Mate Choice offers a groundbreaking perspective on the proximate and ultimate forces determining the evolutionary fate of species and populations.
Book Synopsis The Pied Flycatcher by : Arne Lundberg
Download or read book The Pied Flycatcher written by Arne Lundberg and published by A&C Black. This book was released on 2010-10-30 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Pied Flycatcher is one of Europe's best-studied species. The first detailed work on it was begun in the 1930s by German ornithologists, but it was Lars von Haartman's Finnish study that both established long-term research on the species and founded many of the central themes of modern ornithology. Soon after, in the late 1940s, Bruce Campbell set up an intensive project in southwest England, which also still runs to this day. Many other eminent ornithologists followed and in 1979 Arne Lundberg and Rauno Alatalo started their own work in Sweden, Finland and latterly the north of England. A Palaearctic migrant, the Pied Flycatcher is notable for its very variable male plumage and complex territorial and polygynous breeding system. They take readily to nest boxes and have provided excellent opportunities for the study of a wide range of biological problems. This broad review of the species provides not only a detailed biology of this fascinating little bird, but a commentary on many of the most interesting problems in bird behaviour and ecology. Illustrated by Tomas Part.
Book Synopsis Exposing Resource Allocation Trade-offs in Sexual Selection by : Md Rahman Rahman
Download or read book Exposing Resource Allocation Trade-offs in Sexual Selection written by Md Rahman Rahman and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: [Truncated] Environmental and ecological conditions shape the evolution of life history traits in many species. Among such factors, food quality or nutrition availability can play an important role in moderating an animal's life history traits. In particular, it has been argued that sexually selected traits should exhibit heightened condition dependence, and theory predicts that only the fittest males are able to acquire and allocate the resources required for their expression. Because male condition is dependent on resource allocation, condition dependence in sexual traits is expected to underlie trade-offs between reproduction and other life-history functions. My thesis works towards determining whether such trade-offs and resource availability influence the expression of precopulatory (sexual behaviour and sexual ornamentation) and postcopulatory traits (the quality, size and number of sperm) in the guppy Poecilia reticulata, a polyandrous live bearing freshwater fish. In addition to studying condition dependence in these sexual traits, I also explore their genetic basis under experimentally manipulated dietary conditions, thus enabling me to determine whether genotype-by-environment interactions underlie the expression of pre- and postcopulatory sexual traits in this model species in sexual selection. In my first experimental chapter (Chapter 2), I tested whether experimentally manipulating diet quality (carotenoid levels) and quantity (food levels) influences the expression of pre- and postcopulatory sexual traits. I also determined whether diet manipulation mediates relationships among these traits. The study revealed a significant effect of diet quantity on the expression of both pre- and postcopulatory male traits; diet-restricted males performed fewer sexual behaviours and exhibited significant reductions in colour ornamentation, sperm quality, sperm number, and sperm length than those fed ad libitum. However, contrary to expectation, the study revealed no significant effect of carotenoid manipulation on the expression of any of these traits, and no evidence for a trade-off in resource allocation between pre- and postcopulatory episodes of sexual selection. Thus, while this initial study failed to reveal evidence for the expected co-dependence of pre- and postcopulatory traits on dietary carotenoid levels, it nevertheless underscored the sensitivity of behavioural, ornamental, and ejaculate traits to dietary stress and corroborates prior evidence from guppies that male sexual traits are highly sensitive to levels of resource acquisition. Furthermore, this study emphasised the important role that condition dependence plays in maintaining the high variability in male sexual traits frequently reported in this species.
Book Synopsis Female Control by : William G. Eberhard
Download or read book Female Control written by William G. Eberhard and published by Princeton University Press. This book was released on 1996 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evidence from various fields indicates that such selectivity by females may be the norm rather than the exception. Because most postcopulatory competition among males for paternity is played out within the bodies of females, female behavior, morphology, and physiology probably often influence male success in these contests, Eberhard draws examples from a diversity of organisms, ranging from ctenophores to scorpions, nematodes to frogs, and crickets to humans.

Book Synopsis Next Steps for Functional Genomics by : National Academies of Sciences, Engineering, and Medicine
Download or read book Next Steps for Functional Genomics written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2020-12-18 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the holy grails in biology is the ability to predict functional characteristics from an organism's genetic sequence. Despite decades of research since the first sequencing of an organism in 1995, scientists still do not understand exactly how the information in genes is converted into an organism's phenotype, its physical characteristics. Functional genomics attempts to make use of the vast wealth of data from "-omics" screens and projects to describe gene and protein functions and interactions. A February 2020 workshop was held to determine research needs to advance the field of functional genomics over the next 10-20 years. Speakers and participants discussed goals, strategies, and technical needs to allow functional genomics to contribute to the advancement of basic knowledge and its applications that would benefit society. This publication summarizes the presentations and discussions from the workshop.

Book excerpt: Awarded Bookauthority's "Best Aquaculture Books of all Time" A comprehensive resource that covers all the aspects of sex control in aquaculture written by internationally-acclaimed scientists Comprehensive in scope, Sex Control in Aquaculture first explains the concepts and rationale for sex control in aquaculture, which serves different purposes. The most important are: to produce monosex stocks to rear only the fastest-growing sex in some species, to prevent precocious or uncontrolled reproduction in other species and to aid in broodstock management. The application of sex ratio manipulation for population control and invasive species management is also included. Next, this book provides detailed and updated information on the underlying genetic, epigenetic, endocrine and environmental mechanisms responsible for the establishment of the sexes, and explains chromosome set manipulation techniques, hybridization and the latest gene knockout approaches. Furthermore, the book offers detailed protocols and key summarizing information on how sex control is practiced worldwide in 35 major aquaculture species or groups, including fish and crustaceans, and puts the focus on its application in the aquaculture industry. With contributions from an international panel of leading scientists, Sex Control in Aquaculture will appeal to a large audience: aquaculture/fisheries professionals and students, scientists or biologists working with basic aspects of fish/shrimp biology, growth and reproductive endocrinology, genetics, molecular biology, evolutionary biology, and R&D managers and administrators. This text explores sex control technologies and monosex production of commercially-farmed fish and crustacean species that are highly in demand for aquaculture, to improve feed utilization efficiency, reduce energy consumption for reproduction and eliminate a series of problems caused by mixed sex rearing. Thus, this book: Contains contributions from an international panel of leading scientists and professionals in the field Provides comprehensive coverage of both established and new technologies to control sex ratios that are becoming more necessary to increase productivity in aquaculture Includes detailed coverage of the most effective sex control techniques used in the world's most important commercially-farmed species Sex Control in Aquaculture is the comprehensive resource for understanding the biological rationale, scientific principles and real-world practices in this exciting and expanding field.
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 2019-12-31 with total page 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.
