Download or read book Polygyny and Sexual Selection in Red-Winged Blackbirds written by William A. Searcy and published by Princeton University Press. This book was released on 2014-07-14 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is to explain why red-winged blackbirds are polygynous and to describe the effects of this mating system on other aspects of the biology of the species. Polygyny is a mating system in which individual males form long-term mating relationships with more than one female at a time. The authors show that females choose to mate polygynously because there is little cost to sharing male parental care in this species, and because females gain protection against nest predation by nesting near other females. Polygyny has the effect of intensifying sexual selection on males by increasing the variance in mating success among males. For females, polygyny means that they will often share a male's territory with other females during the breeding season and will thus be forced to adapt to frequent female-female interactions. This work reviews the results of many studies by other researchers, as well as presenting the authors' own results. Studies of red-winged blackbirds have ranged from long-term investigations of reproductive success and demography, to research on genetic parentage based on modern molecular methods, to a variety of experimental manipulations of ecological circumstances and behavior. Since the red-winged blackbird is one of the best studied species of any taxa in terms of its behavior and ecology, the authors have a particularly extensive body of results on which to base their conclusions.

Download or read book Red-winged Blackbirds written by Les D. Beletsky and published by University of Chicago Press. This book was released on 1996 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drawing on detailed data from their sixteen-year study of red-winged blackbirds in the marshes of Washington's Columbia National Wildlife Refuge, Beletsky and Orians analyze the information redwings use to make breeding-season decisions and the consequences these decisions have for lifetime reproductive success. Because male and female redwings make different, and often independent, decisions—males focus on territory acquisition and maintenance, while females must choose when and where to nest and how much energy to invest in reproduction—the authors have taken the novel approach of studying the sexes separately. Using analyses of observational data combined with field experiments and game-theoretical models, the authors provide new insights into the complex patterns of reproductive decision-making and breeding behavior in redwings. This book will be of interest to all who study social animals, including behavioral ecologists, evolutionary biologists, and ornithologists.

Download or read book A Red Bird in a Brown Bag written by Geoffrey E. Hill and published by Oxford University Press. This book was released on 2002-09-26 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is an account of studies of the function and evolution of colorful plumage in the House Finch. It is also an engaging study on the evolution of sexual selection in birds and a lively portrait of the challenges and constraints of experimental design facing any field investigator working with animal behavior. Part I sets the stage for modern studies of the function of plumage coloration with a review of the nineteenth and beginning of the twentieth centuries. Part II focuses on the proximate control and present function of plumage coloration. Part III takes a more explicitly evolutionary approach to the study of plumage coloration using biogeography and phylogeny to test hypotheses for why specific forms of plumage color display have evolved. It concludes with an account of comparative studies that have been conducted in the House Finch and other cardueline finches and the insight these studies have provided on the evolution of carotenoid-based ornamental coloration.

Available in PDF, EPUB and Kindle. Book excerpt: What is responsible for the differences between the sexes in so many animals, from the brilliant plumage of birds of paradise to the antlers on deer? And why are the traits that distinguish the sexes sometimes apparently detrimental to survival? Even when they look more or less alike, why do males and females sometimes behave differently? Questions like these have intrigued scientists and the public alike for many years, and new discoveries are showing us both how wildly variable the natural world is, and how some basic principles can help explain much of that variation. Like natural selection, sexual selection is a process that results from differential representation of genes in successive generations. Under sexual selection, however, the crucial characteristics that determine whether an individual reproduces depend on sexual competition, rather than survival ability. This Very Short Introduction considers the history of our understanding of sexual selection, from Darwin's key insights to the modern day. Considering the investment animals place on reproduction, variation in mating systems, sexual conflict, and the origin of sexual dimorphism, Marlene Zuk and Leigh Simmons discuss questions such as whether females can really choose between males on aesthetic grounds, and how sexual conflict is resolved in different species. They conclude with a consideration of the thorny question of how, and even if, sexual selection theory applies to humans. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

This book was released on 2008-09-25 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research conducted in the last fifteen years has placed in question many of the traditional conclusions scholars have formed about human female sexuality. Though conventional wisdom asserts that women's estrus has been evolutionarily lost, Randy Thornhill and Steven W. Gangestad assert that it is present, though concealed. Women, they propose, therefore exhibit two sexualities each ovulatory cycle-estrus and sexuality outside of the estrous phase, extended sexuality-that possess distinct functions. Synthesizing research in behavioral evolution and comparative biology, the authors provide a new theoretical framework for understanding the evolution of human female sexuality, one that is rooted in female sexuality and phylogeny across all vertebrate animals.

Download or read book The Red-winged Blackbird written by Les Beletsky and published by . This book was released on 1996 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Red-winged Blackbird is not only one of North America's commonest birds, but also its best studied. It exemplifies the contribution that in-depth species studies can make to many of the central issues in behavioral ecology. In this book, Les Beletsky calls on 20 years experience of redwings to provide an up-to-date, comprehensive summary of all the major work done with these birds. These studies on the redwings' polygynous breeding system, strong territoriality, complex vocal communications, and broad distribution shed light on many themes of key interest to behaviorists and ecologists interested in the evolution of mate choice and species adaptations to habitats which vary in character in different parts of their range. An extra dimension is added in the consideration of redwings as pests, a widespread and often serious problem in crops of rice and corn. This book is written in an easy style, and will serve as an introduction, to both student and layperson, to redwings and what they can teach us of behavioral ecology. The Red-winged Blackbird provides the research worker with a balanced summary and comprehensive bibliography of one of ornithology's widest and deepest studies. Key Features * Covers perhaps the most studied bird in North America * Presents model species for studies in mating systems, habitat selection, vocal communication, and territorial behavior * Includes a comprehensive bibliography * Presented in an accessible style, ideal for student use

Available in PDF, EPUB and Kindle. Book excerpt: Bright colors, enlarged fins, feather plumes, song, horns, antlers, and tusks are often highly sex dimorphic. Why have males in many animals evolved more conspicuous ornaments, signals, and weapons than females? How can such traits evolve although they may reduce male survival? Such questions prompted Darwin's perhaps most scientifically controversial idea--the theory of sexual selection. It still challenges researchers today as they try to understand how competition for mates can favor the variety of sex-dimorphic traits. Reviewing theoretical and empirical work in this very active field, Malte Andersson, a leading contributor himself, provides a major up-to-date synthesis of sexual selection. The author describes the theory and its recent development; examines models, methods, and empirical tests; and identifies many unsolved problems. Among the topics discussed are the selection and evolution of mating preferences; relations between sexual selection and speciation; constraints on sexual selection; and sex differences in signals, body size, and weapons. The rapidly growing study of sexual selection in plants is also reviewed. This volume will interest students, teachers, and researchers in behavioral ecology and evolutionary biology.

Available in PDF, EPUB and Kindle. Book excerpt: Bird song, traditionally regarded as primarily a male trait, is in fact widespread among female songbirds and was probably present in the ancestor of modern songbirds (Odom et al 2014 Nature Communications). These recent findings challenge the view that sexual dimorphism in the expression and complexity of song is largely the outcome of sexual selection on males. It is now clear that understanding the evolution of bird song requires explaining variation within and among species in the expression and complexity of female song. To do this, we need a better understanding of the nature of variation in female song in different contexts and systems, as well as the fitness costs and benefits of variation in the expression and complexity of female song. This Research Topic draws together current research on female song with the goal of understanding the fitness costs and benefits of the diversity of female singing behaviour apparent among songbirds. It includes articles ranging from single-species studies investigating how female song varies with context and contrasts with male song, to comparative analyses exploring relationships between female song and ecological, social, and other factors, as well as opinion pieces.
