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 328 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 Sexual Selection written by Malte Andersson 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: 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.

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: Sperm Competition and Sexual Selection presents the intricate ways in which sperm compete to fertilize eggs and how this has prompted reinterpretations of breeding behavior. This book provides a theoretical framework for the study of sperm competition, which is a central part of sexual selection. It also discusses the roles of females and the relationships between paternal care in sperm competition.
