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.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Ecological Experiments stresses the importance to ecology of field experiments, where variables are manipulated in order to collect data on specific hypotheses, as opposed to the more passive observational method. The book begins by introducing a series of ecological questions that can be addressed experimentally for example, what is the significance of competition among species? The minimal requirements of experimental design that must be met are then introduced, together with examples of good and poor experiments from the ecological literature and a consideration of the trade-offs that may be forced on the experimenter by field conditions. All ecologists, and especially students beginning their careers in field study, will find in this text a good introduction to the experimental foundation of ecology.

Book excerpt: Recent Advances in Acarology, Volume I, emerged from the V International Congress of Acarology held at Michigan State University in August 1978. It includes the contents of the symposia and a selection of contributions to the workshops and submitted paper sessions. The book is organized into six parts. Part 1 focuses on the pest management of agricultural mites. Part 2 on the biology of spider mites presents contributions in the areas of male reproductive behavior, silk production, pheromones, the components of reproductive success, and the effects of nutrition and temperature on tetranychid development. Part 3 on stored product acarology includes papers that reflect a broad understanding of acarine biology, nutrition, biochemistry, systematics, and ecology. Part 4 is devoted to physiology, biochemistry, and toxicology. It includes reports on the use of low-energy laser-generated x rays to measure salt concentrations in ducts of living mites; the use of labeled butanediol in metabolism studies of acarid mites; and electron microscope studies of functional morphology of ticks. Part 5 on ecology, bionomics, and behavior includes studies on the developmental cycle of sponge-associated water mites; behavior of tick larvae in relation to C02; and the influence of maternal age on the sex ratio of the progeny of a tetranychid. Part 6 presents research on soil mite biology.

Download or read book Male Choice, Female Competition, and Female Ornaments in Sexual Selection written by Ingo Schlupp and published by Oxford University Press. This book was released on 2021 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: When Charles Darwin first proposed Sexual Selection Theory, he suggested two mechanisms: competition among males and choice by females. Although their importance is long established and extremely well understood, their mirror images have remained largely underappreciated; males also choose, and females also compete. The combination of male mate choice (MMC) and female competition (FC) may be one of the most overlooked yet important and intriguing phenomena in modern sexual selection theory. This novel text reviews our current understanding of MMC and FC, highlighting the important connections between them. It places both concepts in the context of related fields such as female choice, mating systems, and sexual selection theory more broadly. A truly holistic approach is provided which takes all the relevant elements into consideration, especially the relative roles of MMC and FC, female ornamentation, their evolutionary consequences, and their genetic basis. Considering male mate choice and female competition in this way as effectively two sides of the same coin creates a powerful paradigm for a more complete understanding of sexual selection. Male Choice, Female Competition, and Female Ornaments in Sexual Selection will be suitable for both graduate students and researchers interested in sexual selection from an evolutionary, psychological, and anthropological perspective. It will also appeal to a broader audience of behavioural ecologists and evolutionary psychologists.

Download or read book Marmots written by David P. Barash and published by Stanford University Press. This book was released on 1989 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, based on over twenty years of study around the world, the author summarizes and synthesizes virtually everything that is known of the social behaviour and ecology of marmots. The organizing principle of the author's approach is evolution by natural selection - and thus, the degree to which the social behaviour of free-living animals can be interpreted as representing adaptations to particular environmental conditions. This book is essentially a single, widespread genus (genus Marmota comprising fourteen species found in North America and Eurasia. As such, it represents a productive union of theoretical insights from Darwinism and modern sociobiology, accompanied by a wealth of empirical data. Marmots are notable in that they constitute a relatively homogeneous group, made up of numerous species which greatly resemble each other. However, they occupy widely varying habitats - from temperate, lowland elevations to (more often) alpine meadows - and theory would predict behavioural adaptations to match their habitats.
