Book Synopsis Sexual Segregation in Vertebrates by : Kathreen Ruckstuhl
Download or read book Sexual Segregation in Vertebrates written by Kathreen Ruckstuhl and published by Cambridge University Press. This book was released on 2006-01-05 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: Males and females often differ in developmental patterns, adult morphology, ecology and behaviour, and in many mammals males are often larger. Size dimorphism results in divergent nutritional and energetic requirements or reproductive strategies by the sexes, which in turn sometimes causes them to select different forage, use different habitats, and express differing social affinities. Such divergent life-styles often lead males and females to live large parts of their lives separately. Sexual segregation is widespread in animals. Males and females may share the same habitat, but at different times, for example, or they might use different habitats entirely. Why did sexual segregation evolve and what factors contribute to it? Sexual Segregation in Vertebrates explores these questions by looking at a wide range of vertebrates and is aimed as a synthesis of our current understanding and a guide for future research.

Book Synopsis Choosing Sexes by : Kristen J. Navara
Download or read book Choosing Sexes written by Kristen J. Navara and published by Springer. This book was released on 2018-02-01 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is extensive evidence that vertebrates of all classes have the ability to control the sexes of the offspring they produce. Despite dramatic differences in the mechanisms by which different taxa determine the initial sex of offspring, each group has found its own way of adjusting offspring sex ratios in response to social and environmental cues. For example, stress is a well-known modulator of offspring sex in members of all groups studied to date. Food availability, and limitation in particular, is another common cue that stimulates biases in offspring sex ratios in a wide variety of species. Offspring sex can be adjusted at the primary level, which occurs prior to conception, or at the secondary level, during embryonic development. While the mechanistic pathways that ultimately result in sex ratio biases and the developmental time-points sensitive to those mechanisms likely differ among taxa, the key involvement of steroid hormones in the process of sex ratio adjustment appears to be pervasive throughout. This book reviews the systems of sex determination at play in different vertebrate groups, summarizes the evidence that members of all vertebrate taxa can facultatively adjust offspring sex, and discusses when and how these adjustments can take place.
Book Synopsis Social Behavior of Female Vertebrates by : Samuel Wasser
Download or read book Social Behavior of Female Vertebrates written by Samuel Wasser and published by Elsevier. This book was released on 2012-12-02 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: Social Behavior of Female Vertebrates focuses on the evolution of reproductive behavior in female vertebrates ranging from fish to birds and humans, including issues of mate choice and other factors underlying female attitudes toward males. It also looks at the evolution of mating systems; the co-evolution of the sexes; sex-role reversal; reproductive competition between females; maternal behavior; and how females enhance the investment received by their offspring from others. It also considers other social behaviors that influence the nature of affiliative associations between females. Organized into three parts encompassing 13 chapters, this volume begins with an overview of behavioral biology and sources of variation in female reproductive success. It then discusses the establishment and maintenance of sex biases, sex differences mediated by sexual selection, constraints on female choice in the mottled sculpin, mate choice by females in sexual selection of bird song, and female manipulation of male avoidance of cuckoldry behavior in the ring dove. The reader is also introduced to the evolution of polyandry in shorebirds; reproductive strategies in human females; social and health-seeking behaviors of Taiwanese women; female roles in cooperatively breeding acorn woodpeckers; altruism in coati bands; cooperation and reproductive competition among female African elephants; mate choice in matrilineal macaque groups; and reproductive competition and cooperation among female yellow baboons. This book is a valuable resource for scientists and behavioral biologists, as well as lay people whose interests span a variety of fields.

Book Synopsis Sex Chromosomes and Sex Determination in Vertebrates by : Alberto J. Solari
Download or read book Sex Chromosomes and Sex Determination in Vertebrates written by Alberto J. Solari and published by CRC Press. This book was released on 1993-10-22 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: The cloning of the SRY gene and the attainment of XX mice transgenic for the Sry gene opened a new era in research on sex determination. This book surveys current knowledge of sex chromosomes and sex determination in all vertebrate classes, relying on the restriction of genetic recombination in sex chromosomes as the unifying concept of this subject. The book's interdisciplinary approach integrates contributions from the fields of cytogenetics, molecular biology, developmental biology, and evolutionary genetics. A detailed treatment of the meiotic behavior of sex chromosomes is featured, and the entire text is supplemented by numerous schemes, drawings, and electron micrographs. The book will be valuable to general cytogeneticists, vertebrate zoologists, and veterinarian and medical practitioners interested in the foundations of sex determination and the current knowledge of sex chromosomes. It will also interest students in advanced undergraduate and graduate courses in these areas.

Book Synopsis The Evolution of Beauty by : Richard O. Prum
Download or read book The Evolution of Beauty written by Richard O. Prum and published by Anchor. This book was released on 2017-05-09 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: A FINALIST FOR THE PULITZER PRIZE NAMED A BEST BOOK OF THE YEAR BY THE NEW YORK TIMES BOOK REVIEW, SMITHSONIAN, AND WALL STREET JOURNAL A major reimagining of how evolutionary forces work, revealing how mating preferences—what Darwin termed "the taste for the beautiful"—create the extraordinary range of ornament in the animal world. In the great halls of science, dogma holds that Darwin's theory of natural selection explains every branch on the tree of life: which species thrive, which wither away to extinction, and what features each evolves. But can adaptation by natural selection really account for everything we see in nature? Yale University ornithologist Richard Prum—reviving Darwin's own views—thinks not. Deep in tropical jungles around the world are birds with a dizzying array of appearances and mating displays: Club-winged Manakins who sing with their wings, Great Argus Pheasants who dazzle prospective mates with a four-foot-wide cone of feathers covered in golden 3D spheres, Red-capped Manakins who moonwalk. In thirty years of fieldwork, Prum has seen numerous display traits that seem disconnected from, if not outright contrary to, selection for individual survival. To explain this, he dusts off Darwin's long-neglected theory of sexual selection in which the act of choosing a mate for purely aesthetic reasons—for the mere pleasure of it—is an independent engine of evolutionary change. Mate choice can drive ornamental traits from the constraints of adaptive evolution, allowing them to grow ever more elaborate. It also sets the stakes for sexual conflict, in which the sexual autonomy of the female evolves in response to male sexual control. Most crucially, this framework provides important insights into the evolution of human sexuality, particularly the ways in which female preferences have changed male bodies, and even maleness itself, through evolutionary time. The Evolution of Beauty presents a unique scientific vision for how nature's splendor contributes to a more complete understanding of evolution and of ourselves.

Book Synopsis Sexual Reproduction in Animals and Plants by : Hitoshi Sawada
Download or read book Sexual Reproduction in Animals and Plants written by Hitoshi Sawada and published by Springer. This book was released on 2014-02-07 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the proceedings of the International Symposium on the Mechanisms of Sexual Reproduction in Animals and Plants, where many plant and animal reproductive biologists gathered to discuss their recent progress in investigating the shared mechanisms and factors involved in sexual reproduction. This now is the first book that reviews recent progress in almost all fields of plant and animal fertilization. It was recently reported that the self-sterile mechanism of a hermaphroditic marine invertebrate (ascidian) is very similar to the self-incompatibility system in flowering plants. It was also found that a male factor expressed in the sperm cells of flowering plants is involved in gamete fusion not only of plants but also of animals and parasites. These discoveries have led to the consideration that the core mechanisms or factors involved in sexual reproduction may be shared by animals, plants and unicellular organisms. This valuable book is highly useful for reproductive biologists as well as for biological scientists outside this field in understanding the current progress of reproductive biology.

Book Synopsis Induction and Segregation of the Vertebrate Cranial Placodes by : Byung-Yong Park
Download or read book Induction and Segregation of the Vertebrate Cranial Placodes written by Byung-Yong Park and published by Morgan & Claypool Publishers. This book was released on 2010 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: During evolution the vertebrate head has acquired a number of unique features including specialized paired sense organs and cranial sensory ganglia. These evolutionary novelties arise from discrete thickenings of the head ectoderm known as cranial placodes. They include the adenohypophyseal, olfactory, lens, trigeminal, profundal, otic, epibranchial and lateral line placodes. While distinct in the derivatives and cell types they will form, all cranial placodes originate from a common preplacodal domain surrounding the anterior neural plate. Recent evidence suggests that the induction of this pre-placodal domain and its subsequent subdivision into individual placodes with specific identities is a multi-step process. Here we describe the development of these placodes and their derivatives and summarize recent advances in the characterization of the repertoire of transcription factors underlying their development. We also review recent studies that have started to address the role of several classes of signaling molecules in placode induction and segregation, including Bone Morphogenetic Proteins, Fibroblast Growth Factors and Wnt molecules.
