Download or read book Sperm Competition and Its Evolutionary Consequences in the Insects written by Leigh W. Simmons 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: One hundred years after Darwin considered how sexual selection shapes the behavioral and morphological characteristics of males for acquiring mates, Parker realized that sexual selection continues after mating through sperm competition. Because females often mate with multiple males before producing offspring, selection favors adaptations that allow males to preempt sperm from previous males and to prevent their own sperm from preemption by future males. Since the 1970s, this area of research has seen exponential growth, and biologists now recognize sperm competition as an evolutionary force that drives such adaptations as mate guarding, genital morphology, and ejaculate chemistry across all animal taxa. The insects have been critical to this research, and they still offer the greatest potential to reveal fully the evolutionary consequences of sperm competition. This book analyzes and extends thirty years of theoretical and empirical work on insect sperm competition. It considers both male and female interests in sperm utilization and the sexual conflict that can arise when these differ. It covers the mechanics of sperm transfer and utilization, morphology, physiology, and behavior. Sperm competition is shown to have dramatic effects on adaptation in the context of reproduction as well as far-reaching ramifications on life-history evolution and speciation. Written by a top researcher in the field, this comprehensive, up-to-date review of the evolutionary causes and consequences of sperm competition in the insects will prove an invaluable reference for students and established researchers in behavioral ecology and evolutionary biology.

Book excerpt: This classic work on the rules of sex -- updated for a new generation -- is still as provocative as the day it was published, providing simple explanations for any and all questions about what happens in the bedroom. Sex isn't as complicated as we make it. In Sperm Wars, evolutionary biologist Robin Baker argues that every question about human sexuality can be explained by one simple thing: sperm warfare. In the interest of promoting competition between sperm to fertilize the same egg, evolution has built men to conquer and monopolize women while women are built to seek the best genetic input on offer from potential sexual partners. Baker reveals, through a series of provocative fictional scene, the far-reaching implications of sperm competition. 10% of children are not fathered by their "fathers;" over 99% of a man's sperm exists simply to fight off all other men's sperm; and a woman is far more likely to conceive through a casual fling than through sex with her regular partner. From infidelity, to homosexuality, to the female orgasm, Sperm Wars turns on every light in the bedroom. Now with new material reflecting the latest research on sperm warfare, this milestone of popular science will still surprise, entertain, and even shock.

This book was released on 2019-09-12 with total page 552 pages. Available in PDF, EPUB and Kindle. Book excerpt: The animals loosely termed fish constitute more than half of all known vertebrate species. There are approximately 27,000 described living species of bony fishes (Euteleostomi = Osteichthyes), about 70 species of hagfishes and some 34 species of lampreys. Approximately 970 species are chondrichthyans, the sharks and their relatives, which were the subject of volume 3 in this series. It is perhaps because fishes live in a buoyant medium, whether it be fresh or sea water, that they show a diversity in body shapes that is unparalleled by other vertebrates. There is also a unique diversity in the modes of reproduction, whether by external or internal fertilization, and this, with the morphology and fine structure of the reproductive system and its components, is the subject of Part A. Part B deals with complementary topics: testes, sperm, and sperm competition; endocrinology of reproduction; pheromones and reproduction; copulatory structures: taxonomic overview and the potential for sexual selection; sexual selection: signaling and courtship; adaptation and evolution of reproductive mode in copulating cottoid species; fertilization; sex determination; parental care; reproduction in relation to conservation and exploitation of marine fishes; Cryopreservation of Gametes; Embryogenesis and Development; and Molecular Genetics of Development.

Download or read book Alfred Bester s The Stars My Destination written by D. Harlan Wilson and published by Springer Nature. This book was released on 2022-04-25 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this comprehensive study of The Stars My Destination, D. Harlan Wilson makes a case for the continued significance of Alfred Bester’s SF masterwork, exploring its distinctive style, influences, intertextuality, affect, and innovation as well as its extensive metafictional properties. In Stars, Bester established himself as a son of the pulp-SF and high-modernist writers that preceded him and a forefather to the New Wave and cyberpunk movements that followed his lead. Wilson’s study depicts Bester as an SF insider as much as an outlier, writing in the spirit of the genre but breaking with the fixation on hard science in favor of psychological interiority, literary experimentation, and adult themes. The book combines close-readings of the novel with broader concerns about contemporary media, technoculture, and the current state of SF itself. In Wilson’s view, SF is a moribund artform, and Stars foresaw the inevitable science fictionalization of our benighted world. With scholarly lucidity and precision, Wilson shows us that Stars pointed the way to what we have (un)become.

Download or read book Lesbian Gay Bisexual and Transgender Americans at Risk written by Chuck Stewart and published by Bloomsbury Publishing USA. This book was released on 2018-02-16 with total page 932 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three volumes organized by the three phases of life—youth, middle age, and old age—explore the LGBTQ+ experience, delving deeply into research on a multitude of hot topics including risks experienced by this sometimes targeted population. In June of 2015, the United State Supreme Court issued an opinion that directly impacted the lives of many LGBT Americans: in Obergefell v. Hodges, the court required all states to issue marriage licenses to same-sex couples and to recognize same-sex marriages performed in other jurisdictions. While many activists consider this a major achievement, LGBT individuals still face a number of pressing issues. In Lesbian, Gay, Bisexual, and Transgender Americans at Risk, editor Chuck Stewart and a carefully selected group of contributors unravel these far-reaching concerns. The book is a cutting-edge resource for academics, activists, scholars, students, and lay people who are interested in examining LGBT social and political movements as well as the public policy progress and setbacks of recent years. Three volumes of essays by experts in a variety of fields delve deeply into primary sources to tackle important topics such as transgender adolescents, alcohol and drug abuse, and the massacre at Pulse gay nightclub, along with dozens of others. Organized by life stages, this comprehensive work sheds light on concerns and controversies affecting youth, adults, and seniors connected to the LGBT community

Download or read book Hearing Cultures written by Veit Erlmann and published by Routledge. This book was released on 2020-06-24 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vision is typically treated as the defining sense of the modern era and a powerful vehicle for colonial and postcolonial domination. This is in marked contrast to the almost total absence of accounts of hearing in larger cultural processes. Hearing Cultures is a timely examination of the elusive, often evocative, and sometimes cacophonous auditory sense - from the intersection of sound and modernity, through to the relationship between audio-technological advances and issues of personal and urban space. As cultures and communities grapple with the massive changes wrought by modernization and globalization, Hearing Cultures presents an important new approach to understanding our world. It answers such intriguing questions as: Did people in Shakespeare's time hear differently from us? In what way does technology affect our ears? Why do people in Egypt increasingly listen to taped religious sermons? Why did Enlightenment doctors believe that music was an essential cure? What happens acoustically in cross-cultural first encounters? Why do Runa Indians in the Amazon basin now consider onomatopoetic speech child's talk? The ear, as much as the eye, nose, mouth and hand, offers a way into experience. All five senses are instruments that record, interpret and engage with the world. This book shows how sound offers a refreshing new lens through which to examine culture and complex social issues.

Book excerpt: #5 in the Millennium SF Masterworks series, a library of the finest science fiction ever written. “Science fiction has only produced a few works of actual genius, and this is one of them.” —Joe Haldeman #5 in the Millennium SF Masterworks series, a library of the finest science fiction ever written. “Science fiction has only produced a few works of actual genius, and this is one of them.” —Joe Haldeman "Bester at the peak of his powers is, quite simply, unbeatable” —James Lovegrove Marooned in outer space after an attack on his ship, Nomad, Gulliver Foyle lives to obsessively pursue the crew of a rescue vessel that had intended to leave him to die. When it comes to pop culture, Alfred Bester (1913-1987) is something of an unsung hero. He wrote radio scripts, screenplays, and comic books (in which capacity he created the original Green Lantern Oath). But Bester is best known for his science-fiction novels, and The Stars My Destination may be his finest creation. With its sly potshotting at corporate skullduggery, The Stars My Destination seems utterly contemporary, and has maintained its status as an underground classic for fifty years. (Bester fans should also note that iBooks has reprinted ReDemolished, which won the very first Hugo Award in 1953.)
