Book Description
Sperm Competition and the Evolution of Animal Mating Systems describes the role of sperm competition in selection on a range of attributes from gamete morphology to species mating systems. This book is organized into 19 chapters and begins with the conceptualization of sperm competition as a subset of sexual selection and its implications for the insects. The following chapter describes the relationship between multiple mating and female fitness, with an emphasis on determining the conditions under which selection on females is likely to counteract selection on males for avoiding sperm competition. Other chapters consider the female perspective on sperm competition; the evolutionary causation at the level of the individual male gamete; and the correlation of high paternal investment and sperm precedence in the insects. The remaining chapters are arranged phylogenetically and explore the sperm competition in diverse animal taxa, such as the Drosophila, Lepidoptera, spiders, amphibians, and reptiles. These chapters also cover the evolution of direct versus indirect sperm transfer among the arachnids or the problem for kinship theory presented by multiple mating and sperm competition in the Hymenoptera. This book further discusses the remarkable potential for sperm competition among certain temperate bat species whose females store sperm through winter hibernation and the mixed strategies and male-caused female genital trauma as possible sperm competition adaptations in poeciliid fishes. The concluding chapter examines the predictions concerning testes size and mating systems in the primates and the possible role of sperm competition in human selection. This book is of great value to reproductive biologists and researchers.

Book Description
The ocean is filled with giant, strange, and scary creatures such as whales, octopuses, and sharks—but the prehistoric megalodon was powerful enough to crush a killer whale. Other sea beasts of the past could hold their own against even the most mysterious of modern sea creatures. Sea scorpions had claws the size of tennis rackets. Tanystropheus used its long neck to catch fish from land. And Leedsichthys had as many as 40,000 teeth! What would happen if these extinct beasts came to life? Imagine prehistoric sea beasts chasing dolphins, fighting crocodiles, and hunting humpback whales—and learn all about the prehistoric creatures of the deep!

Book Description
Selected from the country's leading literary journals and publications—Crazyhorse, Colorado Review, The Nervous Breakdown, Creative Nonfiction, Georgia Review, Gulf Coast, The Missouri Review, The Normal School, and others—Man in the Moon brings together essays in which sons, daughters, and fathers explore the elusive nature of this intimate relationship and find unique ways to frame and understand it: through astronomy, arachnology, storytelling, map-reading, television, puzzles, DNA, and so on. In the collection's title essay, Bill Capossere considers the inextricable link between his love of astronomy and memories of his father: "The man in the moon is no stranger to me,” he writes. "I have seen his face before, and it is my father's, and his father's, and my own.” Other essays include Dinty Moore's "Son of Mr. Green Jeans: A Meditation on Missing Fathers,” in which Moore lays out an alphabetic investigation of fathers from popular culture—Ward Cleaver, Jim Anderson, Ozzie Nelson—while ruminating on his own absent father and hesitation to become a father himself. In "Plot Variations,” Robin Black attempts to understand, through the lens of teaching fiction to creative writing students, her inability to attend her father's funeral. Deborah Thompson tries to reconcile her pride in her father's pioneering research in plastics and her concerns about their toxic environmental consequences in "When the Future Was Plastic.” At turns painfully familiar, comic, and heartbreaking, the essays in this collection also deliver moments of searing beauty and hard-earned wisdom.
