The Mathematical Theory of Selection, Recombination, and Mutation R. Bürger University of Vienna, Austria "It is close to being a masterpiece…could well be the classic presentation of the area." Warren J. Ewens, University of Pennsylvania, USA Population genetics is concerned with the study of the genetic, ecological, and evolutionary factors that influence and change the genetic composition of populations. The emphasis here is on models that have a direct bearing on evolutionary quantitative genetics. Applications concerning the maintenance of genetic variation in quantitative traits and their dynamics under selection are treated in detail.

• Provides a unified, self-contained and in-depth study of the theory of mutilocus systems
• Introduces the basic population-genetic models
• Explores the dynamical and equilibrium properties of the distribution of quantitative traits under selection
• Summarizes important results from more demanding sections in a comprehensible way
• Employs a clear and logical presentation style

Explore the titillating world of gay male video pornography in One-Handed Histories: The Eroto-Politics of Gay Male Video Pornography. Author John Burger has compiled years of research on gay male films and videos and covers such interesting topics as: gay male porn history and theory pre-AIDS and post-AIDS awareness the portrayal of safe sex in videos popular memory gay history porn video productionBurger contends that gay male video pornography (GMVP) is "a warehouse of our cultural heritage and memory, as well as an important site for the production and modification of this heritage and memory." He looks at gay porn from social and historical perspectives, using popular memory as the starting point. As a form of popular memory, gay porn allows for numerous revisions and re-writings of American history, which has somewhat excluded gay men. One-Handed Histories assists the reader in placing GMVP in its correct social and historical setting and thus removes much of its stigma as obscene or useless. Gay scholars and even gay porn consumers will enjoy the alternative readings of these films; readings which might instill an interest and pride in gay male history. General gay male readers will discover in One-Handed Histories gay male sexual trends from the late 60s on and how this gay male history is documented by pornography.

The shimmering, cloud-covered planet of Venus conceals a wondrous secret: the strikingly beautiful yet deadly world of Amtor. In Amtor, cities of immortal beings flourish in giant trees reaching thousands of feet into the sky; ferocious beasts stalk the wilderness below; rare flashes of sunlight precipitate devastating storms; and the inhabitants believe their world is saucer-shaped with a fiery center and an icy rim. Stranded on Amtor after his spaceship crashes, astronaut Carson Napier is swept into a world where revolution is ripe, the love of a princess carries a dear price, and death can come as easily from the blade of a sword as from the ray of a futuristic gun."" "Pirates of Venus" is the exciting inaugural volume in the last series imagined and penned by Edgar Rice Burroughs. This commemorative edition features new illustrations by Thomas Floyd, the original frontispiece by J. Allen St. John, an afterword by Phillip Burger, a glossary of Amtor terms by Scott Tracy Griffin, a map of Amtor drawn by Edgar Rice Burroughs that appeared in the first edition, and an introduction by acclaimed science fiction and horror novelist F. Paul Wilson.

During a visit to the Holy City of Malacandra, Bernice Roberta Perchance learns that a sect of clerics wants to reform the church. On her return she writes a story about two detectives who must forge a semblance of a team, overcome insurmountable odds, and stop an assassination plot.

In this sequel to "At the Earth's Core," return to the world of Pellucidar--an exotic, savage land at the center of the Earth, an untamed wilderness where the sun never sets. When American explorer David Innes first discovered Pellucidar, he fell under the spell of the strange world, earning the respect of many, the undying hatred of a few, and the love of the beautiful Dian. Torn from her arms by trickery, Innes vows revenge and returns to the Inner World to seek his lost love. Innes breaks through the earth's outer crust, far from his beloved, and is forced to cross a fierce, unyielding world to reach her. Innes's epic journey through the many strange lands of Pellucidar, including the Land of Awful Shadow, which lies beneath the brilliantly conceived pendant moon, and his heart-pounding encounters with prehistoric beasts and strange peoples makes "Pellucidar" one of Edgar Rice Burroughs's most rousing adventures.

Five hundred miles beneath the earth's surface lies a fantastic, timeless world of eternal daylight, prehistoric beasts, and primeval peoples-Pellucidar. Pellucidar is a world within our world, a place where the horizon curves upward and merges with the sky. Here time stands still, for Pellucidar is illuminated by a miniature sun that never sets but hovers motionless in the sky. Scattered throughout the savage, prehistoric wilderness are communities of distrustful humans and the cities of the reptilian, highly evolved Mahars. David Innes and Abner Perry break through into this mysterious inner world. Their discovery of Pellucidar and the ensuing struggle to unite the human communities and overthrow the Mahars is a top-notch, thrilling tale of conquest, deceit, and wonder. This commemorative edition features an introduction by Gregory A. Benford and an afterword on the science of At the Earth's Core by Phillip R. Burger. Also included are a map of Pellucidar, a glossary of terms and names by Scott Tracy Griffin, a contemporary review, and the classic J. Allen St. John illustrations.
