Book Description
A photographic guide to 536 species of plant galls found west of the Rockies Beautiful and bizarre, plant galls are growths of various shapes, sizes, and colors produced in response to invading organisms. Describing 536 species of galls and their causative agents, Plant Galls of the Western United States explores this unique realm with stunning photos and fascinating information about the life cycles of the organisms involved. Often species-specific, plant galls can be shaped like stars, baskets, clubs, wigs, bowls, and cups, with colors and combinations that stagger the imagination. This richly illustrated field guide examines how galls develop, and their uses, seasonal appearance and growth rate, predators, and defense mechanisms. The “architects” of galls—bacteria, fungi, mites, moths, beetles, flies, midges, and wasps—are explored in depth, and descriptions are paired with illustrations of these gall-inducing organisms and their typical galls. Gall accounts are divided into those that occur on trees, shrubs, and miscellaneous hosts, including native and ornamental plants. The guide contains a useful glossary and a bibliography. Features 536 gall species—including 120 new to science and 232 that have never appeared in a field guide before Examines for the first time more than 90 species from southwestern oak trees Contains more than 150 species from most of the deserts of the western states

Book Description
James H. Jones reveals in this biography that the public image of disinterested biologist, Alfred Kinsey, was in fact a carefully crafted persona. The Kinsey who emerges in these pages was a social reformer and a zealot, who devoted his every waking hour to the destruction of sexual repression.

Book Description
Alfred C. Kinsey's revolutionary studies of human sexual behavior are world-renowned. His meticulous methods of data collection, from comprehensive entomological assemblies to personal sex history interviews, raised the bar for empirical evidence to an entirely new level. In The Classification of Sex, Donna J. Drucker presents an original analysis of Kinsey's scientific career in order to uncover the roots of his research methods. She describes how his enduring interest as an entomologist and biologist in the compilation and organization of mass data sets structured each of his classification projects. As Drucker shows, Kinsey's lifelong mission was to find scientific truth in numbers and through observation—and to record without prejudice in the spirit of a true taxonomist. Kinsey's doctoral work included extensive research of the gall wasp, where he gathered and recorded variations in over six million specimens. His classification and reclassification of Cynips led to the speciation of the genus that remains today. During his graduate training, Kinsey developed a strong interest in evolution and the links between entomological and human behavior studies. In 1920, he joined Indiana University as a professor in zoology, and soon published an introductory text on biology, followed by a coauthored field guide to edible wild plants. In 1938, Kinsey began teaching a noncredit course on marriage, where he openly discussed sexual behavior and espoused equal opportunity for orgasmic satisfaction in marital relationships. Soon after, he began gathering case histories of sexual behavior. As a pioneer in the nascent field of sexology, Kinsey saw that the key to its cogency was grounded in observation combined with the collection and classification of mass data. To support the institutionalization of his work, he cofounded the Institute for Sex Research at Indiana University in 1947. He and his staff eventually conducted over eighteen thousand personal interviews about sexual behavior, and in 1948 he published Sexual Behavior in the Human Male, to be followed in 1953 by Sexual Behavior in the Human Female. As Drucker's study shows, Kinsey's scientific rigor and his early use of data recording methods and observational studies were unparalleled in his field. Those practices shaped his entire career and produced a wellspring of new information, whether he was studying gall wasp wings, writing biology textbooks, tracing patterns of evolution, or developing a universal theory of human sexuality.
