Book Description
This book maintains that higher plants manifest some degree of sexual selection, and it begins to build a framework that unifies many features of plant reproduction previously considered unrelated. Reviewing evidence for sexual selection in plants, the authors discuss possible male-female interactions, concluding with an extensive set of hypotheses for testing. Mechanisms that could be employed in sexual selection in plants include various cellular mechanisms, such as both nuclear and cytoplasmic genetics, B chromosomes, and paternal contributions to the zygote, as well as abortion, double fertilization, delayed fertilization, and certain forms of polyembryony. This study compares the consequences of these processes for the evolution of mate choice in "gymnosperms" and angiosperms.

Book Description
Our requirement for plant breeders to be successful has never been greater. However one views the forecasted numbers for future population growth we will need, in the immediate future, to be feeding, clothing and housing many more people than we do, inadequately, at present. Plant breeding represents the most valuable strategy in increasing our productivity in a way that is sustainable and environmentally sensitive. Plant breeding can rightly be considered as one of the oldest multidisciplin ary subjects that is known to humans. It was practised by people who first started to carry out a settled form of agriculture. The art, as it must have been at that stage, was applied without any formal underlying framework, but achieved dramatic results, as witnessed by the forms of cultivated plants we have today. We are now learning how to apply successfully the results of yet imperfect scientific knowledge. This knowledge is, however, rapidly develop ing, particularly in areas of tissue culture, biotechnology and molecular biology. Plant breeding's inherent multifaceted nature means that alongside obvious subject areas like genetics we also need to consider areas such as: statistics, physiology, plant pathology, entomology, biochemistry, weed science, quality, seed characteristics, reproductive biology, trial design, se lection and computing.

Book Description
A twenty-fifth anniversary edition of Charles Johnson’s National Book Award-winning masterpiece—"a novel in the tradition of Billy Budd and Moby-Dick…heroic in proportion…fiction that hooks the mind" (The New York Times Book Review)—now with a new introduction from Stanley Crouch. Rutherford Calhoun, a newly freed slave and irrepressible rogue, is lost in the underworld of 1830s New Orleans. Desperate to escape the city’s unscrupulous bill collectors and the pawing hands of a schoolteacher hellbent on marrying him, he jumps aboard the Republic, a slave ship en route to collect members of a legendary African tribe, the Allmuseri. Thus begins a voyage of metaphysical horror and human atrocity, a journey which challenges our notions of freedom, fate and how we live together. Peopled with vivid and unforgettable characters, nimble in its interplay of comedy and serious ideas, this dazzling modern classic is a perfect blend of the picaresque tale, historical romance, sea yarn, slave narrative and philosophical allegory. Now with a new introduction from renowned writer and critic Stanley Crouch, this twenty-fifth anniversary edition of Middle Passage celebrates a cornerstone of the American canon and the masterwork of one of its most important writers. "Long after we’d stopped believe in the great American novel, along comes a spellbinding adventure story that may be just that" (Chicago Tribune).

Book Description
Biochemistry: The Chemical Reactions of Living Cells is a well-integrated, up-to-date reference for basic chemistry and underlying biological phenomena. Biochemistry is a comprehensive account of the chemical basis of life, describing the amazingly complex structures of the compounds that make up cells, the forces that hold them together, and the chemical reactions that allow for recognition, signaling, and movement. This book contains information on the human body, its genome, and the action of muscles, eyes, and the brain. * Thousands of literature references provide introduction to current research as well as historical background * Contains twice the number of chapters of the first edition * Each chapter contains boxes of information on topics of general interest
