Book Description
Studies in floral biology are largely concerned with how flowers function to promote pollination and mating. The role of pollination in governing mating patterns in plant populations inextricably links the evolution of pollination and mating systems. Despite the close functional link between pollination and mating, research conducted for most of this century on these two fundamental aspects of plant reproduction has taken quite separate courses. This has resulted in suprisingly little cross-fertilization between the fields of pollination biology on the one hand and plant mating-system studies on the other. The separation of the two areas has largely resulted from the different backgrounds and approaches adopted by workers in these fields. Most pollination studies have been ecological in nature with a strong emphasis on field research and until recently few workers considered how the mechanics of pollen dispersal might influence mating patterns and individual plant fitness. In contrast, work on plant mating patterns has often been conducted in an ecological vacuum largely devoid of information on the environmental and demographic context in which mating occurs. Mating-system research has been dominated by population genetic and theoretical perspectives with surprisingly little consideration given to the proximate ecological factors responsible for causing a particular pattern of mating to occur.

Book Description
Yoko Ono created An Invisible Flower when she was just nineteen years old, at the very start of her artistic career. Recently rediscovered in her archive by her son, Sean Lennon, who also provides a foreword, this jewel of a book tells the heartwarming story of the invisible beauty we all know is there—and of the one man, "Smelty John", who catches sight of it. Written years before Ono met John Lennon, An Invisible Flower offers a glimpse into the early process of a brilliant conceptual artist and, it will transpire, presages the love of her life. Simple pastel drawings complement the book's affirming message, and a new afterword by Ono makes this small treasure even more special.

Book Description
These volumes are an exhaustive source of information on the control and regulation of flowering. They present data on the factors controlling flower induction and how they may be affected by climate and chemical treatments. For each plant, specific information is provided on all aspects of flower development, including sex expression, requirements for flowering initiation and development, photoperiod, light density, vernalization, and other temperature effects and interactions. Individual species are described from the standpoint of juvenility and maturation, morphology, induction and morphogenesis to anthesis. All information is presented alphabetically for easy reference

Book Description
For sample chapters, a video interview with David Hillis, and more information, visit www.whfreeman.com/hillispreview. Sinauer Associates and W.H. Freeman are proud to introduce Principles of Life. Written in the spirit of the reform movement that is reinvigorating the introductory majors course, Principles of Life cuts through the thicket of excessive detail and factual minutiae to focus on what matters most in the study of biology today. Students explore the most essential biological ideas and information in the context of the field’s defining experiments, and are actively engaged in analyzing research data. The result is a textbook that is hundreds of pages shorter (and significantly less expensive) than the current majors introductory books.

Book Description
Pollination is one of the most important processes in plant reproduction. It directly influences reproductive success and fitness and the genetic structure of the plant population. Methods exist to infer the pattern and distance of pollen dispersal, but direct observation of the movements of individual pollen grains during pollination is not feasible owing to their small size. Single-pollen genotyping is a novel technique for genotyping a single pollen grain. In this book, the principles, the experimental protocol, and several applications of this method in studies of plant ecology, reproductive biology, and evolutionary genetics have been described. More specifically, the information is useful for the analysis of linkage disequilibrium, intraspecific genetic variation, chromosome mapping, and the origins of polyploidy. It is also essential for achieving sustainable and optimal crop yield and is vital to agriculture and forestry. Written by pioneer researchers, the book provides novel research approaches that are proving useful in a growing number of fields. This volume is intended to encourage new and continued applications of single-pollen genotyping among many disciplines in the future.

Book Description
The first volume to address the study of evolutionary transitions in plants, Major Evolutionary Transitions in Flowering Plant Reproduction brings together compelling work from the three areas of significant innovation in plant biology: evolution and adaptation in flowers and pollination, mating patterns and gender strategies, and asexual reproduction and polyploidy. Spencer C. H. Barrett assembles here a distinguished group of authors who address evolutionary transitions using comparative and phylogenetic approaches, the tools of genomics, population genetics, and theoretical modeling, and through studies in development and field experiments in ecology. With special focus on evolutionary transitions and shifts in reproductive characters—key elements of biological diversification and research in evolutionary biology—Major Evolutionary Transitions in Flowering Plant Reproduction is the most up-to-date treatment of a fast-moving area of evolutionary biology and ecology.
