This collection of reviews by leading investigators examines plant reproduction and sexuality within a framework of evolutionary ecology, providing an up-to-date account of the field. The contributors discuss conceptual issues, showing the importance of sex allocation, sexual selection and inclusive fitness, and the dimensions of paternity and maternity in plants. The evolution, maintenance, and loss of self-incompatibility in plants, the nature of 'sex choice' in plants, and sex dimorphism are all explored in detail. Specific forms of biotic interactions shaping the evolution of plant reproductive strategy are discussed, and a taxonomically based review of the reproductive ecology of non-angiosperm plant groups, such as bryophytes, ferns, and algae, is presented. Together these studies focus on the complexities of plant life cycles and the distinctive reproductive biologies of these organisms, while showing the similarities between nonflowering plants and the more thoroughly documented flowering species.

The tobacco plant synthesizes nicotine to protect itself from herbivores. The female moth broadcasts sex pheromones to attract a mate, while a soldier ant deploys an alarm pheromone to call for help. The carbon dioxide on a mammal's breath beckons hungry ticks and mosquitoes, while a flower's fragrance speaks to the honey bee. Indeed, much of the communication that occurs within and between various species of organisms is done not by sight, sound, or touch, but with chemicals. From mating to parenting, foraging to self-defense, plant and animal activities are accomplished largely by the secretion or exchange of organic chemicals. The fascinating and fast-developing science that encompasses these diverse phenomena is introduced here, by William Agosta, in a series of remarkable stories absolutely accessible to the general reader yet revelatory to chemists and biologists. Among Agosta's characters are the organisms that steal, counterfeit, or interpret the chemical signals of other species for their own ends. We learn of seeds that mimic ant odors to facilitate their own dispersion and flies that follow the scent of truffles to lay their eggs. We read about pit vipers that react in terror when their flicking tongues detect a king snake, and slave-making ants incapable of finding their own food. And we meet ice-age people who ate birch fungus to relieve whipworms and early human hunters who used the urine of wolves to maneuver deer to favorable sites. Agosta also chronicles the rapid development of the applied science that makes use of chemical ecology. As researchers deepen our understanding of the biological world, they are making economically significant discoveries (such as enzymes that remain stable in extreme heat), finding ways to reduce our reliance on manufactured pesticides, identifying new uses for traditional medicines, and developing sophisticated new pharmaceuticals effective in treating malaria and several cancers. On the horizon are antiviral agents derived from the chemical defenses of marine species. From the exploits of flies to the high-stakes effort to cure human disease, Agosta's tour of chemical ecology grants any reader entrance to the invisible realm where chemistry determines life and death.

In the research on environmental hydraulics, its turbulence, and its sediment transport, constant challenges have been faced. The complexity of hydraulic impacts on sediment transport and turbulent flow properties makes research in this area a difficult task. However, due to pressure from climate change and the mounting issue of pollution, environmental flow studies are more crucial than ever. Bedforming within rivers is a complex process that can be influenced by the hydraulics, vegetated field, and various suspended and bedload transports. Changes in flow conditions due to rain and flood can further complicate a hydraulic system. To date, the turbulence, morphologic, and bedforming characteristics of natural environmental flows are still not well understood. This book aims to bring together a collection of state-of-the-art research and technologies to form a useful guide for the related research and engineering communities. It may be useful for authorities, researchers, and environmental, civil, and water engineers to understand the current state-of-the-art practices in environmental flow modelling, measurement, and management. It may also be a good resource for research, post-, or undergraduate students who wish to know about the most up-to-date knowledge in this field.

The authors bring you in this edited volume a collection of essays that address the relationship between racial violence, media, the criminal justice system, and education. This book is unique in that it brings together the perspectives of university professors, artists, poets, community activists, classroom teachers, and legal experts. With the Trayvon Martin murder and legal proceedings at the center of reflection and analysis, authors poignantly provide insight into how racial violence is institutionalized and consumed by the mass public. Authors borrow from educational theory, history, gender studies, sociology, cultural studies, the arts, legal scholarship, and personal reflection to begin the dialogue on how to move toward education for racial and social justice. The book is recommended for secondary educators, community organizers, undergraduate and graduate social science and education courses.
