Book Description
Polyphenols: Mechanisms of Action in Human Health and Disease, Second Edition describes the mechanisms of polyphenol antioxidant activities and their use in disease prevention. Chapters highlight the anti-inflammatory activity of polyphenols on key dendritic cells, how they modulate and suppress inflammation, and how they are inactivated or activated by metabolism in the gut and circulating blood. Polyphenols have proven effective for key health benefits, including bone health, organ health, cardiac and vascular conditions, absorption and metabolism, and cancer and diseases of the immune system. They are a unique group of phytochemicals that are present in all fruits, vegetables and other plant products. This very diverse and multi-functional group of active plant compounds contain powerful antioxidant properties and exhibit remarkable chemical, biological and physiological properties, including cancer prevention and cardio-protective activities. - Expands coverage on green tea, cocoa, wine, cumin and herbs - Outlines their chemical properties, bioavailability and metabolomics - Provides a self-teaching guide to learn the mechanisms of action and health benefits of polyphenols

Book Description
Ferns, collectively, represent an ancient species of vascular plant which has a direct connection to the beginning of life on Earth. Today they are valued for their ornamental appeal, environmental benefit or as sources of health benefiting metabolites. Current pteridology, the study of fern, encompasses a wide range of research activities including, but not limited to, plant physiology, stress tolerance, genetics and genomics. The goal of this book is to compile the most relevant research done with ferns during the last decade. It is organized into four parts: I, Biology and Biotechnology; II, Evolution and Conservation; III, Metabolism and Genetic Resources, and IV, Environment. Each section reveals the utilization of ferns as a tool to explore challenges unique to plant development and adaptation. This project represents our collective effort to raise the awareness of ferns as a model system to study higher plant functions. Among the distinctive features of our proposed book are: (i) a wide range of topics with contributing researchers from all around the world, and (ii) recent advances of theoretic and applied knowledge with implications to crop species of economic value.

Book Description
"With their team of contemporary scholars, the editors present a thorough coverage of fundamental topics necessary for obtaining an up-to-date understanding of the biology of ferns and lycophytes. The book is organized into major topics that build from the individual and its biochemistry and structure, to genetics and populations, to interactions among individuals and the conservation of species, and concludes with perspectives on evolutionary history and classification. Each chapter is organized to review past work, explore current questions, and suggest productive directions for continued discoveries about these fascinating groups of organisms. Written for upper undergraduates, graduates and academic researchers, Biology and Evolution of Ferns and Lycophytes fills a major gap in biological, organism-level, evolutionary literature by providing a review of the biology and evolution of this important group of vascular land plants."--NHBS Environment Bookstore.

Book Description
A comprehensive, richly illustrated photographic field guide to the ferns and lycophytes of the eastern United States and Canada This is a comprehensive photographic field guide to the ferns, spikemosses, clubmosses, and quillworts of eastern North America. Accessible yet scientifically accurate, the book will appeal to beginners and experts alike and enhance the field experience of any user. Keys, range maps, detailed color photographs, and facing-page species descriptions aid exploration and allow reliable identification of all 305 species found in the area covered by the book—the United States east of the Mississippi and contiguous Canada, except for extreme northern and northeastern Canada. An introduction provides an easy-to-understand overview of identifying characteristics, life cycles, and evolutionary history. Checklists allow readers to record species they have seen, in four subregions. Indexes feature a complete list of common and scientific names, including synonyms, ensuring that users can find the plants they are looking for and keep track of changes in taxonomy. In addition, information about hybrids, polyploids, and reticulate relationships is provided, illuminating the fascinating processes that have led to such a rich diversity of species. Modern and innovative, this is the definitive guide to the ferns and lycophytes of eastern North America. Covers all 305 species, belonging to 96 genera and 30 families Features detailed color photos of all species—and facing-page species descriptions Provides checklists for keeping track of species seen Includes common and scientific names and notable synonyms

Book Description
Ferns are representative of genetic inheritance of great value as they include species of ancient vascular plants, which have direct connection with the evolution of plant life on Earth. This volume brings a selection of chapters covering a range of themes on fern biology, its development and growth, useful protocols for propagation and conservation purposes, genetic diversity, as well as medicinal and environmental applications. The content is organized into four parts: Biotechnology of Ferns Propagation of Ferns Ferns in Medicines Environmental Regulation This wide spectrum of the contributions provides quick access to information on the enormous potential of this plant group. This book brings together most recent research work and novel techniques, which is far from the traditional perspective usually followed. It is of interest to teachers, researchers, and botanists. Also the book serves as additional reading material for undergraduate and graduate students of agriculture, botany, forestry, and ecology.

Book Description
This encyclopedia offers access to the diversity of ferns and seed plants, the most important groups of green land plants. Available information of general and systematic relevance is synthesized at the level of families. Evidence from virtually all disciplines important to modern taxonomy makes the work a most valuable source of reference not only for taxonomists, but for all who are interested in the various aspects of plant diversity. A revised classification includes a complete inventory of genera along with their diagnostic features, keys for identification, and references to the literature. The first volume deals with pteridophytes and gymnosperms.

Book Description
Fundamentals of Weed Science provides an introduction to the basic principles of weed science for undergraduate courses. It discusses several aspects of weed biology and control, and traces the history of herbicide development. The book begins with an introduction to weeds, covering their definition, characteristics, harmful aspects, and the cost of weed control. This is followed chapters on weed classification, the uses of weeds, weed biology, weed ecology, allelopathy, the significance of plant competition, weed management and control methods, and biological weed control. Later chapters deal with herbicidesthe most important weed control tools and the ones with the greatest potential for untoward effects. Students of weed science must understand herbicides and the factors governing their use as well as the potential for misuse. These chapters discuss chemical weed control, the properties and uses of herbicides, factors affecting herbicide performance, herbicide application, herbicide formulation, ecological impact of herbicides, pesticide registration and legislation, weed management systems, and the future of weed science.
