Book Description
Tremendous progress has been made during the past decade in the burgeoning field of plant reproductive biology. A number of quantitative and technical breakthroughs, such as horizontal starch-gel electrophoresis, have resulted in a revolution in our thinking. The study of breeding systems, which used to be marked by a rather static focus on pollination and self-incompatibility, has been transformed by dynamic models of transitional pathways, and investigators are looking not only into genetic factors but ecological ones as well. Workers in the field have recently produced detailed accounts of mating success and the relative fitness of plants as male and female parents, thus testing the applicability of sexual selection theory to plants. Ecology and Evolution of Plant Reproduction surveys recent advances in the field of plant reproductive biology and identifies fruitful avenues for future research. The contributors are well known in the fields of morphology, systematics, genetics, cell biology, and ecology, representing the full spectrum of approaches that contribute vigor to this emerging field. This new work will benefit professionals and graduate students in plant science and plant breeding, evolutionary ecology, genetics, and reproductive biology.

Book Description
This book shares the latest insights into the genetic basis of molecular communication between plants and their microbial consortia. Further, the book highlights the capabilities of the rhizosphere and endosphere, which help manage ecosystem responses to climate change, nutrient cycling and sequestration of carbon; and discusses their application to the development and management of renewable energy sources. In their natural environments, plants are surrounded by a tremendous number of microorganisms. Some microbes directly interact with plants in a mutually beneficial fashion, while others colonize plants solely for their own advantage. In addition, microbes can indirectly affect plants by drastically altering their environments. Understanding the complex nature of the plant-microbe interface (PMI) can pave the way for novel strategies to improve plant productivity in an eco-friendly manner. The PMI approach focuses on understanding the physical, molecular, and chemical interactions between organisms in order to determine their functional roles in biological, physical, chemical and environmental systems. Although several metabolites from plants and microbes have now been fully characterized, their roles in chemical interactions between these associates remain poorly understood, and require further investigation.

Book Description
The medicinal properties of plants have been of interest to society for centuries and continue to be a subject of modern research. Yet too often research has been predicated upon poorly identified plant material and secondary sources of information. Much of what we know about the use of plants as drugs, poisons, foods, and as instruments of magical or religious practice derives from lore inherited from the clay tablets and papyri of the ancients and from compilations of early Greek, Arabic, and Indian physicians. Meanwhile, information pertaining to plant parts used even now in the daily life of peoples far removed from the influence of modern medical and health practices has been largely overlooked. With the encroachment of civilized cultures on primitive societies, unique traditions—often unwritten—are being destroyed. In many instances, the very plants involved are disappearing. Not infrequently, the only record, where one exists at all, of these vanishing pools of knowledge is that of the botanical field worker. For no matter what chemical or biological investigations may follow, the botanist can affix to an actual specimen, as he collects it in the field, the local terms applied to the plant and a description of native medicinal or other uses. Dr. Altschul has compiled field notes of health and medical interest on over 5,000 species of plants, culled from some 2,500,000 specimens of higher plants collected by field botanists from all over the world and deposited in the combined collections of the Arnold Arboretum and Gray Herbarium of Harvard University. The resulting catalogue represents a unique approach to supplying new investigational leads to researchers seeking biologically active plant principles. Dr. Altschul's meticulous sheet&ndashby–sheet examination of the Harvard collections provides the pharmacognosist, pharmacologist, and others in the medical and health sciences with an extensive firsthand survey of the domestic medicines of many cultures. These previously unpublished botanists' notes are here made available in a comprehensive publication that should become an important resource for every investigation into the area of medicinal phytochemistry. Indexes to families and genera are provided, as well as a medical index referring to diseases and to therapeutic properties for researchers intent on locating plants with special medicinal capacities. The author is a Research Fellow at the Botanical Museum of Harvard University.

Book Description
Twenty-two papers from the August 2000 conference in Berkeley discuss the biology and ecology of microorganisms associated with the aerial surface of plants. Covering the physical and chemical environment of plant surfaces, the interactions between epiphytes and their hosts, interactions between microbes, agricultural practices and food quality, and models of interactions and movement of microbes, the volume represents the work of plant pathologists, horticulturalists, ecologists, microbiologists, and other scientists from North America, Europe, Australia, Iran, and the Philippines.

Book Description
The vibrant history of the challenges and successes in the preservation of lands on and around Mt. Tamalpais, Marin County, California, and the key role of the Tamalpais Conservation Club played throughout the last 100 years. It is the history of how many key men and women, like William Kent and Alice Eastwood, and both public and private organizations came together for these efforts. This is the first time this has been documented in one book. This is as well a story of the birth of the environmental movement in the Western United States. The seeds were planted by earlier pioneering environmentalists such as President Theodore Roosevelt and John Muir, an honorary early TCC member. The book is rich with stories of people who made a difference through their passion and love for Mt. Tamalpais. The book, commemorating the TCC's 100th anniversary, includes narratives of the creation of the TCC, Muir Woods National Monument, Mt. Tamalpais State Park, Marin Municipal Water District, Golden Gate National Recreation Area (GGNRA), Marin County Open Space District, and other public areas on the mountain. Over 200 historic photos and documents are included.
