In this eloquent plea for compassion and respect for all species, journalist and gardener Nancy Lawson describes why and how to welcome wildlife to our backyards. Through engaging anecdotes and inspired advice, profiles of home gardeners throughout the country, and interviews with scientists and horticulturalists, Lawson applies the broader lessons of ecology to our own outdoor spaces. Detailed chapters address planting for wildlife by choosing native species; providing habitats that shelter baby animals, as well as birds, bees, and butterflies; creating safe zones in the garden; cohabiting with creatures often regarded as pests; letting nature be your garden designer; and encouraging natural processes and evolution in the garden. The Humane Gardener fills a unique niche in describing simple principles for both attracting wildlife and peacefully resolving conflicts with all the creatures that share our world.
Environmental toxicology is generally held to be the study of the potential of constituents of outdoor environments to impact either human health or the biological structure of the ecosystems involved. This volume is a first attempt to integrate toxicological studies of all of the many human environments, both indoor and outdoor, and their complex interrelationships. Included are considerations of natural environments, the agroecosystem, occupational, urban and domestic environments as well as the environment associated with Superfund sites and military deployments. The primary emphasis is on public health, including the potential health effects of toxicants found in different environments, the bioprocessing of such toxicants in humans and surrogate animals and the principles of risk analysis. Approaches the toxicology of human environments in a new and unique way, stressing the complex interrelationships of all human environments and the implication for human and environmental health Each chapter is written by an acknowledged expert and is addressed to those interested in the broader implications of the environmental modifications that are always associated with the activities of humans living and working in them

American Horticultural Society Book Award Winner: “An essential reference for all who wish to understand the science of the all-powerful weed.” —Better Homes and Gardens “What is a weed,” opined Emerson, “but a plant whose virtues have not yet been discovered?” While that may be a worthy notion in theory, these plants of undiscovered virtue cause endless hours of toil for backyard gardeners. Wherever they take root, weeds compete for resources, and most often win. They also wreak havoc on industry—from agriculture to golf courses to civic landscape projects, vast amounts of money are spent to eradicate these virile and versatile invaders. With so much at stake, reliable information on weeds and their characteristics is crucial. Richard Dickinson and France Royer shed light on this complex world with Weeds of North America. Organized by plant family, this encyclopedic volume features over five hundred species in two-page spreads with images and text identification keys. Species are arranged within family alphabetically by scientific name, and entries include vital information on seed viability and germination requirements. No matter what your philosophy on weeds, this guide provides much-needed background on these intrusive organisms. In the battle with weeds, knowledge truly is power, and Weeds of North America is perfect for gardeners, botanists, nature lovers, or anyone working in the business of weed ecology and control. “Royer’s photographs are almost perversely alluring. . . . How can you not be ensnared by a book populated by prostrate pigweed, tansy ragwort and dog-strangling vine?” —New York Times Book Review
The seminal text Plant Virology is now in its fifth edition. It has been 10 years since the publication of the fourth edition, during which there has been an explosion of conceptual and factual advances. The fifth edition of Plant Virology updates and revises many details of the previous edition while retaining the important earlier results that constitute the field's conceptual foundation. Revamped art, along with fully updated references and increased focus on molecular biology, transgenic resistance, aphid transmission, and new, cutting-edge topics, bring the volume up to date and maintain its value as an essential reference for researchers and students in the field. - Thumbnail sketches of each genera and family groups - Genome maps of all genera for which they are known - Genetic engineered resistance strategies for virus disease control - Latest understanding of virus interactions with plants, including gene silencing - Interactions between viruses and insect, fungal, and nematode vectors - Contains over 300 full-color illustrations
S2Pokeweed, a plant abundant in Appalachia, exhibits some chemical similarities to a related species that has shown molluscicidal properties. Because this suggests that pokeweed, Phytolacca americana L. (P. decandra L.), has potential for controlling fresh-water snails, we have compiled this report of its chemical composition, uses, propagation methods, and other potentially useful species of the genus Phytolacca. The related species, Phytolacca dodencandra L'Her, was found to be the source of a molluscicide, which could pIay an important role in control of bilharziasis, a parasitic disease of humans widespread in Puerto Rico, Africa, and other tropical areas (22). Dead snails and small fish were observed in waterways in areas of Ethiopia where people washed their clothes with this Phytolacca's fruit, which is rich in saponins. Some distance downstream and immediately upstream from the washing places, abundant live snails were present, suggesting that the fruit contained a toxin acting as a molluscicide. This was subsequently confirmed by laboratory tests; tap-water extracts of the dried and powdered fruit had an LC100 (lethal concentration) of 10 parts per million against snails (Biomphalaria, Bulinus: and Lymnea spp.) after 24-hour exposure at 23OC. Furthermore, it was shown that molluscicidal potency was not affected by the presence of soil or vegetable matter, an important factor when the molluscicide is used under natural conditions. S3.

Cell Biology and Immunology of Leukocyte Function is a collection of papers presented at the 12th International Leukocyte Culture Conference, held in Beersheba, Israel on June 1978. This book is organized into seven parts encompassing 111 chapters. The contributors cover the different aspects of cell biology and immunology and the unique leukocyte function. Part I describes the mechanism of lymphocyte activation, the structure and function of the plasma membrane, and the macromolecular synthesis during lymphocyte activation. This part also deals with the interaction of lymphocytes with mitogenic lectins, the comparison of the mitogenic and nonmitogenic lectin binding, and the role of macrophages in the response of lymphocytes to lectins. Part II explores the thymic factors and the development of characteristic markers, antigens, and receptors. This part particularly emphasizes lymphocyte differentiation. Parts III and IV examine the genetic control and intercellular interactions involved in leukocyte function and the parameters of the immune response under in vitro conditions. Chapters on cytotoxicity, the mechanisms of phagocytic killing, autoimmunity, and the responses of leukocytes to tumor cells are included in these parts. Part V discusses the interactions of viruses and leukocytes and provides data on the physical mapping and analysis of sarcoma and leukemia viruses, while Part VI considers the application of leukocyte culture to problems of clinical medicine. Part VII involves the study of radiation effects, with an emphasis on the application of total lymphoid irradiation to the induction of transplantation tolerance. This part also looks into the role of the DNA repair process. Cell biologists, immunologists, and biomedical scientists and researchers will greatly benefit from this book.
