Book Description
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.

Book Description
Ask airline passengers what they see as they gaze out the window, and they will describe a fragmented landscape: a patchwork of desert, woodlands, farmlands, and developed neighborhoods. Once-contiguous forests are now subdivided; tallgrass prairies that extended for thousands of miles are now crisscrossed by highways and byways. Whether the result of naturally occurring environmental changes or the product of seemingly unchecked human development, fractured lands significantly impact the planet’s biological diversity. In Ecology of Fragmented Landscapes, Sharon K. Collinge defines fragmentation, explains its various causes, and suggests ways that we can put our lands back together. Researchers have been studying the ecological effects of dismantling nature for decades. In this book, Collinge evaluates this body of research, expertly synthesizing all that is known about the ecology of fragmented landscapes. Expanding on the traditional coverage of this topic, Collinge also discusses disease ecology, restoration, conservation, and planning. Not since Richard T. T. Forman's classic Land Mosaics has there been a more comprehensive examination of landscape fragmentation. Ecology of Fragmented Landscapes is critical reading for ecologists, conservation biologists, and students alike.

Book Description
Parasitoids lay their eggs on or in the bodies of other species of insect, and the parasitoid larvae develop by feeding on the host, causing its eventual death. Known for a long time to applied biologists for their importance in regulating the population densities of economic pests, parasitoids have recently proven to be valuable tools in testing many aspects of evolutionary theory. This book synthesizes the work of both schools of parasitoid biology and asks how a consideration of evolutionary biology can help us understand the behavior, ecology, and diversity of the approximately one to two million species of parasitoid found on earth. After a general introduction to parasitoid natural history and taxonomy, the first part of the book treats the different components of the reproductive strategy of parasitoids: searching for a host, host selection, clutch size, and the sex ratio. Subsequent chapters discuss pathogens and non-Mendelian genetic elements that affect sexual reproduction; evolutionary aspects of the physiological interactions between parasitoid and host; mating strategies; life history theory and community ecology. A special effort is made to discuss the theoretical background to the subject, but without the use of mathematics.

Book Description
A never-before-translated occult classic that brings the science of herbal medicine back to its Hermetic roots • Includes a large collection of recipes for spagyric medicines and quintessences, with detailed step-by-step instructions, adapted from celebrated spagyrists such as Paracelsus, Pseudo-Lull, Philipp Ulstad, and Nicaise Le Fèvre • Provides botanical and medicinal classifications of over 600 plant species along with their astral natures, elemental qualities, and planetary and zodiacal signatures • Explores advanced methods and techniques and shares the author’s secret formula for a universal circulatum First published in French in 1911, this practical guide to the art of spagyrics begins by outlining the ancient yet often forgotten Hermetic foundations of herbalism. Author Jean Mavéric provides botanical and medicinal classifications of over 600 plant species along with an in-depth study of their astral natures, elemental qualities, and planetary and zodiacal signatures as well as practical advice on the appropriate times to harvest plants and administer herbal remedies and quintessences. Reviewing the general principles and procedures of premodern chemistry, Mavéric then explores the secret doctrines and operations of the spagyric art. He offers a large collection of recipes for spagyric herbal preparations adapted from celebrated spagyrists such as Paracelsus, Pseudo-Lull, Philipp Ulstad, Jan Baptist van Helmont, Oswald Croll, and Nicaise Le Fèvre, providing detailed step-by-step instructions for a veritable pharmacopeia of spagyric extracts, tinctures, elixirs, liquors, oils, unguents, salts, aquae vitae, and quintessences. Mavéric also shares his intricate theory of astral medicine and advocates a seasonal “Hermetic diet” designed to keep the humors of the body in equilibrium and prevent the onset of illness. In the final section of the book, Mavéric focuses on the more advanced methods and techniques of Paracelsus, Helmont, and George Starkey, unraveling the mysteries of manufacturing alkalis, alkahests, and menstrua and divulging his own secret formula for a universal circulatum. Available now for the first time in English, this occult classic unveils the art of extracting spagyric essences to a modern audience while also bringing the science of herbal medicine back to its Hermetic roots.
