Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Derris Culture in Puerto Rico The growing of Derris elliptica: in Puerto Rico is described and dis cussed with some reference to cultural methods used in the Far East. The Sarawak Creeping and Changi No. 3 varieties are commercially superior to other selections of derris that have been tested. Unshaded nurseries, described in detail, have proved a practical means of rooting cuttings on a large scale. The use of rooted cuttings reduces the amount of weeding required and assures a more uniform stand of plants in the field. Simple methods of transplanting rooted cuttings and applying fertilizer are presented. Little is known of the fertilizer requirements of derris. Propagating material of commercial Size is used most efficiently at a field Spacing of 3 by 3 feet, but weeding costs are reduced by closer Spacing. Large cuttings produce plants that cover the soil more quickly and yield more roots per acre than small cuttings. Trellising the vines increased the yield of roots 75 percent and the number of cuttings 300 percent over those not trellised, but the labor requirement for trellising may be correspondingly increased.

Book excerpt: Excerpt from Beyond the Melting Pot: The Negroes, Puerto Ricans, Jews, Italians, and Irish of New York City History, or perhaps historians, keep passing New York by. During the Civil War New York [state] pro vided the greatest number of soldiers, the greatest quantity of supplies, and the largest amount of money. In addition, New York's citizens paid the most taxes, bought the greatest number of war - bonds, and gave the most to relief organiza tions. 1 Yet it is recalled as a war between Yankees and Southerners. The Union preserved, the American mind roams westward with the cowboys, returning, if at all, to the Main Streets of the Midwest. The only New York image that has permanently impressed itself on the national mind is that of Wall Street - a street on which nobody lives. Paris may be France, London may be England, but New York, we continue to reassure ourselves, is not America.

Book excerpt: In the tradition of Silent Spring, Raoul Robinson's Return to Resistance calls for a revolution. Traditional plant breeding techniques have led us to depend more and more on chemical pesticides to protect ourcrops. Return to Resistance shows gardeners, farmers, and plant breeders how to use a long-neglected technique to create hardy new plant varieties that are naturally resistant to pests and disease. Horizontal resistance breeding has been largely ignored in this century due to the popularity and apparent successes of the Mendelian geneticists. However the colossal, unrecognized failure of m.

Available in PDF, EPUB and Kindle. Book excerpt: The massive grasslands of Brazil -- known as the cerrados -- which cover roughly a quarter of its land surface and are among the most threatened regions in South America, have received little media attention. This book brings together leading researchers on the area to produce the first detailed account in English of the natural history and ecology of the cerrado/savanna ecosystem. Given their extent and threatened status, the richness of their flora and fauna, and the lack of familiarity with their unique ecology at the international level, the cerrados are badly in need of this important and timely work.

Available in PDF, EPUB and Kindle. Book excerpt: In recent years, tropical forests have received more attention and have been the subject of greater environmental concern than any other kind of vegetation. There is an increasing public awareness of the importance of these forests, not only as a diminishing source of countless products used by mankind, nor for their effects on soil stabilization and climate, but as unrivalled sources of what today we call biodiversity. Threats to the continued existence of the forests represent threats to tens of thousands of species of organisms, both plants and animals. It is all the more surprising, therefore, that there have been no major scientific accounts published in recent years since the classic handbook by Paul W. Richards, The Tropical Rain Forest in 1952. Some excellent popular accounts of tropical rain forests have been published including Paul Richard's The Life of the Jungle, and Catherine Caulfield's In the Rainforest and Jungles, edited by Edward Ayensu. There have been numerous, often conflicting, assessments of the rate of conversion of tropical forests to other uses and explanations of the underlying causes, and in 1978 UNESCO/UNEPI FAO published a massive report, The Tropical Rain Forest, which, although full of useful information, is highly selective and does not fully survey the enormous diversity of the forests.

Available in PDF, EPUB and Kindle. Book excerpt: Agroforestry in Sustainable Agricultural Systems examines the environmental and social conditions that affect the roles and performance of trees in field- and forest-based agricultural production systems. Various types of ecological settings for agroforestry are analyzed within temperate and tropical regions. The roles of soil, water, light, nutrient and pest management in mixed, annual, woody perennial and livestock systems are discussed. Important new case studies from around the world offer innovative strategies that have been used successfully in raising forests and tree products on a sustainable basis for commercial harvesting and for providing other environmental services in land conservation and watershed management.

This book was released on 2013-03-09 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mangrove, seagrass and coral reef ecosystems are of paramount ecological importance but have already undergone great degradation, which is advancing at an alarming rate. If present trends continue, the natural resource basis of the economy and ecology of tropical coastal regions will soon be ruined. This was the unanimous conclusion of the 110 scientists from 23 countries who gathered in Mombasa, Kenya, for a Symposium on the ecology of these ecosystems. Mangrove forest systems yield large amounts of fish, crabs, prawns and oysters. They are also valuable sources of fuelwood, timber, tannin and other natural products. Their non-marketable value is of equal importance: stabilization of the coastline, an indispensable nursery ground for numerous marine species with commercial value, a natural filter maintaining the clarity of nearshore water, a home for resident and migratory birds and other wildlife. Many of the true mangrove flora and fauna are now endangered by the clearing of the mangroves. It has been shown that in many countries between 25 and 100% of the mangrove forest has been destroyed alraedy in the last twenty years. The international scientific assembly concluded that much can be done to stop the degradation of these damaged ecosystems and to rehabilitate them. But new techniques must be found to use them on a sustainable basis for long-term economic return and for the well-being of coastal human settlements and a healthy environment.

Book excerpt: Ethnobotany: A Phytochemical Perspective explores the chemistry behind hundreds of plant medicines, dyes, fibers, flavors, poisons, insect repellants, and many other uses of botanicals. Bridging the gap between ethnobotany and chemistry, this book presents an introduction to botany, ethnobotany, and phytochemistry to clearly join these fields of study and highlight their importance in the discovery of botanical uses in modern industry and research. Part I. Ethnobotany, explores the history of plant exploration, current issues such as conservation and intellectual property rights, and a review of plant anatomy. An extensive section on plant taxonomy highlights particularly influential and economically important plants from across the plant kingdom. Part II. Phytochemistry, provides fundamentals of secondary metabolism, includes line drawings of biosynthetic pathways and chemical structures, and describes traditional and modern methods of plant extraction and analysis. The last section is devoted to the history of native plants and people and case studies on plants that changed the course of human history from five geographical regions: Africa, the Americas, Asia, Europe, and Ocean. Throughout the entire book, vivid color photographs bring science to life, capturing the essence of human botanical knowledge and the beauty of the plant kingdom.
