Book Description
The story of a nineteenth-century invention (essentially a tiny greenhouse) that allowed for the first time the movement of plants around the world, feeding new agricultural industries, the commercial nursery trade, botanic and private gardens, invasive species, imperialism, and more. Roses, jasmine, fuchsia, chrysanthemums, and rhododendrons bloom in gardens across the world, and yet many of the most common varieties have roots in Asia. How is this global flowering possible? In 1829, surgeon and amateur naturalist Nathaniel Bagshaw Ward placed soil, dried leaves, and the pupa of a sphinx moth into a sealed glass bottle, intending to observe the moth hatch. But when a fern and meadow grass sprouted from the soil, he accidentally discovered that plants enclosed in glass containers could survive for long periods without watering. After four years of experimentation in his London home, Ward created traveling glazed cases that would be able to transport plants around the world. Following a test run from London to Sydney, Ward was proven correct: the Wardian case was born, and the botanical makeup of the world’s flora was forever changed. In our technologically advanced and globalized contemporary world, it is easy to forget that not long ago it was extremely difficult to transfer plants from place to place, as they often died from mishandling, cold weather, and ocean salt spray. In this first book on the Wardian case, Luke Keogh leads us across centuries and seas to show that Ward’s invention spurred a revolution in the movement of plants—and that many of the repercussions of that revolution are still with us, from new industries to invasive plant species. From the early days of rubber, banana, tea, and cinchona cultivation—the last used in the production of the malaria drug quinine—to the collecting of beautiful and exotic flora like orchids in the first great greenhouses of the United States Botanic Garden in Washington, DC, and England’s Royal Botanic Gardens, Kew, the Wardian case transformed the world’s plant communities, fueled the commercial nursery trade and late nineteenth-century imperialism, and forever altered the global environment.

Book Description
Their natural enemies largely determine the population size and dynamic behavior of many plant-eating insects. Any reduction in enemy number can result in an insect outbreak. Applied biological control is thus one strategy for restoring functional biodiversity in many agroecosystems. Predators and Parasitoids addresses the role of natural enemies i

Book Description
This conference was organised by the Third World Academy of Sciences in collaboration with the Canadian International Development Agency. For the 250 female scientist participants from distant lands and diverse cultures from the Caribbean to the Far East, the conference proved a stimulating experience to recognize their strength in terms of numbers and achievements, to forge new links, nationally and internationally, and to demonstrate that science is independent of gender and is no longer an exclusively male-dominated preserve. The first part of the proceedings deals with the global, Third World and national perspectives of the theme “Women and Science” and the second highlights the scientific contributions by Third World women scientists, their personal experiences and scientific reports. The publication of these proceedings would serve as a potentially effective strategy aimed at enhancing the status of women scientists, not only in the Third World but worldwide.

Book Description
"There is nothing in the world like this book. It should be in every library and on the bookshelves of all those interested in cacti. The book will be an important resource for plant physiology, agronomy, and horticulture classes at both the undergraduate and graduate level."—Bruce Smith, Brigham Young University "Cacti: Biology and Uses is a landmark publication of one of the world's most unique group of plants. Park Nobel, a leading authority on succulent plants, has assembled a collection of contributions that spans a wide range of issues extending from basic systematics, anatomy, physiology and ecology to considerations of conservation and human uses of this diverse group of plants. This nicely-produced and well-illustrated volume provides a resource that will be of great use to a wide range of scientists, practitioners, and enthusiasts of this plant group."—Harold Mooney, Paul S. Achilles Professor of Environmental Biology, Stanford University
