Biological Invasions in South Africa


Book Description

This open access volume presents a comprehensive account of all aspects of biological invasions in South Africa, where research has been conducted over more than three decades, and where bold initiatives have been implemented in attempts to control invasions and to reduce their ecological, economic and social effects. It covers a broad range of themes, including history, policy development and implementation, the status of invasions of animals and plants in terrestrial, marine and freshwater environments, the development of a robust ecological theory around biological invasions, the effectiveness of management interventions, and scenarios for the future. The South African situation stands out because of the remarkable diversity of the country, and the wide range of problems encountered in its varied ecosystems, which has resulted in a disproportionate investment into both research and management. The South African experience holds many lessons for other parts of the world, and this book should be of immense value to researchers, students, managers, and policy-makers who deal with biological invasions and ecosystem management and conservation in most other regions.

Orchid Biotechnology


Book Description

This book is an exposition of classical mechanics and relativity that addresses the question of whether it is possible to send probes to extrasolar systems. It examines largely well-understood physics to consider the possibility of exploring the nearby interstellar environment in a similar fashion to how the solar system has been explored. As such, this book is both a semipopularization of basic physics and an informal study of a likely future technological development. An auxilliary text on basic physics for students and laypersons as well as an illustration of the problems with interstellar exploration, this book is a must-read.
















Medicinal Plants of the World


Book Description

This publication provides a comprehensive and scientifically accurate guide to the best-known and most important medicinal plants, including those of special commercial or historical interest.

Over 500 full-color photographs are included to assist in the identification of the plants.
