Azospirillum-Plant Associations presents the most significant information from the vast body of scientific work that has accumulated as a result of nearly two decades of intensive research. It emphasizes advances that have occurred over the last six years, covering such topics as plant growth promotion, recognition and elicitation of plant responses by bacteria and the inoculant industry, the metabolism of production of plant growth promoting substances (phytohormones), and aerotaxis and poly-ß-hydroxybutyrate metabolism.

Product Description
Medicinal plants and plant-derived medicine are widely used in traditional cultures all over the world and they are becoming increasingly popular in modern society as natural alternatives to synthetic chemicals. It is a fact that many cultures throughout the world still rely on indigenous medicinal plants for the primary health care needs. To date, 25% of modern medicines are derived from plants that have been used by traditional medical practitioners. The aim of this unique book is to provide scientific, technical and socio-economic data on ten medicinal plants that have been successfully commercialized in South and East Africa and which the authors believe offer considerable further scope for wealth creation and employment. These profiles provide concrete examples of the "green gold" that lies waiting to be developed in Southern Africa. This book will be of special interest to all those involved in the production and trade in botanical products, pharmaceutical, food supplement and cosmetic industries, plant conservation agencies, national and international plant research centers, Intellectual Property rights lawyers and organizations, university departments studying development, and all those interested in understanding the Convention on Biodiversity. ...

Product Description
Garden centres offer a wide selection of shrubs, but the information supplied with them is often scanty. It's easy to buy the wrong plant for the wrong situation. This guide provides information needed before buying a shrub: how big the plant will really grow; what soil it likes; whether it will flourish in shady conditions; how to prune it; what to look for to ensure the plant you buy is a healthy one; and what the different varieties look like. The book offers help in planning a border, or a whole garden, from scratch, and creating a scheme that has something of interest all year round. It contains a system of symbols and colour coding for identification of shrubs and their salient features. ... Read more

Inventing the Grand Canyon
Imagine being able to invent one of the great natural wonders of the world.This was practically the opportunity of the first park rangers to live at the canyon.Famous explorers and scientists had come and gone from the Grand Canyon and written their reports, but they seldomed stayed there any length of time.The rangers who came with the establishment of Grand Canyon National Park in 1919 were the first naturalists to live their lives there, and there was still plenty to explore, plenty of unknown geology, biology, and botany.Within a few years after 1919 these rangers were writing down their discoveries and experiences at the canyon, basically figuring out what this place was all about and how visitors could best experience it.1919 was also much closer to the age of Humboldt and Muir, when natural historians were adventurers and heroes and seers, expected to speak both science and poetry.The "notes" in this book are the record of those first park naturalists as they come to terms with a great natural wonder, and they are also notes in the sense of musical notes, a song of celebration.

The best of Grand Canyon Nature Notes 1926-1935
If you love the Grand Canyon, you will be delighted with this selection of naturalists articles written in the first half of the past century (!). Easy to read, most of the writing consisting of articles of a few lines to a few pages, you can open the book anywhere and transport yourself on or below the rim, at a time when a lot fewer tourists visited the canyon.The book is divided in three parts, Earth sciences (geology, river, sky and seasons), Life science (flora, fish, birds, mammals,) and Human history (archaeology, ethnobotany and history). Nice little B&W drawings throughout the book, this is a very good complement to a visit to the Grand Canyon or to any coffee table picture book on the Grand Canyon usually thin on writing. ...
