Book Description
There is a growing need for appropriate management of aquatic plants in rivers and canals, lakes and reservoirs, and drainage channels and urban waterways. This management must be based on a sound knowledge of the ecology of freshwater plants, their distribution and the different forms of control available including chemical, physical, biological and biomanipulation. This series of papers from over 20 different countries was generated from the highly successful European Weed Research Society symposia on aquatic plant management, this being the ninth. The contributions provide a valuable insight into the complexities involved in managing aquatic systems, discuss state-of-the-art control techniques such as biomanipulation using fish and waterfowl and the use of straw, and deal with patterns of regrowth and recovery post-management. Careful consideration is given to the use of chemicals, a practice which has come under scrutiny in recent years. Underpinning the development of such control techniques is a growing body of knowledge relating to the biology and ecology of water plants, including growth responses under different trophic conditions, the impact of pollution, and aspects of photosynthesis. The authorship of the papers represents the collective wisdom of leading scientists and experts from fisheries agencies, river authorities, nature conservation agencies, the agrochemical industry and both governmental and non-governmental organisations.

Book Description
The impetus for this volume was the 2nd International Wetlands Conference which was held in June, 1984 at Trebon, Czechoslovakia. An overview of the worlds wetlands was one of the themes of the conference and it was decided that a useful follow-up would be a publication on the same topic. The initial goal was to cover as many of the worlds wetlands as possible in one volume and to have an emphasis on wetland ecology, biota, classification, and management. Individuals who made presentations at the Trebon confer ence were asked to prepare chapters and the editors also solicited other contributions. For a variety of reasons, the initial goal has been difficult to reach, especially coverage of the entire globe, and it has been necessary to publish the contributions in more than one volume. Volume 1 represents the com pletion of the first phase of the project and it covers most of the Western Hemisphere, Australia, most of Africa, the Indian subcontinent, the Mediter ranean region, and Papua New Guinea. Volume 2 will contain chapters on Western Europe, Northern Europe, Central Europe, most of northern and It is our hope that Volume western Asia, the Middle East, and Indonesia. 2 will appear in the near future and, if possible, a third volume will be published if authors can be secured to cover areas such as the Far East, other parts of the Indo-Pacific region, and New Zealand.

Book Description
In 1984 the OK Tedi Mining Company Limited began mining copper and gold mineralization from Mt. Fubilan, which is located at the headwaters of the OK Tedi. Subsequent mining in the region followed in 1990. Since this time there has been intense monitoring of the environment undertaken by those in the field in order to better understand the possible impact of mining. This book assembles and summarizes research spanning two decades undertaken by leading experts with firsthand experience. Much of this research is contained in internal company reports, giving the reader rare insight and firsthand knowledge. Documents physical and biologic change in a large tropical river system brought about largely by mining in an otherwise pristine environment This book brings together a broad rand of disciplines to provide a comprehensive overview of change in a complex and dynamical tropical river system based largely on previously unpublished company reports The book provides examples of state-of-the-art strategies and methodologies for monitoring environmental impact in a large river system

Book Description
This practical field guide describes and illustrates in colour 90 common and widespread wetland plants found in Queensland, and gives a distribution map for each species. To assist those readers who are keen to learn more, the book includes a series of keys to help identify those species that are not illustrated in the book but which may be encountered in the field. The keys also help to identify closely related species. There is also a glossary of technical terms. Creating artificial wetlands for the treatment of wastewater and rehabilitating wetland areas that have been disturbed by roads, bridges, mining, housing and other infrastructure developments requires the use of a range of plant species. Wetland Plants of Queensland is an invaluable resource for all those involved in the reclamation of wetlands or the treatment of wastewater, including farmers, environmentalists and all those with an interest in wetland revegetation.

Book Description
The aim of this book is to help students and others identify the terrestrial vascular plants on the small island of Motupore in Bootless Bay, Central Province, on the south coast of Papua New Guinea. We hope it will encourage further botanical and ecological studies on the island. Since the plants on Motupore are found elsewhere in the surroundings of Port Moresby, the book may be of some use as a general guide to the local flora. However, the flora of Motupore is much less diverse than that of similar vegetation types on the mainland, and a number of common trees are absent from the island.

Book Description
World Bank Discussion Paper No. 337. Draws on household survey data from 87 rural villages in Bangladesh to examine the contribution that government family planning programs, as well as other health care interventions, have made toward the recent reduction in fertility by increasing contraceptive use and reducing infant mortality. The paper suggests that the programs have been effective and finds that targeted credit program placement, such as the Grameen Bank and the Bangladesh Rural Advancement Committee (BRAC), contributed to the effort as well.

Book Description
This dictionary has been prepared primarily for professional botanists and for students of biology and forestry in Papua New Guinea. It is based on the "Dictionary of the Generic and Family Names of Flowering Plants and Ferns of the New Guinea and South-West Pacific Region (Botany Bulletin No. 3, March (1973)". It includes the genera found in Papua New Guinea with the islands, in West Papua (Irian Jaya) and in the Solomon Islands. Also included are introduced plant genera and those of economical importance. This book reprints the 1992 publication of the Wau Ecology Institute Handbook Number 13.
