Until recently, the production of fruits by plants, their consumption by animals (frugivory) and the relevance of these to seed dispersal have attracted less attention than topics such as pollination biology. However, since the 1970s they have started to gain more prominence and now give rise to more research funding, seminal papers and international symposiums. This book contains chapters adapted from the Third International Symposium-Workshop on Frugivores and Seed Dispersal held in August 2000, in Rio Quente, Brazil.

Weaning represents a significant challenge to every young piglet and the success of the process is crucial to the lifetime performance of the animal. The transition from a liquid diet to one that is usually based on dry food ingredients is accompanied by major changes in digestive physiology, immune status and social and physical environments. Successful weaning is, therefore, the key to effective growth, feed efficiency and the subsequent development of the pig. This book has been developed from a British Society of Animal Science occasional meeting, held in September 2000. The Weaner...

Volunteer tourism describes a field of tourism in which travelers visit a destination and take part in projects in the local community. Projects are commonly nature-based, people-based or involve restoration of buildings and artifacts. Contemporary volunteer tourism has tended to suffer from a lack of differentiation from other forms of tourism or volunteering, falling into areas such as alternative tourism, international volunteering, social work and conservation corps work. The aim of this book is to provide it with a more specific identity. This book provides an overview of the phenomenon...

This book, in three volumes, presents a detailed revision of the systematics and taxonomy of the platyhelminth class Trematoda, subclasses Aspidogastrea and Digenea, with keys for the identification of these parasites at the superfamily, family, subfamily and generic levels.

The trematodes are parasitic worms infecting all vertebrate groups and include families of significance to human and animal health, with considerable economic impact. Volume 1 covers the subclass Aspidogastrea and order Strigeida, while the second and third volumes will cover...

Rapid urbanization has created a major challenge with regard to waste management and environmental protection. However, the problem can be ameliorated by turning organic waste into compost for use as an agricultural fertilizer in peri-urban areas. This is especially significant in less developed countries, where food security is also a key issue. This book addresses these subjects and is based on papers presented at a workshop held in Ghana by the International Board for Soil Research and Management (IBSRAM, now part of the International Water Management Institute) and FAO. Special reference...

Nematodes that are parasites of insects are no longer a laboratory curiosity. They have begun to be accepted as environmentally benign alternatives to the use of chemical insecticides, for the control of insect pests. Nematode worms are now applied as biological control agents against insect pests of numerous horticultural and agricultural crops. This book provides a comprehensive review of entomopathogenic nematology. It begins by reviewing fundamental biology and setting a taxonomic foundation for nematodes and their bacterial symbionts. Several chapters are devoted to functional processes...

Soil degradation and nutrient depletion have become serious threats to agricultural productivity in Africa. Soils cannot supply the quantities of nutrients required and yield levels decline rapidly once cropping commences. This book addresses these issues and includes papers from an international symposium held at Cotonou, Benin, October 9-12, 2000, organized by the International Institute of Tropical Agriculture, Ibadan, Nigeria and the Department of Land Management of the Katholieke Universiteit Leuven, Belgium. In five main parts, it marks the end of a first phase of collaborative research...

Genetically modified (GM) agricultural crops which are approved as safe in North America (Canada and the United States) are facing significant regulatory hurdles in gaining access to the European Union. The development and commercialization of GM crops illustrate a complex challenge facing trade diplomacy - the challenge of regulatory regionalism created by social regulatory barriers.

There is currently great concern about the sustainability of forestry and the contribution of private forestry towards this aim. The need to better understand the impact of different policy choices on private forestry has never been more important. This book includes a selection of peer-reviewed papers from a conference held in Atlanta in March 2001.

The global tourism industry continues a trend of sustained growth, moving more people and generating domestic and foreign revenues, often at the expense of the social and ecological integrity of destination regions. As a result, tourism policy makers have been forced to consider a variety of new approaches to ensure that the environment, local people, tourists, and business remain unaffected by the negative impacts of the industry.
