This book brings together quantitative approaches used in the study of mechanisms of ruminant digestion and metabolism with the addition of five completely new chapters. Other chapters have been fully expanded and updated as appropriate and Dr Dijkstra has also been enrolled as the lead editor.

An understanding of plant diversity at both the genome and phenome level is important for both biodiversity conservation and plant breeding. This reviews aspects of plant evolution as it relates to variation in plant genomes and associated variations in plant phenomes.

Case study chapters are presented from Africa, Asia, the Caribbean, Latin America and Oceania. The book provides essential reading for advanced students and researchers in tourism and development studies.

Bringing together nutrition and immunology, Nutrition, Immunity and Infections covers the topic in an accessible format for all students of nutrition, medicine and public health.

Worldwide climatic changes have been raising concerns about potential changes to crop yields and production systems. Such concerns include the ability to accommodate these uncertain effects in order to ensure an adequate food supply for an increasing population.

This book provides the first coherent examination of the vast literature on the diversity of organisms that constitute the natural enemies of terrestrial molluscs. In a series of review chapters, it provides an authoritative synthesis of current research on predators, parasites and pathogens and how they might be used to control mollusc pests.

International Trade and Policies for Genetically Modified Products has been developed from the International Consortium on Agricultural Biotechnology Research. It covers five themes: analytical studies; empirical trade studies; spillover dimensions; intellectual property rights; and applied general equilibrium trade models.

Sustainable tourism is not a static target, but a dynamic process of change, a transition. This book considers how monitoring using indicators can assist tourism to make such a sustainability transition. It encourages the reader to view tourism from a broad, interdisciplinary perspective and draws on material from a wide range of sources.

This second edition has been thoroughly revised and updated to cover the major advances that have been made in the area in the last thirteen years. It has also been extended to examine the new commercial opportunities provided by biotechnology.

The demand for ecotourism and outdoor recreation is increasing, and the pressures on land use are becoming more obvious. A large part of the experience of ecotourism and recreational landscape depends on the maintenance of forested land. Effective management of tourism and recreation in forests can provide extra income to help offset the...

This volume considers ornamental bulbs, including the related storage organs of corms and tubers. An immense amount of research literature has been distilled, such that general principles are stressed throughout, but common examples are considered in some detail.
