Mahogany (Swietenia macrophylla) is one of the best-known and most valuable tropical timbers currently traded internationally. Concern has increased over the exploitation of mahogany, particularly as most timber is currently derived from natural forests which are not managed sustainably. Such concerns have resulted in an increased research effort focusing on the ecology of the species in natural forest. The potential of mahogany plantations as an alternative source of timber has received relatively little attention. However, evidence suggests mahogany may be a viable plantation species in many countries. The successful development of such plantations could make a major contribution towards meeting future demands for mahogany timber, and thereby help to reduce pressures on natural forest. The main aim of this book is to produce a comprehensive account of mahogany silviculture, with a particular emphasis on plantations, by bringing together the findings of foresters and researchers from mahogany-growing countries around the world. There is a logical progression through the stages of seed collection, plantation establishment, maintenance, prediction of growth and yield, protection and management of both natural stands and plantations under suitable silvicultural systems. This book is an indispensable guide and reference for those involved in growing and managing mahogany and will also be valuable to ecologists and land managers as well as students of forestry.

International concern over the threat to species and ecosystems caused by human activities is at an all time high, which may result in high costs to present and future generations. The economic costs and benefits associated with the conservation and sustainable use of genetic resources of actual or potential value for food and agriculture is largely unknown. Economic instruments that can encourage implementation of socially optimal genetic resource conservation strategies as well as the sharing of the real benefits and costs are a useful measurement tool. This book is an edited compilation of papers from the Symposium on the Economics of Valuation and Conservation of Genetic Resources for Agriculture held in Rome in May 1996. It addresses some of the key issues involved in the estimation of the economic value of conserving genetic resources for agriculture. It covers the modelling of the value of Plant Genetic Resources (PGRs), empirical studies of PGRs (including field diversity and yield vulnerability), seven empirical studies of PGR breeding values, property rights in PGRs and the implications of modern biotechnology methods for PGR values. The book will be essential reading for workers in agricultural economics, plant breeding and genetics, and biodiversity and conservation.

The tourism industry and the tourists it serves can exert major influences on host communities at a number of levels. On the one hand, tourism can preserve cultures, resurrect forgotten traditions and prevent cultural stagnation. On the other hand, tourism can challenge existing values, social norms, traditions and behaviour, and this can lead to situations of conflict. In extreme cases, resistance or violence can be the result. For the majority of the time, it would seem that as long as tourism delivers the economic and social benefits it frequently promises, problems are often tolerated and some measure of conflict is accepted. However, whenever tourism brings cultures together, whether freely or forced, a range of complex issues are invoked such as the nature of cultural identity, social and economic power relations, legal and moral rights and management responsibilities. This book examines the changing relationships between tourism and host cultures and explores the reasons why and how conflicts emerge, in a series of detailed case studies from many parts of the globe including the United Kingdom, the United States, Australia, New Zealand, Nepal, Tunisia, Spain, Peru, and Greece. Initiatives and good practices are highlighted whereby conflict can be replaced by consensus and situations improved through effective management. This book is essential reading for tourism industry professionals and students and researchers in anthropology, sociology and geography.

Forest is the natural vegetation of most of Europe. Although the majority has been destroyed by human activity over the centuries, a considerable amount remains and has been managed to varying degrees and for a wide variety of reasons. This has resulted in a large number of natural and semi-natural landscapes and habitat types over the region and a high diversity of plant and animal communities adapted to them. The growing interest in natural history and the environment in recent years has resulted in a greater demand for information on the complex ecological history of European forest. This book is unique in providing wide ranging and detailed case studies on specific aspects, including grazing, management practices and conservation and overviews, from recognised authorities, of the latest research on the ecological history of forests and woodland in Europe. It consists of selected papers given at an international conference of forest historians organised in association with the British Ecological Society and the International Union of Forest Research Organizations at Nottingham University in September 1996. Contributions come from the UK, Ireland, Scandinavia, the Low Countries, Germany, France, Spain, Italy and Turkey. This book is essential reading for ecologists, conservationists, landscape historians, foresters and geographers. It will also be of interest to advanced students in these areas.

Plant species which can accumulate high concentrations of heavy metals have been known for over one hundred years. However, until the last twenty years their potential went largely unnoticed by scientists. The term hyperaccumulation was first introduced by the author (and colleagues) in 1977. This renewed interest, together with heightened environmental awareness and the discovery of the phenomenon in many more species has since stimulated research into a number of novel scientific and commercial uses. This book brings together for the first time in one volume all the relevant ecological information on hyperaccumulators and describes the new disciplines, methods and uses for them which continue to be explored. These include the removal of heavy metal pollutants from soils and waters (phytoremediation), the identification of ancient human settlements (phytoarchaeology), mineral exploration, the revegetation of degraded land and the exciting possibility of the commercial extraction of heavy metals from crop plants (phytomining). This book is essential reading for plant ecologists and physiologists who have an interest in hyperaccumulators, environmental consultants specialising in land restoration, and exploration geochemists. It will also be of great interest to professionals, lecturers and advanced students in environmental science, geology and soil science.

Lupins have until recently remained wild or semi-domesticated species of minor interest to agriculture, although their value as a rotation crop was noted 2,000 years ago. However, with the advent of the science of genetics in the early twentieth century, full domestication of Lupinus species for use as crops was begun, by the combination of favourable genes such as those for low alkaloid content, non-shattering pods and soft seeds. As a result several lupin species have become an important part of temperate farming systems as a high protein crop for both animal and human consumption. This book gives an authoritative account of the history, distribution and taxonomy of Lupinus species and the current knowledge of all aspects of their agronomy and impact on agriculture, including breeding, genetics and biotechnology, nutrition, nitrogen fixation, transport physiology, toxins, stress responses, pests and diseases, agronomy and farming systems, composition and food uses, economic value and trade. Contributions are made by researchers in Australia and Europe who have had key roles in lupin research. The book is essential reading for botanists, agronomists, plant breeders and geneticists involved with lupins and other grain legumes or with an interest in crop domestication and evolution. It also provides important information for lecturers and students of agriculture and for professionals in the livestock and food industries.

The development of computer simulation models is an important growth area in both pure and applied ecology. The opportunity that mathematical models provide to integrate the components of an ecosystem, results in the ability to make quantitative predictions about the future behaviour of that system, or of elements within it. This means that they are powerful tools with wide applications and enormous potential for increasing our understanding of natural systems and our ability to use them in a sustainable way. This book is, almost uniquely, a complete account of one such model, the Hurley Pasture Model, a dynamic, deterministic, mechanistic simulation model for grassland, which has been developed by the author over some twenty years, in collaboration with scientists at several centres. Firstly, the rationale and theoretical elements of this type of model are described. An overview of the Hurley grassland simulator and the derivation and construction of its plant, animal, soil and litter, water, and environment and management components is then given. Next, the model is evaluated by a series of long and short-term dynamic simulations and steady state responses, which demonstrate how predictions can be made about the effects of, for example, climate change or particular regimes of fertilizer application, grazing or cutting. This book will be of great value to grassland agronomists and modellers, crop physiologists and plant ecologists, and to students of ecology as a case study of a plant ecosystem model. It will also be of interest to other ecologists and environmentalists and those in the field of computer modelling and its applications.

This book describes the methodology for predicting the genetic merit of animals in the context of genetic improvement in an animal breeding programme. Information on an animal and its relatives, on either the characteristic to be improved or from other traits, can be used to predict the animal’s genetic merit, taking account of the relationships between measurements and the economic values of traits. The methodology is developed from first principles, without unnecessary detail or complexity, and all the required statistical and mathematical concepts are fully described in the book. The text discusses the methods for combining different sources of information and illustrates their use with examples of breeding programmes in cattle, sheep, pigs and poultry. A series of questions with detailed answers is included in the book, to help reinforce the ideas and provide some practical experience in the prediction of genetic merit. The text is aimed at final year undergraduate and first year postgraduate students of quantitative genetics and animal breeding.

Phosphorus is an essential element for plant growth and its input has long been recognised as necessary to maintain profitable crop production. However, phosphorus inputs can also increase the biological activity of surface waters and this can lead to the destruction of such aquatic ecosystems. Advanced eutrophication of surface water leads to problems with its use for fisheries, recreation, industry and drinking, due to the increased growth of undesirable algae and aquatic weeds, and oxygen shortages caused by their death and decomposition. It is therefore important to have a good understanding of the causes and mode of phosphorus loss from soil to water, to enable the problems to be controlled and managed. This book has been developed from an international workshop held in Ireland in late 1995. It is the first comprehensive consideration of the topic, and many leading researchers in the area have contributed to it. It is essential reading for all soil scientists and freshwater biologists, as well as for environmentalists, ecologists and agriculturalists concerned with sustainable land management and pollution. The book is also recommended to fisheries managers, fertilizer manufacturers and biologists working for water utilities.

Biological management of nutrient supply to plants is intrinsically more complex than the provision of nutrients as inorganic fertilizers. We need to know whether the nutrients released are retained or lost from the system, whether rates of decomposition can be manipulated to improve nutrient use efficiency, and how the various fractions of plant residues translate into pools of organic matter in soil. Only then can predictive models for nutrient release, plant uptake and soil organic matter dynamics be truly tested and validated. This book brings together contemporary ideas on the characterization and manipulation of plant quality and especially its role in soil organic matter formation and nutrient cycling. It contains work from the leading workers in both temperate and tropical systems. There are also contributions describing work outside decomposition in soil ecosystems, such as the work of plant biochemists and animal nutritionists, as research in these areas has provided many ideas and concepts used in plant quality analysis. A wide range of topics is covered from investigations at the molecular level through to management options for farmers in relation to optimising biological management of crop residues. The work presented in this volume is valuable to all those researching and managing the supply of nutrients to plants. It is important reading for soil scientists, plant physiologists and crop scientists.

Plants producing an aromatic oil, fruit, or seed have been used in religious ceremonies, for personal use and adornment, and for flavouring throughout history. There is now also world-wide pressure by consumers to use perceived natural compounds in edible and personal products. It is vital that producers should be able to service this growing demand efficiently, economically and above all reliably. Many essential oil crops are part of the economy of countries with expanding populations, resulting in increasing pressure on land to produce food and fuel. It is thus important to ensure the optimum social and economic benefit from establishing and growing essential oil crops. This book is concerned with growing essential oil plants profitably to obtain an aromatic derivative. Each chapter covers a different family. A brief history of the use and economic development is given, and cultivation, harvesting and distilling described. Results of current research and recommendations for improved agronomic practices, together with methods of adding value to the crop, such as producing honey or processing the oil, are also discussed.

This book is the third in a set of four providing a series on controlled reproduction in farm animals. The aim of the series is to provide a general review of the literature dealing with the different ways in which reproduction in the major farm mammals can be controlled and manipulated. The four volumes are effectively an expanded and new edition of a previous work, Controlled Breeding in Farm Animals (Pergamon Press, 1983). However, the literature on this subject has expanded so rapidly since the time of the earlier volume, that it is now thought appropriate to publish it in four separate volumes. Buffaloes, goats, deer and camelids have been added to the species covered by the series compared to the previous book. All volumes provide comprehensive reference lists and are fully up-to-date. This third volume focuses on pigs. It will appeal to reproductive physiologists and workers in animal production, animal breeding and veterinary medicine.

The first comprehensive monograph on periphyton, this book contains contributions by scientists from around the globe. Multi-disciplinary in nature, it covers both basic and applied aspects of periphyton, and is applicable worldwide in natural, extensive and intensive managed systems. Periphyton, as described in this book, refers to the entire complex of attached aquatic biota on submerged substrates, including associated non-attached organisms and detritus. Thus the periphyton community comprises bacteria, fungi, protozoa, algae, zooplankton and other invertebrates. Periphyton is important for various reasons: as a major contributor to carbon fixation and nutrient cycling in aquatic ecosystems; as an important source of food in aquatic systems; as an indicator of environmental change. It can also be managed to improve water quality in lakes and reservoirs; it can greatly increase aquaculture production; it can be used in waste water treatment. The book provides an international review of periphyton ecology, exploitation and management. The ecology part focuses on periphyton structure and function in natural systems. The exploitation part covers its nutritive qualities and utilization by organisms, particularly in aquaculture. The final part considers the use of periphyton for increasing aquatic production and its effects on water quality and animal health in culture systems. This book will help scientists and entrepreneurs further understand the ecology and production of aquatic systems and venture into new and promising areas.

Tourism, the world’s fastest growing industry, is now entering a more mature phase. During the 1970s and 1980s mass tourism, with its rigid, standardized packages, developed rapidly and provided many consumers with their first experiences of international travel. Today, a complex and multi-faceted industry, tourism faces growing pressures - consumer demand for more individually tailored holidays, an increasingly competitive operational environment, opportunities provided by new technology and growing environmental concerns. This book analyses the major challenges facing tourism today. The author highlights the central role of information technology in creating mass tourism by the mid-1970’s, and how this technology and innovation is creating a new “best practice” of flexibility, market segmentation and diagonal integration within tourism. The book demonstrates how companies in the industry can enhance their competitiveness in the market place. Aimed at both academics and industry practitioners, this original and challenging work will attract a wide readership.

This book is a product of the international VIDE (Virus Identification Data Exchange) project, which uses the DELTA (Description Language for Taxonomy) database system to collect diagnostic information on all plant viruses. Information on over 500 characters has been sought for each virus and stored in the VIDE database. Over two-thirds of these characters record the susceptibility, or otherwise, of a range of commonly used test plant species; the remainder represent the great range of other characters used for virus identification. Information on the known natural host range of each virus is also presented. The book covers more than 900 viruses, which represents the entire database of plant viruses from around the world. It includes all viruses of plants, not only those whose virions have been described, but also those such as umbraviruses that have no virion protein genes of their own, and use the virion proteins of their symbiotic helper viruses. Viroids and the many transmissible agents that cause virus-like diseases, but whose infectious particles have not yet been characterized, are excluded. However, the database accession numbers of the genomic sequences of satellite RNAs are included. The book also contains summaries of data for all the viruses that are definitive or tentative members of the 50 or so accepted genera or "groups". Overall, the book is a standard reference work that will prove indispensable for virologists ad plant pathologists.
