In 1980, the International Symposium on the Ecology of Bruchids Attacking Legumes (Pulses), organized by Dr. Labeyrie, was held at Tours, France. Since then, there has been tremendous progress in the area of Bruchid and Legume research. At the same time, as we face the problems of world-wide population explosion and food shortage, the importance of legumes as the world's major protein source is rapidly increasing, especial ly in tropical regions. Thus, it seemed appropriate to hold the Second Symposium in order to review the recent progress in the control of Bruchids and in the biology and ecology of Bruchids and legumes. This is an important part of the search for ways to integrate these fields with a common perspective. The Second International Symposium on Bruchids and Legumes (ISBL-II) was held in September 6-9, 1989 at Okayama, Japan under the joint auspices of the Japanese Society of Applied Entomology and Zoology and of the Foundation for Advancement of International Science. Significant contributions have originated in Japan on the study of Bruchid and legumes. Most notably, the study on population ecology by Professor S.

An excellent reference book for plant breeders and entomologists, Global Plant Genetic Resources for Insect-Resistant Crops combines germplasm preservation with use in insect-resistant crop development and basic research. The contributions of the authors represent the efforts, cooperation, and understanding of world leaders in the conservation and use of global plant genetic resources for sustainable agricultural production. Concepts addressed include dependency of modern agriculture on chemical pest control and applications of biotechnology in use of natural plant genes for insect-resistant crops.

This volume contains five papers dealing with a wide range of plant, animal, and soil biological topics.Gray and his colleagues describe the origin and spread of the salt marsh grass Spartina anglica. The result of a hybridization at the close of the last century, this genetically uniform species has been extremely successful in its particular niche and has a fascinating biology.Smith stresses the importance of gene-environment interactions in life-history theory in contrast to the resource constraint emphasis of the optimization approach. Experimental approaches to the subject are also discussed.Chanway and his colleagues examine the evidence for the importance of interactions between plants and micro-organisms in the rhizosphere in determining the outcome of plant competition and the establishment of community structure. Despite scarce evidence, real effects meriting further research do seem to exist.Brundrett also deals with an aspect of ecology in the soil. Most plants seem to have mycorrhizal associates and their importance is now widely appreciated. Much has been learned but more research is needed to determine the beneficial or after effects of mycorrhizae in natural systems.Richter and Babar review the diversity of tropical soils. They are in fact much more variable than is often thought, perhaps because too few ecologists are specialists in soils. Clearly, a proper knowledge and understanding of the many soil types is vital to conservation and development work in the tropics. - Serves as the fourth volume under new editorial direction - Presents a broad range of topical papers in ecology - Contains five papers dealing with a wide range of plant, animal, and soil biological topics

This new volume in the OSEB series presents reviews of key theoretical ideas and frameworks, and outlines progress in evolutionary studies.

Parasites have evolved numerous complex and fascinating ways of interacting with their hosts. The subject attracts the interest of numerous biologists from the perspective of ecology and behavioural biology, as well as from those concerned with more applied aspects of parasitology. However, until now there has been no recent book to synthesize this field.This book, written by leading authorities from the USA, Europe, Australia and New Zealand, provides the most comprehensive coverage of this important topic on the market.

The Asian beans and grams, the species of Vigna (subgenus Ceratotropis), include several legumes that are an essential component in the diets of a large proportion of Asia's population, and interest in these legumes is growing as ethnic cuisine spreads worldwide. However, this important group of legumes is little known compared to the closely related Phaseolus beans and soybean. That deficiency is addressed for the first time in this fully illustrated comprehensive conservation, genetics, taxonomic, and agricultural monograph on the genetic resources of the Asian Vigna. The book deals with the phylogeny of the group from the perspectives of morphological and molecular analyses, ex situ and in situ conservation, eco-geographical analyses, and research. In addition, morphological descriptions, keys, and eco-geographic details of each species in the group are provided. This genetic resources handbook and guide to the Asian Vigna will be a valuable reference for agriculturists, conservationists, taxonomists, other scientists, and students interested in the legumes and plant genetic resources.

Ecology, Genetics and Evolution of Metapopulations is acollection of specially commissioned articles that looks at fragmented habitats, bringing together recent theoretical advances and empirical studies applying the metapopulation approach. Several chapters closely integrate ecology with genetics and evolutionary biology, and others illustrate how metapopulation concepts and models can be applied to answer questions about conservation, epidemiology, and speciation. The extensive coverage of theory from highly regarded scientists and the many substantive applications in this one-of-a-kind work make it invaluable to graduate students and researchers in a wide range of disciplines. - Provides a comprehensive and authoritative account of all aspects of metapopulation biology, integrating ecology, genetics, and evolution - Developed by recognized experts, including Hanski who won the Balzan Prize for Ecological Sciences - Covers novel applications of the metapopulation approach to conservation
