The second edition of Mycorrhiza falls into a time period of excep tionally rapid growth in mycorrhizal research. Therefore the edi tors have been most pleased with the decision of the Springer Verlag to revise the first edition and to incorporate the remarkable advances experienced in the mycorrhizal field. The pace of discovery has been particularly fast at the two poles of biological complexity, the molecular events leading to changes in growth and differentiation, as well as the factors regulating the structure and diversity of natural populations and communities. Therefore the most significant changes introduced in the new edition of this book are found within these topics. Not only were many chapters up dated, but also new chapters have replaced existing ones. The individual decisions have not been easy, since valuable contribu tions had to be sacrificed in favour of new aspects; but the authors hope that a highly topical new edition will be of greatest benefit for a rapidly expanding field of research. We welcome comments and critics from readers. Since it was possible again to find leading scientists as contribu tors, we are confident that this revised second edition will stimulate further progress and contribute to a deeper understanding of advances in the mycorrhizal field. We are grateful to the Springer Verlag, especially Dr. Dieter Czeschlik, for his continued interest and active help. Dr. Maja Hilber-Bodmer and Dr.

Results of regular monitoring of the species diversity and structure of plant communities is used by conservation biologists to help understand impacts of perturbations caused by humans and other environmental factors on ecosystems worldwide. Changes in plant communities can, for example, be a reflection of increased levels of pollution, a response to long-term climate change, or the result of shifts in land-use practices by the human population. This book presents a series of essays on the application of plant biodiversity monitoring and assessment to help prevent species extinction, ecosystem collapse, and solve problems in biodiversity conservation. It has been written by a large international team of researchers and uses case studies and examples from all over the world, and from a broad range of terrestrial and aquatic ecosystems. The book is aimed at any graduate students and researchers with a strong interest in plant biodiversity monitoring and assessment, plant community ecology, biodiversity conservation, and the environmental impacts of human activities on ecosystems.

In most breeding programs of plant and animal species, genetic data (such as data from field progeny tests) are used to rank parents and help choose candidates for selection. In general, all selection processes first rank the candidates using some function of the observed data and then choose as the selected portion those candidates with the largest (or smallest) values of that function. To make maximum progress from selection, it is necessary to use a function of the data that results in the candidates being ranked as closely as possible to the true (but always unknown) ranking. Very often the observed data on various candidates are messy and unbalanced and this complicates the process of developing precise and accurate rankings. For example, for any given candidate, there may be data on that candidate and its siblings growing in several field tests of different ages. Also, there may be performance data on siblings, ancestors or other relatives from greenhouse, laboratory or other field tests. In addition, data on different candidates may differ drastically in terms of quality and quantity available and may come from varied relatives. Genetic improvement programs which make most effective use of these varied, messy, unbalanced and ancestral data will maximize progress from all stages of selection. In this regard, there are two analytical techniques, best linear prediction (BLP) and best linear unbiased prediction (BLUP), which are quite well-suited to predicting genetic values from a wide variety of sources, ages, qualities and quantities of data.

Agroecosystems in a Changing Climate considers the consequences of changes in the atmosphere and climate on the integrity, stability, and productivity of agroecosystems. The book adopts a novel approach by bringing together theoretical contributions from ecologists and the applied interpretations of agriculturalists. Drawing these two approa
