Articles in this volume analyze rapidly evolving approaches, many at the cusp of development, to research plant defense mechanisms, pathogen variability, and epidemiology. Jones and Jones focus on emerging patterns that key resistance genes encode or require leucine-rich repeat proteins. Holub and Beynon analyze associating host resistance specificity with a locus and whether a phenotype is due to single or multiple genes. Ashby combines biochemical, molecular, and classical plant pathology to analyze interactions and provide leads to novel control strategies. Heath and Skalamera question why fungal biotrophs form intracellular structures, the significance of ensuing cellular rearrangements and death of invaded resistant cells. Spencer-Phillips explores the roles of haustoria and intercellular hyphae in intercepting organic and inorganic nutrients from hosts. Chamberlain and Ingram compare pathogen asexual and sexual reproduction for generating genetic variation, physiological and fitness costs and trade-offs. Hardham and Hyde consider new knowledge of sporangiogenesis and zoospore production in oomycetes. Dewey et al. analyze recent advances in accurately enumerating pathogens in soil. Wistemeyer et al. consider opportunities for horizontal gene transfer amongst microbes and plants in soil. Irwin et al. discuss origins of genetic variationof Phytophthora pathogens of pasture legumes. Rodriguez and Redman show how prominent pathogens which also behave as endophytes or saprophytes may influence plant community structure and dynamics. Haubold and Rainey challenge us to consider geneticvariation in plant-colonizing bacterial populations. Milgroom and Fry demonstrate that the practical need to understand pathogen variation is the most significant application of population genetics to disease management.

This book contains papers on the topics of brought together wetland SCientists from all wetland ecology and management, most of continents and provided an opportunity to exchange valuable information on a variety of which were presented at the 2nd International Wetlands Conference in Trebon, Czechoslovakia aspects on the ecology and management of wetlands. (13-22 June 1984). The conference, hosted by the Hydrobotany Department of the Institute of Botany, was organized by the Czechoslovak This volume contains papers that represent aspects of wetland management. Like most Academy of Sciences and the International ecological topics, the papers clearly Wetlands Working Group of the International Association of Ecology (INTECOL) with demonstrate that the science of wetland management is not evenly developed around the cooperation from the SCOPE (SCientific Committee on Problems of the Environment) world. In some areas, wetlands have not even Working Group on Ecosystem Dynamics in been adequately described and there is little Freshwater Wetlands and Shallow Water Bodies, information about the impacts that man is UNESCO Man and the Biosphere (MAB) having on them. In other areas, information on Program, International Society for Ecological wetland ecology and management has developed Modelling, and the International Society for to the point where regulations and laws provide Limnology (SIL).

This text is intended for plant physiologists, molecular biologists, biochemists, biotechnologists, geneticists, horticulturalists, agromnomists and botanists, and upper-level undergraduate and graduate students in these disciplines. It integrates advances in the diverse and rapidly-expanding field of seed science, from ecological and demographic aspects of seed production, dispersal and germination, to the molecular biology of seed development. The book offers a broad, multidisciplinary approach that covers both theoretical and applied knowledge.

In the last two decades, research on plant life-histories has made impressive progress. Nevertheless, an up-to-date overview, covering all the main branches of plant life-history research, has been lacking. The purpose of the present volume is to fill this gap in the current ecological literature. The ten chapters cover a wide range of topics, including genetic variation in life-history traits, modularity, resource and sex allocation, effects of pathogens and herbivores on life-history traits, evolution of dispersal, senescence, and important methods used in plant life-history research (including demographic and optimality models, and game theory). All authors are leading experts in their fields, and the book is recommended as a textbook for undergraduate and graduate levels.
