The first volume of the Integrated Management of Plant Pests and Diseases book series presents general concepts on integrated pest and disease management, organized in three sections. Section one (modeling, management, environment) includes chapters on infection models, resurgence and replacement, plant disease epidemiology and effects of climate change in tropical environments. Followed by two reviews on IPM in post-harvest and carrot crops. The second section (emerging technologies) includes remote sensing and information technology, integrated by reviews on Bacillus thuringiensis and the role of mycorrhizae in IPM. In the third section (molecular aspects) the management of insect-borne viruses with transmission interference, some novel products for biological control and advances in molecular detection, are discussed.

The major objective of this book is to highlight the significance of phytonematodes in horticulture. Detailed and latest information on major aspects of phytonematodes associated exclusively with horticultural crops, which is the need of the day, is lacking. Hence, the book has been written mainly with the objective of providing its readers, comprehensive information on the advanced aspects related to phytonematodes associated with horticultural crops. It also provides basic information on plant parasitic nematodes since it is required for a better understanding of advanced topics. Several popular topics, information on which is already available in plenty, have been avoided. Thus, book explicates both the essential fundamental and advanced aspects pertaining to nematodes associated with horticultural crops. The book is conveniently divided into 13 chapters, which cover latest information on the major fundamental and advanced aspects related to phytonematodes including the role of phytonematodes in horticultural industry, phylogenetic and evolutionary concepts in nematodes, major phytonematodes associated with horticultural crops and their diagnostic keys, symptoms caused by phytonematodes and disease diagnosis, nematode population threshold levels, crop loss assessment, nematode diseases of horticultural crops and their management, nematode disease complexes, genetics of nematode parasitism, important nematological techniques and nematodes of quarantine importance. An exclusive chapter on novel methods of nematode management has been included mainly to provide the information on the latest molecules and novel modes of managing nematodes attacking horticultural crops. Routine nematode management aspects, information on which is already available, have not been discussed; instead, this topic reflects the changing scenario of future nematode management. Hence, this book can serve as a friendly guide to meet the requirements of the students, teachers and researchers interested in these 'hidden enemies' of the grower, apart from the research and extension personnel working under Public organizations, officials of State departments of Horticulture, Forestry, field workers and all those concerned and working with plant parasitic nematodes. Appropriate diagrams, convincing tables and suitable graphs/illustrations have been furnished at right places. A complete bibliography has also been included.

Increased atmospheric nitrogen deposition and changes in the management of heathlands have caused a significant change in the species composition of the NW-European heathlands. This change from ericaceous towards gramineous dominance is analysed in detail in Heathlands: Patterns and Processes in a Changing Environment. Special emphasis is put on the effects of increased atmospheric nutrient input on nutrient cycling, competition between plant species and plant--herbivore interactions. The possibilities for the long-term conservation of heathlands are discussed by considering regeneration from seed and the usefulness of mathematical management models. The book provides a synthesis of pure and applied plant ecology. It is vital reading for plant ecologists, biological conservationists, heathland managers and government decision makers.

As the demand for herbal medicines is increasing globally, the supply of medicinal plants is declining because most of this harvest is derived from wild and naturally growing resources. The genetic improvement of medicinal plants to produce higher yields and more active ingredients might help fulfil the increasing demand for medicinal plants. Medicinal plants are one of the most important sources of life-saving drugs for the world’s population. Increasing global demand for herbal medicines is accompanied by a dwindling supply of medicinal plants due to over-harvesting. Biotechnological interventions play a significant role in the improvement of crop yields and quality. Despite such progress in plant molecular biology, only limited biotechnology application has been seen in medicinal plants. Recent breakthroughs in high-throughput approaches have revolutionized this research area and shifted the focus towards omics approaches, such as genomics, transcriptomics, proteomics, and metabolomics. This book discusses these technologies. Currently, there is no existing publication that focuses on omics and medicinal plants.

Ecological biochemistry concerns the biochemistry of interactions between animals, plants and the environment, and includes such diverse subjects as plant adaptations to soil pollutants and the effects of plant toxins on herbivores. The intriguing dependence of the Monarch butterfly on its host plants is chosen as an example of plant-animal coevolution in action.
The ability to isolate trace amounts of a substance from plant tissues has led to a wealth of new research, and the fourth edition of this well-known text has consequently been extensively revised. New sections have been provided on the cost of chemical defence and on the release of predator-attracting volatiles from plants. New information has been included on cyanogenesis, the protective role of tannins in plants and the phenomenon of induced defence in plant leaves following herbivory.
Advanced level students and research workers aloke will find much of value in this comprehensive text, written by an acknowledged expert on this fascinating subject.

This timely reference provides an in-depth and up-to-date study of the most important groups of plant secondary compounds. No other work features such detailed diagrams of the biosynthetic pathways leading to the most important groups of secondary metabolites, as well as the structures of major types of compounds, their distribution in various taxonomic groupings of plants, and the evolutionary and ecological roles of these compounds. Plant Secondary Metabolism presents a basic understanding of the origin of the compounds, the nature of the precursors involved, and the basic reactions, mechanisms, and stereochemistry. The origin of groups of secondary metabolites is linked to evolutionary principles, and their biological activity is viewed in a context of chemical ecology. Topics are treated comprehensively, enabling the reader to understand not only a particular group of compounds, but also how each group fits into the whole. In addition, the text allows readers to systematically survey various secondary metabolites and gain a quick working knowledge which can be applied to problems in a particular field. Those researchers and students who will be most intrigued by this publication's broad overview on plant secondary metabolites come from a diverse range of disciplines, including agronomy, anthropology, biochemistry, biology, botany, chemistry, ecology, entomology, food science, forestry, geology, horticulture, pharmacognosy, plant biology, plant sciences, toxicology, and zoology.

Regional intercomparisons between ecosystems on different continents can be a powerful tool to better understand the ways in which ecosystems respond to global change. Large areas are often needed to characterize the causal mechanisms governing interactions between ecozones and their environments. Factors such as weather and climate patterns, land-ocean and land-atmosphere interactions all play important roles. As a result of the strong physical north-south symmetry between the western coasts of North and South America, the similarities in climate, coastal oceanography and physiography between these two regions have been extensively documented. High Latitude Rain Forests and Associated Ecosystems of the West Coast of the Americas presents current research on West Coast forest and river ecology, and compares ecosystems of the Pacific Northwest with those of South America.

Traditional plant physiological ecology is organism centered and provides a useful framework for understanding the interactions between plants and their environment and for identifying characteristics likely to result in plant success in a particular habitat. This book focuses on extending concepts from plant physiological ecology as a basis for understanding carbon, energy, and biogeochemical cycles at ecosystem, regional, and global levels.
This will be a valuable resource for researchers and graduate students in ecology, plant ecophysiology, ecosystem research, biometerology, earth system science, and remote sensing.

Natural and agro-ecosystems are frequently exposed to natural or synthetic substances, which, while they have no direct nutritional value or significance in metabolism, may negatively affect plant functioning. These, xenobiotics, may originate from both natural (fires, volcano eruptions, soil or rock erosion, biodegradation) and anthropogenic (air and soil pollution, herbicides) sources. And, while affected plants have only a limited number of possibilities for avoiding accumulation of these compounds, they do exhibit several enzymatic reactions for detoxification including oxidation, reduction, hydrolysis and conjugation reactions. In agro-ecosystems in particular these mechanisms have great significance in relation to herbicide detoxification and tolerance. In this volume an international group of experts present an overview of the nature and distribution of organic xenobiotics, including their uptake, effects on plant functioning and detoxification mechanisms. The particular significance of glutathione S-transferases in bio-indication and bio-monitoring, and in the detoxification of volatile organic air pollutants and herbicides is evaluated, and their potential significance in phytoremediation and bioaccumulation will be discussed. This volume will be of interest to a wide audience, from graduate students to senior researchers in a wide range of disciplines including plant ecology, plant biochemistry, agriculture and environmental management. It will also be of practical interest to environmentalists, policy makers and resource managers.

For investigators engaged in the study of toxins generally, and host-specific toxins in particular, it is a rare treat to attend a meeting in which toxins involved in plant pathogenesis are emphasized. A gathering of this type provides opportunity to consider the discovery of new toxins, their chemical structures, genes encoding enzymes that control their biosyntheses, their sites of action and physiological effects on plants, and their roles (if any) in pathological processes. Having acknowledged the inspiration fostered by a 'toxin meeting', however, it is important to point out that the program of this symposium was generously sprinkled with 'nontoxin' talks. These contributions generated cross-disciplinary discussion and promoted new ways of thinking about relationships among factors required for plant disease development. The point can be illustrated by considering just one example. We have in the past often regarded diseases mediated by host-specific toxins and diseases involving 'gene-for-gene' relationships as representing two different classes of fungal/plant interaction. This is largely because the key molecular recognition event in so-called 'toxin' diseases leads to compatibility, whereas the corresponding event in 'gene-for-gene' diseases leads to incompatibility. Yet the race specific elicitors produced by the 'gene-for-gene' fungi Cladosporium fulvum (De Wit, Adv. Bot. Res. 21:147- 185, 1995) and Rhynchosporium secalis (Rohe et a1. , EMBO J.

Annual desert plant species of unrelated taxa in the Negev Desert of Israel have developed complementary sets of adaptations and survival strategies as ecological equivalents with physiological, morphological and anatomical resemblances, in the various stages of their life cycles. After 40 years of research in hot deserts Yitzchak Gutterman provides a comprehensive treatise of such adaptations and strategies. In doing so he covers the following topics: post-maturation primary seed dormancy, which prevents germination of maturing seeds before the summer; seed dispersal mechanisms with escape or protection strategies; cautious or opportunistic germination strategies; seedling drought tolerance. The day-length is an important factor in regulating flowering as well as the phenotypic plasticity of seed germination which is also affected by maternal factors.

Forest vegetation is distributed in monsoon Asia continuously from boreal forests through temperate to tropical rain forests. This vegetation - the richest in the world - is being subjected to global change on an unprecedented scale. It has been predicted that boreal forests will experience the most significant change in response to global warming, while tropical forests are endangered by rapid changes in land use due to high population pressure. An increase in atmospheric CO2 concentration will severely affect ecosystem function in this area. This volume presents a review of terrestrial ecosystems in monsoon Asia and assesses possible effects of global change on the structure and function of forest ecosystems and feedback routes to the global carbon cycle. Audience: Vital reading for plant ecologists, vegetation scientists, environmental managers and government decision makers.

In response to low iron availability in the environment most microorganisms synthesize iron chelators, called siderophores. Bacteria and fungi produce a broad range of structurally diverse siderophores, which all show a very high affinity for ferric ions.

"Microbial Siderophores" presents an up-to-date overview of the chemistry, biology and biotechnology of these iron chelators. Following an introduction to the structure, functions and regulation of fungal siderophores, several chapters focus on siderophores of pseudomonads. Here, the technique of siderotyping, which has proved to be a rapid, accurate and inexpensive tool for pseudomonad characterization and identification, is described. Further, the biological significance of siderophores of symbiotic fungi and the possible role of siderophores in pathogenesis are discussed. In addition to methodological approaches, chapters on the biotechnological production of siderophores and their application in promoting human and plant health are included.

Origins of Plastids looks at symbiosis and symbiogenesis as a mechanism of evolution. This theory of endosymbiotic evolution postulates that photosynthetic prokaryotes living as endosymbionts within eukaryotic cells gradually evolved into the organelle structures called chloroplasts. The theory is controversial but has been strongly advocated by Lynn Margulis. Based on a colloquium held at the Bodega Bay Marine Laboratory of the University of California at Davis, Origins of Plastids reviews recent data on this most basic problem in plant evolution. In it, leading researchers in the field apply the theory of endosymbiotic evolution to plastid origins, producing an important new reference work for both professionals and graduates interested in the origins of life, the origins of the eukaryotic cell and its organelles, and the evolution of the higher plants in general. Origins of Plastids represents the state-of-the-art in its field. It should find a place on the bookshelves of people interested in microbiology, plant science, phycology, cell biology, and evolution.

The continuously growing human population along the world s coasts will exacerbate the impact of human activities on all coastal environments. Restoration activities will therefore become increasingly important. In particular, sandy shores and coastal dunes will require significant restoration efforts because they are preferred sites for human settlement, industrial and urban development and tourism.

With this book experts in the field present a comprehensive review of restoration studies and activities, where successful and failed studies or approaches from around the world are contrasted and compared. A major asset the book provides is a compendium of studies showing that coastal dune restoration has many definitions and thus leads to many different actions.

This volume addresses those with an interest in conservation ecology and biology, coastal dune dynamics and geomorphology, and coastal management who are seeking information on the different strategies for coastal dune restoration applied in different regions of the world. Finally, it will be a valuable resource for coastal scientists and planners, as well as for local and state officials, residents of coastal communities, environmental advocates and developers.
