Identification of chemicals that affect the naturally occurring interactions be tween organisms requires sophisticated chemical techniques, such as those docu mented in volume 1, in combination with effective bioassays. Without an effective bioassay, the identification becomes akin to looking for a needle in a haystack, but without any idea of what a needle looks like. To a large extent serniochemical identifications must be driven by bioassays. The design of bioassays for use in chemical ecology is governed by the sometimes conflicting objectives of ecological relevance and the need for simplic ity. Bioassay design should be based on observations of the interactions between organisms in their natural context, a theme that appears throughout this volume. As a result, this volume is as much about ecology and behavior as it is about specific methods. It is impossible to design a relevant bioassay, whether it is simple or complex, without understanding at least the fundamentals of how chemical cues or signals mediate the interaction in nature. Thus, the development of bioassay methods must be driven by an understanding of ecology and a knowledge of the natural history of the organisms under study. Given such an understanding, it is often possible to design assays that are both ecologically relevant and easy to perform.

Allelochemicals play a great role in managed and natural ecosystems. Apart from plant growth, allelochemicals also may influence nutrient dynamics, mycorrhizae, soil chemical characteristics, and microbial ecology. Synergistic action of various factors may better explain plant growth and distribution in natural systems. The book emphasizes the role of allelochemicals in shaping the structure of plant communities in a broader ecological perspective. The book addresses the following questions: (1) How do allelochemicals influence different components of the ecosystem in terms of shaping community structure? (2) Why is it difficult to demonstrate interference by allelochemicals (i.e., allelopathy) in a natural system in its entirety? Despite a large amount of existing literature on allelopathy, why are ecologists still skeptical about the existence of allelopathy in nature? (3) Why are there only scarce data on aquatic ecosystems? (4) What role do allelochemicals play in microbial ecology?.....

The field of plant population ecology has advanced considerably in the last decade since the first edition was published. In particular there have been substantial and ongoing advances in statistics and modelling applications in population ecology, as well as an explosion of new techniques reflecting the availability of new technologies (e.g. affordable and accurate Global Positioning Systems) and advances in molecular biology. This new edition has been updated and revised with more recent examples replacing older ones where appropriate. The book's trademark question-driven approach has been maintained and some important topics such as the metapopulation concept which are missing entirely from the current edition are now included throughout the text.

Chemical ecology is the ecology of body odour. Every organism uses chemical information in intra- and inter-specific interactions. Animals emit chemicals to attract a mate or to prevent a competitor from mating with the partner they just mated with. Plants emit chemicals to recruit other organisms to take care of their sex life or to attract bodyguards to defend them against their enemies. Chemical cues mediate a whole gamut of interactions in plant and animal communities. Chemical cues are used to communicate, but can also be exploited in espionage or eavesdropping. To understand the ecology of chemical signalling in communities one needs to carry out manipulative experiments. Such experiments have been done throughout the last century. However, in recent years the degree of precision with which such experiments can be done has grown tremendously as a result of rapidly increasing knowledge at the molecular-genetic level. This opens exciting new avenues to chemical ecologists. The connection of molecular genetics to community ecology and ecosystem ecology provides novel tools to take up old questions that were often hard to answer. This book provides an overview of chemical ecology related to different ecosystems and an outlook at novel directions that can be taken in chemical ecology through a molecular-ecological or eco-genomic approach. The book addresses above- and belowground terrestrial systems as well as aquatic systems, and the organisms involved are micro- and macro-organisms, such as plants, arthropods and mammals. The scientific approach presented in this book is characteristic of modern biological research. The book will be useful for scientists and students interested in ecology in general as well as those working in the fields of molecular, chemical, behavioural, population or community ecology.

The interdisciplinary field of marine chemical ecology is an expanding and dynamic science. It is no surprise that the breadth of marine organisms studied expanded in concert with developments in underwater technology. With its up-to-date subject reviews by experts, Marine Chemical Ecology is the most current, comprehensive book on the subject. The book provides cellular, physiological, organismal, evolutionary, and applied perspectives creating a high-resolution snapshot of the field at the start of the 21st century. The introductory section provides a broad phylogenic overview of marine organic chemistry. With its emphasis on evolutionary, ecological, and biosynthetic considerations, it sets a foundation for the chapters that follow. The second section takes an organismal approach to understanding the role of secondary metabolites in mediating trophic interrelationships. Section three reviews cellular and physiological aspects of marine chemical ecology. The final section discusses practical applications. Fully detailed with figures, tables, and chemical structural diagrams, the book's coverage spans aspects of marine ecology from molecular to community levels, bridging diverse disciplines. Written by an international panel, Marine Chemical Ecology provides a conceptual synthesis and overview of the discipline. You get an integrated perspective of the current state of the field, and its future.
