Mutualisms, interactions between two species that benefit both of them, have long captured the public imagination. Their influence transcends levels of biological organization from cells to populations, communities, and ecosystems. Mutualistic symbioses were crucial to the origin of eukaryotic cells, and perhaps to the invasion of land. Mutualisms occur in every terrestrial and aquatic habitat; indeed, ecologists now believe that almost every species on Earth is involved directly or indirectly in one or more of these interactions. Mutualisms are essential to the reproduction and survival of virtually all organisms, as well as to nutrient cycles in ecosystems. Furthermore, the key ecosystem services that mutualists provide mean that they are increasingly being considered as conservation priorities, ironically at the same time as the acute risks to their ecological and evolutionary persistence are increasingly being identified. This volume, the first general work on mutualism to appear in almost thirty years, provides a detailed and conceptually-oriented overview of the subject. Focusing on a range of ecological and evolutionary aspects over different scales (from individual to ecosystem), the chapters in this book provide expert coverage of our current understanding of mutualism whilst highlighting the most important questions that remain to be answered. In bringing together a diverse team of expert contributors, this novel text captures the excitement of a dynamic field that will help to define its future research agenda.

This is the fourth volume of a series devoted to providing a comprehensive review of the study of plant-eating insects, covering topics ranging from biochemistry to ecology and evolution. Volume IV examines the status of mutualism, using the fig-insect interaction; phytosterols as important components of adaptive syndromes in herbivorous insects; methods utilized by plant-eating insects to detect compounds that deter feeding, including the various codes and how and why they vary; and the nature and significance of extrafloral nectaries in plants. The book also covers the varied roles of quinolizidines in plants, in addition to reviewing the controversial arena of plant stress and insect performance. Insect-Plant Interactions, Volume IV, is an important reference work for entomologists, zoologists, ecologists, and other scientists involved in studies with insect-plant interactions.
