Plants face a daunting array of creatures that eat them, bore into them, and otherwise use virtually every plant part for food, shelter, or both. But although plants cannot flee from their attackers, they are far from defenseless. In addition to adaptations like thorns, which may be produced in response to attack, plants actively alter their chemistry and physiology in response to damage. For instance, young potato plant leaves being eaten by potato beetles respond by producing chemicals that inhibit beetle digestive enzymes. Over the past fifteen years, research on these induced responses to herbivory has flourished, and here Richard Karban and Ian T. Baldwin present the first comprehensive evaluation and synthesis of this rapidly developing field. They provide state-of-the-discipline reviews and highlight areas where new research will be most productive. Their comprehensive overview will be welcomed by a wide variety of theoretical and applied researchers in ecology, evolutionary biology, plant biology, entomology, and agriculture.

Download and read online ebook Induced Plant Resistance to Herbivory write by Andreas Schaller. This book was released on 2008-03-27. Induced Plant Resistance to Herbivory available in PDF, EPUB and Kindle. This timely book provides an overview of the anatomical, chemical, and developmental features contributing to plant defense, with an emphasis on plant responses that are induced by wounding or herbivore attack. The book first introduces general concepts of direct and indirect defenses, followed by a focused review of the different resistance traits. Finally, signal perception and transduction mechanism for the activation of plant defense responses are discussed.

The Ecological Effects of Herbivore-specific Induced Plant Responses available in PDF, EPUB and Kindle. Feeding by herbivorous arthropods often induces phenotypic responses in their host plants. Such responses are increasingly found to be herbivore-specific, as both their strength and type can vary with herbivore identity. To date, most research has focused on discerning the causes, whether functional or evolutionary, of this specificity. However, recent studies have suggested that it can also have strong ecological effects on the distribution and occurrence of herbivores. Using Solanum dulcamara (bittersweet nightshade), I established a consistent ecological pattern within its herbivore community that is driven by specificity in plant responses: early-season differences in the identity of colonizing herbivores induce divergent plant phenotypes, producing heterogeneity in resource quality and a predictable distribution of late-season herbivores. These priority effects (i.e., differences in later herbivore occurrence caused by the identity of initial herbivores) seem to have their temporal basis in a physiological tradeoff within the plant, as it is unable to sequentially respond to different herbivore species. The responses associated with a particular herbivore occur only when it is the first species to feed on the plant. If its feeding follows that of a different herbivore, these responses are no longer induced. Chemical antagonism between different signaling pathways in the plant may underlie these results, in which case we may be able to predict the occurrence of priority effects based on knowledge of the response pathways induced by different herbivores. However, the spatial scale of these interactions can also influence their strength. I found that the presence of multiple plant phenotypes has a greater effect on herbivore occurrence within stands of S. dulcamara than it does between them. Fragmentation of S. dulcamara populations reduces the likelihood of herbivores moving between plants, thereby reducing the degree to which they can discriminate between different plant phenotypes. Overall, therefore, a combined knowledge of the chemical basis and ecological context of plant-herbivore interactions may be essential when examining the dynamics of herbivore communities.

Schowalter. This book was released on 2006-02-27. Insect Ecology available in PDF, EPUB and Kindle. Dr. Timothy Schowalter has succeeded in creating a unique, updated treatment of insect ecology. This revised and expanded text looks at how insects adapt to environmental conditions while maintaining the ability to substantially alter their environment. It covers a range of topics- from individual insects that respond to local changes in the environment and affect resource distribution, to entire insect communities that have the capacity to modify ecosystem conditions.Insect Ecology, Second Edition, synthesizes the latest research in the field and has been produced in full color throughout. It is ideal for students in both entomology and ecology-focused programs. NEW TO THIS EDITION:* New topics such as elemental defense by plants, chaotic models, molecular methods to measure disperson, food web relationships, and more* Expanded sections on plant defenses, insect learning, evolutionary tradeoffs, conservation biology and more* Includes more than 350 new references* More than 40 new full-color figures
