Available in PDF, EPUB and Kindle. Book excerpt: Recent research indicates that plants may be defended by mechanisms activated only after a plant has been challenged by a herbivore. Examines these inducible defenses and provides a framework for future advances in the field. Also serves as a summary and compilation of major studies to date on important areas of plant and insect ecology. While treating both vertebrates and invertebrates it covers mechanisms and models of long- and short-term induction. The impact of inducible phytochemicals on herbivores is extensively discussed as are pesticidal activity of inducible phytochemicals. Covers agricultural implications of inducible phytochemicals.
Download or read book Induced Responses to Herbivory written by Richard Karban and published by University of Chicago Press. This book was released on 2007-12-01 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 or read book The Phytochemical Landscape written by Mark D. Hunter and published by Princeton University Press. This book was released on 2016-08-09 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dazzling variation in plant chemistry is a primary mediator of trophic interactions, including herbivory, predation, parasitism, and disease. At the same time, such interactions feed back to influence spatial and temporal variation in the chemistry of plants. In this book, Mark Hunter provides a novel approach to linking the trophic interactions of organisms with the cycling of nutrients in ecosystems. Hunter introduces the concept of the "phytochemical landscape"—the shifting spatial and temporal mosaic of plant chemistry that serves as the nexus between trophic interactions and nutrient dynamics. He shows how plant chemistry is both a cause and consequence of trophic interactions, and how it also mediates ecosystem processes such as nutrient cycling. Nutrients and organic molecules in plant tissues affect decomposition rates and the fluxes of elements such as carbon, nitrogen, and phosphorus. The availability of these same nutrients influences the chemistry of cells and tissues that plants produce. In combination, these feedback routes generate pathways by which trophic interactions influence nutrient dynamics and vice versa, mediated through plant chemistry. Hunter provides evidence from terrestrial and aquatic systems for each of these pathways, and describes how a focus on the phytochemical landscape enables us to better understand and manage the ecosystems in which we live. Essential reading for students and researchers alike, this book offers an integrated approach to population-, community-, and ecosystem-level ecological processes.
Download or read book Phytochemical Diversity and Redundancy in Ecological Interactions written by John T. Romeo and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diversity within and among living organisms is both a biological impera tive and a biological conundrum. Phenotypic and genotypic diversity is the critical currency ofecological interactions and the evolution of life. Thus, it is not unexpected to find vast phytochemical diversity among plants. However, among the most compelling questions which arise among those interested in ecological phytochemistry is the extent, nature, and reasons for the diversity of chemieals in plants. The idea that natural products (secondary metabolites) are accidents of metabolism and have no biological function is an old one which has resurfaced recently under a new term "redundancy. " Redundancy in the broader sense can be viewed as duplication of effort. The co-occurrence of several classes of phytochemieals in a given plant may be redundancy. Is there unnecessary duplication of chemical defense systems and ifso, why? What selective forces have produced this result? On the other hand, why does the same compound often have multiple functions? At a symposium of the Phytochemical Society of North America held in August 1995, in Sault Ste. Marie, Ontario, Canada, the topic "Phytochernical Redundancy in Ecological Interactions" was discussed. The chapters in this volume are based on that symposium. They both stimulate thought and provide some working hypotheses for future research. It is being increasingly recognized that functional diversity and multiplicity of function of natural products is the norm rather than the exception.
Download or read book Multigenic and Induced Systemic Resistance in Plants written by Tuzun Sadik and published by Springer Science & Business Media. This book was released on 2006-10-26 with total page 538 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants have developed very sophisticated mechanisms to combat pathogens and pestsusingtheleastamountofreservedorgeneratedenergypossible. Theydothis by activating major defense mechanisms after recognition of the organisms that are considered to be detrimental to their survival; therefore they have been able to exist on Earth longer than any other higher organisms. It has been known for the past century that plants carry genetic information for inherited resistance against many pathogenic organisms including fungi, bacteria, and viruses, and that the relationship between pathogenic organisms and hosts plants are rather complex and in some cases time dependent. This genetic information has been the basis for breeding for resistance that has been employed by plant breeders to develop better-yielding disease resistant varieties, some of which are still being cultivated. Single gene resistance is one type of resistance which has been extensively studied by many research groups all around the world using biotechnological methodologies that have been the subject of many books and journal articles; therefore, it is beyond the scope of this book. This type of resistance is very effective, although it can be overcome by the pressure of pathogenic organisms since it depends on interaction of a single elicitor molecule from the pathogen with a single receptor site in the host.
Download or read book Large Herbivore Ecology Ecosystem Dynamics and Conservation written by Kjell Danell and published by Cambridge University Press. This book was released on 2006-05-25 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most large herbivores require some type of management within their habitats. Some populations of large herbivores are at the brink of extinction, some are under discussion for reintroduction, whilst others already occur in dense populations causing conflicts with other land use. Large herbivores are the major drivers for forming the shape and function of terrestrial ecosystems. This 2006 book addresses the scientifically based action plans to manage both the large herbivore populations and their habitats worldwide. It covers the processes by which large herbivores not only affect their environment (e.g. grazing) but are affected by it (e.g. nutrient cycling) and the management strategies required. Also discussed are new modeling techniques, which help assess integration processes in a landscape context, as well as assessing the consequences of new developments in the processes of conservation. This book will be essential reading for all involved in the management of both large herbivores and natural resources.
Download or read book Insect Plant Interactions and Induced Plant Defence written by Derek J. Chadwick and published by John Wiley & Sons. This book was released on 2008-05-23 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insect-Plant Interactions and Induced Plant Defence Chair: John A. Pickett, 1999 This book examines the sophisticated mechanisms that plants use to defend themselves against attack by insects and pathogens, focusing on the networks of plant signalling pathways that underlie these defences. In response to herbivory, plants release a complex blend of as many as 100 volatile chemicals, known as semiochemicals ('sign chemicals'). These act as an airborne SOS signal, revealing the presence of the herbivore to the predators and parasitoids that are its natural enemies. Plants also have endogenous defence mechanisms that can be induced in response to pathogens, and separate chapters deal with systemic acquired resistance, phytoalexins, and the interacting pathways in pathogen and pest resistance. The book discusses underlying biochemical mechanisms by which plant stress leads to the biosynthesis of chemical signals from pools of secondary metabolite precursors, or even from the primary metabolism source. Finally, consideration is given to the possibilities for exploiting these signalling pathways by plant molecular genetics. The use of plant signals and their analogues to switch on defence pathways in crop plants is covered in depth. Bringing together contributions from entomologists, chemical ecologists, molecular biologists and plant physiologists this book is truly interdisciplinary, and will be essential reading for anyone with an interest in agricultural pest control.

Download or read book Insect Plant Biology written by Louis M. Schoonhoven and published by Oxford University Press. This book was released on 2005-12 with total page 441 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Half of all insect species are dependent on living plant tissues, consuming about 10% of plant annual production in natural habitats and an even greater percentage in agricultural systems, despite sophisticated control measures. Plants are generally remarkably well-protected against insect attack, with the result that most insects are highly specialized feeders. The mechanisms underlying plant resistance to invading herbivores on the one side, and insect food specialization on the other, are the main subjects of this book. For insects these include food-plant selection and the complex sensory processes involved, with their implications for learning and nutritional physiology, as well as the endocrinological aspects of life cycle synchronization with host plant phenology. In the case of plants exposed to insect herbivores, they include the activation of defence systems in order to minimize damage, as well as the emission of chemical signals that may attract natural enemies of the invading herbivores and may be exploited by neighbouring plants that mount defences as well." "Insect-Plant Biology discusses the operation of these mechanisms at the molecular and organismal levels, in the context of both ecological interactions and evolutionary relationships. In doing so, it uncovers the highly intricate antagonistic and mutualistic interactions that have evolved between plants and insects. The book concludes with a chapter on the application of our knowledge of insect-plant interactions to agricultural production." "This multidisciplinary approach will appeal to students in agricultural entomology, plant sciences, ecology, and indeed anyone interested in the principles underlying the relationships between the two largest groups of organisms on earth: plants and insects."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.
