Download or read book Variable plants and herbivores in natural and managed systems written by Robert Denno and published by Elsevier. This book was released on 2012-12-02 with total page 735 pages. Available in PDF, EPUB and Kindle. Book excerpt: Variable Plants and Herbivores in Natural and Managed Systems examines individual, population, species, and community responses of herbivores to plant variation, with emphasis on insects, fungi, bacteria, and viruses. It is divided into five parts encompassing 18 chapters that discuss variability as a mechanism of defense used by plants against their parasites and the effects of variability on herbivores at several different levels of complexity. After a brief discussion on plant-herbivore interactions, the first part of this book considers sources of within-plant variation and effects on the distribution and abundance of herbivores. Part II examines interplant variation, the co-evolutionary problems it poses for herbivores, and the ecological and evolutionary responses of these animals. It discusses the effects of host-plant variability on the fitness of sedentary herbivorous insects. Part III discusses the role of host variability in the evolution of feeding specialization, genetic differentiation, and race formation. The importance of host variation to the organization of herbivore communities and the manipulation of host-plant variability for the management of herbivore pest populations are presented in the remaining parts. This book will be helpful to agriculturists, silviculturists, biologists, and researchers who wish to expand their knowledge in dynamics of plant-herbivore relationships.

Download or read book Plant Resistance to Herbivores and Pathogens written by Robert S. Fritz and published by University of Chicago Press. This book was released on 2012-07-15 with total page 601 pages. Available in PDF, EPUB and Kindle. Book excerpt: Far from being passive elements in the landscape, plants have developed many sophisticated chemical and mechanical means of deterring organisms that seek to prey on them. This volume draws together research from ecology, evolution, agronomy, and plant pathology to produce an ecological genetics perspective on plant resistance in both natural and agricultural systems. By emphasizing the ecological and evolutionary basis of resistance, the book makes an important contribution to the study of how phytophages and plants coevolve. Plant Resistance to Herbivores and Pathogens not only reviews the literature pertaining to plant resistance from a number of traditionally separate fields but also examines significant questions that will drive future research. Among the topics explored are selection for resistance in plants and for virulence in phytophages; methods for studying natural variation in plant resistance; the factors that maintain intraspecific variation in resistance; and the ecological consequences of within-population genetic variation for herbivorous insects and fungal pathogens.

Download or read book Insect Plant Biology written by Louis M. Schoonhoven and published by OUP Oxford. This book was released on 2005-12-01 with total page 440 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 possess defences that are effective against almost all herbivorous insect species. Host-plant specialization, observed in over 80% of these animals, appears to be an effective adaptation to breach these defence systems. The mechanisms underlying plant defence to invading herbivores on the one side, and insect adaptations to utilize plants for nutrition, defence and shelter on the other, are the main subjects of this book. 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. For insects, they include complex bevioural adaptations and their underlying sensory systems (with their implications for learning and nutritional plasticity), as well as the endocrinological aspects of life cycle synchronization with host-plant phenology. Insect-Plant Biology discusses the operation of these mechanisms at the molecular and organismal levels and explicitly puts these in the context of both ecological interactions and evolutionary processes. In doing so, it uncovers the highly intricate antagonistic as well as 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 biology, agricultural entomology, ecology, and indeed anyone interested in the principles underlying the relationships between the two largest groups of organisms on earth: plants and insects.

Download or read book Chemical Ecology of Insects written by William J. Bell and published by Springer. This book was released on 2013-11-27 with total page 523 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our objective in compiling a series of chapters on the chemical ecology of insects has been to delineate the major concepts of this discipline. The fine line between presenting a few topics in great detail or many topics in veneer has been carefully drawn, such that the book contains sufficient diversity to cover the field and a few topics in some depth. After the reader has penetrated the crust of what has been learned about chemical ecology of insects, the deficiencies in our understanding of this field should become evident. These deficiencies, to which no chapter topic is immune, indicate the youthful state of chemical ecology and the need for further investigations, especially those with potential for integrating elements that are presently isolated from each other. At the outset of this volume it becomes evident that, although we are beginning to decipher how receptor cells work, virtually nothing is known of how sensory information is coded to become relevant to the insect and to control the behavior of the insect. This problem is exacerbated by the state of our knowledge of how chemicals are distributed in nature, especially in complex habitats. And finally, we have been unable to understand the significance of orientation pathways of insects, in part because of the two previous problems: orientation seems to depend on patterns of distri bution of chemicals, the coding of these patterns by the central nervous system, and the generation of motor output based on the resulting motor commands.
Download or read book Neotropical Gradients and Their Analysis written by Randall W. Myster and published by Springer Nature. This book was released on 2023-03-31 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: The importance of the Neotropics to the world's climate, biogeochemical cycling and biodiversity cannot be questioned. This book suggests that gradients are key to understanding both these issues and Neotropical ecosystem structure, function and dynamics in general. Those gradients are either spatial, temporal or spatio-temporal, where many temporal and spatio-temporal gradients are initiated by disturbances (e.g., tree-fall, landslide, cultivation). And in particular for the Neotropics, three large spatial gradients - latitude, longitude, altitude (elevation) - are of critical importance. The editor has over 30 years of experience investigating Neotropical gradients in Costa Rica, Puerto Rico, Peru and Ecuador, and has published 5 previous books on different aspects of the Neotropics. Once again he has assembled top-shelf Neotropical scientists and researchers, here to focus on gradients: their nature, interactions and how they structure ecosystems.

This book was released on 2007-08-19 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: For more than 20 years insect/plant relations have been a focus for studies in ecology and evolution. The importance of insects as crop pests, and the great potential of insects for the biological control of weeds, have provided further impetus for work in this area. All this attention has resulted in books on various aspects of the topic, and reviews and research papers are abundant. So why write another book? It seems to us that, in the midst of all this activity, behavior has been neglected. We do not mean to suggest that there have not been admirable papers on behavior. The fact that we can write this book attests to that. But we feel that, too often, behavior is relegated to a back seat. In comparison to the major ecological and evolutionary questions, it may seem trivial. Yet the whole process of host-plant selection and host-plant specificity amongst insects depends on behavior, and selection for behavioral differences must be a prime factor in the evolution of host-plant specificity. In writing this book, we hope to draw attention to this central role of behavior and, hopefully, encourage a few students to attack some of the very difficult questions that remain unanswered.
