Download or read book Herbivory written by Breno Barros and published by BoD – Books on Demand. This book was released on 2013-02-27 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies of herbivory provide important insights into fundamental questions in many areas of the biological sciences. The focus on natural systems is more effective for the prediction of potential changes in ecosystems, given that agricultural systems are designed to create an equilibrium that optimizes the productive process. Given the ramifications of the processes related to herbivory, studies based on complementary approaches are necessary for a better understanding of the different aspects of the ecological process. This book attempts to expand on these different aspects of herbivory by presenting a multidisciplinary approach to a number of different themes, focusing on topics that range from basic research in natural habitats to the intrinsic relationships between animals and plants in agricultural systems.
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.

Book excerpt: This book attempts to summarize what we know about inseet-plant relationships without beeoming too involved with untestable hypo- theses. It is not intended to be eomprehensive and we have deliberately excluded diseussion of aquatie organisms and fungi. Our definition of inseet herbivores is intentionally broad. It includes all inseets whieh feed on plants, although we have emphasized those whieh feed primarily on the photosynthetie tissues. Some referenee is made to seed predation but pollination eeology is excluded. We thank Ors P.H. Smith and M. Luxton for their helpful eommenb on the manuseript but we accept full responsibility for any mistakes whieh may remain. Finally, we thank the various publishers and a uthor who gave us permission to use copyright material. 7 I Introduction The net primary produetion of the 300000 speeies of vaseular plant whieh inhabit the dry land surfaee of the earth has been estimated at 9 about 115 x 10 t per annum. This represents a massive resouree potentially available for exploitation by the herbivorous inseets, which themselves probably number in exeess of 500000 species.

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 Evolutionary Ecology of Plant Herbivore Interaction written by Juan Núñez-Farfán and published by Springer Nature. This book was released on 2020-07-30 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant-herbivore interactions are a central topic in evolutionary ecology. Historically, their study has been a cornerstone for coevolutionary theory. Starting from classic ecological studies at the phenotypic level, it has since expanded to molecular and genomic approaches. After a historical perspective, the book’s subsequent chapters cover a wide range of topics: from populations to ecosystems; plant- and herbivore-focused studies; in natural and in man-modified ecosystems; and both micro- and macro-evolutionary levels. All chapters include valuable background information and empirical evidence. Given its scope, the book will be of interest to both students and researchers, and will hopefully stimulate further research in this exciting field of evolutionary biology.

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 The effects of herbivory and competition on Senecio inaequidens DC Asteraceae an invasive alien plant written by Christoph Scherber and published by GRIN Verlag. This book was released on 2002-12-07 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diploma Thesis from the year 2002 in the subject Biology - Ecology, grade: 1,0 (A), University of Rostock (Institute for Botany), language: English, abstract: Since the end of the 19th century, overall per-capita mobility of humans has increased significantly, leading to increased rates in human-mediated transportation of animal and plant species. The rapid spread of alien organisms, however, may lead to quick and unpredictable changes in ecosystems. Senecio inaequidens DC. (Asteraceae) is an invasive alien plant from South Africa that was first introduced to Europe 100 years ago and is characterized by an exceptionally fast rate of spread; it contains pyrrolizidine alkaloids that are toxic to invertebrates, livestock and humans. In the study presented here, laboratory, greenhouse and field experiments on the biology of Senecio inaequidens were conducted, in order to find out if and how herbivory and plant competition influence growth, survival and reproduction of this plant. Specifically, the presence of vertebrate herbivores, molluscs, insects and plant competitors was experimentally manipulated using full factorial and split-plot designs. All experiments were performed at Imperial College, Silwood Park, about 30 km west of London (UK). Growth and fecundity of Senecio inaequidens were significantly affected by interspecific competition. Vertebrate herbivory only had a significant effect when a closed vegetation cover was present. On artificially disturbed plots, Senecio inaequidens showed high capability to overcompensate for herbivory. Mollusc herbivory significantly reduced fecundity of S. inaequidens. Different ecotypes of Senecio inaequidens showed different amounts of herbivore damage. One of the most remarkable results of this study was that Longitarsus jacobaeae, a native specialist leaf beetle, freely colonized Senecio inaequidens, indicating that native herbivores might be suitable biocontrol agents of invasive alien plants in the future. Host switching from indigenous to invasive alien plant species in oligophagous insect herbivores may be more common than generally thought. The results of this study indicate that Senecio inaequidens is likely to invade and persist in heavily grazed or disturbed grassland ecosystems in the near future; because of the toxic compounds this plant contains, it would be advisable to design a preventive management program and to inform the public about the consequences that might be associated with the invasion of this plant.
