Book Synopsis Effects of Resource Distribution on Animal Plant Interactions by : Mark D. Hunter
Download or read book Effects of Resource Distribution on Animal Plant Interactions written by Mark D. Hunter and published by Elsevier. This book was released on 2012-12-02 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aimed primarily at advanced graduate students and professional biologists, this book explores the degree to which animal*b1plant interactions are determined by plant and animal variability. Many of the patterns seen in natural communities appear to result from cascading effects up as well as down the trophic system. Variability among primary producers can influence animal and plant population quality and dynamics, community structure, and the evolution of animal*b1plant interations.

Book Synopsis Population Ecology of Individuals. (MPB-25), Volume 25 by : Adam Lomnicki
Download or read book Population Ecology of Individuals. (MPB-25), Volume 25 written by Adam Lomnicki and published by Princeton University Press. This book was released on 2020-03-31 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: A common tendency in the field of population ecology has been to overlook individual differences by treating populations as homogeneous units; conversely, in behavioral ecology the tendency has been to concentrate on how individual behavior is shaped by evolutionary forces, but not on how this behavior affects population dynamics. Adam Lomnicki and others aim to remedy this one-sidedness by showing that the overall dynamical behavior of populations must ultimately be understood in terms of the behavior of individuals. Professor Lomnicki's wide-ranging presentation of this approach includes simple mathematical models aimed at describing both the origin and consequences of individual variation among plants and animals. The author contends that further progress in population ecology will require taking into account individual differences other than sex, age, and taxonomic affiliation--unequal access to resources, for instance. Population ecologists who adopt this viewpoint may discover new answers to classical questions of population ecology. Partly because it uses a variety of examples from many taxonomic groups, this work will appeal not only to population ecologists but to ecologists in general.

Book Synopsis Interchanges of Insects between Agricultural and Surrounding Landscapes by : B.S. Ekbom
Download or read book Interchanges of Insects between Agricultural and Surrounding Landscapes written by B.S. Ekbom and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: The chapters in this book were developed from some of the lectures presented at a sym posium at the XX International Congress of Entomology held in Florence, Italy in August 1996. The purpose of the symposium was to discuss the impact of evolving modern agricultural landscapes on the insect species, of both economic and ecological importance, that utilize that habitat. Agricultural policy, to some extent, influences the choices that farmers make and thereby the shape of the agricultural landscape. In order to move toward more sustainable agro ecosystems future policy makers will have to consider the history of land use, consumer demands for both environmentally sound and affordable products, and the conservation of biological diversity. I would hope the information contained in this book will help stimulate discussion about the consequences of policy decisions on our agricultural landscapes and their insect inhabitants. I thank all the speakers from the symposium and in particular those that have been able to contribute chapters to this book. There have been many delays, most due to circumstances beyond anyone's control. I would like to express my appreciation to Gloria Verhey and Patrick Dumont for taking care of the book in these final months.

Available in PDF, EPUB and Kindle. Book excerpt: Explore the latest research on biological control! Completely updated for 2004, this new edition examines methods for making agricultural systems less susceptible to insect pests. Containing new findings and reports of strategies, Biodiversity and Pest Management in Agroecosystems, Second Edition will show you how pests can be managed by enhancing beneficial biodiversity using agroecological diversification methods. Biodiversity and Pest Management in Agroecosystems, Second Edition provides you with an essential overview of the role of biodiversity in agriculture and then gets specific, with new and updated information on: the agroecology of pest management plant diversity and pest outbreaks within agroecosystems diversification strategies for pest management how sustainable farming systems are designed You'll also explore: the role of plant diversity on the biology of beneficial insects insect regulation in diverse agroecosystems manipulation of plant diversity in agroecosystems ecological and socioeconomic implications The fact is, many modern agroecosystems are unstable as a consequence of constant human intervention in crop systems which ignore ecological principles. With case studies on a variety of crops and pests, Biodiversity and Pest Management in Agroecosystems, Second Edition explores entomological aspects of agriculture and analyzes the ecological basis for the maintenance of biodiversity. It will familiarize you with the theory and practice of enhancing biological pest control in agricultural systems by managing vegetational diversity via multiple cropping, cover cropping, rotations, and other spatial and temporal designs. With studies on intercropping, cover cropping, weed management, and crop-field border vegetation manipulation, this book covers the effects of these diverse systems on pest population density and the mechanisms underlying pest reduction in polycultures.

Book Synopsis Insect-Plant Biology by : Louis M. Schoonhoven
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.
Book Synopsis The Ecological Farm by : Helen Atthowe
Download or read book The Ecological Farm written by Helen Atthowe and published by Chelsea Green Publishing. This book was released on 2023-06-22 with total page 594 pages. Available in PDF, EPUB and Kindle. Book excerpt: The breakthrough resource for fruit and vegetable growers at every scale who want to go ‘beyond organic’ and build higher soil quality and fertility using fewer inputs through a unique ecosystem-balancing approach “Atthowe’s book takes ecological farming to the next level. It is packed with useful, field-tested, innovative techniques for farming more gently without sacrificing productivity. . . This is the future of farming. I highly recommend this book.”—Ben Hartman, author of The Lean Farm The Ecological Farm is the go-to guide for ecological growing, with a unique focus on reduced tillage, minimizing farm and garden inputs, and pest control. Reflecting the wisdom that farmer, consultant, and educator Helen Atthowe and her late husband, Carl Rosato, gained during decades of farming experience, this book guides readers on how to reduce or eliminate the use of outside inputs of fertilizer or pesticides—even those that are commonly used on certified organic orchards and market gardens. In clear language and with color photographs, charts, and graphs throughout, the book emphasizes the importance of managing the details of an entire growing system over the full life of the enterprise. Based on advances in scientific research in ecological food production, farmers, homesteaders, permaculturists, and gardeners alike will learn methods to: design a farm system that maintains a growing root in the soil year-round to feed the microbial community instead of just crops. strengthen the “immune system” of a farm or garden supply crop needs using only on-farm inputs such as cover crops and living mulch maximize the presence of beneficial insects and microbes that support healthy crop development minimize ecological impact in dealing with insect pest and disease problems The Ecological Farm also features a crop-by-crop guide to growing more than 25 of the most popular and profitable vegetables and fruits, including specific management advice for dealing with pests and diseases. The Ecological Farm makes complex, sometimes messy, ecological concepts and practices understandable to all growers, and makes healthy farming—in which nature is invited to participate—possible. "[This book] will guide all of us as we learn to farm in harmony with an ecosystem and to become obedient to the whole rather than being distracted by the urge to tinker with the parts.” —Wes Jackson, cofounder and president emeritus, The Land Institute

Book excerpt: Their natural enemies largely determine the population size and dynamic behavior of many plant-eating insects. Any reduction in enemy number can result in an insect outbreak. Applied biological control is thus one strategy for restoring functional biodiversity in many agroecosystems. Predators and Parasitoids addresses the role of natural enemies i
Book Synopsis Variable plants and herbivores in natural and managed systems by : Robert Denno
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.

Book Synopsis Pollination Biology by : Leslie Real
Download or read book Pollination Biology written by Leslie Real and published by Elsevier. This book was released on 2012-12-02 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pollination Biology reviews the state of knowledge in the field of pollination biology. The book begins by tracing the historical trends in pollination research and the development of the two styles of pollination biology. This is followed by separate chapters on the evolution of the angiosperms; the evolution of plant-breeding systems; the geographical correlations between breeding habit, climate, and mode of pollen transfer; and sexual selection in plants. Subsequent chapters examine the process of sexual selection through gametic competition in Geranium maculatum; the effects of different gene movement patterns on plant population structure; the foraging behavior of pollinators; adaptive nature of floral traits; and competitive interactions among flowering plants for pollinators. The book is designed to provide useful material for advanced undergraduate and graduate students wishing to familiarize themselves with modern pollination biology and also to provide new insights into specific problems for those already engaged in pollination research. The book is intended to be used for both teaching and research.
