Book Synopsis Plant Strategies and the Dynamics and Structure of Plant Communities by : David Tilman
Download or read book Plant Strategies and the Dynamics and Structure of Plant Communities written by David Tilman and published by Princeton University Press. This book was released on 1988-03-21 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this new approach to understanding the dynamics occurring among plant populations at the community level, Tilman sets forth an exciting hypothesis to aid in explaining the factors operative in vegetation change. He emphasizes nutrient allocation, especially nitrogen and light, as a critical factor in addition to others in accounting for what is referred to as "succession" by most ecologists. Tilman initially presents some basic concepts--plant competition, resource allocation, and succession--followed by his extensive old field experiments on the Minnesota sand plain. These add support to his hypothesis concerning the role of nutrient allocation as a factor involved in vegetation change. Illustrations, including tables and figures, greatly enhance the text. A most readable book, and students of vegetation science will find it a welcome addition to their libraries. It also should find its way to all academic libraries since it is aimed primarily at professional plant ecologists. W.A. Niering Connecticut College--Choice Reviews.

Book Synopsis Positive Species Interactions Among Plants, Microbes, and Insects as Drivers of Ecological Community Properties by : Melissa Renee Lorraine Whitaker
Download or read book Positive Species Interactions Among Plants, Microbes, and Insects as Drivers of Ecological Community Properties written by Melissa Renee Lorraine Whitaker and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: While positive species interactions are increasingly recognized as playing a fundamental role in the ecology and evolution of most organisms, the dynamics of multi-species positive interactions remain poorly understood. My dissertation takes a community ecology approach to investigating positive species interactions among insects, plants, and microbes, asking how associations among one set of organisms affect mutualisms among others sets of interacting organisms. The first chapter experimentally demonstrates the positive effects of plant-rhizobia interactions on aphid growth and honeydew composition. I grew 180 soybean (Glycine max) plants belonging to two strains: a nodulating strain, the nodules of which are colonized by nutrient-fixing bacteria (rhizobia), and a non-nodulating strain that does not harbor rhizobia. Plants were inoculated with soybean aphids (Aphis glycines), and measurements of aphid colony growth and plant traits were taken over three weeks, after which aphid honeydew was collected and chemically analyzed. Aphid colonies grew slightly larger on nodulating plants and honeydew collected from aphids feeding on nodulating plants (i.e. plants that associate with rhizobia) were found to have significantly higher sugar content than aphids feeding on non-nodulating plants. The potential for this result to affect community properties (e.g. ant-aphid interactions) and ecosystem properties (e.g. microbial nitrogen mineralization in the soil) is discussed. Because honeydew is an important factor mediating aphids' interactions with ants, and because ant-aphid interactions are considered keystone interactions in many ecological communities, my second chapter provides an analysis of the arthropod community in the same experimental system. Using a classic community ecology approach, the abundance, diversity, richness, evenness, and community structure of herbivorous and predacious arthropods are compared between plant strains (nodulating and non-nodulating) and experimental treatments. Both the herbivorous and predacious arthropod communities were significantly influenced by the presence of aphids and ants, but results indicate that the additional treatments of aphids and ants negate previously demonstrated positive effects of plant-rhizobia interactions on arthropod community properties. My third chapter provides a taxonomic characterization of the microbiomes of lycaenid caterpillars, an insect group with diverse life histories, diets, and ant associations. Specimens belonging to three subfamilies were collected from the United States, Thailand, and Singapore, and included herbivorous species that facultatively associate with ants and wholly carnivorous taxa that eat homopterans (often under ant attendance). Using high throughput sequencing on an Illumina platform, I used comparative analysis of 16s rRNA gene sequences to characterize and contrast the microbiomes of each specimen. This work is the first to explore the microbial associations of lycaenid butterflies using high throughput culture-independent techniques. This research will be expanded in future work to address questions related to host-symbiont interactions and the possibility that the evolution of diet and ant- association may be microbially mediated in this group. Finally, in addition to my dissertation research, I completed a capstone project in biodiversity informatics and citizen science. In response to the growing popularity of citizen science and biodiversity monitoring projects and the importance of science outreach and education, I developed a mobile tool for natural history education and biodiversity informatics. The resulting iOS application--The Butterfly Guide: Butterflies of the Sacramento Valley, Delta, and San Francisco Bay Area--is both a mobile field guide and a data collection tool, allowing for the acquisition, synthesis, and dissemination of butterfly data by students, naturalists, and citizen scientists. Most importantly, all source code and development materials are freely available as a template for other developers interested in creating similar field guides. This project thereby serves as a prototype with the hope that it will increase opportunities for non-scientists to engage in the natural world, participate in the scientific process, and generate reliable biodiversity data.

Book Synopsis The Fungal Community by : John Dighton
Download or read book The Fungal Community written by John Dighton and published by CRC Press. This book was released on 2005-05-24 with total page 982 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Fungal Community: Its Organization and Role in the Ecosystem, Third Edition addresses many of the questions related to the observations, characterizations, and functional attributes of fungal assemblages and their interaction with the environment and other organisms. This edition promotes awareness of the functional methods of classification over taxonomic methods, and approaches the concept of fungal communities from an ecological perspective, rather than from a fungicentric view. It has expanded to examine issues of global and local biodiversity, the problems associated with exotic species, and the debate concerning diversity and function. The third edition also focuses on current ecological discussions - diversity and function, scaling issues, disturbance, and invasive species - from a fungal perspective. In order to address these concepts, the book examines the appropriate techniques to identify fungi, calculate their abundance, determine their associations among themselves and other organisms, and measure their individual and community function. This book explains attempts to scale these measures from the microscopic cell level through local, landscape, and ecosystem levels. The totality of the ideas, methods, and results presented by the contributing authors points to the future direction of mycology.
Book Synopsis Perspectives on Plant Competition by : James B. Grace
Download or read book Perspectives on Plant Competition written by James B. Grace and published by . This book was released on 2003 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1990, continued requests for copies of Perspectives on Plant Competition by James B. Grace and David Tilman have demonstrated its utility to practitioners and especially to students. The dynamics and outcomes of plant interactions are of increasingly great interest and importance to ecologists and environmental biologists. Ever since the effects of global environmental change have emerged as a major issue, ecologists have increasingly focused their work on predicting the responses of natural systems to environmental changes. This has forced us to confront both the unknowns and the complexity of species interactions. Simply put, it is now clear that, without a better understanding of the mechanisms of plant interactions, we will not be able to predict the responses of communities and ecosystems to elevated nitrogen deposition, to changes in species composition and diversity, to elevated atmospheric CO2, to climate change, or to invasive exotic species. Work on plant interactions has continued unabated of course since the original printing of Perspectives on Plant Competition but the title is generally held to have had a positive effect on subsequent work on plant interactions, both by showcasing the variety of ways in which competition can be approached and by substantially reducing some of the confusion about issues that existed before its publication. It still has an important role to play in guiding future research on plant interactions. Perhaps an additional, continuing value is in the example it serves for the maturation of an important ecological topic. The lasting message of this book is that one cannot fully understand an idea without understanding the perspective upon which it is based, including the systems that have inspired the idea and the finer details of the research goals of those involved. Plant competition will continue to be a multifaceted topic. This book will continue to provide useful guidance for the further exploration of such interactions. "This is certainly a required book for those working on plant competition, and an important reference for ecologists and biologists in general. In many ways, it will be a landmark, providing a snapshot of research at a critical time in the development of this field." Science 249, 1054 "I strongly recommend this well-edited, thoughtful book to all students of population biology and community ecology." Bioscience 41, 178 Jim Grace obtained his Ph.D. from Michigan State University in 1980. He subsequently served on the faculty at the University of Arkansas and Louisiana State University. He joined the US Geological Survey - National Wetlands Research Center in 1992 and currently holds an Adjunct Professorship in Biology at the University of Louisiana in Lafayette. His basic research specialization is in plant ecology, with an emphasis on species interactions, biodiversity, invasive species, and conservation biology. He has been elected to the positions of chair and vice-chair of the Ecological Section of the Botanical Society of America. David Tilman is an experimental and theoretical ecologist interested in biodiversity, in the controls of ecosystem composition, stability and productivity, and in the long-term implications for society of human impacts on global ecosystems. He received his Ph.D. at the University of Michigan in 1976. He immediately came to the University of Minnesota where he now is Regents Professor, holds the McKnight University Presidential Chair in Ecology and is Director of Cedar Creek Natural History Area. He has written two books, edited three books, and published more than 160 scientific papers. In 2001, he was designated the most highly cited environmental scientist of the decade (1990-2000) by the Institute for Scientific Information.

Book Synopsis Below-Ground Interactions in Ecological Processes by : Oren Shelef
Download or read book Below-Ground Interactions in Ecological Processes written by Oren Shelef and published by Frontiers Media SA. This book was released on 2020-01-29 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aboveground interactions between plants and organisms have served as a foundation of ecological and evolutionary theories. Accumulating evidence suggests that interactions that occur belowground can have immense influence on eco-evolutionary dynamics of plants. Despite the increasing awareness among scientists of the importance of belowground interactions for plant performance and community dynamics, they have received considerably less theoretical and empirical attention compared to aboveground interactions. In this eBook we aim to highlight the overlooked roles of belowground interactions and outline their myriad ecological roles, from affecting soil health through impacting plant interactions with above-ground fauna. This eBook with 18 articles and an Editorial includes conceptual contribution together with original research work. The chapters are exploring the roles of belowground biotic interactions, in the context of ecological processes both below- and above-ground.

Available in PDF, EPUB and Kindle. Book excerpt: "A bold and successful attempt to illustrate the theoretical foundations of all of the subdisciplines of ecology, including basic and applied, and extending through biophysical, population, community, and ecosystem ecology. Encyclopedia of Theoretical Ecology is a compendium of clear and concise essays by the intellectual leaders across this vast breadth of knowledge."--Harold Mooney, Stanford University "A remarkable and indispensable reference work that also is flexible enough to provide essential readings for a wide variety of courses. A masterful collection of authoritative papers that convey the rich and fundamental nature of modern theoretical ecology."--Simon A. Levin, Princeton University "Theoretical ecologists exercise their imaginations to make sense of the astounding complexity of both real and possible ecosystems. Imagining a real or possible topic left out of the Encyclopedia of Theoretical Ecology has proven just as challenging. This comprehensive compendium demonstrates that theoretical ecology has become a mature science, and the volume will serve as the foundation for future creativity in this area."--Fred Adler, University of Utah "The editors have assembled an outstanding group of contributors who are a great match for their topics. Sometimes the author is a key, authoritative figure in a field; and at other times, the author has enough distance to convey all sides of a subject. The next time you need to introduce ecology students to a theoretical topic, you'll be glad to have this encyclopedia on your bookshelf."--Stephen Ellner, Cornell University “Everything you wanted to know about theoretical ecology, and much that you didn’t know you needed to know but will now! Alan Hastings and Louis Gross have done us a great service by bringing together in very accessible form a huge amount of information about a broad, complicated, and expanding field.”--Daniel Simberloff, University of Tennessee, Knoxville
