Ecological Microcosms


Book Description

Ecological Microcosms is a seminal work which reviews the expanding field of enclosed ecosystem research, and relates the results and models of microcosm studies to general concepts in ecology. Microcosms are miniaturized pieces of our biosphere, ranging from streams and lakes to terraria, agroecosystems, and waste systems. The study of these simplified ecosystems is providing provocative insights into ecological principles as well as issues of environmental management and global stability. The authors have used the well-known thermodynamic approach of H.T. Odum and numerous computer simulations. The book also includes an evaluation of alternative mesocosm approaches for the support of humans in space, as well as appendices to aid in the teaching of environmental concepts using student-created microcosms. Ecological Microcosms will be of interest to ecologists, environmental engineers, policy makers and environmental managers, space scientists, and educators. Robert J. Beyers is a Professor of Biology at the University of South Alabama. Howard T. Odum is Graduate Research Professor of Environmental Engineering Sciences at the University of Florida, and was awarded, with Eugene Odum, the 1987 Crafoord Prize in the Biosciences.




Microcosms


Book Description

In this book, the authors discuss the ecology, biological implications and environmental impact of microcosms. Topics include using microcosms to investigate aspects of plant-bacterial interactions and bacterial evolution; multifactorial microcosm experiments to predict how plant species and assemblages respond to changes in the availability and spatio-temporal heterogeneity of resources like water, light and nutrients; development and optimisation of an aquatic laboratory microcosm for ecotoxicological risk assessment; assessment on transformation of organic pollutants in microcosms; bacterial evolution in simple microcosms; ecology and environmental side-effects of pesticides in tropical microcosms; floating dish microcosms to study the developments of biofilm communities; the role of semiosis and cohesion and sustainability inside microcosms; and soil microcosms and biogeographical research.







Experimental Ecology


Book Description

Experimentation is a dominant approach in contemporary ecological research, pervading studies at all levels of biological organization and across diverse taxa and habitats. Experimental Ecology assembles an eminent group of ecologists who synthesize insights from these varied sources into a cogent statement about experimentalism as an analytical paradigm, placing experimentation within the larger framework of ecological investigation. The book discusses diverse experimental approaches ranging from laboratory microcosms to manipulation of entire ecosystem, illustrating the myriad ways experiments strengthen ecological inference. Experimental ecologists critique their science to move the field forward on all fronts: from better designs, to better links between experiments and theory, to more realism in experiments targeted at specific systems and questions.




Perspectives in Ecological Theory


Book Description

This volume presents an overview of current accomplishments and future directions in ecological theory. The twenty-three chapters cover a broad range of important topics, from the physiology and behavior of individuals or groups of organisms, through population dynamics and community structure, to the ecology of ecosystems and the geochemical cycles of the entire biosphere. The authors focus on ways in which theory, whether expressed mathematically or verbally, can contribute to defining and solving fundamental problems in ecology. A second aim is to highlight areas where dialogue between theorists and empiricists is likely to be especially rewarding. The authors are R. M. Anderson, C. W. Clark, M. L. Cody, J. E. Cohen, P. R. Ehrlich, M. W. Feldman, M. E. Gilpin, L. J. Gross, M. P. Hassell, H. S. Horn, P. Kareiva, M.A.R. Koehl, S. A. Levin, R. M. May, L. D. Mueller, R. V. O'Neill, S. W. Pacala, S. L. Pimm, T. M. Powell, H. R. Pulliam, J. Roughgarden, W. H. Schlesinger, H. H. Shugart, S. M. Stanley, J. H. Steele, D. Tilman, J. Travis, and D. L. Urban. Originally published in 1989. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.




Design and Analysis of Ecological Experiments


Book Description

Ecological research and the way that ecologists use statistics continues to change rapidly. This second edition of the best-selling Design and Analysis of Ecological Experiments leads these trends with an update of this now-standard reference book, with a discussion of the latest developments in experimental ecology and statistical practice. The goal of this volume is to encourage the correct use of some of the more well known statistical techniques and to make some of the less well known but potentially very useful techniques available. Chapters from the first edition have been substantially revised and new chapters have been added. Readers are introduced to statistical techniques that may be unfamiliar to many ecologists, including power analysis, logistic regression, randomization tests and empirical Bayesian analysis. In addition, a strong foundation is laid in more established statistical techniques in ecology including exploratory data analysis, spatial statistics, path analysis and meta-analysis. Each technique is presented in the context of resolving an ecological issue. Anyone from graduate students to established research ecologists will find a great deal of new practical and useful information in this current edition.




Cuatro Ciénegas Ecology, Natural History and Microbiology


Book Description

The aim of this first book is to introduce the readers of the series to why Cuatro Ciénegas Basin (CCB) is so unique, starting with the reason why astrobiologists became interested in this oasis in the first place; namely, the high diversity and abundance of stromatolites and microbial mats in continental waters to be found in the desert oasis. As NASA has long since discovered, the basin may offer the best analog of early Earth. In essence, CCB is a time machine that can take us far back and forth in time. In the respective chapters, the contributing authors explain the extraordinary microbial diversity of Cuatro Ciénegas Basin from various perspectives. In order to do so, they explain their journey as well as the different tools used to unravel the basin’s mysteries, such as: Why are there so many species in a place without food? How has life there survived the enormity of tectonic shifts through the ages, maintaining its ancient marine heritage?




Chaos in the Cosmos


Book Description

'Chaos In The Cosmos' is book 2 in the 'Magic Islands' series. The fun and games of the wicked Purple Wizards' tricks and their wrong doings are taken too far, resulting in an urgency to save Planet Earth from disaster before time runs out for the planet. The story illustrates the way nature can hit out when not heeded or respected, and it shows the impact climate change can have on our planet in extreme temperatures. It sets the scene for young readers to learn and understand the effects of a warmer chaotic world, and aims at promoting such concepts through storytelling and adventure, thus exposing some of the global issues surrounding planetary warming, as narrated and visualized through the eyes of magic and fantasy. Written with much lyrical fun in mind for children, there is, of course, some serious underlying elements... those of fostering climatic awareness, and the realisation our planet is very precious to us all. 'Chaos in the Cosmos,' is a fantasy narrative for children aged between 8 to 12 years. Book 1 - A Spooky Wish Book 2 - Chaos In The Cosmos Book 3 - The Land Of Now And Then




Microcosmos


Book Description

"Microcosmos is nothing less than the saga of the life of the planet. Lynn Margulis and Dorion Sagan have put it all together, literally, in this extraordinary book, which is unlike any treatment of evolution for a general readership that I have encountered before. A fascinating account that we humans should be studying now for clues to our own survival."—From the Foreword by Dr. Lewis Thomas Microcosmos brings together the remarkable discoveries of microbiology in the later decades of the 20th century and the pioneering research of Dr. Margulis to create a vivid new picture of the world that is crucial to our understanding of the future of the planet. Addressed to general readers, the book provides a beautifully written view of evolution as a process based on interdependency and their interconnectedness of all life on the planet.




The Rhizosphere


Book Description

Below the soil surface, the rhizosphere is the dynamic interface among plant roots, soil microbes and fauna, and the soil itself, where biological as well as physico-chemical properties differ radically from those of bulk soil. The Rhizosphere is the first ecologically-focused book that explicitly establishes the links from extraordinarily small-scale processes in the rhizosphere to larger-scale belowground patterns and processes. This book includes chapters that emphasize the effects of rhizosphere biology on long-term soil development, agro-ecosystem management and responses of ecosystems to global change. Overall, the volume seeks to spur development of cross-scale links for understanding belowground function in varied natural and managed ecosystems. - First cross-scale ecologically-focused integration of information at the frontier of root, microbial, and soil faunal biology - Establishes the links from extraordinarily small-scale processes in the rhizosphere to larger-scale belowground patterns and processes - Includes valuable information on ecosystem response to increased atmospheric carbon dioxide and enhanced global nitrogen deposition - Chapters written by a variety of experts, including soil scientists, microbial and soil faunal ecologists, and plant biologists
